Description
RELATED PATENT APPLICATION
[0001] This application is a continuation-in-part of co-pending
U.S. patent application Ser. No. 13/790,548, filed on Mar. 8, 2013
and entitled "MOBILE TELEPHONE DOG TRAINING TOOL AND METHOD," by
inventors James C. Bianchi and Robert W. Holland, describes
exemplary methods and systems and is incorporated by reference in
its entirety.
BACKGROUND OF THE INVENTION
[0002] 1. Field of the Invention
[0003] The present invention relates in general to the field of dog
training, and more particularly to a mobile telephone dog training
tool and method.
[0004] 2. Description of the Related Art
[0005] Kali Bianchi recently completed an upland game bird grand
slam. Kali is a French Brittany, L'Epagneul Breton. Her story is
captured in "It's all about the Dog," published in the Publication
of the Club de l'Epagneul Breton of the United States, Second
Semester 2012, Issue 35. Kali never had formal training to speak of
Kali, like most successful gun dogs, had good genetic cloth woven
into a hardy hunting companion by her love of her master.
[0006] Although Kali lacks formal training credentials, she did
learn some basic skills the hard way at the old-fashioned South
Texas school of hard knocks. She learned to listen when told to
come or she would get chased down. She learned to avoid
rattlesnakes after getting whacked on the nose by a de-fanged
rattler. She learned that skunks stink and that dogs that smell
like skunk do not get love. She learned that when the boots and gun
came out, she better pick up and go because good things usually
happen. Kali learned where birds hide with time and freedom on her
hunts to investigate promising cover. When the cover was taller
than her short stature, a bell around her neck and swishing weeds
generally indicated her whereabouts. During the excitement of a
hunt, the absence of noise meant a point and Kali had learned to
find her quarry.
[0007] Kali grew up on a South Texas ranch with lots of room to
roam and learn about the outdoors. Many gun dog pups do not share
Kali's good fortune. City dogs that do not get to experience the
outdoors as Kali did often have difficulty adapting to hunting
unless they receive some sort of formal training. Professional
kennel trainers who train many dogs simply do not have time for
old-fashioned, hands-off training like that Kali received. If, for
example, a professional kennel trainer had to chase down every pup
that failed to come when called, not much training would get done.
Instead, professionals typically use training tools that help teach
dogs what to do and what not to do.
[0008] One prominent dog training tool is the shock collar, which
applies an electric shock to a dog's skin in response to a remote
activation at a radio controller held by a trainer. After a dog
learns the meaning of a command, like "come," application of a
shock helps to ensure compliance when the dog hesitates or chooses
not to listen. Some shock collars include or work with Global
Position Satellite (GPS) receivers that aid a trainer in the field
by letting the trainer track the dog's position on a display
included with the radio controller. Examples of such systems
include the GARMIN ASTRO and ALPHA systems. Some pet recovery
systems use GPS to track lost dogs and report the position of the
dog to an owner through a website or smartphone application, such
as the SPOTLIGHT pet recovery system available from the American
Kennel Club. After a dog learns verbal commands, advanced training
usually involves the use of whistles to send commands over long
distances. A good trainer who uses training tools in an appropriate
manner can have a dog with smart genes trained to hunt in a month
or two.
[0009] One difficulty with training dogs using shock collars is
that dogs become "collar smart." If a dog figures out that he only
gets shocked when a collar is on, he soon learns not to behave
absent the collar. Worse, if the dog learns that the trainer has a
shock collar but the master does not, the dog might decide to hear
the trainer but not the master--who, incidentally, pays the trainer
and buys the dog food. Most city dwellers burn years of kitchen
passes when they buy an expensive hunting dog. If that dog won't
hunt, the poor fellow has to do a load of dishes to pay for an
expensive training collar. Ironically, once he gets the collar and
puts it on the dog, he will probably not have to use it more than a
couple of times to teach the dog to listen.
[0010] Simple old-fashioned training worked with Kali, but that
bell around her neck has made her hard of hearing in her old age;
as a result, the whistle too often goes unheard. New-fangled
training tools work and help to make hunting more pleasurable for
both the dog and his master. A hunter should not have to spend a
lifetime of kitchen passes to have training tools--bells and
whistles included--that work at home, work simply, and work
well.
SUMMARY OF THE INVENTION
[0011] Therefore a need has arisen for a system, apparatus and
method which adapt a mobile telephone to work as a dog training
tool.
[0012] In accordance with the present invention, a system and
method are provided which substantially reduce the disadvantages
and problems associated with previous methods and systems for
training a dog. A training application executing on a mobile
computing platform, such as a mobile telephone or tablet computer,
provides interactions with a training module deployed at a dog
collar to perform training functions. Processing, display and
communication resources of a mobile telephone are leveraged to
provide a dog training system that is simple, reliable and not
costly.
[0013] More specifically, in one embodiment, a mobile telephone
processor executes a training application that coordinates training
information and actions for training a dog, such as a pointer bird
dog. The training application communicates with a dog collar using
existing WWAN, WLAN and/or WPAN interfaces of the mobile telephone.
The dog collar includes a GPS receiver that sends dog position
information to the training application for presentation on the
mobile telephone display, such as with a map of a hunt boundary
that shows the relative position of the mobile telephone to the
dog, to other dog collars and to other mobile telephones interfaced
through an ad hoc, client/server or other type of WLAN supported by
an 802.11 interface or by a mobile telephone circuit Internet
interface transmitted through a mobile telephone service provider
network. A shock device on the collar provides corrective stimulus
to the dog based on a wireless signal issued from the mobile
telephone. A headset and handset interface with the mobile
telephone through a WPAN interface so that an end user may issue
commands to the mobile telephone and listen to information from the
mobile telephone in a hands-off mode. For instance, a wireless
microphone accepts a verbal command "where dog?" to the training
application running on the mobile telephone. The training
application responds to the command by determining the dog position
from the collar GPS retrieved through a text message sent by a WWAN
mobile telephone circuit. Once the training application receives
the dog's GPS position, the training application issues an audible
"100 yards west" to the end user through a wireless headset Voice
over Internet Protocol (VoIP) and videoconferencing supported
through a WLAN or WWAN Internet interface allows a hunter to
communicate verbally with a dog over an extended distance through a
speaker of the collar and to see via a remote camera what the dog
is pointing.
[0014] In one alternative embodiment, power consumption at a collar
and radio transmission interference with communications of a collar
are reduced by selectively suppressing or otherwise altering
communication of position information from the collar. For
instance, a training application executing on a mobile telephone
assigns different frequencies and/or time slots to each of plural
collars for communicating position information to an adapter or to
a mobile telephone. A tunable transceiver of an adapter tunes radio
frequencies for communicating with each of plural collars and
synchronizes communications with a time slot assignment for each
collar. Collars power down to a reduced-power consumption standby
state, such as by powering down a collar transceiver, outside of a
time slot assigned to the collar for transmission, thus preserving
battery charge at the collar. Transmissions at a collar during time
slots for the collar are selectively suppressed based upon changes
in position of the collar relative to a previous transmission, or
based on other predetermined factors. For instance, if a dog is on
point then a collar suppresses position transmissions scheduled for
one or more time slots while the dog's position remains relatively
immobile, such as within 5 meters of the last position
transmission. As another example, if a dog's velocity vector
remains constant, the collar suppresses position transmissions
since a virtual inertial navigation system on a mobile phone can
track position based on a velocity vector determined from
accelerations and orientation measured at the collar or determined
from a history of GPS positions at plural times. An adapter listens
during each time slot in case an update is transmitted from a
collar and tracks reliability of position information by having
position updates at minimal intervals, such as every minute. In one
embodiment, a GPS receiver clock signal is used as a reference
clock for collar, adapter and ad hoc 802.11 (b, g or n)
communications to maintain synchronous communications, reduce
interference and improve the precision at which a collar and
adapter can sleep, wake and communicate with each other.
Alternatively, a collar wakes at times known to the adapter so that
the adapter can transmit to the collar when position information is
desired. In one example embodiment, Bluetooth (or other WPAN or
alternatively WLAN) communications directly between a mobile
telephone and a collar allow sleep of a UHF/VHF transceiver on the
collar and on an adapter as long as Bluetooth pairing is
maintained, such as anytime a collar comes within 10M or so of a
paired mobile telephone.
[0015] The present invention provides a number of important
technical advantages. One example of an important technical
advantage is that the processing and communication capabilities of
a smartphone are leveraged to enhance dog training with
communications to a dog collar. Knowing the position of a dog and
other hunters through mobile telephone communications enhances dog
training and hunter safety. Hands-off control of dog activity
through wireless peripherals of a smartphone allows a hunter to
perform dog training activities without fumbling for a phone or
other device. Leveraging smartphone capabilities to interact with a
dog collar provides top-rate performance at an everyman cost
controllable by an end user, who chooses whether to rely on basic
mobile telephone WLAN 802.11 capabilities with minimal hardware
costs or to rely on more expensive and expansive capabilities
provided by interacting with a dog collar over a WWAN mobile
telephone account or with an adapter that extends the range of
direct radio communications by the mobile telephone to the dog
collar.

DETAILED DESCRIPTION
[0028] Mobile telephones provide a dog training tool by interacting
with a wireless communication module included on a collar on the
dog. Depending upon the needs and desires of the dog's master, the
mobile telephone provides short or long range training assistance,
such as presentation of a GPS location of the dog relative to the
master and stimulation to the dog from a shock collar or other
training aid located on the collar. A training application running
on the mobile telephone provides training functions that coordinate
communications with one or more dog collars and with one or more
other mobile telephones. For example, an ad hoc network within a
hunting boundary is defined by plural training applications running
on plural mobile telephones to provide enhanced coordination of dog
training activities. The training application leverages
capabilities generally included in mobile telephones so that
advanced features are provided without costly specialized hardware.
Mobile telephones, also known as cell phones or cellular phones,
will work with a remote dog collar as envisioned herein by using
existing wireless capabilities of the mobile telephone to
communicate directly with a dog collar by a radio communication
from the mobile phone directly to the dog collar and from the dog
collar directly to the mobile phone. Generally, a mobile telephone
has a form factor that provides a telephone handset, a touchscreen
display to present information and accept inputs, and at least a
WWAN transceiver to communicate wirelessly with a mobile telephone
service provider network, such as with voice telephone
communications, text message communications and data Internet
communications like a web browser. In addition, a mobile telephone
usually includes an 802.11 transceiver in the 2.4 and/or 5 GHz band
to communicate through a wireless local area network (WLAN) and to
communicate via short range wireless personal area network (WPAN)
Bluetooth interfaces and a 60 GHz short range antenna for WPAN
peripheral communications. Other types of mobile computing devices
that include similar capabilities may also be used with the dog
collar describe herein, such as tablet computing devices equipped
with WWAN and WLAN capabilities.
[0029] Referring now to FIG. 1, an example is depicted of a mobile
telephone dog training system deployed in a hunting environment.
Plural hunters 10 are deployed within a hunt boundary 12, each with
a mobile telephone 14 that communicates through at least one
wireless network. A base station 16 located at a truck 18 may be a
mobile telephone or other computing device, such as a laptop or
tablet computer, having an oversized antenna and amplified wireless
signal to act as a relay or repeater station between mobile
telephones 14 or between network communications, such as a WWAN and
WLAN communication. Although the example embodiment uses mobile
telephones 14 with hunters 10, in alternative embodiments, other
computing devices may be used. Examples of mobile telephones 14
include APPLE iPhones, SAMSUNG GALAXY phones or other types of
smartphones. Examples of base station 16 include APPLE iPADs,
ANDROID-based tablets or other portable computer systems, such as
clamshell laptop devices. In one example embodiment, hunt boundary
12 is the training area of a kennel so that base station 16 is a
fixed desktop computer system.
[0030] One or more dogs 20 are deployed in hunting boundary 12,
such as to hunt one or more areas of cover 22 for game birds like
quail or pheasant. Each dog has a collar 24 that includes a
communication module for communicating with mobile telephones 14
and each collar has a training module for providing a training
function coordinated with mobile telephones 14. Communications
between mobile telephones 14, base station 16 and collars 24 are
supported in a number of different manners depending on the types
of communication bands and protocols that are supported by mobile
telephones 14 and collars 24. In one embodiment, a wireless local
area network (WLAN) device, a wireless wide area network (WWAN)
device and a wireless personal area network device (WPAN) are
selectively included on each of mobile telephones 14 and collars 24
by assembly of one or more appropriately configured wireless
communication modules to collar 24. Wireless communication
coordinated through one or several of these wireless communication
devices provides training applications running on mobile telephones
14 and base station 16 with training information for each other and
collars 24, such as GPS positions, and with a medium for sending
training commands, such as shock collar stimulus.
[0031] One example of wireless communications is communicating
training information and commands between a collar 24 and a mobile
telephone 14 through an IEEE 802.11(n) ad hoc or server/client WLAN
interface. For instance, a training application on a mobile
telephone 14 acts as a server and one or more collars 24 act as
clients that send the server GPS position information, images from
a camera aligned with a direction of a point for the dog 20 wearing
the collar 24, a point alert from detection of lack of motion with
an accelerometer in the collar 24, or other types of training
information. The mobile telephone 14 server sends training commands
to the one or more collars 24 that issue an electric shock or other
stimulation at the collar, issue an oral command from a speaker on
the collar, such as with a VoIP interface or with stored oral
commands in a memory on the collar 24, or issue other types of
commands. In an outdoor line-of-sight environment, an 802.11(n)
WLAN interface has a range of approximately 250 m. If a collar 24
becomes out-of-range from one mobile telephone 14, then a second
mobile telephone 14 that receives communications with the collar 24
and the other mobile telephone 14 can relay the training
information and commands between the out-of-range collar and mobile
telephone. Further, a WLAN interface between two or more mobile
telephones 14 allows VoIP communication between the mobile
telephones 14 so that hunters verbally communicate with each other.
Although the example embodiment describes the use of 802.11(n) in
the 5 GHz frequency range, in alternative embodiments, 802.11(b) or
(g) may be used with a possible increased range in the 2.4 GHz
frequency range. In one example embodiment, a secured 802.11
network protected by a key or with HTTPS protocol may be used to
avoid intrusion by others in the WLAN.
[0032] If a collar 24 becomes out of range for a WLAN interface
with 802.11(n), WWAN communications may be used both with and
without coordination by a cell phone tower 26. For instance, in
remote areas mobile telephone service is sometimes not available or
not reliable. In a situation where cell phone tower 26 is
available, training applications on each mobile telephone 14 may
use an Internet Protocol (IP) interface through a mobile telephone
provider circuit to perform the same types of communications as are
available through WLAN communications as described above. For
instance, a VoIP, SKYPE or FACETIME communication will allow images
and/or commands to be communicated between a collar 24 and a mobile
telephone 20. As an alternative, text messages may be used to
communicate information, such as with simple text, in an XML format
or as a script executable by the training application. As an
example, a collar 24 sends a text message with a GPS position at
predetermined time intervals, such as every 10 seconds. As an
alternative example, to save battery power at collar 24, a text
message with a GPS position is sent based upon at least a
predetermined change in position. For instance a text message is
sent every 10 seconds unless the collars position has not changed
by more than 10 feet, in which case no text message is sent until a
position change of greater than 10 feet is detected or a greater
time period has elapsed, such as another minute. This saves battery
power during rest periods or when a dog is on point. Text messages
may include attachments sent from a collar, such as an image
captured by a camera associated with a collar. Text messages sent
to a collar may include commands, such as a direction for the dog
to turn, which is issued as an audible command by a speaker to have
the dog 20 move in a desired direction. In one embodiment, a collar
24 intercepts IP packets or text messages sent from a mobile
telephone by knowing the mobile telephone's network communication
security codes so that the IP packet or text message need not
transfer through a phone circuit at all. In alternative
embodiments, other types of direct two-way communications may be
accomplished between a mobile telephone 14 and a collar 24 with the
WWAN or the WLAN frequency and protocol in the absence of mobile
telephone service through a cell tower 26, such as through
coordination with a mobile telephone service provider. One example
is to re-program a WNIC of a mobile telephone to provide analog
signals in the WWAN or WLAN frequencies to allow the mobile
telephone to be used like a touch to talk service that mimics
walkie talkie behavior or a remote control (RC) transceiver device.
As one example, a WWAN type service may be provided with a WIMAX
type of protocol, which provides approximately 1 mile of range.
[0033] A WPAN has a short range, such as that provided by 60 GHz
frequency range protocols, Bluetooth or similar short range
communication devices that support peripherals like wireless
headsets for mobile telephones. In one example, a wireless headset
is used by the training application running on the mobile telephone
to issue audible information for a hunter or accept commands from a
hunter. For instance, a lock tone is provided when the training
application receives an indication from a collar that a dog as gone
to point. The tone beeps at varying frequencies and with other
alterations in sound to guide the hunter to the point, such as
higher frequency tones when the mobile telephone is moving closer
to the collar and lower frequency tones when the mobile telephone
is moving further from the collar. A flush tone issues when the
hunter reaches the location of the point as a warning to the hunter
and as a warning to other hunters who have mobile telephones
wirelessly interfaced with the hunter's mobile telephone or the
dog's collar. As another example, a wireless handset coupled with
an armband accepts inputs to buttons programmable by the hunter to
accomplish training tasks, such as issuing stimulation from a shock
device. As another example, a wireless camera mounted on top of the
dog's head communicates images to a collar 24 so that the camera
need not have a wired connection to the collar 24.
[0034] Hunt boundary 12 may be predefined before a hunt so that
collars 24 will issue audible warnings if a dog attempts to leave
the boundary, followed by stimulation. The boundaries and a map of
the hunt area are stored on mobile telephone 14 ahead of time, such
as from the Internet, in case phone service is not available to
download a map during a hunt, such as at a remote location outside
of the range of a mobile telephone service provider network. Hunt
boundaries 12 may be programmed in memory of each collar 24 for an
automated wireless fence around the hunt area enforced by logic at
the collar or may be monitored automatically by a training
application so that warnings and stimulations are sent through the
WLAN or other communication medium as needed based upon a collar's
position. In alternative embodiments, a base station 18 may be used
to define a wireless fence at a hunter's home for use of the system
when not hunting. For instance, the base station activates a "home"
boundary loaded in memory of the collar so that logic on the collar
can issue a stimulation if the position of the collar approaches,
reaches or exceeds the home boundary. The boundary may be
re-programmed as desired through a WLAN interface between the base
station and collar. Breach of the boundary can also be programmed
to notify the dog owner via mobile telephone that the escape has
occurred and reduce the amount of time required to retrieve the
wandering dog and the associated stress.
[0035] Referring now to FIG. 2, a block diagram depicts a mobile
telephone dog training system 28. Mobile telephone 14 is a
smartphone having a CPU 30 and memory 32 that cooperate to execute
instructions and present information as visual images at a
touchscreen display 34. A communications module 36 cooperates with
CPU 30 to perform smartphone communications. A WWAN communication
device establishes communication with a WWAN, such as a mobile
telephone service provider network that supports telephone circuit,
text and Internet-type data interfaces. A WLAN communication device
40 establishes communication with a WLAN, such as an 802.11 network
that supports Internet-type data interfaces. A WPAN communication
device 42 establishes communication with a WPAN, such as Bluetooth
or a 60 GHz band in a tri-band or WiGig network interface. Mobile
telephone 14 includes a variety of other devices commonly found in
smartphones, such as speaker 44 that outputs audible sounds, a
microphone 46 that captures audible sounds and a GPS receiver 48
that determines a position of the device from GPS signals.
[0036] Mobile telephone 14 adapts for use as a dog training system
by executing instructions of a training application 50 stored in
memory 32, which coordinates the use of hardware and software of
mobile telephone 14 for performing dog training functions. For
example, training application 50 coordinates communication with dog
collar 24 through communication module 36. In the example
embodiment, dog collar 24 has a removably coupled wireless
communication module 52 that couples to a training module 54 so
that an end user can select the type of communications that the
mobile telephone will have with collar 24. For instance, wireless
communication module 52 may have single or plural types of
receivers or transceivers for supporting different types of
communications selected by an end user with different frequency
bands and communication protocols. In one example embodiment,
wireless communication module 52 is an analog or digital receiver,
transmitter or transceiver radio in the amateur UHF or VHF radio
bands that communicates with an adapter for the mobile telephone 14
as set forth in FIG. 3. In another example embodiment, wireless
communication module 52 is a WWAN receiver, transmitter or
transceiver that communicates in the WWAN band and protocol of
mobile telephone 14. In another example embodiment, wireless
communication module 52 is a WLAN receiver, transmitter or
transceiver that communicates in a WLAN band and protocol of mobile
telephone 14. Various combinations of receivers and transmitters
may be couple to training module 14 as desired by an end user,
including plural separate communication modules 52 each of which
provide a different type of communication. For example, in one
embodiment a WWAN transmitter permits sending of text messages to
mobile telephone 14 with GPS position information while a WLAN
receiver permits reception of shock collar stimulus commands. As
another example, a WWAN receiver obtains a time stamp from a cell
tower also in use by mobile telephone 14 so that the timeliness of
commands sent through a WLAN interface can be verified at collar
24--this prevents delayed application of a shock stimulus sent by a
WLAN command, which could otherwise correct a dog when the dog is
no longer performing an inappropriate action.
[0037] Training module 54 may include a variety of components that
support training functions in cooperation with training application
50. The training functions may be in one contiguous housing
assembled from several separate housings to allow selection by an
end user of desired functions. One example component is a GPS
receiver 56, which determines the position of collar 24 from a GPS
signal and provides the position information to mobile telephone 14
through wireless communication module 52. Training application 50
presents the GPS position of collar 24 at display 34 on a map 58
along with the position of mobile telephone 14 so that the end user
can determine the relative position of collar 24 by looking at
display 34. Another example component is an accelerometer 60, which
detects movement of collar 24 and issues a point alert in the event
of a lack of movement under predetermined conditions, such as for a
predetermined time period, so that wireless communication module 52
communicates a point alert to mobile telephone 14. Another example
component is a camera 62, which captures still or moving images of
an area relative to collar 24 where a dog points and provides the
images to mobile telephone 14 through wireless communications
module 52. In one example embodiment, camera 62 is coupled to a dog
separately from collar 24 and communicates images to collar 24 with
a WPAN so that wireless communications module 52 can forward the
images to mobile telephone 14. Another example component is a
speaker 64, which provides audible commands, such as either
recorded voice or whistle tweets stored in memory of collar 24,
that a dog wearing collar 24 can hear. Speaker 24 may present
audible commands, either recorded voice or whistle tweets, provided
through a VoIP interface with mobile telephone 24 and communicated
through wireless communication module 52. For instance, an end user
can speak a command audibly captured at mobile telephone 14 and
played at speaker 64 or may press a button that issues an audible
command from memory of mobile telephone 14. Alternatively, speaker
64 may present audible commands, either recorded voice or whistle
tweets, in response to texts or other data that retrieves the
commands from a memory 66, such as a turn or a whoa command.
Another example component is a shock device 68 that applies a shock
to a dog that is wearing collar 24 in response to a command
received through wireless communication device 52. In alternative
embodiments, alternative types of positive or negative
reinforcements may be used, such as a clicker that issues clicks, a
squirter that squirts a fluid, a vibrator that vibrates, etc. . . .
.
[0038] Mobile telephone 14 includes WPAN communication that
supports interactions with local peripheral devices to give a
hunter hands-off interactions with collar 24. For example, a
wireless headset 70 includes an earpiece 72 to play audible sounds
in an end user's ears and a microphone 74 to capture commands by
the hunter. Headset 70 interacts with a Bluetooth or other types of
WPAN interfaces to communicate with mobile telephone 14. Another
example is a wireless handset 76 that has an armband or other
coupling device to make control buttons 80 accessible to a hunter
in a convenient location distal mobile telephone 14. For instance,
armband 78 couples to a hunter's wrist or gun to provide a collar
selector that selects one of plural collars 24 at which to output a
shock correction while the hunter's mobile telephone rests in a
pocket or safe location. As another example, handset 76 keeps a
body count of birds by species to help a hunter avoid violating a
game bag limit. As the hunter gets a bird, the hunter hits a button
associated with the species to allow training application 50 to
track the number of the species taken. When a limit is reached, the
hunter receives an audible warning in earpiece 72: "You have
reached your pheasant bag limit, don't shoot!" Handset 76 can also
be used to track other hunting information including location of
points or flushes, water sources, or other geographic features
which can be downloaded after the hunt for further analysis. In one
example embodiment, the sound of a gun shot picked up by a
microphone is recognized by training application 50 and
automatically marked. At an appropriate time after the gun shot,
the hunter is invited to speak a memo of what happened, which is
save in association with the location. The inquiry may also include
a request to update the body count. In one example embodiment, if
the hunter responds to a body count inquiry with "shutup," no
additions are made to the body count and the hunter is reminded
that he should attend church on Sundays instead of hunt.
[0039] An example of the mobile telephone dog training system 28 in
use follows, but is intended only as an example of how one
embodiment of the system may be used. A hunter plans a hunt and
stores the hunt boundary in a map 58 of memory 32 of mobile
telephone 14 that the hunter retrieves from the Internet. The
morning of the hunt, the hunter attaches first and second wireless
communication modules 52 to collar 24 and puts the collar on his
hunting dog. One wireless communication module 52 receives and
transmits WWAN communications and the other receives and transmits
802.11(n) WLAN communications. The dog is released to hunt and
disappears in cover. A moment later, accelerometer 60 detects that
the dog has stopped moving and gone on point. The WLAN
communication module 52 attempts to send a point alert to the
hunter but fails to receive a response from training application
50. In response, the WWAN wireless communications module sends a
text with the point alert to the hunter's telephone number. The
hunter's mobile telephone 14 intercepts the text on its way to the
cell tower and also receives the text message from the cell tower
and, in response, issues a point alert through a WPAN to an ear
piece 72 of wireless headset 70. The text includes the position of
the point included from a GPS component 56 of collar 24 so that
training application 50 provides the hunter with audible guidance
towards the point position. As the hunter approaches, training
application 50 initiates a video conference with camera 62 to
capture an image of the point through WLAN communication device 40.
If the point is on a skunk or snake, the hunter touches a control
button 80 on a handset 76 secured to his wrist with an armband 78
to issue a shock from shock device 68. In one embodiment, the image
includes infrared information to help distinguish varmints from
birds. If the point is on a bird, the hunter issues a "WHOA"
command from memory 66 or through a voice WLAN interface with
speaker 64, such as a VoIP interface. As the hunter approaches the
point position, a "flush" alert is issued to all mobile telephones
interfaced with the WLAN so that all hunters are prepared. For
instance, a training application running on each mobile phone
monitors the dog position and the hunter position with WLAN
communication and issues a flush alert when the hunter reaches a
predetermined location proximate the dog. After the flush, training
application 50 tracks the body count so that the hunter does not
exceed his allowed bag limit.
[0040] Referring now to FIG. 3, an adapter 82 is depicted to accept
a mobile telephone 14 for interacting with a dog collar 24. Adapter
82 forms an opening to accept mobile telephone 14 with a connector
84 aligned to couple with a port 86 so that a controller 88 can
interface with training application 50. Training application 50
provides information and instructions to controller 88 for sending
and receiving communications with transceiver 92 of adapter 82,
such as in a frequency band not available with the transceivers of
mobile telephone 14. Adapter 82 includes a battery 90 to boost the
charge life of mobile telephone 14 and a transceiver 92 to act as
an intermediary between mobile telephone 14 and collar 24.
Transceiver 92 offers improved radio communication range and
reliability in a number of different ways depending on the user
preference and the environment. For example, transceiver 92
provides increased range of communications from WLAN communications
device 40 by amplifying or boosting WLAN signals. Alternatively,
transceiver 92 communicates in a different radio band, such as a
lower frequency band having greater range than the WLAN frequency
band, with analog or digital signals to act as an intermediary
communication medium when out of WLAN communication range. In one
embodiment, training application 50 automatically detects the
adapter and selects the radio band and protocol to use for
communication based upon the range to collar 24. For instance,
training application 50 uses a WLAN interface when the GPS position
indicates collar 24 is within WLAN range and uses the intermediary
frequency of adapter 82 when the GPS position indicates collar 24
is out of WLAN range. Adapter 82 provides a more robust system for
hunters who desire to spend extra money on the extra feature;
however, for many infrequent hunters who use collar 24 for yard
work and occasional hunting trips, a WLAN range of 250M provides
adequate range and reliability. In one embodiment, adapter 82
includes a waterproof protective case to hold mobile telephone 14
in a secure manner. In one embodiment, a larger sized adapter works
for tablet type of devices that can include WWAN and WLAN
capabilities. In another alternative embodiment, adapter 82
includes a WPAN so that it can boost the range of a mobile
telephone 14 that is maintained separately and not inserted into
adapter 82. For example, a hunter can strap adapter 82 on his back
with an extended antenna for better range and the adapter
communicates through a WPAN with a mobile telephone in the hunter's
pocket as if the mobile telephone were coupled in adapter 82.
[0041] Referring now to FIG. 4, a flow diagram depicts a lock and
tone process for guiding a hunter to a dog on point. The process
begins at step 94 with detection of a point, such as with an
accelerometer or lack of change of GPS position. At step 96, an
audible point alarm is issued and an image of the point is
presented at the mobile telephone display. In one embodiment, the
alert and image is presented from the mobile telephone by a WPAN
communication to glasses that the hunter is wearing along with a
translucent map or a square or dot that indicates the location of
collar 24 relative to the lens of the glasses. The hunter is thus
able to see a map of the dog's position and an indication with a
red dot or "target box" of where the hunter should look to see the
dog through the glasses. At step 98, a determination is made of
whether the point is a valid point on a game bird species or an
invalid point, such as a point on a non-bird animal (a snake or
skunk). If not a valid point, the process goes to step 100 to issue
a correction, such as a shock stimulus, and returns to step 94. If
a valid point at step 98, the process continues to step 102 to
provide directions to the location of the point. If at step 104 a
determination is made that mobile telephone position has moved
further from the point position, the process continues to step 106
to issue a lower tone sound and then returns to step 102. If at
step 104 a determination is made that the mobile telephone position
has moved closer to the point position, the process continues to
step 108 to issue a higher tone sound and then returns to step 102.
Alternatively, directions at step 102 can present as computer
generated audible directions, such as turn left or right, or flush
in 10 yards.
[0042] Referring now to FIG. 5, a side view depicts an example
embodiment of adapter 82 for providing UHF and VHF frequencies and
that interacts with a wireless telephone 14 through a WPAN for
relaying information to and from a dog collar 14. Wireless
telephone 14 includes a training application as set forth above,
such as to present a GPS position at a display that is provided
from a collar 24 to an adapter 82 and then through a WPAN interface
to mobile telephone 14. Adapter 82 includes a Bluetooth module 110
to provide WPAN functionality for communication with a Bluetooth
transceiver of mobile telephone 14. A processor 112, such as a low
power ARM integrated circuit, executes instructions stored in a
flash memory 114 to perform adapter functions as set forth above
and below. In one embodiment, ARM processor 112 is an embedded
controller for Bluetooth module 110 that provides processing
support for other functions as described herein. A USB port 116
interfaces with processor 112 to allow programming of instructions
in memory 114, such as updates and patches; to retrieve information
from memory 114 to an external device, such as a history of GPS
positions tracked from collars 24; and to charge a battery of
adapter 82. In the example embodiment, adapter 82 has the footprint
of a pen or marker to fit in a pocket and a telescoping antenna 118
that slides over a housing 120 of adapter 82 to provide protection
when adapter 82 is not in use. For instance, an end user carries
adapter 82 in a shirt pocket like a pen until ready for use, and
then extends telescoping antenna 118 and places adapter 82 in a hat
band or other holder that maintains antenna 118 in an elevated
position for improved radio reception and transmission range. In
one embodiment, adapter 82 includes a GPS receiver of its own and
provides an adapter position to mobile telephone 14 so that mobile
telephone 14 can use the adapter position instead of or in
combination with a GPS position determined by a GPS receiver in the
mobile telephone.
[0043] Manual input buttons 122 are disposed on housing 120 of
adapter 82 to accept touch inputs from an end user and report the
touch inputs through Bluetooth module 110 to a mobile telephone 14
or dog collar 24, or through a wireless communication module 52 to
a dog collar 24. Manual input buttons 122 are manually programmable
by an end user to have varying functions that fit the user's
desires based upon operating conditions of adapter 82, mobile
telephone 14 and dog collar 24. For instance, an end user defines a
close-in display presentation for when collars 24 are in close
range, such as Bluetooth range, and a distal display presentation
for when collars 24 are distant, such as outside of Bluetooth
range. One of the manual input buttons 122 provides a hot-key that
an end user touches to select the close-in or distal display
presentation. As another example, an end user defines a first
display presentation showing a compass and a full screen map with
dog positions and a second display presentation with a half-screen
map with dog positions and a half-screen with statistics, such as
bag limits and kills for the day. The user prepares various display
presentations at mobile telephone 14 and mobile telephone 14
provides the selected presentations when a Bluetooth communication
from adapter 82 indicates an end user input at a button 122 to
hot-toggle between display presentations. Alternatively, a selected
presentation is made based upon a distance to collar 24, such as
the compass and full screen map if collar 24 is outside of
Bluetooth range and the half-screen with statistics if the collar
is within Bluetooth range.
[0044] In one example embodiment, wireless communication module 52
disposed in adapter 82 includes a 900 MHz transceiver to provide
moderate range of a mile or less and a 150 MHz transceiver to
provide increase range of greater than a mile. In an alternative
embodiment, a Silicon Labs EZRadio Si446X transceiver provides a
selectable range of frequencies from 119 MHz to 1 GHz and transmits
at a frequency set by mobile telephone 14 based in part upon
distance to a dog collar 24. For instance, the transceiver steps
between 900 MHz and 150 MHz based upon range to collar 24, signal
strength from collar 24 and interference received from other
transceivers. The use of either Bluetooth, 900 MHz, 150 MHz or
other frequency signals to communicate with dog collar 24 is
selected based upon logic running on processor 112 or logic running
on mobile telephone 14 that provides control instructions through
Bluetooth communications to processor 112. In one embodiment, an
end user preselects frequencies at mobile telephone 14 for use by
adapter 82 at various ranges so that plural systems operating in
the same area have frequency ranges for use that are away from each
other to avoid interference. For instance, one mobile telephone
adapter 82 uses 850 MHz with range of less than one-half mile and
145 MHz with range of greater than one-half mile; another nearby
mobile telephone phone adapter uses 900 MHz with range of less than
one-half a mile and 150 MHz with range of greater than one-half a
mile. A mobile telephone associated with each adapter communicates
with each other in an ad hoc peer-to-peer 802.11(n) network to
maintain frequency separation by defining for each other the
frequency assigned for use by each mobile telephone's adapter.
Alternatively, the mobile telephones 14 communicate with an ad hoc
peer-to-peer network to establish the use of common frequencies in
different time slots to avoid interference yet allow monitoring of
each other's collars. In one embodiment, frequencies and time slots
are determined beforehand and separately stored in each mobile
telephone with coordination provided by a computer application. For
example, an XML file stores time slots, frequencies, collar
identifiers and map coordinates for plural mobile telephones 14 so
that each mobile telephone can download and apply the information
at the time of a hunt. For instance, a website stores plural XML
files that end users can download to apply desired configurations,
such as based on the number of mobile telephones and collars, to
have a preconfigured hunt with assigned frequencies and time slots
for each collar and mobile telephone. On the start of a hunt, the
mobile telephones distribute the preconfigured assignments to the
collars with Bluetooth communications.
[0045] Referring now to FIG. 6, an example is depicted of a mobile
telephone 14 interacting with an adapter 82 and a collar 24 through
plural radio frequencies, such as under management of a training
application as set forth above. Upon initial setup, mobile
telephone 14 pairs with Bluetooth to both adapter 82 and dog collar
24. Mobile telephone 14 retrieves identifiers from adapter 82 and
dog collar 24 so that the devices are automatically configured to
communicate with each other using the wireless communication module
52, such as a packet header or other identifier to link adapter 82
with collar 24 and a frequency assignment for both devices to use
in mid and low frequency ranges. In one alternative embodiment,
initial configuration may be performed with a near field
communication (NFC) device in mobile telephone 14, adapter 82 and
collar 24. Initially, dog collar 24 provides GPS information to
both adapter 82 and mobile telephone 14 with the Bluetooth pairing.
Bluetooth communications consume minimal power and provide a range
of around 10M so that during the initial phase of a hunt while the
dogs are in close to mobile telephone 14, battery consumption of
dog collars 24 is reduced relative to communications in other
frequencies. In one alternative embodiment, GPS positions are not
provided from collar 24 to mobile telephone 14 when Bluetooth
pairing exists since the distance is small. In another embodiment,
with the exception of an initial test to ensure operability of
adapter 82, mobile telephone 14 commands adapter 82 through a
Bluetooth communication to remain idle while mobile telephone 14
has Bluetooth pairing and communication with dog collar 24.
Although Bluetooth is rated as having a range of 10M, the
communications take place at 2.4 GHz, the same as a WLAN 802.11 (b
or g) communication, and thus may work at greater effective ranges
to provide GPS coordinates from dog collar 24 directly to mobile
telephone 14 when a dog is hunting close in or when a hunter
approaches a dog, such as a dog on point. Further, in one example
embodiment, the Bluetooth signal may be amplified from dog collar
24 to increase Bluetooth range to mobile telephone 14, such as by
providing a higher strength signal as distance increases based upon
GPS coordinates analyzed at mobile telephone 14 or collar 24.
[0046] Once dog collar 24 reaches the limit of Bluetooth
communication directly with mobile telephone 14, such as when a dog
ranges out to start hunting, mobile telephone 14 initiates adapter
82 with a Bluetooth communication to adapter 82 so that a
mid-frequency may be used to collar 24, such as communication with
a 900 MHz radio. Adapter 82 initiates communication with dog collar
24 through the mid-frequency to retrieve GPS coordinates from dog
collar 24 and provides the GPS coordinates to mobile telephone 14
through Bluetooth communications. If the signal strength of the
mid-frequency transceiver communications between dog collar 24 and
adapter 82 becomes weak or the GPS coordinates of collar 24
relative to adapter 82 indicate a range at the outside of the
mid-frequency range, then mobile telephone 14 initiates the use of
a low-frequency, such as 150 MHZ, by adapter 82 to dog collar 24.
Adapter 82 sends a frequency change command in the mid-frequency
range to dog collar 24 so that dog collar 24 can reset the
frequency with a matching transceiver. As range decreases between
adapter 82 and dog collar 24, such as when a hunter approaches a
dog on point, mobile telephone 14 returns adapter 82 and collar 24
to the use of the mid-frequency followed by the Bluetooth
communications for obtaining GPS coordinates from dog collar 24. An
advantage of using a mid-frequency is that it tends to consume less
power and communicate more information than a lower frequency. In
addition, mid and low frequencies have different characteristics so
that one may work better than the other under different operating
conditions, such as caused by weather, water, terrain, cover, etc.
. . . . Further, in areas where a number of hunters are using mid
or low frequencies, the availability of a second (or other tunable)
frequency band will improve system reliability by decreasing
interference.
[0047] Referring now to FIG. 7, a flow diagram depicts a process
for determining a frequency for communication with a dog collar 24.
For example, the process is provided by a training application
executing on a mobile telephone 14 as set forth above. The process
starts at step 124 with a pairing of Bluetooth transceivers located
in mobile telephone 14, adapter 82 and collar 24. During pairing,
configuration information is provided between the devices to enable
communication of GPS position from collar 24 to adapter 82 and then
to mobile telephone 14 for presentation at a display of mobile
telephone 14. For example, an identifier for each device is
provided to the other devices so that mobile telephone 14 can track
GPS positions for the desired collar or collars 24. During pairing
at step 124, a test may be performed to confirm operation of
wireless communication module 52 for communication between adapter
82 and collar 24 to ensure that the desired frequencies are
operational, such as frequencies selected for use by the hunter
that day. Once pairing is complete, Bluetooth communications are
maintained between mobile telephone 14, adapter 82 and collar 24
while Bluetooth-compatible ranges are maintained. Maintaining
communication by Bluetooth through the early part of the hunt
reduces power consumption by adapter 82 and allows automated
activation of adapter 82 once pairing with collar 24 is lost or
when Bluetooth communication of GPS coordinates indicates a
threshold range, such as greater than 10M. Hunters thus do not have
to manually place systems on and standby between hunts, and power
is preserved by avoiding mid and low frequency transmissions when
not necessary. At step 126, a determination is made whether
Bluetooth pairing is maintained with dog collar 24 by adapter 82 or
mobile telephone 14. If yes, the process returns to step 124 to
continue monitoring GPS coordinates by Bluetooth communications. If
no, the process continues to step 128 to activate adapter 82. In
one example embodiment, transition from Bluetooth communication to
adapter communication and back to Bluetooth communication may be
aided by applying GPS coordinates of collar 24 compared to GPS
coordinates of mobile telephone 14 to determine when Bluetooth
range has reached a likely limit. When accurate range information
is available so that adapter 82 uses wireless communication module
52 to communicate with dog collar 24, the Bluetooth transceiver or
collar 24 may be idled to stop transmitting, thus saving additional
power while the range between mobile telephone 14 and dog collar 24
is too great to communicate with Bluetooth. Once GPS coordinates of
collar 24 and mobile telephone 14 indicate a Bluetooth compatible
range as indicated by communications between adapter 82 and collar
24, Bluetooth transmissions may resume and transceiver 52 may be
powered off.
[0048] At step 128, a determination is made of the frequency that
adapter 82 will use to establish communications with dog collar 24.
In one embodiment, the frequency is determined in mobile telephone
14 and sent by a Bluetooth communication to adapter 82. For
example, upon initially leaving Bluetooth range, a mid-frequency is
selected for adapter 82. As range between adapter 82 and collar 24
increases, a transition to a low-frequency is performed based upon
a number of factors, including: distance determined from GPS
coordinates, signal strength, vector (speed and direction) of
collar relative to frequency range capabilities, interference from
other radios, etc. . . . . Similarly, as range between adapter 82
and collar 24 decreases, a transition to a mid-frequency from a low
frequency is performed. In one alternative embodiment,
determination of the frequency for adapter 82 may be made with
logic operating on adapter 82. For instance, when mutual
communication between adapter 82 and collar 24 has not taken place
for a predetermined time period, a recovery frequency is selected
to attempt to establish mutual communication. In one embodiment,
the timing of the recovery frequency attempt is based upon GPS
clock signals so that power at collar 24 and adapter 82 is not
needlessly wasted attempting to re-establish communications. At
step 130, communications are performed at the determined frequency.
At step 132, a determination is made of whether Bluetooth
communications are re-established. If so, the process returns to
step 126. If not, the process returns to step 128 to re-verify the
frequency for use by adapter 82 to communicate with collar 24. When
a new frequency is selected, the frequency is passed to collar 24
with the existing frequency so that communications are
re-established on the new frequency.
[0049] Referring now to FIG. 8, an example embodiment is depicted
of a system that tracks multiple dog collars 24 at one or more
mobile telephones 14 using one or more adapters 82. Management of
the multiple dog collars is performed, for example, by a training
application running on one or more mobile telephones 14 as set
forth above. In one example embodiment, the training application
distributes logic and communication parameters to adapter 82 and
collar 24. If one or more collars 24 are within Bluetooth range of
each other, then the collar 24 having the most battery power is
selected to use mid or low frequency communication with adapter 82
while the other collars 24 have their transceivers in sleep mode to
save power. The selected collar 24 retrieves GPS positions from the
dog collars within Bluetooth range and sends the GPS positions to
adapter 82 so that only one collar 24 drains its battery with mid
or low frequency communications. Alternatively, only one GPS
position is sent from the selected dog collar along with the
identifiers of all collars 24 that are in Bluetooth range so that
mobile telephone 14 can track each identifier as in the same
proximate location. In alternative embodiments, GPS positions and
collar identifiers may be relayed using mid and/or low frequency
transmissions between various collars 24 and adapters 82 so that
each mobile telephone 14 can track all dog collars 24. In one
example situation, if a dog is on point and another dog is honoring
the point, GPS position information is sent from only one dog until
flush is approached by a hunter, such as at issuance of a flush
alert, at which time each collar 24 sends GPS information to
protect the safety of each dog. For instance, if a hunter is
positioned to shoot in the direction of a dog at flush, a warning
may issue to an earpiece or with a phone ring to help prevent harm
to the dog: "Don't shoot Jewel located ten meters north of your
current position."
[0050] Referring now to FIG. 9, a variety of examples are depicted
that provide improved battery life and reduced radio interference
in hunting situations with multiple dogs and hunters. For instance,
a training application executing on a mobile telephone 14 as set
forth above manages battery life and transmission interference by
managing operation of adapter 82 and collar 24. Transmissions from
collar 24 consume power from an internal battery so that more
frequent transmissions result in shorter charge life for a given
size battery. By reducing transmissions from collar 24, battery
charge is conserved so that a smaller battery will support a collar
for a given operating time. Further, reduced numbers of
transmissions result in less bandwidth consumption so that less
interference occurs in situations where multiple collars 24 and or
adapters 82 are deployed. Less interference generally means that
transmission attempts have a greater chance of success, thus
further reducing the need for transmissions, such as repeated
transmissions of the same data. To provide reduced transmissions,
collar 24 and adapter 82 use logic to divide transmissions from
each of plural collars 24 and adapters 82 into plural time slots.
In one embodiment, a GPS clock is used as a reference point from
which time slots are defined so that an internal clock on each
device can precisely track its time slot for transmitting and
receiving information relative to other devices. In addition, logic
on collar 24 analyzes GPS position data and accelerometer data
locally at collar 24 or in combination with mobile telephone 14 to
limit transmissions where changes in position are relatively
insubstantial. For instance, in an example embodiment, at periodic
time slots, collar 24 only transmits if GPS data shows a change in
position of greater than a minimum amount, such as 5M, or if a
change in acceleration indicates a change in position relative to
what the mobile telephone 14 monitoring collar 24 would expect over
the time. Accurate position data is maintained at the mobile phone
14 by providing updates at minimum intervals, such as every minute.
Accurate estimated positions are maintained at mobile phone 14 by
applying accelerometer and orientation information (such as a
velocity vector) provided from collar 24 (or alternatively GPS
position data from collar 24 analyzed by mobile telephone 14 for
change over time to estimate a velocity vector) to estimate
positions with a virtual inertial navigation system (INS) between
collar transmissions.
[0051] In the example embodiment depicted by FIG. 9, a first set of
collars 24 labeled (1-n) is controlled by a first adapter 82 and
first mobile telephone 14. A second set of collars 24 labeled (a-n)
is controlled by a second adapter 82 and a second mobile telephone
14. The first and second mobile telephones 14 establish an ad hoc
network with peer-to-peer communications using 802.11(n) to define
time slot and frequency assignments for each adapter 82 to
communicate with each set of collars 24. The first adapter 82 has a
time slots t1 though tn with each time slot having an adequate
length for a collar 24 to communicate GPS, accelerometer and/or
other desired data. The time slots are defined relative to a GPS
clock signal and tracked with an internal clock at each device,
such as with a processor that controls a Bluetooth transceiver. The
GPS clock signal also provides synchronization for communications
between mobile telephones 14 in support of the ad hoc network. The
time slots t1 through tn are sequentially defined so that adapter
82 activates its transceiver from sleep to listen across all time
slots and then sleeps until the start of the next time slot period.
Time slot periods may occur at regular intervals and/or at times
defined relative to a GPS clock so that collars 24 know when to
transmit to adapter 82. Collars 24 transmit in an assigned time
slot if position updates have at least a minimum change or if a
maximum time has elapsed since a previous transmission; otherwise,
collars 24 keep their transceivers in a sleep mode to reduce power
consumption. In one embodiment, collars 24 listen for a
transmission from a collar in a previous time slot and initiate
communication when the previous collar completes communication. In
another embodiment, a collar 24 sleeps its transceiver 52 to reduce
power consumption except during a time slot assigned to the collar.
As an example each time slot t1 through tn lasts for one second
with a one second idle time between each time slot until tn plus
one second, then adapter 82 idles for 15 seconds from t1 based upon
a GPS clock signal, after which adapter 82 awakens to repeat
listening. Collar 24 remains idle up to five minutes unless a
change in position or acceleration is detected, in which case a
transmission is made during an assigned time slot. Adapter 82 has
frequent "listening" times available to accept communication in a
prompt manner when needed, such as at detection of a point, so that
a collar 24 can communicate in a time slot when needed without an
excessive delay. When a change in position or acceleration is
detected, or five minutes has elapsed since the last collar
transmission, collar 24 then transmits during a time slot assigned
to it, such as based upon a reference to a GPS clock signal
provided by a GPS transmission shared by a GPS receiver of collar
24 and mobile telephone 14. In one example embodiment, a collar 24
powers up its transceiver at predetermined "listen" times to
receive position requests from an adapter 82. If adapter 82
requests a position update during a listening time, collar 24
responds with a position; otherwise, collar 24 saves power by
avoiding unnecessary transmissions.
[0052] After the first mobile telephone 14 adapter 82 completes
listening in its time slots, first adapter 82 may sleep its
transceiver or, alternatively, may listen during the time slots
assigned to the second adapter 82 so that first mobile telephone 14
can independently track collars 24 assigned to second mobile
telephone 14 adapter 82. Similarly, second mobile telephone 14 can
independently track collars 24 assigned to first mobile telephone
14. If mobile telephones 14 have too great a distance to
communicate between each other with 802.11(n) or Bluetooth, then
communications may take place between mobile telephones 14 through
mid or low frequency transmission through adapters 82. If different
frequencies are assigned to each adapter 82 for its collars 24,
then an adapter 82 changes to the frequency of the other adapter 82
when listening for collars 24 in time slots managed by the other
adapter 82. The overall effect of the use of time slots is that
adapters 82 listen for transmissions from collars 24 at more
frequent intervals than collars 24 transmit information, which may
increase power consumption at adapters 82 relative to collars 24
but tends to decrease power consumption at collars 24 so that a
smaller battery may be used at collar 24 to allow a smaller collar
footprint than would be possible if collar 24 simply transmitted at
regular intervals. Additional power savings may be achieved by
adjusting the power used to transmit from collar 24. For instance,
adapter 82 provides feedback to collar 24 of the signal strength
received at adapter 82 and/or the distance between adapter 82 and
collar 24. Collar 24 applies the feedback to adjust transmitter
power settings, such as by reducing transmitter power when adapter
82 reports receiving a strong signal at a short distance or
increasing transmitter power when the signal received by adapter 82
falls below a threshold.
[0053] Referring now to FIG. 10, an example embodiment depicts a
collar 24 that applies logic to selectively communicate position
information in order to reduce the number of transmissions from
collar 24 and thus save power. For instance, a training application
running on a mobile telephone provides logic to a collar 24 for
execution on collar processor 112 to manage transmissions from
collar 24 to an adapter 82. Accelerometer 60 includes gyroscopes to
provide measurements of accelerations and the orientation of
accelerations at collar 24, such as with a three axis MEMS-type
device that has three gyroscopes aligned with three accelerometers.
In one example embodiment, a lack of acceleration indicates a dog
at point so that collar 24 makes less frequent position
transmissions to save power since the collar's position does not
change. If a lack of accelerations is replaced by new detected
accelerations that indicate a point has ended, then transmissions
are re-initiated to update mobile telephone 14 regarding
position.
[0054] In one example embodiment, accelerometer 60 provides
acceleration and orientation information to an integrator 134,
which analyzes the acceleration and orientation information to
determine a velocity vector at collar 24. Integrator 134 may
execute as software on collar 24 or as a specialized hardware
component interfaced with accelerometer 60. Integrator 134 may
simplify generation of a velocity vector based upon the type of
motion being tracked. For example, a running dog will have repeated
pattern of motion that includes outlier accelerations when the
overall running vector changes, such as with a turn or change in
speed. Integrator 134 in one embodiment uses averaging of
accelerations to identify outliers that allow generation of an
average velocity vector for a given time period. In another example
embodiment, when tracking motion of a dog or other moving animal, a
constant acceleration of gravity alone indicates zero average
velocity. In contrast, when tracking motion of an inanimate object,
such as car, a constant acceleration of gravity alone may indicate
a constant speed.
[0055] A GPS signal evaluator 136 analyzes the velocity vector (or
alternatively the acceleration and orientation information itself)
and GPS positions from GPS 56 to determine whether to transmit GPS
or velocity vector (or raw acceleration/orientation information)
information from collar 24 to adapter 82 or to maintain a sleep
mode with the collar transceiver. If, for instance, a velocity
vector associated with collar 24 remains relatively constant, then
less frequent position transmissions are provided to mobile
telephone 14 since mobile telephone 14 can apply the velocity
vector to estimate collar position with relative accuracy. The
velocity vector used by mobile telephone 14 to estimate position
may be provided from collar 24, may be determined at mobile
telephone 14 from acceleration and orientation information provided
from collar 24, or may be estimated by mobile telephone 14 from GPS
positions provided by collar 24 over time. If, in contrast, a
velocity vector associated with collar 24 changes by a
predetermined amount, then more frequent position transmissions are
provided to mobile telephone 14, including updated velocity vector
information. As another example, if a GPS signal becomes weak so
that GPS position is unreliable, such as may happen under dense
foliage, GPS signal evaluator withholds GPS position information
and sends more frequent velocity vector (or alternatively
acceleration and orientation information) to mobile telephone 14 so
that a virtual inertial navigation system (INS) 138 executing on
mobile telephone 14 can track collar position with INS logic based
upon accelerometer and gyroscope orientation measurements taken at
collar 24 and transmitted to mobile telephone 14, such as in the
form of a velocity vector. In one embodiment, GPS signal evaluator
136 applies an end user accuracy/power preference setting to
determine how often to transmit position information; a higher
accuracy preference with more frequent transmissions will consume
increased battery charge resulting in reduced battery life.
[0056] Referring now to FIG. 11, a flow chart depicts one example
of logic for determining when to communicate position information
from a collar 24. The process starts at step 140 with a
determination of whether the collar 24 is on point or otherwise
immobile. If yes, a point alert issues upon initial determination
of the point and the process continues to step 142 to determine if
a minute has passed since the last transmission from collar 24. If
a minute has not passed, the process returns to step 140. If a
minute has passed at step 142, then a position transmission is made
at step 148 and the process returns to step 140. If the point
determination at step 140 is no, the process continues to step 144
to determine if a velocity vector change has occurred based upon
sensed accelerations and orientations. If a velocity vector change
has not occurred, the process continues to step 142 to determine
the last transmission as set forth above. If a velocity vector
change has occurred, the process continues to step 146 to determine
if a measured GPS position has changed by greater than a
predetermined amount, such as 10M. If not, the process continues to
step 142 to determine whether to make a transmission as set forth
above. If yes, the process continues to step 148 to make a
transmission. In one example embodiment, transmissions are made
during defined time slots during which adapter 82 is awake to
receive the transmissions, such as every 10 seconds based upon a
GPS clock reference that improves accuracy in defining the time
slot. In one alternative embodiment detection of a vector change
can initiate a transmission at step 148 even where GPS position has
not changed beyond a minimum amount. This provides positive updates
based upon activity associated with the dog that may indicate a
chase or an inaccurate GPS position signal. In one alternative
embodiment, position information is transmitted from collar 24
based upon a change in position of greater than a threshold amount
from the last transmitted position, such as every time the collar
moves 10M or greater from a last transmitted position. This updates
positions when positions change and saves power by avoiding
transmissions from a collar 24 when a position has not changed
enough to warrant an update to a training application.
[0057] FIG. 12 depicts one example of a modular collar 24 adapted
for use with a shock device 68, such as to enforce a GPS fence
boundary 12. Collar 24 has a first portion 150 that contains
processing components for managing position data and performing
radio transmissions, and a second portion 152 for providing power
with a battery 154. In the example embodiment, a shock device is
included with the second portion 152, however, in alternative
embodiments second portion 152 provides a removable battery 154
without a shock device that can have a smaller footprint where
power is only needed for first portion 150 and not needed for a
shock device 68. First portion 150 interfaces with second portion
152 with opposing mini-USB ports 156 that allow battery 154 to
power first portion 152 and allow a processor of first portion 152
to control shock device 68. Using USB ports 156 for interfacing
first portion 152 with second portion 154 conveniently allows logic
and charging interfaces with each portion by USB devices, such as a
laptop computer that charges battery 154 and accesses flash memory
66 of first portion 150. First portion 152 includes a Bluetooth
module 110 and ARM processor 112 that controls Bluetooth
operations. A wireless communication module 52 interfaces with
processor 112 to communicate with adapter 82 using mid and/or low
frequency signals as described above. An external computer
interfaced through a USB port 156 of first portion 150 can store
coordinates of boundary 12 for access by processor 112 so that
processor 112 can issue a shock by shock device 68 if collar 24
approaches a boundary. Alternatively, Bluetooth communications from
an external computer can store the boundary coordinates in flash
memory 66.
[0058] Advantageously, collar 24 maintains minimal power
consumption while monitoring position with GPS 56 because no
transmissions are made by wireless communication module 52 as long
as collar 24 remains within the GPS coordinates boundary 12 stored
in flash memory 66. If collar 24 approaches a boundary 12 defined
by GPS coordinates in flash memory 66, then shock device 68 issues
a stimulation to motivate the dog to return to the boundary. In one
embodiment, a voice command issues from collar 12, such as a whoa
command stored in flash memory 66 and played at a speaker of collar
12, so that the dog stops moving. Stimulation issues at shock
device 68 if the dog fails to whoa. Along with the whoa command,
the processor 112 initiates communication through wireless
communication module 52 to issue a warning to an end user that the
dog has approached and/or breached boundary 12. If collar 24 is
within extended Bluetooth range, the warning may issue with a
Bluetooth or an 802.11(b, g or n) signal to a computer device or
mobile telephone 14 of the end user. Alternatively, wireless
communication module 52 remains powered down until a boundary 12 is
approached or breached and then transmits through low or mid
frequency ranges as described above to allow an end user to locate
collar 24 with the GPS position received by an adapter 82 and
forwarded to a mobile telephone 14 or other computing device. In
one embodiment, adapter 82 stores GPS positions and acceleration
information so that an end user can recall at a later time the
direction taken by collar 24. In another embodiment, once a collar
24 breaches a boundary 12, a recovery signal with the GPS position
is issued at regular time intervals from wireless communication
module 52 of collar 24 based upon a GPS time signal or other clock
to synchronize transmission of signals from collar 24 with
reception of signals by adapter 82. For instance, collar 24 issues
a signal at 15 second intervals on four different frequencies in
sequential order each minute to ensure that interference does not
impede signal transmission. Adapter 82 knows the frequency to
listen to on each 15 second interval based upon a GPS clock signal
available to both adapter 82 and collar 24 that ensures
synchronization with an internal clock, such as a clock supported
by processor 112. In an alternative embodiment, collar 24 listens
at the 15 second intervals without transmitting unless a
transmission is detected from adapter 82 that commands a
transmission of position information from collar 24; this allows
collar 24 to preserve battery charge for a longer time period.
Other power savings techniques may be used at collar 24 as
described above, such as only transmitting a position if the
position changes by more than a threshold from the most recent
position transmitted by collar 24 and received by an adapter 82,
such as by sending a confirmation of position reception from
adapter 82 to collar 24. In summary, collar 24 maintains a low
power mode while a dog remains in boundary 12 by executing
instructions on processor 112 without communication with external
devices and then initiates a transceiver when a dog breaches the
boundary 12 to provide a warning and position information to an
adapter 82 for presentation at a mobile telephone 14 or other
computing device. An end user is able to monitor a dog's position
for lengthy time periods with minimal battery discharge by avoiding
communications until position information is needed because the dog
has left a proscribed area.
[0059] In various embodiments, various portions of the collar,
adapter, training application and virtual INS may be used in
different ways, alone and in combination with each other. As an
example, although collar 24 is presented in the context of a dog
collar, similar use is made with monitoring of children, such as by
attaching a collar 24 to a child as a wrist bracelet, ankle
bracelet or necklace. A parent can set parameters to issue
warnings, for example, if a child leaves a park, school, shopping
center, athletic event, etc. . . . . A parent can monitor for
sudden accelerations that might indicate an injury to a child, or a
velocity vector towards a busy street, and obtain immediate oral
warnings in an earpiece having a Bluetooth interface with a mobile
telephone 14. For instance, a high g-force detected by an
accelerometer triggers an "injury" alert for the parent similar to
the point alert for a dog. Monitoring by adapter 82 provides an
inexpensive alternative to tracking devices that require cell phone
service. A virtual INS operating on a mobile telephone based upon
acceleration and orientation information provided from a collar
allows a parent to monitor a child's position during indoor
activities where GPS reception is sometimes intermittent. Power
savings techniques set forth above allow a collar 24 to have a
small footprint that a child can wear a collar with relative
comfort and minimal interference with the child's activities.
Further, a speaker and microphone on the collar can provide the
parent with immediate voice access and the ability to listen to the
child's environment when appropriate by interfacing through adapter
82 or an ad hoc peer-to-peer communication with 802.11(b, g or n).
As another example, adapter 82 interfaces with any device that
receives WPAN communications, such as Bluetooth, including laptops,
tablets or desktop systems. For example, a parent wearing Google
Glass obtains a GPS position of a collar 24 from adapter 82 with a
Bluetooth communication and can present at the glass a box over the
position of the child so the parent can quickly obtain a visual of
the child. Virtual INS may track inanimate objects, such as
packages or items subject to theft and can issue a theft alert in
the event of a sudden acceleration. Mobile telephone 14 may have
adapter 82 integrated within its housing to provide a mobile
telephone 14 with integrated adapter functionality. Alternatively,
mobile telephone 14 may alter operation of existing hardware, such
as firmware that executes 802.11(b, g or n) or Bluetooth
communication, to provide communications at various tunable
frequencies in the place of an adapter 82. Other alterations to the
described dog collar, adapter, mobile telephone embodiment are
contemplated as desired to track items as desired by an end
user.
[0060] Although the present invention has been described in detail,
it should be understood that various changes, substitutions and
alterations can be made hereto without departing from the spirit
and scope of the invention as defined by the appended claims.
