DIRECTED SOUND TRANSMISSION SYSTEMS AND METHODS USING POSITION
LOCATION
Abstract
Systems and methods herein provide directed sound to venues,
including a queue line and locations offering multiple viewing
devices with different audio streams. Directed sound can be sent to
various locations in the queue line to reach specific individuals,
positions in the queue line, etc. A queue rate may be used to
determine current locations in the queue line. The directed
transmission of sound waves can provide the directed sound through
modulation of the sound on an ultrasonic carrier. In connection
with directing sound to a specific location in a venue, one or more
individuals can be tracked according to an indoor positioning
system to send a sound message using a modulated ultrasonic
carrier.

SOUND TRANSMISSION SYSTEMS AND METHODS.

incorporated by reference herein: U.S. patent application Ser. No.
17/364,716; filed Jun. 30, 2021; entitled DIRECTED SOUND
TRANSMISSION SYSTEMS AND METHODS.
BACKGROUND
Field
[0003] Various embodiments disclosed herein relate to speakers.
Certain embodiments relate to parametric speakers.
Description of Related Art
[0004] Communication in noisy environments has always been a
challenge. Getting someone's attention while standing in line or in
conjunction with waiting in line may require shouting to get the
person's attention. In an ever-evolving world, besides the noise
present in an environment, conveying a message can also result in a
competition for time. Particularly for advertising, messages
directed at people can sometimes best be sent when they are waiting
for something or have periods of downtime. For instance,
individuals standing in line can represent a captive audience for
receiving messages. So too are patrons of a bar or restaurant.
[0005] Loudness is measured in a unit defined as decibels (dB).
Noises that are above 85 dB may cause hearing loss over time by
damaging ear fibers. The ear can repair itself if exposed to noise
below a certain regeneration threshold. Still, once permanent
damage occurs and one's hearing is gone, ear fibers cannot be
fixed, nor can a person regain their hearing. Some examples that
employ a safe hearing range include whispering and normal
conversations around 30 dB and 60-80 dB, respectively. Unsafe zones
include sporting events, rock concerts, and fireworks, around
94-110 dB, 95-115 dB, and 140-160 dB, respectively. Headphones fall
into the range of 96-110 dB, placing them in the unsafe region. The
ear should only be exposed to an intensity of 97 dB for about 3
hours per day, 105 dB for about 1 hour per day, or 110 dB for 30
minutes per day before causing ear damage.
[0006] As described, damage to the ear may occur when headphones
deliver unsafe sound levels directly to the ear canal. This damage
is directly related to how much that sound makes your eardrum
vibrate. When using speakers, sound waves have to travel a few feet
before reaching the listener's ears. This distance allows some of
the higher frequency waves to attenuate. With headphones, the
eardrum will be excited by all frequencies without attenuation, so
headphones can be more damaging than speakers at the same volume.
Additionally, many people are trying to produce acoustic isolation
when using headphones, which requires higher volumes to drown out
ambient noise. For this reason, headphone audio levels should be
chosen cautiously so as not to cause permanent ear damage and
hearing loss.
[0007] In addition to hearing loss, headphones can cause a ringing
in one or both ears, known as tinnitus, pain in the ear, or
eardrum. Other physical effects from headphone use include ear
infections, characterized by swelling, reddening, and discharge in
the ear canal, itching pain, and feelings of tenderness or fullness
in the ear. Impacted wax (i.e., wax buildup) and aural hygiene
problems may also result from headphone use. They can create a
potential for bacteria to form in the ear canal due to increases in
temperature and humidity of the ear canal. As a consequence of the
above, communications involving headphones are far from ideal.
[0008] Parametric speakers provide directed sound over smaller
wavelengths than most conventional systems, enabling a higher
degree of directionality than other systems. Sound can be focused
at a high intensity for receipt by a specific receiver.
Nevertheless, harmful noise levels, as described above, are a
constant source of concern. Further, hearing for an individual may
be age-dependent, especially as one becomes older. Generally, there
may be sound loss of hearing at higher frequencies with increased
age. Further, high frequencies can damage hearing, especially at
high-intensity levels.
[0009] There is a need to implement parametric speaker technology
and methods that better facilitate the safe conveyance of messaging
over and above that presently used.
SUMMARY
[0010] In some embodiments, a focused beam directional speaker
system is provided, which includes a modulator configured to
produce an ultrasonic modulated carrier signal by modulating an
ultrasonic carrier signal with the audio signal. In some
embodiments, the system comprises a queue rate processor configured
to calculate a queue rate and determine a target's location in a
queue based on the queue rate. The system may include at least one
ultrasonic focused beam directional speaker configured to send,
based on the queue rate, to a target in a queue area, an ultrasonic
pressure wave, representative of the ultrasonic modulated carrier
signal, through a transmission medium. In some embodiments, the
ultrasonic modulated carrier signal demodulates in connection with
the ultrasonic pressure wave reaching the target.
[0011] In some embodiments, the focused beam directional speaker
system comprises a translation engine including a translation
processor coupled to the ultrasonic focused beam directional
speaker.
[0012] The focused beam directional speaker system may include one
or more directional microphones coupled to the translation engine
in some embodiments.
[0013] In some embodiments, the focused beam directional speaker
system includes a video processor configured to receive video
samples of the queue area. The video processor may be coupled to
the queue rate processor.
[0014] Even still, in some embodiments, the at least one ultrasonic
focused beam directional speaker is further configured to send the
ultrasonic pressure wave, based on the queue rate, in conjunction
with video information processed by the video processor, to the
target in the queue area.
[0015] The disclosure also includes methods of providing focused
beam directional sound to predetermined locations in a queue area.
In some embodiments, the method includes calculating a queue rate;
sampling sound by taking one or more sound samples from at least
one location within a queue area; identifying a language, when
present, inherent within audio information received from the one or
more sound samples; producing an audio content signal for a target,
in the queue area, in the language; generating a modulated
ultrasonic signal, for the target, in the queue area, by modulating
an ultrasonic carrier with the audio content signal for the target
in the queue area; and transmitting, to a current location,
determined from the queue rate, of the target in the queue area, an
ultrasonic pressure wave, representative of the modulated
ultrasonic signal, through a transmission medium.
[0016] In some embodiments, the method includes calculating the
queue rate in conjunction with using video samples of the queue
area. The sampling may be accomplished in connection with using one
or more directional microphones aimed at the predetermined
locations within the queue area.
[0017] In some embodiments, the method includes modulating the one
or more audio signals with an ultrasonic carrier signal to produce
one or more modulated ultrasonic carrier signals; sending one or
more ultrasonic pressure waves, through a transmission medium,
representative of the one or more modulated ultrasonic carrier
signals, to one or more target locations, as selected therefor, in
a listening environment, wherein in connection with the one or more
ultrasonic pressure waves reaching the one or more target
locations, the one or more modulated ultrasonic carrier signals
demodulate.
[0018] In some embodiments, the listening environment is a venue
having a plurality of audio and video monitors distributed within
the venue. The one or more target locations within the listening
environment may include a seating location within the listening
environment.
[0019] In some embodiments, the system disclosed herein may be
integrated into other digital systems/hardware. For instance, a
restaurant chain such as Chili's.RTM. has tablets on tables for
ordering. The system described herein may be integrated for use
with the Chili's.RTM. ordering system.
[0020] In some embodiments, the method further includes producing
white Gaussian noise; modulating the one or more ultrasonic
pressure waves by the Gaussian noise to produce one or more
modulated noise signals; and transmitting, to an area section in
the listening environment, the one or more modulated noise signals
through the transmission medium.
[0021] In some embodiments, the method further includes sampling
sound by taking one or more sound samples in the listening
environment; determining noise in the listening environment;
producing a noise signal from the noise; producing an
inverted-noise signal by inverting the noise signal; generating an
inverted-noise modulated ultrasonic signal by modulating an
ultrasonic carrier with the inverted-noise signal; and
transmitting, to one or more target locations in the listening
environment, an ultrasonic pressure wave, through the transmission
medium, representative of the inverted-noise modulated ultrasonic
signal.
[0022] In some embodiments, the sound is sampled at a plurality of
locations in the listening environment. One of the target locations
may include a dance floor of a venue environment.
[0023] In some embodiments, the listening environment is a venue
having a plurality of audio and video monitors distributed within
the venue.
[0024] In some embodiments, ultrasonic waves modulated according to
a message may be intentionally bounced off specific surfaces to
facilitate the sound traveling to particular places. Consequently,
sound may effectively "travel" silently through the air until it
hits a surface.
[0025] The method may include providing a wireless link between one
or more mobile devices at the one or more target locations and a
venue control center at the venue in some embodiments.
[0026] In some embodiments, the method includes modulating the one
or more audio signals with ultrasonic carrier signals to produce
one or more modulated ultrasonic carrier signals; determining the
location of one or more targets using an indoor positioning system;
and directing one or more ultrasonic pressure waves, representative
of the one or more modulated ultrasonic carrier signals, through a
transmission medium, at the one or more targets, wherein in
connection with the one or more ultrasonic pressure waves reaching
the one or more targets, the one or more modulated ultrasonic
carrier signals demodulate.
[0027] In some embodiments, servers or workers may hear/speak to
guests via earpiece and microphone in connection with the indoor
positioning system.
[0028] In some embodiments, the method includes the indoor
positioning system using a positioning system selected from the
group consisting of a proximity-based system, a wireless-based
system, an ultrawide-band system, an acoustic system, an infrared
system, and a combination thereof.
[0029] In some embodiments, the wireless-based system determines
location based on time difference of arrival (TDOA).

[0083] FIG. 1 illustrates a diagram showing a directed sound
transmission system 110, which, in some embodiments, serves as an
ultrasonic transducer that modulates audio information on an
ultrasonic carrier, producing a modulated carrier signal. A
pressure wave may be produced within a transmission medium
according to the modulated carrier signal, which may demodulate the
pressure wave striking a surface. In some embodiments, the directed
sound transmission system 110 serves as an apparatus for directing
sound waves restricted to a particular listener in a queue area
(also known as a queue line 118, shown in FIG. 1, and used
interchangeably with the queue area). As illustrated in FIG. 1, the
directed sound transmission system 110 may include directed at
least one sound source 114, located at positions along the queue
line 118. A microphone 120 may be coupled to a video camera
130.
[0084] The video camera 130 may include any type of camera
configured to capture video images. In some embodiments, the video
camera 130 comprises a closed-circuit television system (CCTV)
system 130, which, in many embodiments, is operable to control the
sound transmission system 110. Modern CCTV systems are
contemplated, which include CCTV systems having one or more: high
definition cameras; dark fighter technology cameras; internal and
external dome cameras; bullet camera; C-mount cameras; day/night
camera; a pan/tilt/zoom (PTZ) cameras; thermal imaging cameras;
infrared cameras; varifocal cameras; network cameras; discreet CCTV
cameras; automatic number plate recognition ANPR) cameras; license
plate reading (LPR) cameras; and CCTV systems having combinations
of the preceding cameras.
[0085] Regarding FIGS. 1 and 6, which will be discussed later in
the disclosure, as individuals pass through the queue line 118,
sound may be directed to targeted individuals 134, 137 in the queue
line 118 in connection with estimated locations as determined by
the queue line monitoring system 210. In this manner, one or more
individuals may be sent messages, via sound modulated over an
ultrasonic carrier, throughout an experience while standing in a
queue area/line. Queue line monitoring system 210 also serves to
provide "gamification" of the process of waiting in line, thereby
helping to blur the perception of time while in a queue (line).
[0086] FIG. 2 illustrates a perspective view of another embodiment
with particular suitability for use in a bar or restaurant. In
venue 300, having multiple video displays 302, and with attendant
audio, a directed sound transmission system 110 may be implemented
using a controller 301 coupled via antenna 315 to a number of
directed sound source(s) 114 distributed within the venue 300.
Controller 301 may control aspects of the directed sound
transmission system 110 using a wireless link. Even while in a
noisy environment, while watching a specific video display 302,
subjects 312, 314 in venue 300 may listen (in connection with
receiving sound pressure waves 310) to a selection of their
choosing by selecting programs in connection with the table
controller 318 on table 320. In some embodiments, the table
controller 318 may have one or more microphones (not shown) for
facilitating communications within the venue 300.
[0087] In some embodiments, a translation system 204, shown in FIG.
6 and discussed later in this disclosure, may be included in or
coupled to controller 301 of the directed sound transmission system
110. Live translations of audio selections may be provided to
subjects 312, 314 in a language of their choosing in connection
with the translation system 204 performing translations locally or
remotely using one or more processors programmed to translate
language and synthesize speech for modulation on an ultrasonic
carrier as disclosed herein.
[0088] FIG. 3 illustrates a perspective drawing of an embodiment
that further supplements the embodiments described with respect to
FIG. 2. A wireless link may be established through a wearable
device 402 (shown in FIG. 3 as a noise-canceling headset), which is
contemplated as wearable devices (e.g., tags, lanyard-worn devices,
etc. worn by worker 404, such as a waiter or waitress) waiting
tables 320 in a restaurant or bar.
[0089] In some embodiments, communication with worker 404 may be
effectuated using a directed sound transmission system 110 as
described concerning FIGS. 1 and 6 using an ultrasonic carrier.
Wearable device 402 may provide a link to an indoor positioning
system 420, which may be used for locating worker 404 within venue
300. An indoor positioning system 420 may include a Wi-Fi-based
system, a proximity-based system, an acoustic system, an
ultra-wideband system, and/or an infrared system.
[0090] Patron 440 (who may be standing or seated within an area in
a venue 300) may place an order through worker 404 in connection
with the indoor positioning system 420 locating worker 404 in the
venue 300. In some embodiments, controller 301 facilitates
communication with worker 404 in conjunction with the indoor
positioning system 420 to cause a verbal request from patron 440 to
reach worker 404 over a modulated ultrasonic carrier using a
directed sound source 114. In some embodiments, the directed sound
source 114 may mounted be on a swivel (not shown) configured to
rotate toward a direction aimed at a designated location that
worker 404 frequents or directly at the location determined for
worker 404.
[0091] The position of worker 404 may be determined using a
proximity-based system. One such system uses transponders, such as
radio frequency identification (RFID) tags, which work with
beacons, distributed within a venue 300 that wirelessly interacts
with the RFID tags to calculate the location of the tags based on
the signal strength of received signals from the RFID tags. In some
embodiments, worker 404 may wear an RFID tag (not shown). In some
embodiments, signals sent from the beacons (not shown), distributed
within venue 300, impart energy to the RFID tags, which send their
identification numbers and signal strengths back to the beacons.
The beacons relay this information to a computer/server (not shown)
from which the position location of worker 404 in venue 300 may be
calculated.
[0092] In some embodiments, the position of worker 404 may be
determined using a Wi-Fi-based system. Worker 404 may wear wearable
device 402, which serves as a tag that contains a Wi-Fi transmitter
(not shown) that may send communication packet information to a
number of Wi-Fi access points (not shown) distributed within venue
300. The access points report the time and signal strength to a
computer/server that may calculate the position of worker 404 based
on time difference of arrival (TDOA) measurements.
[0093] An acoustic indoor positioning system 420 may also be used
to locate worker 404 within venue 300. Ultrasonic pulses may be
sent from wearable device 402, which can be used by indoor
positioning system 420 to locate worker 404 in connection with
directing message modulated on an ultrasonic carrier.
[0094] Infrared indoor location systems may also be contemplated
for locating worker 404 to send a message modulated on an
ultrasonic carrier. In these embodiments, infrared readers may be
distributed throughout venue 300, and wearable device 402, worn by
worker 404, may send pulses to the readers. Location position can
be determined based on these pulses.
[0095] In some embodiments, worker 404 may be connected wirelessly
to controller 301, which may forward communications wirelessly from
patron 440 to wearable device 402, such as a headset. Table
controller 318, as shown in FIG. 2, may be wirelessly linked to
worker 404. Conversations may be had between patron 440 and worker
404 using a microphone (not shown) at table controller 318,
wearable device 402 (having a microphone and at least one speaker),
and the directed sound transmission system 110 as described
herein.
[0096] The preceding embodiments may include a sound abatement
system 450 implemented within or coupled thereto, the directed
sound transmission system 110, and controller 301. More
particularly, the embodiments described herein may use Gaussian
white noise generated by a Gaussian noise generator (not shown) in
the sound abatement system 450. Alternatively, the sound abatement
system 450 may use a noise cancellation system (not shown)
implemented within or coupled to sound abatement system 450.
[0097] Referring now to FIG. 4, a perspective view of voice
recognition system 702 employing multiple parametric speakers (also
referenced herein as directional speakers, as shown in FIG. 5) for
sending audio sound on an ultrasonic carrier to individuals
identified by the voice recognition system 702 is shown. Multiple
microphones (each labeled 760) may be distributed throughout venue
300, which may be used to sample voices of individuals at venue
300. A protocol may be established before using the voice
recognition system 702 that permits the sampling of an individual's
voice audio. In some embodiments, a voice signature through which
an individual may be identified is created. The voice signature and
associated information may be stored in a memory coupled to the
voice recognition system 702. Communications with recorded voice
signatures may prefix a voice message for an intended message
receiver within a venue 300. Other records, including patron
position location, stored patron preferences, and patron historical
data, may be maintained in a memory and accessed for various
customer service purposes. For example, a patron 440 may enter the
venue 300, and a voice sample may be taken. Microphone 760 may
receive communications from a patron 400. In many embodiments, the
voice recognition system 702 includes a processor 770, which
produces an output, herein referenced as voice signature, used to
identify an individual's voice using voice samples collected by
microphone 760 and stored in memory 780. Memory 780, coupled to
voice recognition system 702, may represent a local or remote
storage device/system for use with voice recognition system 702. A
patron 440 associated with a stored voice signature may be further
associated with historical information such as past food and/or
drink orders, past seating locations, past servers, detailed tip
information, and spending history. This historical information may
be stored in a relational database along with its associated voice
signature. Such a system may be configured to permit the preceding
data/information discussed herein to be shared over the network
with other venues.
[0098] It may be desirable to deliver messaging with high accuracy
in reaching a targeted message receiver. As such, in some
embodiments, wearable RFID tags may be distributed to patrons in a
venue to help to ensure accurate delivery of messages placed on an
ultrasonic carrier.
[0099] FIG. 5 illustrates a perspective drawing showing a directed
sound transmission system 110 wherein patrons 440 wearing a
wearable device, such as RFID tag 802, are tracked within a venue
300 using an indoor positioning system 420, as shown in FIG. 4.
Directional/Parametric speakers 804 may be distributed throughout
venue 300. Some of the speakers 804 may lie on a swivel 810, which
may be positioned (through a wireless or wired connection) via
communication system 806, by controller/processor 820 to direct
sound toward a particular patron 440 as determined in connection
with the RFID tag 802 worn by the patron 440. In some embodiments,
the RFID tag 802 comprises a lanyard RFID tag. In some embodiments,
the lanyard RFID tag is a UHF 915 MHz lanyard RFID tag. In some
embodiments, the RFID tag is any type of device capable of being
tracked via RFID whereby the RFID tag is temporarily coupled to a
patron.
[0100] The use of dynamic range compression (DRC) is contemplated
for use with the previously described embodiments herein. DRC may
be used to provide both downward and upward compression, thereby
reducing the decibel level of sound above a given threshold level.
In some cases, it may be used to increase the decibel level of
quieter sounds.
[0101] Sound conditioners 848 may also be employed using the
previously described embodiments, as illustrated in FIG. 5.
Accordingly, a sound conditioner 848 may adjust the gain of a
parametric speaker 804 sounding a message on a modulated carrier as
a function of frequency and input level. Alternatively, the sound
conditioner 848 may adjust the gain, as a function of frequency and
input level, before being input to a parametric speaker 804.
[0102] Higher frequency hearing loss may occur for a patron 440 or
a worker 404 of an identified age category. A sound conditioner 848
may adjust the level of the higher frequencies to compensate for a
range of possible frequency-dependent hearing loss.
[0103] Sound conditioner 848 is shown in FIG. 5 as being at least
one of communicatively, electrically, and mechanically coupled to
controller/processor 820. Memory 860, which may be connected
locally or remotely to controller/processor 820, may contain
specific hearing loss data for various age groups. In connection
with directed sound from directional/parametric speakers 804, sound
conditioner 848 may adjust the gain levels of a
directional/parametric speaker 804 output accordingly to compensate
for hearing loss as indicated with stored data on memory 860 as
correlated with available profile information as discovered for a
patron 440. Controller/processor 820 may be connected to network
880 through which patron data may be discoverable online. For
instance, a patron 440 may register at venue 300. Online data may
indicate the age of the patron 440 as being 50 years old. From
average hearing profiles stored in memory 860 or accessed online,
sound conditioner 848 can compensate for frequency-related hearing
loss by adjusting gain levels of certain frequencies per a relevant
age-related hearing profile.
[0104] FIG. 6 illustrates a schematic representation of a directed
sound transmission system 110, such as the directed sound
transmission system 110 shown in FIG. 1. In some embodiments, the
directed sound transmission system 110 includes at least one
directed sound source 114. A translation system 204 may be coupled
to the directed sound transmission system 110. The translation
system 204 may be coupled to a microphone system 206, including one
or more microphones 120 for sampling sound at positions along the
queue line 118, as shown in FIG. 1. In some embodiments, the
directed sound transmission system 110 includes a queue line
monitoring system 210. The queue line monitoring system 210 may be
coupled to a processor 250 (e.g., an application processor) and a
memory 260 having program instructions, that when executed by
processor 250, causes calculation of a queue rate, associated with
the queue line 118, which can be used to send directed sound from
the directed sound transmission system 110, as described herein, to
a target in the queue line 118. Queue line monitoring system 210
may also be used to monitor positions of individuals in the queue
line 118 through video surveillance of the queue line 118 in
connection with monitoring by at least video camera 130 (as shown
in FIG. 1), which may be placed at various positions along queue
line 118. In some embodiments, a queue rate of queue progress or,
in some instances, a queue position is determined in connection
with video surveillance, electronic monitoring of individuals in a
queue line by non-video methods, and combinations of video and
non-video monitoring. In some embodiments, memory 260 contains
program instructions that, when executed by processor 250 (e.g., an
open-source processor), cause the directed sound transmission
system 110 to direct sound as described herein.
[0105] In some embodiments, processor 250 exists locally on a
hardware system programmed according to program instruction
downloaded to memory 260 from remote server 268. In some
embodiments, processor 250 exists on a hardware system, located
remotely from some elements of directed sound transmission system
110, and operates according to program instruction downloaded from
remote server 268. The processor 250 may comprise a music
processor.
[0106] In some embodiments, the microphone system 206 takes sound
samples from various location positions along the queue line 118,
shown in FIG. 1. Translation system 204 may determine languages
spoken by individuals at those location positions in the queue line
118. In some embodiments, in connection with determining the queue
rate associated with traffic in queue line 118, a message is sent
to the targeted individuals 134, 137, or targeted locations in the
language determined from the sound samples. Translation system 204,
which may contain or may be coupled to one or more processors, may
translate a message into a given language. Directed sound
transmission system 110 may be used to send translated messages on
a modulated ultrasonic carrier in the given language to targeted
individuals or targeted locations along the queue line 118.
[0107] A queue line monitoring system 210 may contain a receiver
(not shown), which in some embodiments receives location data from
a wearable device (not shown) from individuals in the queue line
118. In some embodiments, the wearable device contains an active or
passive radio frequency identification (RFID) tag, which emanates
stored information in connection with stored battery power or in
connection with an energy-imparting stimulus. An RFID system may be
incorporated within or connected to the queue line monitoring
system 210. Processor 250 may be programmed to calculate queue
rates or position locations using the RFID tags with information
from the RFID tags or information from the RFID tags combined with
video surveillance of the queue line 118.
[0108] FIG. 7 illustrates a flowchart showing communication steps
for sending a message to an individual or a group of individuals in
a queue line 118, as shown in FIG. 1. Initially, at step 7000, a
message is determined for dispatch. This message may, for example,
be generated by a person or by a processor in a computer system.
The message may be stored in a computer memory before dispatch. As
queue line 118 is in motion, the targeted individual(s) to receive
the message is (are) likewise in motion. It is advantageous to
determine the position (by position, meaning location) of the
individual(s) to receive the message and/or the position of the
individuals in queue line 118 to direct a message on a modulated
carrier accurately. Once the position/location of the targeted
individual(s) to receive a message is determined, at step 7002, the
message is dispatched as indicated at step 7004.
[0109] FIG. 8 illustrates a flowchart showing communication steps,
for another embodiment, for sending a message to an individual or a
group of individuals in a queue line 118, as illustrated in FIG. 1.
Initially, at step 8000, a message is determined for dispatch. This
message may, for example, be generated by a person or by a
processor in a computer system. The message may be stored in a
computer memory before dispatch. As queue line 118 is in motion,
the targeted individual(s) to receive the message is (are) likewise
in motion. It is advantageous to determine the position (by
position, meaning location) of the individual(s) to receive the
message and/or the position of the individuals in queue line 118 to
direct a message on a modulated carrier accurately. Determining the
queue rate, as shown in FIG. 8 at step 8002, facilitates
determining the position of the target(s) (individual(s)) to
receive a message modulated on an ultrasonic carrier. Once the
position/location of the targeted individual(s) to receive a
message is determined, the message is dispatched as indicated in
step 8004.
[0110] FIG. 9 shows a flowchart illustrating the foregoing steps
detailing embodiments of communicating with a worker 404 in a venue
300 such as a bar or a restaurant. In some embodiments, at step
9000, a message is prepared for the worker 404 that may be spoken,
for instance, into a microphone at table 320 in the bar or
restaurant. The microphone's location is known and may be held in a
memory for use by a processor for facilitating service to table 320
by worker 404. The location of worker 404 may be determined, at
step 9002, by one of the indoor positioning methods noted above. In
connection with parametric speaker systems distributed throughout
the bar or restaurant venue, the message may be directed at worker
404 over a parametric speaker on an ultrasonic carrier, at step
9004. In some embodiments, worker 404 may respond to a patron 440
using a microphone from a station connected to the table area from
which service is requested. In some embodiments, a worker 404 may
use a noise-canceling headset while still receiving a message from
a patron 440 delivered over an ultrasonic carrier, at step
9006.
[0111] FIG. 10 illustrates a flowchart of another embodiment
illustrating the foregoing steps detailing an embodiment of
communicating with a worker 404 in a venue 300 such as a bar or a
restaurant. A message is prepared which may be spoken, by a patron
440, into, for instance, a microphone at table 320 in the bar or
restaurant, at step 10000. The message may be dispatched to a
worker 404 or workers at specific locations within a bar or
restaurant using the directed sound transmission system described
above, at step 10002. For instance, orders may be received directly
in the kitchen or at the bartending area. A directed sound
transmission system 110 may note the location of the message
sender, and the worker 404 may respond to the patron 440, at step
10004.
[0112] When directed sound is received as a spoken message, it may
be desirable to employ a voice recognition system such that the
recipient of a message may readily determine the speaker. In
addition, a directed speaker system may add the identity of the
party speaking as an introductory announcement before the message
being conveyed.
[0113] FIG. 11 illustrates a block diagram of the directed message
system having voice recognition as described above. In some
embodiments, a patron 440 speaks a message for delivery to a worker
404, at step 11000. The directed message system may determine the
location of the worker 404, at step 11002. Using voice recognition,
the system may be configured to identify the speaker, at step
11004. In some embodiments, as previously discussed in this
disclosure, the message is transmitted over an ultrasonic carrier,
at step 11006.
[0114] In some embodiments, the directed sound system (also known
as a parametric sound system) may be used to send subliminal
messages to a patron in a queue line, bar, restaurant, or relevant
venue. Some of the messaging may be designed to be barely audible
or at frequencies likely heard by some and not others. Demographic
information may dictate the type of message for delivery and/or the
time of delivery. In a bar or restaurant setting, drink specials
may be subliminally announced over a parametric sound system based
on demographic information accessed online or collected for a
patron or a particular group of patrons.
[0115] Live location maps detailing the location of patrons in a
venue may be constructed by a processor receiving information, as
noted herein. The processor may be programmed accordingly, and it
may represent one of the processors disclosed herein. Voice,
demographics, and other personal information can be used
collectively to establish live location mapping for a venue. As
disclosed herein, messaging over a parametric speaker system can be
used with the live location mapping to establish targets for
messaging and messages selected in connection with the
targeting.
[0116] The disclosure also includes various embodiments as further
described. In some embodiments, patrons standing in a queue line
may receive messages via a directed sound over a parametric speaker
system to deliver an audio message modulated on an ultrasonic
carrier. A processor may determine a queue rate (i.e., the rate of
queue line movement) for a queue line. The queue rate is reflective
of the speed of the line and knowing this parameter can help
determine where specific patrons are in a line to better facilitate
the directing of a message to them over the parametric speaker
system.
[0117] Additionally, in some embodiments, patrons standing in a
queue line may receive messages via a directed sound over a
parametric speaker system to deliver an audio message modulated on
an ultrasonic carrier. A processor may determine a queue rate
(i.e., the rate of queue line movement) for a queue line. The queue
rate is reflective of the speed of the line and knowing this
parameter can help determine where specific patrons are in a line
to better facilitate the directing of a message to them. In
addition to understanding and using the queue rate, visual
surveillance of the queue line can help identify the location of an
individual or individuals in a queue line. A processor may be
programmed to process data from the visual surveillance information
and determine that individual's location or those individuals using
queue rate information and visual surveillance data.
[0118] Even still, in some embodiments, patrons standing in a queue
line may receive messages via a directed sound over a parametric
speaker system for delivery of an audio message modulated on an
ultrasonic carrier. Patrons may wear an RFID tag. A positioning
system associated with the queue line may determine a patron's
location, in connection with the worn RFID tag, at a given time to
facilitate the directing of a message to the patron over the
parametric speaker system.
[0119] In some embodiments, patrons standing in a queue line may
receive messages via a directed sound over a parametric speaker
system to deliver an audio message modulated on an ultrasonic
carrier. A processor may determine a queue rate (i.e., the rate of
queue line movement) for a queue line. The queue rate is reflective
of the speed of the line and knowing this parameter can help
determine where specific patrons are in a line to better facilitate
the directing of a message to them over the parametric speaker
system. Further, sound samples of the patrons may be taken at one
or various points along the queue line. Such may be accomplished,
for instance, using one or more directional microphones. A
processor may process the sound samples to determine an associated
language with the particular sound samples to identify the spoken
language of a speaking patron in the queue line. One or more of the
location identification techniques, as disclosed herein, may be
used to determine the location of a patron in the queue line, and
messages may be delivered to the patron in the spoken language
determined for that patron.
[0120] Furthermore, in some embodiments, patrons standing in a
queue line may receive messages via a directed sound over a
parametric speaker system to deliver an audio message modulated on
an ultrasonic carrier. Voice sound samples may be taken from
patrons at a given position or given positions in the queue line.
In some embodiments, patrons may be identified based on the sound
samples using a voice recognition system. Messages may be directed
at a specific patron over the parametric speaker system, as
identified through the voice recognition system.
[0121] Additionally, in some embodiments, patrons standing in a
queue line may receive messages via a directed sound over a
parametric speaker system to deliver an audio message modulated on
an ultrasonic carrier. Voice sound samples may be taken from
patrons at a given position or given positions in the queue line.
Patrons may be identified based on the sound samples using a voice
recognition system. Messages may be directed at a specific patron
over the parametric speaker system, as identified through the voice
recognition system. The delivery of those messages to the
particular patron may be further facilitated by using position
location for the patron in connection with queue rate determination
and/or an RFID tag worn by the patron.
[0122] Also, in various embodiments, patrons in queue lines may
receive messages via a directed sound over a parametric speaker
system to deliver an audio message modulated on an ultrasonic
carrier. Voice sound samples may be taken from patrons at a given
position or given positions in the queue line. Patrons may be
identified based on the sound samples using a voice recognition
system. Messages may be directed at a specific patron over the
parametric speaker system, as specified through the voice
recognition system. The delivery of those messages to the
particular patron may be further facilitated by using position
location for the patron in connection with queue rate determination
and/or an RFID tag worn by the patron. Speech recognition, as
disclosed herein, may be used to determine the speaking language of
a patron, and messages may be sent to that patron in the speaking
language determined for that patron.
[0123] In connection with the embodiments described herein, online
information may be accessed to determine relevant demographics for
a patron standing in a queue line. Message delivery methods used in
conjunction with one or more patron location determination methods
described herein may be used to facilitate the delivery of messages
to a patron in a relevant language and with sound conditioning
identified as applicable for that patron based on those relevant
demographics.
[0124] In some embodiments, patrons standing in a queue line may
receive messages via a directed sound over a parametric speaker
system to deliver an audio message modulated on an ultrasonic
carrier. Patrons may wear an RFID tag or carry an RFID key card.
Information collected in connection with issuing an RFID tag/key
card or accessing information online as determined from the RFID
tag/key card may be used to direct specific messages to patrons
standing in line. Some of these messages may be related to
demographic information determined for a particular patron. Other
personal information specified for the patron may also be used to
direct messages to that patron. For instance, online information
accessed concerning a patron in an amusement park setting may
identify a 40-year-old female from France. Further demographic
details accessed may show that the 40-year-old French patron may be
interested in the location of vendors selling cappuccino coffee at
1:00 PM. Accordingly, that patron may be specifically targeted to
receive cappuccino messages at certain times while standing in
line. A positioning system associated with the queue line may
determine a patron's location, in connection with the worn/carried
RFID tag/key card, at a given time to facilitate the directing of a
message to the patron over the parametric speaker system.
Consequently, a queue rate processor used for determining a queue
rate may be coupled/tied to a GPS, an RFID reader, or both to
determine the location of a message recipient.
[0125] In some embodiments, one-way and two-way direct/live
communication may occur between workers/entertainers and guests
standing in a queue. For example, the voice of Peter Pan.TM. may be
used to converse with a guest who's in line for a Peter
Pan.TM.-themed ride at Disneyland. In some instances, an actual
person may speak with someone standing in line. In other cases, a
pre-recorded message may be sent to patrons standing in line.
[0126] Even still, in some embodiments, individuals in a queue line
may be targeted to receive subliminal messaging based on
demographic or other information in connection with the examples
disclosed herein using the parametric speaker system herein. The
demographic or other information may be accessed online or stored
in a memory-holding demographic and/or personal data.
[0127] Furthermore, in connection with the embodiments described
herein, online information may be accessed to determine relevant
demographics for a patron standing in a queue line. Message
delivery methods used in conjunction with one or more patron
location determination methods described herein may be used to
facilitate delivery of messages to a patron in a relevant language
and with sound conditioning identified as applicable for that
patron based on the appropriate demographics. That demographic
information may include age information. The age information may be
correlated with specific audio frequencies identify as challenging
to hear as regarded for a particular age group. A sound conditioner
may condition messages for those patrons matching a specific
demographic to compensate for age-related hearing decline.
[0128] In some embodiments, patrons in a bar or restaurant setting
may receive directed audio using a parametric speaker system
connected with a venue having several display monitors. The
delivery of this directed audio may be facilitated by multiple
parametric speakers distributed throughout a venue.
[0129] Various embodiments include a venue having a parametric
sound system that may accommodate a patron contacting a waiter or
waitress using that system. In connection with an indoor
positioning system, a waiter or waitress may be located within an
establishment. The speakers of the parametric sound system may be
used and/or physically directed to send sound over an ultrasonic
carrier to the waiter or waitress as guided by the indoor
positioning system.
[0130] In some embodiments, ultrasonic waves modulated according to
a message may be intentionally bounced off specific surfaces to
better facilitate the sound traveling to specific places.
Consequently, sound may effectively "travel" silently through the
air until it hits a surface.
[0131] Additionally, in some embodiments, a venue having a
parametric sound system may accommodate patrons contacting a waiter
or waitress using that system. In connection with an indoor
positioning system, a waiter or waitress may be located within an
establishment. The speakers of the parametric sound system may be
used and/or physically directed to send sound over an ultrasonic
carrier to the waiter or waitress as guided by the indoor
positioning system.
[0132] Some embodiments include a venue having a parametric sound
system that may accommodate patrons contacting a waiter or waitress
using that system. In connection with an indoor positioning system,
a waiter or waitress may be located within an establishment. The
speakers of the parametric sound system may be used and/or
physically directed to send sound over an ultrasonic carrier to the
waiter or waitress as guided by the indoor positioning system. The
waiter or waitress may respond to the patron using headphones
connected by a wireless link to a speaker.
[0133] Also, in some embodiments, patrons in a bar or restaurant
setting may receive directed audio using a parametric speaker
system in connection with a venue having several display monitors.
The delivery of this directed audio can be facilitated by multiple
parametric speakers distributed throughout a venue. One or more
processors may translate audio associated with the display monitors
into the language of a patron or patrons. One or more speech
synthesizers may provide translated audio as delivered by the
parametric speaker system as disclosed herein.
[0134] In some embodiments, a venue having a parametric sound
system may accommodate patrons contacting a waiter or waitress
using that system. In connection with an indoor positioning system,
a waiter or waitress may be located within an establishment. The
speakers of the parametric sound system may be used and/or
physically directed to send sound over an ultrasonic carrier to the
waiter or waitress as guided by the indoor positioning system.
Sampled sounds for table locations at a bar or restaurant may be
used to identify patrons within that venue. Distributed microphones
within a venue may sample sound information to allow a processor to
establish live location maps for the patrons within a venue. The
waiter or waitress may respond to the patron using headphones
connected by a wireless link to a speaker.
[0135] According to some embodiments, a live location map detailing
the location of patrons within a venue may be constructed by a
processor receiving information, as noted herein. The processor may
be programmed accordingly, and it may represent one of the
processors disclosed herein. Voice, demographics, and other
personal information can be used collectively to establish live
location mapping for a venue. As disclosed herein, messaging over a
parametric speaker system can be used with the live location
mapping to establish targets for messaging and messages selected in
connection with the targeting. In view of the foregoing, the
parametric sound system, as disclosed herein, may send multiple
messages in the manner described herein to multiple patrons in a
venue. Those messages may reflect demographic data, personal
preferences, and preferences established during a visit to an
establishment. Consequently, alcohol consumption can be monitored
and limited for a patron based on alcohol orders for an evening
within the establishment, thereby limiting dram shop law violations
wherein a commercial vendor may be held liable for injuries and
damages based on the sale of alcohol to an inebriated person.
[0136] Additionally, according to some embodiments, a live location
map detailing the location of patrons within a venue may be
constructed by a processor receiving information, as noted herein.
The processor may be programmed accordingly, and it may represent
one of the processors disclosed herein. Voice samples taken from
patrons within an establishment may establish a voice signature for
a patron. Voice signature, demographic, and other personal
information can be used collectively to establish live location
mapping for a venue. As disclosed herein, messaging over a
parametric speaker system can be used with the live location
mapping to establish targets for messaging and messages selected in
connection with the targeting. In view of the foregoing, the
parametric sound system, as disclosed herein, may send multiple
messages in the manner described herein to multiple patrons in a
venue. Those messages may reflect demographic data, personal
preferences, and preferences established during a visit to an
establishment. Consequently, alcohol consumption can be monitored
and limited for a patron based on alcohol orders for an evening
within the establishment. The voice signature and other demographic
and personal information collected during a patron visit may be
stored in a memory (online or locally) for future reference and/or
use.
[0137] Dynamic range compression (DRC) may be implemented with the
parametric speaker embodiments described herein. DRC may be used to
provide both downward and upward compression, thereby reducing the
decibel level of sound above a given threshold level. In some
cases, it may be used to increase the decibel level of quieter
sounds. The DRC may be used to limit harmful noise and/or to
compensate for hearing loss.
[0138] White Gaussian noise sound conditioning techniques may be
implemented with the parametric speaker embodiments described
herein. As well, noise-canceling methods may be implemented with
the parametric speaker embodiments described herein.
[0139] The foregoing disclosure may be implemented in a setting
such as the United Nations. Parametric speakers may direct sound to
specific individuals/seating locations without significantly adding
to the ambient noise of the environment. Each party, receiving
directed sound from a parametric speaker, may be located proximate
to the parametric speaker. The parametric speaker may receive a
wireless signal having a modulated carrier according to one or more
of the following systems: a radio frequency system; a code
divisional multiple access (CDMA) system; a frequency divisional
multiple access (FDMA) system; a time division multiple access
(TDMA) system; an orthogonal frequency division system; an
orthogonal frequency division multiple access system; an infrared
system; a Wi-Fi system; a Bluetooth.RTM. system; and combinations
thereof.
[0140] Entities at the United Nations generally address the forum
via translators. A software application for a processor programmed
to translate languages from one language to another may be employed
at each parametric speaker location, at the location of each party
presenting, or through a mobile device (e.g., smartphone, tablet,
etc.) of each receiving location. Given the potential hearing
damage associated with headphones, it may be advantageous to
receive translated communications without the need for headphones
and in a manner that does not significantly increase ambient noise
levels. In some embodiments, systems may implement speech synthesis
to convey the translated communications to the party intended for
the communications.
[0141] In some embodiments, the disclosure includes a method for
communications comprising receiving a message, wirelessly using
radio frequency signals at a mobile device, demodulating the
message at the mobile device, and translating audio information in
the message from a first language to a second language. In some
embodiments, the method includes modulating the transmission on an
ultrasonic carrier to produce a modulated ultrasonic carrier and
directing the modulated ultrasonic carrier to an intended receiver
through a parametric speaker.
[0142] Another communication method may include translating audio
information from a first language to a second language, wirelessly
receiving, at a mobile device and via radio frequency signals, a
message containing the audio data in the second language, and
demodulating the message at the mobile device. In some embodiments,
the method includes modulating the message on an ultrasonic carrier
to produce a modulated ultrasonic carrier and directing the
modulated ultrasonic carrier, through a parametric speaker, to an
intended receiver.
[0143] In some embodiments, a communication method comprises
wirelessly receiving, via radio frequency signals, a message
containing audio information, demodulating the message, translating
the audio data from a first language to a second language. In some
embodiments, the method includes modulating the message on an
ultrasonic carrier to produce a modulated ultrasonic carrier and
directing the modulated ultrasonic carrier, through a parametric
speaker, to an intended receiver.
[0144] The disclosure also includes a system having a speaker
comprising a receiver, the receiver being operable to receive
wireless signals from the group consisting of radiofrequency (RF)
signals, infrared signal, microwave signals, and any combination
thereof. The system may also include a demodulator, the demodulator
being operable to demodulate wireless signals, and an ultrasonic
modulator.
[0145] In some embodiments, a method of providing focused beam
directional sound comprises selecting one or more audio messages
determined in connection with demographic information, modulating
the one or more audio messages with ultrasonic carrier signals to
produce one or more modulated ultrasonic carrier signals,
determining the location of one or more targets using an indoor
positioning system, and directing one or more ultrasonic pressure
waves, representative of the one or more modulated ultrasonic
carrier signals, through a transmission medium, at the one or more
targets. In connection with the one or more ultrasonic pressure
waves reaching the one or more targets, the one or more modulated
ultrasonic carrier signals may demodulate. The one or more audio
messages may include a subliminal message. In some embodiments, the
indoor positioning system comprises a voice recognition system.
[0146] The method may further comprise using dynamic range
compression (DRC) to provide compression of a received message sent
by way of the one or more ultrasonic pressure waves. In some
embodiments, the method further comprises translating the one or
more audio messages to one or more audio messages of a
predetermined language.
[0147] The indoor positioning system may comprise an ultrawide-band
indoor positioning system. In some embodiments, the indoor
positioning system is a proximity-based indoor positioning system.
The indoor positioning system may include an infrared indoor
positioning system. In some embodiments, the indoor positioning
system is an acoustic indoor positioning system. The one or more
audio messages may be selected based on age-related demographic
information.
Interpretation
[0148] None of the steps described herein is essential or
indispensable. Any of the steps can be adjusted or modified. Other
or additional steps can be used. Any portion of any of the steps,
processes, structures, and/or devices disclosed or illustrated in
one embodiment, flowchart, or example in this specification can be
combined or used with or instead of any other portion of any of the
steps, processes, structures, and/or devices disclosed or
illustrated in a different embodiment, flowchart, or example. The
embodiments and examples provided herein are not intended to be
discrete and separate from each other.
[0149] The section headings and subheadings provided herein are
nonlimiting. The section headings and subheadings do not represent
or limit the full scope of the embodiments described in the
sections to which the headings and subheadings pertain.
[0150] The various features and processes described above may be
used independently of one another or combined in various ways. All
possible combinations and subcombinations are intended to fall
within the scope of this disclosure. In addition, certain methods,
events, states, or process blocks may be omitted in some
implementations. The methods, steps, and processes described herein
are also not limited to any particular sequence, and the blocks,
steps, or states relating thereto can be performed in other
sequences that are appropriate. For example, described tasks or
events may be performed in an order other than the order
specifically disclosed. Multiple steps may be combined in a single
block or state. The example tasks or events may be performed in
serial, parallel, or some other manner. Tasks or events may be
added to or removed from the disclosed example embodiments. The
example systems and components described herein may be configured
differently than described. For example, elements may be added to,
removed from, or rearranged compared to the disclosed example
embodiments.
[0151] Conditional language used herein, such as, among others,
"can," "could," "might," "may," "e.g.," and the like, unless
specifically stated otherwise, or otherwise understood within the
context as used, is generally intended to convey that certain
embodiments include. In contrast, other embodiments do not include
certain features, elements, and/or steps. Thus, such conditional
language is not generally intended to imply that features,
elements, and/or steps are in any way required for one or more
embodiments or that one or more embodiments necessarily include
logic for deciding, with or without author input or prompting,
whether these features, elements and/or steps are included or are
to be performed in any particular embodiment. The terms
"comprising," "including," "having," and the like are synonymous
and are used inclusively, in an open-ended fashion, and do not
exclude additional elements, features, acts, operations, and so
forth. Also, the term "or" is used in its inclusive sense (and not
in its exclusive sense) so that when used, for example, to connect
a list of elements, the term "or" means one, some, or all of the
elements in the list. Conjunctive language such as the phrase "at
least one of X, Y, and Z," unless specifically stated otherwise, is
otherwise understood with the context as used in general to convey
that an item, term, etc. may be either X, Y, or Z. Thus, such
conjunctive language is not generally intended to imply that
certain embodiments require at least one of X, at least one of Y,
and at least one of Z to each be present.
[0152] The term "and/or" means that "and" applies to some
embodiments and "or" applies to some embodiments. Thus, A, B,
and/or C can be replaced with A, B, and C written in one sentence
and A, B, or C written in another sentence. A, B, and/or C means
that some embodiments can include A and B, some embodiments can
include A and C, some embodiments can include B and C, some
embodiments can only include A, some embodiments can include only
B, some embodiments can include only C, and some embodiments can
include A, B, and C. The term "and/or" is used to avoid unnecessary
redundancy.
[0153] The term "adjacent" is used to mean "next to or adjoining."
For example, the disclosure includes "the at least one directed
sound source is located adjacent a head of the user." In this
context, "adjacent a head of the user" means that at least one
directed sound source is located next to the user's head. The
placement of the at least one directed sound source in a ceiling
above the user's head, such as in a vehicle ceiling, would fall
under the meaning of "adjacent" as used in this disclosure.
[0154] While certain example embodiments have been described, these
embodiments have been presented by way of example only and are not
intended to limit the scope of the inventions disclosed herein.
Thus, nothing in the foregoing description is intended to imply
that any particular feature, characteristic, step, module, or block
is necessary or indispensable. Indeed, the novel methods and
systems described herein may be embodied in various forms;
furthermore, various omissions, substitutions, and changes in the
form of the methods and systems described herein may be made
without departing from the spirit of the spirit the inventions
disclosed herein.
