Description
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] The present application claims the benefit of provisional
application No. 61/296,555 filed Jan. 20, 2010, the content of
which is hereby incorporated by reference in its entirety.
BACKGROUND
[0002] The present disclosure relates to a coordinate measuring
machine, and more particularly to a portable articulated arm
coordinate measuring machine having multiple communication
channels.
[0003] Portable articulated arm coordinate measuring machines
(AACMMs) have found widespread use in the manufacturing or
production of parts where there is a need to rapidly and accurately
verify the dimensions of the part during various stages of the
manufacturing or production (e.g., machining) of the part. Portable
AACMMs represent a vast improvement over known stationary or fixed,
cost-intensive and relatively difficult to use measurement
installations, particularly in the amount of time it takes to
perform dimensional measurements of relatively complex parts.
Typically, a user of a portable AACMM simply guides a probe along
the surface of the part or object to be measured. The measurement
data are then recorded and provided to the user. In some cases, the
data are provided to the user in visual form, for example,
three-dimensional (3-D) form on a computer screen. In other cases,
the data are provided to the user in numeric form, for example when
measuring the diameter of a hole, the text "Diameter=1.0034" is
displayed on a computer screen.
[0004] An example of a prior art portable articulated arm CMM is
disclosed in commonly assigned U.S. Pat. No. 5,402,582 ('582),
which is incorporated herein by reference in its entirety. The '582
patent discloses a 3-D measuring system comprised of a
manually-operated articulated arm CMM having a support base on one
end and a measurement probe at the other end. Commonly assigned
U.S. Pat. No. 5,611,147 ('147), which is incorporated herein by
reference in its entirety, discloses a similar articulated arm CMM.
In the '147 patent, the articulated arm CMM includes a number of
features including an additional rotational axis at the probe end,
thereby providing for an arm with either a two-two-two or a
two-two-three axis configuration (the latter case being a seven
axis arm).
[0005] Contemporary portable AACMMs are typically controlled by an
external computer processor that is physically connected to the
AACMM to configure and connect the AACMM to a network. While
existing portable AACMMs are suitable for their intended purposes,
a portable AACMM that includes logic to connect to a network would
enhance portability and ease of use of the portable AACMM.
SUMMARY OF THE INVENTION
[0006] An embodiment is a portable articulated arm coordinate
measurement machine (AACMM) that includes a manually positionable
articulated arm portion having opposed first and second ends, the
arm portion including a plurality of connected arm segments, each
of the arm segments including at least one position transducer for
producing a position signal. The portable AACMM also includes a
measurement device attached to a first end of the portable AACMM
and a plurality of communication channels. The portable AACMM also
includes an electronic circuit for receiving the position signals
from the transducers and for providing data corresponding to a
position of the measurement device. The portable AACMM also
includes executable by the electronic circuit for receiving a
request from a user to communicate via a selected one of the
plurality of communication channels, and for configuring the
portable AACMM to communicate via the selected communication
channel.
[0007] Another embodiment is a method of implementing a portable
AACMM. The method includes receiving a request from a user to
communicate via a selected communication channel. The receiving is
at the portable AACMM. The portable AACMM includes a manually
positionable articulated arm portion having opposed first and
second ends, the arm portion including a plurality of connected arm
segments, each arm segment including at least one position
transducer for producing a position signal. The portable AACMM also
includes a measurement device attached to a first end of the
portable AACMM, a plurality of communication channels including the
selected communication channel, and an electronic circuit which
receives the position signal from the transducers and provides data
corresponding to a position of the measurement device. The method
also includes configuring the portable AACMM to communicate via the
selected communication channel.
[0008] A further embodiment is a computer program product for
implementing a portable AACMM. The computer program product
includes a storage medium having computer-readable program code
embodied thereon, which when executed by an electronic circuit
located on the AACMM causes the computer to implement a method. The
method includes receiving a request from a user to communicate via
a selected communication channel. The receiving is at the portable
AACMM. The portable AACMM includes a manually positionable
articulated arm portion having opposed first and second ends, the
arm portion including a plurality of connected arm segments, each
arm segment including at least one position transducer for
producing a position signal. The portable AACMM also includes a
measurement device attached to a first end of the portable AACMM, a
plurality of communication channels including the selected
communication channel, and an electronic circuit which receives the
position signal from the transducers and provides data
corresponding to a position of the measurement device. The method
also includes configuring the portable AACMM to communicate via the
selected communication channel.

DETAILED DESCRIPTION
[0021] An embodiment is directed to a portable articulated arm
coordinate measuring machine (AACMM) that includes logic to detect
and connect to available networks. The ability for the portable
AACMM to perform the network connection directly allows the network
connection to be automatically tailored to the portable AACMM.
Having the network connected automatically via the portable AACMM
avoids problems of incorrect system description (e.g., parameters,
hardware specifications, software levels) being entered when
configuring a network connection for a portable AACMM via a device
other than the portable AACMM.
[0022] FIGS. 1A and 1B illustrate, in perspective, a portable
articulated arm coordinate measuring machine (AACMM) 100 according
to various embodiments of the present invention, an articulated arm
being one type of coordinate measuring machine. As shown in FIGS.
1A and 1B, the exemplary AACMM 100 may comprise a six or seven axis
articulated measurement device having a measurement probe housing
102 coupled to an arm portion 104 of the AACMM 100 at one end. The
arm portion 104 comprises a first arm segment 106 coupled to a
second arm segment 108 by a first grouping of bearing cartridges
110 (e.g., two bearing cartridges). A second grouping of bearing
cartridges 112 (e.g., two bearing cartridges) couples the second
arm segment 108 to the measurement probe housing 102. A third
grouping of bearing cartridges 114 (e.g., three bearing cartridges)
couples the first arm segment 106 to a base 116 located at the
other end of the arm portion 104 of the AACMM 100. Each grouping of
bearing cartridges 110, 112, 114 provides for multiple axes of
articulated movement. Also, the measurement probe housing 102 may
comprise the shaft of the seventh axis portion of the AACMM 100
(e.g., a cartridge containing an encoder system that determines
movement of the measurement device, for example a probe 118, in the
seventh axis of the AACMM 100). In use of the AACMM 100, the base
116 is typically affixed to a work surface.
[0023] Each bearing cartridge within each bearing cartridge
grouping 110, 112, 114 typically contains an encoder system (e.g.,
an optical angular encoder system). The encoder system (i.e.,
transducer) provides an indication of the position of the
respective arm segments 106, 108 and corresponding bearing
cartridge groupings 110, 112, 114 that all together provide an
indication of the position of the probe 118 with respect to the
base 116 (and, thus, the position of the object being measured by
the AACMM 100 in a certain frame of reference--for example a local
or global frame of reference). The arm segments 106, 108 may be
made from a suitably rigid material such as but not limited to a
carbon composite material for example. A portable AACMM 100 with
six or seven axes of articulated movement (i.e., degrees of
freedom) provides advantages in allowing the operator to position
the probe 118 in a desired location within a 360.degree. area about
the base 116 while providing an arm portion 104 that may be easily
handled by the operator. However, it should be appreciated that the
illustration of an arm portion 104 having two arm segments 106, 108
is for exemplary purposes, and the claimed invention should not be
so limited. An AACMM 100 may have any number of arm segments
coupled together by bearing cartridges (and, thus, more or less
than six or seven axes of articulated movement or degrees of
freedom).
[0024] The probe 118 is detachably mounted to the measurement probe
housing 102, which is connected to bearing cartridge grouping 112.
A handle 126 is removable with respect to the measurement probe
housing 102 by way of, for example, a quick-connect interface. The
handle 126 may be replaced with another device (e.g., a laser line
probe, a bar code reader), thereby providing advantages in allowing
the operator to use different measurement devices with the same
AACMM 100. In exemplary embodiments, the probe housing 102 houses a
removable probe 118, which is a contacting measurement device and
may have different tips 118 that physically contact the object to
be measured, including, but not limited to: ball, touch-sensitive,
curved and extension type probes. In other embodiments, the
measurement is performed, for example, by a non-contacting device
such as a laser line probe (LLP). In an embodiment, the handle 126
is replaced with the LLP using the quick-connect interface. Other
types of measurement devices may replace the removable handle 126
to provide additional functionality. Examples of such measurement
devices include, but are not limited to, one or more illumination
lights, a temperature sensor, a thermal scanner, a bar code
scanner, a projector, a paint sprayer, a camera, or the like, for
example.
[0025] As shown in FIGS. 1A and 1B, the AACMM 100 includes the
removable handle 126 that provides advantages in allowing
accessories or functionality to be changed without removing the
measurement probe housing 102 from the bearing cartridge grouping
112. As discussed in more detail below with respect to FIG. 2, the
removable handle 126 may also include an electrical connector that
allows electrical power and data to be exchanged with the handle
126 and the corresponding electronics located in the probe end.
[0026] In various embodiments, each grouping of bearing cartridges
110, 112, 114 allows the arm portion 104 of the AACMM 100 to move
about multiple axes of rotation. As mentioned, each bearing
cartridge grouping 110, 112, 114 includes corresponding encoder
systems, such as optical angular encoders for example, that are
each arranged coaxially with the corresponding axis of rotation of,
e.g., the arm segments 106, 108. The optical encoder system detects
rotational (swivel) or transverse (hinge) movement of, e.g., each
one of the arm segments 106, 108 about the corresponding axis and
transmits a signal to an electronic data processing system within
the AACMM 100 as described in more detail herein below. Each
individual raw encoder count is sent separately to the electronic
data processing system as a signal where it is further processed
into measurement data. No position calculator separate from the
AACMM 100 itself (e.g., a serial box) is required, as disclosed in
commonly assigned U.S. Pat. No. 5,402,582 ('582).
[0027] The base 116 may include an attachment device or mounting
device 120. The mounting device 120 allows the AACMM 100 to be
removably mounted to a desired location, such as an inspection
table, a machining center, a wall or the floor for example. In one
embodiment, the base 116 includes a handle portion 122 that
provides a convenient location for the operator to hold the base
116 as the AACMM 100 is being moved. In one embodiment, the base
116 further includes a movable cover portion 124 that folds down to
reveal a user interface, such as a display screen.
[0028] In accordance with an embodiment, the base 116 of the
portable AACMM 100 contains or houses an electronic data processing
system that includes two primary components: a base processing
system that processes the data from the various encoder systems
within the AACMM 100 as well as data representing other arm
parameters to support three-dimensional (3-D) positional
calculations; and a user interface processing system that includes
an on-board operating system, a touch screen display, and resident
application software that allows for relatively complete metrology
functions to be implemented within the AACMM 100 without the need
for connection to an external computer.
[0029] The electronic data processing system in the base 116 may
communicate with the encoder systems, sensors, and other peripheral
hardware located away from the base 116 (e.g., a LLP that can be
mounted to the removable handle 126 on the AACMM 100). The
electronics that support these peripheral hardware devices or
features may be located in each of the bearing cartridge groupings
110, 112, 114 located within the portable AACMM 100.
[0030] FIG. 2 is a block diagram of electronics utilized in an
AACMM 100 in accordance with an embodiment. The embodiment shown in
FIG. 2 includes an electronic data processing system 210 including
a base processor board 204 for implementing the base processing
system, a user interface board 202, a base power board 206 for
providing power, a Bluetooth module 232, and a base tilt board 208.
The user interface board 202 includes a computer processor for
executing application software to perform user interface, display,
and other functions described herein.
[0031] As shown in FIG. 2, the electronic data processing system
210 is in communication with the aforementioned plurality of
encoder systems via one or more arm buses 218. In the embodiment
depicted in FIG. 2, each encoder system generates encoder data and
includes: an encoder arm bus interface 214, an encoder digital
signal processor (DSP) 216, an encoder read head interface 234, and
a temperature sensor 212. Other devices, such as strain sensors,
may be attached to the arm bus 218.
[0032] Also shown in FIG. 2 are probe end electronics 230 that are
in communication with the arm bus 218. The probe end electronics
230 include a probe end DSP 228, a temperature sensor 212, a
handle/LLP interface bus 240 that connects with the handle 126 or
the LLP 242 via the quick-connect interface in an embodiment, and a
probe interface 226. The quick-connect interface allows access by
the handle 126 to the data bus, control lines, and power bus used
by the LLP 242 and other accessories. In an embodiment, the probe
end electronics 230 are located in the measurement probe housing
102 on the AACMM 100. In an embodiment, the handle 126 may be
removed from the quick-connect interface and measurement may be
performed by the laser line probe (LLP) 242 communicating with the
probe end electronics 230 of the AACMM 100 via the handle/LLP
interface bus 240. In an embodiment, the electronic data processing
system 210 is located in the base 116 of the AACMM 100, the probe
end electronics 230 are located in the measurement probe housing
102 of the AACMM 100, and the encoder systems are located in the
bearing cartridge groupings 110, 112, 114. The probe interface 226
may connect with the probe end DSP 228 by any suitable
communications protocol, including commercially-available products
from Maxim Integrated Products, Inc. that embody the 1-Wire.RTM.
communications protocol 236.
[0033] FIG. 3 is a block diagram describing detailed features of
the electronic data processing system 210 of the AACMM 100 in
accordance with an embodiment. In an embodiment, the electronic
data processing system 210 is located in the base 116 of the AACMM
100 and includes the base processor board 204, the user interface
board 202, a base power board 206, a Bluetooth module 232, and a
base tilt module 208.
[0034] In an embodiment shown in FIG. 3, the base processor board
204 includes the various functional blocks illustrated therein. For
example, a base processor function 302 is utilized to support the
collection of measurement data from the AACMM 100 and receives raw
arm data (e.g., encoder system data) via the arm bus 218 and a bus
control module function 308. The memory function 304 stores
programs and static arm configuration data. The base processor
board 204 also includes an external hardware option port function
310 for communicating with any external hardware devices or
accessories such as an LLP 242. A real time clock (RTC) and log
306, a battery pack interface (IF) 316, and a diagnostic port 318
are also included in the functionality in an embodiment of the base
processor board 204 depicted in FIG. 3.
[0035] The base processor board 204 also manages all the wired and
wireless data communication with external (host computer) and
internal (display processor 202) devices. The base processor board
204 has the capability of communicating with an Ethernet network
via an Ethernet function 320 (e.g., using a clock synchronization
standard such as Institute of Electrical and Electronics Engineers
(IEEE) 1588), with a wireless local area network (WLAN) via a LAN
function 322, and with Bluetooth module 232 via a parallel to
serial communications (PSC) function 314. The base processor board
204 also includes a connection to a universal serial bus (USB)
device 312.
[0036] The base processor board 204 transmits and collects raw
measurement data (e.g., encoder system counts, temperature
readings) for processing into measurement data without the need for
any preprocessing, such as disclosed in the serial box of the
aforementioned '582 patent. The base processor 204 sends the
processed data to the display processor 328 on the user interface
board 202 via an RS485 interface (IF) 326. In an embodiment, the
base processor 204 also sends the raw measurement data to an
external computer.
[0037] Turning now to the user interface board 202 in FIG. 3, the
angle and positional data received by the base processor is
utilized by applications executing on the display processor 328 to
provide an autonomous metrology system within the AACMM 100.
Applications may be executed on the display processor 328 to
support functions such as, but not limited to: measurement of
features, guidance and training graphics, remote diagnostics,
temperature corrections, control of various operational features,
connection to various networks, and display of measured objects.
Along with the display processor 328 and a liquid crystal display
(LCD) 338 (e.g., a touch screen LCD) user interface, the user
interface board 202 includes several interface options including a
secure digital (SD) card interface 330, a memory 332, a USB Host
interface 334, a diagnostic port 336, a camera port 340, an
audio/video interface 342, a dial-up/cell modem 344 and a global
positioning system (GPS) port 346.
[0038] The electronic data processing system 210 shown in FIG. 3
also includes a base power board 206 with an environmental recorder
362 for recording environmental data. The base power board 206 also
provides power to the electronic data processing system 210 using
an AC/DC converter 358 and a battery charger control 360. The base
power board 206 communicates with the base processor board 204
using inter-integrated circuit (I2C) serial single ended bus 354 as
well as via a DMA serial peripheral interface (DSPI) 356. The base
power board 206 is connected to a tilt sensor and radio frequency
identification (RFID) module 208 via an input/output (110)
expansion function 364 implemented in the base power board 206.
[0039] Though shown as separate components, in other embodiments
all or a subset of the components may be physically located in
different locations and/or functions combined in different manners
than that shown in FIG. 3. For example, in one embodiment, the base
processor board 204 and the user interface board 202 are combined
into one physical board.
[0040] FIG. 4 illustrates an AACMM system environment in accordance
with an embodiment. The system depicted in FIG. 4 includes a
network 406 in communication with two portable AACMMs 100, a
personal computer 402, and a smart phone 404 (e.g., communicating
with an AACMM 100 via WiFi or Bluetooth). The system depicted in
FIG. 4 also includes a personal computer 402 in direct
communication (i.e., not via a network) with one of the AACMMs 100.
The system depicted in FIG. 4 is intended to be one example of an
AACMM system environment configuration, and is not intended to be
limiting. Another AACMM system environment embodiment includes one
network 406 and one AACMM 100 in communication with the network
406. In other embodiments, any number of portable AACMMs 100 and
user devices (e.g., personal computer 402 and smart phone 404) are
in communication with the network 406.
[0041] In an embodiment, all or a portion of the network 406 is
implemented by a local area network (LAN) or wireless LAN (WLAN).
In another embodiment, all or a portion of the network is
implemented by a personal area network (PAN) using Bluetooth. In a
further embodiment, all or a portion of the network 406 is
implemented by an Ethernet network. It will be appreciated that
network 406 can be implemented by any combination of the
aforementioned networks as well as other types of wired and
wireless networks such as, but not limited to the Internet, and an
intranet.
[0042] In an embodiment, the portable AACMMs 100 and user devices
(e.g., personal computers 402 and smart phone 404) are located in
the same geographical location. In another embodiment, the portable
AACMMs 100 and the user devices are located in two or more
different geographical locations. It will be appreciated that the
user devices are not limited to personal computers and cellular
telephones but that they include any device capable of
communicating with a network such as, but not limited to personal
digital assistants (PDAs), and net book computers.
[0043] The user devices (e.g., the personal computer 402 and smart
phone 404) access the processor 302 on the base processor board 204
in an AACMM 100 to request the AACMM 100 to perform user selected
functions. Thus, user devices can be used in a fashion similar to
the user interface board 202 to interface with the base processor
board 204 of the AACMM 100. Depending on how the user device is
communicating with the AACMM 100, all, a portion, or none of the
code located on the user interface board 202 and the base processor
board 204 may be resident on the user device. Some applications may
also be remote (accessing the AACMM 100 via a router) and present
in a different network.
[0044] An application residing on a user device may be used to
perform all or a subset of the functions of the user interface
board 202. In an embodiment, an application written for a specific
user device resides on the user device, and this application
collects data from the AACMM 100 and uses it in the application
resident on the user device. This approach of having the
application written for a specific user device requires that a
custom version of the application be developed for each type of
user device (e.g., I-Phone, Android, Windows CE, etc.).
[0045] In another embodiment, an application resides in the AACMM
100, and the user accesses the application and data via a web-like
interface. In this case, the AACMM 100 hosts a web service version
of the application via any standard browser on a remote user
device.
[0046] In response to the user selected function requests, various
components, e.g., encoders, sensors, and electronics are activated
and collect data responsive to the request. In response to other
user selected function requests, the AACMM 100 and/or user
interfaces associated with the AACMM 100 are configured. In one
embodiment, any user selected function that can be initiated or
accessed via the LCD 338 on the user interface board 202 can also
be initiated or accessed via a user device connected to the AACMM
100 via the network 406. In another embodiment, certain user
selected functions are designated as those that can be accessed via
a user device connected to the AACMM 100 via the network. In
another embodiment, a combination of these two approaches is
implemented, with some user selected functions being automatically
accessible via a user device and other user selected functions
requiring authorization to communicate with a user device.
[0047] User selected functions that may be initiated by a user
device and executed by the processor 302 on the base processor
board 204 include, but are not limited to: acquisition of
dimensional measurements of an object, monitoring various
temperature values, performing calibration of one or more
components of the AACMM 100, performing diagnostics on one or more
of the components of the AACMM 100, and providing training
guidance.
[0048] FIG. 5 illustrates a main menu user interface screen in
accordance with an embodiment. In an embodiment, the user interface
screen depicted in FIG. 5 is displayed on the LCD 338 on the user
interface board 202. In an embodiment, the user interface board 202
includes resident applications (e.g., stored in the memory 332) and
executed by the display processor 328 for providing a graphical
user interface (GUI) with selectable menu options corresponding to
the available functions implemented by the AACMM 100. The GUI may
be implemented as a set of menu options, such as those shown in
FIG. 5. In FIG. 5, a computer screen window of the LCD 338
illustrates various menu options, such as "Part Setup" (e.g., for
specifying part elements such as planes, lines, circles, and
cylinders), "Measure" (e.g., for specifying features, lengths,
angles, and positions), "Files" (e.g., for defining new parts,
loading macros, and transferring data), "Settings" (e.g., for
specifying applications, network connections, display
characteristics, sound elements, power parameters, and languages),
and "Diagnostics". In an embodiment, a user selects "Settings"
(e.g., by touching the screen on the LCS 338) in order to get
status about or to set up the network connection(s).
[0049] FIG. 6 illustrates a settings menu user interface screen in
accordance with an embodiment that is displayed when the user
selects "Settings" on the main menu user interface screen depicted
in FIG. 5. In an embodiment, the user selects "Connection" in order
to get status about or to set up the network connection(s).
[0050] FIG. 7 illustrates a network connection user interface
screen in accordance with an embodiment that is displayed when the
user selects "Connection" on the setting menu user interface
depicted in FIG. 6. The network connection user interface screen
depicted in FIG. 7 allows a user to select what communication
options are to be turned on or off. As shown in FIG. 7, Bluetooth
is enabled (turned on), as well as Ethernet. Also as shown in FIG.
7, a WiFi network is not currently enabled (it is turned off) on
the AACMM 100. In an embodiment, the user changes the status by
selecting a network icon. For example, the status of Bluetooth can
be changed from "enabled" to "not enabled" by clicking on the
Bluetooth icon on the network connection user interface screen
shown in FIG. 7.
[0051] FIG. 8 illustrates a communications setting user interface
screen for a WiFi network in accordance with an embodiment. In the
user interface screen shown in FIG. 8, the WiFi network has been
selected (as indicated by check mark next to the WiFi enabled box).
The user interface screen presents the user with options for
setting up a WiFi connection: to connect the AACMM 100 to an
Ethernet network (e.g., a LAN), to a network (e.g., the Internet),
and/or directly to a personal computer or laptop computer without
going through a network. As shown in FIG. 8, the WiFi connection
can be established (and an address for the AACMM 100 assigned) via
a dynamic host configuration protocol (DHCP) or via a static
internet protocol (IP). The way that the WiFi connection is
established is installation dependent, and embodiments of the AACMM
100 described herein can support both DHCP and a static IP.
[0052] FIG. 9 illustrates a configure static IP user interface
screen that is presented to a user when the user selects a static
IP connection on the communications setting user interface screen
shown in FIG. 8. As shown in the embodiment in FIG. 9, the user
enters an IP address, a subnet mask and a gateway to establish a
static IP WiFi connection to the network or to the Ethernet.
[0053] FIG. 10 illustrates an access point connection user
interface screen in accordance with an embodiment when a user has
selected a WiFi network connection on the user interface shown in
FIG. 7. When the WiFi network connection is selected, the AACMM 100
looks for wireless routers and then displays the names of the WiFi
networks associated with the located routers on a user interface
screen such as the one shown in FIG. 10. The user interface screen
shown in FIG. 10 also includes the signal strength as indicated by
the length of the line next to each identified network. The user
can then select one or more of the wireless networks and the AACMM
100 will automatically connect to the selected networks. In an
embodiment, the AACMM 100 can only connect to one router at a time.
In an embodiment, where Bluetooth and Ethernet are considered
separate networks, both of these channels are open at the same
time. In an embodiment, the AACMM 100 is a slave device on a
network, and the network router and other devices are master
devices.
[0054] In an embodiment, the user interface screens shown in FIGS.
5-10 are displayed on the LCD 338 located on the user interface
board 202. In another embodiment, all or a subset of the user
interface screens shown in FIGS. 5-10 are displayed on a user
device that is in communication with the portable AACMM 100 via a
network 406. In other embodiments, the content and the layout of
the user interface screens shown are different than that shown in
FIGS. 5-10, as the user interface screens shown in FIGS. 5-10 are
intended to be examples of one way that a portable AACMM 100 may be
connected to a network.
[0055] FIG. 11 illustrates a process flow for configuring network
connections for a portable AACMM 100 in accordance with an
embodiment. In an embodiment, the process flow depicted in FIG. 11
is executed by processor 302 located on the base processor board
204 of the AACMM 100. In an embodiment, the processor 302 outputs
to and receives input from the LCD 338 via the display processor
328 on the user interface board 202. At step 1102, one or more of
the communication channels supported by the AACMM 100 (e.g., USB,
Ethernet, Wifi, Bluetooth) are selected. At step 1104 it is
determined if a USB connection has been selected. If a USB
connection has been selected, then step 1106 is performed and a USB
cable is plugged in to the AACMM 100 and external host (computer),
at which time the external host enumerates the ACCMM (discovers and
loads the required computer software driver for the ACCMM) and an
application is executed. In an embodiment, the discovery and
loading of the AACMM driver takes place automatically. In the
embodiment depicted in FIG. 11, processing is completed after step
1106. In another embodiment, after step 1106 is completed
processing continues at step 1108.
[0056] If the USB communication channel was not selected, then step
1108 is performed to set up the supported communication channels.
External network(s) corresponding to the selected communication
channel (s) is configured. In an embodiment, the external network
is one of a LAN, a WLAN, or a PAN. In addition, any computers
and/or peripherals used by the communication channel are configured
at step 1108. At step 1110, a user selects one or more of the
communication channels from a user interface screen such as the one
in FIG. 7. At step 1112, the AACMM is configured to communicate
with the selected communication channel(s).
[0057] Technical effects and benefits include having a large
variety of communication technologies supported such that the user
has maximum flexibility in using the product in an environment
where restrictions may be placed on one or more of the typical
communication options. As examples, in some plants, Bluetooth is
used to control automated delivery systems, thus Wi-Fi must be used
to avoid interference. In another, Wi-Fi has too great a range and
thus Bluetooth is preferable. In another, wireless methods are not
acceptable due to the classified nature of the parts, thus wired
Ethernet is required. In a plant with network restriction on
network access, USB is required. All of these options are supported
in exemplary embodiments described herein.
[0058] As will be appreciated by one skilled in the art, aspects of
the present invention may be embodied as a system, method, or
computer program product. Accordingly, aspects of the present
invention may take the form of an entirely hardware embodiment, an
entirely software embodiment (including firmware, resident
software, micro-code, etc.) or an embodiment combining software and
hardware aspects that may all generally be referred to herein as a
"circuit," "module" or "system." Furthermore, aspects of the
present invention may take the form of a computer program product
embodied in one or more computer readable medium(s) having computer
readable program code embodied thereon.
[0059] Any combination of one or more computer readable medium(s)
may be utilized. The computer readable medium may be a computer
readable signal medium or a computer readable storage medium. A
computer readable storage medium may be, for example, but not

programming language such as Java, Smalltalk, C++, C# or the like
and conventional procedural programming languages, such as the "C"
programming language or similar programming languages. The program
code may execute entirely on the user's computer, partly on the
user's computer, as a stand-alone software package, partly on the
user's computer and partly on a remote computer or entirely on the
remote computer or server. In the latter scenario, the remote
computer may be connected to the user's computer through any type
of network, including a local area network (LAN) or a wide area
network (WAN), or the connection may be made to an external
computer (for example, through the Internet using an Internet
Service Provider).
[0063] Aspects of the present invention are described with
reference to flowchart illustrations and/or block diagrams of
methods, apparatus (systems) and computer program products
according to embodiments of the invention. It will be understood
that each block of the flowchart illustrations and/or block
diagrams, and combinations of blocks in the flowchart illustrations
and/or block diagrams, may be implemented by computer program
instructions.
[0064] These computer program instructions may be provided to a
processor of a general purpose computer, special purpose computer,
or other programmable data processing apparatus to produce a
machine, such that the instructions, which execute via the
processor of the computer or other programmable data processing
apparatus, create means for implementing the functions/acts
specified in the flowchart and/or block diagram block or blocks.
These computer program instructions may also be stored in a
computer readable medium that may direct a computer, other
programmable data processing apparatus, or other devices to
function in a particular manner, such that the instructions stored
in the computer readable medium produce an article of manufacture
including instructions which implement the function/act specified
in the flowchart and/or block diagram block or blocks.
[0065] The computer program instructions may also be loaded onto a

devices to cause a series of operational steps to be performed on
the computer, other programmable apparatus or other devices to
produce a computer implemented process such that the instructions
which execute on the computer or other programmable apparatus
provide processes for implementing the functions/acts specified in
the flowchart and/or block diagram block or blocks.
[0066] The flowchart and block diagrams in the Figures illustrate
the architecture, functionality, and operation of possible
implementations of systems, methods, and computer program products
according to various embodiments of the present invention. In this
regard, each block in the flowchart or block diagrams may represent
a module, segment, or portion of code, which comprises one or more
executable instructions for implementing the specified logical
function(s). It should also be noted that, in some alternative
implementations, the functions noted in the block may occur out of
the order noted in the Figures. For example, two blocks shown in
succession may, in fact, be executed substantially concurrently, or
the blocks may sometimes be executed in the reverse order,
depending upon the functionality involved. It will also be noted
that each block of the block diagrams and/or flowchart
illustration, and combinations of blocks in the block diagrams
and/or flowchart illustration, may be implemented by special
purpose hardware-based systems that perform the specified functions
or acts, or combinations of special purpose hardware and computer
instructions.
