Description
RELATED INFORMATION
[0001] This patent application is a divisional of co-pending patent
application Ser. No. 09/420,459 filed on Oct. 18, 1999. The
priority of patent application Ser. No. 09/420,459 is expressly
claimed, and the disclosure of the prior application is hereby
incorporated by reference in its entirety.
FIELD OF THE INVENTION
[0002] The present invention is directed to wireless
communications, and more particularly to image capture by portable
wireless communications products and wireless transmission of data
related to the image to a remote location.
BACKGROUND OF THE INVENTION
[0003] Ornamental designs that incorporate digital cameras with
cellular telephones and a portable computer into a single housing
are known in the art. One example of such a design is shown in U.S.
Pat. Des. No. 405,457 issued Feb. 9, 1999, to Kawashima. A cellular
telephone is illustrated essentially affixed to the side of a
digital camcorder with each unit interfaced to a central processor,
yet for all purposes, each component operates independently of the
other. This design is deficient in that the capabilities of the
three identified components are not functionally integrated and
each is unable to take advantage of the features and benefits of
the others. Another example is found in U.S. Pat. No. 5,917,542
issued Jun. 29, 1999, to Moghadam, et al., which refers to a system
and method for digital image capture and transmission. A digital
camera containing a short term and long term memory capability is
combined with a wireless communication means for transmitting
individually captured digital images. The design is effective in
determining signal strength and assuring successful transmission of
an image, but deficient in that the device does not provide the
capabilities of automatic identification, voice communication, or
other interactive business functions. Other examples of the
wireless transmission of video images are also known in the art. In
U.S. Pat. No. 4,884,132 issued Nov. 28, 1989 to Morris, et al., a
security camera is disclosed that captures images and relays those
images to remote stations via wireless transmission. However, the
Morris patent is directed to the transmission of video images and
does not provide users with a range of complementary
functionality.
[0004] Numerous examples exist showing various portable computer
terminals; some with integrated communication means and a means for
reading bar codes. These terminals include large on-board memory
capacity, allow for the reading of bar codes and subsequent
wireless transmission of the decoded information to a remote site.
These terminals are deficient in that they are dedicated to the art
of automatic identification and do not provide for the cumulative
capability of automatic identification, two-way voice
communication, transmission of instantly captured digital images,
and the conduct of electronic commerce and personal finance
activities, and the advantages appurtenant to such a
combination.
[0005] Methods for augmenting the functionality of mobile
telephones are also known in the art. U.S. Pat. No. 5,887,266
issued Mar. 23, 1999 to Heinonen, et al., discloses a method for
using applications in a mobile station. The method requires an
application-bearing module, such as a removable PCMCIA memory card,
to be physically inserted into and connected with the mobile
station or telephone. The application software is then allow ed to
interact with the mobile station operating system to execute the
application. Through this, the on-board memory capacity of the
mobile station is effectively increased to allow the inclusion of
application software. Unfortunately, this technique also limits the
number of applications, and the size of the applications, to only
those that can reside fully within the capacity of the removable
memory card.
[0006] Remote access to or from networked computers is also known
in the art. U.S. Pat. No. 5,544,320 issued Aug. 6, 1996, to Konrad
refers to a system for access to remote information services.
Employed is the concept of distributed processing wherein the
architecture specifically avoids providing functionality to a
component that is the primary responsibility of another component
and, specifically, envisions that the local host be a local
multi-user computer system, a workstation, or a Personal Computer.
The disclosed design and architecture precludes user mobility,
requires significant computer memory, processing power, detailed
user input, and a wired telecommunications interface resident at
the local host. In U.S. Pat. No. 5,790,977 issued Aug. 4, 1998, to
Ezekiel, a host computer system is provided containing access to a
remote instrument. In response to a request from the control and
data acquisition software running on the host system, data acquired
by the remote instrument is forwarded to the host system. This
system is deficient in that the remote data acquisition instrument
acts as a single purpose slave device unable to perform multiple
applications or serve as a means of independently activating
functions resident on the remote host computer system.
OBJECTS AND SUMMARY OF THE INVENTION
[0007] It is, therefore, an object of the present invention to
overcome the above deficiencies of the prior art and provide users
of wireless telecommunications technology an enhanced utility and
functionality without diminishing or altering the original
capabilities of the host portable two-way communication device.
[0008] Broadly, the present invention is directed to a
self-contained integrated imaging module, which is designed to be
incorporated into any number of portable host products and which
enables users of these products to "see," "speak," "show" images,
and securely exchange personal or business information with other
people and computers. Suitable host products include, but are not
limited to, cellular/satellite telephones, wireless empowered
Personal Digital Assistants (PDA), portable computers, portable
automatic identification terminals, and the like. Miniaturized
two-way portable communication devices are preferred. The
integrated imaging module preferably includes, among other things,
a fully integrated semiconductor device, such as a Complementary
Metal-Oxide Semiconductor (CMOS), which enhances host product
productivity and capability by allowing users to execute remotely
virtually any function. By use of such an integrated imaging
module, one can convert an instant personal objective into a
machine executable action at a remote location, which may be
physically distant or proximate to the user at the time of
execution.
[0009] Among the productivity and capability enhancements obtained
by the present invention are one or more of the following: [0010]
1. enabling distributed and/or parallel processing of multiple
applications within the host product; [0011] 2. providing the
functions of still and full-motion image capture and processing;
[0012] 3. automatic identification decoding capability employing
imaging means; [0013] 4. secure storage of personal information
such as credit/debit card numbers; [0014] 5. biometric verification
as a gate to access personal database information; [0015] 6.
execution of personal financial transactions; [0016] 7. wireless
interface protocols for peripheral devices, the Internet and other
networked computer systems; and [0017] 8. optimally formatted
images and textual information in preparation for two-way
transmission via wireless means.
[0018] Advantageously, the integrated imaging module of the present
invention adds such features, functionalities, and capabilities
without diminishing the available memory, computing performance, or
previously existing functionality of the host product.
[0019] The resultant portable communications product, enhanced by
the integrated imaging module (also referred to herein as the
"module") in accordance with a preferred embodiment of the
invention, is able to provide users with the following variety of
structures implementing the above-noted functions.
[0020] A remote voice and/or data communications interface
capability via a wireless communication channel to a networked
computer server, such as by using a cellular telephone and/or
satellite network telephone. This includes the ability to receive
television or other digital image broadcasts from, for example,
corporate or private wide-area and local-area networks, or the
Internet.
[0021] Another implementation is to provide remote activation or
initiation of functions on computer peripherals, distant servers,
or consumer appliances, preferably in a secure manner, whereby only
authenticated individuals can execute such functions, thereby
achieving a distributed processing function. Preferably, the module
can also provide for the generation of a unique digital
security/authentication code, such as an electronic or digital
signature, or a digital token or the like. Such a code can then be
transmitted along with a resource locator address to a remote
server computer to provide the user with access to certain
application software, data or remote control of a remote device.
The latter is optionally achieved after the user's identity is
authenticated or an access code or personal identification code is
identified. Data transmissions may be in an encrypted or
non-encrypted format, with the module or host device on the one
hand, and the remote device on the other hand, having suitable
encryption/decryption functionalities.
[0022] Another implementation is to provide a secure memory mode of
operation. In this, the module contains personal identification
data including, for example, credit card/debit card account
information, bank account, driver's license number, social security
number and the like for executing securely financial transactions.
In this regard, the module enhanced product allows the user to
execute a secure purchase of non-electronic commerce goods and
services.
[0023] An alternate and preferred embodiment of a secure memory
mode implementation also provides for biometric
verification/authentication as a gate for accessing and
subsequently authorizing transmission of personal data related to
financial transactions. Biometric verification also can provide for
other secure functions, e.g., access to secret or hidden computer
files. If the correct biometric or authentication information is
not provided, access to the personal data is denied.
[0024] Another implementation of the module is to provide an
imaging means to automatically scan, decode, and transmit, via
wireless communication networks, information encoded in bar codes
and other automatic identification indicia, including Optical
Character Recognition (OCR).
[0025] Still another implementation is to provide an interface to
and exchange information with Smart Cards and Radio Frequency
Identification Tags (RFID).
[0026] A further implementation is to provide capture of a single
digital image or sequential digital images and to transmit the same
via a wireless communication channel to a remote location. This can
be for purposes of remote storage or forwarding of the captured
image, or the participation in video teleconferences in real
time.
[0027] Thus, the device of the present invention is preferably able
to transmit queries, receive textual and graphic responses, execute
secure purchase of goods or services, and remotely store records
related to electronic commerce transactions
[0028] As will be understood by a person of ordinary skill in the
art, the functions and capabilities of the device may be activated
via the use of physical buttons on a keypad, electronic buttons or
menus on a display screen, automatic data sensing, or voice
activated commands, as deemed suitable or as may be available with
the host product.
[0029] In another embodiment, a "car kit" is provided as part of a
system including the integrated imaging module enhanced host
product. In this embodiment, the car kit incorporates a relatively
large-size display screen, suitable for viewing downloaded map
images while driving and for displaying an alphanumeric keyboard
image or icon graphic user interface for touch-sensitive data
entry. In this regard, the car kit features are preferably
activated when a portable two-way communication device
incorporating the integrated imaging module is placed in a
complementary holder adapted to interface with the communication
device and thus provide an auxiliary input and display.
[0030] The open system architecture and interface protocols similar
to that of U.S. Pat. No. 5,809,415 issued Sep. 15, 1998, to
Rossmann are generally known to persons skilled in the art and may
be used to facilitate generalized wireless access to secure remote
closed-system entry nodes. This transmission protocol, used in
conjunction with the features and benefits of the imaging module
herein disclosed, provides a multi-layered security procedure that
ensures each transmission is from an authorized portable two-way
communication device, and that the activating user is indeed the
authorized individual. Once the user is authenticated, access to
the remote closed system is granted, thereby completing the
communications link. As a result, the portable communications
device is empowered with the memory, speed, processing power, and
application functionality of every computer within the remote
closed system (e.g., a network).
[0031] Through this architecture, which is believed to be within
the abilities of a person of ordinary skill in the art to
construct, the holder of each portable two-way communication
device, enhanced with the imaging module in accordance with the
present invention, has available--preferably in their hand in a
miniature device--every database and productivity enhancing
software system resident on any network throughout the world. The
reference to a "miniature" device is to include such conveniently
portable items as cellular telephones, personal digital assistants,
portable computer terminals, and the like.
BRIEF DESCRIPTION OF THE DRAWINGS
[0032] These and other advantages, features, and characteristics of
the invention will become apparent to a person of ordinary skill in
the art in view of the following detailed discussion of preferred

accompanying drawings, in which like reference characters refer to
like elements, and in which:

DETAILED DESCRIPTION OF THE INVENTION
[0036] With reference to FIG. 1, the integrated imaging module 100
of the present invention, is fully self-contained and requires a
host portable communications device 120 to supply only an interface
122 and power (not shown). The interface 122 and power can be
conveyed to the integrated imaging module 100 either via an
internal bus connection to a host device controller board (not
shown) or via an external RS232 port of the host (not shown).
Module 100 includes a lens assembly 102, which may be comprised of
either a single fixed lens, or multiple fixed, extendable, or
moveable lens elements. Lens assembly 102 is preferably placed
forward of a multi-layered semiconductor device 130. The
semiconductor device 130, preferably constructed as a Complementary
Metal-Oxide Semiconductor (CMOS) integrated component, has an image
sensor layer 103, an automatic identification layer 104, a personal
database layer 105, a biometric access layer 106, a central
procession unit layer 107, and optionally a memory layer 108 (shown
in phantom lines in FIG. 1).
[0037] Layer 103 contains an imaging sensor disposed external to
the die. Image sensor 103 is conventionally comprised of multiple
light sensitive pixels capable of discerning light intensity, and
an integrated image processing circuit which converts the analog
values of reflected light intensity from each pixel into instant
digital values. The digital values are then collected and stored,
e.g., in memory 108, to correspond to the spatial image sensed by
the imager sensor 103. This creates a machine-understandable
digital image.
[0038] The captured digital image may then be interrogated or
processed based on a user-selected command, as appropriate to the
desired application. Digital images may be transferred singly or in
rapid succession via input/output means 110 to the host device 120
for wireless transmission to a remote location, or retained for
processing. Automatic identification layer 104 may be invoked and
executed to process the captured digital image to determine the
presence of automatic identification indicia within the digital
image. If automatic indicia are found, the information contained
therein can then be decoded and transferred to the host device 120
via input/output means 110 for display and/or wireless
transmission. In addition, the automatic indicia could enable the
host device 120 to execute an application that requires an
authorized input code, for example, a coded employee identification
card to enable wireless communications.
[0039] Also included in device 130 is layer 105 which is a secure
memory area designed to contain the user's sensitive personal
information, such as credit card and debit card account numbers,
bank checking account numbers, social security numbers, passwords,
etc. Access to layer 105 may only be achieved after first passing
through an authentication gate, for example, layer 104 as described
above or layer 106. In this regard, layer 106 is a secure memory
area designed to contain user-specific biometric data, such as
digital values related to fingerprint minutia, retina scans, voice
prints, DNA or, conceivably, another form of complex Personal
Identification Code ("PIN"). Preferably, once layer 106 is
initialized, neither it nor the information contained in layer 105
can be changed or accessed without a subsequent identical match. In
the event someone attempts to alter the data contained in layer
106, without first scanning or keying an identical match, the
information contained in layer 105 can be automatically be locked
or erased. For example, a failure to match may lock layer 106 for a
given time and multiple failures to match in succession during a
given time period may cause erasure. Further, any time personal
data from layer 105 is transmitted it will be accompanied by, and
encrypted with or authenticated by, the biometric "image" entered
by the user and validated by the reference data contained in layer
106. In this manner, the receiving communication node can also
validate both the incoming account information and the biometric
image of the initiating user within its own database by decoding
the encrypted biometric image or by verifying the authenticity of
the transmitted data. For example, authentication may occur using
well known digital signatures made of a hash of the biometric data,
and regenerating the hash and comparing it to the transmitted hash
to establish authenticity. It should be understood that the
reference to biometric "image" is a broad reference that includes
both graphic images and electronic data corresponding to, but not
actually generating, such an image. In the case that the biometric
image received does not match the reference biometric image, the
received image can be stored, flagged, transmitted to a remote
device (e.g., an FBI computer) and used later to search law
enforcement biometric databases for the actual identity of the
individual initiating the potentially fraudulent transaction.
Similarly, if the biometric image cannot be authenticated, the
received data can be saved and used to track the fraudulent user.
Referring to the central processing layer 107, it provides general
purpose processing capability for interpreting and executing
commands between the host device and the integrated imaging module,
manipulating data, executing digital zoom algorithms, and providing
additional intelligence and processing power for implementing
wireless interface protocols and Internet message formatting.
[0040] Various wireless protocol libraries, Internet browsers,
menus, and other non-sensitive data can be stored in memory layer
108 or alternately or in addition, in a supplemental memory 109.
Memory layer 108 and supplemental memory 109 (collectively
"memory") also may serve as a transmission storage buffer, as
necessary, during wireless transmission of large image or data
files by or to the host device 120.
[0041] Referring to FIG. 2, an integrated imaging module 100 is
preferably incorporated within or as part of host device 120, which
is illustrated as a portable wireless communications device 220
using an internal electronic bus connection 222. Portable wireless
communications device 220 may be, for example, cellular or
satellite telephones, such as a Nokia model 9000i1 or a NeoPoint
model 1000; a wireless empowered Personal Digital Assistant (PDA)
such as a 3Com Palm model Pilot III, IV, V, VII or like devices; a
wireless empowered portable computer such as a Compaq Presario,
Sony Vario, Apple PowerBook and the like; a portable automatic
identification terminal such as a Telxon PTC-960LE or a Symbol
Technologies SPT 1700; or the like. Imaging module 100, as more
fully described with reference to FIG. 1, is connected to portable
wireless communications product 220 via a high-speed electronic bus
222 to host device controller board 207. Power to imaging module
100, as well as the exchange of instructions and data, are
accomplished via this connection point.
[0042] Device 220 functions may be activated either by voice
command via microphone 213, touch screen display 214, input pad
215, or scanning an automatic identification indicia 217
instruction set employing module 100. Display screen 214 also may
be used to present visual output responses processed or received by
the device 220, and input handwritten or typed messages, symbols
and signatures. A user may selectively activate a wireless
connection to one of the many nodes 218 or choose a function within
device 220 that, in turn, will automatically activate a
connection.
[0043] In an application where the user is making a purchase, for
example, as discussed in more detail below, the value of the
proposed purchase can be determined either by optically scanning
and interpreting automatic indicia 217 printed on or adjacent to
the product, or on a cash register receipt, or by manually
inputting the amount via touch screen 214 or input pad 215. The
user would then scan a biometric attribute, such as a fingerprint
or retina on biometric pad 216 or display 214, reenter a
comparative voice print in microphone 213, or the like, and
initiate a comparison to the biometric reference data contained in
layer 106 of semiconductor device 130.
[0044] If an identical match is made or authenticated, processor
layer 107 will extract the credit or debit account information
stored in layer 105, and combine it with the digital values of the
biometric attribute then entered by the user, along with the amount
being charged, forming an integrated message. The integrated
message is then returned to controller 207, along with a telephone
number or Internet web address of the associated financial
institution. Controller 207 also manages encryption (and
decryption) of the data to be transmitted where appropriate.
Controller 207 then forwards the message to a transmitter 210 for
broadcast via cellular/satellite network node 219 directly or (via
the Internet node 220 to the financial institution (See node 303g
of FIG. 3). The financial institution node will then validate the
user (typically employing the biometric attribute provided by the
user as found in the integrated message) and account information
received, validate instant credit worthiness, and accept or reject
the transaction.
[0045] If the transaction is accepted, a debit is charged to the
user's account and a credit is forwarded to the merchant's account
with a transaction completion message being generated, forwarded
and displayed on the merchant's local in-store terminal.
Simultaneously, a user transaction identification record is
generated and retained within the user's financial file at the
financial institution and a message can be returned to the user via
receiver 211 and display 214 (or audibly displayed via speaker 212
if so desired). If the transaction is rejected, however, a message
so indicating is returned to both the merchant and the user. The
message to the user could include a specific reason for the
rejection and be viewed privately on display 214. If the
transaction is rejected because the user could not be properly
validated, the fingerprint data conveyed with the purchase request
can be retained by the financial institution for later use by law
enforcement to determine the true identity of the unauthorized
requester. Further, the device 220 could be programmed to start a
distinctive beeping indicating that a fraudulent transaction was
attempted.
[0046] In an application where a user wishes to take a picture, a
"Photo" option from a text or graphic menu displayed on portable
wireless communications device 220 can be selected. This selection
activates a command from controller 207 to semiconductor module 130
that, in turn, activates analog to digital processing of the
reflected light being sensed by layer 103. Additionally, a wireless
communication connection is made via network node 219 or Internet
node 220 to an e-mail address or other networked repository. A
subset of the pixel values sensed by layer 103 are captured and
conveyed by processor layer 107 via input/output means 110 to
controller board 207, causing a less than full resolution image to
be displayed in real-time on display 214. Display 214 now functions
as an imaging viewfinder for a digital camera function. Once the
user frames the image to be captured, a button is depressed on
input pad 215, or elsewhere on device 220, causing the instant
digital image to be momentarily frozen on display 214 and causing
the corresponding full resolution image to be stored in memory,
preferably supplemental memory 109.
[0047] Processor layer 107 may now begin transferring either the
full resolution image or a compressed version of the image, in a
format such as JPEG or MPEG, to controller 207 and transmitter 210
for wireless broadcast. Controller 207 will interact with processor
layer 107 to ensure that the rate of transfer from memory 109
corresponds to the rate at which transmitter 210 is able to
broadcast. Once the image has been successfully broadcast and
received, a suitable message can be returned from the network
repository to device 220 for audio and/or visual display to the
user. One preferred such message is to cause a file message to be
superimposed over the image on display 214 indicating that "upload
is complete." The user then may forward the already uploaded image
to yet another web site, download the image back to device 220 for
viewing on display 214, and/or retransmit the image to a local
computer peripheral via an infrared transmitter contained in
external port 208, or delete the image entirely.
[0048] If a user wishes to access the capabilities of the Internet,
the "Browser" function is selected from the portable communications
device 220 menu alternatives. This selection activates a command
from controller 207 to layer 107 of semiconductor device 130. Layer
107 will cause the browser menus and command structure to be
activated from memory layer 108 and/or supplementary memory 109 and
the Internet menu options presented on display 214 via controller
207.
[0049] Simultaneously, a wireless communications link is
established via controller 207 and transmitter 210 to the user's
pre-selected Internet service provider node 220.
[0050] In an implementation in which the user is shopping and
wishes to compare item prices, the user may either enter the
narrative description of the manufacturer and item of interest or
scan the item identification code (e.g., a UPC) as contained in an
automatic identification indicia. If scanning automatic
identification indicia 217, the user would select the "Scan" option
from a menu displayed on device 220, that would immediately
activate the display screen viewfinder function as described above
for the "Photo Menu Option." The user would then direct integrated
imaging module 100 toward the automatic identification indicia 217,
framing the indicia within the viewfinder, i.e., the display 214.
Once in the field of view, the user would activate a button or
other input on device 220, thereby capturing a digital image of the
area containing the indicia 217.
[0051] Automatic identification layer 104 of semiconductor device
130 would then be invoked, causing a digital search of the stored
image in an effort to locate any form of indicia therein. Any
indicia 217 so located would be decoded and the information
contained within the indicia would be displayed on display 214. If
multiple symbols were decoded, the user may highlight the
information desired to be compared and depress the "Send" key
(e.g., a button) of device 220. This action will cause the
highlighted information to be forwarded by controller 207 to
transmitter 210 for wireless broadcast to the connected Internet
web site. Once received at the web site node 220, an Internet-wide
search could be conducted for the identical item number, a list
compiled, and the compiled list returned via receiver 211 and
controller 206 to display screen 214. Additionally, the returned
information could include the location of alternative stores that
carry the same product within an n-mile radius of the user's
present location, where "n" is a user selected distance. This can
be accomplished either by a circuit, which cooperates with the
Global Positioning System, that may be in or incorporated into
device 220, or by determining the geographic location of the first
relay tower used in the transmission by the user's network operator
node 219.
[0052] Referring to FIG. 3, a functional system architecture is
disclosed wherein a miniature portable two-way communication device
320 transmits via wireless transmission channel 302 digital signals
representing voice, data, biometric values, and/or digital images.
Digital signal 302 is received selectively by communications node
303 and, in response to a command structure contained within
digital signal 302, initiates appropriately an activity or function
304. Upon completion of the user-selected activity or function 304,
a response is returned to portable communication device 320 via
communication node 303 and wireless transmission channel 302.
[0053] As one skilled in the art will appreciate, the present
invention provides a combination of features and capabilities that
have broad consumer applications. In one such application, the
device could be used for remote entry and query to electronic
commerce on the Internet. If a user is at a store shopping for a
specific product, and wishes to be assured of obtaining the most
favorable price, the user can employ the communication device of
the present invention to scan the product identification bar code
on the product, speed-dial to a specific Internet web site,
automatically up-load the scanned product number which would then
initiate an Internet-wide search for the same item. On completion
of the search, all prices compiled for that item (or selected
prices, e.g., the best five prices), and the Internet addresses of
where the prices were obtained, could be downloaded back to the
device. Additionally, the name and address of alternative stores
within an n-mile radius of the user's present location could be
downloaded. Location identification is accomplished by use of
either a Global Positioning System capability integrated into the
communication device or by determining the location of the cellular
communications tower first employed in the transmission of the
signal.
[0054] Should the user at that moment opt to purchase the product
via an Internet web site, the selected price/web site is
highlighted, the user places a finger on the biometrics pad (or
otherwise provides a biometric attribute) or keys a Personal
Identification Code, and depresses a pre-programmed "Purchase" key.
This action initiates a digital transmission to an Internet web
site where user identification is authenticated, credit card or
debit card information is again validated, and the order is placed.
Alternately, the compiled price list could be used by the user to
negotiate with the store where the product code was scanned to
obtain a better price at that store.
[0055] Preferably, the digital transmissions, and particularly
transmissions concerning purchases, are encrypted for transmission
and decrypted upon receipt, using an accepted, conventional
encryption/decryption technology. For example, public key--private
key encryption such as RSA or Elliptical encoding/decoding.
[0056] In another application, the portable two-way communication
device can be used as a personal cash register. In this
circumstance, as the user selects items from a merchant's shelves,
the product identification bar code on each selected item is
scanned. Once shopping is complete, the user proceeds to the
merchant's cash register at which time the user will enter a
biometric attribute, for example, scan a fingerprint or retina or
reenter and verify a voice print, or key their Personal
Identification Code (PIN) into the device (or some combination of
these), and then press a pre-programmed "Purchase" key. This action
will initiate a secure communication means, such as an encrypted
wireless telephone call, infra-red wireless line of sight
connection, a radio frequency wireless connection, or a wired
electronic bus connection, as appropriate, to the merchant's cash
register, bank or financial clearinghouse. The accumulated product
identification numbers will be transferred to the merchant's cash
register or other designated site, along with the user's credit
card or debit card information that is stored in the secure memory
module. The merchant's cash register will determine the unit price
for each item, debit its inventory, credit its sales, and transmit
back to the user's communication device the total value of the
purchase charged to the user along with a transaction
identification code.
[0057] Alternatively, all items to be purchased could be scanned
and tallied by the merchant whereupon an invoice or cash register
receipt is presented to the user. The user could then scan the
receipt employing the imaging and OCR capability of the
communication device, or input a data (electronic or optical, wired
or wireless) feed from the merchant's system, automatically
interpret the amount being charged along with the merchant's
communication link instructions, input a biometrics attribute or
PIN, and press a pre-programmed "Purchase" key. This action will
initiate a secure communication means, such as an encrypted
wireless telephone call to the merchant's designated site and
complete the purchase transaction. In this manner, the user's
credit or charge authorizing means is never out of their possession
or control and unauthorized seizure or duplication of the user's
account information is impossible.
[0058] In yet another application, the portable two-way
communications device could be used as a wireless imaging device
for capturing and transmitting digital images. While a user is on
Vacation/Holiday, or at a trade show, or the like, the imaging
module integrated into the communications device can be fitted with
a lens modifying diopter which would provide a wider field of view
and/or greater depth of field, appropriate for the moment. By
selecting a pre-programmed "Photo" or "Full Video" function on the
communications device, single or sequentially scanned images can be
captured and automatically up-loaded to a remote site or e-mail
address for mass storage. This not only eliminates the need for a
large on-board memory capacity within the communications device,
which is preferably a miniature device, but also provides for the
immediate sharing of captured images with others. Remotely stored
images may then be downloaded for viewing on the user's or any
authorized or permitted individual's portable two-way
communications device, personal computer, or a television set (via
a web-capable cable box). This feature accommodates both casual
recreational use and the need for instant communication and image
transmission from the scene of fast-breaking new events and/or
matters of interest to business people.
[0059] In still another application, the portable two-way
communications device could be used as a wireless tool for
transmitting and receiving continuous digital images during video
teleconferences. The device could be used independently, more
preferably in conjunction with a base/charger unit. Such a
base/charger unit, could, for example, include a wide-angle,
multi-directional digital camera, a video monitor/PC port, and a
line power supply, and be linked to broadband communications, when
necessary. In this manner, the capabilities of a miniature
communications device can be further augmented and it can be used
for extended periods of time without concern for battery life.
[0060] In a further application, the portable two-way
communications device could be used to compile a grocery list and
subsequently order groceries for delivery. This would be
implemented by selecting a pre-programmed "Grocery List" function
on the communications device application menu. Thus, upon the final
use of each grocery product, the product identification bar code
printed on the product container or wrapper can be scanned for
repurchase. When it is time to replenish pantry supplies, the
"Grocery List" option is selected and a speed-dial number to an
Internet web site can be "pressed." Once connected to the site, the
accumulated product identification bar code numbers are
automatically up-loaded. Several further options then become
available. The user may next select a "Purchase" option, whereupon
the user enter a biometrics attribute, or PIN into the device. This
action will cause the shopping list to be forwarded to a local
supermarket web site or the like, along with the user's authorizing
credit card or debit card information, for list fulfillment and
delivery or pick-up as may be arranged. The user may alternatively
select a "Print" option whereupon the accumulated product numbers
are compared to a product number database located at an Internet
web site causing the adjective description of each product to be
extracted and compiled in a text narrative list. The list is then
forwarded to the user's e-mail address for download and print or
directly back to the portable communication device which
retransmits the list to a local printer via wireless, typically
infrared, transmission. Alternatively, the list could be sent by
fax to the user or to a store for list fulfillment. Of course, a
docking station could be used which provides wired or infrared
wireless access to a printer. Should the user also be taking
advantage of web-based menu services which provide ingredient
lists, the two lists could be compared and augmented prior to
download and print or forwarding to a supermarket web site for
fulfillment.
[0061] In yet another application, the miniature portable two-way
communication device could be used to ensure the accurate
ordering/reordering and purchase of drugs and medications. Once the
user's valid prescription is on file at a drug store or on-line
pharmacy, the user could employ the communication device to scan
the medication's NDC number or other unique identifying indicia.
Employing either OCR or, preferably, scanning a two dimensional
matrix or bar code such as Data Matrix or PDF 417 or the like, the
communication device could automatically interpret the NDC number,
usage instructions, number of authorized refills, prescription
number, and patient name. Subsequent to scanning a biometric
attribute, or keying a PIN, this information could then be
transmitted to the selected pharmacy, along with the user's credit
card or debit card information, whereupon the order would be
filled.
[0062] In another application of the invention, if a user were to
witness a crime in progress, the portable two-way communication
device could be pointed toward the crime scene, activate the
digital imager in a video mode, and dial 911. The real-time image
of the events being viewed could be conveyed contemporaneously to
the police along with the precise coordinates of the present
position. In this manner, the police would have an accurate
assessment of the situation on the scene and the precise location
of the crime. Assistance could be dispatched instantly and
appropriately without a spoken word necessarily being
exchanged.
[0063] In still another application, should the portable two-way
communication device ever be stolen, the device could be remotely
disabled in part or full, and its present location precisely
determined. Further upon first activation of the unit by the thief,
a voice print could be captured and a signal could be sent by the
receiving station back to the miniature portable two-way
communication device disabling all functionality, erasing the
personal database, and forcing the device to remain in the "on"
position. In this manner, the continuous signal emitted by the
device to a network operator or internet node would enable law
enforcement to track the location or movement of the device
facilitating its recovery and apprehension of the thief.
[0064] In a further application, the portable two-way
communications device could be used to acquire and display roadmap
and travel assistance instructions. An interactive connection could
be made to one of many Internet web-sites providing maps and
driving instructions. The maps and driving instructions could be
downloaded and displayed on the device screen, or alternatively on
the larger display screen that would be provided with a car kit. At
the same time, points of interest can be highlighted, restaurants
and hotels located, or reservations made.
[0065] In another application, the portable two-way communications
device could be used by delivery drivers and postal personnel for
not only two-way voice communication and route directions, but also
for parcel delivery verification, signature capture, and real-time
update of central databases containing parcel track and trace
information.
[0066] In another application, the portable two-way communications
device could be used to transmit text and graphical data acquired
by separate, special-purpose, equipment such as portable
electrocardiogram machines, other medical devices, such as scales,
EEG, glucose monitors, spirometers, or other electro-optical
devices. Interface compatibility enables the portable two-way
communications device to receive infrared, radio frequency, or
other short-range signals from special purpose equipment for
conversion and retransmission of the signal via radio frequency to
networks and locations throughout the world.
[0067] One skilled in the art will appreciate that the present
invention can be practiced by other than the embodiments disclosed
herein, which embodiments are presented for purposes of
illustration and not of limitation. Further, it should be
understood that the specific examples and
