`WIRELESS AND WIRED
`COMMUNICATIONS, COMMAND,
`CONTROL AND SENSING SYSTEM FOR
`SOUND AND/OR DATA TRANSMISSION AND
`RECEPTION
`
`FIELD OF THE INVENTION
`
`The present invention relates to a wireless and wired
`communications, command, control and sensing system
`comprising a handset and base station, for the two way
`communication of sound, voice, and data with any appliance
`and/or apparatus capable of transmitting and/or receiving
`compatible sound, voice and data signals.
`
`BACKGROUND OF THE INVENTION
`
`Currently, there are prior art devices for remotely con-
`trolling appliances using infra-red (IR) signals. Further.
`thereare prior art devices which offer communications using
`radio frequency (RF) signals. However, few devices effec-
`tively combine both technologies. For example, U.S. Pat.
`No. 5.138.649 discloses an apparatus that controls a televi-
`sion and conducts telephone functions through a cable
`television converter and a base unit that incorporates a
`telephone radio frequency transceiver and a modem that
`interfaces with the telephone line. This arrangement has
`disadvantages since current televisions and cordless tele-
`phone bases on the market do not have such converters and
`modems and are notlikely to be retro-fitted. Secondly, there
`are manytelevision owners that do not have television cable
`boxes.
`
`Further, the disclosed apparatus also provides a means for
`communicating with infra-red signals in one direction only.
`It does not provide for the use of infra-red communications
`as an alternate or full backup system to the radio frequency
`communications link. As a result, the command and control
`of an infra-red sensor equipped apparatus is severely limited.
`Further still. in medical or industrial uses, where RF radia-
`tion is detrimental, this disclosed apparatus is placed at a
`significant disadvantage.
`if not
`impossible to use.
`In
`addition, the disclosed alternative of using radio frequency
`(RF) for audio signals only and infra-red frequency for one
`way communication of telephone control and data signals
`severely limits the utility of the apparatus: (1) it does not
`provide an IR data path from the base to the handset for
`control as required for full telephone operations and (2) it
`will not work in environments where the need for full two
`way data and/or voice transmission in the IR domain would
`be necessary.
`Accordingly, it is an object of the present invention to
`provide full two way RF and IR communication links to all
`types of apparatus and/or appliances for home, business,
`medical or industrial use. Single RF or IR links or combi-
`nations of RF links and IR links for performing integrated
`functions would have significant advantages. The ability to
`communicate directly with an appliance or apparatus from a
`unified wireless and/or wired communications, command,
`control and sensing device, in either full two way RF or IR
`link modes and without having to use a converter with a
`modem or a stand alone base station as an interface, offers
`other major and significant advantages. Further. use of a
`base station independent of the handset
`to perform all
`communications, command, control and sensing functions
`offers convenient extended utility, reliability and availabil-
`ity. Also, optional use of the base station as a repeater
`extends the range at which the wireless communication link
`can be established and maintained. Use of the basestation as

`an option for coupling frequency modulated signals onto an
`AC power line offers other advantages. None of these
`advantages are met with prior art portable telephone hand-
`sets having IR remote controlsince their utility is driven by
`the interface with a television apparatus and access to a
`television cable line or through severely limited telephone
`base station functions. Further, prior art devices can not
`perform full telephone operations in view of a lack of an IR
`telephone control signal return link to the handset to perform
`handshake functions.
`It is another object of the present invention to provide a
`unified wireless and wired communications. command. con-
`trol and sensing system, in the form of a remote handset,
`base station, or both, each having a generalized signal
`generating and control structure that can interlace sound,
`including voice. command and control data and sensing
`data. The signais can be transmitted and/or received over a
`broad frequency range and linked to any number of appli-
`ances and/or apparatus capable of receiving and/or trans-
`mitting compatible signals without the requirement for a
`modem which adds unnecessary complexity and cost. Signal
`generation and control that is completely under micropro-
`cessor control, based on a generalized software architecture,
`overcomesthe limitations of the specific simple aggregation
`and utility of a remote control, television converter, and
`cordless telephone as embodied in the prior art.
`It is still a further object of the invention to provide fully
`integrated signal generation capability in a broad frequency
`range, from radio to infra-red frequencies, so that the fre-
`quency selection can be better matched to the operating
`environment of the communications, command, control and
`sensing device. Under some conditions the option to select
`frequency transmission or reception in either a radio fre-
`quency or infra-red frequency greatly enhances opportuni-
`ties to overcome environmental radiating problems. In some
`environments where radio frequency transmission may be
`detrimental to other operating devices, the option to transmit
`in the infra-red domain could be very beneficial. Similarly,
`where direct line of sight combined with reflecting surfaces
`still does not make infra-red transmission and reception
`practical, the use of a radio frequency capability is very
`beneficial. Being able to provide a backup signal link
`between radio frequency transmission or reception and
`infra-red transmission or reception could insure link con-
`nection should a particular componentfail in either the radio
`frequency or infra-red circuits.
`It is another object of the invention to provide a means for
`loading the microprocessor external memory of the handset
`or base station with updated or accessory programs and/or
`data bases. The loading can be accomplished via a telephone
`line, a telephone base unit transceiver, a personal computer,
`or an entertainment apparatus that operates in the RF and/or
`IR frequency domain and a communication link that can be
`established with the wireless communications, command,
`control and sensing device.
`It is still another object of the invention to use a micro-
`Processor and a generalized signal generation or control
`software to provide a flexible way to add accessory appli-
`ances or apparatuses without having to buy additional.
`non-compatible, hand-held remote control or other wireless
`communications devices. Many generations of products
`could be designed to take advantage of a knownor adaptive
`inter-device communications protocol.
`SUMMARYOF THE INVENTION
`
`In accordance with the present invention. a wireless and
`wired communications, command, control and sensing

`3
`system, in the form of a remote handset or basestation, or
`both, is provided. Both the handset and the base station have
`similar components and function in substantially the same
`manner. The base station may have additional features. for
`example: it couples a frequency modulated signal toalter-
`nating current (AC) powerline; it may be powered by an
`alternative alternating current (AC) signal and battery power
`sources; it may provide battery charging for the handset, and
`it may be coupled to public or private telephone lines. Both
`the handset and the base station contain a touch screen or
`similar touch sensitive device that when touched in at least
`one specific outlined area, provide the means for externally
`interacting with their respective microprocessors. This inter-
`action initiates the execution of a software instruction set.
`
`Both the handset and the base station have microproces-
`sors to controlall their internal operations. The handset and
`the base station microprocessors are configured to actuate
`internal circuits, make calculations, process data, generate
`and verify privacy codes for telephone communications,
`generate sound and/or data signals. control signal
`processing, control the reception and transmission of radio
`and/or infra-red frequency signals and activate access to
`public or private telephone networks. The microprocessors
`further provide programmingand selecting modes of opera-
`tion and functions. The microprocessors and associated
`software logically inter-relate data to generate information
`and general purpose commandand control signals that can
`be received and processed by different external appliances or
`apparatus. The microprocessors further generate signals that
`are coupledto a ringer of a telephone or other apparatus for
`paging. and performing other coded audio alert functions.
`Both the handset and the base station include a micro-
`phone. The microphones couple external sound signal.
`including voice signals, to a sound and data_coupler for
`subsequent
`transmission via radio and/or infra-red fre-
`quency transceivers. The microphonesfurther couple sound
`signals, including voice signals, to a voice recorder and
`player integrated circuit (IC) for storage and playback. The
`microphonesfurther couple external voice commandsignals
`to a voice activated device IC.
`
`Sound, voice, and/or data signals inputted via a micro-
`phoneare sent to a sound and data coupler for transmission,
`output to a speaker, and/or for processing by the micropro-
`cessor. Recording. playback and storing of sound signals,
`including voice signals, is provided, under microprocessor
`control, for message operations. The sound or voice signals
`are inputted via a microphone in some applications or
`inputted via transceivers in other applications. The signals
`are retrieved and played back, under microprocessorcontrol,
`via the speaker, and/or are coupled to the transceivers for
`transmission via radio or infra-red communication links.
`Voice command and/orcontrol signals which are input via
`the microphoneare detected by a voice activated device. The
`signals are converted into digital signals for input to the
`microprocessor. This voice command generated input is
`used by the microprocessor for internal operations. It may
`also be converted into command and control signals for
`transmission via a radio frequency and/or infra-red trans-
`ceiver to external appliances or apparatus.
`Radio and/or infra-red transceivers transmit and receive
`radio frequency and/or infra-red frequency signals. Typical
`radio transceiver functions include signal detection,
`modulation, demodulation, amplification, and noise reduc-
`tion through companding techniques. Carrier frequencies are
`provided by a frequency synthesizer which is controlled by
`the microprocessor. Digital to analog and analog to digital
`
`4
`signal conversion is provided for signal processing and
`communication in both analog and digital form. Radio
`transceivers in the handset and the base station couple
`sound, including voice signals, data and controlsignals. to
`and/or from a data detector. signal converters, a sound and
`data coupler, a speaker and respective microprocessor.
`Radio signals are coupled to and from open space via an
`antenna. The infra-red transceiver couples sound signals,
`including voice, data and control signals to and/or from the
`data detector. signal converters, a sound and data coupler, a
`speaker and the microprocessor.
`Infra-red signals are
`coupled to and from open space via infra-red light emitting
`and detection devices. These transceivers establish radio and
`infra-red signal communication links with external appli-
`ances and/or apparatuses, including handset to base station
`and base station to handset, having compatible receiver
`and/or transmission capabilities.
`Sensors embodied in the communications. command,
`control and sensing system detect physical phenomena dif-
`ferentials and convert these differentials into data signals.
`These data signals are coupled to microprocessors for fur-
`ther processing and outputto a liquid crystal display device.
`or similar device. a ringer and/or the transceivers. The
`communication. command, control and sensing system fur-
`ther includes means for transmitting the data signals to an
`external monitoring apparatus. Sensor data from external
`appliances and/or apparatus is received by radio and/or
`infra-red transceivers in the handset or base station and are
`coupled to a corresponding microprocessor. The respective
`microprocessor processes the external sensor data and out-
`puts it to the display device or re-transmitsit to an appliance,
`apparatus or monitoring device in the form of data,
`information, and/or command and control signals.
`The base station radio frequency transceiver further
`couples two way frequency modulated signals from and to
`alternating current (AC) powerline for two way communi-
`cation with other frequency modulation transceivers that are
`also coupled to alternating current (AC) power line.
`Thebase station further couples voice and data signals to
`public and/or private telephone network.
`Thebasestation is further powered by direct current (DC)
`signal and an alternating current (AC) signal power source.
`According to one aspect of the invention, command and
`control signals are initialized by touching a touch screen, or
`similar touch sensitive device. In response, the micropro-
`cessor generates data for actuating internal circuits and/or
`for causing changes in settings in external appliances and/or
`apparatuses. In another aspect of the invention, command
`and control signals are initialized by voice commands and
`are generated by a voice activation device. In response, the
`microprocessor generates data for actuating internal circuits
`and/or for causing changes in settings in external appliances
`and/or apparatuses. In both aspects, the communications.
`command, control and sensing system receives command
`and control signals that represent appliance and/or apparatus
`sensor status and/or measurement readings. The received
`data is processed by the respective microprocessor for
`display and/or automatic updates to command and control
`signals sent back to the external appliance and/or apparatus.
`External appliance and/or apparatus functions are con-
`trolled in response to a radio or infra-red command and
`control signal generated and transmitted by the wireless
`communications, command. control and sensing system.
`Passive external appliances or apparatuses, equipped with
`compatible receivers and decoding circuits, receive the
`commandand control signals. Signal processing electronics

`within the appliance or apparatus convert
`command and control signals into a switching or other form
`of operation. Active external appliances or apparatuses pro-
`vide setting condition or status signals which are detected by
`internal sensors of the system. These setting condition or
`status signals are converted by a microprocessor, or other
`electronic circuit, into signals for transmission to the wire-
`less communications, command, control and sensing system
`via a radio or infra-red communication link.
`All communication links between the communications,
`command, control and sensing system and external appli-
`ances and/or apparatuses are wireless, except where the base
`station is coupled to a telephone line and an alternating
`current (AC) signal powerline. These communication links
`are two way radio and/or infra-red links. For example, one
`external implementation comprises a door bell with inter-
`com. The corresponding appliance control signal comprises
`an actuation command to establish a wireless radio fre-
`quency communications link between the door intercom and
`the handset and/or base station. A second external imple-
`mentation comprises an audio alarm and a corresponding
`control signal, which is a radio and/or infra-red control
`signal link to activate a switch to power an alarm sound
`generator. A third external implementation comprises an
`alternating current remotely actuated switch, which receives
`a radio frequency coded command and powers up or
`changesthe voltage setting in a house light or other device.
`A fourth implementation used within the handset and/or base
`station comprises a voice recorder and playback IC device,
`under the control of a microprocessor, for automatic and
`multiple message transmission to the base station for con-
`nection to a telephone line. A fifth implementation used
`within the handset and/or base station, comprises the recep-
`tion of a message via the radio or infra-red transceiver and
`storage of the message for subsequent playback through the
`speaker, or re-transmission via the said transceivers. A sixth
`implementation used within the handset and/or base station,
`comprises receiving and processing remote sensor signals
`for displaying or processing by the microprocessor. A sev-
`enth external
`implementation comprises a generalized
`remote control data base driven signal generation for con-
`trolling entertainment appliances such as television, VCR,
`cable box and sound system. An eighth implementation
`comprises voice actuated command and control signal gen-
`eration for internal operations and/or for remote control of
`external appliances. A ninth implementation comprises a
`sensor embodied within either the handset or base station,
`which senses temperature, pressure or some other externally
`measurable human body condition which is then converted
`and processed by the respective microprocessorinto data for
`display or transmission along with a voice or other message.
`A tenth implementation comprises secure control signal
`generation and transmission to external appliances and/or
`apparatuses. An eleventh implementation comprises using
`the base station and/or handset microprocessor to perform
`programming functions, calculations and/or to execute spe-
`cific application programs. A twelfth implementation com-
`prises a wireless telephone operation between the handset
`and the base station which couples the signals to a private or
`public telephone network. A thirteenth implementation com-
`prises coupling frequency modulated signals to and from
`alternating current (AC) signal power line. A fourteenth
`implementation comprises generation and processing of a
`generalized voice, command and control signal protocol
`which is transceived between the handset and/or base station
`and/or an external device capable of receiving. processing
`and respondingto the signal.

`DETAILED DESCRIPTION OF THE
`INVENTION
`
`FIG.1a illustrates a wireless and wired communications,
`command. control and sensing system 1 including a handset
`device 10 and a base station 25 for two way communication
`of sound. voice, and data to perform telephone
`communications, remote command and control of appli-
`ances and/or apparatuses, remote monitoring. intercom and
`paging operations, and security functions utilizing both
`radio and infra-red frequencies.
`As illustrated in FIG. 15, external appliances and/or
`apparatuses may include an intercom 2. an alarm 3. an
`alternating current (AC) actuator 4,a TV 5. a VCR 6. a cable
`box 7, a sound system 8, a remote sensor 9, or any other
`RF/IR apparatus 11. As shown, handset 10 may communi-
`cate directly to any of the external apparatusesor directly to
`a base station 25. Alternately, base station 25 may commu-
`nicate directly with any of the external apparatuses or
`handset 10. Furtherstill. handset 10 may communicate to an
`external apparatus through base station 25. Finally. base
`station 25 may communicate through a telephoneline and/or
`an alternating current (AC) signal power line to any other
`apparatus having the ability to communicate through same.
`FIG. 2 illustrates a wireless communications, command,
`control and sensing handset device 10, in an enclosure 12,
`that when interconnected via a printed circuit board 90 and
`controlled by a handset microprocessor 30, performs two
`way wireless communication, command, control and sens-
`ing functions. In one embodiment of the invention, a Moto-
`rolla 6805 processor is used. However, as will become
`readily apparent to those skilled in the art, other micropro-
`cessors can be used. A touch sensitive device, such as 14,
`with pressure, inductive, reactive. light or other physical
`reactions respond to an external touch and produces an input
`signal to microprocessor 30, which in turn processes the
`signal and generates data, command and/or controlsignals.
`As will become readily apparent to those skilled in the art,
`touch sensitive device 14 may be a key pad, an optical
`device, a capacitive or inductive reactive device, or any

`other type of available control devices. The touch sensitive
`device may be overlayed with different overlay 13, which
`allows for designating a different set of functions that may
`be executed by microprocessor. The microprocessor instruc-
`tion set and data is stored in microprocessor 30 or in an
`external memory module 32, having preferably 16K byte
`memory capability. Selected data. command and/or control
`signals are displayed, in digital form, on a liquid crystal
`display 82 or similar display device. Two way sound and/or
`voice communication. including telephone communications,
`is controlled by microprocessor 30 via communicationlinks
`enabled by radio frequency transceiver 50 and/or infra-red
`frequency transceiver 60.
`Open architecture software within microprocessor 30
`creates a generalized command andcontrol protocol which
`makesit possible to interact. in a wireless mode, with any
`number of external devices that have compatible transceiv-
`ers with wireless communications, command. control and
`sensing handset 10. The software also provides all
`the
`internal controls and necessary protocols for specified radio
`and infra-red communication links. Control signals created
`by these protocols allow the system to be used as a wireless
`telephone or as a remote controller for entertainment appli-
`ances or alarm systems or energy control systems or for
`personal security operations, etc. Microprocessor 30 pro-
`vides all the timing via an internal or external clock. Data
`base updates and application programs can be down loaded
`into the microprocessor via the radio or infra-red commu-
`nication links. Data base updates can also be made via the
`touch screen or touch sensitive device. The operation of the
`microprocessor in conjunction with creating the control
`signals to remotely communicate with external appliances
`and/or apparatus is explained in detail hereinafter.
`One embodiment of handset 10, in accordance with the
`present invention, is configured to communicate with vari-
`ous devices such as TV sets, VCR sets, CD players, and
`Cable boxes. The handset is further configured to utilize
`several communication protocols employed by various
`manufacturers or various models of the same brand.
`Typically, each manufacturer of one of these devices such as
`TV sets, VCR sets, CD players and Cable boxes, employs a
`specific communication protocol that includes a command
`code set for performing various functions to remotely con-
`trol the device. Each command code set comprises a set of
`signals, wherein each signal is utilized to perform an avail-
`able function. For example, a TV set made by manufacturer
`A, may require a command code set that includes various
`signals to remotely control various available functions such
`as channel up, channel down, volume up, volume down,
`mute, and power “on” and “off”. This command code set
`may have a different set of signals than another command
`code set employed for a TV set made by manufacturer B.In
`the alternative. manufacturer A may employ different com-
`mand code sets for its own various models of TV sets.
`It will be appreciated that a handset that is capable of
`communicating with substantially all major brands ofvari-
`ous devices, or transmit infra red fr
