`ABSTRACT
`[57)
`
`An interactive microprocessor based wireless communica(cid:173)
`tion device includes sound and data transceivers. signal
`detection and coupling devices, signal conversion device.
`voice recording, playback and storage device. voice acti(cid:173)
`vated device. display device. touch screen or similar device.
`sensors. frequency generation device. sound detection and
`reproduction devices and power source to concurrently
`perform generalized two way wireless communications.
`command. control and sensing functions utilizing radio and
`infra-red frequency communication links. A microprocessor
`receives signals from the touch screen and generates a
`digital data. command/or control signal for transmission to
`external devices such as home appliances and remote sen(cid:173)
`sors. The microprocessor also responds to voice signal
`commands received via microphone and a voice processor.
`The microprocessor uses this signal to generate data.
`command/or control signals for transmission to external
`devices such as telephone. paging and intercom systems.
`Sound signals may be stored in a voice recorder and play(cid:173)
`back IC for subsequent message processing and coupling to
`a transceiver and/or a speaker. Telephone ringer signals are
`generated by the microprocessor and are coupled to a ringer
`for audio output. In response to certain commands. the
`wireless communication device establishes a communica(cid:173)
`tion link with external devices using radio frequency or
`infra-red frequency transmission and/or reception. Sensor
`signals are created by sensors that can detect physical
`differential changes and that can convert the changes into
`measurements. These signals are coupled to the micropro(cid:173)
`cessor for further processing, display and/or transmission.

`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(cid:173)
`trolling appliances using infra-red (IR) signals. Further,
`there are prior art devices which offer communications using
`radio frequency (RF) signals. However, few devices effec- 20
`tively combine both technologies. For example, U.S. Pat.
`No. 5.138.649 discloses an apparatus that controls a televi(cid:173)
`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 25
`interfaces with the telephone line. This arrangement has
`disadvantages since current televisions and cordless tele(cid:173)
`phone bases on the market do not have such converters and
`modems and are not likely to be retro-fitted. Secondly, there
`are many television owners that do not have television cable 30
`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 35
`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(cid:173)
`tion is detrimental, this disclosed apparatus is placed at a
`significant disadvantage. if not impossible to use. In 40
`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 45
`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 50
`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(cid:173)
`nations of RF links and IR links for performing integrated
`functions would have significant advantages. The ability to 55
`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 60
`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 65
`extends the range at which the wireless communication link
`can be established and maintained. Use of the base station as
`
`2
`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(cid:173)
`sets having IR remote control since their utility is driven by
`5 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
