`The remote control system includes a remote control
`and a computer having a memory and at least one of
`instruction codes or code data for creating appropriate
`IR lamp driver instructions for causing 'an infrared sig-
`nal generator to emit infrared signals which will cause
`specific functions to occur in a specific controlled de-
`vice, for operating a variety of devices to be controlled,
`stored in the memory'.of the computer. The remote
`control comprises: input circuitry including a set of
`keys or pushbuttons for inputting commands into the
`remote control, infrared signal output circuitry includ-
`ing IR lamp driver circuitry for supplying an infrared
`signal to a controlled devidei a central processing unit
`(CPU) coupled to the input circuitry and to the signal
`output circuitry, a memory coupled to the CPU, and
`data coupling circuitry and structure for periodically
`coupling the computer to the remote control for input-
`ting from the computer memory at least one of instruc-
`tion codes or appropriate IR lamp driver instructions
`for causing the infrared signal output circuitry to emit
`infrared signals wich will cause specific functions to
`occur in a specific controlled device, for operating a
`variety of devices to be controlled into the memory of
`the remote control to enable the remote control to con-
`trol various devices to be controlled upon the inputting
`of commands to the keys of the input circuitry.

`
`.FIELD OF THE ENVENTION
`The present invention relates to a universal remote
`control system including a remote control of the type
`which is hand held and which can be coupled via coded
`infrared signals with a remote control receiver built into
`a television or other remotely controlled electrical ap-
`paratus to turn on the apparatus, such as the television,
`at a distance, to adjust the volume, tone and brightness,
`to change channeLs, and to turn the television off and a
`data transmission system for inputting data to the re-
`mote control.
`2. Description of the Related Art Including Informa-
`tion Disclosed under 37 CFR Sections 1.97-1.99
`Heretofore it has been proposed to provide a recon-
`figurable remote control device and programmable
`functions for such a remote control device which will
`enable one to learn, store and retransmit infrared codes
`that are emitted from the controller for a remotely
`controlled apparatus, such as a television.
`For example, in the Welles II U.S. Pat. No. 4,623,887
`and the Ehlers U.S. Pat. No. 4,626,848, there is dis-
`closed a reconfigurable remote control device which
`has the ability to learn, store and repeat remote control
`codes from any other infr-ared transmitter. Such a
`reconfigurable, remote control transmitter device in-
`cludes an infr-ared receiver, a microprocessor, a non-
`volatile random access memory, a scratch pad random
`access memory, and an infraed transmitter.
`According to the teachings of the Ehlers patent, the
`infrared signals received by the remote control device
`are in bursts of pulses and the device counts the number
`of pulses in each burst as well as the time duration of
`each pause in a trnmiso between bursts.
`The Evans et al. U.S. Pat. No. 4,825,200 which issued
`on Apr. 25, 1989 on application Ser. No. 66,833, fied on
`Jun. 25, 1987, teaches a reconfigurable remote control
`transmitter that includes a learn mode and a run mode
`and is siilar to the remote control system disclosed in
`the Ehlers patent.
`Evans et al does not teach or suggest the provision in
`a universal remote control of data coupling means in-
`cluding terminal means (such as serial ports) coupled to
`a CPU for enabling code data to be supplied from out-
`side the remote control through the terminal means and
`CPU to a memory of the remote control
`The Imoto U.S. Pat. No. 4,71,283 teaches a system
`for the collecting of operating codes from various re-
`mote control transmitters by inputting the code data
`therefrom via infrared code signals to an infrared re-
`ceiving diode at an input of the system, deciphering
`those code signals, storing them in a RAM and then
`upon operation of keys, supplying outputs via one of
`several cables extending from outputs of the system to
`devices to be controlled.
`
`Imoto does not teach means for outputting infrared
`code signals nor does Imoto teach in a remote control,
`terminal means coupled to a CPU for supplying code
`* data from outside the remote control through the termi-
`v5 nal means and the CPU to a memory of the remote
`* control.
`

`trol at least one of (a) the instruction codes or (b) the
`30 code data for creating appropriate IR lamp driver in-
`structions, the code date causing the infrared signal
`output circuitry to emit infrared signals which will

`35 code data operating a variety of devices to be con-
`trolled and enabling the remote control to control vari-
`ous devices to be controlled upon the inputting of com-
`mands to the keys of the input circuitry.
`Further according to the invention there is provided
`40 a remote control system with data coupling including: a
`remote control, a computer having a memory, at least
`one of instruction codes or code data for creating ap-
`propriate infrared (IR) lamp driver instructions for
`causing an infrared signal generator to emit infrared
`45 signals which will cause specific functions to occur in a
`specific controlled device, for operating a variety of
`devices to be controlled, stored in the memory of the
`computer, a remote control comprising input circuitry
`including a set of keys or pushbuttons for inputting
`50 commands into the remote control, infrared signal out-
`put circuitry including IR lamp driver circuitry for
`supplying an infrared signal to a controlled device, a
`central processing unit (CPUT) coupled to the input
`circuitry and to the signal output circuitry, a memory
`55 coupled to the CPU, and data coupling circuitry and
`structure for periodically coupling the computer to the
`remote control for receiving from the computer mem-
`ory and inputting into the memory of the remote con-
`trol at least one of (a)- the instruction codes or (b) code
`60 data for creating appropriate IR lamp driver instruc-
`tions for causing the infrared signal output circuitry to
`emit infrared signals which will cause specific functions
`to occur in a specific controlled device, for operating a
`variety of devices to be controlled into the memory of
`65 the remote control to enable the remote control to con-
`trol various devices to be controlled upon the inputting
`of commands to the keys of the input circuitry and a

`
`and a lower housing member 16. An overlay face panel
`18 is positioned over the base panel 14.
`The two panels 14 and 18 have openings 22 and 24
`(FIG. 2) therethrough for receiving elastomeric push.
`buttons 25, all of which extend from and are fixed to or
`intga Iwith an elastomeric body panel 26 as shown in
`FIG. 2.
`The pushbuttons 25 are arranged in rows and col-
`umns and are identified as follows on the overlay face
`panel 18:

`
`pushbuttons 25 to perform numerous other functions as
`called for.
`This mechanical construction of the upper and lower
`housing members 12 and 16 and the panels 14 and 18
`5and circuit board 36 enable the control device 10 to be
`modified to include additional circuits in the operating
`circuitry 42 and pushbutton switches 25 for performing
`additional functions, if desired. In this respect, overlay
`face panel 18 is easily replaceable to modify the device
`010 to include more or less pushbuttons 25 and associated
`switches 38.
`The simplicity of the construction of the pushbuttons
`25, the base panel 14 and the overlay panel 18 is shown
`in FIGS. 3-6. As shown in FIG. 3, the body panel 26
`1has a plurality of raised pushbuttons 25 formed thereon.
`Each raised rectangular button 25 has a recessed area or
`hollow 48 on the underside 49 of each button 25 in
`which is mounted a conductive plunger or puck 50
`3adapted to engage one of the conductive switches 38 on
`the circuit board 36. With the pushbuttons 25 and the
`panel 26 being formed from a sheet of elastomeric mate-
`rial it is an easy matter to remove the buttons 25 that are
`not necessary with a scissors or other cuttng element,
`This arrangement is shown in FIG. 15 and the man- 2
`5as shown in FIG. 4.

`Then, the pushbutton body panel 26 is moved into
`ing the control device 10 will be described in greater
`engagement with the base panel 14, as shown in FIG. 5,
`detail in connection with the description of FIGS.
`to form the assembly shown in FIG. 6.
