Abstract
Abstract Apparatus for remotely controlling the operation of various electronic devices comprises a remote-control unit having a read-only memory for storing a data table, a keyboard for generating a program to be executed at a predetermined future time, a random-access memory for storing the program, a central processing unit jointly interactive with the read-only memory and the random-access memory, and a transmitter controlled by the central processing unit for producing a remote-control signal based on the data table and the program. A receiver is responsive to the remote-control signal for controlling the devices in accordance therewith, and a simulator is provided for producing the remote-control signal before the predetermined future time, so that at least a portion of the program is pre-executed as a test of its validity.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
161 words
Apparatus for remotely controlling the operation of at least one electronic device; said apparatus comprising: a remote-control unit removeably attachable to a personal computer having a keyboard, said unit including a read-only memory for storing a data table, means for generating a program of events to be executed at predetermined future times, a random-access memory for storing said program, a central processing unit jointly interactive with said read-only memory and said random-access memory, and a transmitter controlled by said central processing unit for producing remote-control signals corresponding to said events and being based upon said data table and said program; a receiver responsive to said remote-control signals for controlling said device in accordance therewith; and simulation means for producing said remote-control signals and causing the respective events to occur before said predetermined future times in response to operations of said keyboard of the personal computer; whereby at least a portion of said program is pre-executed as a test of its validity.
Claim 2
Dependent Claim
161 words
Apparatus for remotely controlling the operation of at least one electronic device; said apparatus comprising: a remote-control unit removeably attachable to a personal computer having a keyboard, said unit including a read-only memory for storing a data table, means for generating a program of events to be executed at predetermined future times, a random-access memory for storing said program, a central processing unit jointly interactive with said read-only memory and said random-access memory, and a transmitter controlled by said central processing unit for producing remote-control signals corresponding to said events and being based upon said data table and said program; a receiver responsive to said remote-control signals for controlling said device in accordance therewith; and simulation means for producing said remote-control signals and causing the respective events to occur before said predetermined future times in response to operations of said keyboard of the personal computer; whereby at least a portion of said program is pre-executed as a test of its validity.
Claim 3
Dependent Claim
23 words
Apparatus according to claim 1; wherein said remote-control unit comprises a cartridge and said transmitter is an infrared transmitter attached to said cartridge.
Claim 4
Dependent Claim
25 words
Apparatus according to claim 1; wherein said program includes digital code signals that represent data, timer-ON time, and timer-OFF time, and specify said electronic device.
Claim 5
Dependent Claim
30 words
Apparatus according to claim 1; wherein said simulation means produces said remote-control signals in response to execution orders given by a user of the apparatus and entered through said keyboard.
Claim 6
Dependent Claim
20 words
Apparatus according to claim 1; wherein said transmitter comprises an infrared encoder and a light-emitting diode connected to said encoder.
Claim 7
Dependent Claim
59 words
Apparatus according to claim 1 for remotely controlling the operation of at least a tuner, a power amplifier and tape recording apparatus; wherein said receiver is connected to said tuner and adapted to enable said tuner to receive a broadcast signal in response to said program and to supply said broadcast signal to said tape recording apparatus for recording.
