Abstract: A microprocessor control system is described for effecting channel tuning and function selection in a television receiver. The system will respond to commands entered by a set of controls at the television receiver or to remote control commands received at the television receiver. A channel number display is also provided whereby the channel number of a station currently tuned is displayed. A microprocessor within the system is programmed to validate control information received from an operator either by remotely generated commands or by controls located on the television receiver. Operator supplied information is processed and implemented by the microprocessor control system to effect control over the television receiver.

Abstract: This invention relates to the remote wireless control of electrical AC and/or DC appliances, devices, apparatus without relay attachments to the appliance or to the motor driving the appliance or device or modification to the appliance or device. The level of operation of devices may further be controlled remotely, wirelessly, via amplitude modulation, phase, or pulse, or by increasing or decreasing frequency. Motor speed may further be controlled by a beam of visible or invisible light, or by preprogrammed signal eminating from a tape recording or other programmed material. The operation of one or more devices may be also varied automatically remotely, wirelessly, in or out of sequential order.

Abstract: A remote control system for TV receiver control. The system uses infra-red transmission to trasmit an infra-red data pulse on each edge of a pulse duration signal comprising a coded pattern of binary 0 and 1 bits which are formed by pulses of respective different lengths. The original pulse duration signal can be reconstituted at a receiver by a bistable element which is responsive to the infra-red data pulses. Since the regenerated modulating waveform could be in anti-phase with the original modulating waveform, the sequence of data pulses is transmitted twice and an additional data pulse is transmitted between successive transmissions, so that one or the other of the two regenerated modulating waveforms must be in phase with the original modulating waveform.
