Abstract
A remote control device stores commands which are received through a telephone line and transmits command signals to operate designated apparatus according to the stored commands. These command signals may be transmitted by infrared light or supersonic waves through one or more transmitters.
Claims13
A remote control device comprising
- memory means for storing data transmitted through a telephone line for the operation of selected apparatus,
- control means for controlling said selected apparatus according to said data stored in said memory means, said control means including an infrared light transmitter and controlling said selected apparatus according to said data by transmitting control signals to said apparatus through said infrared light transmitter, and
- testing means for testing whether said infrared signal light transmitter is properly functioning for the purpose of remote control, said testing means including means for selecting one of a plurality of ports through which current passes to said infrared light transmitter.
A remote control device comprising
- memory means for storing data transmitted through a telephone line for the operation of selected apparatus,
- control means for controlling said selected apparatus according to said data stored in said memory means, said control means controlling said selected apparatus according to said data by transmitting control signals to said apparatus through cordless transmitting means, said control means including a signal transmitter assembly having a plurality of wave emitters affixed at different vertical angles with respect to a rotatably supported horizontal board.
A remote control device for controlling operating conditions of apparatus on the basis of data transmitted through a telephone line, said device comprising
- memory means for storing a preselected access code and control data,
- clock means for counting time,
- controlling means programmed to output a detection signal when the number of call signals sequentially received through a telephone line has reached a predetermined number of times, to thereafter accept an access code inputted in response to said detection signal, to output an agreement signal if said accepted access code matches a preselected access code stored in said memory means, to cause control data for selected apparatus to be received by said remote control device in response to said agreement signal, to store said received control data in said memory means, and to output a control signal for controlling operations of said selected apparatus according to said control data by comparing time data received from said clock means and said control data, and
- an infrared transmitter assembly connected to said controlling means to receive said control signal and to transmit infrared control signals for controlling operations of said selected apparatus, said infrared transmitter assembly including a plurality of wave emitters affixed at different vertical angles with respect to a rotatably supported horizontal board.
