Abstract
Abstract A remote control set is provided for two like or similar devices, each of which is adjustable by remote control independently of the other, for example beds in a room. Normally, each operator controls the functions of his/her device by means of his/her remote control transmitter, and only if necessary will he/she control the functions of the device of the partner. Erroneous operation of the partner's device is thus prevented to the greatest possible extent. For this purpose, a pushbutton switch is provided in each of the two remote control transmitters. When and as long as the pushbutton switch of the one transmitter is actuated, it controls the functions of the receiver of the partner.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
243 words
A remote control set for controlling two devices by remote control independently, comprising: first receiver for receiving signals directed to controlling a first device; second receiver for receiving signals directed to controlling a second device; a first remote control transmitter; a second remote control transmitter; said first remote control transmitter and said second remote control transmitter each comprising a device selector switch, wherein: said first remote control transmitter communicates with said first receiver when the device selector switch of said first remote control transmitter is in a first position; said second remote control transmitter communicates with said second receiver when the device selector switch of said second remote control transmitter is in said first position; said first remote control transmitter communicates with said second device when said device selector switch of said first remote control transmitter is in a second position; said second remote control transmitter communicates with said first device when said device selector switch of said second remote control transmitter is in said second position; said device selector switches being in said second position only while being manually depressed, so that as long as said selector switch of said first remote control transmitter is manually depressed, operation of said second receiver is controlled by said first remote control transmitter, and so that as long as said device selector switch of said second remote control transmitter is manually depressed, operation of said first receiver is controlled by said second remote control transmitter.
Claim 2
Dependent Claim
243 words
A remote control set for controlling two devices by remote control independently, comprising: first receiver for receiving signals directed to controlling a first device; second receiver for receiving signals directed to controlling a second device; a first remote control transmitter; a second remote control transmitter; said first remote control transmitter and said second remote control transmitter each comprising a device selector switch, wherein: said first remote control transmitter communicates with said first receiver when the device selector switch of said first remote control transmitter is in a first position; said second remote control transmitter communicates with said second receiver when the device selector switch of said second remote control transmitter is in said first position; said first remote control transmitter communicates with said second device when said device selector switch of said first remote control transmitter is in a second position; said second remote control transmitter communicates with said first device when said device selector switch of said second remote control transmitter is in said second position; said device selector switches being in said second position only while being manually depressed, so that as long as said selector switch of said first remote control transmitter is manually depressed, operation of said second receiver is controlled by said first remote control transmitter, and so that as long as said device selector switch of said second remote control transmitter is manually depressed, operation of said first receiver is controlled by said second remote control transmitter.
Claim 3
Dependent Claim
157 words
A remote control set according to claim 1, wherein each remote control transmitter comprises an integrated circuit having an address gate terminal and address selection terminals of higher and lower order addresses, with the higher-order address selection terminal having priority when two address selection terminals are selected, wherein: the address gate terminal is connected to the lower-order address selection terminal and, via an emitter-to-collector path of a switching transistor, to the higher-order address selection terminal; parallel to the emitter-to-collector path of the switching transistor, a voltage divider is arranged which consists of the device selector switch and a resistor and the tap of which is connected to the base the switching transistor; and in the first remote control transmitter, the device selector switch is positioned between the base and the collector of the switching transistor, and in the second remote control transmitter, the pushbutton switch is positioned between the emitter and the base of the switching transistor.
Claim 4
Dependent Claim
18 words
A remote control set according to claim 2, wherein the voltage divider comprises a terminal of reversible polarity.
