Abstract

A remote control device is adapted to control a plurality of appliances such as televisions, VCRs, stereos, etc. The remote controller includes a first connector for mating with a plurality of transducer modules, so that the remote control device can be used to emit infrared, radio, or other signals. (In another embodiment, the remote control device includes a plurality of different transducers for providing a plurality of different types of control signals.) The remote control device includes a second connector for mating with a cradle. The cradle can receive signals from external source such as a telephone line. Thus, one can access the remote control device from a remote location and cause the remote control device to control selected appliances. The remote control device also includes a programmable timer so that various appliances can be turned on and off at selected times.

Claims

1. A remote control device comprising:

at least one manually actuatable control element;

transducer means for emitting a signal;

circuit means for causing said transducer means to emit said signal in response to said control element being actuated;

serial input means for receiving a command signal from an external source and communicating said command signal to said circuit means, said command signal causing said circuit means to cause said transducer means to emit a signal; and

output means for enabling said remote control device to provide signals to said external source to enable the remote control device to provide status information or other data from the remote control device to the external source in response to a request from said external source;

wherein said circuit means comprises memory means for storing a plurality of commands for causing said transducer means to emit different signals, said serial input means permitting data to be loaded into said memory means from said external source.

2. The remote control device of claim 1 wherein said serial input means is coupled to a computer.

3. Remote control device of claim 1, wherein buffer means is coupled between said serial input means and said external source so that data can be provided to said buffer means at a first rate that is different from the rate at which said buffer means provides data to said serial input means.

4. Remote control device of claim 1 wherein said serial input means receives data at a rate of 19.2 Kbaud.

5. A remote control system comprising:

at least one manually actuatable control element;

transducer means for emitting a signal;

circuit means for causing said transducer means to emit said signal in response to said control element being actuated; and

a modem for receiving a command signal from an external source and communicating said command signal to said circuit means, said command signal causing said circuit means to cause said transducer means to emit a signal, said modem providing status information or other data from the remote control system to the external source in response to a request from said external source, where said circuit means comprises a memory means for storing a plurality of commands for causing said transducer means to emit different signals, said modem permitting data to be loaded into said memory means from said external source.
