摘要： Methods and apparatus for the recording and playback of animation control signals, including voice, are disclosed. In accordance with the method, a dual track cassette recording is made, one track consisting of a voice channel and the other track consisting of a plurality of control signals for the control of animation, and in some instances for control of the speaker or speakers through which the voice channel will be played back, whereby two or more animated characters may appear to speak to each other or speak or sing in unison are disclosed. The control signals are pulse width modulated signals to provide, in general, proportional control signals to provide proportional control, through appropriate servo motors and the like, of the animated elements such as mouth, eyes, etc. of the animated character. The pulse width modulated signals, together with a sync signal, are recorded directly on a cassette tape without modulation on a carrier frequency, despite the varying unsymmetrical wave forms, thereby allowing the compaction of a substantial number of control signals within the frequency band of reasonably priced playback units.

摘要： A remote keyless entry system particularly suited for preventing access to unauthorized individuals by securely encrypting messages transmitted from a remote transmitter to a receiver. A unique encryption algorithm is used to generate a multibit message having a pseudorandom number, key code and transmitter identification code (ID) encrypted within. The encryption algorithm generates said multibit message as a function of a pseudorandom number generator, a fixed key code table, ID and a switch, e.g., command, code. A receiver can decrypt the message to obtain the switch code and will respond thereto only if the message originated from an authorized transmitter, i.e., if the received pseudorandom number, key code and ID match those stored within the receiver.
