  • RDS audio receiver having interrupt mode
    Patent number: 5548828
    Abstract: A Radio Data Systems (RDS) receiver has a decoder circuit to read RDS data from a broadcast transmission signal. From the RDS data, a control circuit determines a program of the received signal, a program category of the received signal, lists of programs and program categories of other stations, and a regional digit. The receiver has a controller to store a desired program category. The RDS data is used to control the receiver to perform several different functions. The receiver will interrupt reception of a signal, the category of which is different from a desired category and receive a signal that matches the desired category. The receiver will revert to a previous program when the category of the signal to which it switched no longer matches the desired category. The receiver will revert to the strongest signal having one of a specified set of regional digits. The receiver also permits the storage of a desired category using only an RDS key and at least one other key.

  • Password controlled anti-theft system for discouraging theft of a multiple-apparatus system
    Patent number: 5111185
    Abstract: A password anti-theft system for a multiple-apparatuses system, in which a central apparatus has at least one peripheral apparatus connectable thereto. When the peripheral apparatus is connected to the central apparatus, entry of passwords respectively peculiar to the central apparatus and the at least one peripheral apparatus concurrently releases the burglary modes of the central and peripheral apparatuses. When the peripheral apparatus is disconnected from the central apparatus or independent of the password system, entering the peculiar password of the central apparatus only releases the burglary mode of the central apparatus.

  • Car electronic device having antitheft mechanism
    Patent number: 4838377
    Abstract: An antitheft mechanism for an electronic device to be used in a car has three modes of operation. A normal operation mode permits continuous operation of the device. A line mode permits normal operation for a limited time after which it is replaced by a theft mode. The theft mode inhibits normal operation of the device until a secret code is entered into the device to return it to the normal mode or until a specified common operation of the device returns it to the line mode.
