摘要： A compact transformer coupled modulator is described. The modulator includes a transformer comprising a primary and a plurality of secondary windings, where each secondary winding has an output terminal. The modulator also includes a plurality of switches, where each switch is associated with a respective secondary winding and has input and output terminals and a control terminal. The control terminal of each switch is in electrical communication with a respective output terminal of the plurality of secondary windings. Each of the plurality of switches is substantially simultaneously switched by an input signal applied to the primary.

摘要： An electronic system is provided for use with motor vehicles, homes, offices, factories, or other applications where it is desired to control access and/or operation. The security system utilizes a coded electronic key, preferably in the form of a card, which is connected to a decoder for identification by composing the key code with a stored code. If the electronic key is properly matched to the decoder, the system is allowed to function without tripping alarms. The system includes monitoring devices, supervising cabling and various access points, such as doors, hoods, etc., which, if breached without the proper card in place, will trip an alarm. The system is deactivated with the proper key and the system includes appropriate delays to allow proper parties to move in and out of the secured vehicle, room, etc.
