An identification system with a reading device having a single turn transmission coil for continuously radiating alternating energy. A portable tag receives via a magnetic coupling, the energy from the reader and charges a storage capacitor to 5 volts. The capacitor is discharged rapidly during a time period less than the charging time period. This discharge of the capacitor powers a coded information transmission circuit during a small percentage of the duty cycle.

Identification system and method with passive tag

A multiple channel cathode ray tube video display provides for adjusting brightness of the displayed channel by a single input control, such a trackball or keyboard, to a computer that generates a channel coded binary word that is held in one of a plurality of memory latches, each corresponding to a channel. The binary word is converted to an analog brightness signal that controls the gain of a corresponding one of a plurality of video signal amplifiers.

Programmable CRT brightness control

A solid state control panel system utilizing optical coupling between a graphic control panel and a hand-held probe is disclosed. Separate light emitting control diodes and display diodes are utilized on the graphic panel. In response to a coded optical coupling between selected light emitting diodes on the panel and a light sensitive diode in the probe, various switching functions are performed. The system provides three different types of coding for each complete switching operation, namely, time coding, polarity, and pulse sequence coding. The probe includes means to inform the operator when proper optical coupling occurs; and is so constructed mechanically that it can be operated by pressure engagement with the panel, or as a gun. The system is structured to provide various types of switching functions, including the provision for selecting any one of a plurality of individual switches in its present state for display and control with each selected switch having a multiplicity of states. Once selected, the system provides for sequencing the selected switch functions from its last operated state to its next sequential state. Provisions are included for automatically driving the individual switches or control groups to their last operated state automatically.
