  • Electronic calculator system having audio messages for operator interaction
    Patent number: 4060848
    Abstract: A calculator system is provided using a stored program data processor and an audio message subsystem to process digital information and to provide audio messages for operator interaction. The calculator system utilizes a digital data processor to execute program routines to process digital information and to communicate with an operator using audio messages. Digital message information is stored in a digital memory and is accessed in response to operator generated signals to provide audio messages.
    Type: Grant

  • Electronic lock and key system
    Patent number: 4036178
    Abstract: An electronic lock and key system is provided for controlling access. A passive key provides selective access without having a self contained power source. In a passive transponder arrangement, a passive electronic key processes induced or radiated electronic signals to generate a transponder signal for controlling access.

  • Apparatus and method for providing interactive audio communication
    Patent number: 4016540
    Abstract: A system for operator interaction is provided using a stored program digital data processor and an audio message sub-system to process digital information and to provide audio messages for operator interaction. The system utilizes a digital data processor to execute program routines to process digital information and to communicate with an operator using audio messages. Digital message information is stored in a digital memory. The digital message information is accessed in response to operator generated signals to provide audio messages, in contrast to the prior art visual messages using displays and printers.

  • Illumination control system
    Patent number: 3986022
    Abstract: Control of illumination with illumination amplifier devices provides a basis for implementing various types of illumination systems. Also illumination amplifiers in closed illumination servo loops provide improved illumination control. An illumination control system provides precise control of camera operations for photographic and photoplotter applications. Illumination amplifier devices are used in conjunction with electronic control circuits to provide flexibility and precision in camera systems, reducing reliance on prior art mechanical devices.Illumination control circuits are presented in the form of digital gates and flip-flops and in the form of analog computational elements to provide illumination computer systems. In addition, a batch fabricated illumination computer arrangement is presented for improved implementation of illumination control systems.Illumination amplifiers are further configured for control of illumination in buildings and automobiles.
