Security control and alarm system

Abstract: A security control and alarm system includes a central station communicating with each of plural remote stations, or facilities, protected by the system. The remote stations may be multi-zone office buildings, shopping centers, or any of various specialized applications. The central station provides point-to-point monitoring of each protection sensor device at each remote station. Protection sensors of any desired type are encompassed by the system, including detectors for unauthorized entry, fire, smoke, mechanical equipment failure and the like. The central also provides remote control of various security functions including selective arming and disarming of the remote station, resetting of the alarm condition following an alarm activation, operating doors to permit access to authorized personnel, operating elevators to restricted, selected floors of a building, any of various other types of desired control functions. The system also may provide general remote control of non-security building functions. Communication between the central and remote is provided by an FSK-type multiplex mode of communication over standard voice grade telephone lines. Each person authorized to gain access to a remote, protected facility is provided a password. At the entrance of the facility, there is provided a telephone with a direct line connection to the central. An individual wishing to gain access must call and give the correct password to an operator at the central in response to which the operator issues a control to the remote facility for unlocking the entrance door. Elevator control is performed on the same basis. Parity check and general system test, in addition to various system operation monitoring and tamper detection means assure reliable operation of the system.

Remote control system

Abstract: A remote control system for use in remote controlling a television receiver is provided in which a light signal is used as the remote control signal. An electroluminescent diode is used to emit the remote control light signal which is amplitude-modulated by a modulating frequency in the ultrasonic frequency range and has a very narrow band of wave lengths. The remote control system is very compact in size and completely free from the erratic operations caused by the noise.

Safety control for a remote control system

Abstract: Safety control apparatus including a remote system for turning a zone heating and cooling air conditioning unit on and off from a central control point and a safety freeze control system for simultaneously switching the unit from a normal operating mode to a heating mode at a predetermined temperature and overriding the remote control system

Remote searchlight control system

Abstract: A remote control system for controlling the azimuth and altitude of a searchlight and also a control for selecting one of two modes of operation, either spot or flood, of the searchlight. The system includes a dual remote control of the spotlight, for use in vehicles, such as boats, where it is desired to control the direction of the spotlight and mode of operation from two separate locations. The system includes means for locking out one remote control position when the other remote control system is actuated.

How Computer Aided TV Remote Transmitter Desisn was Accomplished

Abstract: In this computer era, most engineers have benefitted tremendously from use of computers. This paper explains the application of computer-aided design to the remote control transmitter for the Magnavox deluxe color T. V. remote control system.

Man-Machine Interactive Imaging and Data Processing Using High-Speed Digital Mass Storage

Abstract: The role of vision in teleoperation has been recognized as an important element in the man-machine control loop In most applications of remote manipulation, direct vision cannot be used To overcome this handicap, the human operator's control capabilities are augmented by a television system This medium provides a practical and useful link between workspace and the control station from which the operator perform his tasks Human performance deteriorates when the images are degraded as a result of instrumental and transmission limitations Image enhancement is used to bring out selected qualities in a picture to increase the perception of the observer A general purpose digital computer, an extensive special purpose software system is used to perform an almost unlimited repertoire of processing operations
