Title: Transportable programmed transmitter connectors for a security system
Inventor: BURGMANN THOMAS A D
IPC: G08B25/10
Filed: 1987-11-09
Granted: 1991-03-05
Abstract: ABSTRACT OF THE DISCLOSURE         A security system for sensing the status of various security detectors used in, for example, home security such as fire, intrusion, emergency and appliance operation protection is disclosed.  The detectors transmit, usually via radio frequency, various massages to a central monitor.  To enable proper communication, the transmitters are programmed to transmit messages unique to the originating detector. The transmitters may be programmed at one station and then moved to the detector for insertion therein. During this transport, it is important that a volatile memory of the transmitter be retained.  This is accomplished by a low power source.  A disarming device is provided to disarm the transmitter during transport to prevent the transmitter from draining a short term power source by transmitting a message.  This avoids the loss of any programmed information in the evaporative memory.

Abstract: ABSTRACT "Detonator Firing System"     A system is provided for initiating a blasting cap wherein pulsating light energy is converted to electrical energy.  An optical coupler couples the source of energy to a remote firing arrangement to transfer the generated pulsating light energy to the firing arrangement.  An electrical connection connects the firing arrangement to an ignition resistor in a detonator.  Thus, the generated light energy is converted to electrical energy and is transferred to the ignition resistor, the transferred electrical energy being the firing energy for the ignition resistor.

Granted: 1992-02-04
Abstract: ABSTRACT        A method and apparatus for generating addresses for a distanced vector address or a constant stride vector address.  The address generator generates the requested address indices following an equation c.D = 1(mod B) where B is the bank number of the memory device, D is the distance of the vector address and c is a positive integer called as delta index.  By doing so, the requested addresses are successively generated in order of bank addresses of a memory device which stores the vector address.  So, the waiting time which has been necessary for skipping the banks form one address to next address in prior art distanced vector access method has been eliminated.  And the throughput of the memory device is improved to a greater extent.
