Title: Switching of microphone in noisy environment by speech signals - with speech detection by circuit sensitive to short period sound variations
IPC: H04M9/10
Filed: 1978-10-23
Abstract: A microphone (11) situated in a noisy environment, is extended by a line (12) to a switch (14) and is connected to a network (13, e.g., the intercom system of a tank, when speech signals are detected by a detector (16) connected in parallel to the line (12).

Title: Electronic opener for fire exit or emergency door - uses battery, electronic voltage multiplier and solenoid, triggered by emergency sensor
IPC: E05B47/02
Filed: 1982-08-09
Abstract: Emergency exits are usually opened using a key. Disadvantages of keys are that: - the key may not be immediately accessible; - using a key takes time which may be critical; and the key may be available for unauthorised use of the door. The present opener operates immediately it is triggered, does not depend on external power sources and can be triggered by any electronic, electrical, mechanical or optical sensor. The door opens when the energy stored in a capacitor is transferred to a solenoid coil. The capacitor is charged to between 100 and 150 volts by an electronic voltage multiplier, powered by an internal battery. The battery, e.g. a lithium, nickel cadmium, alkaline or mercury type, delivers between 3.5 and 4.5 volts. If the circuit, which draws a rest current of only 100 nano-amperes, is tested once a month, the battery should last at least 5 years between replacements.

Title: Software routine for distributed data processing network - transfers routine functions from machine to machine via bus network
IPC: G06F9/46
Filed: 1988-08-12
Abstract: The program controls 'migrating' message transmission processes in an object-oriented network which has multiple computer stations. Each station operates the program according to an eight-step routine. Each byte transmitted via the network bus is detected (1). If it is not a 'send message' byte (2N) the routine examines (3) the next byte. If it is a send message byte '2Y) it is examined (4) to see if it refers to another station; if not (4N), it is interpreted (6). If the interpretation is unknown (6N), the local station (7) returns a 'send message' signal. If the message is recognised (6Y) the address is checked (8) and the message is steered to the local (7) or remote station (5) addressed.
