A multi-function customer satisfaction survey device, system and method. A plurality of stackable tip trays in a restaurant each include a survey device and a calculator. Survey questions are presented on a display screen, and a survey keypad is used by the customer to enter responses. The responses are stored in a memory in the tray. The trays stack on a base unit that simultaneously collects the responses from the stacked trays, simultaneously programs the stacked trays with survey questions, and simultaneously recharges a battery in each tray.

A ramming brake is provided for use with a projectile launched from the barrel of a gun having a tapered portion. The ramming brake includes a braking ring that has a tapered surface configured to wedge into a tapered portion of the gun barrel. In a particular configuration, the braking ring wedges in the tapered breach of the gun barrel. The ramming brake further includes a retaining mechanism that is used to couple the braking ring to the projectile. This retaining mechanism restrains and controls the movement of the projectile after the braking ring wedges into the tapered portion of the barrel.

An obturator is provided for a projectile launched from a gun barrel. The projectile has a mid-body annular groove that includes a shaped surface. The obturator includes an annular ring having an inner surface in contact with the shaped surface of the annular groove of the projectile. The annular ring further includes an outer surface. When the projectile is in the gun barrel, the outer surface of the annular ring contacts an inner surface of a bore of the gun barrel. The radial distance between the inner surface and the outer surface of the annular ring substantially equals or exceeds the radial distance between the shaped surface of the annular groove and the inner surface of the bore of the gun barrel at at least one point when the projectile is positioned in the barrel. This feature restricts a flow of charge gases from an aft end of the projectile to a forward end of the projectile when the projectile is launched from the gun barrel.

The present invention discloses a communication system network that comprises a plurality of communication systems and a processing multiplexer. The communication systems, which may be either conventional communication systems and/or trunked communication systems, transmit digitized audio signals and communication system data to the processing multiplexer. Based on signal destination data, which is part of the communication system data, the processing multiplexer processes the digitized signals and routes the resultant signals to the appropriate signal destinations of the communication systems.

An integrated circuit protection device for use with a voltage regulator used to drive an integrated circuit to prevent damage to the integrated circuit which goes into a "latch up" condition. The integrated circuit protection device comprises a first switching circuit, connected to the output of the voltage regulator for selectively connecting the output of the voltage regulator to ground and a second switching circuit, connected to the input and the output of the voltage regulator and to the first switching circuit, for detecting a "latch up" condition and for selectively activating the first switching circuit upon detection of a "latch up" condition, whereby the first switching circuit connects the output of the voltage regulator to ground and resets the integrated circuit to prevent damage thereto. A predetermined time after the "latch up" condition is detected, normal operation is automatically restored. In another embodiment, the first switching circuit is included in an adjustable voltage regulator, but is still controlled by the second switching circuit as described hereinbefore. In still another embodiment the protection circuit monitors the input current drawn by a voltage regulator and cuts the current thereto when the current exceeds a predetermined value caused by the "latch up" condition of the integrated circuit. The output of the voltage regulator drops to zero and clears the integrated circuit.
摘要:
The remote digital volume control system (10) as used in an audio control apparatus comprising at least one multidigital/audio slot bus (12) which is coupled to base stations through interfaces (21-24). Console interfacing circuits (38) are coupled to the bus (12) and a plurality of remote consoles (30) each with channel control panels (32) coupled to the interfacing circuits (38). The system (10) comprises channel control modules (102) and shared A/D circuitry (150) including two comparators (152, 153) and an up/down counter (154) for generating a four-bit word for each volume control setting of each channel control module (102). The remoted interfacing circuits (38) coupled to said bus include a RAM (180) for storing volume level information for each channel control module (102) and routing information, and a timing control circuit (182) for routing information from the respective digital/audio slots on the bus (12) to audio line driver circuits (71-74) in the consoles (30). The remoted interfacing circuits (38) are controlled by the RAM (180), the timing control circuit (182), and a microprocessor (36) which cause appropriate digital/audio slot information to be converted to an analog signal, muted to the desired level, and routed to a desired audio line driver circuit (71-74) coupled to a speaker (91-94) in a desired console (30).
摘要:
There is disclosed a combined business communication system and an ACD system where each station in the system is available to handle, on a per call basis, either ACD or regular incoming calls. The system is arranged to accept from any user at any station an ID uniquely associated with that user. The ID in turn then controls the ACD system to direct calls to the user in accordance with the ID information without regard to the station location of that user. Calls between system users are completed either in accordance with station identification numbers or in accordance with the ID number of the desired user.
摘要:
A duplex module for simultaneous bidirectional transmit-receive communication with the end of an optical fiber or fiber bundle. The end face of an optical fiber in optical coupling registry with one end of a common bidirectional transmit-receive optical path is tilted to divert any transmit signal back-reflected from such end out of such path. The other end of the transmit-receive path is affiliated with signal receiver and transmitter means via a beam splitter.

A rotary fiber optic waveguide coupling. Bared ends of two fiber optic waveguide cable sections are held in mutually-aligned end-to-end adjacent positions in opposite extension along a common rotary axis by a pair of ferrules having central through-openings in which such ends coextend and are bonded in close fit. The ferrules are held in precise axial position by abutment at their inner ends with annular shoulder in a pair of alignment caps mounted in two members movable relatively about such rotary axis. Retaining sleeves screwed into the relatively turnable members cooperate with washer members on the ferrules to obtain such abutment, and the ferrules project through openings in the alignment caps to obtain precise radial positioning. A friction-free rotary bearing interconnects the two relatively turnable members. The bearing is preloaded along the axis of rotation to give precise axial and radial positions of the one turnable member relative to the other.
