Title: Intrusion alarm sensing unit
Inventor: CECIC DENNIS
IPC: G08B29/02
Filed: 1991-10-29
Granted: 1997-11-18
Abstract: The present invention is directed to an intrusion detection system having two different types of motion sensors and processing of the signals produced by the motion sensors in a manner to provide a reliable indication of motion within the space being sensed.  The intrusion detection system includes a microprocessor and produces an alarm signal if each sensor is activated within a predetermined time period of each other.  The unit is also capable of producing what is referred to as a "trouble" signal, based upon a certain number of unconfirmed event signals, i.e. a signal from only one sensor being received, within a predetermined time, indicating that one of the sensors is not operating properly.  Once a certain number of unconfirmed event signals are received, the unit operates in one of at least two different default modes whereby a trouble signal or trouble signal and alarm signal are produced by means of a different logic processing step. The invention is also directed to an intrusion detection system having dual sensors where the user can automatically reset the unit should the system have gone into default mode operation.  This is particularly useful in that it reduces service on the units and also provides an easy, convenient manner for the user to restore the device to normal operation when required.

Title: Single faceted round back wire, oblique crimp connecting rod woven wire conveyor belt
Inventor: ESTERSON CHRISTOPHER D
IPC: B65G15/54
Filed: 1991-12-04
Granted: 1999-05-04
Abstract: Wire stock for connecting rods is run through the nip of a pair of obliquely toothed rolls having teeth which taper from one face of the roll towards the other, and have a larger radius at the tip than along the portions flanking the tip.  The angle of obliqueness matches the angle that a turn of a spiral wire will traverse the connecting rod. Round wire stock for the single-faceted spiral wires is run through the nip of a pair of rolls one of which has a cylindrical surface (i.e., a flat longitudinal profile), and the other of which has a circumferential groove with a slightly larger diameter than the round wire stock.  As the wire is flattened on one side, its curved side is broadened. As the resultingly single-faceted round wire is wound into flattened spiral form, it is spatially orientationally guided, so that the facet becomes located facing outwards.  The rods and flat spirals are conventionally assembled with one another and secured to one another at respective ends, to provide a balanced flat spiral woven wire conveyor belt with rounds of turns nested in concave oblique crimp notches on the connecting rods.

Title: Apparatus and method for a synchronous, high speed, packet-switched bus
Inventor: SINDHU PRADEEP S
IPC: G06F13/362
Filed: 1991-12-30
Granted: 2001-05-29
Abstract: A high speed, synchronous, packet-switched inter-chip bus apparatus and method for transferring data between multiple system buses and a cache controller. In the preferred embodiment, the bus connects a cache controller client within the external cache of a processor to a plurality of bus watcher clients, each of which is coupled to a separate system bus. The bus allows the cache controller to provide independent processor-side access to the cache and allows the bus watchers to handle functions related to bus-snooping. An arbiter is employed to allow the bus to be multiplexed between the bus watchers and cache controller . Flow control mechanisms are also employed to ensure that queues receiving packets or arbitration requests over the bus never overflow. A default grantee mechanism is employed to minimize the arbitration latency due to a request for the bus when the bus is idle.

Title: Rotate/translate conveyor module
Inventor: TERPSTRA PAUL D
IPC: B65G13/10
Filed: 1992-10-21
Granted: 1997-02-25
Abstract: A rotate/translate conveyor module enables a workpiece to be selectively rotated and translated between adjacent sections of a conveyor without having to be lifted above the plane of the adjacent conveyor sections.  The rotate/ translate conveyor module comprises a plurality of roller modules that are arranged along the path of the workpiece.  Each roller module has at least one roller that is driven by an independent electric motor.  The rollers of the roller modules support the workpiece in the same plane as the rollers of the conveyor sections.  In one embodiment, four roller modules are symmetrically located about the workpiece path, with the longitudinal axes of the rollers intersecting at 90 degrees and at a point on the workpiece path.  By operating the electric motors in different combinations of directions, four translational and two rotational motions can be imparted to the workpiece.  The conveyor module is thus able to accept a workpiece from an adjacent upstream conveyor section and selectively reorient it by rotating it on the conveyor module and then translate the workpiece downstream to an adjacent downstream conveyor section.  The downstream conveyor section may be in line with the adjacent upstream conveyor section, or it may be perpendicular thereto.  Side guide mechanisms guide the workpiece as it is translated along the conveyor module.          Center guide mechanisms prevent translation of the workpiece during rotation thereof on the rollers.
