Title: Method and apparatus for a remote signaling and call processing in a telecommunications network
Inventor: BRUNO RICHARD J
IPC: H04L29/02
Filed: 1999-04-19
Granted: 2007-06-19
Abstract: Telecommunications switching systems that require real-time computer control can be controlled using remotely located computers coupled to the switching systems via data links. By coupling several switching systems to one or more centrally located control computers, maintenance staffing can be reduced while increasing overall system reliability by providing back up control computers in multiple centralized locations. Centrally located control computers can be backed up with redundant computers at the central control site.

Abstract: A method of processing a video stream, involves contemporaneously selecting first and second pairs of frames in the video stream with a predetermined period. The second pairs of frames have a longer period than the first pairs. For each of the first and second pairs of frames, there is determined a difference value representing the number of pixels whose value has changed between the first and second frames of the pair. A particular logic level is generated depending on whether this difference value exceeds a predetermined threshold. The generated logic levels are then compared with a decision map to identify cuts in the video stream.

Abstract: Clamps are provided for shortening a venetian type blind to fit windows of different lengths. The clamp has two portions connected by hinge. The two portions are fastened together on a lift cord and ladder below the slat at the desired shortened length. At least two clamps are used to shorten the blind. After the clamps are applied the blind is shortened by removing that portion of the blind below the clamps.  This can be done by releasing each lift cord from the bottomrail and pulling the lift cord from the bottomrail through the slats to be removed. The excess slats are removed. Then the ladders are detached from the bottomrail, shortened and reattached to the bottomrail. The lift cords are then reconnected to the bottomrail and the clamps are removed. Alternatively, the clamps which grip the ladders and lift cords can be attached to the bottomrail.

Abstract: A variably reflective display device amenable to mutiple pixel display applications. Each pixel has at least one element (10) having a reflective state in which incident light undergoes total internal reflection, and havin g a non-reflective state in which total internal reflection is prevented. Such  prevention is achieved by interfering with (scattering and/or absorbing) the  evanescent wave adjacent the surface of the element. For example, a member (18) can be positioned adjacent the element and deformed between first and second positions. In the first position a gap (20) remains between the membe r and the elememt to allow the evanescent wave to behave normally. In the seco nd position the member is in optical (but not atomic) contact with the element,  such that the member interferes with the evanescent wave and thereby prevent s total internal reflection. In one embodiment, each pixel is a grouping of retro-reflective elements (12A, 12B, 12C...) such as corner reflectors. An elastomeric material (18) is provided adjacent each grouping. If a gap (20) is left between the grouping and the elastomeric material, the grouping continu es to exhibit total internal reflection. But, if the elastomeric material makes  optical contact with the grouping, the evanescent wave is absorbed or scattered and hence total internal reflection is prevented, which in turn prevents reflection of incident light. Thus, the "pixel" formed by the corne r reflector grouping is "off" if it makes optical contact with the elastomeric  material, and "on" if a gap is left between the two.

Title: Method and means for controlling the variations in weight of extruded sausages
Inventor: KOBUSSEN MART
IPC: A22C11/02
Filed: 1999-07-14
Granted: 2004-05-04
Abstract: A conveyor assembly for moving an extruded strand of sausage (26) from an extruding machine (10) and for coagulating the outer surface (28) of the strand (26) has first (48) and second (49) conveyor elements mounted on a frame (36). The conveyor assembly on the frame (36) moves from a point of beginning (38) to a discharge station (40) and thence back to the point of beginning (38). A brine fluid circuit is disposed on the frame above the conveyor with a plurality of discharge nozzles thereon to spray brine on a strand of sausage moving with the conveyor assembly. A pair of laser lights (88) project beams (90) on the unlinked strand (26) to determine the diameter thereof. A signal is sent from the lasers to a controller (92) who compares the diameter of the strand to a predetermined diameter. The controller controls a meat emulsion pump (14) and causes it to increase or decrease its meat discharge rate to compensate for variations in diameter, and hence weight, between the measured strand and the predetermined strand on file in the controller.

Abstract: With previously known riveting methods for joining a pile of plate-shaped work pieces, material of a work piece lying on the outside is pulled through pre-drilled holes of the other work pieces and subsequently the part of the rim hole protruding out over the latter work piece is flanged. A disadvantage with this is that separate pre-drilling of work pieces is complicated and expensive. The new process is supposed to reduce the number of work steps, make the individual work steps easier and thus make the process less expensive and more effective. In addition, the connection is supposed to be accomplished flush to the surface. According to the invention, in a single feed movement of a rim hole punch, both the rim hole is formed from the one work piece as well as the openings in the other work pieces by breaking out one or more pieces of material.      Producing a rim hole.

Abstract: A piezoelectric micropump (10) is disclosed for pumping fluid from a container (14) to a delivery point in low volumes and at controlled flow rates. The pumping action is created by movement of two or three diaphragms (40, 42, 44). The movement of each diaphragm is caused by expansion and contraction of an attached piezoelectric actuator (46, 48, 50). Coordination of the movement of the diaphragms (40, 42, 44) creates unidirectional flow of the fluid. The piezoelectric actuators (46, 48, 50) are cantilevered between the pump body (22) and the diaphragms (40, 42, 44) to provide greater deflection of the diaphragms (40, 42, 44).  The piezoelectric actuators (46, 48, 50) preferably are piezoelectric bimorphs such that the diaphragms (40, 42, 44) can function as both seals and pumps.
