Patent CA-2258358-A1 (CA)
Title: Low power multiplier for cpu and dsp
Inventor: NICOL CHRISTOPHER JOHN
IPC: G06F7/52
Filed: 1999-01-11
Abstract: The NEG output of the Booth encoding circuit and the multiplicand input are gated so as to minimize switching activity in the multiplier without adding any delay to the critical path thereof. Advantageously, power consumption in the multiplier is significantly reduced, e.g., on the order of 90%, when multiplication is in fact not being performed. Additionally, by changing the structure of the last XOR gate of the partial product generation circuit, the need to gate the multiplicand input can be eliminated. Advantageously, this eliminates the extra circuitry which would otherwise be required to gate the multiplicand input, thus reducing cost. Furthermore, additional power savings may be achieved by efficiently resynchronizing the multiplicand input with the Booth encoded input to the partial product circuit.
Patent CA-2262619-A1 (CA)
Title: Multiple-phase electric machine with a space-optimised turn-to-turn winding
Inventor: HILL WOLFGANG
IPC: H02K3/12
Filed: 1997-08-01
Abstract: Known turn-to-turn windings with overlapping, sinuous conductor strands either only insufficiently use the slot space or are difficult to produce. In addition, no uniform distribution of the current intensity is achieved in the winding head space. The disclosed multiple-phase conductor layers are made of identical conductor strands located in the slot space at the same distance from the air gap surface. The conductor layers superimposed in the slots supplement each other in the use of the winding head space in that they lead the current in opposite directions across the width of the slot. A uniform distribution of the current intensity and a high space utilisation are achieved in that the layered winding heads are offset relative to the layers in the slot in the direction of the slot depth by half the height of a layer. Each conductor strand occupies two winding head layers when crossing the winding heads, the layers being exchanged at about the centre of the connection section at the outside of the winding heads. Alternating second conductor layers in succession are directly interconnected. Engines and generators equipped with space-optimised turn-to-turn windings are characterised by a high effectiveness and power density.

Title: Elastic laminates with improved hysteresis
Inventor: SHAWVER SUSAN ELAINE
IPC: B32B7/022
Filed: 1997-09-04
Abstract: A composite elastic material (40) is provided having improved hysteresis comprising a layer of an elastic material (32) bonded to a layer of nonelastic material (12) at least one side. The elastic material layer is made from a blend of a narrow polydispersity number polymer and a conventional elastomer, and the blend is essentially free of low molecular weight polyethylene processing aids. The composite elastic material laminate (40) should have a hysteresis at least 15 percent better than a similar laminate made without the narrow polydispersity number elastomer but with the processing aid.
Patent CA-2268078-A1 (CA)
Title: Thermally responsive coupling for fluid-carrying lines
Inventor: MUMMERT THOMAS A
IPC: F16K17/38
Filed: 1997-10-15
Abstract: A fluid coupling (60) for connecting fluid conduits includes a thermally sensitive member (30) and a coupling nut (40) which fit together for conjoint operation. The thermally sensitive member (30) has a resiliently expanded end (36) which engages a cooperating structure (14) on a fluid-carrying member (10) to retain it in place while permitting relative rotation. The thermally sensitive member (30) has a flange portion (34) that, when assembled, is in axial shear between the coupling nut (40) and the fluid-carrying member (10).  When exposed to excessive temperature, the flange portion (34) softens, allowing the fluid-carrying member (10) to move and an in-line valve to close, thus shutting off the flow of gas. In another embodiment, the thermally sensitive member (84) is a bushing that is received within the plug body (80) of a quick-disconnect type coupling. This thermally sensitive bushing is held in axial shear between a different type of fluid-carrying member (82) and an internal shoulder (100) of the plug body (80). When exposed to elevated temperature, the bushing softens to allow the fluid-carrying member (82) to move inside the plug body (80), thus permitting a valve member within an adjoining coupling to shut off fluid flow.

Title: Soft decision output decoder for decoding convolutionally encoded codewords
Inventor: SINDHUSHAYANA NAGABHUSHANA T
IPC: H04L1/00
Filed: 1997-11-06
Abstract: A soft decision output decoder (20) and decoding method. The decoeder (20) decodes a sequence of signals output by an encoder (12) and transmitted over a channel (17). The soft decision output decoder (20) includes a first "generalized" Viterbi decoder (24) for decoding the sequence of signals received over the channel during a forward iteration through a trellis representing the encoder output having a block length T. The first "generalized" Viterbi decoder (24) begins at an initial state to and provides a plurality of forward iteration state metrics a for each state at each time interval over a window of length 2L, where L is on the order of a few constraint lengths and 2L is less than a block length T. A second "generalized" Viterbi decoder decodes the sequence of signals received over the channel (17) during a backward iteration through the trellis. The second decoder (26) starts at a second time t2L and provides a plurality of backward iteration state metrics .beta. for each state at each time interval. A processor (28) then performs a dual maxima computation at each state using the forward state metric, the backward state metric and the branch metric for same to provide a measure of the likelihood that a particular sequence of data was transmitted by the encoder (12). By performing forward and backward Viterbi decoding with dual maxima computations at each node within a window moved over the treillis, the inventive decoder (20) provides the performance benefits associated with a LOG-MAP decoder while avoiding the excessive memory requirements of same.

Title: Method and apparatus for collecting and transferring refuse
Inventor: MARTZ ERLE FREDERICK
IPC: B65F1/14
Filed: 1999-11-10
Abstract: A method and apparatus for collecting and transferring refuse to a transportation truck for hauling to its ultimate disposal site, such as a landfill. The apparatus comprises a refuse collection and transfer container movable between a first, lowered position and a second, raised position. When the container is in the raised position and the transportation truck is underneath, transfer of the collected refuse is accomplished by opening angled, retractable bottom doors on the container. The bottom doors allow for the regulation of the amount of refuse transferred to the truck, thus ensuring a full load within the truck while at the same time preventing spillage. The movement of the container and the doors may be powered by the hydraulic system of the truck and controlled by a control panel on the apparatus. The apparatus may be partially below ground level.

Title: Robotic containerization and palletizing system
Inventor: WATSON THOMAS
IPC: B65G61/00
Filed: 2000-03-14
Abstract: A robotic containerization and palletizing system having a multiple-fingered end effector. The system includes a frame that defines one or more cells. Each cell has one gantry-type robot, which is mounted in a set of tracks on top of the frame. The robot is movable along two axes and has an arm to which the end effector is mounted. The end effector is designed to grasp trays, tubs, and similar items from a conveyor system running through the; cell and load them in a cart or on a pallet. The items are gripped by two sets of fingers. One set of fingers may be mounted to a first plate and another set of fingers may be mounted to a carriage that moves in a horizontal direction, either toward or away from the first set of fingers. Each finger has a main shaft and a bent tip. The shafts are rotatable such that the tips can be moved underneath or out from under a load, depending upon whether a pick-up or drop-off operation is being performed. The end effector is designed to carry out top loading of carts and pallets and includes a measurement and containment plate that is used to detect and measure the height of trays and tubs placed in carts and on pallets. The measurement and containment plate also helps prevent loose mail in unsleeved trays or tubs from falling out of the trays or tubs during robotic transportation. The downward force exerted on the top of the mail tray/tub also helps maintain the grip of the fingers. In order to load carts having shelves, the gripper may also include a shelf lowering assembly.
