Patent CA-2260141-A1 (CA)
Inventor: LEIJONBERG GUNNAR
IPC: F02B75/32
Filed: 1997-07-10
Abstract: The present invention is for the kind of power machine, engines, pumps or compressors which have two or more pistons which work against each other preferably with a common combustion space or corresponding in a stationary cylinder, and where the power is transmitted to or from a rotating motion without an intermediate crankshaft. Independent of whether the machine works as engine, pump or compressor there is a need to cool the cylinder. For applications such as engines for lawn-mowers and power saws the engines must be air-cooled as in practice it is not possible to arrange a water-cooling system. Cooling of the cylinder is obtained by that holes or channels (30, 31) are arranged both in the rotating and the stationary discs and cooling air is made to flow through these channels. In order to further improve the cooling the outside of the cylinder may have flanges. In other embodiments of the invention the connecting means between the rotating disc and the outgoing shaft are so shaped that they also function as fan blades (34-35) and cause a desired air flow.

Title: Method and apparatus for transporting ds-x signals through a packet network
Inventor: GULLICKSEN JEFFREY T
IPC: H04L12/56
Filed: 1999-04-30
Abstract: A method and apparatus for efficiently transporting DS-X traffic in packet form over an ATM or other packet network. Specifically, virtual connection or slot provisioning and/or cell concentration techniques are used to compact the amount of DS-X traffic broadcast between communications system devices such as the access mux and the communications switch and spare bandwidth. In provisioning, a configured DS-X loading of an end node supporting DS-X traffic is ascertained.  In turn, a minimum number of virtual connections for bearing packetized DS-X traffic are established, either at communications system configuration or as needed. In concentration processing, a dynamic association between the virtual connections and the DS-X traffic is established, typically on a per frame basis. Only those digital channels entering the node within a given time frame which actually bear DS-X  traffic will be assigned a slot within packet. Concentration may be augmented by provisioning to further reduce bandwidth requirements. In other disclosed aspects, permanent virtual channels or PNNI soft permanent virtual connections may be used for the virtual connections where ATM is chosen as the transport protocol.

Patent CA-2278376-A1 (CA)
Inventor: JONES RAYMOND K
IPC: H04N21/43
Filed: 1999-07-22
Abstract: Synchronization among digital video and digital audio signals is maintained in a multimedia player with limited or highly varying processing power. In an exemplary embodiment of the invention, a processor with stored program memory controls the decoding and playback of audio blocks and video frames, each stream independently stored in an order of intended playback time. The processor gives priority to the decoding and playback of audio blocks, and periodically determines whether a backlog of encoded video frames exists.  Under video backlog conditions, the processor reduces the backlog by decoding only those backlogged video frames that must be decoded in order to decode and play the frame in the sequence of backlogged video frames with the latest intended playback time. After decoding this latest backlogged frame, the processor directs it to be played. Normal video decoding and playback then resumes for video frames following this latest backlogged video frame in sequence and in intended playback time.

Abstract: The sustainable plasma fusion process is a process where nuclear fusion is sustained in a reactor or reaction chamber for extended lengths of time. It can be used to generate electricity or it can be used in a fusion rocket engine.      For the nuclear fusion of hydrogen, the process works by injecting the hydrogen into a helium plasma or another plasma which has a higher fusion temperature than the hydrogen being fused. The reaction can be sustained by continously injecting more hydrogen into the plasma of a higher fusion temperature.

Title: Apparatus and method for treating ventricular tachyarrhythmias
Inventor: ZIMMER WILLIAM L
IPC: A61N1/362
Filed: 1998-04-17
Abstract: A system and method for selectively treating a ventricular tachycardia based on sensed atrial and ventricular intervals from the patient's heart. A detection window of the ten most recent atrial and ventricular intervals are analyzed for the occurrence of either tachycardia or fibrillation. When a majority of the sensed intervals are satisfied, the apparatus starts a duration time interval. Ventricular intervals and atrial intervals are compared if the ventricular interval is greater than the atrial interval by a bias factor the system delivers tachycardia therapy to the heart. Alternatively, the method withholds tachycardia therapy to the heart when the atrial rate is classified as atrial fibrillation and the ventricular response is unstable.
