Patent CA-2140568-A1 (CA)
Title: Reduced bit number motion vector detection
Inventor: OGURA EIJI
IPC: H04N19/42
Filed: 1995-01-19
Abstract: In image compression using motion compensated predictive coding, the number of bits of pixel data is reduced before the pixel data are supplied to a motion vector detecting apparatus. Motion vectors are detected using a pipelined operation in which pixel by pixel differences between a reference block and a search block are obtained and summed. At each stage of the pipeline, the sum of differences is limited to a predetermined maximum number of bits.

Patent CA-2146886-A1 (CA)
Title: Fluid bed desulfurization
Inventor: CAMPBELL WILLIAM MARTIN
IPC: B01J8/08
Filed: 1995-04-12
Abstract: A method and apparatus for desulfurizing a gas and regenerating a sorbent is disclosed. The sulfur containing feed gas which can be an effluent gas from a coal gasification reactor, for example, is desulfurized with a particulated metallic oxide sorbent in a transport riser. The sulfided sorbent is than separated from a desulfurized effluent gas and regenerated by contact with an oxygen-containing gas in a transport riser. The regenerated sorbent is separated from an SO2 containing offgas and recycled to the desulfurization step. The degree of sorbent conversion in the desulfurization step is held at a low level and the sorbent regeneration rate is increased to avoid excessive temperature rise in the regeneration step. In such manner, sorbent cooling can be substantially eliminated. The regeneration riser preferably comprises a once-through lift riser to minimize the riser transport gas requirements to just oxidant gas or oxidant gas mixed with a reduced amount of diluent gas. A reduction in use of diluent gas give a relatively high offgas SO2 concentration of as much as 15 mole percent, suitable for sulfuric acid manufacture and/ or reduction to sulfur.

Abstract: There is provided a method of performing priority control for cells in an output buffer type ATM switch including a switching unit, having a plurality of input ports and a plurality of output ports, for switching/outputting the cells input from the input ports to the output ports, and a plurality of output buffer units, connected to the output ports of the switching unit, for temporarily storing the cells output from the output ports to perform output control of the cells.  A loss quality class and a delay quality class are added to each cell.  A plurality of logical queues for temporarily storing the cells are vertically set in a buffer memory in accordance with the delay quality classes and routing information.  The input cells are selectively written in the logical queues on the basis of the delay quality classes and the routing information added to the cells.  A transition process is performed for all the logical queues to change the delay quality class of each of the logical queues into one of upper and lower classes depending on a cell storage amount in the logical queue.  Upon completion of the transition process, the cells are read from the logical queue having the delay quality class which is a lowest class.
Patent CA-2149094-A1 (CA)
Inventor: DOHI TOMOHIRO
IPC: H04W52/04
Filed: 1995-05-10
Abstract: A transmission power control method of a spread-spectrum communication system which determines transmission power in accordance with a transmission power control bit.  The transmission power control bit is extracted at a base station from a signal sequence obtained by receiving a signal transmitted from a mobile station, and by despreading and demodulating the received signal.  When the same value of the transmission power control bit is consecutively received, the transmission power of the base station is controlled in accordance with transmission power control quantities which are predetermined in accordance with the consecutive number of receptions of the same value of the transmission power control bit.  This is because the consecutive receptions of the same value of the transmission power control bit suggests that the received power of the other party (the mobile station in this case) changes greatly.  Thus, an amount of an increment or a decrement in the transmission power is increased with the duration of the consecutive receptions.  This makes it possible for the transmission power control to follow sudden changes in propagation paths.

Title: Helium recovery
Inventor: D AMICO JOSEPH S
IPC: B01D53/22
Filed: 1995-10-18
Abstract: The disclosed pressure swing adsorption processes can recover helium from source streams of less than about 10 percent by volume helium and concentrate the helium to a concentration of greater than about 98 percent by volume. Two stages of pressure swing adsorption are used in series. The source of the helium gas will be natural gas wells. The source gas will contain hydrocarbons but in most instances the primary gas other than helium will be nitrogen. Each stage of pressure swing adsorption will contain a plurality of adsorbent beds, and preferably about four. In each stage the adsorbent beds will be cycled through multiple phases. In the first stage the adsorbent beds will sequentially undergo the phases of adsorption, recycle, depressurization, evacuation, helium pressurization and recycle feed pressurization. The product gas from the first stage is flowed to the second stage and in the second stage sequentially will undergo the phases of adsorption, depressurization, evacuation, purge, and helium pressurization. The offgas from evacuation and purge in the second stage is flowed to input to the first stage. The processes using an adsorbent that adsorbs the gases other than helium produces a product stream in a high volume with a helium content of more than 98 percent by volume.

Title: Method to operate a discharge lamp, and circuit arrangement for operation of the discharge lamp
Inventor: BERNITZ FRANZ
IPC: H05B41/02
Filed: 1995-10-18
Abstract: To operate a high pressure discharge lamp, and more particularly a low-power high-pressure discharge lamp, only in quiet or stable lamp operation, a microprocessor (MC) is provided which establishes a test phase of limited time duration during which the frequency of operation of the lamp is varied by frequency modulation within a predetermined range.  Lamp operation is monitored, for example by deriving a test voltage across a coupling capacitor (C6) receiving lamp current.  If the monitored voltage, which is representative of lamp operation, shows that the lamp operates quietly and stably, the then pertaining frequency is stored by the microprocessor and, after the test phase is finished, the lamp is operated within a frequency window formed by the largest number of contiguous modulation frequencies which are suitable for, or result in, stable lamp operation.  The test phase is carried out repetitively, at least upon each energization of the lamp, so that different operating characteristics of the lamp (e.g. due to changes in temperature, aging, or the like) are compensated.
