Title: Method for operating a wireless telecommunications system
Inventor: KHANNA SANJEEV
IPC: H04B7/26
Filed: 1999-03-02
Granted: 2003-04-08
Abstract: A method for operating a wireless telecommunications system whereby communication channels are efficiently allocated to cells of the system is provided. In accordance with an illustrative embodiment of the present method, call demand information is obtained for each cell in the wireless system and converted to a channel demand. Once the channel demand for each cell is known, a tentative channel allocation is performed. Call demand information can be obtained as frequently as desired to update channel allocation throughout the wireless system. In some embodiments, the method for channel allocation described herein can be used alone to allocate channels. In other embodiments, the present method for channel allocation can be used on an hourly, daily, or other temporal basis, as appropriate, to provide a channel allocation which is then updated on a substantially continuous basis by any conventional dynamic channel allocation scheme. To allocate channels, an "interference graph" that relates interfering cells to one another is defined. When nearest-cell interference is considered, an initial step is performed wherein three channels are iteratively allocated to all cells in the system to remove all groupings within the interference graph comprising three mutually-interfering cells.  During the initial step, the allocation of three channels reduces channel demand by one in every cell.  Once the interference graph is free of such three-membered groupings, channel demand is reduced more efficiently wherein no more than five channels are allocated to satisfy two units of channel demand. To do so, a decomposition/reconstruction operation is performed wherein the interference graph is segregated into groupings of cells to which channels are allocated. The operation for allocating channels to cells when nearest- and next-to-nearest-cell interference is considered does not use the initial step of allocating three channels. It does, however, proceed in a manner analogous to the decomposition/reconstruction process mentioned above, although the operation is performed on a cell-by-cell basis, rather than with groupings of cells.

Abstract: A yarn feeder device for feeding elastic (soft) yarns to a yarn consuming station whose yarn demand fluctuations over time has a control unit which ascertains the current yarn demand or to which the current yarn demand is reported. In accordance with this demand, a yarn feed wheel is driven at a rotary speed suitable for the yarn demand. The yarn travels via a tensioning device to the yarn feed wheel. The tensioning device is arranged such that the yarn is stretched in a defined way. As a result, a fixed association between a desired yarn feed quantity and the rotary speed of the yarn feed wheel is possible.

Title: Spray chamber with dryer
Inventor: FRENCH JOHN B
IPC: G01N27/62
Filed: 1997-12-22
Granted: 2004-11-23
Abstract: A spray chamber for producing a sample for an analyzer which may contain a plasma torch. In the chamber, a heated sheath gas is fed into the periphery of the spray surrounding the spray, adjacent the origin of the spray, thus reducing the size of droplets which are recirculated, thereby reducing agglomeration of the droplets and promoting rapid drying of the spray. Preferably all of the spray solvent is evaporated in a very short chamber, thus further reducing the amount of spray recirculated, and all of the combined flow of dried particulates from the spray, nebulizing gas and sheath gas is directed into the torch. In one embodiment, the central core of the combined flow is directed to the torch and the peripheral portion of the combined flow is ducted to waste. In another embodiment the aqueous spray solvent is fully evaporated before it leaves the spray chamber, and the combined flow is directed through a membrane dryer before reaching the torch, to remove most of the water vapor from the flow and thus to reduce water vapor loading on the torch.

Abstract: A demodulator (1) produces I and Q symbol streams from a received PSK signal which is a time-multiplexed signal composed of a 20-symbol-long BPSK frame sync signal, a 20-symbol-long BPSK superframe identification signal, and an 8PSK digital signal. BPSK demappers (3) produce bit streams B0-B3 demapped according to a base criterion, which allows signal points to be the same along the Q-axis in the I-Q phase plane, and to criterions obtained by shifting the base criterion counterclockwise by .pi./4, 2.pi./4 and 3.pi./4. First comparators (60-63) capture, from the bit streams B0-B3, patterns being different few bits at most than the frame sync signal. A predetermined time later, second comparators (64-67) capture patterns being different few bits at most than the superframe identification signal. A frame sync capture signal (SYN) is then produced by a generator (90).
