Title: Transgenic plants with altered polyol content
Inventor: TARCZYNSKI MITCHELL C
IPC: C12N9/04
Filed: 1992-05-08
Abstract: Transgenic plants have been produced which have been engineered to produce physiologically significant levels of sugar alcohols, or polyols, which is not natively produced by plants of the species. Transgenic plants have been engineered to express a bacterial mannitol-1-P dehydrogenase which, in the reverse reaction in the plant cells, produces mannitol from fructose in a plant which does not natively produce mannitol. Levels of polyols in plant cells have been associated with osmotic regulation and thereby with water stress tolerance. The transgenic plants have significant research value, and, surprisingly, seem to exhibit enhanced growth rates and vigor, and stress tolerance. Another polyol-producing enzyme gene has been isolated from a stress tolerant plant.

Patent CA-2093228-A1 (CA)
Title: Cdma subtractive demodulation
Inventor: DENT PAUL W
IPC: H04W88/00
Filed: 1992-07-31
Abstract: Subtractive CDMA demodulation optimally decodes a coded information signal embedded in many other overlapping signals making up a received, composite signal. A radio receiver correlates a unique code corresponding to the desired signal to be decoded with the composite signal. Moreover, after each information signal is successfully decoded, it is recoiled and removed from the composite signal. Subtractive CDMA demodulation is enhanced by decoding the composite signal in the order of strongest to weakest signal strength.      The individual information signals are spread using block error correction codes which are correlated with the composite signal using Fast Walsh transforms. Correlated signals identified as the largest transform component are removed from the composite signal and the remaining composite signal is reformulated using an inverted Fast Walsh transform. Any residual error or interference caused during the extraction of a transform component is removed by correlating the composite signal using the index of that transform component.

Title: Multirate, Sonet-Ready, Switching Arrangement
Inventor: PAWELSKI ROBERT L
IPC: H04Q3/52
Filed: 1993-08-24
Abstract: A time-division multiplex switch (100) switches a hierarchy of data rates. It sets up higher-rate connections not as a plurality of individual lowest-rate connections but as one or more time slots in each one of a plurality of sequential frames (40, 50) that correspond to that higher rate in each superframe (30). A time-slot-interchange switching element (131, 141) of the switch utilizes a plurality of physically or logically distinct double-buffered data memories (301,302, 303) each corresponding to a different one of the superframe and different-size ones of the frames. Reading and writing of each of the data memories' buffers alternates with the corresponding one of the superframe and different-size frames; reading of a data memory's buffer immediately follows writing of that buffer. Information from all incoming time slots is written into each one of the data memories, but only information corresponding to the data rate of an individual data memory's corresponding frame size is read from that data memory into outgoing time slots. A control memory (305) maps memory locations of the data memories to output time slots. A corresponding control architecture in a switching element (1700) of a time-multiplexed switch (120) uses a control memory (1701) that maps input ports to time slots of an output port. <IMAGE>
