Patent CA-2501188-A1 (CA)
Title: Combinatorial protein library screening by periplasmic expression
Inventor: IVERSON BRENT I
IPC: G01N33/554
Filed: 2003-07-15
Abstract: The invention overcomes the deficiencies of the prior art by providing a rapid approach for isolating binding proteins capable of binding small molecules and peptides. In the technique, libraries of candidate binding proteins, such as antibody sequences, are expressed in the periplasm of gram negative bacteria and mixed with a labeled ligand. In clones expressing recombinant polypeptides with affinity for the ligand, the concentration of the labeled ligand bound to the binding protein is increased and allows the cells to be isolated from the rest of the library. Where fluorescent labeling of the target ligand is used, cells may be isolated by fluorescence activated cell sorting (FACS). The approach is more rapid than prior art methods and avoids problems associated with the outer surface-expression of ligand fusion proteins employed with phage display. The inventors have also provided improved antobodies that were initially prepared using the sceening methods developed.

IPC: H04W48/18
Filed: 2003-06-23
Abstract: A method and apparatus for packet data service discovery are described. A  current blacklist comprising entries for wireless networks not providing packet data services (i.e. either not supporting the services or not having a packet data services roaming agreement) is kept in memory of the mobile device based on previous attempts to connect to such networks. Current preferred roaming lists identify whether a given wireless network can be acquired, but do not identify whether a data services roaming agreement exists. At least one of the following advantages is provided: no advance knowledge of data services roaming agreements is required; no mobile device software change is required when the data services roaming agreement changes; mobile device can notify a server of a wireless network status change; significant power savings at the mobile device; and avoid unnecessary network access, which in turn saves network resources and capacity.

Patent CA-2515689-A1 (CA)
Title: Enhanced efficiency feed forward power amplifier utilizing reduced cancellation bandwidth and small error amplifier
Inventor: VASSILAKIS BILL
IPC: H03F1/32
Filed: 2004-02-11
Abstract: A feed forward power amplifier is disclosed which utilizes three signal cancellation loops. Loop 1 includes a main amplifier (215) and is used to derive a carrier cancelled sample of the main amplifier output. Loop 2 includes an error amplifier (400) used to amplify the carrier cancelled signal derived from Loop 1 operation in order to cancel distortion products generated due to the nonlinear nature of the main amplifier (215). Loop 2 also utilizes a very short Loop 2 delay line (225). A significant efficiency gain is provided due to reduced output power losses associated with the Loop 2 delay line (225). Lower output losses also results in lower distortion levels produced by the main amplifier (2.15). This, in turn, reduces the size and performance requirements placed on the error amplifier (400). A smaller and more efficient error amplifier (400) is employed resulting in further amplifier system efficiency improvement. A spurious signal detector (805) for out-of-band distortion detection and an associated microcontroller (810) for Loop 1 and Loop 2 control are also provided. A third signal cancellation loop is utilized to sample the amplifier output and reduce the carrier level of the signals sampled at the output of the amplifier before providing the sampled output to the spurious signal detector (805). By significantly reducing the carrier power level relative to distortion power levels a cost effective spurious signal detector (805) can be utilized. This also provides a faster conversion time in Loop 2 cancellation and enhanced cancellation of out-of-band distortion products due to a greater useful dynamic range available for the DSP (817) employed in the spurious signal detector (805).

Abstract: An engine decompression system that can secure a projecting height of a decompression cam from a base face of a valve operating cam to be relatively large in an engine starting rotational region, and maintain a state in which the projection height is decreased in a complete combustion rotational region of the engine.  The decompression system includes a decompression cam shaft provided on a valve operating cam shaft or a rotating member integrally coupled thereto, the decompression cam shaft being capable of rotating between an operating position in which a decompression cam projects above a base face of a valve operating cam to slightly open engine valves during a compression stroke and a release position in which the decompression cam is withdrawn to allow the engine valves to close.  A centrifugal mechanism connected to the decompression cam shaft maintains the decompression cam shaft at an operating position in a starting rotational region, and rotates the decompression cam shaft to the release position in a normal running region. The centrifugal mechanism is arranged so that, in a complete combustion rotational region between the starting rotational region and the normal running region, the decompression cam shaft is maintained at a middle position at which the projection height of the decompression cam is less than the projection height at the operating position.
