Abstract: A method for transmitting and receiving signals using multi-band Radio Frequencies (RFs) is provided.  The method transmits an information unit of a specific layer above a physical layer through a plurality of frequency allocation bands managed by the specific layer and transmits control information identifying each of the plurality of frequency allocation bands. The control information identifying each of the plurality of frequency allocation bands includes a second ID into which a first ID has been converted, the first ID identifying each of the plurality of frequency allocation bands in the physical layer, the second ID  identifying each of the plurality of frequency allocation bands managed by the specific layer in the specific layer. To accomplish this, a timing offset is applied to the entirety of a frame or to a preamble (synchronous channel) so that the timing offset is used as the ID. Applying a timing offset to the entirety of a frame or to a preamble (synchronous channel) can achieve an advantage of PAPR reduction.

Patent CA-2715790-A1 (CA)
Inventor: RAGSDALE CHARLES W
IPC: C12N13/00
Filed: 2009-02-11
Abstract: An electroporation cuvette is constructed with electroporation electrodes arranged in non-parallel relation to form a gap whose width varies with the location within the cuvette, plus a pair of positioning electrodes that are arranged to cause electrophoretic migration of biological cells within the cuvette according to cell size.  Once the cells, suspended in a solution of the impregnant, are distributed in the cuvette by the positioning electrodes, electric field pulses are generated by the non-parallel electroporation electrodes. Because of their distribution in the cuvette, the various cells will experience voltage differentials across their widths that approach uniformity regardless of cell diameter, since the larger cells will be positioned at locations where the gap between the electrodes is greater and the smaller cells at locations where the gap is relatively small while the voltage drop across the entire gap is uniform along the length of the cell. The voltage differential across the width of the cell is thus roughly paired with the cell diameter, and this reduces the disparity in voltage differential that cells of different sizes would otherwise experience with parallel electrodes.
Patent CA-2716251-A1 (CA)
Title: Tissue sample preprocessing methods and devices
Inventor: RAMACHANDRAN IYER ESWAR PRASAD
IPC: G01N1/28
Filed: 2009-02-20
Abstract: To preprocess a tissue sample, a first permeable mesh membrane is tautly stretched out over the tissue sample and overlaid on top of a flat surface. This covering sandwiches and secures the tissue sample in between the first permeable mesh membrane and the flat surface. If it is desired to reinforce the mechanical strength of the first permeable mesh membrane, a second permeable mesh membrane can be tautly stretched out and overlaid on top of the sandwich. Alternatively, the second permeable mesh membrane can be attached onto a third component, such as a disposable solvent resistant frame, to create a framed mesh. Thereafter, the first permeable mesh membrane may be attached to the framed mesh to create a compound framed mesh. The tissue sample may then be sand-wiched and secured in between the compound framed mesh and the flat surface. To retain and flatten the tissue sample, gentle pressure may be uniformly applied.

Title: System for managing mobile internet protocol addresses in an airborne wireless cellular network
Inventor: LAUER BRYAN A
IPC: H04W92/02
Filed: 2009-03-05
Abstract: The Aircraft Mobile IP Address System provides wireless communication services to passengers who are located onboard an aircraft by storing data indicative of their individually identified wireless devices. The System assigns a single IP  address to each Point-to-Point Protocol link which connects the aircraft network to the ground-based communication network but also creates an IP subnet onboard the aircraft. The IP subnet utilizes a plurality of IP addresses for each Point-to-Point link thereby to enable each passenger wireless device to be uniquely identified with their own IP address. This is enabled since both Point-to-Point Protocol IPCP endpoints have pre- defined IP address pools and/or topology configured. Such an approach does not change IPCP or other EVDO protocols/messaging but allows this address to be directly visible to the ground-based communication network.

Abstract: Combinations of catalyst and compound are described that are suitable for use in a thermally regenerative fuel cell. Such combinations offer greater than 99%  selectivity and accordingly they cycle through a reversible dehydrogenation process with substantially no loss due to byproduct formation. Combinations of secondary benzylic alcohols and Pd/SiO2 catalysts offer levels of by-products that are undetectable by NMR and GC  analysis. With such TRFC, thermal energy can be converted into electric energy in a moving vehicle without the requirement of storage of H2, and its safety issues. Instead, a catalytic amount of H2 is cycled through the system and used to generate electric energy.
