Patent CA-2335404-A1 (CA)
Title: A portable sail kit
Inventor: BLAD ROBERT CARL
IPC: B63H9/06
Filed: 2001-02-12
Abstract: A "V"-shaped sail is mounted to flexible tubular members. The tubular members are permitted to flex as wind speed increases. This lowers the effective centre of effort and the area of the sail and increases the stability of vessels and vehicles to which the sail is mounted without the need for operator involvement. The sail frame is mounted to a "Y" shaped yoke having a cylindrical stem. The stem is inserted into a locking base that permits rotation of the stem in 30 degree increments while preventing the stem from being removed from the anchor while the sail is set at an operating angle. The locking base can be mounted permanently or temporarily to the vessel and vehicle. One unique aspect of this invention is that no lines (sheets] or similar apparatus are required for any operational function of raising, lowering or sailing this sail kit.

Title: Method and apparatus for transmitting and receiving information
Inventor: ASAMI KAZUO
IPC: H04W4/90
Filed: 2001-03-14
Abstract: Information transmitted through a wireless communication system (formed by the information transmission line from the artificial satellites and the radio towers) or through wired communication systems (established by cables) is categorized into four categories according to priority. The individual information is transmitted in a broadcasting mode in synchronization with the information transmission timing defined for the individual information category. The information receiver captures and edits the received information and provides output for the service client in the manner associated with the individual information category corresponding to the received information. Category-4 information is transmitted with the highest priority immediately when the information is generated. Category-3 information is transmitted periodically, for example, every five minutes. Category-2 information is transmitted at a time slot when the transmission line is relatively unoccupied. Category-1 information is transmitted at a time slot when the transmission line is least occupied.
Patent CA-2340942-A1 (CA)
Inventor: LUNDBY STEIN A
IPC: H04B1/707
Filed: 1999-08-17
Abstract: A method for limiting peak transmit power in a CDMA communication system by transmitting a first communication signal having a first high transmit power region, and transmitting a second communication signal having a second high transmit power region. A first and a second communication signal are time offset to prevent the first and second high transmit power regions from occurring simultaneously. Time shifting only a portion of the first and second communication signals is also taught. The first and second communication signals can also include respective first and second low transmit power regions. The time offset can be selected to align one of the first and second high transmit power regions with one of the first and second low transmit power regions. The total transmit power signal can be determined and the time offset can be selected to minimize a peak level of the total transmit power signal.

Title: Data compression using adaptive bit allocation and hybrid lossless entropy encoding
Inventor: HOULE PAUL STEVEN
IPC: H04N19/124
Filed: 1997-03-19
Abstract: A method and apparatus for adaptive bit allocation and hybrid lossless entropy encoding. The system includes three components: (1) a transform stage, (2) a quantization stage, and (3) a lossless entropy coder stage. The transform stage (1) uses a wavelet transform algorithm. The quantization stage (2) adaptively estimates values for parameters defining an approximation between quantization size and the logarithm of quantization error, and recursively calculates the optimal quantization size for each band to achieve a desired bit rate. The baseband and subbands are transformed into quantization matrices using the corresponding quantization sizes. The lossless entropy coder stage (3) uses the observation that the entropy property of run lengths of zero index values in the subband quantization matrices is different from the entropy property of non-zero indices. Each quantization matrix is parsed so that each non-zero index is extracted into a separate stream, and the remaining position information is parsed into an odd stream of run length values for "0" and an even stream of run length values for "1 ". These three streams are Huffman coded separately in conventional fashion.

Title: Film type solid polymer ionomer sensor and sensor cell
Inventor: PROHASKA OTTO J
IPC: G01N30/12
Filed: 2000-11-20
Abstract: A miniaturized gas sensor including film type electrodes, and a solid ionomer (5) electrolyte, for the detection of toxic gases, i.e., carbon monoxide, and other oxidizable or reducible gases and vapors is described. The all solid planar sensor cell has two or more film type electrodes arranged on a non conductive planar surface of a supportive material. The electrodes (3, 7, 8) are discrete and in intimate contact with the same solid polymer ionomer membrane. The sensor cell contains no liquid electrolyte and is operated in a potentiostatic or potentiodynamic mode. The unique feature of the sensor cell is that high sensitivity to a select gas or vapor is achieved by a novel three-phase contact area (2) design for a sensing electrode (3) which is easily accessible to the gas sample via small diffusion openings (6) or holes that penetrate through the solid polymer ionomer membrane layer above the sensing electrode. A significant signal to background noise enhancement is achieved for these film type sensor cells by processes that increase the three phase contact area.
