Patent CA-2422410-A1 (CA)
Inventor: KURATA MASHU
IPC: F02B75/02
Filed: 2003-03-18
Abstract: A variable compression ratio engine includes a support shaft positioned eccentrically relative to rotating shafts. A restricting projection is provided at one location in the circumferential direction on the rotating shafts so as to project outward in the radial direction. A rocker member has a pair of engagement portions with respective phases displaced from each other and which engage the restricting projection. The rocker member is spring-biased in a direction in which one of the two engagement portions engages the restricting projection and is mounted on a shaft member so as to be able to rock around the axis of the shaft member. An actuator is driven by the engine negative pressure and is connected to the rocker member so as to swing the rocker member in a direction opposite to the spring-bias direction.

Title: Method of and system for mobile station abbreviated point-to-point protocol negotiation
Inventor: DYKE ERIC
IPC: H04L12/56
Filed: 2002-01-16
Abstract: Point-to-point protocol (PPP) negotiation in a wireless communication system between e.g. a mobile station (MS) and a packet data service node (PDSN). The MS sends to the PDSN a link control protocol option designated option X that identifies a user profile including at least one pre-negotiated PPP parameter.  If the PDSN supports the user profile and the at least one parameter, it acknowledges this. In response, the MS acknowledges its acceptance. Then each node sets a state machine in accordance with the user profile. If the PDSN  supports the user profile but not one or more of the at least one parameter, it sends a negative-acknowledgment identifying a second, acceptable user profile. If the PDSN does not support the user profile, it rejects the first user profile and a full PPP negotiation is performed without reference to any of the pre-stored user profiles.

Title: Information data multiplex transmission system, its multiplexer and demultiplexer, and error correction encoder and decoder
Inventor: YAMASAKI SHOICHIRO
IPC: H03M13/00
Filed: 1998-06-19
Abstract: A multiplexing unit on the transmitting side estimates information amounts supplied from respective signal processing units, determines a multiplex code on the basis of respective information amounts, derives a parity of the first determined multiplex code to form a second multiplex code, adds a CRC to each of the multiplex codes to generate two headers H1 and H2, takes out information data of respective media according to the multiplex codes, incorporates the information data into a packet together with the two headers H1 and H2, and outputs the packet. If error correction of H1 is impossible on the receiving side, error correction decoding is conducted by using the header H2. If error correction of H2 is also impossible, error correction decoding is conducted collectively for H1 and H2.

Title: Recombinant adeno-associated virus-mediated gene transfer via retroductal infusion of virions
Inventor: SCOLLAY ROLAND
IPC: A61K38/48
Filed: 2002-03-14
Abstract: Methods for introducing recombinant adeno-associated virus (rAAV) virions intro a cell or cells of a secretory gland are described. Recombinant AAV  virions containing a heterologous gene are introduced into a duct of a secretory gland resulting in transduction of one or more secretory gland cells. Once a secretory gland cell is transduced by the rAAV virion, the heterologous gene is expressed and the expression product is then secreted.  Exemplary examples of secretory glands are the liver, the submandibular gland, the parotid gland, and the sublingual gland. Using the methods of the invention, therapeutic levels of a protein are achieved. Methods for treating hemophilia are also disclosed.
