Patent CA-2404104-A1 (CA)
Inventor: GUO DIANJING
IPC: C12N9/10
Filed: 2001-03-23
Abstract: L'invention porte sur des procédés de transformation des légumineuses fourragères ou des plantes ligneuses au moyen d'un produit de recombinaison d'ADN comprenant au moins un cadre de lecture ouvert codant pour une enzyme CoA 3-O-méthyltransférase caféoyl ou une enzyme 3-O-méthyltransférase de l'acide caféique de Medicago sativa ou un fragment de celle-ci dans une orientation sens ou antisens sous un promoteur spécifique d'un tissu associé à la lignification. Ces procédés donnent lieu à la régulation progressive du gène homologue correspondant soit par inhibition de l'antisens, soit par suppression du sens, ainsi qu'une teneur réduite en lignine et une composition de lignine modifiée dans les plantes transgéniques. L'expression du transgène de 3-O-méthyltransférase CoA caféoyl produit une plus grande quantité de lignine syringyl par rapport à la lignine guaiacyl de la plante transformée, et une bien meilleure digestibilité du fourrage.

Title: Method for constructing a balanced stair
Inventor: VAN LOON MARC
IPC: E04F11/02
Filed: 2001-05-21
Abstract: For designing a balanced stair comprising steps with treads (1-15) showing front edges (26), a line of travel (22) is determined on the stair and a reference line is determined onto each step in a predetermined position with respect to the front edge (26) thereof. In contrast to the prior art methods wherein the reference lines, more particularly the front edges (26) or the risers (25) of the steps, are divided along the line of travel (22) on constant mutual distances measured on the line of travel itself, the substantially constant mutual distances (d) between the reference lines is determined according to the invention near the line of travel (22) along a measuring line (27) which is determined for each pair of adjoining reference lines so as to form a substantially constant angle (.alpha.) with at least one of the adjoining reference lines thereof. In this way, a stair which is easier to walk on and which automatically shows a more regular nosing line at the outer string (21) is obtained.
Patent CA-2414791-A1 (CA)
Inventor: BRONDIJK ROBERT ALBERTUS
IPC: G11B27/30
Filed: 2002-04-18
Abstract: A method and device for recording information blocks on a record carrier is described. The device has control means for recording and retrieving position data indicative of the position of the recorded information blocks. The control means include a mapping unit for determining in which region the information block is recorded and a detection unit. The region is one of a number of consecutive regions constituting the recordable area. The mapping unit records a random signal unit in a unit location in a mapping area. The unit location indicates said region, and the unit length of the random signal unit is smaller then the length of said information block. The detection unit detects the presence of the recorded random signal units in said mapping area and so determines if a region contains at least one information block. The highest written address is found by detecting the highest written unit location in the mapping area, and subsequently searching said region for the presence of recorded marks.
Patent CA-2415977-A1 (CA)
Title: Generation and use of masks in mpeg video encoding to indicate non-zero entries in transformed macroblocks
Inventor: KLIVINGTON JASON
IPC: H04N7/50
Filed: 2003-01-06
Abstract: During Motion Picture Experts Group (MPEG) video encoding a two-dimensional discrete cosine transform (DCT) is performed on data representing an original image. The resulting coefficients are then quantized, which typically results in many zero coefficients. Because of the nature of most video data, most higher-order coefficients are typically zero and the lower-order coefficients (i.e., those grouped towards the upper left of the matrix) are more likely to be non-zero.  To reduce the lengths of runs among the lower-order coefficients, the coefficients can be encoded in a zig-zag pattern. In one embodiment, the zig-zag pattern is maintained and one or more masks are generated based on the output of the quantization phase. The one or more masks are used to identify the coefficients within the matrix that are non-zero. This reduces the number of accesses to memory required to encode the non-zero coefficients and runs of zero coefficients.

Title: Power cutback configuration of digital subscriber line transceivers using public switched telephone network signaling
Inventor: HANSEN CARL C
IPC: H04B3/04
Filed: 2001-11-19
Abstract: The invention provides a technique for power cutback of DSL transceivers (e.g., modems) using public switched telephone network (PSTN) signaling. For example, one or more dual-tone/multiple frequency (DTMF) signals generated by a touch-tone telephone, or other device, can cause a DSL transceiver to reduce the power of upstream data communications. A user of a DSL modem can cause th emodem to transmit upstream data while listening to the microphone of a telephone coupled to the same twisted-pair line. Data transmission power can be adjusted by use of one or more buttons on the telephone. The DSL  transceiver, in response to one or more predeteremined DTMF signals, can adjust transmission power. Thus, the poer cutback of the DSL transceiver can be controlled using PSTN signaling.

The four-bar mechanical linkage includes two handles, a link and a rotating cam-like piston. The rotating cam-like piston, upon movement of the handles relative to one another, rotates to correspondingly translate the drive rod assembly to impart movement to the jaw members between the first and second positions.

Title: Valve for bathtub design with therapeutical treatment devices
Inventor: MARTIN LOUIS
IPC: A61H33/02
Filed: 2000-04-18
Abstract: A hydro massaging tub is used for massage treatment wherein the treatment is performed by ozone-mixed warm air or water jets distributed adjacent the bottom wall of the tub all about its circumference.      Ozone generated by an ozone generator is injected in an air distribution duct to sterilize the air distribution system and help clean the skin of the bather's body. The oxygen liberated in the water and the air improves the quantity of oxygen in the bather's environment so that oxygen intake through the skin and lungs is facilitated.   A mobile air jet and section control of the air jets enable the bather to massage selective body areas with adjustable intensity of sections of the massage to achieve a desired effect. In one embodiment, orientable valves are mounted in the air jet holes for adjusting the orientation of the air jets. In another embodiment, optical fibers or light emitting diodes are provided to emit light frequencies in the water turbulence for physiological and therapeutic effects. The air distribution system may be made from material treated with antibacterial agents to maintain a clean condition and ensure the bather's health.
