Patent CA-2349131-A1 (CA)
Inventor: LU CHIANG-LI
IPC: A61M5/32
Filed: 2001-05-30
Abstract: A safe needle tube structure is mainly comprised of an injection tube, a connection seat, and an injection handle. A blocking-and-supporting portion is pivotally arranged in the front end of the injection tube. A connection seat is arranged inside the injection tube. And, a connection portion is pivotally arranged in the front end of the connection seat. Two ring troughs are arranged oppositely in the front end of the connection portion. A fitting-in portion is in integration and in extension arranged in the tail end of the connection seat. A gliding trough is cut and arranged inside the fitting in portion. And, an injection handle is also arranged through the interior of the gliding trough. A fitting-in block is in integration and in extension arranged in the front end of the injection handle.   If the injection handle is pulled backward, then the blocking-and-supporting portion at the front end of the injection tube will make the injection needle stay at the front end of the injection tube and the injection tube may suck in medicine for injection. After the medicine is injected, the injection handle is rotated an angle to make the ring trough of the connection portion and the ring block of the injection needle be jointed to one body. The injection handle is moved backward to tail end. The fitting block of the injection handle is separated from the gliding trough of the connection seat. The injection needle stays inside the injection tube to reach the safe injection and recycling.

Abstract: A shock absorber for a shaft. The shock absorber comprises a collar having an opening receiving the shaft. A clearance gap is defined between the collar opening and the shaft. A pin offset from the axis connects the collar to a shoulder on the shaft. A resilient o-ring arranged in the clearance gap engages the collar and the shaft. In operation, the collar and the shaft rotate in unison. However, when the collar accelerates or comes to a sudden stop, the resilient o-ring compresses to provide the shock absorption. The shock absorber may be incorporated into a rotary actuator. In a rotary actuator, the collar includes a stop tab that rotates between two stop surfaces of the actuator housing. When the stop tab strikes one of the stop surfaces, the resilient member compresses thereby absorbing and reducing impact force. Compression in the resilient member is snubbed via mechanical stops.

Abstract: The Session Initiation Protocol (SIP) is a highly flexible and extensible signalling protocol used in Internet (IP) telephony. As per the internet's nature, two peers engaged in a SIP session might not be from the same vendor, and/or might not implement the same set of capabilities and SIP extensions. For example, vendors might sometimes want to add or remove capabilities, as some implementations can be customized to fit the resources available to embedded devices, or the features required by the vendor's clients. This invention provides a flexible and easily extensible method of adding or removing the ability of understanding, accessing and creating certain SIP structures, at compile time.

Patent CA-2354461-A1 (CA)
Inventor: PAROLARI PAOLA
IPC: G01J1/10
Filed: 2001-07-27
Abstract: An optical device for providing threshold and comparison functions. The device comprises first and second SOA's having respective first and second propagation paths along which the first and second optical signals, input as signals P in1(.lambda.1) and P in2(.lambda.2), travel in first and second forward directions. A feedback path is provided using couplers to interconnect the outputs of the SOA's. As a result, a portion of the optical signals output from each SOA is supplied backwards into the output of the other SOA as feedback optical control signals P  feedback,(.lambda.1) and P feedback(.lambda.2). The feedback optical control signals modulate the gain of the forwards travelling optical signals by cross gain modulation (XGM). In contrast to prior art devices, the optical control signal is supplied backwards into the SOA's in a counter-propagating configuration. This allows much shorter feedback path lengths to be achieved in comparison to what is possible with prior art co-propagating configurations. Consequently, much higher bit rates can be achieved. The device may also be implemented in planar waveguide technology.

Abstract: A golf club shaft has a braid layer including first and second diagonal yarns. The diagonal yarns are positioned at the degrees of orientation (+ .theta. , - .theta. ) of +30° to +60° and -30° to -60° against the longitudinal axis 13 of the shaft, respectively. The braid layer has a portion that satisfies an inequality, n~ {(t-.sigma. t) /cos .theta. } ~ .eta.~ D ~ n ~ {(t+ .sigma. t) /cos .theta. }, wherein t is the average width of the diagonal yarns, .sigma.t is the standard deviation of the width of the diagonal yarns, D is the shaft diameter, and n is the number of diagonal yarns. The braid layer satisfying the inequality minimizes spaces S between the diagonal yarns. With the shaft of the present invention, the ratio of the longitudinal modulus of the shaft during a swing to the longitudinal modulus of the shaft when the head speed is zero gradually increases along with the increase in the head speed, thus suppressing shaft's deformation caused by centrifugal force during a swing and facilitating swings of the club.
