Title: Passenger-side airbag module darted end caps
Inventor: DAVIS TERRY R
IPC: B60R21/20
Filed: 1995-09-22
Abstract: The screws which are normally employed to attach the end plates to the trough-shaped main body of a passenger-side airbag module reaction canister are replaced by impact-driven darts. The darts are made of material harder than that of the main body and include surface irregularities which deform the material of the main body and improve the frictional engagement.

Title: Lightweight metal truss and frame system
Inventor: BASS KENNETH R
IPC: E04C3/32
Filed: 1994-03-30
Abstract: The lightweight metal construction system begins with a beam (2) formed from a single piece of cold formed sheet steel or other sheet metal which is bent lengthwise along four lines to form a triangular cross section with two wings (4, 6), side-by-side, extending from its apex. The ends of the beams may be modified to form joints which are used to connect two beams together or to connect the beam to another construction material. Brackets (20) formed from strips of sheet steel or other metal are bent to conform to outer surfaces of the beams or other construction materials are used to attach the beams to other beams or other construction materials. Fasteners (40) are used to firmly attach the joints and brackets to the beams and construction materials.
Patent CA-2162887-A1 (CA)
Inventor: EDWARDS STUART D
IPC: A61B10/00
Filed: 1994-05-13
Abstract: A method and an apparatus (14) is disclosed for deliv-ering controlled heat to perform ablation to treat the benign prosthetic hypertrophy or hyperplasia (BPH). According to the method and the apparatus (14), the energy is transferred directly into the tissue mass (6) which is to be treated in such a manner as to provide tissue ablation without damage to surrounding tissues. Automatic shutoff occurs when any one of a number of surrounding areas to include the urethra (2) or surrounding mass or the adjacent organs (6) exceed pre-determined safe temperature limits. The constant application of the radio frequency energy over a maintained determined time provides a safe procedure which avoids electro-surgical and other invasive operations while providing fast relief to BPH with a short recovery time. The procedure may be accomplished in a doctor's office without the need for hos-pitalization or surgery.
Patent CA-2162947-A1 (CA)
Inventor: CANTER STANLEY
IPC: H02M3/157
Filed: 1995-11-15
Abstract: A multi-slice power converter  (10)  employs  a  digital circuit  (22)  to  generate  phase-delayed  pulse  width modulated (PWM) signals, which results in the duty cycle of the PWM signals having only a certain number of possible values. The quantization of the duty cycle is shown to result in two types of instabilities which are unique to power converters having a digital control loop, in addition to the conventional analog-type of instabilities.  This invention  provides  novel  methods  and  apparatus  for stabilizing the digital control loop of the power converter through the use of a periodic dither signal having a frequency that is less than the PWM frequency and greater than a bandwidth frequency of the converter. The dither signal functions to effectively increase the number of possible duty cycles by a factor given by the ratio of the dither frequency to the bandwidth frequency.

Title: Microvessel cell isolation method and apparatus
Inventor: MYERS KEITH
IPC: A61F2/06
Filed: 1994-07-01
Abstract: A processing vessel (12) for isolating microvessel endothelial cells from liposuctioned fat tissues includes a fat-receiving basket (54) defined by polyester screen material. Fat tissue removed from a patient by liposuction is received into the basket (54) and is rinsed and digested with an enzymatic solution. The freed microvessel endothelial cells from the fat tissues are separated from the fat cells, and from blood cells and other materials which may be present in the basket by centrifuging. A bottom chamber (62) of the processing vessel (12) is configured to define a "pellet" of isolated endothelial cells which may be removed from the processing vessel (12) for deposition on the inner lumenal surface of a synthetic graft which the fat-donor patient is to receive.

Patent CA-2170696-A1 (CA)
Inventor: BALDWIN JOHN R
IPC: G01R31/06
Filed: 1996-02-29
Abstract: A step down transformer power supply with short circuit protection which uses a minimal size transformer, as opposed to an energy limiting transformer. The transformer is mounted directly on a PC board without additional mounting hardware, and has a fuse in its secondary winding, which is required to pass a UL short circuit test, and is normally nonreplaceable. A low cost circuit limits the current output of the transformer such that the fuse is not blown, even under a shorted output condition, which would normally require replacement of the transformer. A rectifier circuit is coupled across the secondary winding of the step down transformer, and is coupled to a first terminal of a three terminal power regulator circuit which supplies a regulated stepped down voltage through a second terminal connected to a load. The third terminal thereof comprises a current/voltage limiting control terminal. A resistor is coupled in series with the load to sense the output current through the load, and is connected to the base of a transistor having an emitter, collector, and base. The collector and emitter of the transistor are coupled in series with the control terminal of the power regulator circuit, such that as the output current increases above a threshold indicative of a short, the output current of the power regulator is limited to prevent the slow-blow fuse from being blown.
