Patent CA-2202959-A1 (CA)
Title: Bit-serial digital compressor
Inventor: OLIVER JOHN PAUL
IPC: H03G11/00
Filed: 1997-04-17
Abstract: A bit-serial compressor (106) has a pre-divider circuit (208) receiving input serial data and generating a partial numerator. Divider circuit (210) divides the partial numerator by a denominator and generates a partial remainder that is fed back to the pre-divider circuit (208). Divider circuit (210) also generates serial data that is sent to an absolute value circuit (216)and then to a bit-serial filter (218). Bit-serial filter (218) generates an average signal from the serial data. A comparator circuit (224) compares the average signal to a threshold signal and generates the greater of the average signal or the threshold signal for use as a denominator in a next division cycle. The divider circuit includes an overflow control circuit (618) which detects overflow from the carryout bit of the partial remainder operation at the beginning of a division cycle and the sign bit of the numerator. If overflow is detected, the output is clipped according to whether the numerator is positive or negative.
Patent CA-2203425-A1 (CA)
Inventor: JEONG JAE-HO
IPC: B60R21/217
Filed: 1996-08-29
Abstract: A hybrid air bag system has a simple internal structure and can be manufactured at a low cost. The hybrid inflator is positioned within a first container (210) which has a rupturable cover and a bottom plate. The hybrid inflator has a second container (214) defining a first chamber (302) filled with a quantity of compressed gas, and then sealed. A pyrotechnic heater (350) contains a pyrotechnic charge (366) and squib (364) therein and generates high temperature combustion products by burning a pyrotechnic charge contained within a second chamber, a booster charge (384), and a gas generating material (386) contained within a third chamber. The combustion products push upwardly against a lower end surface of an operation pin (420) elastically supported by a plate spring (412) and slidably and vertically positioned within a fourth chamber (410). The operation pin ruptures a burst disk (330) sealing the first chamber. Consequently, the compressed gas in the second container (214) and the combustion products are united and injected into an inflatable air bag to inflate the air bag. Thus, a passenger in a motor vehicle can be protected from colliding with a structural part of the motor vehicle.

Patent CA-2206330-A1 (CA)
Title: Imaging apparatus and method and liquid toner therefor
Inventor: ALMOG YAACOV
IPC: G03G9/12
Filed: 1994-12-29
Abstract: Scuff resistance, abrasion resistance and peel resistance of a wide class of liquid toners may be improved by the addition of a minor amount of an additional material which, at the fusing temperature used for the toner, has a much lower viscosity, preferably several orders of magnitude lower, than the viscosity of the toner particles at the fusing temperature and which forms a separate phase from the toner particles when solidified. It is believed that such material, during the fusing process, migrates to the outer surface of the image. During cooling of the image after it is fused, the additional material forms a substantially separate phase resulting in a hard slippery coating of the additional material which protects the image from abrasion.
