Patent CA-2327772-A1 (CA)
Title: Error screening based on code and control information consistency in a communication system
Inventor: LANEMAN JERRY NICHOLAS
IPC: H04H20/00
Filed: 2000-12-07
Abstract: Improved error screening techniques for use in processing digital audio or other types of information received in a digital communication system. Control information associated with a given packet of the received information is identified and compared with a decoding requirement of the packet, in order to control the generation of an error indicator for the packet. More particularly, the error indicator may be generated in response to an inconsistency between the control information and the decoding requirement. For example, the control information may include an indication of packet length that can be compared to a number of bits required to decode the corresponding packet, with any inconsistency between the packet length indication and the number of required bits leading to the generation of an error flag for the packet. The invention is particularly well- suited for use in the processing of encoded digital audio information received in a hybrid in- band on-channel (HIBOC) digital audio broadcasting (DAB) system, but is also applicable to other types of information and other types of communication systems.

Abstract: ABSTRACT  A thin film diamond coating is formed relatively slowly with a relatively low methane concentration and is identified by its Raman spectrographic characteristics. The thin film diamond, preferably 5 to 40 microns thick, provides substantially greater corrosion and erosion resistance in a corrosive environment than other thin film diamond coatings. It is believed that such thin film diamond coating is provided with enhanced chemical resistance due to its purity and quality.

Patent CA-2333639-A1 (CA)
Inventor: SCHENONE MICHAEL A
IPC: B31B5/74
Filed: 1999-07-09
Abstract: The disclosed squaring device utilizes an upper squaring carriage (24) with compression belts (2) and pneumatically actuated squaring fingers (3). In on e embodiment, the upper squaring carriage (24) includes at least three compression belts. At least one of the compression belts, central to the oth er belts, is positioned to apply direct pressure to the glued seam after the upper panels and lower panels are aligned. As a folded box reaches the end o f the folding section and enters the squaring section, the moveable belt is raised so as not to apply pressure directly to the glued seam. The drive bel ts on either side of the seam maintain the box in compression. As the box approaches the squaring fingers, it passes a sensor that sends a signal to a  programmable logic controller. At a selected time, depending on the conveyor  belt speed, the controller actuates a pneumatic piston that drives a rack an d pinion mechanism to rotate the squaring fingers into position to intercept t he box travel. The bottom panel arrives at the fingers first, and is stopped by  the fingers, and slips on the lower conveyor belt. The upper compression bel ts continue to drive the upper panels forward until they are also stopped by th e squaring fingers, bringing the box precisely square. The squaring fingers (3 ) are thenretracted, permitting the squared box to continue through the machine. In a second embodiment of the inventive device the upper squaring carriage includes two compression belts, with squaring fingers positioned outward of the belts, with respect to the center line of the conveyor. The embodiments share the feature that the belts are controlled to exert a lower  pressure on the boxes during the squaring operation and a higher pressure on  the boxes after they are brought into square.

Patent CA-2341794-A1 (CA)
Inventor: SCHICK TROY EUGENE
IPC: B60G17/056
Filed: 2001-03-22
Abstract: An active suspension system for supporting a mass, such as a seat on a base of a vehicle, includes a hydraulic actuator coupled between the seat and the base, an pneumatic off-load device between the seat and the base, and a control system which actively controls the hydraulic actuator and which controls the off-load member. The control system actively controls the hydraulic actuator as a function of a seat position error signal.  A flow control valve controls the extension and retraction of the actuator. A proportional pressure control valve is connected between a primary pressure reducing valve and an inlet of the flow control valve. During start up, the pressure control valve prevents the supply of pressurized fluid to the flow control valve until the flow control valve is driven to its center or null position. During an electrical power failure, the solenoid operated pressure control valve is spring driven to a shut off position preventing communication of pressure to the flow control valve.
