Title: Method and apparatus for decoding bar code symbols using ratio analysis of module size
Inventor: LEI MING
IPC: G06K7/14
Filed: 1997-10-01
Abstract: An improved method and apparatus for decoding bar code sym-bols using an analysis of the ratios of the module size for the bars and spaces of the bar code. The invention is applicable to any bar code having one or more nominal widths in the bars and spaces, and is par-ticularly useful in bar codes having multiples widths in the specification for the bar code and in situations where the bar code signal has a low signal-to-noise ratio, or is degraded because of a damaged, smudged, or dirty bar code, or where the bar code is read at less than the opti-mum angle. The invention identifies misdecoded characters and uses adaptive techniques to decode characters previously non-decodable or misdecoded by standard methods, thereby improving the decode rate as compared to prior techniques. The decoding rate is improved with-out having to re-scan the bar code for a new signal, thereby making the invention particularly useful for high-speed or one-pass decoding operations.

Patent CA-2271240-A1 (CA)
Title: Electrical switching apparatus with modular operating mechanism for mounting and controlling large compression close spring
Inventor: WEHRLI HANK ANTHONY III
IPC: H01H3/30
Filed: 1999-05-06
Abstract: Electrical switching apparatus such as a power circuit breaker, network protector or switch has a self-supporting operating mechanism module including a cage formed by a pair of side plates rigidly clamped in spaced relation by spacers. The cage supports all of the operating mechanism components including a helical compression close spring mounted fully between the side plates and coupled to a cam member through a rocker in a manner which maintains the forces longitudinal to the spring. The cam member has a charging cam with a charge profile for compressing the close spring and a close profile through which the spring drives the cam member to effect a controlled release of stored energy to close the contacts of the apparatus. A close prop, spring biased to an unlatched position, is latched to secure the close spring in the charged state by a latch assembly reset by a reset lever separate from the close prop which in turn is reset by rotation of the cam member during charging. An interlock prevents release of the close spring when the contacts are cloned or the trip release is actuated. An indicator actuated by a driver pivoted against the cam shaft snaps from a DISCHARGED to a CHARGED indication as the close spring becomes fully charged and the driver drops into a notch created by a flat on the cam shaft. A snap action open/closed indicator for the switch contacts is also provided. Both indicators are pivotally mounted in a face plate pinned to the side plates and are connected to the operating mechanism by wireforms. The close and open push buttons snap out to a common shaft and have actuating fingers which trigger releases in the operating mechanism. The close rotating shafts are journaled solely in confronting apertures in the side plates. The cam shaft is captured between bushings seated in non-circular openings in the side plates thereby eliminating the need for any fasteners. Likewise, other parts mounted between the side plates and joined by pins having enlarged heads retained by the side plates do not need retainers. Various shafts extending between the side plates have reduced diameter ends of progressive lengths for successive insertion in one side plate to aid in assembly of the operating mechanism.
