Title: Phasing and indicator arrangements for switchgear or the like
Inventor: MEARS GREGORY C
IPC: G01R25/00
Filed: 1998-01-26
Abstract: A phasing and indicator arrangement is provided for switchgear or the like that responds to electrical sources and provides voltage indicator functions, phasing determinations, and self-test features. Phasing provisions are responsive to two or more voltage sensors proximate respective electrical sources to provide an output that represents the phase difference, i.e. time relationship, between the electrical sources as an alternating-current voltage measurable by a voltmeter. The output is relatively independent of the voltage of the electrical sources. The indicator arrangement is operable in a test mode to test the integrity of one or more voltage indicators while clearly identifying that the indicator arrangement is in a test mode. In a preferred arrangement, the indicator arrangement in the self-test mode is powered by a photocell. Further, in the self-test mode, the indicator arrangement generates signals through each voltage sensor and over the complete voltage sensing path, the generated signals being substantially similar to the signals generated by each voltage sensor during normal operation in response to an alternating-current source. In the self-test mode, the phasing arrangement is also tested.

Title: Two-way communication system, and delay and transmission level setting methods
Inventor: MATSUNAGA YASUHIKO
IPC: H04N7/16
Filed: 1998-04-03
Abstract: A two-way communication system that can improve the shorten the system recovery time by adjusting the transmission delay or transmission level before the operation of a subscriber station and shortening the system recovery time when a link switching operation between a center station and a relay station occurs, over two-way CATV networks, passive optical star networks and the like. A center station measures the round-trip propagation delay of a signal when a subscriber station starts its operation and then sets the transmission delay of the subscriber station so as to equalize the round-trip propagation delay measured for the subscriber station to a fixed system delay. When a link switching operation occurs from a working system to a stand-by system because of the occurrence of a failure in a relay transmission line, the center station measures the round-trip propagation delay of a signal for a subscriber station after the link switching operation and then resets transmission delays of all subscriber stations connected to the relay station at a time based on the difference between the measured delay and the round-trip propagation delay of a signal to the subscriber station before the link switching operation.

Title: Enhanced batched character image processing
Inventor: SHEPARD DAVID H
IPC: G06K9/03
Filed: 1996-11-13
Abstract: Character recognition processing wherein each of a batch of documents is scanned (12) to produce corresponding scan data signals forming a rectilinear data array of binary bits at the intersections of a rectangular coordinate grid. These signals are stored and processed by a recognition algorithm to produce identity signals for recognized characters. Groups of non-recognized characters are presented simultaneously to permit rapid identification by inspection (BCIP2). The identification of recognized characters is verified at high speed by simultaneously presenting the character images as respective groups sorted to have the same recognized identities (BCIP4). High accuracy recognition is assured by including with the stored characters to be verified a number of images of purposely-incorrectly-identified characters, i.e., bogus errors. At the end of predetermined processing segments, such as one batch of documents, the results of verification are examined to determine how many bogus errors were caught. If not all the bogus errors present were caught, the operator may review the segment until all are caught. Statistical analysis of the data will provide assurance of high accuracy recognition.

Title: System and method for compensating for delays of a signal in a component of a synchronous system
Inventor: MALLETTE SYLVAIN
IPC: G06F1/10
Filed: 1998-09-30
Abstract: A system and method for increasing electrical or physical distances between components in a synchronous system controlled by a master clock signal. A multi-stage pipeline compensates for delays in transmission of signals within the system. A first stage in the pipeline generates a delay signal related to the transmission delays and it uses the delay signal for controlling receipt of the signal. In particular, it delays an internal clock signal by an amount related to the delay. Subsequent stages adjust the internal clock signal with respect to the master clock signal and the delay signal to compensate for the transmission delays. The system and method use programmable delay blocks in the pipeline to compensate for varying amounts of delay. In operation, a processor accesses a software table containing the required delay signals to adjust the internal clock, and it writes the corresponding signals to the stages of the pipeline to compensate for varying amounts of delay.
