  • Patent number: 6650638
    Abstract: The frame of data that is decoded is one of a set of frames that represent a packet of information words, and that additionally represent coded control words preceding and following the packet. The frames each include a master transition and a payload field. The payload field either is composed exclusively of ones of the information words, or includes a TYPE word that defines the structure of the payload field. The master transition is in a first state when the payload field is composed exclusively of ones of the information words, and is otherwise in a second state. In the method, a determination is made of whether the master transition is in the first state. When the master transition is in the first state, the payload field is adopted as a block of received data. When the master transition is not in the first state, the TYPE word is extracted from the payload field, the payload field is expanded in response to the TYPE word, and the payload field, after expansion, is adopted as a block of received data.

  • Publication number: 20030123591
    Abstract: The present invention provides a multi-phase sampling system in which each sampler samples a transition and data of an incoming data signal. By enabling each sampler to sample a transition in addition to data of the incoming data signal, phase errors associated with each of the samplers can be determined. The phase error determinations provide valuable information that can be used 1) to correct the phase errors of the system sampling the incoming data signal, 2) to correct the phase errors of a multi-phase system that is transmitting the incoming data signal, and/or 3) to correct the phase errors of both a multi-phase system that is sampling an incoming data signal and of a multi-phase system that is transmitting the data signal.

  • Publication number: 20030110434
    Abstract: A communications system and method are disclosed. A transmitter includes a scrambler for scrambling original data, an ECC encoder for converting scrambled data into ECC data, and a serializer for converting the ECC data into a serial stream. A receiver includes a frame recoverer for converting the serial data into frame data, an ECC decoder from converting the frame data into ECC data and error indications, and a descrambler for restoring the original data. By using the results of the ECC decoding to convert the serial data into frame data, line decoding is unnecessary, thereby reducing channel usage.

  • Patent number: 6501404
    Abstract: A method compares an input value of the input signal stream with an output value of an integration function of a previous binary value to generate a new binary value based upon the comparison. The method then stores a plurality of successive binary values from the comparing step, and simulates an integration function for a plurality of possible bit sequences of the plurality of successive binary values. Finally, the method determines which sequence results in the smallest error between the input signal stream and the output value of the integration function, and uses the most significant bit of the determined sequence to adjust the integration function. A corresponding apparatus is also provided.

  • Publication number: 20020129307
    Abstract: Self testing of a data communication system that includes a presettable scrambler and a complementary presettable descrambler is performed by presetting the presettable scrambler to a preset state. A seed payload field is scrambled using the presettable scrambler to generate fields of a test sequence. The fields of the test sequence are transmitted and corresponding received test sequence fields are received. The received test sequence fields are descrambled using the presettable descrambler to generate respective recovered test sequence fields. Differences between the recovered test sequence fields and the seed payload field are then detected as errors. A data communication system having a built-in self-test facility comprises a seed payload field source, a presettable scrambler, a presettable descrambler and an error detector. The presettable scrambler includes an input connected to the seed payload field source and an output coupled to a data transmission medium.

  • Patent number: 6359662
    Abstract: A method and system for compensating for defects in a multi-light valve display allows for the compensation of defective pixels in a display. By sequentially illuminating all light valves in a multi-light valve system with all colors, or wavelengths, available in the display, each light valve modulates the full gamut of colors available in the system. In this manner, the remaining light valves can compensate for a defective pixel in one of the light valves. The invention also includes an active compensation feature, whereby defective pixels in the display are identified and are compensated for by an associated display driver.

  • Patent number: 6249269
    Abstract: The analog drive circuit drives a pixel electrode in response to an analog sample derived from a video signal. The analog drive circuit comprises a sample selection section and a drive signal generator. The sample selection section receives and temporarily stores the analog sample during a sample load period. The drive signal generator generates a drive signal and applies the drive signal to the pixel electrode during a display period that follows the sample load period. The drive signal is composed of a sequence of a first temporal portion and a second temporal portion. The first temporal portion has a time duration substantially proportional to the analog sample temporarily stored in the sample selection section. The second temporal portion is the temporal complement of the first temporal portion.

  • Patent number: 6157317
    Abstract: A stop and control box houses the standard phone pager (a COTS APPLICATION--meaning commercial off the shelf) as a stimulating and communication device in either a secured and/or concealed mechanical lockup or in any protected area that employs any means to limit access. This protected area would also house control circuitry and could house monitoring circuitry to interface with and record the host machine's functions and finally record the operator and occupant's activities. The stop and control box accomplishes its remote capabilities in a number of ways from actually being wired directly to the pagers circuitry to merely sensing or reading the pager functions and numerical messages.
