Title: Automatic equalization of video signals
Inventor: AHERN STEPHEN M
IPC: H04N7/10
Filed: 2003-02-19
Granted: 2010-10-26
Abstract: This invention is a video compensation system for analog video transmission. The compensation system is employed in an analog video switching circuit such that each time a conductive path is switched, the system automatically tests the new switch path for a new compensation value. The compensation value is determined by measuring the response of the new, path to a set of tones that are applied to the conductive path. the response to which is measured against a table of responses previously recorded. The measured response are compared to the recorded responses to determine an appropriate compensation control voltage (V1, Vm, Vh), which is applied to an equalizer system (50-54). In an alternative embodiment, skew compensations also provided between red, green and blue twisted pair lines in the cables by performing comparative analysis between corresponding pairs of red, green and blue twisted pair lines in the cable by performing comparative analysis between corresponding red, green and blue signals.

Le procédé concerne le traitement dun matériau de bois prétraité en utilisant une ou plusieurs étapes de raffinage à consistance élevée pour produire une première pâte, appliquant éventuellement un agent de chélation à la première pâte pendant le raffinage à consistance élevée pour produire une pâte stabilisée et le traitement de la première pâte ou la pâte stabilisée avec une liqueur de peroxyde alcalin pour produire une pâte traitée. La pâte traitée est ensuite traitée par une ou plusieurs étapes de raffinage à consistance basse. En variante, la première pâte ou la pâte stabilisée peut être divisée en un flux principal ou secondaire. Le flux principal est traité avec une liqueur de peroxyde alcalin pour produire une pâte traitée. Le flux secondaire est traité en utilisant une étape de raffinage à consistante élevée secondaire pour produire une pâte partiellement raffinée, et en retirant la latence de la pâte partiellement raffinée et la pâte traitée est retirée dans un emplacement commun. La pâte traitée et la pâte partiellement traitée sont traitées par une ou plus dune seconde étape de raffinage à consistance basse pour produire une pâte finale.

Title: Zeroing-out llrs using demod-bitmap to improve performance of modem decoder
Inventor: CHALLA RAGHU N
IPC: H04L25/06
Filed: 2009-03-25
Granted: 2014-10-07
Abstract: A demodulation mask bitmap includes binary mask values. Each mask value corresponds to an input resource element to a demodulator. For each mask value of a first state, a demodulation engine of the demodulator is not clocked and the demodulator outputs a zero-valued resource element. For each mask value of a second state, the demodulation engine is clocked, the input resource element is demodulated, and the demodulator outputs a demodulated resource element. A demodulation mask bitmap is designed to mask pilot resource elements and corrupted resource elements. Power is conserved by not clocking the demodulation engine for corrupted and pilot resource elements. Subsequent LLR generation and decode operations are simplified. Decoder performance is improved because the decoder does not decode LLR values derived from corrupted resource elements and/or resource elements not relevant to the reconstruction of a communicated message.
