    摘要： A data processing system is disclosed including a decoder circuit, syndrome calculation circuit and hash calculation circuit. The decoder circuit is operable to apply a decoding algorithm to a decoder input based on a first portion of a composite matrix to yield a codeword. The syndrome calculation circuit is operable to calculate a syndrome based on the codeword and on the first portion of the composite matrix. The hash calculation circuit is operable to calculate a hash based on a second portion of the composite matrix. The decoder circuit is also operable to correct the codeword on the hash when the syndrome indicates that the codeword based on the first portion of the composite matrix is correct but a second test indicates that the codeword is miscorrected.

    摘要： An optical network including a plurality of gateway nodes interconnected with a plurality of intermediate nodes with segments of fiber. The network includes a plurality of devices, such as reconfigurable optical add drop multiplexors, optimally placed at various nodes throughout the network. The device placement is optimized with an integer linear programming analysis considering span definition such that any given span involves some number of segments not exceeding a number of segments that would require wavelength regeneration, cost of placement of a device at a given node, cost of wavelength regeneration, and various parameters and constraints.

    摘要： A sensing system for a computer input device. The sensing system comprises an actuator to attach to a key top or button. The actuator is moveable along an axis or hinged. The sensing system further comprises a biasing element to exert a biasing force on the actuator directed along the axis. The sensing system further comprises an actuator motion sensor associated with the actuator. The actuator motion sensor comprises a passive resonant circuit configured to be moved by the actuator and having a resonant frequency, an active resonant circuit configured to excite the passive resonant circuit at the resonant frequency, a sensor driver to drive the active resonant circuit with an RF drive signal at the resonant frequency, and a detector to detect a level of RF signal from a driven actuator motion sensor for sensing a position and/or velocity of the actuator.

    摘要： A sensing system and method for detecting a position and/or velocity of keys on a keyboard. The keyboard is provided with a set of sensors, each sensor comprising a passive resonant circuit for mounting on a moving part of a key and an active resonant circuit for mounting in a reference position. One or more coils of the active resonant circuits have windings in opposite senses to reduce interference between sensors of adjacent keys. The passive resonant circuit has a resonant frequency and the active resonant circuit excites the passive resonant circuit at the resonant frequency. Each sensor has a detector to detect variations of a resonant signal in the active resonant circuit with relative position of the active and passive resonant circuits to detect a position and/or velocity of the key.

    摘要： A sensing system and method for periodically compensating a response of a keyboard. Each key of the keyboard is provided with a key sensor, with each key sensor comprising a passive resonant circuit, an active resonant circuit and a detector. A detected initial output signal, O t0 , of an initial key sensor, K 0 , is retrieved from storage. The detected initial output signal O t0 corresponds to an output signal of the initial key sensor K 0 detected at a first time, t 0 at which an active resonant circuit of the initial key sensor K 0 is driven at a frequency below a resonant frequency of the active resonant circuit of the initial key sensor K 0 . Periodically thereafter, a later output signal, O t1 , is detected, and an adjustment value is calculated. The adjustment value corresponds to a difference between the initial output signal O t0 and the later output signal O t1 . The response of the keyboard may then be compensated using the adjustment value.
