  • Patent number: 8645441
    Abstract: A method and system for the design and implementation of filters is presented in which the filter's transfer function can be provided with a significant insensitivity to the filter's tap coefficient values. A desensitized digital filter includes a first halfband filter and a second filter coupled in cascade between an input of the digital filter and the output of the digital filter. In embodiments, the first filter has the transfer function F(z)=K(1+z?1)(1+z?1) wherein K?0 is a scale factor. The digital filter may also interact with an up-sampler or a down-sampler. A desensitized Hilbert transformer includes an FIR filter having filter-tap coefficients whose absolute values equal the absolute values of the coefficients of an FIR filter F(z) for which the product (1+z?1)F(z) is a halfband filter coupled in cascade with a second filter.

  • Publication number: 20100121523
    Abstract: A mobile wireless local area communications network includes a pair of relatively movable nodes, such as a vehicle and a house, which are movable into and out of a defined and limited area of communications relative to the fixed node. Each node has a computer and human interface capabilities to enable transfer of data between the nodes. Each has the ability to automatically connect/disconnect the nodes when the movable node moves into/out of the area of communications. The system causes performance of a function extrinsic to the communication itself as a result of the initiation or the cessation of the communication, even after the nodes have been disconnected.

  • Publication number: 20030120695
    Abstract: An enhanced Booth-encoded adder-array multiplier where the low transition probability partial-products are generated and the adder array has been reorganized to reduce power dissipation when the Booth-encoded input has a large dynamic range. The architecture does not require extra circuits or routing overhead. Power dissipation is reduced by ordering the sequence of partial-product additions such that an increasing sequence of “transition probabilities” is encountered.

  • Publication number: 20030033413
    Abstract: A mobile wireless local area communications network includes a pair of relatively movable nodes, such as a vehicle and a house, which are movable into and out of a defined and limited area of communications relative to the fixed node. Each node has a computer and human interface capabilities to enable transfer of data between the nodes. Each has the ability to automatically connect/disconnect the nodes when the movable node moves into/out of the area of communications. The system causes performance of a function extrinsic to the communication itself as a result of the initiation or the cessation of the communication, even after the nodes have been disconnected. A music playing system enables identification of a listener to the system, who can then instruct the system to compile a personal “don't play” list of identified music pieces and types of music pieces. This prevents the identified music pieces and types of music pieces from being played when the listener is identified to the system.

  • Publication number: 20020083109
    Abstract: An adder for adding a signal at a first input (A) and a second input (B) to produce an adder output (S) is disclosed. The adder comprises a bypass input (bypass) and a logic circuit, communicatively coupled to the bypass input (bypass), the first input (A), and the second input (B), the logic circuit configured to hold at least one of the first input (A) and the second input (B) according to the bypass input (bypass).

  • Publication number: 20020013798
    Abstract: A method, apparatus, article of manufacture, and a memory structure for low power digital processing is disclosed. Tap values are modified by one or more factors to increase computational efficiency and a bias factor used to compensate for changes in the processor output response that result from the modification of the tap values.
