  • Patent number: 6678766
    Abstract: A synchronous communication bus for transferring data between circuit modules (2), which are connected to the communication bus, having at least one data bus (1, 3), a control bus (4) and a bus control unit (5), whereby the circuit modules send an interrupt signal to the bus control unit (5) in order to request data or, respectively, to signal readiness to send data. A memory (6) for the intermediate storage of data is provided in each circuit module (2), whereby the memories (6) are connected to the data bus (1, 3) and the bus control unit (5) is provided for clearing defined memories (6) in order to direct data from selected memories (6) into the data bus (1, 3) or, respectively, from the data bus (1, 3) into the memories (6).

  • Patent number: 6083174
    Abstract: A measuring system for measurement of patient data inside a patient's body includes a flexible foil for implantation into the patient's body. At least one sensor is arranged on the flexible foil. A first telemetry unit is also arranged on the flexible foil. The telemetry unit is provided for receiving an inductive power transmission and for transmitting data. Strip conductors electrically connect the at least one sensor element to the telemetry unit. Preferably, the at least one sensor includes a pressure sensor for sensing the patient's brain or cranial pressure. The at least one sensor may optionally include a temperature sensor the patient's brain temperature. A second telemetry unit is located outside the patient's body for receiving the data from the first telemetry unit and for transmitting the inductive power transmission to the first telemetry unit.

  • Patent number: 5831881
    Abstract: A method and circuit for forward and backward transform of a DCT and IDCT, based upon the so called "Loeffler-architecture, is disclosed. The circuit has a chip area as small as possible. The method has a small number of calculation operations and a high accuracy of calculation. The respective structures of the disclosed DCT and IDCT are as similar as possible. Based upon the high commonality of this DCT and IDCT pair, using three butterfly stages and one correction stage, the algorithms are adapted to the desired processing performance. Two of the butterfly stages are executed in a simple time multiplexed operation in common circuitry. The data is permuted after the computation of one butterfly stage and fedback via delay lines into the common circuitry for the other butterfly stage. The other stages are operated without a stepwise time multiplexed operation.

  • Patent number: 5832445
    Abstract: A method and apparatus for the decoding of digital audio data encoded in accordance with layer 1 or 2 of the MPEG format. The inverse quantization of the quantizised data samples and the resealing of the inverse quantizised data samples takes place contemporaneously with windowing of the data samples transformed into the time domain and not contemporaneously with transformation of data samples from the frequency domain into the time domain using a matrix operation. The apparatus has fixed-wire frame unpacking and filter bank units. The frame unpacking unit is used for frame synchronization of a data stream, header decoding, reading of page information, inverse quantization of quantizised subband data samples and resealing of the inverse quantizised data samples. The filter bank unit is used for transformation of rescaled data samples from the frequency domain into the time domain using a matrix operation and for windowing of the data transformed into the time domain.
