  • Patent number: 6407695
    Abstract: The invention relates to a system suitable for a remote interrogation of passive transponders using chirp signals for interrogation. The transponder preferably has an encoding unit (11), a calibrating unit (12) and a measuring unit (13) each with a plurality of parallel channels (11.1 to 11.5, 12.1 and 13.1 to 13.2). The encoding unit and the calibrating unit are preferably jointly incorporated with a common delay line (14) on the same SAW chip. The interrogation signals received in the transponder via an antenna (10) are delayed characteristically and code-specifically, in particular in the encoding and calibrating unit. Decoding in the interrogation station is preformed by discrete Fourier transformation of the response signal and subsequent evaluation of the spectrum. To correct general disturbing influences on the delay of the response signal, said signal is calibrated using a single calibrating component in the response signal.

  • Patent number: 6282559
    Abstract: A circuit module for data processing comprises several first inputs (Ix,i), several second inputs (Iy,i) and several outputs (Ii,j). First transistors (Ti,j) combine the first and second inputs. Each of the first transistors (Ti,j) is connected at its emitter or source with a first input and at its base or gate with a second input. Each second input is further connected to the base or gate and the emittor or source of a second transistor (Ti). The currents of the outputs correspond to the product of the currents through the individual inputs. By combining the outputs sum products can be calculated, especially for computing discrete probability distributions. The combination of several circuit modules allows to solve complex signal processing tasks.

  • Patent number: 5901979
    Abstract: An airbag cushion has a deployment tube connected at its inner end to a backing plate securing an inflator and at its outer end to a cushion-shaping enclosure. The periphery of the cushion-shaping enclosure is attached there about to a boundary wall which extends inward to the backing plate at a location surrounding the inner end of the deployment tube. The boundary wall defines an aspirated-air chamber surrounding the tube. As the tube and cushion-shaping enclosure are inflated, the enclosure pulls the boundary wall out of the canister creating a vacuum in the aspirated-air chamber. A one-way valve in the backing plate passes aspirated air into the aspirated-air chamber. A port connects the cushion-shaping enclosure to the aspirated-air chamber to pressurize the aspirated-air chamber at the end of inflation. The one-way valve blocks escape of the pressure.
