  • Patent number: 6883381
    Abstract: An acceleration sensor includes a deflectable pressure measuring diaphragm and a counter-structure, which is deflectable as against the pressure measuring diaphragm. The acceleration sensor includes a detection means for detecting a deflection of the pressure measuring diaphragm as against the counter-structure. Further, a test mass is connected to the pressure measuring diaphragm or the counter-structure in order to be deflected from an idle position depending on an acceleration applied. The deflection of the test mass results in a change of the distance between the pressure measuring diaphragm and the counter-structure, which is detectable by the detection means.

  • Patent number: 6885256
    Abstract: An input circuit for an HF-transmitting component 1 of a battery-operated device for the transmission of a data signal aims to reduce the power consumption. For that purpose the fundamental frequency of a reference oscillator 5 is modulated with the digital data signal, the data rate being greater than 20 kchip/s. For smoothing of the modulated reference signal an amplitude limiter 11 and a band pass filter 15 are connected between the reference oscillator 5 and the HF-transmitting component 1.

  • Patent number: 6828605
    Abstract: A field-effect-controllable semiconductor component has at least one source zone and at least one drain zone of a first conductivity type, and at least one body zone of a second conductivity type. The body zone is provided between the source zone and the drain zone. In each case at least a first and a second region of the second conductivity type are provided in a channel zone. The first region has a first doping concentration and the second region has a second doping concentration, which is lower than the first doping concentration. The combination of the two regions produces a semiconductor component threshold voltage greater than zero and the on resistance is lower than that merely due to a channel zone doped with the first or second doping concentration.

  • Patent number: 6824536
    Abstract: Shaped tampons having varying volumes are provided. A tampon which is formed into a self-sustaining shape has an outer surface, which is substantially serpentine. The tampon also has continually changing volume. The shaped tampons may also have varying average fiber density regions. The shaped tampons may be wrapped in tightly conforming wrappers which optionally aid in maintaining the self-sustaining shape prior to use. Optionally, the shaped tampons may utilize tampon applicators which enable a user to visually see the shape of the tampon prior to use.

  • Publication number: 20040236173
    Abstract: An extracardiac pumping for supplementing the circulation of blood, including the cardiac output, in a patient without any component thereof being connected to the patient's heart, and methods of using same. One embodiment of the intravascular extracardiac system comprises a pump with inflow and outflow conduits that are sized and configured to be implantable intravascularly through a non-primary vessel, whereby it may positioned where desired within the patient's vasculature. The system comprises a subcardiac pump that may be driven directly or electromagnetically from within or without the patient. The pump is configured to be operated continuously or in a pulsatile fashion, synchronous with the patient's heart, thereby potentially reducing the afterload of the heart.

  • Patent number: 6803609
    Abstract: A bipolar high-voltage power component, in particular an IGBT, includes a semiconductor body on which at least two mutually spaced apart electrodes are provided, between which a drift path is formed in a semiconductor region of a first conduction type. Floating zones of a second conduction type, opposite the first conduction type, are provided in the semiconductor region. When the power component is switched on or switched off, the floating zones respectively emit charge carriers of the second conduction type into the semiconductor region or take up the charge carriers from the semiconductor region. The floating zones are connected, through a respective MOS transistor with a channel of the second conduction type or a bipolar transistor with a base of the first conduction type, to active regions of the power component which are connected to the two electrodes.

  • Patent number: 6765262
    Abstract: The present invention relates to a high-voltage semiconductor component having a semiconductor substrate of a first conduction type on which a semiconductor layer is provided as a drift path that takes up the reverse voltage of the semiconductor component. The semiconductor layer is either of the first conduction type or of a second conduction type that is opposite the first conduction type. The semiconductor layer is more weakly doped than the semiconductor substrate.

  • Publication number: 20040138519
    Abstract: A multilumen catheter that maximizes the blood flow into and out of the patient's vasculature while also providing for passive and/or active perfusion of tissue downstream of where the catheter resides in the vasculature. The inventive catheter comprises a proximal end, a first distal and a second distal end. Lumens extending from the proximal end to each of these distal ends provide for blood circulation within one or between two blood vessels. At least one aperture in one of the lumens positioned near the proximal end provides for active perfusion of blood to the patient's vasculature downstream of where the aperture resides in the vasculature when the catheter is inserted into the patient for treatment. The inventive catheter may comprise a third lumen positioned entirely within the patient's vasculature, providing passive perfusion of blood to the patient's vasculature downstream of where the third lumen resides in the vasculature when the catheter is inserted into the patient for treatment.
