  • Patent number: 11745023
    Abstract: Improved devices, circuits and methods of operation in implantable stimulus systems. An implantable defibrillator may comprise a charging circuit using a transformer to store and build up energy on an HV capacitor or capacitor stack, with the HV capacitor in turn coupled to an H-bridge output circuit having low and high sides for issuing therapy. In the output current path, a current controlling circuitry is placed between the H-bridge and ground, allowing the greater flexibility in the selection of switching devices, and drivers for such devices, in the H-bridge circuit and/or enabling circuits between the H-bridge and the HV capacitor or other therapy circuit.

  • Patent number: 8483590
    Abstract: According to aspects of the embodiments, there is provided an apparatus and method to maintain a clean and effective external heat roll surface in a printing system. The disclosed embodiment's uses a cleaning roller in contact with the external heat rollers designed to dislodge and displace contamination products that would otherwise accumulate on and in the external heat roller rough surface. The cleaning roller rotates concurrently with the heating roller so that the cleaning media cleans the roller from a picking action as opposed to a wiping motion. This provides maximum cleaning action with the undesirable wear and tear of the bristles that would occur with the conventional method of a wiping motion.

  • Patent number: 8276468
    Abstract: According to aspects of the embodiments, an apparatus and method is proposed to detect nip width by use of at least one piezoelectric (PZT) crystal embedded into a roll at both the inboard and outboard ends. A piezoelectric (PZT) crystal generates a charge when subjected to a load and when the load is released. The PZT generate signal is channeled to the ends of the roller such as with a brush contact to be processed and used within machine control. The duration measure from application and released of the load is indicative of the dwell time and the amplitude PZT generate signal is a function of the pressure. The time and amplitude of the PZT signal can be calibrated to correlate directly to nip width or pressure and tracked in machine control.

  • Patent number: 7799752
    Abstract: A composition such as a water-based consumer product comprises material (e.g. perfume) encapsulated within shell capsules, each capsule comprising an encapsulating wall having an inner surface and an outer surface, with a coating on the inner surface and/or outer surface of the shell wall, the composition further comprising surfactant and/or solvent. The coating can improve the barrier properties of the shell and can enhance retention of the encapsulated materials within the shell.
