  • Patent number: 8285246
    Abstract: An electronic implant is designed to detect at least one technical or physiological patient parameter, and has an exhaustible power source. The electronic implant also has an integrated mobile wireless antenna, a low-current mobile wireless modem with a low maximum transmission power, a low-current mobile wireless field-strength-measuring unit, and a control unit connected to the field-strength-measuring unit and to the mobile wireless modem. The control unit triggers access to a mobile wireless network as a function of the transmission power needed for data transmission by the low-current mobile wireless modem, taking into account a mobile wireless field strength value determined by the field-strength-measuring unit, and also taking into account the urgency of the data content to be transmitted. Network access only occurs when the needed transmission power does not exceed a specific maximum value for the particular urgency.

  • Patent number: 8270815
    Abstract: An online video and audio editing method and system can create edited final products by performing video and audio editing via a communication network. The system includes a server, which provides downloadable operator interface software; and a client terminal, which is connected with the server via a communication network. The client terminal downloads the operator interface software from the server to allow selection of target files, and generation of an editing result file by recording the editing information of each selected target file in a text format. The editing information is transmitted back to the server, and includes a priority order, a time to start playback, and a playback length of each selected target file. The server synthesizes all target files in accordance with the editing result file to create the edited final product.

  • Patent number: 8271085
    Abstract: An implantable medical device has an impedance or admittance determination unit, an alternating current or voltage source, a measuring unit, and an analysis unit which is connected to the alternating current or AC voltage source and the measuring unit to calculate an impedance value or an admittance value at different times. The impedance or admittance determination unit may generate measuring current having two different frequencies (preferably below 100 kHz), and the analysis unit may calculate pairs of impedance or admittance values which are chronologically assigned to one another for different frequencies of the measuring current, and calculate a value for a blood impedance or blood admittance component which is independent of the impedance of the body tissue surrounding a particular blood vessel, The analysis unit may also determine trends in this value over time as an indicator for a change of blood hematocrit value.

  • Patent number: 8235922
    Abstract: A pump supplies pressurized air to inflate compression garments, mattresses, cushions, or similar at the desired times and to desired pressures appropriate to the therapy. The garments are each identified by small steps generated in the pressure waveform during inflation, with the identifying means including a flat sheet valve in the connector chamber having vents to atmosphere and being situated along the flow path from the pump to the garment(s). As the air flows through the connection tubing and through the connector a pressure wave is generated by the valve and fed back upstream to a pressure sensor in the pump. The shape of the pressure waveform identifies a particular compression garment, the pump supplying the appropriate inflation regime upon detection of this pressure waveform.

  • Patent number: 8235815
    Abstract: A portable sensor unit for capturing motion and/or other data may be securely mounted on objects such as a user's limb, a vehicle, or other items. The sensor unit may then collect motion and/or other data from the object to which it is affixed, and may provide this data to a data logger which stores the data. The data logger may subsequently communicate the data to a gaming system which may tailor the motion characteristics of a virtual object to resemble those of the real-world object from which the motion data was captured. Thus, a user can (for example) capture motion data from a vehicle, with this data being supplied to a video gaming unit which provides a virtual vehicle having the same acceleration/deceleration, handling, and other characteristics.

  • Patent number: 8227521
    Abstract: Fluoropolymer foams are prepared by mixing fluoropolymer resin with blowing agents and additives to produce foamable compounds at temperatures below the activation temperature of the blowing agent. The compounded material is expanded at temperatures above both the softening point of the fluoropolymer resin and the activation temperature of the blowing agent. The resulting fluoropolymer foam can be fabricated into any desired shape, such as pipes, sheets, tapes, blocks and rods, using techniques such as cutting, welding, thermoforming and adhesive bonding. Alternatively the fluoropolymer compound may be expanded directly into the desired shape, for example, by expanding the compound in a mold.

  • Patent number: 8201653
    Abstract: A support for a self-balancing vehicle that allows users to operate the vehicle while standing or sitting. The support includes one or more sitting platforms connected to the vehicle. The sitting platforms are rotationally movable between standing and sitting positions. The sitting platforms are connected to the vehicle by support bars that run vertically from the sitting platforms to the body of the vehicle. Displaceable rods moveably attached to the support bars contact the underside of the sitting platforms when in the sitting position and extend past the support bars to the standing platform to activate the vehicle. A plate system interposed between where the displaceable rods extend from the support bars and the standing platform help to evenly distribute pressure exerted by the support bars on the standing platform.
