  • Patent number: 9449308
    Abstract: Embodiments provide visual programming constructs including icons representing conditions and actions for processing incoming data streams. A user selects icons corresponding to at least one of the conditions and at least one of the actions to define a rule. The selected condition relates to at least one element possibly present in the incoming data stream. Without compilation of the rule, at least one incoming data stream is analyzed based on the condition to detect a presence of the element within the incoming data stream. The action is performed based on the analysis. In some embodiments, formatting of the incoming data streams is altered according to the conditions and actions to personalize the incoming data stream.

  • Patent number: 9368274
    Abstract: A wireless power transfer system including a driver coil array, a hexagonally-packed transmitter mat, a receiver coil, and a load coil for powering a medical implant. The magnetically coupled resonance between two isolated parts is established by an array of primary coils and a single small secondary coil to create a transcutaneous power link for implanted devices as moving targets. The primary isolated part includes a driver coil array magnetically coupled to a mat of hexagonally packed primary coils. Power is injected by the driver coils into the transmitter coils in the transmitter mat to maintain resonance in the presence of losses and power drawn by the receiver coil from the magnetic field. The implanted secondary isolated part includes a receiver coil magnetically coupled to a load coil. A rectification/filter system is connected to the load coil supplying DC power to the electronic circuits of the implant.

  • Patent number: 8781479
    Abstract: The described implementations relate to automatic network selection in relation to wireless mobile devices. One method can be applied to a mobile device that has both Wi-Fi and cellular capabilities. The method can attempt to identify Wi-Fi network availability for the mobile device. This method also evaluates whether to configure the mobile device to accomplish data communication over an identified Wi-Fi network or a cellular network.

  • Publication number: 20110267620
    Abstract: A sensor to simultaneously detect light and acoustic waves is presented. The sensor includes one or more optical fibers and a diaphragm disposed near one end of at least one of the one or more optical fibers. The diaphragm is configured to vibrate upon incidence of acoustic waves from an arc flash and reflect a light beam into at least the one of the one or more of the optical fibers. A semi-transparent region is disposed around the one or more optical fibers to diffuse light originating from the arc flash into at least one of the one or more optical fibers.

  • Patent number: 7822578
    Abstract: Predictive maintenance systems and methods are described. A method includes measuring environmental conditions using a plurality of sensors within the IED, processing the environmental measurements to determine long-term exposure factors representing historical operating conditions of the IED, applying a reliability model to the long-term exposure factors, determining a numerical measure of IED life based on the long-term exposure factors and the reliability model, comparing the numerical measure of IED life to preselected boundary values, and signaling if the numerical measure of IED life is outside of the preselected boundary values.
