  • Patent number: 10128660
    Abstract: Example implementations relate to a solar panel system including solar cells and an inverter configured to receive electrical energy generated by solar cells and to convert the electrical energy to an electrical signal having an oscillation frequency. The system also include a transmit resonator coupled to the inverter and configured to resonate at the oscillation frequency. Moreover, the transmit resonator may be coupled via a wireless resonant coupling link to a receive resonator that is also configured to resonate at the oscillation frequency. Further, the system may also include a controller configured to determine for the system a mode of operation from among the following modes: (i) a common mode, (ii) a differential mode, and (iii) an inductive mode. And the controller is then configured to instruct the transmit resonator to provide via the wireless resonant coupling link electrical power according to the determined mode of operation.

  • Publication number: 20170353323
    Abstract: Connected consumer device systems are described. The consumer products associated with the systems can be powered or non-powered. The systems include one or more sensors to detect the state of the consumer product. An exemplary consumer product is designed to collect material and then be replaced once a desired amount of material is collected. The sensor is capable of detecting the existence and/or volume of material collected by the consumer product and is capable thereafter to communicate data to a hub and/or computing device. The communicated data can alert a consumer of a suggested action based on the data; for example, replace the consumer product as it has collected material. The communicated data can also trigger access to an e-commerce gateway to order more consumer products.

  • Patent number: 9259961
    Abstract: An embodiment is a method and apparatus for ultrasonic contact imaging. A thin-film transistor (TFT) array is deposited on a substrate. A receiver having a plurality of receiver elements is deposited on the TFT array to receive a received signal. A transmitter adjacent to the receiver generates a transmit signal at an ultrasonic frequency. The transmit signal is reflected from a surface to produce a reflected signal. The received signal is a superposition of the transmit signal and the reflected signal as result of interference. The received signal is representative of differences in acoustic impedances across the surface.
