| 20080237003 | Inertial switch using fully released and enclosed conductive contact bridge - A micro-electromechanical system (MEMS) switch comprises a trench formed in a substrate. A free moving conductive mass may be formed within the cavity. When the switch is moved or otherwise acted upon my an inertial force to conductive mass makes contact with a pair of electrodes partially covering the trench thus turning the switch on. | 10-02-2008 |
| 20080238680 | Temporary non-responsive state for RFID tags - A radio frequency identification (RFID) tag may have a non-responsive mode, triggered by a command from an RFID reader, that temporarily prevents the RFID tag from responding to a query from any RFID reader for a period of time. In some embodiments this non-responsive mode may automatically end after a certain period of time without further action by the RFID reader. In other embodiments this non-responsive mode may end when directed to by another command addressed specifically to the RFID tag. | 10-02-2008 |
| 20090134952 | POWER HARVESTING SIGNAL LINE TERMINATION - In various embodiments of the invention, a power-harvesting termination circuit may be used to 1) match the impedance of a signal line being terminated, and 2) recover a portion of electrical power from a signal on the signal line and provide the recovered power as an electrical voltage to be used to power other circuits. The power may be harvested at either the receiving device or at the transmitting device. | 05-28-2009 |
| 20090167495 | RADIO FREQUENCY IDENTIFICATION TAGS ADAPTED FOR LOCALIZATION AND STATE INDICATION - An embodiment of the present invention provides a radio frequency identification (RFID) tag, comprising at least one light emitting diode (LED) that is controlled by the RFID's logic and powered by the RFID's power harvesting circuit, wherein the RFID tag is capable of being interrogated by an RFID reader and reporting its unique identification number by RF backscatter and/or controlling the illumination state of the at least one LED. | 07-02-2009 |
| 20090243813 | WIRELESS PROGRAMMING OF NON-VOLATILE MEMORY WITH NEAR-FIELD UHF COUPLING - Near-Field UHF wireless coupling may be used to write data into a non-volatile memory in a device, thus allowing for changes to be made to the device after that product has been manufactured. Energy from the received wireless signal may be used to power sufficient circuitry in the device so that the programming does not require an on-board power source such as a battery. In many cases, the device may be programmed after it has been packaged for shipment/sale, without removing the device from the package. In some embodiments, a multi-segment antenna may be used to program multiple such devices at the same time by the same Near-Field UHF signal. | 10-01-2009 |
| 20100045114 | ADAPTIVE WIRELESS POWER TRANSFER APPARATUS AND METHOD THEREOF - In accordance with various aspects of the disclosure, a method and apparatus is disclosed that includes feature of coupling a resonator of a transmitter and a resonator of a receiver together by a common inductance of the transmitter and the receiver; and adjusting environmental parameters or system parameters or both of the transmitter, the receiver, or both, to control power transmitted wirelessly between the transmitter and the receiver. | 02-25-2010 |
| 20100052811 | FLAT, ASYMMETRIC, AND E-FIELD CONFINED WIRELESS POWER TRANSFER APPARATUS AND METHOD THEREOF - In accordance with various aspects of the disclosure, a method and apparatus is disclosed that includes feature of a transmitter and receiver having a substantially two-dimensional resonator structure including a flat coil; and an impedance-matching structure operably connected to the resonator structure, the transmitter configured to transmit power wirelessly. | 03-04-2010 |
| 20100081379 | WIRELESSLY POWERED SPEAKER - In accordance with various aspects of the disclosure, a method and apparatus is disclosed that includes features of wirelessly powering a speaker. A system of coupled magnetic resonators may be used to deliver both power and audio wirelessly to a receiver/radio receiver/speaker. | 04-01-2010 |
| 20100187913 | WIRELESS POWER TRANSFER APPARATUS AND METHOD THEREOF - In accordance with various aspects of the disclosure, a method and apparatus is disclosed that includes features of transmitting power from a transmitter of a wireless power system at a multiplicity of frequencies between a first transmission frequency and a second transmission frequency at a first power level and transmitting power from the transmitter at a second power level and at one or more frequencies between the first transmission frequency and the second transmission frequency if the one or more receiving devices are determined to be coupled to the transmitter. | 07-29-2010 |
