Abstract: A wireless charging in-band communication system includes a channel encoding for message error correction and detection. A modulation module performs biphase modulation for DC balanced signals and impedance switching to change reflected impedance seen by the source. A synchronization module prepends the message with a synchronization sequence having Golay complementary codes. A receiver module receives the message from the transmitter module. A preamble detection block has a Golay complementary code correlator used for message detection, synchronization, and equalization coefficient estimation and selection. A decoding module that performs biphase demodulation with error correction with a DC offset being estimated as the average value of the signal over the length of the message before channel decoding. The decoding module performs equalization, error correction and detection channel decoding.

Abstract: A tunable microwave network and its application in a radio transceiver transmit signal cancellation network is described. The tunable microwave network realizes a large set of reflection coefficients over a predefined area in the complex reflection coefficient plane for the purpose of reflecting a variable cancellation signal which, when properly configured, results in the substantial attenuation of transmit reflection and transmit leakage signal at the radio transceiver receiver input. A relevant building block of the proposed tunable microwave network is a shunt tunable capacitive element coupled to another shunt tunable capacitive element through a phase shifting element with phase shift greater than 30 degrees divided by a quantity substantially similar to the total number of said tunable capacitive elements and less than 60 degrees at a predefined frequency.

Abstract: The operation of a conventional cellular telecommunications transceiver that forms part of a vehicle's telematics system can be selectively changed in order to provide telephone calls by providing the transceiver with a second and different SIM card. Providing a second SIM card, however, will disable telematics service that can include stolen vehicle tracking. A personal identification number or PIN is thus required in order for the information that is stored in an external, user-provided SIM card to be used by a telematics system transceiver rather than the information stored in a built-in SIM card that is provided by a telematics system operator/provider.

Abstract: A utensil storage monitoring system comprising a microprocessor, a serving utensil sensor in signal communication with the microprocessor, a clocking circuit and at least one alerting component. The system identifies when a serving utensil is removed from a serving utensil holster or a serving utensil rest and initiates the clocking circuit. The system monitors the status of the serving utensil and the passing time. When the passing time exceeds a predetermined allowable “in-use” time period, the system initiates an alert. The alert can be a visual alert, an audible alert, or any other alert. The alert can escalate if the serving utensil is not returned to the holster/rest in a timely manner. The system can associate a specific serving utensil with the respective monitoring system to avoid cross contamination. The system can additionally include a sterilization component. The system can be integrated into a utensil status and data acquisition system.
