    Abstract: A system and method of controlling inductive power transfer in an inductive power transfer system and a method for designing an inductive power transfer system with power accounting. The method of controlling inductive power transfer including measuring a characteristic of input power, a characteristic of power in the tank circuit, and receiving information from a secondary device. Estimating power consumption based on the measured characteristic of tank circuit power and received information and comparing the measured characteristic of input power, the information from the secondary device, and the estimated power consumption to determine there is an unacceptable power loss. The method for designing an inductive power transfer system with power accounting including changing the distance between a primary side and a secondary side and changing a load of the secondary side. For each distance between the primary side and the secondary side and for each load, measuring a circuit parameter on the primary side in the tank circuit and a circuit parameter on the secondary side during the transfer of contactless energy. The method further including selecting a formula to describe power consumption in the system during the transfer of contactless energy based on coefficients and the circuit parameters, and determining the coefficients using the measured circuit parameters.

    Abstract: A communication system that uses keyed modulation to encode fixed frequency communications on a variable frequency power transmission signal in which a single communication bit is represented by a plurality of modulations. To provide a fixed communication rate, the number of modulations associated with each bit is dynamic varying as a function of the ratio of the communication frequency to the carrier signal frequency. In one embodiment, the present invention provides dynamic phase-shift-keyed modulation in which communications are generated by toggling a load at a rate that is a fraction of the power transfer frequency. In another embodiment, the present invention provides communication by toggling a load in the communication transmitter at a rate that is phase locked and at a harmonic of the power transfer frequency. In yet another embodiment, the present invention provides frequency-shift-keyed modulation, including, for example, modulation at one of two different frequencies.

    Abstract: Systems and methods for approximating caloric energy intake and/or macronutrient composition using thermogenesis. The system may include one or more sensors for tracking body temperature over a period of time, and may include a processor configured to determine caloric energy intake and/or macronutrient composition based on body temperature. The system may be configured to normalize body temperature readings to compensate for factors other than thermogenesis that might affect core body temperature. The system may include one or more sensors for measuring normalization factors, and a processor for normalizing raw body temperature readings based on the measured normalized factors. The method may include the steps of: (a) collecting body temperature data, (b) normalizing the raw body temperature data and (c) determining caloric energy intake and/or macronutrient composition from the normalized data. The system may be configured to account for user calibration data when characterizing macronutrient composition.
