A method for locating an RFID transponder is proposed. The method comprises generating a plurality of measurement signals based on a magnetic field measured by a plurality of sensors. The method further comprises determining a respective degree of correlation for each of the plurality of measurement signals with a reference signal. The reference signal is based on a data sequence assigned to the RFID transponder. In addition, the method comprises determining a position of the RFID transponder based on the degrees of correlation of the plurality of measurement signals.

The invention relates to systems and methods for obtaining phase information and/or localization of tag devices. In particular, the invention relates to a system for the localization of at least one tag device, the system including: the at least one tag device configured to transmit a tag signal which is a frequency-hopping signal; at least one known position device configured to transmit a reference signal; and a localization device configured to localize the at least one tag device based on the phase difference of arrival, PDoA, of the tag signal and the reference signal.

Embodiments of the present invention provide a mobile device having a receiver and an orientation determiner. The receiver has a plurality of antennas for receiving a signal from a stationary transmitter. Each antenna of the plurality of antennas is arranged to have a different receiving direction. The receiver is configured to detect a signal strength of the signal received with each antenna in order to obtain a plurality of detected signal strengths. The orientation determiner is configured to determine an orientation of the mobile device relative to the stationary transmitter based on the plurality of detected signal strengths.

In a method and a device for determining a physical quantity from a number of measured values containing errors, grouping of the number of measured values containing errors into a plurality of subgroups of measured values is executed, wherein each subgroup includes a redundancy, so that more measured values than the number of measured quantities are contained in each subgroup. Hereupon, a reliability quantity for each subgroup is calculated based on the redundancy contained in the subgroup. Further, individual evidence is allocated to the measured values containing errors of each subgroup based on the reliability quantity for the respective subgroups. An evidence determiner determines one overall evidence each for each measured value containing errors based on the individual evidence quantities for a respective measured value. Hereupon, a processor calculates the physical quantity using at least some of the measured values containing errors and at least some of the overall evidences.

A device for predicting a loss of control over a muscle of a human being has a detector for detecting a sound of the muscle, an acquirer for acquiring an acceleration of the human being and an evaluator for evaluating the sound and the acceleration to determine an imminent loss of control over the muscle from the sound and the acceleration.

In a method for estimating a deviation between a free-running transmitter clock and a reference clock, at a receiver stationary with respect to a transmitter, a transmitter signal generated by the transmitter on the basis of the transmitter clock is received. On the basis of the reference clock, a time of arrival of the transmitter signal and a beat phase of the transmitter signals carrier is determined. On the basis of a clock error model, the time of arrival and the beat phase, the deviation between the transmitter clock and the reference clock is estimated. The clock error model is derived by fitting a correlation function of a stochastic model to a measured auto correlation function of the transmitter clock. Deviations for a plurality of transmitters may be estimated and the transmitters may be virtually synchronized based on the estimations.
