Abstract: The present disclosure relates to configuring at least one pair of devices in a physical unclonable function (PUF) apparatus and reading out at least one pair of devices for determining a persistent random PUF output. The pair of devices may be readout by measuring a physical difference between the devices/components caused by random manufacturing differences, which may then be used to determine a persistence random PUF output. Configuring the pair of devices includes measuring the random manufacturing difference and, based on that measurement, setting a readout condition for the pair of devices, which dictates aspects of the readout process that should be used for that pair of devices. Each time the pair of devices is readout in the future, it may be readout in accordance with the condition that was set at configuration.

Abstract: A magnetic angle measurement system having magnetic angle sensors, signal processing circuitry and a processor is disclosed. First signal processing circuitry receives a first subset of outputs of a first plurality of outputs from a first magnetic angle sensor and determines first magnetic angle data based on the received first subset of outputs. Second signal processing circuitry receives a second subset of the outputs from the first magnetic angle sensor and determines second magnetic angle data based on the received second subset of outputs. Third signal processing circuitry receives a second plurality of outputs from the second magnetic sensor and determines third magnetic angle data based on the received second plurality of outputs. The processor compares the magnetic angle data and determines a processing result based on the comparison, where fault tolerance resolution of the magnetic angle measurement system is based at least in part on the processing result.

Abstract: Aspects of the present application allow for measurement of a calibrated resistance for a resistive film in a sensing element, such that effects from contact resistance and background resistance drifts due to factors such as temperature, strain or aging can be reduced or eliminated. In some embodiments, by taking a plurality of two -terminal resistance measurements between various pairs of electrodes on a resistive film, a contact-resistance- independent resistance of a reference portion of the resistive film can be determined. Further, a contact-resistance-independent resistance of a sensing portion of the resistive film can be determined based on a plurality of two -terminal resistance measurements between pairs of electrodes. The resistance of the reference portion can be removed from the measured resistance of the sensing portion, such that variations in the reference portion resistance that are not caused by a sensed environmental condition may be compensated.

Abstract: Described herein are techniques of characterizing electrical characteristics of a battery cell. The techniques employ a battery monitor coupled to a battery to measure voltage of the battery cell when it is in a recovery state after application of a stimulus (e.g., discharging or charging the battery). The measured voltage of the battery cell in the recovery state is then used to generate a characterization of the battery cell. The characterization may be used, for example, to match the battery cell with one or more similar battery cells to be coupled in a battery pack. In another example, the characterization may be used to verify authenticity of the battery cell.

Abstract: Embodiments of the present disclosure describe frequency detection techniques for detecting power irregularities. These irregularities may include variations or abnormalities in switched-mode power supply circuit switching behavior, power spikes, and/or output oscillations. The frequency detection techniques may compare different frequency components of the power signal to detect irregularities.

Abstract: Provided herein are delay locked loops (DLLs) with calibration for external delay. In certain embodiments, a timing alignment system includes a DLL including a detector that generates a delay control signal based on comparing a reference clock signal to a feedback clock signal, and a controllable delay line configured to generate the feedback clock signal by delaying the reference clock signal based on the delay control signal. The timing alignment system further includes a delay compensation circuit that provides an adjustment to the controllable delay line to compensate for a delay of the feedback clock signal in reaching the detector.

Abstract: A method and apparatus are provided for generating a directional output signal from sound received by at least two microphones arranged as microphone array. The method includes transforming the sound received by each of said microphones and represented by analog-to-digital converted time-domain signals provided by each of said microphones into corresponding complex-valued frequency-domain microphone signals each having a frequency component value for each of a plurality of frequency components, wherein one of said complex-valued frequency-domain microphone signals is selected as a frequency domain reference signal, calculating, for each of the plurality of frequency components, real-valued Wind Reduction Factors as minima of the reciprocal and non-reciprocal frequency components of a plurality of real-valued Deviation Spectra if said minimum is below a preselected deviation threshold and set to one if said minimum is above or equal to said deviation threshold, and for each of the plurality of frequency components, said Wind Reduction Factors are multiplied with the frequency component values of said frequency-domain reference signal, forming a frequency-domain wind-reduced output signal.
