Abstract: Anomaly detection techniques in time series data are described. The techniques can model historical sensor data for a training period using a non-iterative acceleration technique for systems of non-linear equations. The model can include a Bayesian statistical model. The warmup period for training the model can be reduced or bypassed by setting the initial parameters of the model. The trained model can predict a confidence range for a forecast period. Measured values in the forecast period can then be compared to the confidence range to determine the presence of anomalies.

Abstract: A status of one or more components of a battery monitor circuit can be evaluated, such as to validate operation of the monitor circuit. In an example, a battery monitor circuit can be evaluated by providing a first test signal to a battery voltage measurement circuit that is coupled to a battery. A first analog-to-digital converter (ADC) circuit can be configured to receive a first voltage signal from the battery voltage measurement circuit in response to the first test signal. A processor circuit can be configured to validate the first ADC circuit by evaluating a correspondence between the first test signal and the received first voltage signal. One or more other ADC circuits in the battery monitor circuit can be validated by cross-checking measurement results with information from the first ADC circuit.

Abstract: The present disclosure provides a magnetoresistive quadrant detector for use in a magnetic sensing device comprising a magnetic multi-turn sensor and an angle turn sensor, in particular, an angle sensor configured to provide 180° absolute angle measurements, such as an anisotropic magnetoresistive (AMR) angle sensor. The quadrant detector is formed of at least two magnetoresistive elements, preferably giant magnetoresistive (GMR) elements, which may be integrated to the multi-turn sensor die or provided on a separate die within the sensor package. The magnetoresistive elements are configured to provide a unique combination of resistance states for each quadrant of magnetic field direction. This quadrant information can then be used to remedy any ambiguities in the multi-turn measurement without needing 360° absolute angle information from the single turn angle sensor.

Abstract: An amplifier circuit comprises a first gain circuit path configured to provide a first signal gain to an input signal, a second gain circuit path configured to provide a second signal gain to an input signal, an auxiliary gain circuit path configured to provide an auxiliary signal gain to an auxiliary input signal, wherein the auxiliary signal gain is equal to the first signal gain minus the second signal gain, a summing circuit configured to sum the second gain signal path and the auxiliary signal path, and logic circuitry configured to change an output of the circuit between the first gain circuit path and the sum of the second gain signal path and the auxiliary signal path, and set the auxiliary input signal equal to the input signal before the changing.

Abstract: Systems configured to implement semi-closed wireless data transfer for rotary joints are disclosed. An example system includes first and second RF transceivers, to be included in different components of a rotary joint. The first and second RF transceivers implement elliptically (e.g., circularly) polarized antennas to realize a short distance communication link (e.g., a 60 GHz short distance communication link) between the two components of a rotary joint. The example system further includes an open-ended waveguide (OEWG) between the first and second RF transceivers, for receiving, at a first end of the OEWG, wireless signals transmitted by one of the first and second RF transceivers, transmitting the received signals through the OEWG, and radiating, at a second end of the OEWG, wireless signals indicative of the received wireless signals, to be received by another one of the first and second RF transceivers.

Abstract: A memory device comprising a memory array including memory cells to store memory data, error correcting code (ECC) circuitry configured to generate ECC data and use the ECC data to detect errors in the memory data, and an ECC circuitry checker. The ECC circuitry checker is configured to substitute the ECC data with check ECC data, compare an output of the ECC circuitry to an expected output when the substituted check ECC data is applied to the ECC circuitry, and generate an alert when the comparing indicates an error in the ECC circuitry.

Abstract: A reference electrode of an electrochemical sensor includes a substrate having internal walls defining a well and a channel. The reference electrode includes a conductive element disposed in the substrate. The well extends from a first surface of a substrate towards a second surface of the substrate. The channel is within the substrate. The channel has a first end connected to the well and a second end that is in contact with the conductive element. The reference electrode may include an additional well that extends from the first surface towards the second surface. The additional well may be connected to the second end of the channel and may be in contact with the conductive element. The channel and the wells form a flow path of a conductive medium. The flow path may be coupled to an agitating element or heating element that promotes flow of the conductive medium.

Abstract: A capacitive amplifier device and technique for mitigating the perturbation within the switchable terminals of a feedback capacitor which is produced by the switching activity performed as part of the device's operation. The capacitive amplifier contains feedback components which can be switched without producing significant kickback or poorly behaved transitions due to the inclusion of at least one dedicated circuit. The dedicated circuit is a kickback limiter circuitry which is connected to a switchable node and is designed to reduce the kickback. The technique for reducing the kickback produced can be achieved by connecting and activating the kickback limiter circuitry.
