Abstract: A transmission includes an input shaft coupled to a prime mover, a countershaft, main shaft, and an output shaft, with gears between the countershaft and the main shaft. A shift actuator selectively couples the input shaft to the main shaft by rotatably coupling gears between the countershaft and the main shaft. The shift actuator is mounted on an exterior wall of a housing including the countershaft and the main shaft. An integrated actuator housing includes a single external power access for the shift actuator. A controller interprets a shaft displacement angle, determines if the transmission is in an imminent zero or zero torque region, and performs a transmission operation in response to the transmission in the imminent zero or zero torque region.

Abstract: A method for monitoring network activity includes initiating a training phase by a machine learning (ML) server. Data associated with normal network traffic through the ML server during the training phase is collected. A classification model is generated based on the collected data. The ML server switches the training phase to an active phase. An outbound request is received during the active phase. Whether the outbound request is an anomalous request is determined based on the classification model.

Abstract: A method of analysing a skin-print comprises: receiving a skin-print on a substrate; performing a quantity test to obtain a quantity score for the skin-print; performing a chemical analysis of the skin-print to detect for the presence of one or more chemical species and thereby provide a chemical test result; and storing or transmitting the chemical test result together with the quantity score.

Abstract: This application relates to amplifier circuitry for amplifying an input signal from a MEMS capacitive sensor. The amplifier circuitry includes a first amplifier for receiving the input signal (VINP) and outputting a first output signal (VOUTP) based on the input signal. A second amplifier is configured to output a second output signal (VOUTN) which varies inversely with the first output signal. The first and second amplifier outputs are connected via first and second impedances so that a voltage at a common-mode node is equal to a common-mode voltage of the first and second output signals. The second amplifier has an input stage having an input terminal connected to a first reference voltage (VR1) and a feedback terminal connected to the common-mode node. The second amplifier also has an output stage connected between an output terminal of the input stage and the second amplifier output.

Abstract: The present disclosure provides improved packaging detection at self-checkout kiosks by identifying a given bag type for a bag selected at a self-checkout kiosk out of a plurality of bag types available from a bag dispenser associated with the self-checkout kiosk; identifying a weight range for the given bag type; in response to determining that the bag has been moved to a packing area of the self-checkout kiosk, comparing a first weight in the packing area from before the bag was moved to the packing area with a second weight in the packing area that includes the bag; and in response to a difference between the first weight and the second weight falling outside of the weight range, generating a loss prevention alert and pausing a transaction at the self-checkout kiosk.

Abstract: This application relates to methods and apparatus for operating MEMS sensors, in particular MEMS capacitive sensors (CMEMS) such as a microphones. An amplifier apparatus is arranged to amplify an input signal (VINP) received at a sense node from the MEMS capacitive sensor. An antiphase signal generator generates a second signal (VINN) which is in antiphase with the input signal (VINP) and an amplifier arrangement is configured to receive the input signal (VINP) at a first input and the second signal (VINN) at a second input and to output corresponding amplified first and second output signals. This converts a single ended input signal effectively into a differential input signal.
