Abstract: The present disclosure provides systems and methods for signal processing and detection for pacemaker pulses. Systems and methods can activate an analog-to-digital converter based on detecting a leading edge of a pacemaker pulse. Such use of the analog-to-digital converter may allow a system to operate at a lower power and with more specificity than certain other systems.

Abstract: Aspects of this disclosure relate to symbol based envelope tracking. A voltage modulator circuit can generate an output bias voltage that tracks a root mean square symbol power of a radio frequency signal. A crest factor reduction circuit in a signal path that provides the radio frequency signal can adjust a crest factor reduction threshold such that the crest factor reduction threshold corresponds to the output bias voltage.

Abstract: Aspects of this disclosure relate to symbol based envelope tracking. A voltage modulator circuit can generate an output bias voltage that tracks a root mean square symbol power of a radio frequency signal. A digital predistortion system in a signal path that provides the radio frequency signal can adjust a digital predistortion based on a symbol based envelope tracking state.

Abstract: An electrochemical sensor is provided which may be formed using micromachining techniques commonly used in the manufacture of integrated circuits. This is achieved by forming microcapillaries in a silicon substrate and forming an opening in an insulating layer to allow environmental gases to reach through to the top side of the substrate. A porous electrode is printed on the top side of the insulating layer such that the electrode is formed in the opening in the insulating layer. The sensor also comprises at least one additional electrode. The electrolyte is then formed on top of the electrodes. A cap is formed over the electrodes and electrolyte. This arrangement may easily be produced using micromachining techniques.

Abstract: A source stochastic signal is deconstructed into one or more components using a decomposition process. The decomposition process deconstructs the source stochastic signal into at least one component which encodes the oscillatory behavior of the source stochastic signal. The one or more components are mapped, using one or more trained models, to a pair of target components which encode the estimated oscillatory behavior and estimated steady-state behavior of a target stochastic signal. The target stochastic signal is then reconstructed from the oscillatory behavior target signal by shifting the oscillatory behavior target signal so that its average value aligns with the average value of the steady-state behavior target signal. The source stochastic signal and the target stochastic signals can be biological signals having a related or common origin, such as photoplethysmogram (PPG) signals and arterial blood pressure (ABP) waveforms.

Abstract: A semiconductor fabrication control system and method of operation can include: detecting a status with a control board communicatively coupled to a semiconductor fabrication tool; collecting process information from the semiconductor fabrication tool with the control board based on the status changing or a predetermined time elapsing; storing the process information to a server with the control board communicatively coupled to the server by a network connection; and engaging an auto-stop mechanism of the semiconductor fabrication tool to prevent the semiconductor fabrication tool from running based on the process information being wrong.

Abstract: Apparatus and methods for RF signal limiters with diode-enhanced limiting are provided. In certain embodiments, an RF signal limiter includes a field-effect transistor (FET) stack electrically connected between an RF signal path and a limiting node, such as ground. The FET stack includes a first or topmost FET having a drain connected to the RF signal path. The gate of the topmost FET is biased through a first gate resistor. The RF signal limiter further includes a first forward enhancement diode having an anode connected to the RF signal path and a cathode connected to the gate of topmost FET.

Abstract: Aspects of this disclosure relate to generating a bias signal with magnetic field cancellation. A voltage modulator circuit can generate a bias voltage that tracks an envelope of a radio frequency signal. For example, the bias signal can track the envelope of the radio frequency signal that is amplified by a power amplifier on a symbol-by-symbol basis. The voltage modulator circuit includes one or more pairs of switches with magnetic field cancellation.

Abstract: An apparatus and methods for detecting seat occupancy of a vehicle including a plurality of seats, one or more microphones, and one or more loudspeakers are described. The apparatus in the vehicle includes a digital signal processor coupled to a memory and configured to: determine a first set of transfer functions between the one or more microphones and the one or more loudspeakers based on a first audio signal played from the one or more loudspeakers while passengers are occupying one or more of the plurality of seats. The digital signal processor is configured to apply at least the first set of transfer functions and a second set of transfer functions for the vehicle to a neural network trained on transfer functions for a type of the vehicle to predict a seat occupancy of each of the plurality of seats based on the transfer functions.
