Abstract: An isolation device, a control system, and a method are disclosed. An illustrative system is disclosed to include a first power domain in which a first emitter is disposed. The system further includes a third power domain in which a second emitter is disposed. The system also includes a second power domain in which a detector is disposed, where the second power domain is electrically isolated from both the first power domain and the third power domain, where the detector is configured to receive a first control signal from the first emitter as well as a second control signal from the second emitter and produce an output in response thereto that represents a combination of the first control signal and the second control signal.

Abstract: A digital telemetry system can be calibrated to improve data communication. A receiver can receive a modulated signal with a predetermined sequence of transmitted symbols. A processing device can be communicatively coupled to the receiver for jointly performing carrier phase synchronization and symbol-timing recovery on the modulated signal to determine a corrective phase offset and a corrective timing offset. The receiver can be calibrated to use the corrective phase offset and the corrective timing offset for demodulating a subsequently modulated signal. In additional or alternative aspects, a demodulator can demodulate the modulated signal and determine an amount of interference introduced to the modulated signal. A transmitter can transmit data based on the amount of interference to a modem that transmitted the modulated signal for use by the modem to dynamically adjust hit allocation of the subsequently modulated signal.

Abstract: An example electronics module for a downhole tool includes a power source that provides an operating voltage and a processor communicably coupled to the power source to receive the operating voltage. A timer is communicably coupled to the power source and the processor and includes a real-time clock, a diode, and a capacitor. The real-time clock is powered by a primary power supply provided by the operating voltage and a backup power supply provided by the capacitor as charged through the diode. The real-time clock is powered by the primary power supply during normal operation and powered by the backup power supply when the primary power supply fails.

Abstract: A circuit for actuating a switch includes a conductive liquid switch comprising a conductive liquid droplet and a control processor configured to receive a switching signal and configured to provide at least one actuation pulse to the conductive liquid droplet to initiate movement of the conductive liquid droplet based on a duration of a time period between the switching signal and a preceding switching signal.
