    Abstract: A level transmitter includes an analog-to-digital convertor clock signal generator that receives a transmitter clock signal that is used to establish when an incident signal is transmitted toward a material boundary. The analog-to-digital convertor clock signal generator uses the received transmitter clock signal to generate an analog-to-digital convertor clock signal. An analog-to-digital convertor samples an analog waveform based on the analog-to-digital convertor clock signal and generates a digital value for each sample of the analog waveform. An analysis module analyzes the digital values to determine a distance to the material boundary.

    Abstract: A field device assembly comprises a first process sensor, a wireless transceiver, and a processor. The first process sensor is disposed to sense a first process parameter. The wireless transceiver is configured to communicate wirelessly with a network manager. The processor is configured to process the sensed first process parameter, and to command the wireless transceiver and first process sensor to perform a first resource-intensive activity according to a first commissioned adaptive schedule whereby rates of the resource-intensive activity vary over time and/or based on sensed events.

    Abstract: A device includes a radio operating on a predetermined schedule, and a battery configured to supply power to the radio for radio operation. A radio controller is configured control to radio operation. A voltage indicating circuit is configured to monitor a voltage of the battery, and to provide an output signal indicative of a battery voltage sufficient to power radio operation. When the output signal is active, the radio controller allows operation of the radio on the predetermined schedule. When the output signal is inactive, the radio controller adjusts operation of the radio to maintain radio operation.
