Abstract: Devices, systems, and techniques are described that relate to the monitoring of various types of components in industrial systems. These include battery-less monitors that run on power harvested from their environments, systems for acquiring monitor data for the components in a facility, and/or techniques for processing monitor data to reliably determine the status of individual components and other system parameters.

Abstract: Monitors are for pressurized systems are described. These may include batteryless monitors that run on power harvested from their environments.

Abstract: A wake-up radio system in a wireless sensor network, the wake-up radio comprising: an analog front end configured to communicate with matching network; an analog to digital converter coupled to the analog front end; and a digital baseband coupled to the analog to digital converter, wherein the digital baseband outputs a fast wake-up signal and a secure wake-up signal, and wherein the wake-up radio listens to all channels simultaneously.

Abstract: Circuits and techniques are described that relate to an “energy operating system” for tracking available energy and energy consumption in a system or device to support a wide range of power management and related functionalities.

Abstract: Devices, systems, and techniques relating to steam trap monitoring are described. These include battery-less steam trap monitors that run on power harvested from their environments, systems for acquiring steam trap monitor data for the traps in a facility or across multiple facilities, and techniques for processing steam trap monitor data to reliably determine the status of individual steam traps and potentially other system parameters.

Abstract: Embodiments of the invention include a wakeup receiver (WRX) featuring a charge-domain analog front end (AFE) with parallel radio frequency (RF) rectifier, charge-transfer summation amplifier (CTSA), and successive approximation analog-to-digital converter (SAR ADC) stages. The WRX operates at very low power and exhibits above-average sensitivity, random pulsed interferer rejections, and yield over process.

Abstract: In some embodiments, an apparatus includes an integrated circuit such as a system on chip that operates in part from harvested power and that uses information about power harvesting conditions to alter a power-on sequence or boot sequence based on that information. In some embodiments, a method uses information about power harvesting and energy harvesting conditions to alter a power-on sequence or boot sequence.

Abstract: Embodiments include methods and apparatus for wireless network communication between a device that operates a radio in compliance with a wireless communication standard and another device that may not be capable of complying with the wireless communication standard. In an embodiment the non-complaint device is a receiver only. Information is broadcast or advertised or otherwise transmitted by the compliant device according to the protocol and embodiments encode information on top of the protocol for decoding by the receiving device, which does not decode the protocol.
