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 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 a sender of a wireless standard compliant message modulates backchannel data on a wireless standard compliant message. The wireless standard compliant message may be addressed to an IP address of a compliant device. However the compliant message may have no meaning for the addressee. A noncompliant device within wireless range of the compliant message receives the message and demodulates the backchannel information. The noncompliant device this does not require a wireless standard radio to be on in order to receive messages and can operate at very low power.
