Abstract: An energy harvesting device utilizing a monolithic, mesoscale, single-degree-of-freedom inertial based resonator in which the support structure, beam-spring, and proof mass are a single component without joints, bonds, or fasteners. Frequency tuning features include holes in the proof mass in which mass can be added to change the devices resonance frequency as well as levers which add curvature to the beam-spring system and adjust system stiffness. Robustness is increase by designing the resonator to exhibit nonlinear behavior such that its power density is maximized for low vibration amplitudes and minimized for high amplitudes. The device structural resonance modes are designed to be much higher than the resonators proof mass-spring resonance frequency. Electromechanical transducers are used to convert the resonators mechanical energy to electrical energy. Electrical circuitry is included to extract and condition the electrical charge.

Abstract: A wireless edge device is operable in a wireless network and configured to communicate with other wireless devices in the wireless network. The wireless edge device includes a processor configured to receive an input to switch from a low power consumption normal operation mode to a site survey mode, a transceiver configured to (i) transmit data packets periodically or asynchronously to a wireless device of the wireless network, and (ii) receive the data packets returned by the wireless device, and a visual indicator. The processor is further configured to evaluate quality and/or reliability of the received data packets, to provide a signal to the visual indicator indicative of signal strength at the wireless edge device based on the evaluation of quality and/or reliability of the received data packets, and to switch from the site survey mode to the low power consumption normal operation mode after a predetermined time.
