Abstract: Cavitation that occurs within a pump of a machine, such as truck or other work machine, can potentially damage the pump and/or other components of the machine. The machine can have a cavitation monitor configured to detect cavitation and/or cavitation damage associated with the pump based on vibration data, speed data associated with mechanical movements of the pump, and operating data associated with the machine overall. If the cavitation monitor detects cavitation and/or cavitation damage, the cavitation monitor can cause corresponding alerts to be displayed to a machine operator or other user.

Abstract: Electromagnetic energy collecting devices are described wherein a plasmonic near field resonating system absorbs light and transfers the light energy by plasmonic near field resonance to a semiconducting material that then separates the charge. The charge is then transported out of the device, converting light energy into electrical energy. The multiple nanoparticle plasmonic resonators are closely coupled with an electrically-conductive layer that creates electromagnetic resonances that provide for near perfect absorption of the incoming light. The device can be used both as an optical sensor and as a photovoltaic electromagnetic energy to electrical energy converter.
