International Classification:

G10K 11/00

US Classification:

181176

Abstract:

An improved acoustic lens and an improved ultrasonic transducer system comprising an improved acoustic lens and related methods are provided. The improved acoustic lens may have a uniform loss along an elevation axis or may have a loss along the elevation axis that provides for an apodization of an acoustic signal. The improved acoustic lens may be a multi-component lens. In a two-component lens embodiment, the inner lens component, for interfacing with a transducer, may have a concave outer surface and the outer lens component may have a flat or convex outer surface. In a three-component lens embodiment, the inner lens component, for interfacing with a transducer, may have a concave outer surface, the middle lens component may have a concave outer surface and the outer lens component may have a flat or convex outer surface.

Abstract:

The present disclosure provides a system and method for managing the state of charge of an energy storage system that is used as a backup power supply source in an electrical system. The energy storage system can operate in a selected mode of operation that includes a normal mode, a hibernation mode, and a suspension mode. A controller of the energy control system can determine the selected mode of operation for the energy storage system based on the current time of the day and electronic data related to a backup PV power generation system, the energy storage system, and a plurality of loads.
