Abstract: An energy storage and power supply device includes an energy storage unit, a sensor, an output, a regulator, and a processing circuit. The energy storage unit is configured to store electrical energy. The sensor is positioned to acquire data indicative of an operating characteristic of the energy storage unit. The output is coupled to the energy storage unit and configured to provide power from the energy storage unit to a load. The regulator is positioned along a power flow path between the energy storage unit and the output. The regulator is configured to facilitate selectively restricting a power flow provided to the output. The processing circuit is configured to monitor the operating characteristic of the energy storage unit based on data from the sensor and provide a signal to the regulator to restrict the power flow provided to the output in response to the operating characteristic satisfying a threshold.

Abstract: A portable speaker assembly includes a body, a speaker, and a membrane. The body includes a first plate spaced from a second plate, and a surface of the body defines a port having a first cross-sectional area. The speaker is disposed along a surface of the first plate and extends toward the second plate. The membrane is configured to direct sound waves toward the port and is positioned between the first plate and the second plate. The membrane has a second cross-sectional area that is larger than the first cross-sectional area of the port.

Abstract: A positioning system for a solar panel includes a frame, a surface plate, an adjustable rail and a frame coupling. The surface plate is configured to secure the positioning system to a mounting surface and includes a connection for an axle. The axle links the surface plate with the frame coupling or with the adjustable rail. The frame coupling attaches to the frame and holds the frame in an operating position. A length of the adjustable rail may be increased or decreased for varying the angular orientation of the frame relative to the mounting surface. The frame is configured to be removable from the frame coupling without requiring the surface plate to be removed from the mounting surface.
