International Classification:

F03G 7/10

Abstract:

A water-triggered energy transformation system may include a water transportation assembly and an energy transformation assembly, wherein the water transportation assembly includes a water inlet, a water tank, a plurality of water pump, and water pipelines to transport the water from the water tank to a water outlet; and the energy transformation assembly includes a water turbine with a plurality of magnets thereon, a pair of magnetic control switches, a plurality of electromagnetic coils, a plurality of magnets, and a plurality of LED lighting fixtures. Clean water flows into the system from the water inlet and then flows to the water tank, and the water can be lifted by the water pumps to the water outlet to drive the water turbine to cause the magnets thereon to change positions to further trigger the magnetic control switches and electromagnetic coils to generate electric current to power the LED lighting fixtures.

Abstract:

Apparatus and methods for controlling physical access to a location include an entry system including at least one barrier at the physical location, with the barrier configured to selectively permit access into and/or from and/or within the physical location upon proper credentials and/or authorization. A cellular device is connected to or integrated with the entry system and is configured to transmit and receive voice and/or data information to the entry system that includes the credentials and/or authorization. The cellular device can be a retrofit to prior art/installed systems, can be external to an otherwise operational system, and/or can be integrated natively into the entry system. Methods and apparatus are disclosed to determine the power status and network link state of the cellular device and/or to establish communication through/to same, as well as for the cellular device to be connected to and control a plurality of entry systems and/or barriers. A plurality of entry systems and/or barriers can be controlled by one or more cellular devices, and the usage (and associated billing charges from cellular service providers) on any/all of those cellular devices monitored and selected to optimize (reduce) the expense of any data or other charges imposed by a cellular carrier associated with the cellular device. Optimization can include allocation to the aforementioned voice and/or data cellular plans related to specific of the plurality of entry systems and/or barriers.
