Abstract: Disclosed are devices and methods for providing solar lighting and power to a consumer using pay-as-you-go technology. The pay-as-you-go technology allows for a user to pay for home power and lighting on an incremental basis as they use the device. The payments are made using a user's cell phone. A pay-as-you-go lighting apparatus may include a lighting module configured to provide lighting to a customer when activated, and a control system including a processor and a memory configured to monitor usage of the lighting apparatus, track remaining usage credits, and disable the lighting apparatus when there are no remaining usage credits.

Abstract: Disclosed are systems, devices and methods for providing solar lighting and power to a customer by using pay-as-you-go (PAYG) technology. The PAYG technology allows a customer to make incremental payments for a solar energy system that includes a lighting unit. The payments can be made through a smartphone. A cable is used to connect an audio jack of the smartphone and a PV power jack of the lighting unit. Analog AC signals including data about activation, payment, usage and status are transmitted over the cable between the service provider and lighting unit, through a smartphone. The power jack of the lighting unit is also used to connect to a solar panel of a charging unit and a battery of the lighting unit.

Abstract: A system and method for preventing damage and undesirable situations/conditions from occurring in point of use (POU) or point of entry (POE) water systems that are not in regular use. This invention may be implemented in residential, non-residential situations or constructions where it can add value, such as commercial properties that undergo seasonal and/or other periods of disuse. In cold climate areas, faucets should be turned on and run to prevent water in the pipes from freezing, which can cause pipes to burst or leak and result in significant property damage. In all climates rust, corrosion, particles, contamination, and biofilm, can develop and/or settle in the pipes if faucets are not turned on periodically, resulting in sub-standard water quality when the system is eventually used. Also, if water is left to sit in residential pipes, other effects/conditions can take place over time that generally effect color, taste and order of the water if it does not periodically move through the system.

Abstract: A system and method for automatically monitoring water quality information directly by using sensors to test water in a plumbing system or indirectly by monitoring government or other warnings that can be received wireless or over wireline. In response the system and method identify a water treatment/enhancement protocol and perform this protocol on the water supply in the house/building.
