A photovoltaic power conditioning circuit for providing power from a photovoltaic device to an alternating current mains power supply line, the circuit comprising: a DC input to receive DC power from said photovoltaic device; an AC output configured for direct connection to said AC mains power supply line; a DC-to-AC converter coupled to said DC input and to said AC output to convert DC power from said photovoltaic device to AC power for output onto said power supply line; and an electronic controller directly coupled to said power supply line to measure a voltage of said power supply line and a current in said supply line and to control said DC-to-AC converter responsive to said measuring. | 09-12-2013 |
20130279210 | Power Conditioning Units - We describe a power conditioning unit with maximum power point tracking (MPPT) for a dc power source, in particular a photovoltaic panel. A power injection control block has a sense input coupled to an energy storage capacitor on a dc link and controls a dc-to-ac converter to control the injected mains power. The power injection control block tracks the maximum power point by measuring a signal on the dc link which depends on the power drawn from the dc power source, and thus there is no need to measure the dc voltage and current from the dc source. In embodiments the signal is a ripple voltage level and the power injection control block controls an amplitude of an ac current output such that an amount of power transferred to the grid mains is dependent on an amplitude of a sinusoidal voltage component on the energy storage capacitor. | 10-24-2013 |

20150294403 | SYSTEMS AND METHODS FOR VEHICLE FLEET SHARING - The disclosed technology relates generally to methods and systems for sharing vehicles between fleets. Vehicle sharing services typically experience the most use during the weekend. Thus, many vehicles used by vehicle sharing services sit idle during the week. Meanwhile, vehicle rental companies experience the most demand during the week and their vehicles are underutilized during the week. The disclosed technology, in certain embodiments, provides systems and methods for sharing vehicles between a vehicle sharing entity and a vehicle renting entity. This allows the entities to lower fleet costs and obtain better fleet utilization by moving vehicles between fleets when one entity anticipates a spike in demand. For example, the ability for the vehicle sharing service to utilize a rental vehicle agency's excess weekend inventory will allow them to meet its strong weekend demand without the need for purchasing and maintaining additional vehicles. | 10-15-2015 |

20110320134 | Smart Faucet and Water Filtration System and Method - 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.

20120004778 | Vacation Faucet Apparatus and Method - 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. | 01-05-2012 |
