  • Process of silicon tetrafluoride gas synthesis
    Patent number: 8124039
    Abstract: A process of producing silicon tetrafluoride from fluoride containing feedstocks. The process calcines the fluoride containing feedstock and a silica containing feedstock before reacting the mixture with sulfuric acid to produce silicon tetrafluoride. The silicon tetrafluoride is scrubbed with sulfuric acid. Excess sulfuric acid is recycled to the process. The process demonstrates an economic and environmentally friendly way to produce high quality silicon tetrafluoride.

  • System for initiating geospatial functional control of mobile electronics
    Patent number: 8126445
    Abstract: A system for universally controlling the functionality of portable electronic devices in a localized geospatial area is disclosed. A control signal encoded with instructions based on a predetermined protocol is sent from a RF control point transmitter. The encoded signal is received and decoded by portable electronic devices in the area and an action is performed in response to the control signal. Actions can include enabling or disabling a specific function of the portable electronic device, displaying messages on the portable electronic device, or transmitting information from the portable electronic device back to the control point. Actions remain active while in that area or for specified time periods to various levels of precision and reliability through a combination of settings or timing functions.

  • Control system for multiple fluorescent lamps
    Patent number: 8111016
    Abstract: The present invention is directed to an apparatus that drives a lighting system with multiple lamps. A phase shift mechanism is produced either by a digital method, an analog method, or a mixture of the two methods. In a digital method, phase shifts are generated by digital circuits comprising counters, a divider, an adder, and a comparator. The digital circuits analyze the signal and use the necessary information to form a series of phased driving signals. In an analog method, phase shifts are generated by analog circuits comprising ramp waveform generators, comparators, and at least one shot generator. Also, an apparatus for driving a lighting system with multiple lamps can be realized by mixing the two methods mentioned above.
