  • Method and apparatus for a high output sensor system
    Patent number: 7045930
    Abstract: The present invention relates to the field of motion/movement sensors, detectors, and/or monitors, as well as other types of sensors. In particular, the present invention may provide, for example, a large pulsed output voltage in response to very low (or slow) sensed movement or environment changes, such as, temperature, pressure, and energy. The present invention relates, for example, to other available sensors and may provide an output high enough to turn on related processing circuitry from an “OFF” state. The present invention relates, among other things, to sensing various events via, for example, axially poled homopolymer polyvinyladine fluoride (PVDF) or other piezoelectric materials.

  • DEPOSITION OF LiCoO2
    Publication number: 20070125638
    Abstract: In accordance with the present invention, deposition of LiCoO2 layers in a pulsed-dc physical vapor deposition process is presented. Such a deposition can provide a low-temperature, high deposition rate deposition of a crystalline layer of LiCoO2 with a desired (101) or (003) orientation. Some embodiments of the deposition addresses the need for high rate deposition of LiCoO2 films, which can be utilized as the cathode layer in a solid state rechargeable Li battery. Embodiments of the process according to the present invention can eliminate the high temperature (>700° C.) anneal step that is conventionally needed to crystallize the LiCoO2 layer. Some embodiments of the process can improve a battery utilizing the LiCoO2 layer by utilizing a rapid thermal anneal process with short ramp rates.

  • Reactor core monitoring system and method
    Patent number: 5171516
    Abstract: A reactor core monitoring system and method wherein: by solving the heterogenous neutron diffusion equation in an infinite lattice consisting only of the fuel segment under consideration of the fuel segments arranged in a reactor core, the local power distribution in infinite lattice and the R factor in infinite lattice used in the critical quality calculation are found beforehand, the neutron diffusion equation is solved by homogenizing each of the fuel segments in a region defined in the core and consisting of the selected fuel segment and the fuel segments surrounding the selected fuel segment. Using this solution, the local power distributions are found by correcting the previously found local power distribution in an infinite lattice consisting only of the selected fuel segment. The R factor for the selected fuel segment is then corrected, and the critical power ratio is determined using this corrected R factor.

  • Method and apparatus for converting a sootblower from a single motor to a dual motor drive
    Patent number: 7055209
    Abstract: A single motor rack and pinion driven sootblower is converted to a dual motor version. The single motor version includes a lance tube which is advanced and retracted transversely on a carriage and is further rotationally driven by a translational mechanical drive which rotates the lance tube as it is being axially driven. The conversion is accomplished by disengaging the translational drive by removing the original drive hub within the drive housing of the carriage and this original drive hub is substituted with a tubular rotary drive hub which is not in driving engagement with the translational drive when installed. A second rotational motor is then mounted on the carriage assembly and connected to externally exposed portions of the substitute hub through a gear drive for independently rotating the substitute hub and thereby independently rotating the lance tube about its axis.

  • Rapid Thermal Firing IR Conveyor Furnace Having High Intensity Heating Section
    Publication number: 20080012499
    Abstract: Isolation IR heat lamp module and method of firing multi-zone IR furnaces for solar cell processing comprising lamps disposed in individual parallel channels in a reflector/insulator body to provide a cooling air channel surrounding each tube; the channels are covered with IR-transmissive plate material to isolate each lamp from adjacent lamps and the process zone. Cooling air is exhausted and recycled upstream for energy conservation. Lamp spacing can be varied and power to each lamp individually controlled to provide infinite control of temperature profile in each heating zone. For a spike zone, and in combination with downstream quench control and annealing zones, steep heating and cooling curves with very short dwell (sharp) peak temperature profiles permit faster throughput due to operation of the lampsm at essentially 100% rated capacity, at a 2× or greater heating and throughput rate without compromising lamp life, while producing solar cells with improved output efficiency.

  • Aperiodic pseudo-random number generator based on a linear congruential generator
    Patent number: 10990355
    Abstract: The present innovative solution solves the problem of generating pseudo-random numbers that have practically infinite period, while requiring limited processing resources and operating significantly faster that known pseudo-random number generators. A sequence of pseudo-random numbers is created by a linear congruential generator using a large seed number and the sequence is used to create a big number. The big number is formed by raising each of at least two pseudo-random numbers and their sum to the same power. The big number is then selectively split into a sequence of aperiodic pseudo-random numbers which are output for use in any suitable application and for seeding the present generator.

  • Process for removing fluorine compounds from phosphoric acid
    Patent number: 3972982
    Abstract: Fluorine compounds are removed from aqueous phosphoric acid by extraction with a mixture of a silane and a long-chain hydrocarbyl amine.BACKGROUND OF THE INVENTIONThis invention relates to a process for removing fluorine from aqueous phosphoric acid.It is known that wet-process phosphoric acid obtained by acidulation of phosphate rock contains substantial amounts of fluorine, predominantly in the form of fluorine compounds such as fluorophosphates and various metal fluorides. Even following purification by known extraction processes, for example, extraction with various organic amines, ethers, etc., such phosphoric acid generally remains contaminated with undesirably high quantities of fluorine compounds with fluorine contents of 1,000 parts per million (ppm) by weight or more not being uncommon.Fluorine contents of this magnitude introduce complications relative to the use of the acid in various applications.
