Abstract: A dosimeter assembly being placed within an inner volume of a test article for evaluating an image produced by an x-ray computed tomography (CT) system. The dosimeter assembly includes: a dosimeter having a display, a dosimeter shelf that supports the dosimeter; and an alignment bracket that positions the dosimeter on the dosimeter shelf. The dosimeter shelf is operable to be mounted within the x-ray computed tomography system test article, and the display of the dosimeter is viewable through a dosimeter window which is disposed at a front end of the x-ray computed tomography system test article, wherein the dosimeter assembly is accessible through an access panel directly beneath the dosimeter assembly, the access panel being an opening which is disposed on a base of the x-ray computer tomography system test article. The dosimeter is operably connected to a connection interface which is configured to exchange communication with an external device.

Abstract: Handgun holster devices are provided that allow a user to securely, comfortably and safely carry a handgun on their person. The holster may be integral with a support band configured to be worn on a body part of a user. The holster and support band may each be made from one or more flexible materials such that the device is lightweight, unobtrusive and comfortable to carry in a concealed manner. The holster includes a trigger guard that is sized, shaped and positioned to substantially cover the trigger of a holstered handgun, thereby preventing a user from inadvertently discharging the weapon.

Abstract: An ignition exciter high frequency switching converter, ignition assembly, and method of operating the same, include a high frequency switching converter operably by way of a control circuit having a timing mechanism, to operate the high frequency switching converter in discontinuous conduction mode to charge a tank capacitor for igniting an igniter.

Abstract: A method of decoupling a battery during high current cranking of an engine comprises charging a supercapacitor bank to a preselected DC supercapacitor voltage from a battery when said battery is above a preselected battery voltage, switching the supercapacitor bank to a load and switching the battery off the load, starting the engine and supplying initial voltage and current until terminal voltage of the supercapacitor is equal to terminal voltage of the battery, switching the battery into parallel with the supercapacitor, disconnecting the supercapacitor from the load, and recharging the supercapacitor to the preselected DC capacitor voltage.

Abstract: A discharge switch device is provided that includes a comparator portion, a temperature compensation diode, and a trigger portion. The comparator portion is configured to compare an input voltage value to a reference voltage value. The temperature compensation diode is configured to reduce variation of the reference voltage value. The trigger portion is configured to discharge stored energy when the input voltage value exceeds the reference voltage value.

Abstract: A system and method for decomposing ammonia from fly ash contaminated with ammonia is provided which includes maintaining the temperature of a bed of ammonia-contaminated fly ash at a decomposition temperature greater than 500° F. and less than 842° F. to decompose the ammonia from the fly ash. In a preferred embodiment, the ammonia-laden fly ash is maintained at a temperature less than a lowest carbon combustion temperature at which substantial combustion of carbon in fly ash begins to occur. A preferred embodiment includes a first chamber operating at a decomposition temperature greater than 500° F. and less than 842° F. followed by a second chamber operating at a higher carbon combustion temperature for carbon burn-out.

Abstract: A system and method for beneficiation of fly ash particles which at least partially reduces sulfur emissions includes at least one mixing reactor with a chamber and at least one exhaust, at least one fly ash source connected to provide fly ash particles to the chamber, at least one sorbent source, and at least one fluid supply system. The sorbent source provides at least one type of sorbent particles to be mixed with the fly ash particles to reduce sulfur emissions. A mass of the fly ash particles in the chamber is greater than a mass of the sorbent particles in the chamber. The fluid supply system provides at least one fluid to the chamber during a beneficiation of at least a portion of the fly ash particles in the chamber.

Abstract: The present system comprises an apparatus and a process for continuously dispersing fine particles in a liquid. The apparatus comprises a mixer that has at least on inlet for receiving the fine particles and liquid and an outlet. The mixer further comprises a barrel that has an inlet for accepting the fine particles and an outlet for dispersing the fine particles and tank for holding the liquid.
