  • Publication number: 20170130649
    Abstract: A cleaning system and method use an ultrasound probe, a coupling mechanism, and a controller to clean equipment of a vehicle system. The ultrasound probe enters into an engine. The ultrasound probe emits ultrasound pulses and the coupling mechanism provides an ultrasound coupling medium between the ultrasound probe and one or more components of the engine. The controller drives the ultrasound probe to deliver the ultrasound pulse through the coupling medium to a surface of the one or more components of the engine. The ultrasound probe delivers the ultrasound pulse to remove deposits from the one or more components of the engine.

  • Publication number: 20170025996
    Abstract: Switching interference is a primary artifact which affects the accuracy of arc detectors. To address switching interference, conventional arc detectors employ computationally intensive techniques which are often designed specifically for a target application. Thus, conventional arc detectors require a significant amount of hardware to accurately detect arc faults, which can increase costs of the power systems and prohibit wide deployment of arc detectors. With improved signal processing, a unique method for arc detection can accurately detect arc faults efficiently while tolerate switching interference from an inverter of the power system. Specifically, the method provides accurate but efficient arc detection by using a small Fast Fourier Transform with coherent sampling that is accomplished with a common clock generator in combination with signal conditioning. The overall system implementing the method is also programmable to suit a variety of target applications.

  • Publication number: 20160356893
    Abstract: A radio-chromic film dosimeters based on polystyrene binder and dithizone dye are invented for high dose applications. The dose response of Dz-PS film dosimeters increases linearly with increase absorbed dose up to 100 kGy. The dose sensitivity of the films increases strongly with increase of concentrations of dithizone dye. The effects of irradiation temperature, relative humidity, dose rate and the stability of the response of the films after irradiation were investigated and found that these films could be used as routine dosimeter in industrial radiation processing.

  • Patent number: 9365780
    Abstract: A method and process to remove sulfur compounds from a real fuel product of straight-run diesel (SRD) by the action of ozone bubbling and tert-butyl hydroperoxide (t-BUOOH) under normal laboratory conditions is disclosed. Slight desulfurization is taken place after ozone bubbling process which may be assigned to a removal of sulfur compounds in a gaseous form (SOx). Most of the organically bound sulfur and/or elemental sulfur and hydrogen sulfide still exist in the ozonized samples. Sulfur removal from SRD samples was achieved by combining ozone bubbling with extraction by using different solvents to remove the oxidized sulfur compound (polar) from ozonized samples. This method provides a considerable level of total sulfur reduction where the reduction of sulfur reaches 93%.

  • Patent number: 9234081
    Abstract: NBT-PVA film dosimeters performance is affected due to high humidity levels. NBT-PVB film dosimeters with a relatively small effect of high humidity levels on its performance are invented. NBT-PVB film dosimeters are made by using alcoholic solution to dissolve both of NBT and PVB. The films are very useful for routine dosimeter in industrial radiation processing. A very high sensitivity NBT-PVB Radio-chromic film dosimeter is achieved due to high solubility of NBT dye in 2-methoxyethanol enabling the addition of very high concentrations of NBT dye in the film dosimeters. The dose response of conventional NBT-PVA dosimeter films are normally saturated after 50 kGy, while the invented composites of NBT-PVB dosimeter films demonstrated high dose range up to 100 kGy for high dose industrial use.

    Abstract: A memory mechanism for providing semaphore functionality in a multi-master processing environment is disclosed. An exemplary memory unit includes a memory controller that manages access to a shared memory. The memory controller includes a semaphore context monitor associated with each master having access to the shared memory. A semaphore context monitor associated with a semaphore-capable master is activated by the semaphore-capable master (for example, by exclusive request signal(s) received by memory controller from semaphore-capable master). A semaphore context monitor associated with a non-semaphore-capable master is activated by the memory controller (for example, by exclusive request signal(s) generated by the memory controller).
