摘要： Detector module designs for radiographic imaging include first and second layers of scintillator rods or pixel arrays oriented in first and second directions. The first and second directions are transversely oriented to define a light sharing region between the first and second layers. Encoding features may be disposed in, on or between the first and second layers, and configured to modulate propagation of optical signals therealong or therebetween.

摘要： A radiation detector provides improved time-resolution under consideration of an incident of a multiple scattering event. An individual comparator 11 extracts a pulse from the detection element 3a through a total circuit 12 and converts to the time data. In addition, each detection element 3a comprises the total circuit 12, that outputs the pulse totaling the output of each detection element 3a, and the total comparator 13 that converts the pulses output from the total circuit 12 to the time data. According to the aspect of the present invention, the time data suitable from each discriminated event is processed, so that the emission-time of fluorescence can be more accurately determined.

摘要： This disclosure describes an imaging radiation detection module with novel configuration of the scintillator sensor allowing for simultaneous optimization of the two key parameters: detection efficiency and spatial resolution, that typically cannot be achieved. The disclosed device is also improving response uniformity across the whole detector module, and especially in the edge regions. This is achieved by constructing the scintillation modules as hybrid structures with continuous (also referred to as monolithic) scintillator plate(s) and pixellated scintillator array(s) that are optically coupled to each other and to the photodetector. There are two basic embodiments of the novel hybrid structure: (1) the monolithic scintillator plate is at the entrance for the incoming radiation, preferably gamma rays, and the pixellated array placed behind the plate, all in optical contact with the photodetector, (2) the order of the scintillator components is reversed with the pixellated scintillation plate placed in front of the monolithic plate.

摘要： An arrangement which prevents excessive engine speed, satisfies a driver's requested torque and protects a battery from overvoltage. A control apparatus provides a torque control to a hybrid electric vehicle, and calculates an engine speed final target so that an engine speed temporary target does not exceed an upper limit. In addition, the control recalculates an engine operating point target based on the calculated engine speed final target, and calculates an engine power final target based on the recalculated engine operating point target. An electrical power target is calculated and may not exceed an upper limit for battery charging and an upper limit for battery discharging. Engine torque is controlled based on the calculated engine operating point target (especially the engine torque final target). Motor generators are controlled to operate based on the calculated engine operating point target and electrical power target.

摘要： A radiation detector that allows accurate discrimination of generating positions of fluorescence in a height direction generated in scintillation counter crystals. Specifically, the radiation detector includes scintillation counter crystals whose faces are rough surfaces. This allows suppression of unexpected partial reflection of fluorescence between adjacent scintillation counter crystals, leading to ideal spread of the fluorescence generated in a scintillator. Consequently, a radiation detector that allows accurate discrimination of the generating positions of fluorescence is provided.
