Publication number: 20140021356Abstract: A detector (22) detects an event. First and second time-to-digital converters (TDCs) (70, 72) generate first and second time stamps (TS1, TS2) for the detection of the event.

The detector may be a detector array, and trigger circuitry (28) propogates a trigger signal from a trigger detector of the array of detectors to the first and second TDC's. Skew correction circuitry (132, 134, 136, 142, 60, 162) adjusts a timestamp (TS) based on which detector is the triggering detector.Type: ApplicationFiled: March 29, 2012Publication date: January 23, 2014Applicant: KONINKLIJKE PHILIPS N.V.Inventors: Bernardus Antonius Maria Zwaans, Thomas Frach

Publication number: 20140021357Abstract: The inversion algorithm based on the maximum entropy method (MEM) removes unwanted effects in high energy imaging which result from an uncollimated source interacting with a finitely thick scintillator. The algorithm takes as an input the image from the thick scintillator (TS) and the radiography setup geometry. The algorithm then outputs a restored image which appears as if taken with an infinitesimally thin scintillator (ITS). Inversion is accomplished by numerically generating a probabilistic model relating the ITS image to the TS image and then inverting this model on the TS image through MEM. This reconstruction technique can reduce the exposure time or the required source intensity without undesirable object blurring on the image by allowing the use of both thicker scintillators with higher efficiencies and closer source-to-detector distances to maximize incident radiation flux.Type: ApplicationFiled: July 18, 2013Publication date: January 23, 2014Inventors: Han WANG, James M.

Publication number: 20140021361Abstract: In the radiation detector, a capacitor is connected between a connecting wire which is connected with a preamplifier (amplifier) and another connecting wire. Specifically, the capacitor is connected between the connecting wire and another connecting wire which has the lowest electric resistance with respect to a signal wire among connecting wires connected with a radiation detecting element. This prevents electric current produced by static electricity from flowing to the signal wire and prevents the signal wire or the preamplifier from being damaged by static electricity. A circuit element for a countermeasure against static electricity is not provided at the signal wire, and therefore input capacitance of the preamplifier is kept low. Accordingly, the radiation detector is improved by a sufficient countermeasure against static electricity while input capacitance of the preamplifier is kept low.Type: ApplicationFiled: July 19, 2013Publication date: January 23, 2014Inventors: Kengo YASUI, Yuji OKUBO

Publication number: 20140021390Abstract: A non-interchangeable two-component connecting valve capable of connecting a fuel supply to a fuel cell or other device is disclosed. One component of the connecting valve comprises at least one center post and one internal elastomeric seal, which opens when moved or compressed by a correctly sized and dimensioned mating tube from the other component. In one embodiment, only one valve component has one or more internal seals. In alternate embodiments, both valve components have one or more internal seals, which can open simultaneously or sequentially.Type: ApplicationFiled: September 20, 2013Publication date: January 23, 2014Applicant: Societe BICInventors: Andrew J. Curello, Paul Spahr

Publication number: 20140021391Abstract: Apparatus, including a diaphragm valve, is provided featuring a valve body, a diaphragm, a pressure ring, and at least one elastomeric member. The valve body may include a circumferential flange. The diaphragm may include a circumferential gasket portion configured to be seated on the circumferential flange so as to form a joint between the valve body and the diaphragm. The pressure ring may include concentric fluctuations, and may be configured to apply a sealing force against the joint so that the concentric fluctuations prevent radial movement of the circumferential gasket portion and the circumferential flange. The elastomeric member may be configured to respond to a compressive force and provide a substantially constant sealing force, transmitted through the pressure ring, regardless of small variations in the thickness or material dimensions of the circumferential gasket portion caused by temperature fluctuation or material flow and age.Type: ApplicationFiled: July 20, 2012Publication date: January 23, 2014Applicant: ITT MANUFACTURING ENTERPRISES LLCInventors: Louis E. MATALON, Ronald G. BUTLER

Publication number: 20140021392Abstract: A diaphragm valve features a valve body having a fluid flow channel with a weir portion to control the flow of fluid through the fluid flow channel; a diaphragm that responds to a closing or force to make sealing contact with the weir portion to interrupt said flow, or to release the sealing contact with the weir portion to allow the flow; a compressor configured to apply the closing or force in order to interrupt or allow the flow; and two studs configured to: couple the compressor and the diaphragm together, attach to the diaphragm to provide attachment points on the diaphragm on each side of the weir portion, and respond to the closing or opening force so the attachment points on both sides of the weir portion cause the diaphragm to make sealing contact with the weir portion or cause the sealing contact to be released.Type: ApplicationFiled: July 20, 2012Publication date: January 23, 2014Applicant: ITT MANUFACTURING ENTERPRISES LLCInventor: Louis E.
