摘要： A system and method for determining the temporal resolution of a tomographic imaging device uses an apparatus to drive one or more dynamic phantoms composed of multiple materials. The apparatus is placed at or near the isocenter of the imaging device and the one or more phantoms are moved to produce a plurality of dynamic features, each having a specified frequency. The dynamic features are imaged with the device and the acquired image data corresponding to the dynamic features is analyzed to determine a temporal modulation transfer value at each of the known specified frequencies. The temporal resolution of the imaging device is determined using these temporal modulation transfer values.

摘要： A pressure measuring device includes a resilient expandable pressure sensor element having an open end and an opposite closed end. The pressure sensor element includes spiral flutes extending between the open and closed ends defining spiral bellows. The pressure sensor element is tapered over at least a portion of its length from the open end to the closed end. The pressure measuring device also includes a supporting structure having a pressure indicating scale. The supporting structure holds the pressure sensor element such that the open end of the pressure sensor element is in communication with a fluid whose pressure is to be measured and pressure applied by the fluid causes the pressure sensor element to expand axially and be visibly displaced relative to the pressure indicating scale by a distance related to the pressure applied by the fluid.

摘要： A pressure measuring device includes a partially coiled tube having a closed end and an opposite open end. The closed end is rolled and set into a coiled configuration. The device also includes a partially coiled tube supporting structure having a pressure indicating scale. The supporting structure holds the partially coiled tube such that the open end of the tube is in communication with a fluid whose pressure is to be measured. Pressure applied by the fluid causes the tube to unroll and the closed end of the tube to be visibly displaced relative to the pressure indicating scale by a distance related to the pressure applied by the fluid.

摘要： A syringe having an internal pressure gauge comprises a syringe barrel; a piston within the barrel; a spring coupled to the piston at a first position of the spring, the spring having a second portion that is movable in response to fluid pressure within a syringe cavity; and a pressure gauge having an indicator correlated to a plurality of positions of the second portion of the spring to indicate a pressure of a fluid. The spring can be a bellows. The first portion of the spring can be coupled to the piston to form a sliding seal with an inner wall of the syringe, and the second portion of the spring can move longitudinally within the syringe without sealing contact.

摘要： An instrument and method using electron spin resonance spectrometry for measuring the concentration of airborne soot particles, and the like, that includes continuously passing a sample of exhaust gas through a resonating RF microwave cavity resonator during the application therethrough of a uniform slowly varying uniform magnetic field that is rapidly modulated and measuring the resulting phase modulation or amplitude modulation thereof to derive an electron spin resonance signal that directly senses the concentration of carbon free radicals produced as a result of inefficient combustion of hydrocarbons during operation of the vehicle or boiler. A further invention is the use of this signal for feedback control of the engine or boiler operating parameters to minimize or substantially eliminate particulate matter emissions.
