    摘要: A device for measuring relative viscosity includes a fluid reservoir, a stirrer, and a sensing system. The stirrer has two members, with one member being more bendable than the other. When the stirrer is moving, the sensing system detects a differential bend between the members; the differential bend is related to the viscosity of a fluid in the fluid reservoir. The sensing system includes two spaced sensors which detect when magnets on the members pass the sensors. A timer provides a time lapsed between passage of one of the members past a sensor and passage of the other member past the other sensor. The time lapsed is related to the viscosity of the fluid in the fluid reservoir. A controller automatically controls the addition of a solvent to the fluid within the fluid reservoir; the addition of the solvent is dependent on the time lapsed.

    摘要: A railway traffic control system in which accurate vehicle information is effectively available in real-time to facilitate control of traffic flow. Unlike prior art methods of precisely monitoring train location, the current invention is dependant only on equipment on-board the vehicle and position updates provided by external benchmarks located along the track route. The system's dynamic motion capabilities can also be used to sense and store track rail signatures, as a function of rail distance, which can be routinely analyzed to assist in determining rail and road-bed conditions for preventative maintenance purposes. In presently preferred embodiments, the on-board vehicle information detection equipment comprises an inertial measurement unit providing dynamic vehicle motion information to a position processor. Depending on the amount and quality of apriori knowledge of the vehicle route, the inertial measurement unit may have as many as three gyroscopes and three accelerometers or as little as a single accelerometer. To minimize error between benchmarks, the processor preferably includes a recursire estimation filter to combine the apriori route information with movement attributes derived from the inertial measurement unit.

    摘要: Apparatus for soldering and desoldering an electronic component to or from a printed circuit board includes an alignment station and a soldering/desoldering station. The printed circuit board is mounted upon an adjusable X-Y table which can be indexed between the alignment station and the soldering/desoldering station. To align an electronic component with respect to th PCB, a vacuum pickup device is operated at the alignment station to pickup and support the component within an optical field of view above the PCB and the X-Y table is adjusted in X, Y and .theta. directions with respect to the component. Upon alignment of the component, the pickup device is lowered to temporarily adhere the component to the PCB by an adhesive flux. Thereafter, the X-Y table is indexed to a preset position below a hot air soldering nozzle and the component soldered in a known manner. A rotary device for shearing a defective electronic device from a PCB is also attached to the bottom of the soldering/desoldering nozzle.

    摘要: An avalanche photodiode (APD) electro-magnetic radiation (EMR) detector for visible to near infrared wavelengths is described. The detector includes an EMR absorption region, a voltage biasing element, and a charge multiplication region. The EMR absorption region includes a substantially regular array of silver or aluminum nanoparticles embedded in a matrix material. The voltage biasing element is configured to apply a bias voltage to the matrix material such that electrical current is directly generated in the EMR absorption region based on a cooperative plasmon effect in the detector material when electro-magnetic radiation in the visible to near infrared wavelength range is incident upon the detector material, where the dominant mechanism for decay in the cooperative plasmon effect is non-radiative. The charge multiplication region is arranged relative to the EMR absorption region to avalanche multiply the electrical current generated in the EMR absorption region.
