Abstract: A gauge is provided that is useful in measuring the horizontal wheelbase of a railway freight car truck sideframe. The gauge itself is comprised of a main horizontal body section usually of a single piece of aluminum bar stock. A stationary depending leg extends downwardly and is affixed to near one end of the main horizontal body section. A bearing slide assembly is affixed to the main horizontal body section near its other end. A measuring leg depends from the bearing slide assembly and is movable along the bearing slide assembly. An indicator scale is associated with the measuring leg so that its relative position with regard to the main horizontal body can be readily measured from a scale affixed thereon. The stationary depending leg is brought into contact with one edge of a pedestal jaw of the railway freight car sideframe, and the measuring leg is moved into contact along the bearing slide assembly with an opposite edge of the opposite pedestal jaw. A measurement reading of the wheelbase of a sideframe is then made.

Title: Method allowing cyclic pacing with average rate just above the intrinsic rate
Inventor: MOWER MORTON M
IPC: A61N1/362
Filed: 1999-05-21
Granted: 2004-05-04
Abstract: Method and apparatus for cyclic ventricular pacing starting at a rate just above the intrinsic atrial firing rate (overdrive pacing), followed by relaxation to a rate just below the intrinsic atrial firing rate (ventricular escape). The method and apparatus can be applied to one or both ventricles, and can utilize one or more electrodes per ventricle . The electrode(s) can be applied to inner or outer ventricular surfaces. Relaxation protocols as a function of time can be linear, curvilinear to include exponential, or mixtures thereof. Furthermore, relaxation protocols can include one or more periods of time during which th e pacing rate is held constant. Typically, the average ventricular pacing rate using this invention will be slightly greater than the intrinsic atrial firing rate, though alternate embodiments that encompass average ventricular pacing rates that are equal to or slightly less than the intrinsic atrial firing rate are also envisioned. Application of this method and apparatus to a heart in need thereof will produce a heart with an optimally minimized energy output requirement.

Title: Tissue modulation process for quantitative noninvasive in vivo spectroscopic analysis of tissues
Inventor: PETERSON CHARLES M
IPC: G01N21/64
Filed: 1999-07-07
Granted: 2009-01-27
Abstract: Methods are provided for noninvasively measuring blood volume and analyte concentration and for obtaining spectroscopic information relating to immobile tissues, such as skin. One method is for determining concentration of an analyte, such as glucose, in blood of a subject. The method comprises irradiating a region of tissue, such as a fingertip, of the subject with a light source; collecting fluorescence spectra by the region of tissue, the quantity of fluorescence spectra being indicative of blood volume; and collecting Raman spectra emitted by the region of tissue at a wavelength range that corresponds to the analyte. The method further comprises dividing the collected Raman spectra by the collected fluorescence spectra to obtain a number proportiona l to the concentration of analyte per unit blood volume. The method can further comprise determining the integral of net collected spectra, net collected spectra being a difference between spectra collected while the region of tissue is in a blood-replete state and spectra collected while the region of tissue is in a blood-depleted state. The method can further comprise enhancing the spectra collected by performing adjacent averaging smoothing operations. Blood volume in a region of tissue for spectroscopic measurement can be modulated by applying an ultrasonic transducer to the region of tissue, and also by applying a tourniquet.

Abstract: The present invention provides a projection system for the display of images in a wide range of ambient light conditions. The system comprises a system control component, two or more projectors and a screen unit. The system control component synchronises two or more images for projection by the projectors, with the image synchronisation enabling the generation of a coherent single image from multiple projected images. There are two or more projectors which project separate images and each projector projects an image onto a unique area of a screen unit. The synchronisation of the projectors is also controlled by the system control component. The screen unit has one or more screens for receiving the projected images and these screens are compatible with a rear projection system. The screens incorporate a contrast enhancing component which improves the resistance of the projected image to contrast degradation due to a wide range of ambient light conditions.
