Title: Interchangeable hitch ball having plunger with j-shaped channel
Inventor: LINDENMAN THOMAS W
IPC: B60D1/52
Filed: 2002-04-02
Abstract: A hitch ball assembly includes a towing ball having a mounting aperture and an annular race in communication with the mounting aperture.      A post includes a base, an axial bore and a plurality of openings in communication with the axial bore. A ball bearing is received in each of these openings.

IPC: H04B10/2507
Filed: 2002-05-23
Abstract: An optical beam path directing system has a field-flattening optically transmissive wedge installed in spatially dispersed beam paths upstream of the planar surface of a micro electro-mechanical switch (MEMS) or liquid crystal array. The parameters of the field-flattening wedge and its location in the diffracted beam paths are defined such that the wedge effectively rotates a 'best fit' planar surface approximation of the curvilinear focal plane of a concave reflector into coplanar coincidence with the optical signal-receiving surface of the MEMS. As a result, loss variation is essentially flat and minimized across the optical signal transmission band.

Abstract: A method and apparatus (100) for providing continuous analysis and display of the variability of multiple patient parameters monitored by multiple bedside monitors (106a-106c) for each patient (102). Each monitor is connected to a patient interface and to a patient data storage unit (115) and a processor (113). Each monitored patient parameter is measured in real-time. Data artifacts are removed, and variability analysis is performed based upon a selected period of observation. Variability analysis yields variability of the patient parameters, which represents a degree to which the patient parameters fluctuate over time, to provide diagnostic information particularly useful in the detection, prevention and treatment of multiple organ dysfunction syndrome (MODS).

Abstract: A support structure flange preform (11) resembles the Greek letter "pi" and has a base (13) with two legs (15, 17) extending therefrom. The perform is composed of a composite material that is formed from tows of woven or braided fiber. The tows are oriented to extend throughout each the base and legs. The perform may be either impregnated with a suitable thermoset resin, or may be unimpregnated so that resin may be infused at a later step of the overall manufacturing process. Two of the preforms are joined to a sine wave-shaped web (31) of the structural beam. The web is formed from uncured, thermoset resin sheets that are reinforced with oriented fibers. The web has two outer laminates that sandwich a syntactic or foamed resin layer in between. The legs of each perform straddle one edge of the web and are shaped to both sides to the precise contours of the web. A laminate strip (33) is positioned against the base of each preform to create a pair of flanges for the structural support member. The assembled structure is then heated and cured. The web and/or flanges of the structure also may be configured with alternating beads, tapered in either the vertical or horizontal direction, or inclined at non-orthogonal angles.

IPC: G01N33/48
Filed: 2001-12-11
Abstract: A method of imaging a histological sample is provided which comprises stimulating autofluorescence in a sample using electromagnetic radiation of wavelength 750nm. Detection of the autofluorescence is undertaken by a CCD camera, typically with an excitation filter of 510nm disposed between the camera and the sample. The weak signal from autofluorescence is reinforced by manipulation of data acquired by the camera. Autofluorescence is detected from an upper face of the sample, an upper layer of the sample removed and a next face of the sample imaged. These steps are repeated to obtain information on autofluorescence throughout the sample. The method enables detection of features for virtually any thickness of slice, and in particular slices can range from 50.mu.m to 1.mu.m, with the method generally being used to analyse slices of thickness 5-1.mu.m. There is also provided a method of preparing a histological sample for use in the above method, and apparatus (10) for imaging autofluorescence in histological samples.
