Abstract: A glucose measuring device for determining the concentration of glucose in intravascular blood within a body part of a subject. The device includes at least one light source having a wavelength of 650, 880, 940 or 1300 nm to illuminate the fluid. At least one receptor (14) associated with the light source (12) for receiving light and generating a transmission signal representing the light transmitted is also provided. A support piece is including for supporting the light source associated with the respective receptor. The support piece is adapted to engage a body part of a subject. Finally, a signal analyzer determines the glucose concentration in the blood of the subject. A method for determining the glucose concentration is also provided which calibrates a measuring device and sets the operating current for illuminating the light sources during operation of the device.

Abstract: A personal manually portable thermoelectric-cooling medicine kit, particularly for insulin, is provided. The medicine in the kit is cooled by a Peltier heat pump. The vials of medicine inside the kit are tilted to maximize heat transfer efficiency when the kit is either upright or laid flat. A cap is provided to shield an insulin vial from UV radiation while the case is open and the person is preparing for an injection. The kit includes components which are Velcro-attached to the lining of the kit.

Abstract: A color recognition system which illuminates a test surface through the use of a source light and fiber optic cables. The light transmitted to the test surface is reflected into a light pipe and then transmitted through fiber optic cables to a first plurality of color filtered photo detectors. The photo detectors produce quantitative color component values for the tested surface. Light is also transmitted directly from the source light through fiber optic cables to a second plurality of color filtered photo detectors. The second plurality of photo detectors produce quantitative color component values for the light source. The values produced from the first plurality of photo detectors are then adjusted with respect to the values produced from the second plurality of photo detectors.

Abstract: A machine vision analysis apparatus and method for automatically checking objects for specified characteristics. A video camera is provided for producing an analog video input signal corresponding to an area having an object therein being observed by the video camera. A video timer and synchronizer is used for coordinating synchronous operation of the machine vision apparatus. A digital-to-analog converter is also provided for converting a digital threshold gray level into an analog threshold level corresponding to said digital threshold level, wherein an upper and a lower threshold level are produced. A comparator is used for digitizing the analog video input signal into a digitized video signal based on the analog threshold gray levels, wherein the video input gray level must fall between the lower threshold gray level and the upper threshold gray level for a pixel to be digitized into an ON state.

Abstract: A pap smear inspection apparatus and method for automated screening of cytological smears for dense, possibly malignant cells includes a specimen slide for receiving a cytological smear and a microscope for enlarging the image of the smear. The microscope is outfitted to receive a video camera for creating an analog video signal corresponding to an area enlarged by the microscope and being observed by the video camea. A video timer synchronizes operation of the smear analysis apparatus. An image window generator focuses the analysis of the apparatus on a sub-area of the entire video image. A converter is provided for converting a digital threshold level into a corresponding analog threshold level. A comparator is used for transforming the analog video input signal into a binary video signal according to the analog threshold levels. A pixel counter sums the number of ON pixels both in the transformed video signal, and within the designated window sub-area of said video signal.

Abstract: A radial mandrel is provided having a plurality of alternating and interfitting large and small segments mounted on a pair of cones, which cones are movable axially toward and away from one another to in turn move the segments radially inwardly and outwardly between a contracted and expanded position. The radial mandrel includes an improved mechanism for axially moving the cones comprising a quill adapter and scroll sleeve adapted for use with a drive shaft of standard configuration. The scroll sleeve is formed with spiral grooves which engage the cones and are operable to move the cones axially toward and away from one another as the scroll sleeve is rotated.
