Abstract: A non-destructive testing technique, particularly suitable for the non-invasive examination of human body tissue, wherein the object of interest is sequentially transilluminated with light having different wavelengths. Apparatus for practicing the technique alternately generates light of different colors and the light which passes through the tissue is detected by a video system synchronized with the source of the different wavelength light. The video system provides information bearing signals to data processing circuitry which determines the transmissivity at each wavelength of each point of the object within the viewing field.

Abstract: An ultrasound adapter is provided for a medical diagnostic device which implements a transillumination modality. The ultrasound adapter enables the sharing of data processing circuitry between the transillumination and ultrasound modalities. When in use, the ultrasound adapter provides image data at a rate and in a format which corresponds to that produced by the image sensor of the transillumination instrumentality.

Abstract: An electrostatic system monitor and method for monitoring the operation of static control equipment such as conductive workbench and floor mats, conductive wrist straps, and the integrity of ground connections and soldering irons and to activate indicators and alarms when the static control equipment deteriorates or malfunctions by having resistances outside of predetermined values and ranges of resistance. The electrostatic system monitor also provides for the detection of unsafe voltage potentials on soldering irons, and for a surface resistance probe for measuring the surface conductivity of conductive surfaces of the static control equipment.

Abstract: A non-destructive testing technique, particularly suitable for the non-invasive examination of human body tissue, wherein the object of interest is transilluminated with multi-wavelength light. Apparatus for practicing the technique generates transillumination light containing different colors and the light which passes through the tissue is divided and filtered to provide plural light beams lying in separate wavelength ranges. These light beams are detected by a video system which provides information bearing signals to data processing circuitry which determines the transmissivity at each wavelength of each point of the object within the viewing field.
