Abstract: A solid-state device for the non-invasive generation and capture of thermal gradient spectra from sample tissue. The device includes an infrared transmissive layered window assembly, a means for inducing a thermal gradient in sample tissues. Also provided is an infrared radiation detector for detecting infrared emissions emanating from the tissue as the transient temperature gradient progresses into the sample tissues. The sensor provides output signals proportional to the detected infrared emissions. A data capture means is provided for the sampling of output signals received from the infrared radiation detector as the induced temperature gradient progresses into the sample tissue.

Abstract: A solid-state spectrometer for the non-invasive generation and capture of thermal gradient spectra from human or animal tissue. The spectrometer includes an infrared transmissive thermal mass window for inducing a transient temperature gradient in the tissue by means of conductive heat transfer with the tissue, and cooling means in operative combination with the thermal mass window for cooling the thermal mass window. Also provided is an infrared sensor means for detecting infrared emissions emanating from the tissue as the transient temperature gradient progresses into the tissue, and for providing output signals proportional to the detected infrared emissions. Data capture means is provided for sampling the output signals received from the infrared sensor means as the transient temperature gradient progresses into the tissue.

Abstract: A calibration standard for calibrating a thermal gradient spectrometer. The calibration standard is a structure having a particular glucose concentration which a thermal gradient spectrometer reads for determining whether the spectrometer is in calibration. The structure of the calibration standard properly mimics the physiology of human tissue. A number of such standards, each containing a different concentration of glucose are provided in kit form with a thermal gradient spectrometer for use in calibrating the spectrometer. The spectrometer is provided with a display and internal circuitry for performing self-calibrating adjustments and a communications port for electronically coupling to a remote computer and database for supplying external calibration commands to said spectrometer.

Abstract: A drier for wafers or the like has a drier chamber shaped to receive the wafer, which is lowered into the open top of the drier chamber and withdrawn therefrom by a lifter, which may be motor actuated. Below the drier chamber is a heater chamber to vaporize alcohol or other liquid, which rises and condenses on the relatively cool wafer. A water jacket around the top of the drier chamber condenses vapor and thus reduces escape of vapor.

Abstract: A wafer retention arrangement is disclosed for use with wafer stripping machines and the like which include a housing and a turret rotatably coupled to the housing for rotation about a selected axis, the turret being formed with a plurality of pockets that are adapted to retain a wafer. The wafer retention arrangement for each pocket includes a plurality of clips disposed about the periphery of the pocket to support a retained wafer. A latching mechanism cooperates with the support means to hold the wafer within the pocket. The latching mechanism is pivotally mounted to the turret for rotation about an axis that is substantially parallel to the surface of a wafer held within its associated pocket. The pivot point about which the latch mechanism rotates is substantially adjacent the edge of the wafer but spaced apart from the wafer plane.
