    摘要： An apparatus calibrates a thermostatic control by adjusting a temperature selecting member to the sensed ambient temperature and then moving a settable shaft, which is frictionally engaged by the temperature selecting member, relative to the temperature selecting member, until operation of the thermostatic control is sensed. A detector is provided for detecting if the settable shaft is set between predetermined upper and lower limits. Also a moveable table is provided for conveying thermostatic controls into a calibration station in the calibration apparatus.

    摘要： A system and tuning method to collaboratively calibrate high voltage DAC values and Photomultiplier Tube DAC values of photomultiplier tubes of a gamma camera so that the detector produces a valid energy spectrum over the entire detector surface. A method for tuning a gamma camera having a plurality of photosensors, exposes the photosensors to scintillation photons corresponding to nuclear radiation of known energy; measures an energy output corresponding to each specific photosensor; calculates an average enemy output of all photosensors in the camera; collaboratively adjusts a DAC value corresponding to a voltage applied to a specific photosensor and a DACHV value corresponding to a high voltage applied to the camera based on the calculated average energy, energy output of each photosensor, and a target energy value corresponding to said known energy; and repeats the calibration until convergence is achieved between the average energy, energy output, and target energy.

    摘要： A method is presented for glide testing a disk which tests the glide head fly-height by inducing a collision between the glide head and a disk under test. The glide test system is initially calibrated using calibration disks. The method of the invention periodically tests the calibration without interrupting the production testing by lowering the rotation rate until the glide head collides with the rotating disk surface. The rotation rate at which the collision occurs is then compared with the value expected based on knowledge of disk samples and the initial calibration. Parameters for acceptable high and low values are established to detect changes in the glide test system performance to trigger automatic or manual recalibration.

    摘要： A black body assembly is provided for use in the calibration of infrared cameras. The assembly includes, among other things, a housing within which calibration components may be situated, and a lens guide for accurately positioning the assembly over a lens of the infrared camera. A heat emitter may be positioned within the housing for emitting a necessary amount of heat for calibration purposes. A heating element may also be provided within the housing for controlling the heating and cooling of the heat emitter. The assembly may also include a heat sink to remove excessive heat generated from the thermoelectric cooler during temperature cycling. An arm may be employed to hingedly connected to the assembly the camera to provide reliable and repeatable way to position the black body assembly at the front of the infrared lens. A method for calibrating an infrared camera is also provided.
