Abstract: Various systems and methods for temperature measurement are disclosed. For example, some embodiments of the present invention provide methods for temperature measurement that include exciting a provided transistor with at least four sequential input signals of different magnitudes. In response, the transistor exhibits a sequence of output signals corresponding to the four sequential input signals. The sequence of output signals is sensed using a different gain for each of the output signals included in the sequence of output signals, and the output signals included in the sequence of output signals are combined such that the combined output signals eliminates a resistance error. The combined output signals are then used to calculate a temperature of the transistor.

Abstract: A device for use as a magnifying implement is disclosed which has a housing member designed to accommodate prescription bottles of various popular sizes therein in a fixed position. A longitudinally moveable magnifying lens slideably mounted in the housing member is utilized to magnify the print contained on an instruction label located on the side of the prescription bottle. Alternate embodiments allow different size medicine bottles to be alternately mounted in concentric fashion, or with the side of the medicine bottles facing the lens in a fixed position.

Abstract: The system relates to a telescope having optics and a scanning head which images a two-dimensional field of view point by point onto a localized thermal sensor. An aperture stop is mounted within the telescope housing and at least part of it is within the field of view of the sensor. The temperature of the stop is controlled by means of Peltier thermo-electric modules so that it corresponds to the average temperature of the external field of view. This prevents halation or blooming which would result from extreme temperature contrasts. The vignetting which occurs when the aperture stop is within the field of view gives an increased magnification for a given size of objective optics, and the benefits outweigh the corresponding reduction in thermal sensitivity.

Abstract: A magnifying indicator for a thermometer or similar columnar instrument, said indicator consisting of a one-piece body of transparent plastic formed with a cylindrical base block and an upstanding lens on the front portion of the base block. Opposite the lens the base block is formed with a rearwardly-facing vertical V-groove in which the columnar instrument is receivable. A U-shaped wire spring is anchored at one side of the groove and transversely overlies the groove. The spring is arranged to allow the columnar instrument to be slipped into the groove so as to engage against the flat sides thereof and thereafter to clamp the instrument in the groove to prevent angular disorientation of the lens relative to the columnar instrument, while permitting sliding adjustment of the magnifying indicator along the instrument scale.
