Abstract: A low-voltage alternating current-based LED light with built-in cooling and automatic or manual dimming. As it is self-cooled with fan failure protection, the light can be safely run in conditions that are near-hostile to its operation, with little possibility of damage. The light is movable along the XY axes of a grid system and can be either fixed in position in the Z axis or can be movable up and down the Z axis. The light can be equipped with either manual dimming using a standard potentiometer, or with automatic dimming via sensors and local network connectivity. The device prevents line-voltage electric shocks as the input voltage is low-voltage AC; in embodiments, about the same voltage as a doorbell, and the input current is 3 A. The device is also self-cooled, and will shut down if its fan is not running so as to prevent thermal overloads.

Abstract: A method of reducing variation in optical power levels across a group of light emitting diodes includes testing each respective one of the light emitting diodes to determine an optical power level produced by that light emitting diode when connected to an electrical power source. During testing, the electrical power source delivers a substantially identical amount of electrical current to each respective one of the light emitting diodes. The optical power levels from the test all fall within a first range of values. The method includes connecting an electrical resistance in parallel with at least some of the light emitting diodes to reduce an amount of optical power produced by those light emitting diodes. After the electrical resistances are connected, all of the optical power levels produced by the light emitting diodes fall within a second range that is narrower than the first range.

Abstract: A monitoring system for adjusting a light source for a counting cell signal in a counting and dispensing system, which light deteriorates over time as a result of dust accumulation from the handling of pills, capsules, and tablets. The monitoring system uses electronics to adjust the light relative to the dust accumulation, thus maintaining an accurate counting cell signal, so that the system can continue to function. In this respect, the monitoring system provides for longer intervals between required maintenance operations, and therefore reduces the cost of operation.

Abstract: A method and apparatus for checking the calibration of analyzers employing radiant energy is disclosed. The invention embodies changing the radiant energy source color temperature by a precise increment and adjusting the span to reflect the predetermined amount of differential absorbance between reference and analytical interference filters which would result from said increment of change in source color temperature. The invention is particularly useful when employing radiant energy in the ultraviolet, visible and infrared spectra. The invention eliminates the need for standard liquid or gaseous calibration solutions or special optical calibration filters.

Abstract: Phase and amplitude balance adjustment are provided for a gas analyzer of the type in which two infrared beams are generated, one passed through a cell containing a standard and the other through a cell containing a sample gas, constituents in which are to be detected and measured; and there is a detector which compares the energy absorption in the two cells to provide a measure of the gas content. In this type of gas detector there is a chopper consisting of a rotating shutter with two sectors which rotate in front of two apertures through which infrared beams are transmitted from two different infrared beam generators. Phase adjustment is accomplished mechanically by physically moving a mounting plate carrying the two infrared beam generators with respect to the position of the apertures. Amplitude balance adjustment is accomplished by adjusting the relative electrical energy supplied to the two infrared beam generators.

Abstract: Before traversing the area in which conditions are to be measured, a portion of a modulated luminous measuring beam is branched off and directed to a photoelectric detector. A portion of a modulated luminous comparison beam also is branched off and sent to the detector. The strengths of the beams received by the detector are compared and used to control the intensity of one or both of the beam sources in a manner such that the ratio of intensities of the two sources is constant.
