Abstract: A method of calibrating multi-crystal, single block radiation detectors for use in positron emission tomography and other devices with multi-crystal, single block radiation detectors that are used to determine gamma ray distribution. The detector units are individually subjected to a gamma ray flood source wherein the gamma ray has an energy in excess of about 0.7 MeV, and preferably above about 1.0 MeV. Energies of up to about 10 MeV are usable with the calibration method, with higher energies giving rise to containment and handling problems because of the energy. The light produced within each of the crystals is converted to electrical signals through, for example, photomultiplier tubes. These signals are used to generate a lookup map, this map providing information as to the correct positioning and response of each crystal in the array of crystals of the block detector. The method is useful for detector blocks of of many sizes that are divided into arrays of a large number of crystals.

Abstract: A system for indicating the level of a liquid in a container is operable with either an analog type liquid level sensor producing an output signal which varies linearly in magnitude with the level of liquid, or a digital liquid level sensor producing a cyclic pulse width modulated signal which varies in duration according to the liquid level. One or the other type sensor is connected to an analog wire and a microprocessor is programmed to detect positive and negative going edges of pulses on the wire and generate values representing the duration of the pulses. If pulse edges are detected, the microprocessor uses the generated values representing the duration of the pulses to access a conversion table and obtain a multi-bit value for energizing the display. If no pulse edges are detected, the magnitude of the signal on the analog wire is converted to an equivalent digital value which is applied to a second conversion table to derive a multi-bit value for energizing the display.

Abstract: In this booster, the voltage across the terminals of the photovoltaic power source (1) is regulated as a function of a reference voltage (V.sub.ref) which is chosen to be substantially equal to the voltage corresponding to the maximum value of the voltage-power curve of this source. The reference voltage generated in the reference generator (9) is compared to the voltage (V.sub.sc) of the source (1), the result is sampled and influences the duty cycle of a control signal (F.sub.c) applied to the switching transistor (7). The latter is responsible for chopping the current flowing from the source to the load (accumulator 6) through an inductor coil (4) and a diode (5).
