Abstract: A power supply for small integrated circuit devices which utilize a nominal supply voltage of 1.5 V but which are energized by a long-life lithium-iodine battery having a terminal voltage of 2.8 V. The power supply reduces the voltage to the integrated circuit to the required 1.5 V and also provides a means for delivering current peaks to a device operated by the integrated circuit, such as a stepping motor or LED display, while maintaining a relatively constant supply voltage to the integrated circuit.

Abstract: This invention relates to a device for measuring the ultraviolet radiation in the UV-A and/or UV-B range with detector means for said ranges, switching means for considering the skin sensitivity, electronic means for evaluating the signals derived from the detector, means for displaying the intensity and/or the dose of the radiation and second switching means for selecting one of different quartz lamps in said ranges. This device is in particular adapted for digitally measuring the dose of harmful erythem effective UV-B radiation or the dose of therapeutic healing UV-A radiation. This invention further relates to a method for producing and calibrating said devices, in particular the shunts contained in said second switching means which enables to select different quartz lamps with different line intensities.

Abstract: This invention concerns an oscillator for time measurement, comprising a resonator the oscillation of which is maintained by at least one part reciprocated by electrostatic forces relative to at least one electrode connected to a direct voltage source, said part being periodically charged by contact with the electrode, or electrodes comprising an elastically deformable contact making member whose elastic deformation energy is much less when in contact with an electrode than the motional energy of the resonator.

Abstract: The present invention relates to a miniaturized nuclear battery, consisting of several in series connected cells, wherein each cell contains a support which acts as positive pole and which supports on one side a .beta.-emitter, above said emitter is a radiation resisting insulation layer which is covered by an absorption layer, above which is a collector layer, and wherein the in series connected cells are disposed in an airtight case.
