Abstract: An electronic device back-up charger 70 comprises a housing 72 provided with a pivoting head portion 74 having an electrical connector 76 mounted thereon for connecting the charger 70 to a electronic device, as well as a battery 78 provided within the housing 72. The battery 78 is electrically coupled to the connector 76 wherein, in use, the connector 76 can be pivoted to the desired angle and connected to a electronic device for temporarily recharging the phone from the battery 78.

Abstract: The invention relates to a detector cell comprising tunnel-effect superconductive devices organized in a two-dimensional array and placed on a common substrate, each superconductive device comprising a tunnel-effect superconductive junction and being electrically connected to a bottom connection area and to a top connection area. The superconductive devices are separated from one another by trenches extending down to and including the bottom connection area and defining individual bottom connection areas disposed between each of said junctions and the substrate. At least one individual bottom connection area is electrically connected to at least one bottom connection area of an adjacent superconductive device by a localized bridge region.

Abstract: The present invention relates mainly to a detection cell, a matrix detector using such cells, a sensor including such a detector, and a spectroscope including such a sensor. The invention provides a photon detection cell comprising a superconducting element, in particular of niobium, that is sensitive to photons of the radiation to be detected or to phonons generated by such photons, in particular by breaking Cooper pairs into quasi-particles and by means of a superconducting tunnel junction including a superconducting electrode, the cell being delimited by a plurality of spaced-apart superconducting tunnel junctions that are distributed around the periphery of the cell. The device of the invention is applicable to counting photons, and thus mainly to acquiring and processing information coming from faint radiation sources.
