Abstract: An electronic device (10) provides user message notifications as to messages that were received when the user was not in possession of or in the vicinity of the electronic device. The electronic device includes a communications circuit (46) for receiving an incoming message, and an output device (30, 32, 50) for outputting a message notification associated with the incoming message. A sensor (20) detects a user and generates a detection signal when the user is detected. A controller (41, 42) is configured to receive the detection signal, and configured in response to the detection signal to generate the message notification for outputting by the output device. In one embodiment, a timer (36) counts a predetermined time after receipt of the incoming message. If a user input is not received within the predetermined time, the controller causes the electronic device to enter an away from phone (AFP) mode in which the sensor is activated.

Abstract: A laser system generates read, green and blue beams from a single laser beam generated by an IR continuous-wave laser using rare-earth or transition elements. Semiconductor diodes are used to excite IR continuous-wave laser and simple passive non-linear frequency conversion is used to generate the red, green and blue effective beams.

Abstract: A micromechanical structure with cavities, containers, openings, canals, depressions, humps or the like for examinations of sample substances for possible changes of physical and/or chemical properties with targeted evaluation and documentation for the purposes of biotechnology, gene technology, cell and immune research and other medical, agricultural and environment research, where the structure consists of semiconducting material (of the group III to V of the elements of the periodic system) or contain the latter or glass or ceramic, diamond, or carbon and is made by a masking technique, especially by a chemical etching technique.

Abstract: A semiconductor device for converting light into electric energy comprises at least one layer of amorphous silicon with a surface thereof which is intended to be exposed to light covered by a cover layer of polycrystalline silicon. The use of the polycrystalline silicon increases the current yield in the blue light range of the solar spectrum. A method of producing such a semiconductor device is also disclosed.

Abstract: An infrared detector element of the Schottky-barrier type is constructed to have its sensitivity in the range of about 8 to 12 microns. For this purpose a silicon substrate (1) has a highly doped surface layer (3) of p.sup.+ -silicon with a doping density in the range of 5.times.10.sup.18 to 5.times.10.sup.19 (atoms per cm.sup.3) and a thickness in the range of 50 to 200 Angstroms. On top of this layer (3) a metal layer (2) for example of platinum is deposited and partially alloyed into layer (3) to form PtSi. Such elements are arranged in arrays and may be combined with other detector elements having their sensitivity in other spectrum ranges, e.g., 3 to 5 microns and/or in the visible spectrum range.

Abstract: A method and device for manufacturing semiconductor elements of amorphous licon which convert light into electrical energy comprising, supplying a silicon compound to a vessel, passing an electric field through the vessel sufficient to produce a glow discharge having free electrons in the vessel to precipitate amorphous silicon from the silicon compound onto a substrate in the vessel, and providing a magnetic field in the vessel which is directed substantially transversely to the electric field and is of a magnitude sufficient to conduct the free electrons along closed paths over the surface of the substrate.

Abstract: A fungicide mixture for combatting stem-breaking diseases and spike or ear diseases in cereals and corn, comprising from 50 to 90 percent by weight of N-(1,1,2,2-tetrachloroethylthio)-3a,4,7,7a-tetrahydrophthalimide and from 50 to 10 percent by weight of 2-(4'-thiazolyl)-benzimidazole, based on the total weight of the two components.

Abstract: An internal combustion engine has at least three cylinders and induction conduits opening into the lower portion of the cylinders or into the crankcase. The induction conduits are intended at least for combustion air, comprising at least one rotary disc valve rotatably driven by the crankshaft of the engine. The valve has the form of a disc whose rotation axis crosses or intersects the crankshaft of the engine and is arranged in a valve housing through which the induction conduits extend, said valve being designed to alternately open and close the passages of the induction conduits through the valve housing. Said valve housing has at least three induction conduit inlets and is driven at an rpm which is lower than the crankshaft rpm and has a number of sets of recesses corresponding to the rpm reduction for control of the induction.
