摘要:
The invention concerns a method and device for generating electrical energy for operating small electrical appliances, such as remote-controls, pocket calculators, electric strikes, etc. According to the invention, at least some of the electrical energy necessary for operating the small electrical appliance is obtained from the energy used for manual operation of the function-triggering element (34). The voltage source in the device according to the invention comprises a mechanical/electrical transformer (generator) (10') supplied with kinetic energy by the manual actuation of the function-triggering element (34).

The invention concerns a method and a device for continuous adjustment of control values of an electrical appliance by means of a remote control (1), for example, an audio or video remote control. The electrical energy required for adjusting the control values is produced by an electrical generator (13) located in the remote control (1). After a start command to adjust a control value has been emitted, the remote control electronics system switches into an essentially zero-current state until a subsequent stop command is emitted which terminates the automatically advancing adjustment of the control value. Emission of said stop command is carried out using a break contact which does not close until the actuated key (4) is released.

Ein Rohling zur Herstellung von künstlichen Zahnteilen, wie z.B. Inlays, Overlays, teilweisen oder vollständigen Kronen und Brücken umfasst einen Körper aus Verbundmaterial. Der Körper besteht aus Laminatschichten (A) grosser Kauabrasionsfestigkeit, gefolgt von Laminatschichten (B) grosser Bruchfestigkeit und Laminatschichten (C) geringerer Härte bzw. Festigkeit. Der Rohling wird mittels Materialabtragung so zu einem Zahnteil geformt, dass der Bereich der festen Laminatschichten eine verstärkende Tragstruktur bildet. Mittels Formschleifen kann aus einem solchen Rohling in einem Bearbeitungsschritt eine dauerhafte Rekonstruktion hergestellt werden.

A scanner system digitizes 35mm transparencies or negatives, and converts the image to a format compatible with popular microcomputer systems. This scanner system can accommodate various formats, and has variable zoom, pan and window size. Color separation is accomplished by an illumination arrangement causing rapid sequential generation of red, green and blue components. A low wattage light source is used, and color balance is achieved by adjusting the respective exposure times of the three primary colors. The system has internal calibration to achieve repeatable color balance. The system implements a wide variety of color coding schemes ranging in resolution from 1 to 24 bits. An adaptive process compresses the data in order to optimize the color selection process. The illumination optics are anamorphotic for high efficiency. Mechanical and electrical interfaces are compatible with a conventional 5-1/4" floppy disk drive standard.

A method and apparatus to convert absolute angular or linear position to digital information utilizes a single track. Multiple sensors are placed at essentially equal intervals along a track, especially a single track. The output from the group of sensors is converted to natural binary format by combinatorial logic. The sensors may be of different types, for example maybe mechanical contacts, optical, magnetic/inductive, or capacitive transducers, and may distinguish two or more levels each. Such an encoder can be used as a potentiometer, multiposition switch, shaft encoder, or as length measurement device. The code is of the Gray-code kind, in other words adjacent positional readings have a Hamming distance of one.
