A method and a device for automatically releasing a ski boot from a ski on which the boot is mounted, in the event of danger to the skier. The forces acting in a skier's leg are continuously monitored and are compared, over a predetermined interval of time, with a threshold value. When the forces reach a predetermined value, related to the threshold value, the ski boot is released from the ski.

Process and apparatus for providing digital data indicative of the contour of a leaf-like article, e.g. a tobacco leaf, and the flaws (holes) that it may comprise, from a video signal composed of image lines. The video signal is coded by comparing same with thresholds so as to detect transitions. The number n of points pertaining to a hole is compared with a threshold n1, firstly within a line X, ...

A circuit is disclosed for fault-monitoring a microprocessor. The circuit includes an oscillator having an output signal of the same frequency as a test signal output of the microprocessor. The circuit also includes a binary counter. The microprocessor test output is coupled to the reset input of the counter and the oscillator is coupled to the counting input of the counter. The counter counts whe...

An animal drinking bowl with a bowl dish surrounded by a rear wall and two side walls and a cover wall supported by the rear wall and the side walls is to be improved in such a manner that a smaller width of the bowl results and that the bowl has no parts which are easy to break off or knock off. This aim is achieved in particular in that the side walls are drawn in, preferably in the manner of a ...

A ski fastener structure has a rigid bar element removably fixable to a ski and engaging the lower end of a rod element pivotable about a horizontal axis substantially perpendicular to the ski longitudinal axis. The rod element is effective to resiliently encircle a rear region of the skier's leg at the middle area of the tibia and the skier's footwear is removably connected to the bar element.

A device for engaging and holding a sole of a ski boot, which device includes a sole holder which is adjustable in a vertical direction relative to the ski by means of an adjusting screw and is connected to a ski binding part which is associated therewith. The adjusting screw is secured to the ski binding part and is prevented from lifting off in a vertical direction from the ski while at the same...
