Abstract: A stroboscope module has a coupling with which the stroboscope module can be connected to a light connection of an endoscope. The coupling comprises a sleeve and a base, with the base being arranged in the sleeve displacable in an axial direction between a first position and a second position. An elastically deformable cuff having an internal diameter is arranged within the sleeve, into which cuff the light connection of the endoscope can be inserted in the first position. The sleeve and the base compress the cuff in the second position such that the internal diameter of the cuff is reduced and the light connection of the endoscope is locked in the coupling. The sleeve and the base can be locked in the second position.

The invention also relates to a device for a moving shaft comprising such an encoder and to the method of manufacturing the encoder.

Abstract: A video endoscope comprises an elongate shaft having a longitudinal axis, and a handpiece at the proximal end of the shaft, a distal end of the shaft being provided with a lens and, in the proximal direction from the lens, with an electronic image pickup. The image pickup is connected, via an electrical connection extending along the shaft, to an electrical connector piece arranged on the handpiece. The image pickup and the connector piece can rotate relative to each other about the longitudinal axis of the shaft. The electrical connection comprises at least one flexible, elongate circuit board, which is able to twist about its longitudinal direction and has at least one conductor track.

Abstract: A method for estimating satellite-satellite single difference biases is described. The method uses an ionosphere-free mixed code-carrier combination of maximum ambiguities discrimination defined at the ration between wavelength and noise standard deviation. The accuracy of the biases estimation is further improved by an additional ionosphere-free mixed code-carrier combination of time-difference measurement that is uncorrelated with the first combination. Finally, an alternative method is based on a combination of carrier signals in a common frequency band which allows estimating the biases individually.

Abstract: An image pick-up module comprises an electronic image sensor, single-piece circuit board electrically bonded to the image sensor, and at least one cable electrically bonded and leading away from the circuit board. The circuit board has at least three sections, first and second section extending in relation to the other and obliquely or crosswise to the image sensor, and third section arranged between first and second section. The image sensor is arranged on the circuit board opposite the third section. In a method for assembling the image pick-up module, the circuit board has the form of a planar board blank comprising at least three sections folded along flexible connecting sections whereby the at least one cable is bonded to the board, and the board folds whereby a third section is located between first and second section, and the image sensor is bonded to the circuit board opposite the third section.

Abstract: A power-driven hand tool comprises a drive spindle adapted to drive a tool, that can be driven to oscillate about its longitudinal axis, which tool can be fixed on a retaining section of the dive spindle by a securing element, and further comprises a displacing device that serves to displace the securing element between a releasing position in which the securing element can be released from the drive spindle and a clamping position in which the securing element is clamped on the retaining section by a spring element, the securing element comprising a clamping shaft adapted to be inserted into the securing element, which is axially fixed in the drive spindle for clamping the tool in the clamping position, and which can be detached in the releasing position. For clamping of the tool a split chuck is provided which is clamped on the retaining section by the securing element in the clamped position and is connected with the retaining section in form-locking engagement.
