Abstract: An operating element for ophthalmological devices, in the form of a joystick in which existing, designated functions can be blocked and/or enabled in a targeted manner. The operating unit is in the form of a joystick and is provided for moving and/or controlling ophthalmological devices. According to the invention, at least one element is present for blocking a designated function and is designed such that the blocked function is enabled by removal of the element. For this purpose, the operating unit, designed as a joystick, has at the upper end an actuation unit with a press and/or rotate function. Although the present operating element is intended for ophthalmological devices, it can in principle also be used for joysticks that are employed in other technical fields, in order to change their functionality.

Abstract: An optoelectronic semiconductor device is disclosed wherein the device is a vertical-cavity surface-emitting laser or a photodiode containing a section, the top part of which is electrically isolated from the rest of the device. The electric isolation can be realized by etching a set of holes and selective oxidation of AlGaAs layer or layers such that the oxide forms a continuous layer or layers everywhere beneath the top surface of this section. Alternatively, a device can be grown epitaxially on a semi-insulating substrate, and a round trench around a section of the device can be etched down to the semi-insulating substrate thus isolating this section electrically from the rest of the device. Then if top contact pads are deposited on top of the electrically isolated section, the pads have a low capacitance, and a pad capacitance below two hundred femto-Farads, and the total capacitance of the device below three hundred femto-Farads can be reached.

Abstract: The arrangement has at least two electrooptic transducers (1, 2) with in each case one optically active zone (1a, 2a). Optical connections (12, 14) which are assigned to the transducers are adjacent at a spacing (a). Optical coupling paths (8, 9) run via a coupling device (6) between the connections (12, 14) and the respectively assigned optically active zones (1a, 2a) In order in the case of a very tight spacing (a) to permit a favorable crosstalk response and a cost effective design, the coupling paths (8, 9) run in such a way that the spacing (A) between two optically active zones (1a, 2a) is greater than the spacing (a).

Abstract: An extraction apparatus for heart pacemaker electrodes or defibrillator electrodes has an anchoring part which can be deformed using an actuating device from a displacement configuration into an expanded locking configuration. The anchoring part has a tube section with several wall cut-outs, which are offset in the axial direction and between which guide rings remain, which are connected by trough-shaped cross members. By exerting a tensile force on a control wire using the actuating device, the tube section is compressed and the trough-shaped cross members are deformed radially, so that they attain engagement with the inner lumen of the spiral helix of a heart pacemaker electrode cable or defibrillator electrode cable and, as a result of a spiral offset, bring about a positive locking, which permits high pull-out forces.
