Patent number: 7319478Abstract: A solid-state video camera is equipped with pixel addition logic such that, if the measured object brightness falls below a certain threshold value, a brightening of the image is effected without increasing the noise component accepting a loss in real-time representation. The pixel addition by way of the pixel addition logic is coupled to the gain control of the camera in a manner such that, in each case, the gain control compensates for jumps in brightness which arise by way of the pixel addition and creates for the user a flowing transition without noticeable jumps in brightness.Type: GrantFiled: April 4, 2003Date of Patent: January 15, 2008Assignee: Richard Wolf GmbHInventors: Martin Dolt, Michael Vögele

Patent number: 6970620Abstract: In the region of a distal end at its circumference the waveguide is formed transparent to the radiation which impinges onto the surface of the waveguide at suitable angles, and in the region of the distal end in the inside of the waveguide there are arranged scatter elements which scatter radiation transmitted by the waveguide in the direction of the distal end in a direction with a proximally directed component which exits the circumference of the waveguide. Alternatively, radiation entering into the waveguide at the circumference of the waveguide in a direction with a distally directed component is transmitted by the waveguide in the direction of the proximal end, as well as to its use and to a method for its manufacture.Type: GrantFiled: April 3, 2003Date of Patent: November 29, 2005Assignee: Richard Wolf GmbHInventors: Lars Ziegenhagen, Gereon Hüttmann

Patent number: 6947091Abstract: A focussing and focal length adjusting device for an optical lens system in the camera head of an endoscope. This device includes a focussing device which has several piezoelectric bending actuators attached along and symmetrically to the optical axis of the focussing lens. The piezoelectric bending actuators are via in each case one joint member connected to a sleeve encompassing the focussing lens in a manner such that with voltage impingement bending movements carried out by the bending actuators are converted into a linear focussing movement for the focussing lens. Furthermore a zoom drive adjusting the focal length of a zoom lens system includes a stepper motor whose stepped rotation via a grooved roller and a pin linearly moved by the helical groove of this roller is converted into a linear movement of a zoom lens sleeve for the focal length adjustment.Type: GrantFiled: June 15, 2000Date of Patent: September 20, 2005Assignee: Richard Wolf GmbHInventors: Holger Widmann, Michael Voegele, Ulrich Osterland

Patent number: 6918916Abstract: The target apparatus for positioning a drilling tool with respect to a drilling channel to be created in a bone consists of a target hook and a guide arm which is releasably connected to this and on which there is arranged a receiver for the drilling tool, and a guide path in the form of a laterally through-going open groove for the guide arm. The guide arm may be displaced and fixed in the guide path. A simple assembly and disassembly of the apparatus is achieved in that the guide arm on the side of the apparatus is applied into the guide path through the groove opening and reversely, by lifting away out of the groove, may be separated from the target hook.Type: GrantFiled: September 20, 2002Date of Patent: July 19, 2005Assignee: Richard Wolf GmbHInventors: Jürgen Göbel, Eberhard Körner, Helmut Heckele
