Patent number: 6288512Abstract: A robot has a plurality of components which can pivot relative to each other, in particular robot arms. Changes in separation between individual points of the robot thereby occur. This must be taken into consideration when guiding the operation cables for robot elements and in particular robot tools. The cables must be capable of accommodating length changes while being loaded to as little extent as possible during motion of the robot so that they have high durability and are not prematurely damaged. In accordance with the invention, a robot having cables extending at least partially on the outside, in particular operation cables for robot tools such as a welding tool, has cables guided in a substantially circular loop at the height of a robot arm which can pivot about an axis of the robot.Type: GrantFiled: April 15, 1999Date of Patent: September 11, 2001Assignee: Kuka Roboter GmbHInventors: Alwin Berninger, Georg Hartmann

Patent number: 6244506Abstract: A description is given of a method of extending the period of validity of smart cards, without the cards having to be surrendered by their owner. For this purpose, use is made of reading/writing devices which are installed near smart card users and, by extension passwords sent to the owner by a central issuing agency, extend the date of validity of the smart card.Type: GrantFiled: July 26, 1996Date of Patent: June 12, 2001Assignee: Bayer AktiengesellschaftInventors: Georg Hartmann, Gunnar Weikert, Patrick Horster

Patent number: 6082622Abstract: A system and method of storing and preparing data uses at least one data memory card having at least one electronic memory chip and a separate optical memory. At frequent intervals alphanumeric data is entered into the at least one electronic memory chip. At less frequent intervals, image data is entered into the optical memory, data is read from the at least one electronic memory chip and data is transferred from the at least one electronic memory chip into the optical memory.Type: GrantFiled: November 27, 1996Date of Patent: July 4, 2000Assignee: Bayer AktiengesellschaftInventors: Georg Hartmann, Gunnar Weikert

Patent number: 4705243Abstract: To supply the implement, mostly a welding tool, of a manipulator (1), with energy, the invention, instead of running the supply lines in the known manner from a fixed point in a large, freely suspended loop directly to the tool, provides an external suspension of a line bundle (10) along the constructional assemblies of the manipulator. In accordance with the invention, this line bundle (10) is held in place and guided in tubular casings (13) which are disposed at the individual assemblies (3-5) of the manipulator (1), with inserts (19) being provided in these casings (13) for receiving and holding lines of unequal size (parallel with each other) which are adapted to the various functions of the manipulator and can quickly be exchanged.Type: GrantFiled: June 10, 1985Date of Patent: November 10, 1987Assignees: KUKA Schweissanlangen, Roboter GmbHInventors: Georg Hartmann, Kurt Wiedemann, Ernst Zimmer

Patent number: 4133511Abstract: In the disclosed system a motor axially displaces a screw-threaded movable valve member by rotating it within an interiorly threaded collar. A sensor detects the movable valve member's axial position. An electrical feed-back circuit compares the sensor output with a reference value and drives the motor accordingly. In one embodiment the motor possesses a disc rotor and in another embodiment a moving coil rotor. In each case the stator links the rotor conductors which extend radially from the rotor center.Type: GrantFiled: January 26, 1977Date of Patent: January 9, 1979Assignee: Frieseke & Hoepfner GmbHInventors: Georg Hartmann, Adam Dittner, Karl Prenzel

Patent number: 4025934Abstract: A method and device is disclosed whereby the number of revolutions of an axle or the angle of rotation of an axle are represented by a particular value. The value is preferably in the form of an electric analog signal. A pickoff element having a linearly-shaped primary coil and a linearly-shaped secondary coil is disposed so that the primary and secondary coils are in parallel with an air gap therebetween. The air gap is for the formation of a homogeneous stray field. A metallic disc which has a rim in the form of an Archimedes' spiral, is affixed to an axle. The disc is disposed in the air gap between the primary and secondary coils. A high frequency signal is supplied to the primary coil. Accordingly, when the axis is rotated, an amplitude modulated signal is developed at the secondary coil. The amplitude modulated signal is then demodulated and subsequently differentiated to provide an analog signal proportional to the angular rotation of the axle or the number of revolutions of the axle.Type: GrantFiled: April 29, 1976Date of Patent: May 24, 1977Assignee: Frieseke & Hopfner GmbH Erlangen-BruckInventors: Georg Hartmann, Adam Dittner
