  • Auxiliary cooling device
    Patent number: 7856831
    Abstract: An auxiliary cooling device to be used in another cooling device, which auxiliary cooling device includes a thermoelectric element, such as a Peltier element, provided with a heat source and a heat sink connected in a circuit. The heat sink is used for directly or indirectly cooling an item, for example a bottle of fluid. The heat source, which is thermally isolated with respect to the heat sink, is in close thermal contact with a heat exchange fluid in a container. The heat exchange fluid is used as a thermal buffer for the waste heat generated by the cooling process.

  • Method for controlling the motion of a machine element
    Patent number: 4914363
    Abstract: To avoid variation between the resultant paths of multiaxis motions of a machine element for different override curves, distance-time curves of the axis motions are stored for an override value of 100%, and a relevant distance-time curve is subjected, in synchronism with a time sequence of selectively varied override values for each axis, to a time expansion which is inversely proportional to the respective override value.

  • Method for positioning a tool of a multi-joint robot
    Patent number: 4894788
    Abstract: A method for positioning a tool of a multi-joint robot is disclosed in which an incorrect positioning of the tool resulting from nonideal geometrical relationships is compensated by the following steps: determining a preliminary desired angular position for each of the joints for a desired position in space of the tool based upon the reference distances and joint axis directions required to position the tool in the desired position; determining the positioning error of the tool due to the differences between the reference distances and the desired directions and the actual spacings and actual directions of the joints; transforming the determined positioning error into corresponding angular correction values for the preliminary desired angular positions of the joints by means of an inverse Jacobi matrix coordinate-transformation equation system; calculating the error-corrected angular position for each of the joints by addition of the angular correction values to the preliminary desired angular positions; and
