Patent number: 8079439Abstract: The invention concerns a hydraulic steering with a steering initiator, a steering unit with feedback properties, which can be activated by the steering initiator, the steering unit having a supply connection arrangement with a pressure connection (P) and a tank connection (T) and a working connection arrangement with two working connections (L, R), an auxiliary-force operated steering valve, which is located in parallel with the steering unit between the supply connection arrangement (P, T) and the working connection arrangement (L, R), and a feedback suppressing device, which is active, when the steering valve is active. It is endeavored to find a simple manner of ensuring the priority of the steering initiator over the steering valve. For this purpose, the steering initiator interacts with an activation sensor, which deactivates the feedback suppressing device on an activation of the steering initiator.Type: GrantFiled: November 2, 2009Date of Patent: December 20, 2011Assignee: Sauer-Danfoss ApsInventors: Bendt Porskrog, Kjeld Buus Jensen, Finn Visgaard Nielsen, Svend Erik Thomsen

Patent number: 7797320Abstract: A solution is provided wherein the apparent dimensionality of a data set is reduced by ranking combinations of dimensions and parts of dimensions in terms of their suitability for mapping to the axes of a grid display. A user may then be presented with dense lower dimensional views of the data that are much easier to understand than sparse high dimensional views. The user may then make further refinements, groupings, and analyses as needed.Type: GrantFiled: March 15, 2005Date of Patent: September 14, 2010Assignee: Hyperion Solutions CorporationInventor: Erik Thomsen
