Patent number: 8120511Abstract: A device for continuous measurement of the forces acting upon a movable compressible playable object is provided with at least one transmitter communicating with at least one receiver outside the movable object. The at least one receiver transforms signals received and evaluates them online. The movable compressible playable object, for instance a ball, includes at least one pressure sensor and/or at least one three-dimensional acceleration sensor as well as a converter for transforming signals therefrom to transmit them to the transmitter. A method for the use of this device causes activation of the transmitter in the movable object so that a system is created for the measurement of the forces acting upon such an object wherein the received measuring signals are present in evaluated form, online or offline, to be analyzed. By means of the activation method, the active sensor system is initiated to receive and transmit measuring signals.Type: GrantFiled: September 1, 2006Date of Patent: February 21, 2012Assignee: Fraunhofer-Gesellschaft zur Förderung der Angewandten Forschung E.V.Inventors: Herbert Reichl, Jurgen Wolf, Klaus Lang

Patent number: 6772738Abstract: An injection system for internal combustion engines is proposed, in which once the engine has been turned off, a pressure equalization is established between the intake side and the pressure side of the high-pressure fuel pump. This prevents uncombusted fuel from reaching the combustion chambers of the engine. The pressure prevailing on the pressure side and the intake side when the engine is off furthermore assures that vapor bubbles cannot form, and this makes starting the engine easier.Type: GrantFiled: September 9, 2002Date of Patent: August 10, 2004Assignee: Robert Bosch GmbHInventors: Helmut Rembold, Klaus Joos, Jens Wolber, Thomas Frenz, Markus Amler, Hansjoerg Bochum, Hans-Peter Harnisch, Peter Ropertz, Klaus Lang, Wolfgang Saatmann
