Patent number: 7884313Abstract: A sensor arrangement includes at least one transparent elevation, which is formed on the surface. The transparent elevation is made of a first transparent material. At least one first facet of the transparent elevation defines a first angle with the surface. This first angle is larger than an angle at which a total-reflection occurs at an interface of the first transparent material and air and is at the same time smaller than an angle at which a total reflection occurs at an interface of the first transparent material and the liquid. A light source is arranged for emitting an incident ray into a first direction passing through the surface into the transparent elevation such that in a presence of a liquid at the first facet, an incident ray is transmitted through the first facet. In an absence of a liquid, the incident ray is reflected due to a total reflection at the facets. A light detector is provided for detecting the reflected ray.Type: GrantFiled: June 28, 2005Date of Patent: February 8, 2011Assignee: Robert Bosch GmbHInventor: Matthieu Richard

Publication number: 20110029211Abstract: A mechanism for reducing brake noise during braking of a vehicle. The mechanism includes controllers and methods that “hold” a currently applied braking torque rather than applying the operator-requested braking torque when a vehicle is traveling at a low speed and the operator-requested braking torque is within a predetermined range. The controllers and methods “release” the previously “held” braking torque and apply the operator-requested braking torque once the operator-requested braking torque is outside the predetermined range.Type: ApplicationFiled: August 3, 2009Publication date: February 3, 2011Applicant: Robert Bosch GmbHInventors: Arthur Stephenson, Jingsheng Yu, Shawn Berry, Ed Schultz

Patent number: 7878851Abstract: Known pumping devices have a connection lid, a connection cap slipped over the connection lid, a hollow chamber formed between the connection lid and the connection cap, and electrical connections that extend through the connection cap into the hollow chamber. It is disadvantageous that when fuels containing water are being pumped, such as ethanol, corrosion can occur at the electrical connections and at the uninsulated cable segments that are exposed to fuel near the electrical connections, for instance at the electrical coils or flexible cables of the carbon brushes, and in the final analysis this leads to an interruption in the electrical contact and thus to failure of the pumping device. In the electrical device of the invention, corrosion of the electrical connections and of the electrical components adjoining them upstream and downstream is avoided entirely or at least greatly diminished. According to the invention, the electrical connections are each provided in separate chambers of the hollow chamber.Type: GrantFiled: November 5, 2008Date of Patent: February 1, 2011Assignee: Robert Bosch GmbHInventors: Danilo Silva, Erich Jahrstofer, Eric Plantier, Jens Gringer, Peter Weber, Celso Eduardo Fávero, Philip De Haan, Reinhard Dittmann
