Patent number: 8667955Abstract: A handheld work apparatus has a drive motor which drives a work tool and a generator. The work apparatus has a first electrical load and a connectable second electrical load. The generator provides the electrical power for the simultaneous operation of the two loads. The work apparatus has a control unit for controlling the power supplied to the first electrical load. In order to supply approximately the same power independent of voltage fluctuations, a voltage monitoring circuit is provided which, in a first operating state, sets a first signal sequence for operating the first load and, in a second operating state, sets a different second signal sequence for operating the first load. The mean power of the first signal sequence and that of the other second signal sequence are approximately equal.Type: GrantFiled: April 20, 2012Date of Patent: March 11, 2014Assignee: Andreas Stihl AG & Co. KGInventors: Heinrich Leufen, Jörg Präger, David Fallscheer

Patent number: 8669493Abstract: In an electrically-heated glazing unit including a plurality of collector conductors configured to supply a plurality of heating conductors with an electric current used to heat up the heating conductors and the glazing unit, at least one partial region of the surface of the glazing unit includes an arrangement of parallel heating conductors in which the current flows in opposing directions. The arrangement of the heating conductors in the partial region of the surface is tuned to minimize by mutual compensation or eliminate the magnetic field acting locally within this partial region and perpendicularly to the plane of the glazing unit when the current flows. The operation of an apparatus sensitive to magnetic fields, for example a compass, in the immediate vicinity of the glazing unit thus becomes more reliable.Type: GrantFiled: December 21, 2007Date of Patent: March 11, 2014Assignee: Sanit-Gobain Glass FranceInventors: Marc Maurer, Stefan Ziegler, Martin Melcher

Patent number: 8668876Abstract: A configuration includes two exhaust gas treatment devices disposed in succession in an exhaust gas line. A first exhaust gas treatment device has a first subregion connected through at least one support body to a second subregion of a second exhaust gas treatment device. The support body has opposite ends connected by connections points to respective subregions. At least the second subregion is formed by metallic components that contact one another to form contact surfaces and at most 20% of the area of the contact surfaces have brazed or solder connections and/or diffusion connections.Type: GrantFiled: May 28, 2013Date of Patent: March 11, 2014Assignee: EMITEC Gesellschaft fuer Emissionstechnologie mbHInventors: Rolf Brück, Kait Althöfer

Patent number: 8669492Abstract: A passenger seat device includes a seat heater embedded in a seat and a detector electrode embedded underneath the seat heater. Electric power is supplied to the seat heater from an on-board battery through seat heater switches. Alternating voltage or current is supplied to the detector electrode. The detector electrode potential relative to the ground is lowered when the seat is occupied by a passenger. The changes in the potential of the detector electrode is detected by an occupant detector including a microcomputer. The detection is performed when the seat heater is brought to a floating state to suppress an amount of capacitance formed between the seat heater and the detector electrode. Thus, a sensitivity of the occupant detector is improved. The detector electrode may be eliminated, and the occupant conditions may be detected based on a potential of the seat heater to which alternating current or voltage is supplied.Type: GrantFiled: July 9, 2007Date of Patent: March 11, 2014Assignee: Denso CorporationInventors: Hiroyuki Ito, Tsutomu Kamizono, Shoichi Yamanaka

Patent number: 8662452Abstract: A structural article including an outer surface that serves as an aerodynamic surface when the structural article is subjected for an air stream. A resin matrix laminate includes an upper ply and a bottom ply. A heating element is arranged in contact with the bottom ply and coupled to a power supply unit in purpose to deice/anti-ice the outer surface. Each ply includes a thermally conductive filament structure having a filament orientation such that the prolongation of the filaments has an extension essentially perpendicular to the extension of the laminate. The thermally conductive filament structure of the upper ply is embedded in the upper ply in such way that at least a portion of the thermally conductive filament structure is exposed in the outer surface.Type: GrantFiled: January 14, 2010Date of Patent: March 4, 2014Assignee: SAAB ABInventors: Per Hallander, Mikael Petersson, Björn Weidmann, Tommy Grankäll, Göte Strindberg, Pontus Nordin
