| 20110121925 | SWITCHING DEVICE FOR A VEHICLE HAVING AN ELECTRONIC IMMOBILIZER AND METHOD FOR ACTIVATING AN ELECTRONIC IMMOBILIZER - A switching device for a vehicle having an electronic immobilizer includes at least one part which is fixedly mounted in relation to the vehicle and at least one sensing device which can move relative to the fixedly mounted part. The switching device further includes at least one induction coil which is provided for communication with a transponder that is integrated into a portable device. The induction coil is at least partially integrated into the movable sensing device. | 05-26-2011 |
| 20110148569 | METHOD FOR GAP CHARACTERIZATION IN INDUCTIVELY COUPLED ACCESS SYSTEMS - An access facility for a vehicle has a first transmit/receive device for transmitting a first radio signal and for receiving a second radio signal, a second transmit/receive device for transmitting the second radio signal and receiving the first radio signal, a transmission strength determining device for determining a transmission strength value, which represents the transmission field strength of the first radio signal transmitted by the first transmit/receive device, and a reception strength determining device for determining a second reception strength value, which represents the reception field strength of the first radio signal at the location of the second transmit/receive device. The information content of the first radio signal has the transmission strength value, and the access facility features a relation determining device for determining a relation between the transmission strength value and the reception strength value. | 06-23-2011 |

| 20090102102 | PROCESS FOR THE PRODUCTION OF HOLLOW BODIES OF THERMOPLASTIC MATERIAL BY EXTRUSION BLOW MOLDING - The invention concerns a process for the production of hollow bodies of thermoplastic material by extrusion blow molding. In the process according to the invention continuous extrusion of at least two preforms in web form of plasticized material is effected by means of a plurality of extrusion devices. The preforms are jointly shaped to form a hollow body in the still plastic condition, that is to say in the first heat, within a multi-part tool forming a mold cavity. In that case a wall thickness profile is imparted to at least one preform during the extrusion operation independently of the respective other preform by continuous nozzle gap adjustment during the extrusion operation. | 04-23-2009 |
| 20110129560 | Nozzle For The Production Of Hollow Bodies Of Thermoplastic Material By Extrusion Blow Molding - The invention concerns a nozzle for the production of hollow bodies of thermoplastic material by extrusion blow molding. According to the invention, continuous extrusion of at least two preforms in web form of plasticized material is effected by means of a plurality of extrusion devices. The preforms are jointly shaped to form a hollow body in the still plastic condition, that is to say, in the first heat, within a multi-part tool forming a mold cavity.
