| 20100288036 | DEVICE FOR DETERMINING THE POSITION OF A PISTON IN A CYLINDER - A device for determining the position of a piston in a cylinder comprises an ultrasound facility for transmitting ultrasound signals into the inside of the cylinder and for receiving ultrasound signals that are reflected from said piston. A projection is provided on a front surface of the piston and comprises a front surface that is offset by a certain height with respect to the remaining front surface of the piston. The projection is isolated in any piston position that can be reached during operation. The position of the piston is determined by an analytical facility based on the transit time of the ultrasound signals between the ultrasound facility and the front surface of the projection. | 11-18-2010 |
| 20100124680 | FUEL CELL SYSTEM OPERATED WITH LIQUID GAS - A fuel cell system comprises at least one fuel cell with a high-temperature polymer electrolyte membrane. The fuel cell is supplied with liquefied petroleum gas from a supply of liquefied petroleum gas. The liquefied petroleum gas can be directly fed into an anode reaction chamber of the fuel cell without complex reforming. Water vapor is admixed to the liquefied petroleum gas before it enters the anode reaction chamber. | 05-20-2010 |
| 20090205419 | Ultrasonic Measuring Device for a Container - The invention relates to an ultrasound measuring device for a container. A coupling device supporting an ultrasound transducer serves for coupling and asymmetric alignment of the ultrasound transducer with respect to the container. This causes a sound field of the interfering signal in an ultrasound measurement to propagate within the container in an asymmetric fashion with respect to planes of symmetry of the container, whereby the interfering signal that is received at the site of injection is attenuated relative to a useful signal. | 08-20-2009 |
| 20080314072 | Air-Conditioning Unit for Mobile Devices - An air-conditioning device includes a refrigeration cycle having components such as, e.g., a compressor for compressing a refrigerant, a condenser and an evaporator. At least some of the components of the refrigeration cycle are held in their functional position by a mounting in the form of housing shells, which they share. The housing shells consists of a foamed plastic material, e.g. of expanded polypropylene (EPP). An additional metal sheet or plastic housing is not required. | 12-25-2008 |
