| 20080223435 | Micron gap thermal photovoltaic device and method of making the same - A method of making a micron gap thermal photovoltaic device wherein at least one standoff is formed on a photovoltaic substrate, a sacrificial layer is deposited on the photovoltaic substrate and about the standoff, an emitter is attached to the standoff and has a lower planar surface separated from the photovoltaic substrate by the sacrificial layer, and the sacrificial layer is removed to form a sub-micron gap between the photovoltaic substrate and the lower planar surface of the emitter. | 09-18-2008 |
| 20090277488 | Method and structure, using flexible membrane surfaces, for setting and/or maintaining a uniform micron/sub-micron gap separation between juxtaposed photosensitive and heat-supplying surfaces of photovoltaic chips and the like for the generation of electrical power - A near-field energy conversion structure and method of assembling the same, utilizing a sub-micrometer “near field” gap between juxtaposed photocell infrared radiation receiver and heat emitter surfaces, wherein compliant membrane structures, preferably fluid-filled, are interposed in the structure. | 11-12-2009 |
| 20100319749 | Sub-micrometer gap thermophotovoltaic structure (MTPV) and fabrication method therefor - An MTPV thermophotovoltaic chip comprising a photovoltaic cell substrate, micron/sub-micron gap-spaced from a juxtaposed heat or infrared radiation-emitting substrate, with a radiation-transparent intermediate window substrate preferably compliantly adhered to the photovoltaic cell substrate and bounding the gap space therewith. | 12-23-2010 |

| 20090250923 | Unit With At Least Two Hydraulic Connections Fastened To It - An electrohydraulic unit assembly for a motor vehicle comprising a receiving body defining a sealing face and at least two connectors fastened to the receiving body of the unit, oriented substantially parallel one to another and separated by a defined distance from one another. Each connector is configured for connecting a fluid conduit to the unit. Each connector includes a screw fitting for fastening the respective hydraulic connection to the receiving body of the unit such that a sealing face of the screw fitting or a sealing face of the fluid conduit is seated on the sealing face of the receiving body. Each screw fitting is rotatably connected to the body and includes two spanner flat portions having different spanner widths. | 10-08-2009 |
| 20090250998 | Electronic Control Unit With Cooling by Means of a Valve Block - Disclosed are hydraulic/electronic control units ( | 10-08-2009 |
| 20090295221 | Hydraulic Trailer Brake System - A trailer device for driving stabilization of vehicle combinations is provided. In order to design a device for driving stabilization of passenger vehicle trailers in a cost-effective and simple manner, a brake system for braking the trailer by an overrun brake and for stability regulation is designed so as to have separating valves, switching valves, inlet and outlet valves and a pressure build-up pump. A stabilizing coupling is also connected by means of a second pressure medium pump to actuators which can vary the clamping force of the stabilizing coupling between the trailer and tractor vehicle if the second pressure medium pump conveys pressure medium from the storage tank into or out of the actuators. | 12-03-2009 |
| 20100231033 | HYDRAULIC UNIT FOR SLIP-CONTROLLED BRAKING SYSTEMS - A hydraulic unit for slip-controlled braking systems has a plurality of receiving holes for transport devices associated with a plurality of hydraulic circuits bundled into groups, wherein the receiving holes are disposed at a distance from each in parallel with the upper side and a drive shaft having eccentrics located at the plane spacing for driving the transport devices. In order to provide a compromise optimized for manufacturing a small, convenient hydraulic unit, it is proposed that three theoretical planes (E | 09-16-2010 |

| 20100076996 | SYSTEM AND METHOD FOR AUDIO HOT SPOTTING - Audio hot spotting is accomplished by specifying query criterion to include a non-lexical audio cue. The non-lexical audio cue can be, e.g., speech rate, laughter, applause, vocal effort, speaker change or any combination thereof. The query criterion is retrieved from an audio portion of a file. A segment of the file containing the query criterion can be provided to a user. The duration of the provided segment can be specified by the user along with the files to be searched. A list of detections of the query criterion within the file can also be provided to the user. Searches can be refined by the query criterion additionally including a lexical audio-cue. A keyword index of topic terms contained in the file can also be provided to the user. | 03-25-2010 |
