20080272389 | Infrared Source - A sealed infrared radiation source includes an emitter membrane stimulated by an electrical current conducted through the membrane, which acts like an electrical conductor, wherein the membrane is mounted between first and second housing parts, at least one being transparent in the IR range, each housing part defining a cavity between the membrane and the respective housing part of each side of the membrane. The housing parts are at least partially electrical conductive, and a first of the housing parts is electrically coupled to a first end of the electrical conductor and insulated from the second end of the electrical conductor, the second housing part being electrically coupled to a second end of the electrical conductor and being insulated from the first end of the electrical conductor, thus allowing a current applied from the first housing part to the second housing part to pass through and heat the membrane. | 11-06-2008 |

20110149409 | POLYMER LENS - The invention relates to an optical element having adjustable focal length, and a method for producing an optical element. The optical element comprising a first transparent layer and a transparent soft polymer having a chosen refractive index situated thereon, said layer being made from a material having a chosen flexibility, e.g. a thin glass layer, the optical element also being provided with an actuator for applying a force upon said flexible layer, said force being essentially symmetric relative to said axis thus bending the layer providing a lens surface and providing a curved refractive surface. | 06-23-2011 |
20120074509 | WAFER BOND CMUT ARRAY WITH CONDUCTIVE VIAS - A wafer bonded CMUT array comprising a plurality of CMUT elements distributed across a substrates, each element comprising a cavity and a signal electrode formed in the substrate, and a conductive membrane closing the cavity and forming a ground electrode, wherein the membranes of the individual elements form an unbroken ground plane across the surface of the array and wherein electrical connection to the signal electrodes is provided by means of a conductive vias depending therefrom through the substrate from the signal electrode to the rear of the substrate. | 03-29-2012 |
20120162664 | ACTUATOR FOR MOVING A MICRO MECHANICAL ELEMENT - The present invention relates to an actuator for moving a rigid element, e.g. an optical element such as mirror ( | 06-28-2012 |
20120243095 | CONFIGURABLE MICROMECHANICAL DIFFRACTIVE ELEMENT WITH ANTI STICTION BUMPS - The invention relates to a micromechanical unit, in particular, an adjustable optical filter, and also a method to manufacture the unit. The unit comprises a first device layer and a second substrate layer at least partially fastened to each other, where the device layer comprises a number of reflecting elements divided between a number of non movable, fixed reflecting elements, where the fixed elements are connected with the substrate, and where a cavity is defined between the substrate and each movable element and each movable element is set up to produce a spring-loaded movement into the cavity, and where a number of dielectric spacer blocks are placed in the cavities between each movable element and the substrate to avoid electric contact between them. | 09-27-2012 |

20130179418 | SEARCH RANKING FEATURES - Search ranking features are described that may be used by a search engine to rank items in a search result. Examples of such features include use of multiple linear ranking stages, use of BM25 and a full text index, use of a minimum span on ranking stages, pre-calculation of a plurality of ranking models, use of a dynamic rank, use of more than one BM25 definition per stage, date/time transformations, freshness transformations, raw value transformations, query property rank, social distance, and so on. | 07-11-2013 |
20140074810 | MANAGING A SEARCH INDEX - Concepts and technologies are described herein for managing a search index. In accordance with the concepts and technologies disclosed herein, a search index can be hosted by a number of search nodes. The search engine can be configured to determine if a search node is unavailable, and if so, if data stored at the unavailable search node is to be replaced. If data stored at the unavailable search node is to be replaced, the search engine can identify sources for data to be used to replace the data at the unavailable search node. The search engine can issue instructions to the sources and/or the unavailable search node to copy the data from the sources to the unavailable node and/or to replace the data at the unavailable node with the data from the sources. Portions of the data can be copied from each of the sources to the unavailable node. | 03-13-2014 |
20140074811 | QUERY RANKING MODELS - Concepts and technologies are described herein for query ranking models. In accordance with the concepts and technologies disclosed herein, a search engine can be configured to expose a query ranking model object corresponding to a ranking function used by the search engine. A query application can be configured to obtain the query ranking model object and generate a query ranking model based upon the query ranking model object. The query ranking model can include one or more features and respective weights. The query application can generate a query and include data with the query identifying the query ranking model that is to be used to rank search results generated by the search engine. The query application also can be configured to manage query ranking models to allow creation, modification, and/or deletion of query ranking models as well as weights of features of the query ranking models. | 03-13-2014 |
