Abstract: A system and method for dialog state tracking employ an ontology in which a set of values are indexed by slot. A segment of a dialog is processed to detect mentions. Candidate slot values are extracted from the ontology, based on the detected mentions. The candidate slot values are ranked. A dialog state is updated, based on the ranking of the candidate slot values, which may be conditioned on the output of a temporal model, which predicts whether the value of the slot has been instantiated, modified, or is unchanged.

Abstract: A method for entity recognition employs document-level entity tags which correspond to mentions appearing in the document, without specifying their locations. A named entity recognition model is trained on features extracted from text samples tagged with document-level entity tags. A text document to be labeled is received, the text document being tagged with at least one document-level entity tag. A document-specific gazetteer is generated, based on the at least one document-level entity tag. The gazetteer includes a set of entries, one entry for each of a set of entity names. For a text sequence of the document, features for tokens of the text sequence are extracted. The features include document-specific features for tokens matching at least a part of the entity name of one of the gazetteer entries. Entity labels are predicted for the tokens in the text sequence with the named entity recognition model, based on the extracted features.

Abstract: A focal plane array (FPA) of infrared (IR) radiation detectors (20), such as an array of microbolometers, includes an active area (20A) containing a plurality of IR radiation detectors, a readout integrated circuit (ROIC) (12) that is mechanically and electrically coupled to the active area and, disposed on the ROIC, a plurality of heater elements (30A) that are located and operated so as to provide a substantially uniform thermal distribution across at least the active area. The FPA further includes a plurality of temperature sensors (30B), individual ones of which are spatially associated with one of the heater elements for sensing the temperature in the vicinity of the associated heater element for providing closed loop operation of the associated heater element.

Abstract: A microbolometer detector element (10) for a focal plane array is provided including an optically absorptive material structure (12) characterized by an electrical resistivity that varies as a function of its temperature coupled in spaced relation to a thermal isolation structure (20). The thermal isolation structure (20) is coupled in spaced relation to a sensor (34) connected to the optically absorptive material structure (12) for sensing the absorptive structure's (12) electrical resistivity. The thermal isolation structure (20) facilitates very high fill factors even when the pixel size is shrunk below the baseline fifty micron size. The thickness of the optically absorptive material structure (12) and the thermal isolation structure (20) can be independently controlled since the thermal isolation structure (20) is disposed in spaced relation under the absorptive material structure (12).

Abstract: An array of photodetectors is constructed of IR radiation-responsive Group II-VI alloy semiconductor material, such as HgCdTe. A novel photodetector structure utilizes internal reflections from mesa (10, 10') sidewalls and/or from reflective material (22) that is applied to the mesa sidewalls to achieve a concentration of incident infrared radiation into a significantly smaller radiation absorbing region (16). The resulting self-focusing or light piping effect enables the leakage current and other noise-generating processes to be minimized, while providing an effective large optical collection area. The fabrication of specular, flat, sloped mesa sidewalls is preferably accomplished by a reactive ion etch process. Signal crosstalk between photodetectors is reduced or eliminated since the radiation absorbing regions are fully delineated and isolated from one another by deep trenches that define the mesa sidewalls.

Abstract: An integrated photovoltaic detector includes a reference photovoltaic detector and an active photovoltaic detector in a series connection. The reference detector produces a dark current that opposes the active detector's dark current. The active detector effectively masks the reference detector from incident illumination so that the active detector produces photocurrent but the reference detector does not. The band gap of the reference detector is preferably matched to the active detector so that their dark currents are substantially matched over a temperature range. As a result, the current read out of the integrated detector at the series connection is approximately equal to the photocurrent generated by the active detector. This improves the detector's SNR, signal resolution, and useful operating temperature range.

Abstract: A method for fabricating a plurality of semiconductor photodetectors and an array of same produced by the method. The method includes a first step of selectively removing semiconductor material to form a channel within a semiconductor material for physically isolating a first photodetector from a second photodetector, the semiconductor material having a characteristic energy bandgap. The method includes a second step of selectively increasing the carrier concentration of the semiconductor material within a bottom region of the channel for preventing minority charge carriers from diffusing under the channel from a region associated with the first photodetector to a region associated with the second photodetector. The step of selectively removing is accomplished by the steps of providing a patterned mask upon the semiconductor material and selectively removing the underlying semiconductor material through an opening within the mask.
