| 20130334398 | MOTION AND SIMPLE GESTURE DETECTION USING MULTIPLE PHOTODETECTOR SEGMENTS - An optoelectronics apparatus selectively drives a light source, and includes four electrically isolated photodetector (PD) segments that detect light that has reflected off an object. Each of the four PD segments produces a corresponding signal, referred to as signals A, B, C and D, indicative of the light detected by the respective PD segment. Circuitry is used to produce a first motion signal indicative of a sum of the signals A plus B minus a sum of the signals C plus D, i.e., the first motion signal is indicative of (A+B)−(C+D). Further circuitry produces a second motion signal indicative of (B+C)−(A+D). Additional circuitry produces a signal and/or data that is indicative of a direction and/or rate of motion of an object, in dependence on the first and second motion signals. | 12-19-2013 |
| 20140145069 | PACKAGED LIGHT DETECTOR SEMICONDUCTOR DEVICES WITH NON-IMAGING OPTICS FOR AMBIENT LIGHT AND/OR OPTICAL PROXMITY SENSING, METHODS FOR MANUFACTURING THE SAME, AND SYSTEMS INCLUDING THE SAME - Packaged light detector semiconductor devices (PLDSDs), methods for manufacturing PLDSDs, and systems including a PLDSD are described herein. In an embodiment, a PLDSD includes a light detector die having a surface including an active photosensor region, and a non-imaging optical concentrator including an entrance aperture and an exit aperture axially aligned with one another and with the active photosensor region. A molding material forms the non-imaging optical concentrator and encapsulates at least a portion of the surface of the light detector die that extends beyond the exit aperture of the non-imaging optical concentrator. The non-imaging optical concentrator concentrates light from the entrance aperture toward the exit aperture and onto the active photosensor region. In certain embodiments, a reflective material is disposed on an inner surface of the non-imaging optical concentrator, and a light transmissive molding material fills at least a portion of an inner volume of the non-imaging optical concentrator. | 05-29-2014 |

| 20080222261 | SYSTEM AND METHOD OF SUPPORTING CONSTRUCTIVE DISCOURSE ON COMPUTERS AND MOBILE DEVICES - A system and method to allow a user to engage in a collaborative discourse embedded in messaging platforms such as email or instant messaging, and to visualize the structure of that discourse. The system provides the ability to create and modify tree-like structures, which can represent outlines or tables of contents employed in documents. These structures take the place of traditional documents in representing the work product of a knowledge worker. These structures are related to the discourse in that messages may refer to nodes of these structures, and hence be understood to be related. It is the interplay between the creation of a structured message-based discourse and the persistent outline-form knowledge structures that allows message-based correspondence, including the reading and writing of documents, to be performed with increased efficiency and at a higher level of integration. | 09-11-2008 |
| 20090171625 | Statement-Based Computing System - A computer-implemented system and method creates and stores measurement statement objects representing complete statements of measurement. Each measurement statement object represents a measurement, such as “the left wing of the F-16 aircraft has a span of 36 m,” and contains a value object, an aspect object, and an entity object. The value object represents a value of the measurement (such as 36 meters) and the aspect object represents an aspect of the measurement (such as span). The value is a value of the aspect of the measurement. The entity object represents an entity (such as the left wing of an F-16 aircraft) measured by the measurement. The aspect of the measurement is an aspect of the entity measured by the measurement M | 07-02-2009 |
