Abstract: Some implementations provide low power reduced sampling of global positioning system (GPS) locations. A server may be configured to assist a mobile device in determining a location from a plurality of GPS signal samples and corresponding time stamps provided by the mobile device, such as by identifying a set of possible reference locations, which may be used to calculate a location of the mobile device. In another example, the mobile device may sample GPS signals using a GPS receiver, compress the samples, and provide the compressed samples to the server for processing.

Abstract: Some implementations provide low power reduced sampling of global positioning system (GPS) locations. A server may be configured to assist a mobile device in determining a location from a plurality of small GPS signal chunks and corresponding time stamps. For instance, the server may identify a set of satellites from each of the GPS signal chunks and by comparing the set of satellites for each of the GPS signal chunks to each other to determine a second set of satellites. The server may then estimate a location of the mobile based on the second set of satellites.

Abstract: The effective use of weak GPS signals that are present in various environments enables an electronic device to pinpoint its location in such environments. The electronic device uses an antenna to perform sequential scanning in multiple directions for global positioning system (GPS) signals. The electronic device further analyzes GPS signals obtained from scanning the multiple directions to determine a number of acquired GPS satellites that provided the GPS signals. The GPS signals include code phases of the acquired GPS satellites. The electronic device then computes a location of the electronic device based on the code phases of the acquired GPS satellites when the number of acquired GPS satellites meets a threshold.

Abstract: A semiconductor light emitting diode chip relates to the field of production technologies of a light emitting diode. In the present invention, corresponding graphical current extension layers are respectively disposed below an N pad and a P pad, and in all light emitting compound areas, there is electronic compound light emitting. Compared with the prior art, an area of a light emitting compound area is increased, which can effectively improve current distribution and light emitting brightness of a chip. In addition, graphical current extension can effectively increase an adhesion of a pad on a surface and improve the reliability of a chip.

Abstract: Various technologies described herein pertain to disambiguation of a mention of an ambiguous entity in a document. A set of candidate entities can be retrieved from an entity knowledge base based upon the mention of the ambiguous entity, where each of the candidate entities has a respective entity feature representation. Moreover, a document feature representation can be generated based upon features of the document and the respective entity feature representations of the candidate entities. A processor can be caused to select a subset of features from the document feature representation based upon a measure of how discriminative the features from the document feature representation are for disambiguating the mention of the ambiguous entity. A disambiguated result for the mention of the ambiguous entity can be determined based upon the subset of the features. The disambiguated result can be an unknown entity or one of the candidate entities.

Abstract: The present invention provides a semiconductor light emitting diode (LED) device and a formation method thereof. The device comprises: an active layer; a P-type semiconductor layer and an N-type semiconductor layer respectively located at two sides of the active layer; a positive electrode welding layer electrically connected to the P-type semiconductor layer; and a negative electrode welding layer electrically connected to the N-type semiconductor layer. The material of the positive electrode welding layer and/or the negative electrode welding layer is an aluminum alloy material. The present invention is capable of better meeting requirements of the LED device for the electrode welding layers, improving electro-migration resistance under large current, and improving the thermal stability of the device. Compared with a conventional aluminum material, the service life of the device is increased, and control over industrialization cost is facilitated.
