20100304952 | METHOD OF PROCESSING NEPHELINE SYENITE - A method of processing a useable particulated nepheline syenite including providing particulate nepheline syenite with a maximum first grain size; milling the nepheline syenite in a ball mill operated substantially dry to produce a dry feed stock with particles less than a given size; and, using an air classifier to remove particles having a second grain size from the feed stock to provide an Einlehner Abrasive Value of less than about 100. In practice the second grain size is less than 5 microns and the distribution profile is generally 4-5 microns. The product produced by the method is, thus, novel. | 12-02-2010 |

20120239335 | AUTOMATICALLY CONFIGURABLE SENSING DEVICE - The present document describes a ready to use sensing device which is auto-configurable when turned on. The sensing device includes one or more sensors and a communication port. When turned on, the system automatically contacts a central server via the communication port and requests the address of a second server with which the sensing device is associated. Upon receipt of the address of the second server, the sensing device contacts the second server and requests its customized configuration settings. When received, the configuration settings are installed, and the sensing device starts to sample the output of the sensors and sends the samples to the second server for storage. The user may view the measurement data by accessing the second server through the internet. The minimum memory capacity required for operating the sensing device is very low, due to the fact that the samples are sent to the second server every time the samples are taken. | 09-20-2012 |

20120144561 | FULLY INTEGRATED THREE-DIMENSIONAL TEXTILE ELECTRODES - There is described herein a knitting technique for creating a garment having one or more 3D textile electrodes integrated therein. The knitting technique involves knitting the item with integrated electrodes and transmission channels in one single step. The electrode is knit using conducting thread while a base fabric is knit using non-conducting thread. The electrode is knit on a first needle bed and the base fabric is knit on a second needle bed opposite to and facing the first needle bed, the two needle beds being separated by a few millimeters. During the knitting process, the surface knit on the first needle bed and the surface knit on the second needle bed may be linked using an isolating thread network that is simply deposited, without forming a mesh, on the fabric, in order to provide the three-dimensional effect. | 06-14-2012 |

20110070840 | Handheld synthetic antenna array - A system for estimating parameters of an incoming signal is provided. At least one antenna is coupled to at least one suitable receiver. The antenna(s) are spatially translated in an arbitrary trajectory. As the antenna(s) is being spatially translated, a data processing means samples the incoming signal at set intervals based on a clock signal provided by a system clock. By sampling the incoming signal at different times at different spatial locations on the arbitrary trajectory, the system acts as a synthetic antenna array. The different samplings of the incoming signal at different times and positions provide signal diversity gain as well as different readings which can be used to estimate and/or calculate various parameters of the incoming signal. The different samplings can be used to detect the incoming signal, estimate its angle of arrival, estimate its time of arrival, as well as other parameters. | 03-24-2011 |
20110070857 | SIGNAL DETECTION IN FADING ENVIRONMENTS - Systems and methods related to the detection of incoming wireless signals. An antenna array is synthesized by having a single antenna, coupled to a receiver, spatially translated along an arbitrary trajectory. As the antenna is being spatially translated, a data processing means samples the incoming signal based on a clock signal provided by a system clock. By sampling the incoming signal at different times at different spatial locations on the arbitrary trajectory, the system acts as a synthetic antenna array. The different samplings of the incoming signal at different times and positions provide signal diversity gain as well as different readings which can be used to detect an incoming signal. The invention is applicable to detecting a wireless communications signal or a GNSS signal under various conditions. The system may include at least one sensor which can provide data for use in calculating data related to the arbitrary trajectory. | 03-24-2011 |
20120259572 | SYSTEM AND METHOD FOR GYROSCOPE ERROR ESTIMATION - Methods and systems for compensating for gyroscopic errors. A system uses magnetometers to detect and measure a magnetic field local to a personal navigation device. When the local magnetic field is quasi-static, the rate of change of the magnetic field is combined with the rotational rate of change of the device. This generates an estimated gyroscope error. The error can then be used to correct for time-varying inherent gyroscope errors. | 10-11-2012 |
20140247186 | Global Navigation Satellite System (GNSS) Anti-Interference using Array Processing - Embodiments of the invention are directed to GNSS anti-interference using array processing. In one embodiment, a device may be configured to receive signals GNSS signals. In one embodiment, the signals may include a superposition of GNSS signals from independent transmitter sources and a spoofing signal. The spoofing signal may include several pseudo random noise (PRN) codes originating from a single transmitter source. In a one embodiment, the device may include multiple radio frequency (RF) inputs connected to multiple antennas and may use a combining algorithm to produce a weighted sum of the antenna outputs. The resultant sum may be passed through an output port of the device that is configured to be coupled to an RF input port of a GNSS receiver. | 09-04-2014 |

20140324624 | WINE RECOMMENDATION SYSTEM AND METHOD - A computer readable medium comprises instructions, which when executed by a data processor of a portable electronic device, cause the data processor to obtain a list of wines available at a commercial establishment; and identify at least one attribute associated with each wine included on the list of wines. The instructions further cause the data processor to, for each wine included on the list of wines, determine a score indicative of a likelihood that the user will purchase the wine on the basis of the at least one attribute and at least one of a characteristic associated with the user and a preference input by the user. Based on the score, the instructions further cause the data processor to identify at least one recommended wine for recommendation to the user; and present the at least one recommended wine on a display interface of the portable electronic device. | 10-30-2014 |
