20120155382 | PROVIDING MAGNETIC DEVIATION TO MOBILE DEVICES - A method of providing magnetic deviation corresponding to positions in a wireless communication system includes receiving a request wirelessly for a magnetic deviation corresponding to a position of an access terminal, the request including the position of the access terminal; retrieving the magnetic deviation corresponding to the position of the access terminal from a repository; and transmitting wirelessly the magnetic deviation corresponding to the position of the access terminal to the access terminal. | 06-21-2012 |
20120155770 | MAGNETIC DEVIATION DETERMINATION USING MOBILE DEVICES - An apparatus of a wireless communication system includes: a transceiver configured to receive and transmit information wirelessly; and a processor communicatively coupled to the transceiver and configured to access an image captured by an access terminal of the wireless communication system, a position of the access terminal, and multiple keypoints and a geographical location of each respective keypoint, each geographical location being a location near the position of the access terminal; and determine a magnetic deviation corresponding to the position of the access terminal by calculating a compass bearing and a true bearing to a feature within the image using the position of the access terminal and the geographical location of a keypoint, from the multiple keypoints, determined as corresponding to the feature. | 06-21-2012 |
20120178469 | POSITION DETERMINATION USING HORIZONTAL ANGLES - An access terminal of a wireless communication system includes a transceiver configured to receive wirelessly multiple reference keypoints and a geographical location of each respective reference keypoint, each geographical location being a location near an estimated position of the access terminal; at least one camera communicatively coupled to the transceiver and configured to capture an image; and a processor communicatively coupled to the at least one camera and configured to calculate a refined position of the access terminal, that is more accurate than the estimated position, using first and second horizontal angles between the geographical locations of respective first and second pairs of reference keypoints determined as each corresponding to a respective image keypoint identified within the image captured by the at least one camera. | 07-12-2012 |
20120301011 | DEVICES, METHODS, AND APPARATUSES FOR HOMOGRAPHY EVALUATION INVOLVING A MOBILE DEVICE - Components, methods, and apparatuses are provided that may be used to access information pertaining to a two-dimensional image of a three-dimensional object, to detect homography between said image of said three-dimensional object captured in said two-dimensional image indicative of said three-dimensional object and a reference object image and to determine whether said homography indicates pose suitable for image augmentation based, at least in part, on characteristics of an elliptically-shaped area that encompasses at least some of a plurality of inliers distributed in said two-dimensional image. | 11-29-2012 |
20130310071 | POSITION DETERMINATION USING HORIZONTAL ANGLES - An access terminal of a wireless communication system includes a transceiver configured to receive wirelessly multiple reference keypoints and a geographical location of each respective reference keypoint, each geographical location being a location near an estimated position of the access terminal; at least one camera communicatively coupled to the transceiver and configured to capture an image; and a processor communicatively coupled to the at least one camera and configured to calculate a refined position of the access terminal, that is more accurate than the estimated position, using first and second horizontal angles between the geographical locations of respective first and second pairs of reference keypoints determined as each corresponding to a respective image keypoint identified within the image captured by the at least one camera. | 11-21-2013 |
20140108466 | DETECTION OF PLANAR TARGETS UNDER STEEP ANGLES - Systems, apparatus and methods to create a database by a device (such as a server) and to use the database by a mobile device for detecting a planar target are presented. The database allows recognition of a planar target by a mobile device from steeper angles with minimum impact on runtime. The database is created from at least one warped view of the planar target. For example, a database may contain keypoints and descriptors from a non-warped view and also from one or more warped views. The database may be pruned by removing keypoints and corresponding descriptors of one image (e.g., a warped image) overlapping with similar or identical keypoints and descriptors of another image (e.g., a non-warped image). | 04-17-2014 |

20080232269 | DATA COLLECTION SYSTEM AND METHOD FOR IP NETWORKS - A system operative to collect and analyze data in a digital network includes a probe layer comprising a probe disposed in the digital work. The probe is configured to identify and capture data from frames passing through the probe. The system also includes an analysis layer operative to receive the captured data from the probe. In addition, the system includes an application layer comprising a system master operative to mediate between an application and the probe. | 09-25-2008 |
20080247410 | Creating A Low Bandwidth Channel Within A High Bandwidth Packet Stream - Creating a low-bandwidth channel in a high-bandwidth channel. By taking advantage of extra bandwidth in a high-bandwidth channel, a low-bandwidth channel is created by inserting extra packets. When an inter-packet gap of the proper duration is detected, the extra packet is inserted and any incoming packets on the high-bandwidth channel are stored in an elastic buffer. Observing inter-packet gaps, minimal latency is introduced in the high-bandwidth channel when there is no extra packet in the process of being sent, and the effects of sending a packet on the low-bandwidth channel are absorbed and distributed among other passing traffic. | 10-09-2008 |
20090109973 | Programmable passive probe - A configurable probe takes advantage of inter-dependent probe control elements that pass data control signals from one control element to the other for controlling data extraction. The control elements operate in parallel on one word at a time, based upon a state established by one of the control elements. The data to be considered is established by timing offsets dependant upon packet header lengths, and a function to be performed on the data is controlled by individual control units based upon template information individual to each control element. The probe is agnostic about protocols. It operates on stream of packet words and executes its functions according to defined templates. It is the host that controls the probe and determines what protocol header to parse and how. The controlling host instructs the probe via defined templates that act as state machine definitions what to do and when. | 04-30-2009 |
