20140064032 | Volume rendering of 3D sonar data - Sonar imaging data obtained by sending multiple sonar pings towards an object is reduced by assigning values measured by each sonar ping to bins, where each bin is fixed in World Space, and calculating the opacity of each bin to produce an image of the object. A normal vector associated with each bin is used to calculate the light reflected from a model constructed from the data. The most preferred normal vector is calculated from the vector sum of normals calculated from each ping. | 2014-03-06 |
20140064033 | Method of object tracking using sonar imaging - An object is measured to record the relative surface coordinates. Then, a portion of the object “the front side” immersed in a fluid is imaged by directing a sonar pulse at the object and recording sonar signals reflected from the object with a sonar imaging array. Then, the recorded relative surface coordinates are iteratively fit to coordinates calculated from the sonar image. Thereafter, the coordinates of the surface of the “backside” of the object that is not observable in the sonar image are known, and a computer generated image of the backside is stitched to sonar image so that the object can be viewed from a plurality of viewpoints separated from the sonar imaging array. | 2014-03-06 |
20140064034 | DISTANCE MEASUREMENTS BETWEEN COMPUTING DEVICES - Some implementations provide techniques and arrangements for distance measurements between computing devices.

In some cases, cross correlation may be performed on the streaming data in a search window to determine a timing of a cross correlation peak indicative of the detection of the audio tone in the streaming data. The location of the search window in time may be determined based at least in part on the timing of the detected autocorrelation peak. | 2014-03-06 |

The fluid injector has a control input capable of altering fluid flow relative to a received control signal, which is generated by a controller in response to an electrical signal. The fluid injector produces fluid flow outward and inward in response to the control signal, thereby creating an acoustic wave proportional to the electrical signal. The devices herein may employ valves or not. Synthetic jets may also be used. | 2014-03-06 |

A method of a scanning of a station (STA) may include monitoring a channel during a probedelay based on a MAC sublayer management entity (MLME)-SCAN.request primitive indicating an active scanning for a target Access Point (AP), receiving a frame including a channel congestion indicator from an AP during the probedelay, generating a MLME-SCAN.change request primitive to request a change of a scanning type parameter included in the MLME-SCAN.request primitive when the channel congestion indicator indicates that the channel is congested, generating a MLME-SCAN.change confirm primitive to confirm the change of the scanning type parameter included in the MLME-SCAN.request primitive as a response of the MLME-SCAN.change request primitive, and performing a passive scanning for the target AP based on the MLME-SCAN.change confirm primitive. | 2014-03-06 |
20140064129 | ENHANCED MEASUREMENT REPORTING TO IMPROVE THROUGHPUT WHEN USING MULTICARRIER CELLS - A method for measurement reporting to improve throughput when using multicarrier cells is disclosed. The method can include a wireless communication device performing a first measurement of a primary carrier and performing a second measurement of a secondary carrier. The method can further include the wireless communication device deriving a combined measurement as a function of the first measurement and the second measurement. The method can also include the wireless communication device reporting the combined measurement to a serving network. | 2014-03-06 |
20140064130 | GEOGRAPHIC REDUNDANCY FOR CALL SERVERS IN A CELLULAR SYSTEM BASED ON A BEARER-INDEPENDENT CORE NETWORK - In a bearer-independent core network, the switching and transport of the bearer streams is separated from the processing of call sessions that control the bearer streams. The switching and transport of the bearer streams is executed by media gateways and packet switches in the switching and transport layer of the network. The processing of calls sessions that control the bearer streams is executed by call servers in the call control layer of the network. The switching and transport layer of the network may be implemented using ATM or IP technology. In order to redirect the signaling links to a backup call server, a signaling gateway is used. Each media gateway includes a signaling gateway function. The signaling gateways redirect the signaling links by encapsulating each signaling message in a new packet in one embodiment. | 2014-03-06 |
20140064131 | METHOD AND APPARATUS FOR REPORTING CHANNEL QUALITY INDICATOR IN WIRELESS COMMUNICATION SYSTEM - Provided are a method and an apparatus for reporting a channel quality indicator (CQI) in a multi-node system. A terminal measures the CQI on the basis of a final interference power in which interference from at least one node among a plurality of nodes, from which the terminal receives signals, is reduced, and reports the measured CQI to a base station. Improvement of system performance, such as a data rate increase can be expected. | 2014-03-06 |
