20110205117System and Method for Adaptive Correction to Phased Array Antenna Array Coefficients Through Dithering and Near-Field Sensing - A system and method of adaptively correcting the excitation or receive coefficients for a phased array antenna. For a transmitting antenna, a sensor located in the near field of the antenna is used to sense the antenna transmission. A reference signal that represents the sensor response to a desired antenna transmission that is accomplished with predetermined excitation coefficients is determined. The magnitudes and phases of the excitation coefficients are modified in a predetermined manner to create a modified antenna transmission. An actual signal that represents the sensor response to the modified antenna transmission is then determined. The excitation coefficients are then corrected using the differences between the reference signal and the actual signal, such that the modified antenna transmission becomes closer to the desired antenna transmission. The method and system also apply to a receiving antenna.08-25-2011

20080209494Network architecture for intelligent network elements - Hybrid fiber/coax networks employ the existing cable plant used for cable TV and transmit data signals in a frequency bandwidth above that which is used for cable TV. As this cable plant was deployed in a tree and branch topology, data transmissions may be susceptible to noise, variable transmission loss and frequency dispersion, particularly in the upstream direction. Further, due to the tree and branch topology, homes at the far end of the network experience much greater loss than do the homes that are near to the headend/ONU. The present system, which uses point-to-point data links between intelligent network elements located in the feeder/distribution network to provide reliable, secure, bi-directional broadband access. Digital signals are terminated at the intelligent network elements, switched and regenerated for transmission across additional upstream or downstream data links as needed to connect a home to a headend or router. The intelligent network elements can be co-located with or replace the standard network elements to take advantage of existing network configurations. The standard network elements can be selectively replaced by the intelligent network elements in an incremental approach. A tree-and-branch network architecture is therefore established in which each intelligent network element is assigned a routing ID employed in the point-to-point transmissions while leaving legacy analog signals unimpeded. In this manner, the data links are made over relatively short runs of coax cable, which can provide greater bandwidth than the typical end-to-end feeder/distribution connection between a home and the headend or optical network unit.08-28-2008

20090312692SHEAR STRESS ULTRASONIC HORN FOR ULTRASONIC SURGICAL ASPIRATION - An ultrasonic horn for use with an ultrasonic surgical hand piece including a resonator comprises a contacting annulus having a plurality of angled lands. The lands are alternated around the annulus such that adjacent lands have opposite angles. As a result of the adjacent angled lands, a shear stress field is developed in contacted tissue due to the promotion of refracted longitudinal ultrasonic waves propagating in different directions at the interface to the coupled tissue. The shear stress field enhances the fragmentation and removal rate of fibrous, elastic, and tenacious tissue. The horn is hollow permitting suction to be applied to the tissue for controlling tissue contact with the lands.12-17-2009

20120016926SCALABLE TECHNIQUES FOR PROVIDING REAL-TIME PER-AVATAR STREAMING DATA IN VIRTUAL REALITY SYSTEMS THAT EMPLOY PER-AVATAR RENDERED ENVIRONMENTS - Scalable techniques for rendering emissions represented using segments of streaming data, the emissions being potentially perceivable from many points of perception and the emissions and the points of perception having relationships that vary in real time. The techniques filter the segments by determining for a time slice whether a given emission is perceptible to a given point of perception. If it is not, the segments of streaming data representing the emission are not used to render the emissions as perceived from the given point of perception. The techniques are used in networked virtual environments to render audio emissions at clients in a networked virtual reality system. With audio emissions, one determinant of whether a given emission is perceivable at a given point of perception is whether psychoacoustic properties of other emissions mask the given emission. The segments representing the streaming data also contain metadata which is used both in the filtering and in rendering the streaming data for a point of perception at which the emission is perceived.01-19-2012
