20080246648 | METHODS FOR RAPID TARGET ACQUISITIONS IN RANGE MEASUREMENT SYSTEMS - A method for acquiring targets within a search area using an electronic device is disclosed. The method involves partitioning a first acquisition time period into a plurality of range gates, simultaneously positioning one or more of the range gates within the search area during a search mode, and transmitting an energy pulse train. Upon receipt of a reflection of the transmitted pulse train, the method records a signal level of the reflected energy pulse train within the first acquisition time period. Based on the recorded signal level, the method advances one or more of the range gates by a prescribed outbound movement increment until the signal level within at least one of the range gates is above a prescribed acquisition signal level threshold. | 10-09-2008 |
20090085798 | METHOD AND SYSTEM FOR OBTAINING IN-PHASE AND QUADRATURE COMPONENTS OF A SIGNAL - A method of obtaining in-phase and quadrature phase components for a narrowband signal is provided. The method includes digitally sampling a narrowband signal at a digital sampling rate to obtain a number of data points. The method subtracts a first portion of the data points corresponding to a first half of one period of the signal from a second portion of the data points corresponding to a second half of the one period of the signal to obtain a number of output data points which is less than the number of data points obtained from sampling the narrowband signal. | 04-02-2009 |
20090303103 | Method and System for Reducing a Leakage Component of a Received Radar Signal - Methods and systems for reducing a leakage component of a received-signal are disclosed. A transmit antenna of a radar system transmits a transmit-signal including a transmit component. A receive antenna of the radar system receives a received-signal including a leakage component and a target component. The received-signal corresponds to the transmit-signal. An overlap determination is made to determine whether the target component overlaps the leakage component and/or is received during a time when the leakage component is expected to be received. If overlap exists, a reduction leakage component (e.g., a previously determined reduction leakage component) is subtracted from the received-signal so as to produce a modified received-signal, the modified received-signal including the target component and substantially excluding the leakage component. If overlap does not exist, an estimate of the leakage component is produced and a reduction leakage component, based at least in part on the leakage component, is produced. | 12-10-2009 |

20120059400 | APPARATUS AND METHODS FOR OCCLUDING A HOLLOW ANATOMICAL STRUCTURE - A clamp having at least first and second elongate clamping portions adapted to be placed on opposite sides of the hollow anatomical structure. The first and second elongate clamping portions respectively include ends coupled together with respective resilient urging members configured to urge at least one of the first and second elongate clamping portions toward the other of the first and second elongate clamping portions from an open position into a clamping position to occlude the hollow anatomical structure. The clamp includes tissue ingrowth structure on the clamping portions. | 03-08-2012 |
20140025058 | ABLATION DEVICE WITH INTERNALLY COOLED ELECTRODES - An electrosurgical end effector for ablating tissue is provided that comprises at least one electrically-conductive ablation member adapted to be connected to a source of RF energy, with the ablation member having a tissue engaging surface and defining an internal fluid passageway. Preferably, the end effector includes two electrically conductive ablation members that are electrically isolated from one another and have their fluid passageways in fluid communication. Alternatively, the end effector may comprise four electrically conductive ablation members arranged as two pairs of ablation members, all of the ablation members having internal fluid passageways that are electrically isolated from each other, with the fluid passageways of each of the four ablation members being in fluid communication with each other. | 01-23-2014 |
