An electrosurgical system includes a generator for generating radio frequency (RF) power, and an electrosurgical instrument including at least three electrodes. The generator comprises an RF output stage having at least a pair of RF output lines, a power supply coupled to the output stage for supplying power to the output stage, and a controller capable of varying the RF power signal supplied to the output lines. The system also includes a selection circuit having at least three output connections each in electrical connection with a respective one of the at least three electrodes. This selection circuit operates to vary the coupling between the RF output stage and the three or more output connections. A switching device operable by the user causes the selection circuit to vary the electrode or electrodes to which RF power is supplied, and also causes the RF power signal supplied to at least one of the at least three output connections to vary depending on the electrode or electrodes to which RF power is supplied. In one arrangement of the selection circuit, one of the electrodes has no direct connection to the output stage of the generator and is connected via a capacitor to another of the electrodes.

A method called the evolvable interference management (EIM) method is disclosed in this patent for avoiding interference and collision and increasing network throughput and energy efficiency in wireless networks. EIM employs sensitive CSMA/CA, patching approaches, interference engineering, differentiated multichannel, detached dialogues, and/or spread spectrum techniques to solve the interference and QoS problems. EIM-based protocols can considerably increase network throughput and QoS differentiation capability as compared to IEEE 802.11e in multihop networking environments. Due to the improvements achievable by EIM, the techniques and mechanisms presented in this application may be applied to obtain an extension to IEEE 802.11 to better support differentiated service and power control in ad hoc networks and multihop wireless LANs. New protocols may also be designed based on EIM.

A method and apparatus for dynamically modifying search results “on the fly” based on the behavior of the user currently conducting a search. In one embodiment, data regarding user behavior is gathered from virtually any activity, including clicks on links, dwell times, downloads, transactions and cursor movements. Subordinate keywords are generated to reflect the intent of the user as inferred from the user's behavior. Subordinate keywords, as opposed to traditional primary keywords, are keywords that are identified as important to the search, but are not necessarily essential for a matched document. They are automatically generated by the system from a variety of places, such as documents clicked on by the user as well as documents that are skipped. The system uses the subordinate keywords to dynamically re-rank matched documents and advertisements to best reflect the inferred intent of the user in order to continuously provide the most relevant results.

A multi-user wireless communication system for use in an enclosed space includes a distributed aperture antenna having multiple apertures distributed along an outer shield of the antenna. The apertures allow radiated energy to leak from the antenna and form low-power, localized electric fields that can couple receivers to the antenna. The multiple electric fields ensure that the electric field strength is distributed evenly throughout the communication system. The low-power electric fields also reduce the likelihood of electric field leakage that may cause interference with other communication systems outside the enclosed space.
