Patent number: 7277735Abstract: A method and system for simultaneous ringing in a wireless communication system. Upon receipt of a request to connect a call to a given wireless communication device (WCD), a switch or other entity will determine that the given WCD subscribes to a simultaneous ringing service and will identify one or more other WCDs to simultaneously ring. The switch or other entity will then determine which of those one or more WCDs, if any, are currently operating in the same wireless coverage area as the given WCD and will then simultaneously ring the given WCD and each of the other WCDs, if any, that is determined to be operating in the same wireless coverage area.Type: GrantFiled: April 22, 2004Date of Patent: October 2, 2007Assignee: Sprint Spectrum L.P.Inventors: Dae-Sik Oh, Mark L.

Patent number: 7223264Abstract: Methods for performing coagulation necrosis of biological tissue are provided. The methods include configuring electrode arrays to provide balanced energy density in target tissue volumes using two or more pair of electrodes. The electrode array configuration includes at least one of irregular spacing between one or more pairs of electrodes and one or more electrode diameters. The methods further include deploying each electrode of an array at a selected depth in the target tissue volume in accordance with the configuration.
