Abstract: Disclosed are systems and methods for wirelessly recording multi-track audio files without the data corruption or loss of data that typically occurs with wireless data transmission. In some aspects of the present invention, each performer is equipped with a local audio device capable of locally recording the respective performer's audio while also transmitting it to a master recorder. The locally recorded audio may then be used to repair or replace any audio lost or corrupted during transmission to the master recorder. Such repair or replacement may be performed electronically or via playback of the locally recorded audio. In other aspects of the present invention, a master recorder is not required since all locally recorded audio may be combined or otherwise processed post-recording. Locally recorded audio may include identifiers to aid in post-recording identification of such audio. A multi-memory unit is also provided to facilitate manipulation and processing of audio files.

Abstract: Apparatus and methods for treating back pain of a patient by denervation of an intervertebral disc or a region of the posterior longitudinal ligament by the controlled application of heat to a target tissue. In one embodiment, the invention may include a procedure combining both decompression of a disc, and denervation of the annulus fibrosus. In one embodiment, a method of the invention includes positioning an active electrode of an electrosurgical instrument in at least close proximity to an intervertebral disc, and applying at least a first high frequency voltage between the active electrode and a return electrode, wherein nervous tissue within the annulus fibrosus is inactivated, and discogenic pain of the patient is alleviated.

Abstract: An electrosurgical method for treating open angle and narrow angle glaucoma, comprising positioning an active electrode in close proximity to a drainage angle of the eye, the active electrode disposed on a distal end of a shaft; and applying a high frequency voltage difference between the active electrode and a return electrode sufficient to ablate and coagulate target tissue in the vicinity of the drainage angle, to create drainage canals with prolonged patency.

Abstract: A method for treating a bone body comprises inserting a probe having at least one active electrode into the target tissue and applying a voltage difference between an active electrode and return electrode to ablate the tissue. The method is particularly directed to removing tumors in a bone body and or removing cancellous bone in a bone body. The bone body may be a vertebral body. An apparatus includes a plurality of active electrodes and a distal section including two bends. The bends serve to prevent the active electrodes from impinging upon the shaft of an introducer needle. Also, a kit includes an electrosurgical probe, an electrosurgical generator, an introducer needle, and a fluid connector to connect the introducer needle to a fluid source such that liquid may be supplied to the target site during an application.

Abstract: A television picture wiping arrangement is disclosed, in which the picture is notionally divided into a plurality of portions and a storage means, such as a matrix store, is provided having a storage address corresponding to each portion. Switching information relating to a sequence of picture content replacement for the portions, usually one portion at a time, is loaded into the storage means, and the information is scanned to generate a switching signal which effects the desired replacement sequence.
