Abstract: An electrosurgical device includes a plurality of electrodes arranged to form a tissue treatment surface and a power supply. The power supply is configured to deliver a first drive signal with a first phase to at least a first one of the plurality of electrodes and a second drive signal with a second phase to at least a second one of the plurality of electrodes such that an electric field extends from the tissue treatment surface, where the first phase and the second phase are different. The power supply is further configured to receive an input from an operator of the electrosurgical device, and adjust the first phase or the second phase such that an aspect of the electric field extending from the tissue treatment surface changes in response to the input from the operator.

Abstract: The present invention provides disposable illumination sheaths as a sterile barrier between an imaging device and a patient. An exemplary sheath can generally be usable with any imaging system known in the art, for example, an endoscopic imaging system, and can be designed to cover and/or enclose portions of the imaging device that may be exposed to patient tissue and/or bodily fluids. An exemplary sheath of the present invention can be designed to cover and protect the imaging shaft, optics housing, camera housing, handle, imaging output and/or other electrical and component cords, as well as any other portion of the imaging device that may be exposed to contamination. A used sheath can be disposed of after a first procedure and a new, sterile sheath can be used for a subsequent procedure. In this way, an imaging device can be utilized repeatedly without the need for a full sterilization between each procedure.

Abstract: A unique digital imaging device includes the digital imager, a mammography machine including the digital imager, a method for processing the digital image obtained by the digital imager, a local area network (LAN) comprising a number of mammography machines and one or more work stations, and a wide area network (WAN) for transmitting digital images to remote locations. The digital imager according to the present invention comprises a large area, single exposure digital imaging device is provided that allows a number of electronic imagers to be butted together to form an array of electronic imagers large enough to image an entire breast in a single exposure. A preferred embodiment of the digital imager comprises an optical system, such as fiber optic bundles, optically coupled with the surface of the electronic imager. The optical systems may have a surface larger than the electronic sensors, and may be butted together to provide a gap-free imaging surface.

Abstract: An infra-red sensor system for all weather, day and night traffic surveillance of ground based vehicles. The infra-red sensor system comprises system comprises an infra-red, focal plane array detector, signal processors, a communications interface and a central computer. The infra-red, focal plane array detector senses the heat emitted from vehicles passing within the field of view. Information collected from the array detector is input to signal processors which are programmed with tracking algorithms and other application specific algorithms to extract and calculate meaningful traffic data from the infra-red image captured by the array detector. The meaningful data includes the location, speed and acceleration of all vehicles passing within the field of view of the array detector. The information from the signal processors is transmitted to the central computer via the communications interface for further processing and dissemination of information.
