Abstract: A device for distributing gas near a weld location includes a cap, a funnel, an inlet, and an aperture. The cap includes a sidewall and an annular lip, and defines a reservoir between the sidewall and the annular lip. The annular lip includes a proximal-most edge. The cap defines an opening, and defines a longitudinal axis. The funnel is disposed adjacent a distal end of the cap. The inlet is disposed in mechanical cooperation with the cap. The aperture is disposed through the sidewall of the cap and is in fluid communication with the inlet. The aperture is disposed distally of the proximal-most edge of the annular lip. Gas is configured to flow through the inlet, through the aperture and into the reservoir. The reservoir is configured to allow the gas to uniformly overflow the proximal-most edge of the annular lip and flow distally through the opening defined by the cap.

Abstract: An electrosurgical instrument includes first and second jaw members each including an outer jaw housing, a tissue-treating plate, and a longitudinally-extending knife channel. The electrosurgical instrument also includes a knife actuator and a knife assembly operably coupled to the knife actuator. The knife assembly includes an elongated tube defining a longitudinal lumen and an elongated shaft having a proximal portion coupled to the knife actuator and a distal portion configured to be received through the longitudinal lumen. The distal portion of the elongated shaft includes an enlarged distal end portion configured to prevent movement of the elongated shaft relative to the elongated tube. The knife assembly also includes a knife blade having a pair of opposing lateral sides and a sharpened distal end configured to cut tissue. The elongated tube is configured to be coupled to one of the pair of opposing lateral sides of the knife blade.

Abstract: A video lighthead mountable to a video camera and having a dimmer control that varies the intensity of the light output from the lighthead using pulse width modulation techniques. A photo sensor measures the intensity of light reflected from a subject in front of the lighthead. The intensity of light output from the lighthead is adjusted by control circuitry in response to changes in measured reflected light intensity to maintain a constant level of illumination. The adjustment is carried out by modifying the duty cycle of a pulse width modulation circuit. The duty cycle adjustment of the pulse width modulation is also used to compensate for supply voltage variations in order to maintain constant light output.

Abstract: A digital data receiver includes tunable analog components having variable parameters that are responsive to the bit error rate (BER) of the decoded digital data. The analog components include a quadrature generator having a tunable phase shifter, an analog filter having a tunable bandwidth, a tunable magnitude equalizer circuit, a tunable group delay equalizer circuit, and an amplifier having an adjustable gain. The tunable components are controlled by tuning control signals that incorporate digitally-produced fine tuning signals. The digital tuning signals are altered in accordance with realtime changes in the BER.
