Abstract: A surgical lighting system and a method of rotating a camera of a surgical lighting system includes a light head housing including a plurality of light emitting elements arranged to emit light downward to a region of interest, a handle mounted to and protruding downward from the light head housing, the handle including a handle housing having a sufficient size to be gripped by the human hand, and a camera assembly mounted within the handle housing and including a camera having a field of view that encompasses at least a portion of the region of interest. The camera assembly is mounted within the handle housing for rotation greater than 360 degrees about a rotation axis from a first stop to a second stop and vice versa. The first stop limits clockwise rotation of the camera and the second stop limits counterclockwise rotation of the camera.

Abstract: A surgical lighting system includes a light head housing, a handle, a camera, and an optical fiber cable. The light head housing includes a plurality of light emitting elements therein that are arranged to emit light downward to a region of interest. The handle is mounted to the light head housing and protrudes downward from the light head housing, the handle including a handle housing having a sufficient size to be gripped by the human hand. A camera is mounted within the handle housing, the camera having a field of view that encompasses at least a portion of the region of interest. An optical fiber cable extends from a location within the handle housing and to the light head housing, the optical fiber cable being configured to transmit optical video signals associated with video data captured by the camera to the light head housing.

Abstract: A tubular fitting for connecting electrical conduit has opposite male and female end portions. The male end portion has a cylindrical outer surface with a pair of axially-spaced projections extending outwardly therefrom and is receivable in an existing electrical nonmetallic tubing socket. The female end portion has a schedule 40 socket therein for receiving a schedule 40 solvent cement conduit of the same trade size as the trade size of the electrical nonmetallic tube that is receivable in the existing electrical nonmetallic tubing socket.

Abstract: A transition adapter for connecting together ENT tubing and threaded conduit has an ENT connector socket on one end portion thereof and a threaded socket on an opposite end portion thereon.

Abstract: A tubular reducer fitting for transitioning from an existing ENT socket of one size to an ENT socket of a smaller size. The male end portion has a cylindrical outer surface with a pair of axially-spaced projections extending outwardly therefrom and is receivable in an existing ENT socket. The female end portion has an ENT socket therein. The male end portion is configured for locking reception in a first trade size ENT socket and the opposite female connector end portion has a smaller trade size ENT socket therein.

Abstract: A fitting for attaching ENT tubing to a concrete form has an inverted cup-like configuration with a bottom opening and an internal cavity within a fitting wall. A flange extends outwardly from the fitting wall around the bottom opening and has fastener-receiving holes for attaching the fitting to a plane surface of a concrete form. A socket extends through the fitting wall into the cavity for receiving an end portion of an ENT tube. The socket has a plurality of circumferentially-spaced resilient fingers that are inclined inwardly toward the socket axis for gripping an ENT tube. A pair of opposite fingers have teeth that are receivable in an annular groove in an end portion of a corrugated ENT tube. The teeth have rounded ends to facilitate ratcheting movement of the ENT tube end portion both into and out of the socket.

Abstract: A knockout in a sidewall of a plastic electrical box has a slot for receiving a screwdriver tip to apply a knockout force to the knockout. The slot is located adjacent the box bottom wall to minimize deformation of the sidewall by a knockout force.

Abstract: An electrical outlet box molded of plastic material has a knockout arrangement in a box wall that is formed by inner, intermediate and outer circular grooves that are eccentrically positioned to overlap at a tangent location and define inner, intermediate and outer eccentrically positioned circular knockouts. The grooves vary in depth from a minimum depth at the tangent location to a maximum depth opposite from the tangent location. Areas of increased weakness are provided in the box wall at the bottoms of at least the inner and intermediate grooves, and screwdriver slots are provided in the knockouts opposite from the tangent location.
