A rearview mirror system comprises a spotter mirror for providing an image of an object in a vehicle's blind zone to the vehicle's operator. A recognition enhancement device is provided with the spotter mirror for drawing the attention of the driver to the spotter mirror when an overtaking vehicle enters the driver's blind zone. The signaling display is activated by a sensing system which senses the presence of the overtaking vehicle in the blind zone. An electrochromic element is incorporated into the spotter mirror to reduce the intensity of light transmitted from the object and reflected from the spotter mirror. Activation of the electrochromic element to darken the spotter mirror will induce the operator to observe the object in the spotter mirror.

An apparatus for removing tissue and / or other material from a patient, particularly a breast of a patient, is provided. The apparatus generally includes a handpiece and a tissue removal mechanism connected thereto. The tissue removal mechanism includes a cannula having an open distal tip and an outer diameter of less than about 5 mm, or less than about 2 mm. The mechanism further includes a rotatable element having a distal portion with helical threading. The distal portion of the rotatable element extends beyond the open distal tip of the cannula in order to allow tissue to prolapse between turns of the helical threading. The apparatus is designed to draw soft tissue into the cannula upon rotation of the rotatable element and without the need for supplemental sources of aspiration.

The improved heat sink system for a lighting fixture includes a conductive mount configured to selectively receive and retain a lighting subassembly. An inner heat sink couples to the conductive mount and is positioned to encompass the lighting assembly. A plurality of cooling fins couple to and extend away from the inner heat sink. An outer heat sink couples to the cooling fins and is offset from the inner heat sink to permit air flow therebetween and over the cooling fins. This enables air convection cooling of the inner heat sink, the outer heat sink and the cooling fins simultaneously to draw heat energy away from the lighting subassembly.

A powered vehicle door system and method in which a motor-driven door opening and closing mechanism and a motor-driven latching mechanism cooperate to enable the door to open from a latched, fully-closed position with improved noise control and improved smoothness of operation. The door can be a tailgate or a swinging or sliding door, and the opening and closing mechanism is operative to place the door in an over-closed position, thus reducing or eliminating the inherent tension placed upon the latch from the compressive force of the seal interposed between the door and the door frame. Optionally, the door latching mechanism assists the door opening and closing mechanism in placing the door in the over-closed position.

A water drop muffler for use in a marine exhaust system to silence exhaust noise while separating entrained water from exhaust gas using hydro-dynamic centrifugal separation principles enhanced by turbulent flow. A muffler housing has a top and a bottom, and defines an internal volume bounded by a generally vertically disposed cylindrical inner surface formed about a longitudinal axis. A generally tubular exhaust inlet is disposed in generally tangential relation with the cylindrical inner housing surface for receiving a mixture of exhaust gas and entrained cooling water. A variable geometry flow channel efficiently transitions the flow for discharge through a vertically elongate opening disposed along the length of the housing inner surface thereby creating vortex flow within the housing to maximize the generation of centrifugal forces. The vortex flow formed within the housing causes the relatively heavy water droplets and water vapor (i.e. steam) to be drawn away from the housing axis toward the cylindrical inner surface. In addition, turbulent boundary layer flow along the surfaces of the variable geometry flow forming channel and the other housing surfaces functions to more efficiently draw entrained water droplets and steam into contact with various surfaces within the housing thereby causing water to coalesce along the inner housing surfaces.
