Abstract: A light-emitting system is provided which is removably attachable to headgear for personal illumination to enhance visibility of the user to others. The light-emitting system includes a housing that defines a receiving aperture and is configured to surround a portion of the headgear when the light-emitting system is removably attached to the headgear for use. The light-emitting system further includes at least one lens and a plurality of lighting elements coupled to the annular housing which are configured to selectively generate a halo or at least a partial halo of light that radiates outwardly away from the annular housing through the at least one lens to provide enhanced personal illumination.

Abstract: A kayak paddle having at least one paddle blade is made by laying a first resin impregnated fiber preforms in a lower half of a split mold. The split mold has a bifurcated channel for producing a bifurcated rib in a back face of the paddle blade. One end of a paddle shaft is inserted into a cylindrical recess in the lower mold half, and a bifurcated foam core in inserted in the lower mold half over the bifurcated channel. A second resin-impregnated fiber preform is laid over the first fiber preform, and an upper half of the split mold is closed over the lower mold half from one end in clam-shell fashion. Heat and pressure are applied to press the molds together to create thereby a fluid wall of liquid resin which advances through the fiber preforms as the mold closes, driving air out of the fabric preforms as the resin advances through the fiber preforms, and curing the resin to produce a solid fiber-reinforced resin matrix paddle blade bonded to the paddle shaft.

Abstract: An ultrasonic diagnostic imaging system cart is provided with an articulation mechanism for the image display. The articulation mechanism is pivotally mounted to the cart and to the display and includes an intermediate pivot elbow which allows the display to be moved laterally and forward and back from its nominal home position. One arm of the articulating mechanism is inclined to allow the display to clear other components of the cart when articulated and to prevent the development of pinch points. One of the joints of the articulating mechanism includes a locking device which selectively locks the joint to alter the articulation characteristic of the mechanism.
