Abstract: A motorcycle helmet that includes one or more white light type beam forming LEDs (LEDs with lenses that form a beam) mounted in the front of the helmet, such as the helmet forehead area. The LEDs may function as a headlight that may supplement the motorcycle headlight. The beam(s) projected by the LEDS can be steered or aimed at an object by the helmet wearer and may help the rider and motorcycle be more visible to oncoming vehicles or vehicles entering from a side road while at the same time having a downward pointing aspect and a power hat does not create glare for other drivers. The LEDS may be in a self contained module mounted on the outside of the helmet. The LEDs may be mounted or embedded in the outer shell of the helmet with the batteries and electronics being inside the shell and within the foam type compressible inner shell. The batteries and electronics may also be within the helmet neck roll near the bottom rim of the helmet.

Abstract: A valve body assembly for being mounted adjacent an annulus within a heart. A first retainer is attached to the valve body assembly for engaging a first side of the annulus. A second retainer is attached to the valve body assembly and includes a resiliently-deformable retaining member for resiliently engaging a second side of the annulus. The resiliently deformable retaining member is collapsed to a size permitting it to be inserted into through the annulus and positioned adjacent the second side of the annulus. The retaining member is then allowed to expand such that it resiliently engages the second side of the annulus.
