Abstract: Embodiments described herein provide an optical system having a light source (e.g., LED) and a high numerical aperture multi-element optical stack. According to one embodiment, the optical stack can reimage an entrance aperture. The multi-element optical stack can include a number of optical elements forming a series of lenses. The series of lenses comprises, a first lens positioned to receive light emitted in a first beam angle and a second lens more distal from the LED than the first lens, the second lens defining a second lens exit aperture that has at least a minimum area necessary to conserve radiance for the emission beam angle in air. The lenses in said series of lenses are configured, in combination, to successively reduce a beam angle of light from the first beam angle to the emission beam angle.

Abstract: a hard drive carrier is disclosed that includes a detachable tab on the top wall of the frame of the carrier. When the tab is detached a hard drive can be placed in the hard drive carrier in a forward position. When the tab is in place, the hard drive can be retained in the frame of the hard drive carrier in a rear position. The top wall of the frame and the top guide rail include a set of alignment holes to accommodate the positioning of the hard drive in a forward position or a rear position.

Abstract: A flexible drive carrier is disclosed. The drive carrier includes flexible elements that accommodate variations in sizes of hard drives as well as variations in computer chassis. The drive carrier forms a precise fit within a computer chassis. A drive carrier that does not accommodate a hard drive is also disclosed.

Abstract: A support apparatus includes a first member and a second member. Each member has a first and a second portion. The first portions of the members are spaced apart and the second portions of the members are interconnected. The first member is a ribbed member in a first orientation and the second member is a ribbed member, identical to the first ribbed member, attached to the first ribbed member in a second orientation inverted from the first orientation.
