A collimator is compact and uses power efficient light emitting diodes as the illumination source to generate a test image in collimated space. The collimator provides a test image across a wide field of view, which is useful for calibration of optical devices that have a wide field of regard. An optical projection system in the collimator utilizes an array of light emitting diodes, whose light is converged by a Fresnel lens, through a holographic diffuser plate, onto a target plate bearing the test pattern to be projected out into collimated space through a converging lens. An alignment structure provides translation of the target plate along the main axis of the collimator and provides rotational freedom about two axes (vertical and horizontal) via a gimbal structure mounted on the translation mechanism.

Hollow fan blades for turbo fan gas turbine engines are formed of two separate detail halves. Each detail half has a plurality of cavities and ribs machined out to reduce weight. These detail halves are subsequently bonded and given an airfoil shape in the forming operation. In the present invention, the ribs are oriented biased to provide stiffness as needed in different sections of the fan blade with smooth transitions between regions. The ribs and cavities do not run solely radially or chordwise, but curve and change direction. The path of each cavity is curved sufficiently to eliminate any regions with long, straight cavities, which would have low inertia in cross sections through the cavity parallel to the rib. Preferably, cavities do not continue straight in any direction for lengths greater than half the blade chord (e.g. leading edge to trailing edge) before curvature causes the rib to intersect cross section.

A support apparatus for use during plyometric exercise. The apparatus includes a resilient body having a cuboid shape. A flexible cover is provided that surrounds the body. The cuboid body has a height, width and depth which are all of different lengths to each other such that the apparatus may be arranged in three different orientations in which an uppermost face defines a landing platform of three different heights. The body includes a foam core and a shock absorbing layer located at and bonded to the outer surface of the core that surrounds and encapsulates the core. The shock absorbing layer is formed of a foam material having a density greater than the foam core and is located at all six sides of the apparatus such that an intermediate layer is located at the upper face of the apparatus to define a landing platform whatever the orientation of the apparatus.

A temperature door for air-handling system of a heating, ventilating, and air conditioning system for a vehicle is disclosed, wherein a cost and a weight of the system are minimized and a temperature stratification, a flow efficiency, and a NVH / noise of the system are optimized.

A foldable panel supporter includes a supporting leg frame and a supporter joint, wherein the supporting leg frame includes a lower supporting frame and an upper connecting frame which includes a pair of L-shaped resilient connecting arms adapted for being inwardly and slightly pressed. The supporter joint has a folding channel provided thereon to receive the two connecting arms of the upper connecting frame, wherein the folding channel has two holding portions at two ends thereof and a retaining portion extending between the two holding portions. The retaining portion has a width narrower than the two holding portions, wherein each of the holding portions is shaped and sized to receive the connecting arms therein, wherein by slightly and inwardly pressing the resilient connecting arms to an extent that a distance between the resilient connecting arms is equal to the width of the retaining portion, the upper supporting frame is capable of sliding form one of the holding portion to another the holding portion.

In a vehicle door structure, a beam member (21) having a S-shaped cross section and extending in a fore-and-aft direction of a vehicle body is attached to an inner panel (15), and the upper edge of the inner panel (15) is formed by the beam member (21). Thereby, a crash load of a frontal crash is transmitted in a favorable manner, and energy of a side impact is adequately absorbed without incurring a cost increase or a weight increase owing to the use of the door beam.

A thermal management system for a battery pack includes a plurality of main bodies disposed in a stack, an inlet conduit and an outlet conduit in fluid communication with the plurality of main bodies, and a retention panel coupled to the plurality of main bodies. The main bodies include a thermal fin and conduit and are formed using an extrusion process, which minimizes a weight of the thermal fin and heat sink while minimizing a cost of the thermal management system.
