An illumination system (10,30,100,130,150,180,200) for hard copy applications including an elongated array (32) of light emitting elements (34) in combination with a light mixing element (42,46) for mixing the light from the individual elements in the lateral or cross-process direction. A curved array (32) or linear array (102) of light emitting elements with an aspheric lens (108) may be utilized, with a cylindrical lens (36,106) compressing the beam of light in the vertical or process direction. The light mixing elements (42,46) are preferably comprised of holographic diffusers. Sufficient mixing of the light from the array is achieved in the cross-process direction whereby a reduction in light output of one light emitting element does not generate a significant localized reduction in intensity at the elongated spatial light modulator. Preferably, the spatial light modulator is a digital micromirror device (DMD), but may also comprise of other devices including those of the transmissive type, including liquid crystal devices.

An orthosis for powering the walking movement of a paralyzed wearer, comprises torso members to be firmly connected to the opposite sides of the wearer's torso. A pair of leg braces is connected to the torso members. Each leg brace comprises a thigh member pivotally mounted at a hip joint to one torso member on one side of the wearer. A shank member connected to the shank and foot of the wearer, is pivotally mounted at a knee joint to each thigh member. A four link drive mechanism which is powered by a rechargeable power unit mounted on the torso member, swings the thigh member forwardly and rearwardly about the hip joint. A knee lock keeps the knee joint locked during the rearward movement of the thigh member and during a portion of the forward movement of the thigh member. At an appropriate point during the forward movement of the thigh member, a cam operated crank unlocks the knee joint and swings the shank member rearwardly to simulate a natural forward step. As the thigh member reaches its maximum forward position, a return spring pulls the shank member forwardly until it is substantially parallel to the thigh member.
