摘要： An exercise device employing side-by-side pivotally supported moving surfaces. In one particular example, an exercise device employs a first belt deployed about a front roller and a rear roller and an adjacent second belt deployed about a front roller and a rear roller. The rear of the belts in the area of the rear rollers are pivotally secured and the front of the belts in the area of the front roller are adapted to reciprocate in an up and down motion during use. In some implementations, the moving surfaces include an interconnection structure such that a generally downward movement of one surface is coordinated with a generally upward movement of the other surface. In other implementations, the moving surfaces are operably associated with one or more resistance elements that effect the amount of force required to pivot or actuate the moving surfaces.

摘要： An afocal beam system corrects excess diffraction from phase error in microelectromechanical mirror offsets. One invention aspect interposes an opposing phase difference, between rays reflected at adjacent mirrors, varying the difference with mirror angle to make it roughly an integral number of waves. Mirror-array (not one-mirror) dimensions limit diffraction. Another aspect sharpens by generating and postprocessing signals to counteract phase difference. A third has, in the optical path, a nonlinear phase-shift device introducing a phase shift, optically convolves that shift with others from mirrors, then deconvolves to extract unshifted signals. A fourth varies mirror position in piston as a function of mirror angle to hold phase difference to an integral number of waves. A fifth aspect has, in the path, at least one delay element - whose delay varies as a function of mirror angle. A sixth has another mirror array in series with the first, matching their angles to introduce opposing phase difference.

摘要： Selected scene regions are imaged. IMAGING CHANNEL: mirrors (preferably MEMS) address an imaging sensor to regions. CALIBRATION CHANNEL: the mirrors direct radiation from a source to a calibration sensor, along an imaging-channel segment. Beam splitter(s) let the channels share optical path at the mirrors. To minimize imaging-channel diffractive blur, the calibration channel modifies wavefront angle and smoothness at the mirrors—measuring (and setting mirrors to optimize) PSF sharpness, then applying these measurements (and settings) to optimize imaging-channel settings by iterative multidimensional gradient search. An afocal lens receives scene radiation, magnifying deflection at the scene. An FOR is imaged on the imaging sensor; the mirrors address the sensor to a narrow FOV within the FOR; the lens enlarges deflections to cover the FOR. Plural diffraction-grating orders communicate between calibration source and sensor when the selected region is in plural scene portions, regardless which FOV is addressed.
