Abstract: A configurable-width industrial weighing scale configured to hang directly from one of multiple engine-powered lifting machines and/or to couple to a quick-attach plate or other attachment means of an engine-powered lifting machine and configured to directly support a lifting element and/or couple to a quick-attach plate or other attachment means of a lifting element. A weighing element includes front and rear plates in parallel with one another and a weighing assembly therebetween. The weighing assembly may include a strain gauge-based load cell, a shock absorber, a mechanical preload adjustment to control a vertical difference between the front and rear plates, a mechanical linearity control to adjust an angle of the weighing assembly, a carriage alignment bolt to compensate for an uneven surface of a lifting carriage of the engine-powered lifting machine, and/or a mechanical adjustment to compensate for a distance between the front plate and a load.

Abstract: A mobile weighing apparatus includes a base tubing, a column extending from the base tubing, a handle extending from the column, a plurality of wheels, a weighing platform, and a plurality of load cells coupled to or between the base tubing and the weighing platform. The weighting platform may be suspended from the load cells, such as with wire rope bolts, such that a force applied to the column does not affect weighment of an object on the weighing platform. The apparatus may include a kingpin-less swivel rear wheel, a rear wheel brake to preclude rotation of the rear wheel about an axle of the rear wheel, and an actuator to actuate the rear brake when the rear wheel is in any position over a 360-degree range. The wheels may be positioned adjacent respective corners of a triangularly shaped base tubing, and the apparatus may further include a clinometer.

Abstract: A spatial light modulator outputs modulated light including: modulated first light when the spatial light modulator receives first light; and modulated second light when the spatial light modulator receives second light. Projection optics project the modulated light onto: a first pixel region when a component or the spatial light modulator has a first position; and a second pixel region when the component or the spatial light modulator has a second position. The first and second pixel regions partially overlap. A pixel shifter moves the component or the spatial light modulator between: the first position when the spatial light modulator outputs the modulated first light; and the second position when the spatial light modulator outputs the modulated second light.

A folding mirror may be used after the aspheric mirror to further reduce the depth of the enclosure.

Abstract: System and method for thin projection display systems. An embodiment comprises a light source, an array of light modulators optically coupled to the light source, a lensed mirror optically coupled to the array, and a controller electronically coupled to the array and to the light source. The array produces images on a display plane by modulating light from the light source based on image data and the controller provides light commands to the light source and load image data into the array. The lensed mirror reflects modulated light from the array onto the display plane, the lensed mirror comprising a refractive portion and a reflective portion. The refractive portion of the lensed mirror helps to increase the light bending capability to help reduce the overall thickness of a projection display system.
