摘要： A hysteresis brake including a casing having internal alternating first slots and first teeth, a pole having external alternating second slots and second teeth, a rotor including an annular portion located in spaced relationship between the casing and pole, and structure for permitting the pole and casing to be rotationally adjusted relative to each other and to lock the first slots and teeth of the casing in a rotationally adjusted position relative to the second slots and teeth of the pole to cause the brake to provide a torque output of a substantially predetermined value at a predetermined current. A method of calibrating a hysteresis brake to provide a torque of a substantially predetermined value at a predetermined current including the steps of rotating the casing and pole relative to each other to a position which provides substantially the desired torque at the predetermined current, and locking the casing and pole to each other in that position.

摘要： An image display system including an illumination source configured to emit a light beam, a polarizing beam splitter, and an image-forming device. The polarizing beam splitter includes a reflective polarizer and an absorptive polarizer disposed adjacent to the reflective polarizer, where the absorptive polarizer is configured to receive a first portion of the light beam that has transmitted through the reflective polarizer. The image-forming device is disposed to receive a second portion of the light beam that has been reflected by the reflective polarizer.
