Abstract: A method for automated design of orthotic and prosthetic devices has been developed. The method includes scanning a three dimensional model of the patient's limb with a laser scanner. The model is loaded into a computer for use in manufacturing an orthotic or prosthetic device. Before the model is used, it is modified by reducing the overall volume of the model by up to twelve percent of the total volume. Also the model's distal end length is reduced by a calculated percentage of the thickness of a prosthetic liner to be worn with the prosthetic device.

Abstract: In an electrophotographic printing machine, a layer of insulating fluid containing micelles is positioned over a photoreceptor. The micelles are migrated onto the surface of the photoreceptor. The photoreceptor is exposed to inject charge carriers into the insulating fluid and selectively neutralize micelles to form an electrostatic latent image. The latent image is transferred to a dielectric surface and developed.

Abstract: An automatic development control for use in an electrophotographic apparatus. The control includes a pair of substantially planar members forming a channel therebetween through which developer flows. One of the members is constructed such that an electrostatic charge pattern is periodically formed on the surface thereof, the charge pattern being developed by the attraction of toner thereto which toner has a charge opposite to that forming the charge pattern. The member on which the developed charge pattern is formed includes a uniform, transparent conducting substrate covered with a transparent insulating layer on top of which is deposited a set of spaced-apart, opaque and electrically conducting fingers. Thus, the one member includes alternate opaque and transparent areas.

The coating material occupies at least a substantially equal position in the Dark Charge Injection Series as any pigment in the imaging suspension. Subsequent or simultaneous electromagnetic radiation to which at least some of the particles are sensitive then results in the formation of optically positive and negative images.

Abstract: An improved photoelectrophoretic imaging method is disclosed wherein the imaging suspension is brought into contact under a first electrical field with a blocking layer having a coating which interacts, in the dark, with the pigment particles of the imaging suspension so as to provide a uniformly charged imaging suspension. The imaging suspension is then exposed to appropriate electromagnetic radiation while under a second electrical field. A second blocking layer, free of said coating is employed to produce positive and negative images.
