Abstract: An electrophotographic (EP) image-forming device and related method are provided for on-line quantitative assessment of the image formation and development process. The EP image-forming device has a primary charger, an exposure device, a toning station, a transfer charger, a fusing station, and a cleaner operatively disposed about a photoconductor. A transmission densitometer is positioned adjacent to the photoconductor. The densitometer determines the photoconductor density and the combination photoconductor and toner density for each step area on the image frame. The density readings are stored in memory. The photoconductor densities are subtracted from the combined densities to provide measured toner densities, which are then averaged for each step area. The average measured toner densities or voltage readings are compared to the aim toner densities or voltage readings for each step in the step tablet to quantitatively assess the image quality of the image-forming process. Preferably, every image frame on the photoconductor is assessed successively.

Title: Electronically controlled prosthetic knee
Inventor: PRATT GILL A
IPC: A61F2/70
Filed: 2001-01-22
Granted: 2008-12-30
Abstract: The present invention relates to a variable-torque magnetorheologically actuated prosthetic knee (110, 210) which utilizes a plurality of interspersed and alternating rotors (120, 220) and stators (130, 230) to shear magnetorheological fluid (130) in gaps formed therebetween. Advantageously, by operating in the "shear mode" there is substantially no or negligible fluid pressure buildup or change. Moreover , the multiple MR fluid gaps or flux interfaces desirably allow for the production of a large torque at low speed without the use of a transmission and also for a wide dynamic torque range to be achieved and add to the versatility of the invention. One embodiment of the invention allows the rotors (120, 220) and/or stators (130, 230) to close th e gaps therebetween to create a frictional torque component, thereby forming a "hybrid" braking system which provides a total torque or damping which is a combination of viscous torque and frictional torque.
