Abstract: Electron beam profile testing and analysis method is introduced using the MOMS apparatus. The MOMS apparatus includes a Faraday Cup with a knife-wires scanning system which together perform simultaneous measurements. The scanning system has a five-dimensional processing mechanism for measuring different cross sections of an e-beam profile in a path of the e-beam. Measurements are conducted using the scanning system by virtually dividing each cross section into a plurality of subsections and measuring independent current values of at least one wire of the scanning system through which the electron beam passes from every pixel in each of the plurality of subsections. By providing relative movement between the scanning system and e-beam, the measured independent current values are analyzed to obtain the functional form of distribution of current density of the cross-section of the e-beam. The Faraday cup enables simultaneous measurement of the total value of the current.

Abstract: Wheeled walker with an integrated safety system includes a frame, wheels on the frame to enable the frame to be manually moved along a surface, and a belt/tether apparatus including a belt adapted to be attached to a person using the walker and at least one tether connected at a first end region to the frame and at a second end region to the belt. The tether may include an elastic portion that provides a proportional tension as distance beyond a slack distance of the elastic portion increases. This limits separation of the walker from the person attached to the belt.
