Abstract: The present invention discloses a vacuum chamber having operating pressures in the ultra-high vacuum (UHV) range (10?8 torr to 10?13 torr) and incorporating transparent windows, said windows constructed from transparent materials (preferably glass), and having low helium permeability velocity under operating and storage conditions. Embodiments may also contain surface coatings on windows to reduce helium permeation. Also disclosed herein is a method for vacuum processing said chamber by heating entire chamber and exposing the inside and outside of the chamber windows to helium free environments. Methods for final sealing said chamber are also discussed. The vacuum chamber is useful as a container for optically-cooled atoms for use in quantum information and atomic clocks and as a sensor for magnetic fields, gravitational fields, and inertial effects.

Abstract: A witness testimony collection system may include a storage medium configured to store one or more documents. An interactive pen display device may be configured to transmit, in real time, digital ink markings on a document selected from the one or more documents. A high definition camera may be configured to transmit an image in real time. A mixer may be configured to receive input from the camera, the interactive pen display device and the storage device. The mixer may combine the input from the camera, the interactive pen display device and the storage device into a single output. A screen may be configured to receive input from the mixer. The screen may display an image of the digital ink markings on the selected document and the image from the camera on a single screen.
