Abstract: A processes and precursor are provided for use in selective laser sintering (SLS) that can create uniform packing densities that create good prints of 3D articles with a decrease in voids and incomplete infill. The resulting articles are electrically conductivity owing to a graphene coating thereby rendering such articles amenable to electroplating, or electrostatic coating processes. The process and precursor provide small diameter filled polymeric materials for 3D printing that are commercially viable to produce an article in a cost effective manner that has superior properties compared to conventional parts owing to reduced void volume and less residual inter-particle stress. The distribution of particles is spherical in shape and have a mean size polydispersity that varies by less than ±5% in diameter. As a result of the control of polydispersity, the particles have the attribute of spontaneously forming closed packed arrangements common to crystals.

Abstract: A virtual paper system configured to receive, store and display data. The virtual paper system comprises a virtual paper device having processing electronics and a memory device coupled to the processing electronics. The virtual paper device further includes a display coupled to processing electronics and configured to be viewed from a front-side of the virtual paper device. The display is also configured to be a touch screen display. The virtual paper device also includes communication electronics configured to provide data communication with at least one of an external device and an external network, a power system configured to provide power to the virtual paper device and an encapsulation layer. The encapsulation layer is configured to cover the front side, sides and at least a first portion of a backside of the virtual paper device. The virtual paper system further comprises a user interface device configured to interact with the display of the virtual paper device.

Abstract: Systems, methods and apparatus are provided through which a holder of a portable electromagnetic energy detector has a base and a pocket. The pocket is fixedly attached to the base and in some embodiments is not greater in height than a border area of the portable electromagnetic energy detector.

Abstract: An x-ray detector panel support is disclosed that is formed with radiation absorbing material to reduce the reflection of x-rays off anything behind the scintillator, which may include the geometry of the panel support, the electronics, and the back cover of the x-ray detector. The absorbing material may take the form of a discrete layer secured to or otherwise disposed within the panel support. The radiation absorbing material may also be mixed with the base materials used to fabricate the panel support. As such, when the panel support is formed, it includes radiation absorbing components. The radiation absorbing material may include lead, barium sulfate, tungsten, as well as other materials. The panel support is constructed to inhibit the detection of backscattered x-rays without significantly increasing the size or weigh of the x-ray detector. The panel support is applicable with stationary or fixed as well as portable x-ray detectors.
