Abstract: Where a single networked security service supports multiple enterprises, this security service can operate as a shared source of trust so that security devices associated with one enterprise can provide authenticated, policy-based management of computing devices associated with another enterprise. For example, an enterprise firewall can advantageously manage network access for a new device based on a shared and authenticated relationship with the networked security service.

Abstract: A dynamic 3D light scattering particle size distribution measurement device includes a polarization splitter for generating an s laser beam with perpendicular polarization and a p laser beam with parallel polarization that travels parallel to and spaced apart from the s laser beam. A lens is used to focus the s laser beam and the p laser beam onto a common focus area inside a sample holder holding a sample whose particle size is to be measured. An s light intensity detector measures a time-resolved s light intensity from s backscattered light from the focus area. An s-polarisation filter allows perpendicularly polarized light to pass, resulting in s measuring light, and includes a light detector for time-resolved intensity measurements of the s measuring light. A p light intensity detector measures a time-resolved p light intensity detects p backscattered light from the focus area, and includes a p polarization filter that allows parallel polarized light to pass.

Abstract: Systems and methods for improved visualization of non-destructive testing (NDT) measurements are provided. A probe can be employed to acquire NDT measurements of a target. Images of the target can also be captured during testing. The captured images can be analyzed to identify selected objects therein (e.g., the target, the probe, etc.) Graphical user interfaces (GUIs) including the NDT measurements can be further generated for viewing in combination with the target. In one aspect, the GUI can be viewed as a hologram within a display of an augmented reality device when viewing the target. In another aspect, the GUI can be projected upon the target. The GUI can be configured to overlay the NDT measurements at the location where the NDT measurements are acquired. This display of the NDT measurements can help an inspector more easily relate the NDT measurements to the target and improve reporting of the NDT measurements.

Abstract: A synthetic gaslight is described herein. The synthetic gaslight has a translucent upper section that simulates the upper part of a traditional gas flame, a translucent lower section that simulates the lower part of a traditional gas flame, and an opaque isolation section that prevents light from lower section from entering the upper section and that also prevents light from the upper section from entering the lower section. The translucent lower section maintains a constant illumination for the lower part of the simulated gas flame. The translucent upper section has a flickering illumination for the upper part of the simulated gas flame.

Abstract: Methods, systems, and apparatuses, including computer programs encoded on computer-readable media, are configured for spreading, using a first data spreader, first data into a first data frame using a first spreading factor. A first transmitter transmits the first data frame to a diplexer on a first frequency. A second data spreader spreads second data into a second data frame using a second spreading factor. A second transmitter transmits the second data frame to a diplexer on a second frequency different than the second frequency. A diplexer combines the first data frame and the second data frame. A first receiver receives on the first frequency, a third data frame from the diplexer. A second receiver receives on the second frequency a fourth data frame from the diplexer.
