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: Methods, systems, and apparatuses, including computer programs encoded on computer-readable media, configured to receive, at a module from a provisioning server, a node identification and an access code. The module joins a network that the module has not previously joined. The module provides the node identification to the network. The network uses the node identification and access code to verify that the module is valid. The module receives from the network a new encryption key to use when sending data on the network. The module encrypts data using the new encryption key. The encrypted data is transmitted on the network.

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.

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.
