Abstract: Techniques are provided for creating a virtual environment that can be used for virtual trainings. The virtual environment is configured so that the environment can be viewed using a head-mounted display. A computer system can receive a learning objective from a client and the computer system can present the client with a series of question strings about the objective. Based on answer strings received from the client, the computer system can add skill frameworks, interactive frameworks, positional information, and timing information to fields in a training plan table. The computer system can receive visual content from the client or retrieve visual content from a visual content database. Using the training plan table, interactive frameworks can be added to visual content to produce a virtual environment.

Abstract: Embodiments can use a model for training according to embodiments of the present disclosure. In some embodiments, a model can be created from actual video. The model can be a spherical video. In this manner, users can be immersed in real situations, and thus the user can get more experience than the user otherwise would have had. Various technical features can be provided for enhancing such a system, e.g., synchronization of pointers on two screens, camera rigs with extended view to allow the camera rig to be placed further from a location of the players, analytics for rating users and controlling playback of a next play (action interval), and for allowing a user to feel translation while in a model.

Abstract: A drive mechanism for back pressure regulator used in liquid chromatography, supercritical fluid chromatography, or supercritical fluid extraction allows very fine automated control over a very wide range of pressures by combining a linear actuator compressing a spring, pushing a pin. The nozzle assembly of the regulator comprises a flow through chamber containing a diaphragm and a seat, in which the pin pushes the diaphragm against the seat, together with an upstream pressure sensor and electronic feedback control to the motor of the actuator. The BPR of the embodiments exhibits high pressure stability and extremely low pressure noise, even at moderate to high pressures. The exemplary BPR can be use at either constant pressure or to generate pressure programs where the pressure is varied versus time. Further, the nozzle assembly has a field-replaceable head, requiring no mechanical adjustment on replacement.

Abstract: A height adjustable paving stone screed for use in an area bounded by a course of paving stones includes an elongated board. A pair of right angle brackets are mounted on top of the board. Slidably attachable to each right angle brackets include a pair of further right angle brackets, each adjustable vertically with respect to the first right angle bracket. The bottom of each angled bracket is flush with the top the paving stones. Likewise, the bottom surface of the board is even with bottom surfaces of the paving stones, whereby sliding movement of the board establishes a flat plane of bedding material bed at a depth equal to that of the course of paving stones, in the area to support paving stones to fill the area. Sliding movement of the board occurs, establishing a flat plane of to flatten the bedding material for the paving stones.
