    X-Plane plugin that displays a tablet to aid VR usage

    ...Using a PDF reader breaks the immersion because the virtual aviator either has to take off of their HMD or use other tools that can move windows into VR. AviTab tries to solve this problem by offering a PDF reader inside a native plugin for X-Plane. Using a plugin also opens possibilities for more apps inside the tablet, for example, to display information about the plane status or aid in navigation. When hovering over the edges of the tablet from a short distance, X-Plane will display green bars around the tablet. ...

    RSM

    Radiation Spectrum Method : a modal BPM (Beam Propagation Method)

    RSM (Radiation Spectrum Method) is a 2D rigorous tool to solve the Maxwell equations for the propagation of light in integrated optics or photonics devices. It makes use of an EigenMode Expansion method (EME) to solve the electromagnetic problem. This software running on Windows and MacOS comes with a GUI that permits to define with the aid of files or scripts the arbitrary and complex geometry of the waveguide. Of that way any waveguide geometry can be handled. Several plots are available : refractive index plot, field propagation plot and modes spectrum plot. This permits, with the interpretation of the guided and radiation modes spectrum, a physical understanding of the propagation mechanisms in the integrated optical device under evaluation. ...

    Ethercat analyzer. Pcapng (by wireshark) to cvs files converter.

    To diagnose a problem or simply to study the internal flow of information in an ethercat fieldbus, one of the common practices is to capture the flow of ethercat datagrams with an ethernet sniffer such as Wireshark (www.wireshark.org). Wireshark provides some filters to facilitate data analysis but the high amount of recorded information still makes an analysis complicated for many people who do not have a very deep knowledge of the ethercat protocol and Wireshark tools.
