The EPICS display manager MEDM is a very powerful tool with many features and satisfies most of the needs for synoptic displays. However MEDM is based on MOTIF/Xt and X11, systems/libraries that are getting into age. Moreover applications using those systems are difficult to maintain and to extend. At PSI a new Qt based application was written, reproducing the functionality of MEDM. Moreover a parser was written to convert the MEDM files into Qt files, the resulting displays being an exact reproduction of the MEDM displays. It has to be noticed that the widgets used are not directly epics aware. The idea was to strictly separate the control system from the display part, in order to be able to add other controlsystems if necesssary (which is still the case for our high intensity particle accelerator). An application is never finished and can always be improved and new things can be added. This is therefore also the case for caQtDM. The widgets could be improved, not everything has been finished and bugs will be found. This App is directly build out of the same sources like the linux/mac or windows version with the help of Qt. For using it a http server with the configuration files (network/gateway/environment) and display files is needed.

In a world that is technologically driven, Eyerus was created to utilise the existing technology to help solve one of the biggest pandemics in South Africa โ€“ contact crime, which includes sexual violence, rape, assault and Gender-Based Violence. With almost every South African using a smartphone, the smart thing to do was to create a mobile app designed to provide personal safety for everyone needing the freedom to live without fear, in a society gripped by crime. Eyerus is an automated algorithm that provides personal safety and security in the palm of your hands. You can now move with safety and freedom anywhere, at any time, without fear.

Features Safety in the palm of your hands. Eyerus uses smart technology to give you and your loved one's peace of mind, by keeping you connected and helping within reach, anywhere, anytime. This state-of-the-art innovative technology features: Green Alert Mode โ€“ Safe and Sound The green alert mode indicates you are safe and all is well. When you feel your safety is being compromised you can escalate the alert mode according to the severity of your situation. Amber Alert Mode - Audio Recording By simply shaking your phone you can automatically activate the amber alert mode which triggers live audio streaming to a secure cloud. You can activate the amber alert mode in any situation where you feel unsafe.
