Features
Read full description

FLX-Rail®, specially developed for the railway swing monitoring, automatically and continuously measures the maximum vertical deformation of the rail at each passage of a train. This phenomenon is commonly known as “rail swing” or “rail dance”. The FLX-RAIL® is comparable to a connected voidmeter (RTVMD). The instrument is installed between the track and the ballast, fixed under the rail using two powerful magnets: this solution allows quick and easy installation. Another key point is the innovative technology called SBV® (Start By Vibe), patented, which activates the instrument just before the train passes. FLX-Rail® can be equipped with a biaxial inclinometer (MEMS technology) for static rail tilting monitoring and a PT-100 temperature probe for measuring the rail temperature. The FLX-Rail® is the innovative instrument which enables complete and accurate railway swing monitoring. FLX-Rail® LoRa, the autonomous wireless version is now available and its installation has never been simpler: no tools, no glue, no drilling operation are necessary. The measurements are then immediately transmitted via LoRaWAN. FLX-RAIL® LoRa is also certified according to the demanding railway norm EN 50125-3 clause 4.13 to resist to shocks and vibrations. Combining the FLX-RAIL® together with the AimSight camera provides the first and unique global railway infrastructures automatic monitoring solution for : - Railway tracks geometry monitoring (both static & under load) of cant, twist and rail gauge - Railway embankment - Catenary infrastructures (post, contact wire, etc) - Thermal rail monitoring »

Most cleaning apps on the App Store focus on the photo library. Zero Duplicates focuses on your files: the downloads, documents, PDFs, videos and audio files that pile up in the Files app and quietly fill your storage. Zero Duplicates compares files by their content, not by their names. A renamed download, an attachment saved twice, a document copied into three folders: all of them are found, even when the file names look nothing alike. MADE FOR THE FILES ON YOUR DEVICE • Scan any folder you choose: On My iPhone, iCloud Drive, external drives • Downloads from Safari, Mail and Messages • Documents: PDF, Word, Excel, Pages, Numbers, Keynote • Images, videos, audio recordings, archives and more • USB drives and SD cards (with adapter) CONTENT MATCHING File names lie. Zero Duplicates reads the actual content of every file, so duplicates are found even when they were renamed, moved or saved from different apps. AUTO-SELECT IN SECONDS Automatic selection keeps the newest or the oldest file in every duplicate group. Review, tap once, done. No scrolling through hundreds of files by hand. SEE BEFORE YOU DELETE Every duplicate can be previewed before deletion, and you choose which copy stays. At least one version of every file always remains, so losing all copies is impossible. Deletion is permanent, so nothing is removed without a clear confirmation first. PRIVATE BY DESIGN Scanning happens entirely on your device. Your files are never uploaded anywhere. HOW IT WORKS Pick a folder, scan, review what was found, delete with confidence. Three steps to a cleaner device. System files are protected automatically. Perfect for: • Anyone seeing "Storage Almost Full" warnings • People who download and share lots of files • Managing documents, media and work files on the go • Cleaning up iCloud Drive across devices TRY WITHOUT RISK Free to download • Unlimited scans • 500 MB free deletion Premium unlocks unlimited deletion and advanced features.
