Publication number: 20230222103Abstract: Embodiments are directed to synchronizing files between client devices utilizing different file systems with different filename restrictions. Generally speaking, a server of a cloud-based storage environment can, upon generation of a file or receiving a file from a first client device, detect any “illegal” characters therein, i.e., characters that are predefined by a file system of a second client device of the environment as being impermissible for use in a filename, and substitute a replacement character for those illegal characters. This replacement character can comprise a character that is permissible by the file system of both the first and second client devices, thereby allowing synchronization and access. Additionally, the server(s) can identify the original filename from the first client device and substitute the replacement characters back to the original filename when the file is being accessed by or synchronized with the first client device.Type: ApplicationFiled: January 10, 2022Publication date: July 13, 2023Inventor: David Sawyer

Patent number: 11402304Abstract: An environmental sampling system includes a passage in an aircraft component and a removable collector disposed in the passage. The passage has an inlet at a first region and an outlet at a second region. When the aircraft component is in operation the first region is at a greater pressure than the second region such that air flows through the passage from the inlet to the outlet. The removable collector is configured to retain constituents from the air and to react with the media designed to mimic corrosion effects seen at higher temperatures on engine parts.
