The system software runs on an embedded processor dedicated for video capture by CSR plc. The software is written in C code and compiled using SDE 6 on Windows. Software was debugged using Windows simulator. The device makes use of source code provided by the chip manufacturer.
This source code is compiled with the custom software such that the user of the device has no opportunities to interact directly with this software or replace it by other versions of the software. This source code is an integral part of the solution that has been verified and validated.
The device is a specially designed camera intended to guide patient intubation. The system software provides access to the device functionality by graphical user interface controlled by 6 content sensitive buttons on the device.
Logically, the software is divided into three features:The software automatically starts up in recording mode. This provides live footage from the video camera that can optionally be recorded to internal memory for future reference. The user can also save still images on the device memory by pressing the provided button.
If the user chooses to save the video to memory, the software compresses the video stream and saves it to internal flash memory.
The Playback mode feature makes it possible to playback previously recorded video footage and view previously taken still photos. To enter this mode, going to the main menu of the device accesses it:
If My Files is chosen, the user enters playback mode.
