The present invention relates to a device and a system for debugging a solid state disk device, the device comprising: a joint test action group add-on board; and a Raspberry Pi. The Raspberry Pi comprises a general purpose input output interface coupled to the joint test action group add-on board; and a processing unit coupled to the general purpose input output interface. The processing unit is configured to emulate a plurality of joint test action group commands to the solid state disk device through the general purpose input output interface to dump data generated by the solid state disk device during runtime of the solid state disk device. Using the device as described above can reduce the cost required to debug the solid state disk device.

This invention relates to the field of intelligent driving assistance technology, specifically disclosing a driver state monitoring system based on intelligent image recognition. Built on a Raspberry Pi embedded platform, it includes a video acquisition module, a core algorithm processing module, and a peripheral control module. The video acquisition module is compatible with USB or CSI cameras, acquiring and preprocessing driver facial images. The core algorithm processing module incorporates a lightweight facial key point detection model to extract facial features and identify dangerous behaviors such as closed eyes and head tilting, and features a feature calibration and fatigue grading mechanism. The peripheral control module connects to alarm and display components, triggering corresponding warning actions and can be expanded to include multiple alarm methods. The system can also track continuous driving time and expand remote monitoring functionality. This invention features low hardware cost, low power consumption, convenient deployment, fast edge-side inference response, and accurate monitoring. It is adaptable to multiple scenarios, requires no manual intervention, comprehensively prevents fatigue driving, and is easy to deploy on a large scale.
