Abstract: A machine failure analyzing system includes a wearable electronic device is for a user to wear, a controlling and processing device provided with a machine history database and a failure causes analyzing unit. When a specific machine is malfunctioning or in a failure status, the controlling and processing device utilizes a machine status data collecting unit to collect machine status data from the specific machine. Subsequently, based on the machine status data, the failure causes analyzing unit is configured to find relative failure causes from the machine history database, thereby generating at least one troubleshooting solution. As such, under instructions of the troubleshooting solution, a field engineer who wears the wearable electronic device can achieve troubleshooting of the specific machine rapidly and precisely, without needing to spend time finding the failure causes.

Abstract: A system for recognizing abnormal activity of human body using wearable electronic device and mixed reality technology, includes a first wearable electronic device, a plurality of second wearable electronic devices, at least one camera, and a judgement module. The system is suitable to be applied in any type of work environment, so as to monitor and determine whether a user (i.e., an operator or an employee) exhibits abnormal activities by referring a document of standard operating procedures (SOP), an operating manual and a document of safety operation standard (SOS), to reduce a rate of user mishandling, thereby achieving the enhancement of work efficiency and productivity.
