In a wireless control terminal configured to control a control target connected to a control apparatus by working in cooperation with a wireless assistant terminal capable of transmitting a predetermined control instruction for controlling the control target to the control apparatus by using a predetermined control wireless scheme with supply of power from a battery included in the wireless assistant terminal, a wireless control terminal-side battery is provided within the wireless control terminal so as to supply driving power required for control regarding emergency stop of the control target performed with a predetermined wireless scheme of the wireless control terminal. At least remaining storage power information regarding a remaining amount of storage power in the wireless control terminal-side battery is output to a notification apparatus provided in the wireless control terminal or the wireless assistant terminal.

A system and method are provided for a variable speed compressor with a control module that controls an operating frequency of the variable speed compressor. The control module stores a prohibited frequency range that includes a resonant frequency of the variable speed compressor and an allowed upper frequency above the prohibited frequency range and an allowed lower frequency below the prohibited frequency range. The control module determines a requested frequency and operates the variable speed compressor at the allowed upper frequency for an upper frequency operating time and at the allowed lower frequency for a lower frequency operating time when the requested frequency is within the prohibited frequency range. The control module determines the upper frequency operating time and the lower frequency operating time such that a time-averaged frequency output over the upper frequency operating time and the lower frequency operating time corresponds to the requested frequency.

Systems and methods for autonomous sterilization of vehicles includes coded logic or processing instructions to determine (i) when sterilization should occur (or not occur), (ii) where sterilization should occur (or not occur), and/or (iii) how sterilization should occur (e.g., which method to use, how long to conduct, and/or which parameter values/settings to employ). The sterilization system may autonomously determine when it is safe to sterilize an environment/location and/or how such sterilization should be carried out. Autonomous sterilization systems and/or processes described herein may permit facilities and/or services to remain open and/or available at higher rates than current offline processes permit, thereby increasing availability.

A virtual reality training system for industrial labor applications is disclosed. Users wear virtual reality equipment including a head mounted device and enter a virtual worksite replete with VR industrial equipment, VR hazards, and virtual tasks. Through the course of completing the tasks a plurality of sensors monitor the performance of the user or users and identify knowledge gaps and stresses of the user(s). The system generates an evaluation associated with the user(s) and then informs the user where there is room for improvement and informs an administrator of potential liabilities latent within evaluated employees.
