A training assistance apparatus includes an actual operation time acquiring unit configured to acquire an actual operation time of an operation that is executed by an operator on a processing machine, a standard time storing unit configured to store a standard time of the operation, and a display unit configured to display the actual operation time and the standard time for comparison.

An apparatus is provided that measures usage of a motor unit having a motor and a motor cable leading to the motor to provide operational power to the motor. The apparatus includes a housing that attaches to the motor cable such that the motor cable passes through an interior region of the housing. A sensor is situated in the interior region of the housing and is operable to sense current that flows in the motor cable. The apparatus has a counter that logs accumulated time of operation of the motor based on an amount of time that current is sensed by the sensor to be flowing in the motor cable.

Included are embodiments of a system for monitoring device usage. The system may include a handheld device for performing an action, where the handheld device includes an engagement sensor and a computer that includes a processor and a memory component. The memory component stores logic that causes the computer to determine a minimum device engagement time of the handheld device. In some embodiments, the logic causes the computer to receive output data from the engagement sensor, where the output data includes an actual device engagement time, determine if the actual device engagement time is at least as long as the minimum device engagement time, and in response to determining that the actual device engagement time is at least as long as the minimum device engagement time, determine the action taken by the handheld device.

A system, method and computer program product for controlling the operation of a door (1) to a room, the method comprising (S1) obtaining at least a first air pressure data (1ap) based on an air pressure on the inside of the door (1), (S2) obtaining at least a second air pressure data (2ap) based on the air pressure on the outside of the door (1), and (S5) determining at least a first air pressure difference data (1apdd) based on the difference between the at least first air pressure data (1ap) and the at least second air pressure data (2ap), and in a determination that the at least first air pressure difference data (1apdd) is outside of a predefined value, or a predefined value interval, generate a control signal (CS) for controlling the operation of the door (1).
