An air flow hour meter is provided. The air flow hour meter includes a passage configured to receive a pressurized fluid flow therethrough. An obstruction in the passage can be positioned in the fluid flow. A sensor in communication with the fluid flow can be configured to measure a pressure differential of the fluid flow between a first point and a second point of the passage. A microprocessor can be configured to calculate the signal-to-noise ratio of the sensor, and a timer can be configured to activate when the signal-to-noise ratio falls below a predetermined limit and otherwise deactivate.

A compliance monitoring system (40) for an intraoral appliance comprises a power source (460), a detector (410) for detecting when the intraoral appliance is positioned in the mouth for use, a recorder (430) configured to record measurement data, and a transponder (440) configured to communicate the measurement data. The monitoring system is adjustable based on a particular property of a patient or a group of patients.

A device maintenance apparatus has a display, in which the display displays a first screen generated based on first device information of a maintenance-target device, a second screen generated based on second device information of the device, and a third screen generated based on the first device information and the second device information.

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.

The invention relates to a testing device (4) for testing a tamping unit (1) comprising two oppositely positioned vibratable tamping tine arms (7) which are movable towards one another, wherein the testing device (4) comprises a separate clamping device (5) in each case for clamping the two tamping tine arms (7), and wherein the two clamping devices (5) are connected to a linear drive- and measuring device (9) for recording force-path curves. A testing device (4) of this kind enables the quality testing of a tamping unit (1).
