Abstract: An oscillating fan control system includes a holder, a stepper motor, a rotating shaft, a shaft encoder, and a controller. The controller is electrically coupled to the stepper motor and the shaft encoder. The shaft encoder can generate a status signal corresponding to a rotation path of the rotating shaft. The controller includes a reversing circuit and a driving circuit. The reversing circuit can generate a reversing signal for the stepper motor in response to the status signal indicating a deviation of the rotating shaft from a midpoint position of the rotation path. The driving circuit can generate pulse signals for the stepper motor according to a subdivision parameter and an oscillation angle. A method for controlling an oscillating fan is also disclosed.

Abstract: A monitoring system detects and measures a quantity of radical particles within a gas. A test chamber is coupled to a flow channel that transmits a gas. The test chamber defines an aperture connecting the test chamber and the flow channel, and the aperture permits a subset of the gas to enter the test chamber from the flow channel. An ionizer is positioned within the test chamber and generates radical ions from radical particles of the subset of the gas. A mass spectrometer measures a quantity of the radical ions, thereby providing a measurement of the radical particles in the gas.

Abstract: A data processing system for automating the process of managing flight data and generating reports based on that data. The system accesses flight data transmitted on an airborne databus, where the data represents sensor readings indicative of various flight parameters. The accessed flight data is sampled, filtered, decoded, encrypted, and subjected to an adaptive compression process prior to being stored on a portable, self-protected secure memory device. After the flight ends, the portable, self-protected secure memory device is transferred to ground personnel. The data stored on the memory device is then accessed by authorized personnel, decompressed and decrypted. The flight data is analyzed and used to evaluate pilot performance and monitor the operation of the aircraft through the generation of flight reports. Various data analysis techniques, including artificial intelligence based algorithms and expert systems may be used to examine the flight data and determine its significance.
