The definition and application of software and hardware patterns have been a major and very positive development in the field of computer engineering, in tandem with the deployment of agile and process architecture methodologies. In this article, we show how five time-triggered, real time system patterns developed by Michael J. Pont can be effectively employed to architect a low power, low cost flight controller. We adopt and apply Pont’s powerful pattern language for our research. The target platform is an ultra-light aircraft with tight constraints on mass and volume of any control hardware. Ultra-light in this context means that the aircraft has only one seat; weighs less than 254 pounds (115 kg) empty weight; has a maximum fuel capacity of 5 U.S. gallons (19 L); and has a top speed of 55 knots (102 km/h; 63 mph) calibrated airspeed at full power in level flight. We utilize the reliable Infineon C515C microcontroller, a member of the classic 8051 family of controllers for the hardware platform. This research makes a contribution to the engineering cybernetic issues of human-machine interface and control of an ultra-light aircraft.

| [14] | According to the IEEE specifications, “photodiodes are a two-electrode, radiation-sensitive junction formed in a semiconductor material in which the reverse current varies with illumination. Photodiodes are used for the detection of optical power and for the conversion of optical power to electrical power. Photodiodes can be PN, PIN, or avalanche. PN photodiodes feature a two-electrode, radiation-sensitive PN junction formed in a semiconductor material in which the reverse current varies with illumination. PIN photodiodes are diodes with a large intrinsic region sandwiched between P-doped and N-doped semiconducting regions. Photons absorbed in this region create electron-hole pairs that are then separated by an electric field, thus generating an electric current in a load circuit. Avalanche photodiodes are devices that utilize avalanche multiplication of photocurrent by means of hole-electrons created by absorbed photons. When the device's reverse-bias voltage nears breakdown level, the hole-electron pairs collide with ions to create additional hole-electron pairs, thus achieving a signal gain.” “Photodiodes Information,” IEEE GlobalSpec Engineering 360, accessed April 29, 2019, https://www.globalspec.com/learnmore/optics_optical_components/optoelectronics/photodiodes. |
