    摘要： A device to induce rotation of aircraft landing wheels is disclosed, using only the force of oncoming air to bring them up to synchronous ground (landing) speed during approach to landing. A complete, independently operating system with its own sensors, microcontroller, motors and control linkages, which does not interface with any of the aircraft's instumentation or systems, continually measures the actual ground speed of the aircraft during final approach, transmitting this flow of data to a microcontroller for continuous translation into required RPM for each tire diameter and monitors the precise RPM of each landing wheel through non-contact photo-tachometers whose outputs are multiplexed into the microcontroller. The system provides continuous control over the RPM of each landing wheel through air intake ducts with servo motor driven inlet vanes gating incoming air to the wheel-mounted impellers. An independent servo control loop for each wheel have their error signal and null point derived, through comparator logic and multiplexing, from the difference between instantaneous wheel RPM and ground-speed-based target RPM.

    摘要翻译： 公开了一种用于引导飞机着陆轮的旋转的装置，其仅使用迎面而来的力使其在着陆期间达到同步地面（着陆）速度。 一个完整的独立操作系统，其自身的传感器，微控制器，电动机和控制联动装置与任何飞机的装置或系统不相接触，在最终进场期间持续测量飞机的实际地面速度，将此数据传输到 一个用于每个轮胎直径连续转换成所需RPM的微控制器，并通过其输出被复用到微控制器中的非接触式光电转换器监测每个着陆轮的精确转速。 该系统通过进气管道连续控制每个着陆轮的RPM，其中伺服电动机驱动的入口叶片将进入的空气控制到车轮安装的叶轮。 每个车轮的独立伺服控制回路的误差信号和零点通过比较器逻辑和多路复用，从瞬时轮转速和基于地面速度的目标转速之间的差异得出。

    摘要： Cycling apparatus including pivoting handlebars that permit a rider to move the handlebars into either a drop or aerodynamic riding position, or any comfortable riding position therebetween. The apparatus comprises a cycle having a body, a housing is coupled to the body, and first and second handlebars are provided that are used to steer the cycle. Rotating apparatus is coupled to the housing and to the first and second handlebars for rotating the handlebars in unison. The handlebars are rotated between a first position wherein the handlebars are generally orthogonal to the body of the cycle and a second position wherein the handlebars are generally aligned with the the body of the cycle. The rotating apparatus may comprise first and second interlocking gears, a flexible drive coupling, a set of universal joints, or any similar rotating device that permits the handlebars to rotate between the desired positions. First and second brake levers are disposed adjacent respective distal ends of the first and second handlebars adjacent a rider's hand positions. First and second gear shift levers are also disposed adjacent respective distal ends of the handlebars adjacent the rider's hand positions. Forearm pads may be disposed on a portion of the cycle to which the housing is attached. The pivoting handlebars pivot in unison to permit different riding positions while the cycle is in motion.
