Abstract: A method of controlling the motion of a moveable door includes determining the direction that the door is moving with respect to its anticipated closed position, and based on the direction, regulating an amount of force that is available to the door for its motion. The method may further include monitoring the position of the door as it is moving, and adjusting the motion of the door and regulating the amount of force available to the door for its motion, based on the calculated difference between the door's position as detected during monitoring and its expected position.

Abstract: A lubrication system is provided for delivering coherent packets of a lubricant to a cutting surface of a machine tool. The system includes a nozzle for delivering a coherent packet of lubricant to the cutting surface, a pump for providing the lubricant to the nozzle via a supply line, and a controller configured to control the pump to provide the nozzle with a desired volume of lubricant. The coherent packet of lubricant has a volume substantially equal to the desired volume provided by the pump. The nozzle may be movable, and the controller may be configured to position and orient the movable nozzle. The controller may be an integrated controller configured to control both the operation of the lubrication system and the operation of the machine tool.
