Abstract: Embodiments of the present invention pertain to maintaining an acceptable level of relative humidity inside of a disk drive. According to one embodiment, clean dry air is blow over a cover of the disk drive. The cover includes an unsealed servo write slot. The amount of clean dry air blown over the cover is regulated while a servo write process is performed so that a portion of the clean dry air is introduced into the disk drive.

Abstract: To enable a vehicle which can automatically track a substantially straight guidewire or the like at high speeds with prescribed dynamic characteristics to also track distinct guidewire curves with similar characteristics, an added signal which is a function of guidewire curvature and vehicle wheelbase is superimposed on the command signal derived from a tracking sensor to modify the command signal applied to a steering servo or other steering means while the vehicle negotiates a curve.

Abstract: A ground vehicle guidance system for following a current-carrying guidewire provides improved steering stability over a wide range of speeds and improved immunity to inductive field anomalies by computing vehicle heading and lateral displacement using sensor signals themselves substantially insensitive to heading variations, with the sensor signals being processed to provide steering command signals having specified relationships to vehicle steering geometry, so that desired damping factors can be obtained for both forward and reverse travel. Improved vehicle speed-limiting and stopping circuits control truck operation in accordance with computed heading and lateral displacement deviations independently from each other. Steering systems are illustrated both for vehicles using steerable wheels and vehicles steered by differential drive wheel speed control.

Abstract: A system for registering images produced by projectors on a screen or other viewing surface is described herein. Two or more projectors are used with a laser attached to one of the projectors. The laser emits a reference point on the screen and a light-sensitive sensor such as a diode array or TV camera is connected to the other projector to allow a determination of the reference point. One motion system is connected to one of the projectors and the laser and another motion system is connected to the other projector and the sensor. A computer is coupled to both motion systems, the laser and the sensor so that the computer will cause the projectors to move so that the images produced by the projectors are always registered and are believable to an observer.
