Abstract: A sprayer system including a wand, a rotary arm, a motor, a housing, a support, and a controller or control panel. The wand has a nozzle at one end. The rotary arm rotates around a first axle, and is connected at a distal end through a bearing to an opposite end of the wand. The housing covers or encloses a part of the wand, the rotary arm, and a rotatable ring through which the wand passes. The motor drives rotation of the rotary arm. The support mechanically supports the housing. The controller/control panel controls rotation of the rotary arm. The wand, the rotary arm and the ring are configured so that rotation of the rotary arm causes the nozzle to move in a circular, elliptical and/or oval pattern. Methods of making and using the sprayer system and software for controlling the system are also disclosed.

Abstract: A track map of a disk drive is generated to compensate for various conditions. A track map is a stored measurement of every “half” servo track width on a disk. Every servo half track width is measured in the factory on a disk and then the data is stored on the disk for use during drive operations. When an individual track is accessed, the appropriate servo half track width data is pulled from memory and is used to adjust a scale factor for that local half track width. The track map may be used to compensate for various conditions including varying servo track width, microjog distance, and data track spacing.
