Abstract: Aspects of a system for holding workpieces in place during processing are described. In an example, the system includes a distribution manifold coupled to a vacuum source, and multiple linear valves coupled to the distribution manifold, where each linear valve has a manifold with multiple openings and is adjustable to select one or more of the multiple openings to have a path to the vacuum source through the distribution manifold for providing a vacuum to hold a workpiece in place. In another example, the system includes a vacuum holder having a first array of openings, a system of linear valves positioned below the vacuum holder and having a second array of openings that aligns with the first array of openings, and a vacuum source that provides vacuum for holding a workpiece on the vacuum holder. A method for holding workpieces in place during processing using these systems is also described.

Abstract: A dispenser or dispensing system. The dispenser can be a screw conveyor pill dispenser, tumbler pill dispenser, push-to-operate pill cap dispenser, twist-to-operate pill cap dispenser, or push-to-operate pill cap dispenser. The pill dispenser may include a pill dispenser control system that can interact with a personal device, such as a smart phone. The pill dispenser control system can implement communication with a personal device, pill identification, user identification and security, scheduling functions, and notifications. The pill dispenser can dispense pills manually, semi-automatically, or automatically.

Abstract: A wheel balancer has a spindle for mounting a wheel/tire assembly thereon, a motor for spinning the spindle about its longitudinal axis, and at least two sensors for sensing imbalance forces. A set of calibration coefficients for the wheel balancer are determined solely from the measurements made during a set of calibration spins and from knowledge of the amount of imbalance mounted to the rotating spindle during the calibration spins, without any knowledge or measurement of the relative geometry of the balancer. The set of calibration coefficients and other calibration data is stored in an electronic memory for subsequent use in balancing a wheel/tire assembly. During balancing, a wheel/tire assembly mounted on the spindle is spun and the corresponding output signals of the sensors are measured and recorded.
