Abstract: A ball delivery device, system, and method housing a plurality of balls for a game session is presented. The ball delivery device includes a mixing chamber that receives the plurality of balls for the game session, a mixing arm (or arms) that mixes the plurality of balls within the mixing chamber during the game session, a ball holder disposed on the arm, wherein the ball holder captures a single ball from the mixing chamber during the game session and deposits the ball on a reading platform, an agitator mechanically coupled to the reading platform, wherein the agitator induces a vibration in the reading platform, a reader that scans an identifier printed on the ball as the ball rotates on the vibrating reading platform, and a camera that captures an image of the ball.

Abstract: A ball delivery device, system, and method housing a plurality of balls for a game session is presented. The ball delivery device includes a mixing chamber, at least one instruction to start the game session, an identifier, at least one arm, a ball holder, a reader and a tube. The mixing chamber receives the balls for the game session. After receiving an instruction to begin the game session, balls are singly drawn from the mixing chamber. The identifier disposed on each ball uniquely identifies each ball. The arm mixes the balls in the mixing chamber. The ball holder disposed on the arm holds a single ball that is randomly selected from the mixing chamber. The reader reads the identifier of the ball selected by the ball holder. The tube receives each selected ball and holds the selected balls after the identifier reads the ball and until completion of the game session.

Abstract: An apparatus for testing magnetic heads that interact with magnetic disks includes a translational slide and a rotatable arm mounted to one end of the slide. The translational slide moves the rotatable arm in a longitudinal direction parallel to the surface of a magnetic disk. The arm rotates the magnetic head to different positions relative to data tracks on the disk. A second translational slide moves the magnetic head vertically above the disk to adjust the vertical position of the head. The three movements of the head, (1)horizontally across the disk, (2)rotationally by the arm, and (3)vertically relative to the disk surface are controlled by servomechanisms. A read/write amplifier circuit is connected to the head under test. The test apparatus is controlled by a computer that interfaces with circuitry connected to the servomechanisms.
