Abstract: A system for providing wireless telecommunications access is presented. The system includes a wireline assembly that provides access to a telecommunications system for one or more wireline subscribers. The system also includes a wireless assembly that provides access to a telecommunications system for one or more wireless subscribers. A common control and switching system is connected to the wireline assembly, the wireless assembly, and a switched network. The common control and switching assembly establishes telecommunications channels between the wireline assembly, the wireless assembly, and the switched network, and controls the telecommunications channels.

Abstract: A pitching practice apparatus includes a frontal mechanical strike zone target at which the pitcher aims the ball and which contains yielding elements enabling the ball to pass rearwardly through a photoelectric sensing plane having sensing beams on two orthogonal axes. Behind the photoelectric sensing arrangement which precisely locates the position of the ball in the strike zone horizontally and vertically is a spring-mounted ball return panel against which the pitched ball impinges and is returned to the pitcher by rebounding from the panel. A ball return trough forming the floor of the apparatus extends between the ball return panel and the frontal strike zone target.

Abstract: In combination with a charged particle beam generator and accelerator, apparatus and method are provided for stabilizing a beam of electrically charged particles. A guiding means, disposed within the particle beam, has an electric charge induced upon it by the charged particle beam. Because the sign of the electric charge on the guiding means and the sign of the particle beam are opposite, the particles are attracted toward and cluster around the guiding means to thereby stabilize the particle beam as it travels.
