Abstract: A system and computer-implemented method communicatively interfaces a Process Automation (PA) application executing on a mainframe computer with a mainframe automation function executing on the mainframe computer. The PA application executes within a services layer, which runs on top of a base Operating System (OS) layer of the mainframe computer. Some automation functions execute within the base OS layer, while other automation functions within the services layer. Therefore, an interface executing within the services layer determines which of the two disparate execution environments is needed to execute a given mainframe automation function, and invokes the function within the appropriate environment.

Abstract: A pickup assembly for stringed instruments such as guitars or the like, consists of a hollow cylindrical tube of magnetizable material in contact with a permanent magnet to produce an electro-magnetic field one upon each side of one free end of the cylinder and a resistive field coil in operative connection with the cylinder in a conventional manner. The vibrating string of the instrument passes diametrically over the open end of the pole piece cylinder spaced slightly above the surface thereof and between the two magnetic fields which are situated one upon each side of the longitudinal axis of the string. This permits free vibration of the string at all frequencies without any dampening or attenuation occurring.
