Abstract: A method is disclosed for operating a synchronous space division multiple access, code division multiple access communications system, as is a system that operates in accordance with the method. The method operates, within a coverage area of a base station (BS), to assign the same spreading code to a plurality of subscriber stations (SSs; to despread a plurality of received signals with a plurality of despreaders and to spatial filtering the plurality of despread received signals. The step of spatial filtering uses complex multiply operations performed at the symbol rate of the received signal. An antenna array has M-elements (M>1), wherein individual ones of P orthogonal spreading codes are reused &agr;M times within the coverage area, where 1/M<&agr;≦1.

Abstract: A method for positioning actuators inside printing machines is described. In particular, the positioning operations of metering elements, which serve to feed ink, moisture or varnish and interact with a rotating cylinder, are improved. To this end, the metering elements are automatically moved from time to time up to the rotating cylinder and the position resulting in the process is stored as a so-called zero position. The method according to the invention is intended in particular to ensure that the metering element is not set with too high a force relative to the cylinder during future positioning operations. This is done by motion commands being fed to the drive allocated to the metering element so that this drive moves the metering element in two areas, in which the metering element is contiguous to the cylinder and furthermore is in contact with the cylinder.

Abstract: The invention relates to a method and device for detecting ink or lacquer films on metallic surfaces inside printing machines. In particular, to irradiate the surface with light and sensing of the intensity of the reflected light to detect whether an ink film or lacquer film on a roller has been completely removed by applying a metering element or doctor-blade element. This is achieved according to the invention by the irradiation of the metallic surface or of the film located thereon, and the reception of the light reflected from the surface or the film located thereon is performed at the Brewster angle with respect to the surface normal, the Brewster angle being defined by the refractive index of the material of the film to be determined and that liner polarization of the light is performed at least partially in the plane of incidence, at least in one of the two beam paths.

Abstract: A connecting system for making electrical connections between a multiple conductor cable and a printed circuit board. A plurality of connector pins is mounted in a regularly spaced array on the printed circuit board and projecting above a first surface of the board. No other elements are mounted on the printed circuit board which are dedicated solely to the connecting system. Instead, a plurality of electrical components which are mounted on the circuit board for performing circuit functions, are mechanically positioned to surround the pins to provide an internal periphery of predetermined size, shape, and keyed configuration. The keyed periphery closely matches the outer periphery of a connector body attached to the cable. Thus, the electrical components on the circuit board key the connector body to the circuit board such that misplugging is avoided.

Abstract: A control system for a printing press in which a central computer is interfaced to a plurality of printing units through peripheral units located near the press units. The central unit utilizes digital signals to address particular peripheral units and to select control functions at the selected peripheral unit. The controlled functions in the press units provide analog feedback signals which are to be sensed by the central computer. A multi-function bus comprising both analog and digital sections couples the central computer to the peripheral units. The integrity of the analog feedback signals on the bus is maintained by assuring that the digital signals on the bus are maintained in a quasi-steady condition during intervals when the central computer is evaluating analog feedback signals on the analog section of the bus.
