Publication number: 20240048243Abstract: Apparatus including an optical signal generator, a data transmission path, and an optical signal receiver. Optical signal generator includes a coherent light source for generating a spectrum of carrier signals at different carrier frequencies, an optical demultiplexer that receives and separates the different carrier signals into separate optical paths, a pair of optical modulators located in each of the separate optical paths to modulate each different carrier signal with a data signal and produce an upper and lower sideband pair at each of the different carrier frequencies, and an optical interleaver to combine the upper and lower sideband pairs into an optical super-channel of interleaved sub-bands. Optical signal receiver includes a demodulator for extracting the data signals. Optical modulators are configured to reuse each carrier signal to transmit different data in each of the upper sideband and the lower sideband and increase the capacity of the super-channel. Also a method.Type: ApplicationFiled: December 17, 2021Publication date: February 8, 2024Applicant: MONASH UNIVERSITYInventors: William Peter Corcoran, Andreas Stefan Boes, Xingyuan Xu, Mengxi Tan, Chawaphon Prayoonyong, Arnan Deane Mitchell, David James Moss

Publication number: 20220386134Abstract: A method and a system with which a primary user, in particular a mobile radio operator, can make a part of the radio spectrum range which is reserved exclusively for the mobile radio operator available in localized and/or time-restricted fashion to a local end user who requested the restricted usage authorization of the radio spectrum range using registered credentials at the mobile radio operator. By way of the credentials the mobile radio operator can allow the local end user limited usage of that radio spectrum range in fee-bearing fashion and can bill same. The local user can then use the assigned frequency band in accordance with his own needs. In particular the user can wirelessly transmit signals in the assigned frequency range between end devices to which no credentials are allocated and in that situation use a transmission protocol which is not defined for the mobile radio network.Type: ApplicationFiled: August 10, 2022Publication date: December 1, 2022Applicant: Sennheiser electronic GmbH & Co.

Patent number: 8035837Abstract: A communications system, with a network, is usable to transmit at least image data to at least one illuminating device. The illustrating device illustrates a printed image location in a printing machine. A network is provided for the control and/or monitoring of the printing machine. A network for the communication of data to be processed in a pre-printing stage is also provided in that pre-printing stage, which prepares that image data. These two networks are connected to the same signal line or transmission link or are each constructed identically, with respect to their data transmission properties. The communications system, with the network, can control or monitor a printing machine having a number of sections, with at least two of these sections having a section controlling device. These section controlling devices are connected to the network, and control or monitor their respective sections. The network has the same data transmission properties in each of these sections.Type: GrantFiled: December 19, 2005Date of Patent: October 11, 2011Assignee: Koenig & Bauer AktiengellschaftInventors: Andreas Stefan Birkenfeld, Thomas Türke

Patent number: 8004706Abstract: A printed image is produced at least one printed image location using a printing machine with at least one illuminating device that produces at least one printed image at a number of printed image locations. These respective printed images belong to the same page of a printed product to be produced by the printing machine. This page of the printed product exists in the form of a file containing image data before it is produced as the printed image. That file contains image data of all of the printed images of the page of the printed product. A raster image processor is aligned with each printed image location and converts only image data of the printed images of the page of the printed product into raster data, with that printed image being assigned to a respective printed image position. A network is provided for use in the electronic communication of at least image data. Each raster image processor is connected to this network by an interface which receives data.Type: GrantFiled: December 19, 2005Date of Patent: August 23, 2011Assignee: Koenig & Bauer AktiengesellschaftInventors: Andreas Stefan Birkenfeld, Thomas Türke
