  • Patent number: 7605046
    Abstract: The invention relates to an active matrix structure and method for manufacturing the active matrix structure for a display device, wherein the structure includes: providing a matrix substrate with a number of row lines and a number of column lines, with each point of intersection between one of the row lines and one of the column lines being assigned a passage through the matrix substrate for generating a pixel, depositing a layer of p-silicon on the matrix substrate, for each pixel, creating an n+-doped region in the p-silicon, which n+-doped region is provided from the passage as far as a free surface of the p-silicon layer, and creating a p+-doped region within the n+-doped region such that a layer of the n+-doped region remains, and applying a layer made of a matrix material which has particles of electronic ink contained therein, or an organic light-emitting diode layer on a free surface of the final structure resulting from step c).

  • Publication number: 20070025317
    Abstract: The invention provides that, in the event of a decentrally or centrally organized access to the transmission medium, preferably an IEEE 802.11 system, pilot signals are transmitted from the transmitter to the receiver, and the allocation table is subsequently calculated by the receiver on the basis of the received pilot symbols. The allocation table is transmitted from the receiver to the transmitter so that the subsequent data exchange can take place based on the allocation table.

  • Publication number: 20060140146
    Abstract: A method for controlling data circuits in order to transmit data via data circuits that are allocated to different applications in a local area network. The network includes at least two stations which are configured for transmitting data. At least one first transmission protocol is assigned to a data packet so as to transmit data that is segmented into data packets. The transmission times of the data packets are established in accordance with the assigned transmission protocols if at least one alternative second transmission protocol is provided.
