  • Receiver and transmitter for a network having a non-centralized medium access control
    Patent number: 7848706
    Abstract: A receiver includes a receiving unit for scanning a dedicated signaling channel for the presence of an announcement signal. The announcement signal indicates a transmitter willing to access a transmission medium. The receiving unit is further operative to receive a data signal from a further transmitter on a dedicated traffic channel. Furthermore, the receiver includes an interference estimator for estimating, whether an interference caused by a new transmitter is allowable or not. A processor is provided for applying an interference counter-measure, when the interference is not allowable. A transmitter can, without any limitation, transmit the announcement signal. The transmitter will start transmitting, when it receives a ready-to-receive signal from the addressed receiver and when it does not receive an objection tone from another receiver in the network.

  • Device for an electrical machine
    Patent number: 7315105
    Abstract: A device for axially magnetized electrical machines, especially motors, having a rotor with permanent magnets and a stator with a series of windings on iron cores. The stator comprises a support pin (17), which is integrated or joined with a protruding flange (20), which works as a support for cores (21, 22) with and without windings, which forms teeth. There are at least between some of the cores (21, 22) arranged support elements (25), which are fixed to the hub (18) of the stator.
