20090229931 | HYDRAULIC VEHICLE BRAKE SYSTEM - The invention proposes equipping a hydraulic vehicle brake system with a pedal travel modulator that has an electromechanically driven piston-cylinder unit. The piston-cylinder unit upon brake actuation “furnishes” additional brake fluid and thereby boosts a pedal travel of the vehicle brake system. | 09-17-2009 |
20100126167 | ELECTROMECHANICAL BRAKE BOOSTER - The invention relates to an electromechanical brake booster for a master brake cylinder of a hydraulic vehicle braking system. The invention provides to configure the brake booster such that it preferably includes a switchable freewheel, which enables an actuation of the master brake cylinder without any movement of the electric motor of the brake booster. The invention further provides to configure the brake booster such that it includes a mechanical gear having a variable transmission ratio, which has a high path transmission at the beginning of an actuation of the master brake cylinder, and a force transmission that rises with increasing actuation. A variable gear ratio is possible using a rack and pinion gear, the toothed rack of which has a soothing with a pitch that changes across the length of the toothed rack. A further possibility of a mechanical gear having a variable ratio is a toggle lever mechanism. | 05-27-2010 |
20100198473 | BRAKE SYSTEM FOR A VEHICLE AND A METHOD FOR OPERATING A BRAKE SYSTEM FOR A VEHICLE - A brake system for a vehicle having a sensor device for providing a first and second sensor signal, a first and a second brake control device, which are directly connected to the sensor device and to provide a corresponding control signal for the first and/or second sensor signal, and a first and a second signal line for transmitting the control signal, the first signal line directly connecting the first brake control device to a first and second wheel actuator device and the second signal line directly connecting the second brake control device to a third and fourth wheel actuator device, the four wheel actuator devices exerting a braking torque corresponding to the control signal on the associated wheel, and the first wheel actuator device being directly connected to the second brake control device and/or the sensor device. A method for operating a brake system for a vehicle is also provided. | 08-05-2010 |

20090052398 | METHOD OF PERFORMING A HANDOVER - The invention concerns a method of performing a handover ( | 02-26-2009 |
20090103499 | BEACON AND MOBILE TERMINAL SYNCHRONIZATION AND METHOD THEREOF - The invention relates to a method of optimizing measurement duration in a telecommunications network, said telecommunications network comprising a first base station connected to a first radio network, at least a second base station connected to a second radio network, a core network connected to said first and second radio network, a database coupled to said core network, said method comprising: sending a first beacon period information belonging to said first base station from said first base station to said database; sending at least a second beacon period information belonging to said second base station from said second base station to said database; storing at least said first and second beacon period information on said database; sending a request of said second beacon period information from said first base station to said database; generating a response of said second beacon period information belonging to said second base station from said database to said first base station; forwarding said response of said first base station to said mobile terminal; adjusting measurement periods on the mobile terminal based on said response of said beacon period information. | 04-23-2009 |
20090137214 | USER TERMINAL FOR RADIO COMMUNICATIONS, AND METHOD OF OPERATION THEREOF - A method is provided of operation of a user terminal in a network for radio communications comprising a first radio access network and a second radio access network. The user terminal comprising a first radio, a second radio, a first antenna and a second antenna. The first radio comprises two ports for connection to antennas. At least one of the two antennas is switchably connectable to each of the radios. The method comprising the following steps: connecting the two antennas to the first radio such that each port is connected to a respective antenna, and receiving data at the first radio passed via a radio communication connection from a first radio access network to the two antennas; switching the second antenna from connection to the first radio to connection to the second radio, receiving data at the first radio passed via a radio communication connection from the first radio access network to the first antenna, and receiving data at the second radio passed via a radio communication connection from a second radio access network to the second antenna. | 05-28-2009 |
20100002651 | HANDOVER METHOD AND APPARATUS IN A WIRELESS TELECOMMUNICATIONS NETWORK - A wireless telecommunications network may include parts that operate at different packet transfer delays, so that a mobile terminal undergoing handover from one node to another experiences different delays before and after handover. An additional delay is applied during the handover process to packets sent to the mobile terminal via the node at the smaller delay so as to reduce the difference between the two delays. The additional delay may be applied at an anchor node connecting parts of the wireless network of different radio access technology types or at other parts of the network. Information regarding packet transfer delays may stored and accessed to determine the delays for nodes involved in handover and/or obtained by measurements made during a call, for example. | 01-07-2010 |
