| 20100304589 | Miniature switch connector - The invention relates to a Switch connector for mounting on a printed circuit board, adapted to receive a mating connector in an insertion direction along an insertion axis. The switch connector comprises a shield, a contact element, and a contact spring having at least one fixed leg, at least one elastically deflectable switching leg, and at least one spring bend, the fixed leg and the switching leg extending from the spring bend in a common direction and passing the insertion axis. The switching leg is adapted to be moved by insertion of the mating connector from a rest position, at which the switching leg exerts a spring force onto the contact element, to a switching position, at which the switching leg is spaced apart from the contact element, at least one spring force flux that in the rest position is generated by the switching leg and guided in a closed loop to the fixed leg. To increase the reliability of the switching function, the shield is arranged in the closed loop of the spring force flux. | 12-02-2010 |

| 20100164498 | INTEGRATED-CIRCUIT LOW-NOISE AMPLIFIER - It is proposed herein to improve the specifications of a low-noise amplifier (LNA) by integrating it in a chip. In order to cover a range of operating frequencies using a single chip, the integrated-circuit amplifier proposed herein comprises an input port configured to receive a magnetic resonance (MR) signal from a radio-frequency (RF) coil, one or more LNAs configured to amplify the received MR signal, and an output port configured to output the amplified MR signal from the one or more LNAs. The operating frequency of the RF coil depends on the field strength, The matching circuit, if present, needs to be tuned to operate at the operating frequency of the RF coil, and depends on the component values in the loop, thus on loop size. In contrast, the proposed integrated-circuit amplifier is capable of directly connecting to RF coils with different loop sizes, without the need for a matching circuit. | 07-01-2010 |

| 20110103950 | SYSTEM AND METHOD FOR PROVIDING A CONTROLLED FLOW OF FLUID TO OR FROM A WIND TURBINE BLADE SURFACE - A wind turbine blade system having a blade rotatably attached to a rotor of a wind turbine. The system further includes a controller and one or more openings disposed along at least one surface of the blade and a fluid moving device arranged and disposed to provide a fluid to or from the one or more openings. A controlled amount of the fluid is provided to the one or more openings. The amount of fluid is determined by the controller. A wind turbine and a method for operating a wind turbine are also disclosed. | 05-05-2011 |
