20090153468 | Virtual Interface System - The invention relates to a virtual interface system, to a method of providing a virtual interface, and to a data storage medium having stored thereon computer code means for instructing a computer system to execute a method of providing a virtual interface. A virtual interface system comprises a camera; a processor coupled to the camera for receiving and processing video data representing a video feed captured by the camera; a display coupled to the processor and the camera for displaying first and second interface elements superimposed with the video feed from the camera in response to display data from the processor, the second interface element being displayed at a fixed location on the display; wherein the processor tracks a motion action of a user based on the video data received from the camera, controls a display location of the first interface element on the display based on the tracked motion action; and determines a user input based on a relative position of the first and second interface elements on the display. | 06-18-2009 |

20090190697 | DECODING TECHNIQUES FOR MULTI-ANTENNA SYSTEMS - In one embodiment, a wireless device for a wireless data communication system including the wireless device and a base station. The base station includes a plurality of first groups and a signal-processing unit. Each first group includes a receiver and at least one antenna connected to the receiver. The signal-processing unit includes memory and a processor adapted to process signals received by the first groups using a Maximum Likelihood Detection (MLD) method. The wireless device includes a plurality of second groups, each second group adapted to transmit a wireless signal to at least one first group via a corresponding communication channel. Each second group further includes a transmitter and at least one antenna connected to the transmitter. The signal-processing unit is adapted to store, in the memory, information corresponding to one or more transfer functions, each transfer function corresponding to transmission of a wireless signal from an antenna of the second groups to an antenna of the first groups. The transmitters and receivers are adapted to operate at essentially the same frequency or frequency band. Two or more of the communication channels are generated simultaneously. Each transmitter is adapted to modulate an information signal on a radio-frequency signal according to a Quadrature Amplitude Modulation (QAM) method to transmit QAM symbols. Each receiver is adapted to demodulate information signals from a received radio-frequency signal according to the QAM method. | 07-30-2009 |
20090274237 | BEAMFORMING TECHNIQUES FOR MIMO COMMUNICATION SYSTEMS - Improved beamforming techniques are provided for use in MIMO (multiple-input, multiple-output) communication systems, including MIMO-OFDM systems. The techniques include: (1) determining beamforming (BF) weights using a smoothed singular value decomposition (SVD) of the channel matrix; (2) determining BF weights using a power-optimized minimum mean-square error (MMSE) technique when the number of available transmit antennas exceeds the number of signal streams; and (3) determining BF weights using a hybrid SVD-MMSE technique. Additional techniques for reducing the impulse response length of the BF weights and/or normalizing the power per transmit antenna or per data stream may be used in conjunction with these or other beamforming techniques. | 11-05-2009 |

20110103108 | Converter Valve - A converter valve unit including a plurality of parallel connected semiconducting elements, a free-wheeling diode and a control unit. | 05-05-2011 |
20140313796 | CONVERTER VALVE - A converter valve unit including a plurality of parallel connected controllable semiconducting elements. A free-wheeling diode is connected in anti-parallel with each semiconducting element. A control unit is configured to control each semiconducting element. A current sensor is connected to each of the parallel connected semiconducting elements. The current sensor is configured to sense a current of each semiconducting element by measuring a voltage over the current sensor. A differentiator is configured to compare the currents of the semiconducting elements by comparing the voltages. Upon detecting an unbalance in the currents the differentiator sends a turn-on signal to all control units to control all the semiconducting elements of the valve unit into a conducting stage. | 10-23-2014 |

20090277431 | Internal combustion engine with an exhaust-gas recirculation and method for operating an internal combustion engine - An internal combustion engine has a high-pressure exhaust-gas recirculation line and a low-pressure exhaust-gas recirculation line with a low-pressure exhaust-gas recirculation valve. The low-pressure exhaust-gas recirculation line branches off from the exhaust-gas system downstream of a turbine of an exhaust-gas turbocharger and opens into a fresh-air system upstream of a compressor of the exhaust-gas turbocharger. An exhaust-gas flap is disposed in the exhaust-gas system downstream from where the low-pressure exhaust-gas recirculation line branches off from the exhaust-gas system. At least one pressure sensor is disposed in the low-pressure exhaust-gas recirculation line and configured such that the at least one pressure sensor determines a pressure difference in the low-pressure exhaust-gas recirculation line between a point upstream of the low-pressure exhaust-gas recirculation valve and a point downstream of the low-pressure exhaust-gas recirculation valve. A method for operating an internal combustion engine is also provided. | 11-12-2009 |
