  • Patent number: 9068233
    Abstract: The invention relates to methods and compositions for identifying soybean plants that are tolerant, have improved tolerance or are susceptible to Fusarium solani infection (the causative agent of sudden death syndrome or SDS). The methods use molecular genetic markers to identify, select and/or construct disease-tolerant plants or identify and counter-select disease-susceptible plants. Soybean plants that display tolerance or improved tolerance to Fusarium solani infection that are generated by the methods of the invention are also a feature of the invention.

  • Patent number: 9059277
    Abstract: A radio frequency (RF) laterally diffused metal oxide semiconductor (LDMOS) device is disclosed, wherein a lightly doped n-type drain region has a laterally non-uniform n-type dopant concentration distribution, which is achieved by forming a moderately n-type doped region, having a higher doping concentration and a greater depth than the rest portion of the lightly doped n-type drain region, in a portion of the lightly n-type doped region proximate to the polysilicon gate. The structure enables the RF LDMOS device of the present invention to have both a high breakdown voltage and a significantly reduced on-resistance. A method of fabricating such a RF LDMOS device is also disclosed.

  • Patent number: 9037077
    Abstract: A relay method and device, wherein the control signal and the data signal which are in the same subframe are directly sent to a lower level device respectively by an upper level device and a relay function device. In one example, the relay function device transmits data signal using subscriber special reference signal to make the lower level device estimate an access channel correctly; in another example, the relay function device carries out precoding of the data signal correlative with the access channel so as to cancel the influence of the access channel, thereby make the lower level device receive data signal correctly. Retransmission control signaling is sent to the lower level device in each subframe by the upper level device to ensure the fixed sequential relationship of feedback retransmission.

  • Publication number: 20150078248
    Abstract: The present invention discloses methods for supporting coexistence of a mobile relay and a fixed relay in a wireless communication network, and corresponding apparatuses. A method comprises: receiving, by a base station, a first message from a relay; determining, by the base station, whether the relay is a mobile relay or a fixed relay based on the first message received from the relay; sending, by the base station, a second message to a mobility management entity, the second message comprising information indicating whether the relay is a mobile relay or a fixed relay so that the mobility management entity can select a corresponding service gateway SGW and a corresponding packet data network gateway PGW for the relay. According to the present invention, coexistence of a mobile relay and a fixed relay in a wireless communication network can be realized with a minimal impact on standardization work.

  • Publication number: 20150049792
    Abstract: In a time-reversal wireless system, a transceiver receives a combined signal that includes signals from a plurality of devices, each device sending a signal to the transceiver through multiple wireless propagation paths. Signals sent from each of the devices are estimated based on the combined signal and a signature waveform associated with the device. Interference associated with the estimated signal from each of the devices is determined based on the estimated signals from the devices. The signal sent from each of the devices is determined by subtracting the interference associated with the estimated signal associated with the device from the estimated signal associated with the device.
