摘要： In general, in one aspect, the disclosure describes a method that includes selecting an offset between start of communications of a first radio in a multi-radio platform (MRP) and start of communications of a second radio in the MRP. Synchronizing clocks of the fist radio and the second radio to maintain the offset. Determining safe zones within the communications of the second radio based on configuration of the first radio and the second radio and the selected offset. The safe zones are locations that minimize conflicts between receiving operations of the first radio that are at fixed locations and transmitting operations of the second radio and transmitting operations of the first radio that are at fixed locations and receiving operations of the second radio.

摘要： A network includes a TCP-in-TCP tunnel between a mobile device, which includes a TCP client and a gateway, and a TCP server, which resides in a subnet. Another gateway in the subnet receives and caches TCP packets and acknowledgments (ACKs) from the TCP-in-TCP tunnel. In response to receiving an indication from the TCP server that it has not received a cached TCP packet, the second gateway may resend the packet without relaying the indication to the TCP client, and the first gateway may send a control message instead of a complete TCP packet to the second gateway.

摘要： Systems and methods provide for controlling contention in a wireless network device. The systems and methods transmit a packet on a wireless network. If the transmission is not successful, then a contention window parameter is adjusted according to a fast backoff operation. If the packet transmission was successful and the current value of the contention window parameter is less than a threshold value then the contention window parameter is decreased according to a contention avoidance operation. If the packet transmission is successful and the current value of the contention window parameter is greater than the threshold value then the contention window parameter is decreased according to a slow start operation.

摘要： A four-wheel drive electric vehicle is provided. The vehicle comprises a chassis and a power system. The power system comprises batteries, an electric motor, a DC-DC converter and an electric motor controller which are electrically connected, and the chassis comprises a frame, a transmission/transfer case, a drive shaft, a front axle assembly as well as a rear axle assembly. The transmission/transfer case, the front axle assembly and the rear axle assembly are mounted on the frame. The transmission/transfer case is connected with the rear axle assembly directly and with the front axle assembly via the drive shaft. Under the control of the electric motor controller, the electric motor is driven to rotate by the batteries, whereby a power is transferred from the motor to the transmission/transfer case, and a part of the power is transferred to the rear axle assembly with the other part transferred to the front axle assembly via the drive shaft.
