摘要： A bus system for configuring communication interfaces in a vehicle has at least two different bus lines which are each electrically coupled to one and the same first voltage-limiting element to limit the voltage level of a voltage pulse occurring with a predefined reference potential as a positive voltage pulse between one of the two bus lines and a first point. In addition, the two bus lines are each electrically coupled to one and the same second voltage-limiting element to limit the voltage level of a voltage pulse occurring with a predefined reference potential as a negative voltage pulse between one of the two bus lines and a second point, to a second voltage limit.

摘要： A method for dynamically adjusting transmit power is disclosed, including: acquiring strength of a signal received by a receiver of a first system; determining whether the acquired strength is less than a sensitivity of the receiver corresponding to strength of a signal currently transmitted by a transmitter, based on correspondence information of strength of signals transmitted by the transmitter and sensitivities of the receiver, and the strength of the currently transmitted signal; if yes, then decreasing the strength of the currently transmitted signal to be equal to or less than the strength of a signal transmitted by the transmitter corresponding to a sensitivity of the receiver being regarded as the strength of the received signal. Corresponding control device and communication system are also provided. The manufacture cost of the device is reduced by the present invention. Meanwhile, better performance can be kept for the receiver.

摘要： In this invention, a test system includes a tester and a switching module for connecting any pin to the tester for testing a device-under-test (DUT), the test system has a rectifying device between the ground of the DUT and the ground of the switching module in order to isolate the DUT from the switching module, thereby blocking unwanted current flowing between the DUT and the switching module to ensure the correctness of the testing.Since the ground of the switching module is not directly connected to the ground of the DUT and the tester, the rectifying device will keep the voltage difference between the ground of the switching module and the DUT in a range between zero and the cut-in voltage of the rectifying device, thereby allowing single-ended signals to be used between the switching module and the tester or the DUT.

摘要： Systems and methods for full-duplex communication in a communications network, including generating a combined channel matrix including two or more channel matrices and determining a null space and a basis for the combined channel matrix. Common, individual, and disjoint vector spaces are determined, and common vector space is determined for each of one or more receiving nodes and each or one or more transmitting nodes, disjoint vector spaces for each of the one or more nodes are determined based on the common vector space for each of the one or more nodes, and individual vector spaces are determined based on the common and the disjoint vector spaces. Signals are mapped at each of the nodes to determine corresponding vector spaces; and interference alignment is performed in common vector spaces and zero forcing in disjoint vector spaces using a hardware processor.
