Abstract: A backplane testing system is provided. Based on the connection relationship and signal transfer relationship of a differential signal transceiver, a backplane and a loop device, the differential signal transceiver generates a set of pseudo random binary sequence (PRBS) as a differential signal, and sends the differential signal and receives the returned differential signal, and then determines whether the differential signals sent and received are the same; and the differential signal transceiver generates a test signal that conforms to the IEEE-1149.6 boundary scan test standard, and sends the test signal and receives the returned test signal through a second positive differential signal circuit and a second negative differential signal circuit, and then determines whether the test signals sent and received through the second positive differential signal circuit are the same and whether the test signals sent and received through the second negative differential signal circuit are the same.

Abstract: The present disclosure illustrates a shopping mall guiding system based on Internet of Things (IoT) and a method thereof is disclosed. Through IoT, shelves are positioned and product displaying messages thereof are transmitted. A server provides a shopping interface according to the product displaying messages, and after a mobile device logs into the shopping interface and creates an order list, the servers sieves out the shelves according to the order list and the product displaying messages and then generates a shopping route, a map and a product position message for displaying and guiding shopping. As a result, the system and method of the present disclosure may be helpful to improve the shopping convenience.

Abstract: A test circuit board adapted to be used on memory slot is provided. Each memory slot of a board to be tested is connected to one test circuit board. A plurality of the test circuit boards form an in-series connection therebetween. A test access port (TAP) controller is connected electrically to the board to be tested and one of the test circuit boards so that the memory slots, which are connected to the test circuit boards, may be tested at the same time.

Abstract: A test circuit board adapted to be used on SATA connector is provided. Two test circuit boards can be seriously connected with each other through a first JTAG connection interface and a second JTAG connection interface. Therefore, the efficiency of reducing TAPs of TAP controller and providing test signal coverage of all of test signals may be achieved.

Abstract: According to the inventive concept, there is provided a wind turbine with at least one blade. The wind turbine comprises a first accelerometer mounted at a first radial position of the blade and being adapted to determine a first acceleration value, and a second accelerometer mounted at a second radial position of the blade different from the first radial position, and the accelerometer being adapted to determine a second acceleration value. The wind turbine further comprises a controller adapted to generate a signal based on said first and second acceleration values. There is also provided a method for monitoring a blade of a wind turbine.

Abstract: A wind turbine installation monitoring device, for detecting relative movement between two adjacent components of a wind turbine installation is provided. The device comprises a deformable member together with securing means. The securing means is configured to enable the device to be connectable to a wind turbine installation, in use. The deformable member is located across an interface between the adjacent components of a wind turbine installation. Further, detection means are provided and are configured to detect deflection of the deformable member and thereby to detect relative movement between the two components.

Abstract: A load balancing method for network intrusion detection includes the following steps. Packets are received from a client. The data packets include a protocol type and a protocol property. An intrusion detection procedure is loaded on a receiving end. A corresponding request queue is set for each intrusion detection procedure. The request queue is used for storing the data packets. The data packets are processed a separation procedure, and are categorized into data packets of a chain type and data packets of a non-chain type according to the protocol type. The data packets of the chain type are processed by a first distribution procedure. The data packets of the non-chain type are processed by a second distribution procedure. The distribution procedures distribute the data packets to the corresponding request queues according to the protocol property. The corresponding intrusion detection procedure is performed on the data packets in each request queue.
