    • Systems and methods for reading a RFID-tag signal in the presence of noise and other propagation and circuit impairments using a RFID-tag reader are disclosed. The method includes receiving with a RFID-tag reader multiple copies of an original RFID-tag signal from a RFID tag. The original RFID-tag signal comprises an original bit sequence representative of information stored in the RFID tag. At least some of the received RFID-tag signal copies differ from one another due to noise or other signal impairments. The received multiple copies are processed on a sample-by-sample basis in the RFID-tag reader using digital signal processing techniques to obtain an improved received digitized RFID tag signal that substantially removes the noise and other impairments. This improved signal is used to recover the original bit sequence and thus the information stored in the RFID tag.
    • 公开了使用RFID标签读取器在存在噪声和其他传播和电路损伤的情况下读取RFID标签信号的系统和方法。 该方法包括使用RFID标签读取器从RFID标签接收原始RFID标签信号的多个副本。 原始RFID标签信号包括表示存储在RFID标签中的信息的原始比特序列。 由于噪声或其他信号障碍,至少一些所接收的RFID标签信号拷贝彼此不同。 在RFID标签读取器中,使用数字信号处理技术逐个采样处理所接收的多个拷贝,以获得基本上消除噪声和其他损伤的改进的接收数字化RFID标签信号。 该改进的信号用于恢复原始比特序列,从而恢复存储在RFID标签中的信息。

    • The present invention provides a method and system in a telecommunications network for restoring network element failures or network link failures in case not all network elements possess distributed restoration capabilities, for example during an introduction-phase of the distributed restoration system, or in case a network consists of different kinds of network elements provided by different providers, i.e. a multivendor network. The distributed restoration of network elements which do not possess these capabilities is taken over by the distributed restoration module of network management. The interface which is used for communication between a network element and the network management, is preferably implemented according to the q3 standard. The distributed restoration module within the network management can be replaced by a central restoration module which has the advantage over the distributed module that a better solution will be found.

    • A resequencing system (DDM, TSG, IC, REG, SUB, RSU) is disclosed for resequencing the cells of a cell stream transmitted through the cascaded connection of a first switching node (SN'), a buffer register (OB) and a second switching node (SN). It includes: a resequencing means (TSG, IC, REG, SUB, RSU) associated to the second switching node (SN), a delay measurement circuit (DDM) associated with the buffer register (OB) and adapted to measure the time delay to which each of said cells is submitted in said buffer register (OB), means to communicate the delay thus measured for each cell to the resequencing means (TSG, IC, REG, SUB, RSU). After said cell has been switched by said second switching node (SN), the resequencing means (TSG, IC, REG, SUB, RSU) submits this cell to a time delay equal to the difference between a predetermined constant time delay value and the communicated delay.

    • A method is described for rerouting a data stream previously routed via a route through a switching network which has now failed. The method includes the steps of detecting the failure on a link (L19) between first (SN1) and second (SN9) switching nodes in one of these switching nodes (SN1); transmitting from this one switching node (SN1) a request message (REQ) with first (IDA) and second (IDB) address fields containing addresses of the first (1) and second (9) switching nodes, respectively; in each switching node having received the request message (REQ) retransmitting it, until an alternative route for the data stream is found between two end switching nodes of said alternative route; and by one of these end switching nodes (SN1) chosen according to a predetermined rule after the alternative route has been found, allocating the data stream to this alternative route and transmitting it thereon.
