Abstract: In a context of transient disturbance occurring ata networking equipment receiving and forwarding data packets on a plurality of links according to a scheduling policy, a salient idea is to detect retransmitted packets among the received packets, the retransmitted packets being received by the networking equipment, corresponding to retransmissions of packets previously received and forwarded by the networking equipment on one of the links. The retransmissions of the packet, previously forwarded on one of the links, are representative of a disturbance of the link and the scheduling policy is advantageously adjusted to balance at least a part of the data traffic from that link to the other links.

Abstract: A radio frequency identification (RFID) reader is contained in a mobile station. The RFID reader includes a transmitter for transmitting an interrogating radio frequency (RF) signal. It includes a receiver for receiving responding RF signals generated in corresponding pairs of RFID tags. Each responding RF signal contains information identifying a corresponding access point (AP). The RFID tag pairs are attached to corresponding regions of each location of corresponding locations. A processor of the RFID reader selects a responding RF signal based on signal strength and derives the information contained in the selected responding RF signal that identifies a corresponding AP among several access points that is the most appropriate one to associate with in a handoff operation.

Abstract: A network element adapted to be connected to a communication network includes a set of devices, the devices being configured to receive one set of available services. The network element is a bandwidth manager that is configured to obtain, for couples defined by a service of the set of services and a device of the set of devices, a bandwidth for each flow between the service and the device of the couples; obtain a priority for the flows to be delivered between the services and the devices of the couples; solve a 0-1 Knapsack problem by applying the obtained bandwidths and priorities and by considering an available downlink bandwidth associated with the communication network, to identify one or more allowable flows to be delivered between services of the set of services and devices of the set of devices; and allow the identified one or more allowable flows to be delivered to the corresponding devices of the communication network.

Abstract: A radio frequency identification (RFID) reader identifies in which room among several rooms the RFID reader is more likely to be located. The RFID reader includes a transmitter for transmitting an interrogating radio frequency (RF) signal. It includes a receiver for receiving RF signals generated in corresponding pairs of RFID tags. The RFID tag pairs are attached to corresponding regions of each of the rooms. Each of said RFID tag pair including a first RFID tag and a second RFID tag that are spaced from each other by a distance that is larger or equal to ?/4 and smaller than or equal to ?/2 with respect to a frequency of a responding RF signal originated in the pair of RFID tags. A processor selects a larger RSSI of the RSSI's of the signal pair. The processor determines a corresponding sum of the RSSI's selected from each signal pair associated with each room. The processor evaluates in accordance with determined sums, the location in which said RFID reader is more likely to be located.

Abstract: The proliferation of digital devices has favored an explosion of the amount of image data stored by a user, and it is quite easy for a user to end up with many image duplicates in the user's image library. Prior art solutions can still be optimized with regard to detection of duplicate images in data storage. Notably, user intervention is to be restricted. A correspondence is detected between a first and a second image of the collection, and metadata is associated with the second image that characterizes the detected correspondence. Then, a predetermined image collection management action is applied to second images according to the associated metadata.

Abstract: The present invention relates to a method for uploading in an on-line storage system a file from a user client device through a gateway connected to the client device through a local area network and to the on-line storage system through a wide area network. The on-line storage system comprises a storage server coupled to a target storage device in which the file is to be stored. A gateway receives from the user client device an uploaded file. If the file is not present in the target storage device, the gateway uploads the file to the target storage device, and if the file is present in the target storage device, the gateway creates a link to the file stored in the target storage device.

Abstract: The present invention relates to an image processing apparatus and device intended to temporally modulate a sequence of source images with a modulation image comprising at least one anti-copy pattern. According to the invention, it is proposed that the modulation image be generated on the basis of the source image to be modulated in such a way as to place the patterns at locations of the image that may hinder the person watching an illicit copy of the video sequence (filmed for example by a camcorder). The modulation image is for example an image of the secondary contours of the image. The patterns are therefore placed in the low-gradient zones of the source image.

Abstract: A method for addressing cells in devices via an I2C bus is suggested, in which the common addressing scheme is supplemented by a ‘Data Transfer Mode’ byte. The ‘Data Transfer Mode’ byte specifies the number of the address and data bytes to follow the device addressing and thereby allows for orthogonal and scalable addressing of cells inside a device connected to the bus. The method is fully compatible to the existing I2C standard for writing to the slave device. Setting up and terminating a connection between a master and a slave as well as acknowledging receipt of a byte follows the standard.

Abstract: The invention concerns a complex number multiplier receiving the binary number A, B, C and D complimentarily coded in pairs so as to perform the complex multiplication (A+jB)*(C+jD). A first processing stage enables to perform the operations A?B, C?D, and A+B whereof the results are binary numbers in base two with a redundant binary format, and a borrow-save coding for subtractions and carry-save coding for addition. A second processing stage converts said results into coded binary numbers in base four. A third processing stage enables to perform multiplication (A?B)C, (C?D)B and (A+B)D with a redundant binary format and a borrow-save coding. A last stage comprises two adders for working out the real part (A?B)C+(C?D)B and the imaginary part (A+B)D+(C?D)B in a redundant binary format and a borrow-save coding.
