Title: Optimally Segmenting an Image
Inventor: LASSERRE SEBASTIEN
IPC: H04N7/26
Filed: 2012-04-13
Abstract: Segmenting a frame of pixels into a plurality of blocks each having a block type comprises performing an initial segmentation (S100) of the frame into a set of initial blocks, and determining a block type associated with each initial block. For each block type, an associated set of quantizers is determined (S104) based on data corresponding to pixels of blocks having the block type. The segmentation is selected (S106), from among a plurality of possible segmentations defining an association between each block of this segmentation and an associated block type, which minimizes an encoding cost. The cost is estimated based on a measure of the rate necessary for encoding each block using the set of quantizers associated with the block type of the encoded block according to the concerned segmentation. The encoding cost may be a Lagrangian cost. The segmentation can therefore be modified to optimize the encoding cost. A frame of pixels may be encoded, e.g. using scalable encoding, in which segmentation of the frame as described above is used.

Title: Uplink antenna selection in a user equipment on the basis of detected fading conditions for downlink signals
Inventor: ROUSU SEPPO
IPC: H04B7/04
Filed: 2012-06-29
Abstract: At the user equipment (UE), at leastÂ  two radio wave signals are received, preferably on different respective UE antennas. Fading conditions in relation to the received signals are detected and uplink antenna selection in the user equipment is controlled at least on the basis of the detected fading conditions. Detecting the fading conditions may involve determining the signal delay spread between received radio wave signals, determining which antenna receives a signal first, detecting line-of-sight, or detecting a scattering scenario. Detecting the fading conditions may involve determining a fading parameter such as fading delay, Doppler spread, angle of arrival or polarization. In an alternative embodiment transmit antenna selection at the UE is based on one or more motionrelated characteristics of the UE. In either embodiment, a network entity such as a base station may perform the antenna selection on the basis of its analysis of an uplink signal from the UE, combined with fading conditions or motion-related characteristics communicated from the UE. The antenna selection may additionally take into account a signal quality parameter such as RSSI, BER, SNR or SIR.

Title: Multi-factor user authentication via a mobile device, using a separate token carrying encryption keys
Inventor: YAU ARNOLD
IPC: G06F21/35
Filed: 2013-03-01
Abstract: A method and system of authenticating a computer resource such as an application or data on a mobile device uses a contactless token to provide multi-factor user authentication. User credentials are stored on the token in the form of private keys, and encrypted data andpasswords are stored either on the device or in cloud storage. When a user requests access to the resource 1, an encrypted password is transmitted to the token 5 and decrypted using a stored private key 6. An unencrypted data key or password is then transmitted back to the device 7, encrypted under a session key generated as a result of strong mutual authentication between the device and the token. Authentication is validated through the return transmission and separate authentication from the user on the device. This allows for secure validation and minimises unauthorized data access. Validation of the user authentication may be carried out on the token prior to decrypting the password.
Patent GB-2513850-A (GB)
Title: Access control system
Inventor: ROSEBERH ODD HELGE
IPC: H04L29/06
Filed: 2013-05-03
Abstract: An access control system is configured for data communication with at least a first remote service provider (eg power company, hospital with remote patient monitoring, security services company) via a wide area telecommunications network and for data communication with at least a first local device associated with the service provider (eg electricity meter, health monitoring device, home security system) via local data communication. The access control system is configurable to facilitate data communication between the first remote service provider and the first local device. The access control system comprises a gateway device and virtual machines VM1-VMN associated with at least one local device and at least one service provider. When a service provider requests connection with a local device, it supplies an identifier. The gateway rejects the connection request. However, the VM associated with the local device compares the identifier with a list of authorized identifiers and associated predefined addresses; and if it finds a match, it sets up a connection to the predefined address, thereby effectively calling back the service provider such that it may communicate with the local device.

Title: Electrosurgical apparatus
Inventor: AMOAH FRANCIS
IPC: A61B18/18
Filed: 2013-05-08
Abstract: Disclosed is electrosurgical apparatus comprising an RF signal generator, a delivery probe, a signal detector and a controller, whereby the controller uses the detected signal to monitor energy accumulated in the tissue and control the profile of each of the pulses to keep the average power supplied to the tissue below a target value. The pulse may be a composite pulse with an ON and OFF portions totalling pulse duration T, and a limit for the average power delivered (i.e. total energy delivered over the duration of the ON and OFF portions divided by the pulse duration) may be selectable by the operator. The ON portion may have multiple sub-portions of different voltages for different purposes, such as initiating and sustaining cutting. Each pulse may therefore be automatically controlled for pulse width and/or power supplied, so that the RF signal effectively responds intelligently to conditions at the probe tip during treatment.

Title: Remote port mirroring using IGMP publish/join functions to establish mirrored data streams
Inventor: KEESARA SRIKANTH
IPC: H04L45/16
Filed: 2013-06-20
Abstract: The claims specify a system wherein a switch 110 establishes a mirrored data stream 160 based upon a message 162 specifying the destination 124 for the mirrored stream. Preferably the switch maps a port 3 to an identifier MIR1 stolen from another protocols identifier space and the mirroring request includes this identifier. In the embodiments the other protocol is IGMP (Internet Group Management Protocol). A mapping from a port 3 to an address in the IGMP multicast group table is established 155,157 and the address is publicised. The mirror destination 124/126, which may include an analyser, requests mirroring with an IGMP join message 162 include the address MIR1. The switch 110 then mirrors the data from port 3 to repository 124 using IGMP publish messages 160, as well as sending the data to the original destination 122. The traffic on port 3 does not need to use a multicast address. The invention does not need to establish a VLAN or similar path configuration to route data to the repository 124.
