Title: Establishing real time multimedia session amongst multiple devices with election of relaying control and media service devices
Inventor: ZHOU XIANG
IPC: H04L29/06
Filed: 2012-10-11
Abstract: Existing systems (eg. the Internet Protocol Multimedia Subsystem (IMS)) establish and provide services/sessions using central servers. The invention discloses a system wherein devices wishing to participate in a session calculate capability scores based on their hardware capabilities and network quality of service characteristics and submit them to a moderator (which may be one of the participating devices). Based on the capability scores an application service device and a media service device are selected. The application service device establishes SIP connections to all other participating devices to receive and forward control information. The media service device establishes RTP/RTCP connections to receive and forward real-time multimedia streams. Preferably the device with the highest score is selected as the media service device and that with the second highest score as the application service device. If none of the devices is capable of fulfilling application/media service duties, the system can select central application/media servers to the role.

Title: Authentication of an online user using controllable illumination
Inventor: BUD ANDREW
IPC: G06V10/145
Filed: 2013-02-21
Abstract: Methods, systems, and computer program products for authenticating an online user. Authentication involves sending a code from a server to a user-device equipped with a source of illumination and a camera capable of capturing video imagery of the online user. The user device receives the code, modulates the source of illumination in accordance with the code, and captures video imagery of the user while the source of illumination is being modulated according to the code. The captured video imagery of the online user is sent to the server where it is analyzed to detect evidence of changes in illumination that correspond to the code. If good correspondence is found, the user may be authenticated. Similar methods may be applied to other biometric data. Applications of the authentication include identify validation, pseudonym verification, and distinguishing human from non-human access attempts. The illuminations could take the form of coloured blocks on a display screen of the user-device.

Title: Amplitude limiter for receiver circuitry in an RFID tag reader
Inventor: MCFARTHING TONY
IPC: H03G3/30
Filed: 2013-10-28
Abstract: A tag reader (10, fig.1) in a near-field communication (NFC) system must demodulate a signal, for example a load-modulated signal, in which the modulation created by a passive device such as an RFID tag (50, fig.1) may be small in comparison with the high-level signal produced by the tag reader. The invention provides for demodulation by first applying upper and lower clip levels 14a,b to a signal received in the reader antenna 12. The clipping circuit 14 is arranged to provide a clipped signal (solid line, fig.3) corresponding to a combination of a first portion of the signal below the lower clip level and a second portion of the signal above the upper clip level. After clipping, the modulated part of the signal corresponds to a greater portion of the overall signal, and thus the requirements placed on an analogue-to-digital converter for the clipped signal are reduced. Prior to reception of a load-modulated signal, the clip levels may be set in a feed-forward manner based on preset values or on a detected change in the overall signal; the clip levels may subsequently be set by feedback.

Title: Full wave reverse time migration
Inventor: AMUNDSEN LASSE
IPC: G01V1/30
Filed: 2014-01-14
Abstract: Marine seismic data is recorded by receivers 8 on a recording surface 7 below an ocean surface 6. The seismic data comprises at least two data quantities of a seismic wavefield (e.g. pressure and a component of the particle velocity field). The recorded data quantities are injected on a first velocity model using a forward propagator to generate a forward propagating down-going wavefield. The recorded data quantities are then injected on a second velocity model using a backward propagator so that an up-going wavefield is back propagated from said recording surface, thus producing a backward propagating up-going wavefield. The backward propagating up-going wavefield is compared with the forward propagating down-going wavefield to produce an image of at least one scatterer or reflecting boundary in the earth's interior.

Title: Tessellation method for assigning a tessellation factor per point and device performing the method
Inventor: KIM SEOK HOON
IPC: G06T17/20
Filed: 2014-07-08
Abstract: Disclosed is a tessellation method for use in a graphics pipeline that includes a hull shader and a tessellator. First a tessellation factor is assigned, S110, to each of a plurality of points in a patch (e.g. quad-patch, tri-patch or Isoline) input into a hull shader. The tessellation factor may be computed within the hull shader, or pre-computed and input to the hull shader along with the input points. New points are generated in the vicinity the input points (for example on the same face or the same edge as the input point) based on the tessellation factor assigned to the input point, S120. Topology information that includes the connective relationship between the input points and the new points may be generated in order to create primitives when a crack between faces occurs, S130. In one embodiment the coordinates of the new points along with topology information are output to a domain shader, S140. The invention aims to minimise the appearance of cracks between adjacent faces that can occur when adjacent faces and edges have different tessellation factors.

Title: Digital accessory interface calibration
Inventor: WILLEM ZWART
IPC: H04L7/00
Filed: 2015-05-11
Abstract: An audio system comprises a master device, a slave device accessory and a wired connection including at least a first wire for transmitting master clock data signals to the slave and a second wire for transferring data between the devices in half-duplex fashion. In order to compensate for a round-trip transmission delay, the slave transmits a synchronisation data pattern on the second wire, wherein the synchronisation data pattern comprises signal level transitions at timings that are based on the received master clock signal and an initial delay value stored in the slave (tds, fig. 22). The master determines whether the timings of the received signal level transitions are early or late, and transmits timing delay control data on the second wire based on the determination. The slave updates the stored delay value and the process is repeated to converge on a delay value such that the total round trip delay equals one bit period.
