Title: Methods and apparatus for biometric authentication in an electronic device
Inventor: MICHAEL PAGE
IPC: G10L17/00
Filed: 2016-12-20
Abstract: Biometric authentication comprises receiving a voice data signal 200 and performing a biometric authentication algorithm which comprises comparing signal features with stored templates 204 corresponding to an authorised users voice. A control signal comprising an indication of threshold values, e.g. a false acceptance rate FAR or a false rejection rate FRR, is received 210. Comparison of a generated biometric authentication score with threshold values 216 is used to determine whether the speaker is an authorised user. Threshold values may be based on a security level required for a spoken command. A method used in an electronic device comprises acquiring a voice data signal (300, figure 4) and initiating a speech recognition algorithm (302, figure 4) to determine content (304, figure 4). A security level associated with the content is determined (310, figure 4) and an indication of thresholds which depend on the security level associated with the content are provided to a biometric authentication system (314, figure 4) for use in determining whether the user is an authorised user. Threshold values may be based on data acquisition context e.g. location, velocity or acceleration of the device. Speech recognition may be used to determine semantic content.

Title: Computing systems and methods for processing graphics data using cost indications for sets of tiles of a rendering space
Inventor: JOHN WILLIAM HOWSON
IPC: H04N19/10
Filed: 2017-01-12
Abstract: A computing system comprises graphics rendering logic and image processing logic. The graphics rendering logic processes graphics data to render an image using a rendering space which is sub-divided into a plurality of tiles. Cost indication logic obtains a cost indication for each of a plurality of sets of one or more tiles of the rendering space, wherein the cost indication for a set of one or more tiles is suggestive of a cost of processing rendered image values for a region of the rendered image corresponding to the set of one or more tiles. The image processing logic processes rendered image values for regions of the rendered image in dependence on the cost indications for the corresponding sets of one or more tiles. The image processing logic may involve image coding including quantisation and the cost indication may determine either the order in which image regions are processed or the level of quality at which the image regions are processed or be used to allocate budgets of data for encoded regions.

Title: Closure for a container lid
Inventor: GARY M BAUGHMAN
IPC: B65D81/20
Filed: 2015-08-03
Abstract: A single-piece, molded plastic closure is disclosed and is constructed and arranged for assembly into a container lid opening. The closure includes an annular side wall having a lid engaging portion and an end panel. The end panel is configured with an annular recessed section and an annular frustoconical section which surrounds the annular recessed section.

IPC: F04C5/00
Filed: 2016-03-17
Abstract: A pump comprising a housing and a rotor rotatably accommodated in the housing and having a longitudinal axis of rotation in use. The housing comprises a resilient seal member, an inlet and an outlet for fluid. The rotor comprises first and second surface areas, and the rotor and housing are cooperatively configured such that the second surface area is radially recessed from the first surface area, forming a chamber with an interior surface of the housing, and the first surface area seals against the interior surface, operative to contain the fluid within the chamber as the rotor rotates in use.

Title: Automatically adjusting headgear for patient interface
Inventor: MARK ARVIND MCLAREN
IPC: A61M16/06
Filed: 2014-04-24
Abstract: A patient interface (fig. 44) comprises a mask and headgear, the headgear comprising an elastic strap, a non-elastic core 1316 and a restriction mechanism 1300 connected to both the elastic strap and non-elastic core. The restriction mechanism requires different resistance forces to elongate and retract the headgear, and comprises a directional lock including a housing 1304 having a cavity 1306, and a lock member 1308 within the cavity. The non-elastic core passes through an orifice in the housing and an orifice in the lock member.

When the lock member is aligned with the free movement surface (fig. 21A), the non-elastic core may have a straight path through the directional lock and may be free to move in direction 1318. However, when the non-elastic core is moved in the opposite direction 1320, the lock member may rest against the locking surface to create an angled high-friction path for the non-elastic core (fig. 21B). The directional lock may comprise two lock stages having different locking behaviours.

Title: System and methodology for minimizing perforating gun shock loads
Inventor: CARLOS ERIC BAUMANN
IPC: E21B43/119
Filed: 2016-11-18
Abstract: A technique facilitates perforating along specific regions of a wellbore without creating detrimental transient pressure changes along a perforating gun string. In non-perforation regions, pressure charges may be used to maintain pressure within the gun string without creating perforations through the surrounding casing and into the surrounding formation. Each pressure charge may comprise a casing with an explosive material disposed in the casing. However, the components and structure of the pressure charge enable detonation and the corresponding increase in pressure within the gun string without creating perforations.
