Abstract: A method used in a mobile equipment for authenticating or identifying a user based on his face includes acquiring a sequence of biometric face sample corresponding to successive image frames of the user in a Trusted Execution Environment of the mobile equipment, and, in the Trusted Execution Environment, modifying or replacing some of the biometric face samples in the sequence, so as to generate a modified sequence with test biometric face samples. The method includes transmitting the modified sequence to a Rich Execution Environment of the mobile equipment, and classifying at least one portion of the biometric face samples using a classifier in the Rich Execution Environment, so as to generate for each classified biometric face sample a set of intermediary outputs and a classification result.

Abstract: A method for selecting frames used in face processing includes capturing video data featuring a face of an individual and determining with a processing unit at least one image quality indicator for at least some frames in the video data. The quality indicator is used for selecting a subset of the frames and a sequence of frames is determined corresponding to a movement of a body portion detected in the video data and/or corresponding to a response window during which a response to a challenge should be given. At least one second frame is added to the subset within a predefined interval before or after the sequence and the selected frames are stored in a memory.

Abstract: A valve actuating device includes a camshaft, a cam, and a lubricant conducting device. The camshaft has an oil supply duct extending in a longitudinal direction of the camshaft and a discharge orifice extending in a radial direction of the camshaft and in fluid communication with the oil supply duct. The cam is fixedly mounted to the camshaft to rotate with the camshaft, the cam having a contact surface and a lateral wall facing in an axial direction of the camshaft towards the discharge orifice. The lubricant conducting device is arranged to direct oil over the lateral wall of the cam towards the contact surface.

Abstract: A pose rectification method for rectifying a pose in data representing face images, comprising the steps of: A—acquiring a least one test frame including 2D near infrared image data, 2D visible light image data, and a depth map; C—estimating the pose of a face in said test frame by aligning said depth map with a 3D model of a head of known orientation; D—mapping at least one of said 2D image on the depth map, so as to generate textured image data; E—projecting the textured image data in 2D so as to generate data representing a pose-rectified 2D projected image.

Abstract: In a grinding machine for beveling or grooving an ophthalmic lens in guided or non-guided modes, the support shaft for the grinding tool is mounted to be movable relative to that carrying the ophthalmic lens to be processed. Associated with it are displacement means adapted to procure its guided displacement parallel to its axis. Between this mobile support shaft and the associated displacement means are selectively engageable coupling means. These procure either axial displacement of the mobile support shaft by virtue of the drive action of said displacement means or disengagement relative to said displacement means at least.

Abstract: A machine for grinding ophthalmic lenses comprises a frame and a support to which an ophthalmic lens to be processed may be attached pivoted to the frame about an axis parallel to the axis of the grinding tool. A counterweight on the support is movable relative to the frame in a direction orthogonal to the pivot axis. A drive device controls movement of the counterweight. A guide cam is disposed on the path of movement of the counterweight. The machine may be used for trimming and/or bevelling or grooving an ophthalmic lens.

Abstract: The process for the production of a cyanopyridine by the conversion of a monoalkylpyridine, the alkyl having one to four carbon atoms, with (a) oxygen or air and (b) ammonia in the gaseous phase in the presence of one of several specific catalysts is known.

Preferably the catalyst has a grain size of 100 to 250.mu.. The molar ratio of the air to the monoalkylpyridine can be from 80:1 to 300:1, and preferably is from 150:1 to 260:1. The molar ratio of the ammonia to the monoalkylpyridine can be from 3.5:1 to 12:1, and preferably is from 4:1 to 9:1.
