Abstract: A dial, and timepiece including the dial, including a mother-of-pearl wafer partially covering a support member, and a decorative element arranged on a reverse of the wafer, the decorative element being visible on an obverse of the wafer when subjected to a stimulus and invisible on the obverse of the wafer in the absence of the stimulus. The decorative element has a first empty area on a reverse of the wafer, and a second empty area on the obverse of the wafer, facing the first empty area. A colour compensation layer is deposited on the first empty area or the second empty area, the colour being selected such that the difference in colour ?E in the CIE Lab colour space between the colour compensation layer and the decorative element in the absence of said stimulus, perceived by a user observing the obverse of the wafer, is less than 3.

Abstract: Video coding tools can be controlled by including syntax in a video bitstream that makes better use of video decoding resources. An encoder inserts syntax into a video bitstream to enable a decoder to parse the bitstream and easily control which tools combinations are enabled, which combinations are not permitted, and which tools are activated for various components in a multiple component bitstream, leading to potential parallelization of bitstream decoding.

Abstract: A method of tracking a user's toothcare activity comprises receiving video images of a user's face during, e.g. a toothbrushing session, and identifying, in each of a plurality of frames of the video images, predetermined features of the user's face. The features include at least two invariant landmarks associated with the user's face and one or more landmarks selected from at least mouth feature positions and eye feature positions. Predetermined marker features of a toothcare appliance, e.g. a brush in use are identified in each of the plurality of frames of the video images. From the at least two invariant landmarks associated with the user's nose, a measure of inter-landmark distance is determined. An appliance length normalised by the inter-landmark distance is determined. From the one or more landmarks selected from at least mouth feature positions and eye feature positions, one or more appliance-to-facial feature distances each normalised by the inter-landmark distance is determined.

The method also includes acquiring an offset level of an item of equipment of the vehicle relative to a reference direction, and at least one feature of the counter is determined as a function of the offset level.

Abstract: Described is a task for an automobile interior having at least one subject that creates a video input, an audio input, and a context descriptor input. The video input relates to the at least one subject and is processed by a face detection module and a facial point registration module to produce a first output. The first output is further processed by at least one of: a facial point tracking module, a head orientation tracking module, a body tracking module, a social gaze tracking module, and an action unit intensity tracking module. The audio input relating to the at least one subject is processed by a valence and arousal affect states tracking module to produce a second output and to produce a valence and arousal scores output. A temporal behavior primitives buffer produce a temporal behavior output. Based on the foregoing, a mental state prediction module predicts the mental state of at least one subject in the automobile interior.

Abstract: A PIN diode has an anode spaced away from a central region of a top surface of a substrate, such that the anode is in a corner or at a side edge of the top surface. Alternatively, the PIN diode has an anode surrounded by a shield layer. The PIN diode reduces unwanted parasitic capacitance to increase the reverse isolation of RF switches and to reduce the diffusion capacitance to increase the f3dB frequency specification of amplifier circuits. The PIN diode dramatically reduces the values of both parasitic and diffusion capacitances, which enables its application in switches and amplifiers under a wide variety of bias conditions including reverse, low-moderate forward, and large forward-bias; which enables bonding to a much larger metal area than the active electrode, with negligible increase in the parasitic capacitance; and which enables reliable wire-bonding by presenting a highly planar metal surface.
