Abstract: Local descriptors are extracted from digital image information and digital depth information related to digital images. The local descriptors convey appearance description information and shape description information related to the digital images. Global representations of the one or more digital images are generated based on the extracted local descriptors, and are hashed. Visual search queries are generated based on the hashed global representations. The visual search queries include fused appearance description information and shape description information conveyed in the local descriptors. The fusing may occur before the global representations are generated, before the hashing or after the hashing.

Abstract: A sensor of volatile substances includes: a first electrode structure and a second electrode structure capacitively coupled, comb-fingered, and arranged coplanar in a plane; and a sensitive layer, of a sensitive material that is permeable to a volatile substance and has electrical permittivity depending upon a concentration of the volatile substance absorbed by the sensitive material. The sensitive layer extends from opposite sides of the plane.

Abstract: A micromechanical device includes a fixed structure, a mobile portion rotatable about a first rotation axis, and a first actuation structure arranged between the fixed structure and the mobile portion to enable rotation of the mobile portion about the first rotation axis. The mobile portion includes a supporting structure, a tiltable platform rotatable about a second rotation axis, transverse to the first rotation axis, and a second actuation structure coupled between the tiltable platform and the supporting structure. Stiffening elements are arranged between the supporting structure and the fixed structure. The micromechanical device may be used within a picoprojector.

Abstract: One or more embodiments are directed to zero-rate level compensation systems. One such system includes stationary detection circuitry that receives gyroscope signals output by a gyroscope and determines whether the gyroscope is stationary based on the gyroscope signals. The stationary detection circuitry generates a stationary gyroscope signal indicating the gyroscope is stationary based on a determination that the gyroscope is stationary. A temperature sensor senses temperature and outputs temperature signals. Zero-rate level estimation circuitry receives the stationary gyroscope signal and a temperature signal associated with the stationary gyroscope signal, and iteratively estimates one or more zero-rate level compensation parameters based on the stationary gyroscope signal and the temperature signal.

Abstract: A MOSFET device comprising: a structural region, made of a semiconductor material having a first type of conductivity, which extends between a first side and a second side opposite to the first side along an axis; a body region, having a second type of conductivity opposite to the first type, which extends in the structural region starting from the first side; a source region, having the first type of conductivity, which extends in the body region starting from the first side; a gate region, which extends in the structural region starting from the first side, traversing entirely the body region; and a shielding region, having the second type of conductivity, which extends in the structural region between the gate region and the second side. The shielding region is an implanted region self-aligned, in top view, to the gate region.

Abstract: A circuit includes an input node configured to receive an input reference signal. An output node is configured to provide a replica of the input reference signal with a respective scaling ratio to the input reference signal at the input node. A digital-to-analog converter has a reference input configured to receive the input reference signal from the input node, a digital input configured to receive a digital input signal having a digital signal value, and a digital-to-analog converter output configured to provide an output signal from the digital-to-analog converter resulting from conversion to analog of the digital input signal. The output node of the circuit is configured to sense the output signal from the digital-to-analog converter and to provide the replica of the input reference signal at the output node.
