A sensor device for an electronic apparatus is provided with: a sensing structure generating a first detection signal; and a dedicated integrated circuit, connected to the sensing structure, detecting, as a function of the first detection signal, a first event associated to the electronic apparatus and generating a first interrupt signal upon detection of the first event. The dedicated integrated circuit detects the first event as a function of a temporal evolution of the first detection signal, and in particular as a function of values assumed by the first detection signal within one or more successive time windows, and of a relation between these values.

Sensor device provided with a circuit for detection of single or multiple events for generating corresponding interrupt signals

An inertial device that is integratable in a portable electronic device includes: an inertial sensor for generating at least one raw acceleration signal in response to accelerations caused by movements of walking and running of a user of the pedometer; and a processing unit, associated to the inertial sensor for counting a number of steps of the user of the pedometer on the basis of the raw acceleration signal. The inertial sensor and the processing unit are both encapsulated within a single package for integrated circuits, which can be coupled to a circuit board of an electronic device and is provided with at least one connection terminal for making the number of steps available to the outside world.

A pico-projector device includes a light source operable to generate a light beam as a function of an image to be generated, a mirror mechanism operable to direct the light beam towards a displaying surface, and a driving circuit that supplies driving signals for controlling movement of the mirror mechanism. The driving circuit includes a compensation stage that receives angular velocity signals from a gyroscopic sensor coupled to the pico-projector device and generates the driving signals as a function of the angular velocity signals, thereby stabilizing the image projected on the displaying surface with respect to undesired movements of the pico-projector device.

A sensor device for an electronic apparatus, including a sensing structure for generating a first detection signal, and a dedicated integrated circuit connected to the sensing structure for detecting a first event associated with the electronic apparatus and for generating a first interrupt signal upon detection of the first event. The dedicated integrated circuit detects the first event as a function of changes to the first detection signal over time (i.e., temporal evolution), and in particular as a function of values assumed by the first detection signal within one or more successive time windows, and of a relation between these values.

A manual pointing device for a computer system, the device having at least one key that can be actuated manually by a user, a click-event detection module coupled to the key to detect actuation thereof on first, second, and third detection axes via an inertial sensing circuit elastically coupled to a casing with a board, the inertial-sensor circuit structured to be carried on the board so as to oscillate and to rotate about the second detection axis.

A user controlled device, movable into a plurality of positions of a three-dimensional space, includes a MEMS acceleration sensor to detect 3D movements of the user controlled device. The device, such as a mouse, sends control signals correlated to the detected positions to an electrical appliance, such as a computer system. A microcontroller processes the output signals of the MEMS acceleration sensor to generate the control signals, such as screen pointer position signals and 'clicking' functions.

Detection of an anomalous event in an electronic apparatus includes detecting accelerations acting on the electronic apparatus, establishing a normal-mode range of accelerations that corresponds to normal operation of the apparatus, and detecting the anomalous event when a level of acceleration of the electronic apparatus exits the normal-mode range and remains outside the normal mode range for more than a defined duration. The method includes displacing the normal-mode range toward a current level of acceleration of the electronic apparatus while the level of acceleration remains outside the normal-mode range. Additionally, the normal-mode range is increased toward a maximum size while the level of acceleration remains outside the normal-mode range, and is decreased toward a minimum size while the level of acceleration is within the normal-mode range.
