Abstract: A determination is made as to whether touch pressure data acquired from each of a plurality of touch pressure sensors is indicative of abnormal operation. If abnormal operation is indicated, the touch pressure data from each of the plurality of touch pressure sensors, except those touch pressure sensors having touch pressure data indicative of abnormal operation, is summed. Then, the sum is multiplied by a correction factor to produce a touch pressure output indicative of physical force applied to the plurality of touch pressure sensors.

Abstract: An electronic integrated circuit (IC) component is mounted to a substrate. A cap member is applied onto the substrate and covers the electronic IC component. The cap member includes an outer wall defining an opening and an inner wall surrounding the electronic IC component. The inner wall extends from a proximal end at the substrate towards a distal end facing the opening in the outer wall to provide a reception chamber for the electronic IC component and a peripheral chamber between the inner wall and the outer wall of the cap member. An encapsulant material is provided in the reception chamber to seal the electronic IC component without being present in the peripheral chamber.

Abstract: A first electronic component, such as a sensor having opposed first and second surfaces and a first thickness, is arranged on a support member with the second surface facing towards the support member. A second electronic component, such as an integrated circuit mounted on a substrate and having a second thickness less than the first thickness, is arranged on the support member with a substrate surface opposed the second electronic component facing towards the support member. A package molding material is molded onto the support member to encapsulate the second electronic component while leaving exposed the first surface of the first electronic component. The support member is then removed to expose the second surface of the first electronic component and the substrate surface of the substrate.

Abstract: A feedback stage for an integrator circuit is provided. The integrator receives a first input current and a second input current that include respective measurement current components and an offset current component. The integrator integrates the first input current and the second input current and generates a first output voltage and a second output voltage. The feedback stage including a transconductance amplifier detects a difference between the first output voltage and the second output voltage and sinks or sources a first output current and a second output current based on the difference between the first output voltage and the second output voltage. The first output current is additively combined with the first input current and the second output current is additively combined with the second input current to mitigate the offset current component at an input of the integrator.

Abstract: An amplifier stage of an LDO regulator circuit includes an amplifier stage that generates a drive signal in response to a first voltage difference an output voltage of the LDO regulator circuit and a reference voltage. A drive stage having a quiescent current consumption is configured to generate a control signal in response to the drive signal. The control signal is applied to the control terminal of a power transistor. A dropout detector senses whether the LDO regulator circuit is operating in closed loop regulation mode or in open loop dropout mode by sensing a second difference in voltage between the drive signal and the control signal. A quiescent current limiter circuit responds to the sensed second difference by controlling the quiescent current consumption of the drive stage, and in particular limiting current consumption when the LDO regulator circuit is operating in the open loop dropout mode.

Abstract: An electronic device includes an analog to digital converter receiving an analog mirror sense signal from an oscillating mirror and generating a digital mirror sense signal therefrom, and a digital signal processing block. The digital signal processing block cooperates with the analog to digital converter to take a first sample of the digital mirror sense signal at a first time where a derivative of capacitance of the digital mirror sense signal crosses zero, take a second sample of the digital mirror sense signal at a second time between a peak of the digital mirror sense signal and the first time, and take a third sample of the digital mirror sense signal at a third time after the digital mirror sense signal has reached a minimum. Control circuitry determines an opening angle of the oscillating mirror as a function of the first, second, and third samples.

Abstract: A microelectromechanical structure includes a body of semiconductor material having a fixed frame internally defining a cavity, a mobile mass elastically suspended in the cavity and movable with a first resonant movement about a first rotation axis and with a second resonant movement about a second rotation axis, orthogonal to the first axis. First and second pairs of supporting elements, extending in cantilever fashion in the cavity, are rigidly coupled to the frame, and are piezoelectrically deformable to cause rotation of the mobile mass about the first and second rotation axes. First and second pairs of elastic-coupling elements are elastically coupled between the mobile mass and the first and the second pairs of supporting elements. The first and second movements of rotation of the mobile mass are decoupled from one another and do not interfere with one another due to the elastic-coupling elements of the first and second pairs.

Abstract: A substrate and a covering structure coupled to the substrate form a chamber. The chamber houses an emitter configured to emit a radiation, a resonant reflector, a detector, and a fixed reflector. First and second windows extend through the covering structure. The emitter, the first reflector and the second reflector are reciprocally arranged such that radiation emitted from the emitter is reflected by the fixed reflector towards the MEMS reflector for further reflection towards the first window to form an output signal. The detector and the second window are reciprocally arranged such that an incoming radiation passing through the second window is received by the detector. The electronic module can be used for a 3D sensing application.

Abstract: A support substrate has first electric contacts in a front face. An electronic component is located above the front face of the support substrate and has second electric contacts facing the first electric contacts of the support substrate. An electric connection structure is interposed between corresponding first and second electric contacts of the support substrate and the electronic component, respectively. Each electric connection structure is formed by: a shim that is made of a first electrically conducting material, and a coating that is made of a second electrically conducting material (different from the first electrically conducting material). The coating surrounds the shim and is in contact with the corresponding first and second electric contacts of the support substrate and the electronic component.

Abstract: An energy-harvesting generator provides energy for storage in a capacitor. A sensing circuit senses a voltage across the capacitor and generates an activation signal as a function of the sensed voltage. The activation signal is switches from a first value to a second value when the sensed voltage reaches an upper threshold and switches from the second value to the first value when the sensed voltage reaches a lower threshold. A signal transmitter powered by stored energy in the capacitor responds to the activation signal being switched to the second value by activating and transmitting a transmission signal. The signal transmitter further responds to the activation signal being switched to the first value by discontinuing transmission of the transmission signal and deactivating. A duration of time elapsing between de-activation and activation of the transmitter is indicative of an amount of energy harvested by the energy-harvesting electric generator.

The magnitude of the feedback current does not vary with the sensed load current if the magnitude of the sensed load current is not between the lower load current threshold and the upper load current threshold.
