Abstract: A system for detecting a presence in an environment to be monitored includes an electrostatic charge variation sensor, a vibration sensor, and an environmental pressure sensor. A processing unit is configured to acquire, from the electrostatic charge variation sensor, an electrostatic charge variation signal, and detect in the electrostatic charge variation signal, first signal characteristics indicative of the presence of a subject in the environment to be monitored. The processing unit further validates the detection of presence of the subject using the vibration and pressure signals provided by the other sensors.

Abstract: An integrated circuit includes sensing circuitry and processing circuitry. The processing circuitry processes received sensor-session requests and received sensor-service requests. Processing a received sensor-service request includes determining a type of the received sensor-service request. In response to determining the received sensor-service request is of a first type, results information is generated in response to the received sensor-service request of the first type based on sensor data generated by the sensing circuitry. In response to determining the received sensor-service request is of a second type, remote-server processing based on the received sensor-service request of the second type is initiated, and a response to the received sensor-service request of the second type is generated based on a received response to the initiated remote-server processing.

Abstract: The present disclosure is directed to a gas sensor device that detects gases with large molecules (e.g., a gas with a molecular weight between 150 g/mol and 450 g/mol), such as siloxanes. The gas sensor device includes a thin film gas sensor and a bulk film gas sensor. The thin film gas sensor and the bulk film gas sensor each include a semiconductor metal oxide (SMO) film, a heater, and a temperature sensor. The SMO film of the thin film gas sensor is an thin film (e.g., between 90 nanometers and 110 nanometers thick), and the SMO film of the bulk film gas sensor is an thick film (e.g., between 5 micrometers and 20 micrometers thick). The gas sensor device detects gases with large molecules based on a variation between resistances of the SMO thin film and the SMO thick film.

Abstract: A device including a sensor is disclosed. In one embodiment, the sensor includes a thermal infrared sensor or a sensor based on CMOS-SOI-MEMS technology (also referred to as “TMOS”). The sensor is capable of performing at least two functions at the same time. The first is remote temperature measurement and the second is presence detection. The sensor passively collects infrared information and a microprocessor coupled to the sensor determines the temperature as well as presence.

Abstract: A system for detection of a touch gesture of a user on a detection surface includes a processing unit, an electrostatic-charge-variation sensor, which generates a charge-variation signal; and an accelerometer, which generates an acceleration signal. The processing unit is configured to: detect, in the charge-variation signal, a first feature identifying the touch; detect, in the acceleration signal, a second feature identifying the touch; detect a temporal correspondence between the first and second features identifying the touch gesture; and validate the touch gesture only in the case where both the first and second features have been detected and the temporal correspondence satisfies a pre-set relation.

Abstract: A system for diagnosing the operating state of a MEMS sensor includes a stimulation circuit, external to the MEMS sensor, configured to generate a stimulation signal designed to be detected by the MEMS sensor. The system has control circuitry, operatively coupled to the stimulation circuit and to the MEMS sensor, so as to control the stimulation circuit to generate the stimulation signal and receive a diagnostic signal generated by the MEMS sensor in response to the stimulation signal. The control circuitry determines an operating state of the MEMS sensor based on the diagnostic signal and an expected response to the stimulation signal by the MEMS sensor.

Abstract: A method for testing the hermetic seal of a packaged device, which includes: a package that delimits a device chamber; and a transducer device, which is arranged within the device chamber and generates an electrical signal indicating at least one physical quantity external to the package. The testing method includes the steps of: imposing a reference pressure in the device chamber; arranging the packaged device in a testing chamber in which a testing pressure is present, different from the reference pressure; and subsequently detecting possible pressure variations within the device chamber.

Abstract: A system for measuring cardiac parameters uses a movements sensor to generate a seismocardiographic signal and a cardiac parameters calculation unit. The cardiac parameters calculation unit provides for generating an envelope signal correlated to the seismocardiographic signal; identifies, in the envelope signal, signal segments having a repetitive pattern; identifies, among the signal segments, pairs of successive peaks such that a first peak of each pair of successive peaks is a systolic peak and a second peak of each pair of successive peaks is a diastolic peak; and calculates a systolic period and a diastolic period for each pair of successive peaks.
