In an embodiment a sensor system includes a first sensor having a first thermistor configured to sense a change in heat flow and a first heater configured to heat the first thermistor and a second sensor having a second thermistor configured to sense a change in heat flow and a second heater configured to heat the second thermistor, wherein a heat conduction path between the first heater and the first thermistor has a higher thermal conductivity than a heat conduction path between the second heater and the second thermistor.

Sensor system, sensor array and process of using the sensor system

In an embodiment A package includes a casing having an opening and enclosing a cavity, a die accommodated in the cavity and a membrane attached to the casing, the membrane being air-permeable, covering and sealing the opening, wherein the membrane is configured to allow only a lateral gas flow, and wherein a blocking member is configured to block a vertical gas flow through the membrane into the cavity, the blocking member tightly covering a surface of the membrane at least in an area comprising the opening.

Packaged die and assembling method

A sensor component and a mobile communication device including a sensor component are disclosed. In an embodiment a sensor component includes a subcomponent configured to sense a gas level including a resistive heater and a gas sensitive element disposed on the resistive heater; a package enclosing a cavity and accommodating the subcomponent, the package including a first opening in a position facing the gas sensitive element of the subcomponent and a second opening configured to allow a flow of gas to enter the package through the first opening and exit the package through the second opening; and an evaluation circuit configured to generate an output signal indicative of a speed of the flow of gas in response to electrical power to be supplied to the resistive heater.

Sensor component and mobile communication device including the same

A method and apparatus for operating a gas sensor are disclosed. In an embodiment a method for operating a gas sensor includes providing, by at least one gas sensor element, a sensing signal and correcting, by a neural network, the sensing signal, wherein the neural network comprises an input layer, an output layer and at least one hidden layer, wherein the input layer comprises a given number k&#x3e;1 of input neurons for each gas sensor element, and wherein a respective gas sensor element provides its sensing signal to one of the corresponding input neurons dependent on a measurement parameter applied to the at least one gas sensor element.

Method and apparatus for operating a gas sensor

A method for measuring a behavior of a MEMS device is disclosed. In an embodiment a method includes mounting the MEMS device to a testing apparatus that comprises a vibration source, wherein the MEMS device comprises a 6-axis or 9-axis inertial sensor, applying a vibration to the MEMS device by the vibration source and simultaneously moving the testing apparatus according to a predefined movement pattern, reading output data provided by the inertial sensor and comparing the output data to the predefined movement pattern and/or reading output data provided by the inertial sensor and calculating a frequency response curve of the inertial sensor.

Method for measuring a behavior of a MEMS device

A device and a corresponding method are provided for reducing an electromagnetic field in a vehicle. A control unit for a vehicle is designed to determine one or more properties of an electromagnetic interference field. The control unit is further designed to incite an emission unit in the vehicle to emit an opposing field which reduces a strength of the interference field in a first zone around and/or in the vehicle.

Field neutralization during inductive charging

An access control device of a vehicle is configured to detect the spatial position of the access element of the vehicle safety unit relative to the vehicle via electromagnetically detecting the distances and angles between several low-frequency transmitting antennas of the vehicle safety unit and the low-frequency receiver of the access element. The access control device is also configured to detect the location position of an external induction charging unit relative to the vehicle via electromagnetically measuring the distance and angle between at least two transmitting antennas of several low-frequency transmitting antennas and at least one receiving antenna of the induction charging unit.
