Magnetic sensor device and method for a magnetic sensor device having a magneto-resistive structure

The present disclosure relates to a magnetic sensor device having at least one magneto-resistive structure. The magneto-resistive structure comprises a magnetic free layer configured to generate a closed flux magnetization pattern in the free layer, and a magnetic reference layer having non-closed flux reference magnetization pattern; and a magnetic flux concentrator configured to increase a flux density of an external magnetic field in the magnetic free layer.

Magnetic sensor device and magnetic sensing method

A method records and transmits data between a transmission unit that has a first antenna and a measurement module which has a sensor for recording measured variables and converts the measured variables into electric signals. Data is bi-directionally transmitted between the measurement module and the transmission unit located within the near field of the measurement module by use of a second antenna that is arranged on the measurement module. The electromagnetic energy of the signal that is applied to the second antenna is transformed and temporarily stored by a reception unit which is arranged downstream of the second antenna. The first antenna of the transmission unit is put in an inactive state at least during the time the measured variables are sensed by the measurement module or the sensors.

Method for wireless data transmission between a measurement module and a transmission unit

A resonator element for the absorption and/or conversion of electromagnetic waves having a predefined wavelength, in particular infrared radiation having a wavelength of 2 &#x3bc;m to 200 &#x3bc;m, into heat, has a three-layer structure formed of a first metal layer, a second metal layer and a dielectric layer interposed between the two metal layers. The maximum lateral dimension of the layers is in the range between one quarter and a half of the predefined wavelength.

Resonator element and resonator pixel for microbolometer sensor

A method and apparatus for homogeneously magnetizing an exchange-coupled layer system of a digital magnetic memory cell device comprising an AAF layer system and an antiferromagnetic layer that exchange-couples a layer of the AAF layer system, characterized in that, given a defined direction of magnetization of the antiferromagnetic layer, the magnetic layers of the AAF layer system are saturated in a magnetic field and, afterward, the position of the direction of the antiferromagnetic layer magnetization and the direction of the saturating magnetic field relative to one another is changed, so that they are at an angle &#x3b1; of 0&#xb0;&#x3c;&#x3b1;&#x3c;180&#xb0; relative to one another, after which the saturating magnetic field is switched off.
