Abstract: An apparatus for detecting the position of window handles or door handles, the apparatus including a magnetic-field sensor and a microcontroller unit, the microcontroller unit being designed to read out data from the magnetic-field sensor, to record a magnetic fingerprint for at least one window-handle/door-handle position, and to detect the at least one window-handle/door-handle position by comparing data of the magnetic-field sensor with the recorded magnetic fingerprint.

Abstract: Executing a FOTA (firmware over the air) method in a LoRa network having low throughput and low power. the transceivers used in the end nodes and in the LoRa gateway are capable of selecting a certain frequency channel and deactivating the LoRa mode. If the spread-spectrum LoRa mode is deactivated, both transceivers at the end node and the gateway function instead using a basic FSK (frequency-shift keying) modulation scheme. This modulation scheme is capable of providing a higher data rate at the expense of reducing the “path balance,” which indicates how much attenuation the transmitted signal may sustain while still being able to be decoded at the receiver. When using the FSK modulation scheme at a high data rate, a FOTA method may be easily carried out, since the end node must have its receiver activated only for a short time.

Abstract: Radiometric imaging for scanning a scene includes a radiometer for detecting radiation emitted in a predetermined spectral range from a spot of the scene and for generating a radiation signal from the detected radiation. Spot movement circuitry effects a movement of the spot, from which the radiation is detected, to various positions. Control circuitry controls the spot movement circuit to effect the movement of the spot from one position to another position so that radiation is detected at a number of spots distributed over the scene. The number is lower than the number of pattern signals of the high-density signal pattern and the radiation signals generated from the radiation detected at the number of spots form a low-density signal pattern. Processing circuitry processes the radiation signals of the low-density signal pattern and generates the high-density signal pattern by applying compressive sensing to the low-density signal pattern.
