Latest Patents

One of Siegwart's latest patents is a passive infrared detector. This device features a first sensor that generates an infrared signal, representing the temperature difference between a heat source and the surrounding environment. It also includes a second sensor influenced by ambient temperature and an evaluation circuit that processes the infrared signal. The evaluation circuit is equipped with temperature compensation, ensuring that the detector's sensitivity is not directly affected by changes in ambient temperature. Instead, the sensitivity is influenced with a delay or based on the speed of temperature changes.

Another significant patent is for an intrusion detector that incorporates a sabotage surveillance device. This detector consists of a housing containing an infrared device and sensor, along with a detector window that allows infrared radiation to pass through. The device includes an element for focusing the infrared radiation onto the sensor and features a sabotage surveillance mechanism with an infrared transmitter and receiver. The system measures the proportion of radiation reflected from the detector window and that transmitted from the surrounding space. Additionally, the detector may include an ultrasonic device for enhanced security monitoring.
