Abstract: A dielectric lens device for shaping a radar beam includes a first and a second plano-convex cylindrical dielectric lens member and a plane-parallel dielectric substrate. The two plano-convex cylindrical dielectric lens members are arranged with their plane surfaces towards a same surface of the plane-parallel dielectric substrate. The plano-convex cylindrical dielectric lens members are interconnected to the plane-parallel dielectric substrate in a material fit.

Abstract: A radar sensor system and method for ascertaining whether an unattended child is present within an automotive vehicle. The radar sensor system carries out the method and includes a transmitter, at least one sensor, and processing circuitry. The method includes the steps of: illuminating at least one occupiable position within the vehicle with radiation of multiple frequencies; generating radar sensor signals from reflections of the transmitted radiation, a plurality of the radar sensor signals corresponding to different frequencies; and operating the processing circuitry for generating and determining if a first indicator value indicative of motion in the occupiable position satisfies a first predetermined criteria and, if so, generating and determining a second indicator value indicating a degree of repetitive pattern within the radar sensor signals, and determining presence of an unattended child in the vehicle if the second indicator value satisfies a second predetermined criteria.

Abstract: A vehicle seat sensor unit includes a seat occupancy sensor configured for wirelessly communicating with a control unit, at least one first seat detection sensor member and at least one second seat detection sensor member. The first seat detection sensor member is arrangeable in one out of a lower vehicle seat portion of a vehicle seat that is mountable in a vehicle in a removable manner, and a vehicle cabin floor, and the second seat detection sensor member is attachable to the other one of the lower vehicle seat portion and the vehicle cabin floor. The first seat detection sensor member and the second seat detection sensor member are configured to physically interact if mutually arranged within a specific distance. The physical interaction results in a detectable change of a status of at least one out of the first seat detection sensor member and the second seat detection sensor member.

Abstract: A method for 3D imaging of an actively illuminated target region includes emitting intensity-modulated light at a variable modulation frequency into the target region, the emitted light is scattered/reflected in the target region depending on the optical properties of the objects or beings present therein, a scattered and/or reflected fraction of the light is detected during an integration time interval by phase-sensitive integration in each pixel of an imaging sensor, the modulation phase between the emitted and the detected light is determined and spatially resolved, and distance information is calculated based on the spatially resolved modulation phase and an average frequency of the modulation frequency.
