The invention relates to a method for motion detection inside and / or outside a vehicle (F) by means of a sensor system (S) having: a first BLE sensor (S1); and a second BLE sensor (S2), wherein one of the two BLE sensors (S1, S2) is used as initiator and the other of the two BLE sensors (S1, S2) is used as reflector in order to perform a BLE channel sounding, in particular comprising two distance measurement methods: a primary phase-based distance measurement (PBR); and a secondary round-trip-time (RTT)-based distance measurement, and the measured values in the BLE channel sounding are used for enabling motion detection inside and / or outside the vehicle (F), in particular without using a mobile device and without using further sensors, such as UWB sensors and / or ultrasonic sensors.

This utility model discloses a yarn hook component that reduces the coefficient of friction with the main body, specifically relating to the field of yarn hook technology. It includes a first guide frame and a second guide frame. A telescopic guide assembly is provided at the bottom of the first guide frame, and a first guide wheel is movably installed inside the first guide frame. This utility model, by providing the first and second guide wheels, forms a complete hook body with the first and second guide frames, allowing the yarn to pass through and assisting in guiding the yarn. The first and second guide wheels are movably installed on the inner sides of the first and second guide frames, respectively. When the yarn passes through the inner sides of the first and second guide wheels and comes into contact with them, the rolling first and second guide wheels help reduce the frictional force when the yarn moves, minimizing the impact on the yarn and enhancing the protective properties of the yarn hook during use.
