Alarm system
First Claim
1. An anti-theft alarm system for vehicle wheels, comprising:
- at least one wireless measuring module for determining kinetic state information characterizing the kinetic state of a vehicle wheel on the basis of an acceleration, velocity or oscillation frequency measurement, the wireless measuring module being further configured to be attached to the vehicle wheel, to generate a wireless data transfer signal on the basis of the kinetic state information and transmit the wireless data transfer signal;
at least one adapter configured to attach a wireless measuring module to a middle opening of a rim of the vehicle wheel, the adapter comprising a flange preventing the adapter and the wireless measuring module from being removed from the rim without removing the rim from the vehicle, the adapter and the wireless measuring module being separate from an axle of the vehicle and attachable to the rim before the rim is mounted to the vehicle, the wireless measuring module configured to determine said kinetic state information from a vicinity of the rotational axis of the vehicle wheel; and
at least one wireless central processing unit, which is configured to receive the wireless data transfer signal and execute a predetermined alarm function when the wireless data transfer signal fulfills predetermined conditions indicative of a theft alarm status.
