1. An arrangement for controlling a component in a vehicle based on contents of a passenger compartment of the vehicle, comprising:
- at least one wave-receiving sensor arranged to receive waves from the passenger compartment;
a processing circuit coupled to said at least one wave-receiving sensor and arranged to remove at least one portion of each wave received by said at least one wave-receiving sensor in a discrete period of time to thereby form a shortened returned wave; and
a processor coupled to said processing circuit and arranged to receive data derived from the shortened returned waves formed by said processing circuit, said processor being arranged to generate a control signal to control the component based on the data derived from the shortened returned waves formed by said processing circuit.

Abstract
Arrangement and method for controlling a component in a vehicle in which at least one morphological characteristic of an occupant is measured and a current position of at least a part of a seat on which the occupant is situated is obtained. The component is controlled based on the measured morphological characteristic(s) and the current position of the seat. The component may be an occupant restraint device, such as an airbag whose inflation, deflation and/or deployment direction is/are controlled.

43. A method for generating an algorithm capable of determining occupancy of a seat;
- comprising the steps of;
mounting a plurality of wave-receiving sensors in the vehicle;
obtaining data from the sensors while the seat has a particular occupancy;
forming a vector from the data from the sensors obtained while the seat has a particular occupancy;
repeatedly changing the occupancy of the seat and for each occupancy, repeating the steps of obtaining data from the sensors and forming a vector from the data;
modifying the vectors by removing at least one portion of the wave received by each sensor during a discrete period of time; and
generating the algorithm based on the modified vectors such that upon input from the sensors, the algorithm is capable of outputting a likely occupancy of the seat. - View Dependent Claims (44, 45, 46, 47, 48, 49, 50)
