An access control device comprises at least one transit authorization request device, such as an ID sensor activated by access card or badge or a biometric sensor (fingerprint, retina), said transit authorization request device to be activated by a person requesting authorization to pass through said passageway or doorway and a presence detection and tracking device for detecting the presence of a person in the vicinity of said passageway or doorway and for tracking the movement of a person within or through said passageway or doorway. According to the invention, the access control device further comprises a control unit configured for assigning a virtual transit ticket to a person after authorization to pass through said passageway or doorway has been granted to said person, said virtual transit ticket being representative of the transit privileges granted to said person, i.e. the privileges regarding the transit direction through said passageway of doorway, and for controlling said presence detection and tracking device to track the movement of the person with the virtual transit ticket with respect to the granted transit privileges, said control unit comprising a processing module with a configurable decision table for generating an output control signal based on an output signal of said at least one transit authorization request device and an output signal of said presence detection and tracking device, said output control signal to be used for the controlling of the passage of persons through a passageway or a doorway.

Configurable access control sensing device

A method for the determination of a physical property parameter of a seat passenger includes getting a reading of at least two parameters from an occupancy sensor; plotting a probability vector which shows, for each value of the physical property, the probability to cause the readings of the at least two parameters; and correlating the physical property parameter to the range of values of the probability vector with the highest probabilities.

Method for the determination of parameters of a seat passenger

A method for classifying an occupancy status of a vehicle seat includes associating a filtered class to a specific seat occupancy status based on a plurality of successive readings of at least one parameter value of a seat occupancy sensor, including the steps of: 1) determining an actual value of a first parameter of the seat sensor and associating an actual class to the actual value of the first parameter; 2) storing the actual class in a buffer, and deleting the oldest stored class; 3) plotting a confidence parameter indicative of the reliability of the actual class; 4) setting an updated filtered class to equal (i) an average of the classes stored in the buffer, if the confidence parameter is smaller than a first confidence threshold value, or (ii) the previously determined filter class, if the confidence parameter is greater than or equal to the first confidence threshold value.

Method for the classification of an occupancy status of a vehicle seat

A method for the classification of an occupancy status of a vehicle seat, where occupancy profiles from an occupancy sensor are recorded and evaluated and the classification of the actual occupancy status is determined. The method includes, when the system power is turned off, storing the last determined class and the last recorded profile into a non-volatile memory; when the system power is turned on, comparing the first recorded profile with the profile stored into the non-volatile memory; and if the likeness of the first recorded profile and the profile stored in the non-volatile memory exceeds a specific threshold, setting the actual class to equal the class stored into the non-volatile memory.
