Abstract: A security control module for controlling access through a passageway of a secure control area, comprising an ultra-wideband transceiver configured to establish an ultra-wideband transmission with a mobile device and a processing unit configured to determine a first distance between the security control module and the mobile device by processing signal properties of the ultra-wideband transmission. The security control module is configured to receive a second distance from a further security control module arranged at a spacing distance apart, the second distance being indicative of a distance between the further security control module and the mobile device. The processing unit is configured to determine the relative position of the mobile device with respect to the security control module based on the first and second distance.

Abstract: Device, method, and computer program product for access control, the device comprising an ultra-wideband transceiver (12) connected to a first electronic circuit (11); wherein the first electronic circuit (11) is configured to activate (S1) periodically the ultra-wideband transceiver (12) to receive ultra-wideband transmissions (T) from a mobile device (2), upon reception (S2) of an ultra-wideband transmission (T) from a mobile device (2), to activate the ultra-wideband transceiver (12) to transmit (S3) to the mobile device (2) a reguest message and to receive (S5) from the mobile device (2) a response message, to determine (S6) a distance (d) of the mobile device (2) from the access control terminal (1), using the response message, and to execute access control, if the mobile device (2) is within a pre-determined proximity range (P).

Abstract: Method, device and system for data transfer between a mobile device (3) and a reader device (2), the method of data transfer comprising: transmitting (S3) a request value from an ultra-wideband communications module (1) to the reader device (2); determining (S4) a distance between the ultra-wideband communications module (1) and the reader device (2); generating (S5) a validation value in the reader device using the request value and transmitting (S6) the validation value from the reader device (2) to the mobile device (3), if the distance is smaller than a predefined value; verifying (S7), in the mobile device (3), the validation value; and enabling (S8), in the mobile device (3), further data transfer (S9) between the mobile device (3) and the reader device (2), upon affirmative verifying of the validation value.

Abstract: For simultaneous detection of the state of a locking element (12) and the state of the window or door, a lock (11) or fitting is provided, in which at least one coil (13) is arranged on the face plate (14) or on the strike plate, on the respective outer face thereof, wherein the coil (13) is arranged around the opening for the locking element (12). To determine the state of the door and the state of the bolt, an alternating voltage signal is applied to the coil (13), the impedance of the coil is determined, and said impedance is compared to predetermined values. To increase reliability, successive signals having different frequencies can be applied to the coil (13) and the impedance can be determined at said different frequencies and compared to predetermined values.
