    Abstract: It is provided a method for determining whether a portable key device is located inside or outside a metal door. The method is performed by a credential communication device and comprises the steps of: obtaining a first time-of-flight, ToF, measurement between a first antenna and the portable key device, wherein the first antenna is located on the outside of the metal door; obtaining a second ToF measurement between a second antenna and the portable key device, wherein the second antenna is located on the inside of the metal door; and determining the portable key device to be located on the outside of the metal door when the first ToF measurement is less than the second ToF measurement by an amount which is greater than a threshold value.

    Abstract: It is provided an electronic lock for selectively locking a barrier to a surrounding structure. The electronic lock comprises: a locking bolt, a housing comprising metallic material, wherein the housing comprises a through-hole through which the locking bolt can pass; and a wireless communication module. The housing comprises a cut-out forming a slot antenna, wherein the wireless communication module is connected to the housing and thus the slot antenna. The slot antenna is formed on the same surface of the housing through which the locking bolt can pass.

    Abstract: A method is provided for controlling an operational state of a sensor device for break-in detection. The method is performed in the sensor device and comprises the steps of: determining, while in a low-power state, that a wake-up condition is true when a vibration measurement associated with a barrier is greater than a wake-up threshold; transitioning, when the wake-up condition is true, to an active state; determining, while in the active state, when an activity condition is true, the activity condition being based on vibration measurements associated with the barrier; increasing the wake-up threshold, and transitioning to the low-power state when the activity condition is not determined to be true within a first duration while in the active state; and decreasing the wake-up threshold, when the sensor device stays in the low-power state longer than a second duration.

    Abstract: It is provided a method for determining when a break-in attempt is in process. The method is performed in a break-in determiner and comprises the steps of: determining that a first vibration condition is tme when a vibration parameter associated with a barrier is greater than a first threshold, wherein the first vibration parameter is obtained from measurements from an accelerometer; determining whether an acceptable activity condition is tme or not, such that the acceptable activity condition is true only when there is an auxiliary signal indicating acceptable activity comprising determining that the acceptable activity condition is tme only when a time difference between determining that the first vibration condition is true and receiving the auxiliary signal is less than a threshold duration; and determining that a break-in attempt is in process when the first vibration condition is tme and the acceptable activity condition is false.
