Abstract: It is provided a method for synchronising data between a shore-side access control database (4) and a ship-side access control database (6). The method comprises: determining (140) any modifications to data in the shore-side access control database (4); determining (40) any modifications to data in the ship-side access control database (6); transmitting (142) a shore modifications message (20), indicating the modifications to data in the shore-side access control database (4), to a ship-side server (5), operatively connected to the ship-side access control database (6); updating (46) the ship-side access control database with the shore-side modifications; transmitting (44) a ship modifications message (21), indicating the modifications to data in the ship-side access control database (6), to a shore-side server (3), operatively connected to the shore-side access control database (4); and updating (146) the shore-side access control database with the ship-side modifications.

Abstract: It is provided a method for enabling determination of proximity of a mobile device (2a, 2b) to a beacon device (3a). The method is performed by a proximity determiner (1) and comprises the steps of: determining a set of beacon devices (3a-e) being detectable from the mobile device: obtaining beacon measurements of one or two beacon devices in each pair: generating a two-dimensional graph based on the beacon measurements: obtaining device measurements of signal strength of beacons from the beacon devices in the set of beacon devices: finding an optimum in a space defined by the two-dimensional graph; and determining the most probable position of the mobile device in the graph based on the optimum.

Abstract: It is provided a method for enabling determination of proximity of a mobile device (2a, 2b) to a selected proximity determiner (3a). The method comprises the steps of: determining a base set of proximity determiners (3b-e) whereby an enlarged set of proximity determiners is defined as the selected proximity determiner and the base set of proximity determiners; receiving beacon measurements of signal strength of other proximity determiners in the enlarged set of proximity determiners; generating a two-dimensional graph based on the beacon measurements; receiving respective device measurements indicating signal strength of a signal from the mobile device at each proximity determiner in the enlarged set of proximity determiners; finding an optimum in a space defined by the two-dimensional graph; and determining the most probable position of the mobile device in the graph based on the optimum.

Abstract: It is provided a method for providing a credential set to a credential carrier for gaining access to a physical space. The method is performed in a credential provider and comprises the steps of: preloading a plurality of credential sets from a server into a local memory, each credential set being usable to gain access to a physical space and each credential set comprising a first validity time; wherein, when a network connection between the credential provider and the server is unavailable, performing the following steps: obtaining a request to provide a credential set for a physical space; retrieving a credential set from the local memory, the credential set being usable to gain access to the physical space indicated in the request; and providing, as long as the first validity time of the credential set has not expired, the retrieved credential set to a credential carrier.

Abstract: Methods, systems, and devices for controlling access within a multi-facility room are provided. More specifically, a guest of the multi-room facility is allowed to remotely confirm reservations to the facility as well as bypass the front desk of the multi-room for check-in purposes. At a location within the facility, the guest is allowed to confirm their arrival, check-in, and have their access credential written with personalized access data that may be useable for the duration of the guest's stay.

Abstract: Methods, systems, and devices for managing energy consumption in multi-room facilities are provided. In particular, intelligent mechanisms for determining a room occupancy state and then for managing energy settings of that room are provided. Some logic for implementing these mechanisms may be provided in an in-room device, such as a motion detector, thermostat, door, lock, television, set top box, etc.
