An efficient method and a system for controlling access to a location secured by a lock mechanism controlled by a lock control unit, which may provide a high degree of flexibility and a high level of security. The method includes the steps of storing a first access code in the lock control unit, the first access code being indicative of a predetermined access right to the location, and storing a plurality of access codes including a second access code in an electronic key device. Using the electronic key device, access to the location is requested by initiating transmission of the second access code to the lock control unit where the transmitted second access code is compared with the first access code and, if the first access code corresponds to the second access code, operation of the lock mechanism is initiated. The user can edit and rearrange the plurality of access codes to obtain access to a plurality of locations.

A capacitive proximity switch for detecting the change in the capacitance relative to a setpoint capacitance by the approach or retreat of an object in the sensitive area of a proximity switch, especially for use in the door handle of a motor vehicle, provides reliable error detection and error suppression at a fundamentally high sensitivity of the capacitive proximity switch by utilizing an evaluation unit that evaluates a measured value of the change in capacitance over time and depending on the time behavior of the measured value activates changes the operating threshold from a first threshold (which can be caused by a false object coming into or out of the sensitive area of the proximity switch) to a higher second threshold which can be reached only at a relatively greater change in capacitance caused by a target object coming into or out of the sensitive area of the proximity switch.

A system and method for, by means of a mobile terminal, wireless hotel search and selection, reservation/booking, check-in, room access control, check-out and payment services for hotel customers is disclosed. The mobile terminal (1) comprises a mobile telephone and processing unit (23), operating with wireless applications, for wireless communication (2) with a hotel search and reservation server (12) and a reservation/IT system (7) of a selected hotel, and a short-range wireless device (25) for wireless communication (10) with wireless devices (9,16) of door locks (32) and user locating arrangements, respectively.

A wireless key system employs short-range wireless communication to transmit key information from a key device to a lock device. The lock device then authenticates the wireless communication link between the lock device and key device, and unlocks a door or other structure if authentication succeeds. The key information used for authentication may include both a unique address and a shared code. Besides unlocking a door, the system may perform other functions, such as monitoring room occupancy, switching power on and off, and taking safety measures when the key device is moved out of communication range with the lock device.

A two-point locking system for providing controlled access through a doorway is described comprising a controlled deadlatch assembly and a magnetic lock assembly. The controlled deadlatch assembly comprises (i) a deadlatch for selectively latching and unlatching a door, (ii) an input control device for selectively controlling the deadlatch, and (iii) a first wireless transmitter for transmitting a magnetic lock control signal. The magnetic lock assembly comprises (i) a metal housing unit, (ii) an armature plate, (iii) an electromagnetic element coupled to the housing unit and aligned to magnetically engage with the armature plate when selectively electrically energized, and (iv) a wireless receiver capable of receiving the magnetic lock control signal from the wireless transmitter. The magnetic lock control signal will typically disengage the magnetic lock assembly when the controlled deadlatch assembly is unlatched (thus unlocking the door and allowing access) and engage the magnetic lock assembly when the controlled deadlatch assembly is latched (thus locking the door and not allowing access). A second wireless transmitter can also be added to the magnetic lock assembly to communicate to a second wireless receiver at the controlled deadlatch assembly to provide two-way wireless communication between the two locking points.

An apparatus automatically locks the doors of a vehicle based on mutual communications between a portable unit and a vehicle-side control unit. After the doors are closed and locked after all the passengers get off the vehicle, the user of a portable unit unlocks the doors in order to allow a person without the portable unit to fetch something left in the vehicle. After the person opens a door, takes whatever he or she needs, and closes the door, the doors are automatically locked. When a door sensor is operated to unlock the doors, and one of the doors is opened, a memory means stores information indicating that the portable unit is present in a predetermined range outside of the vehicle. If the memory means stores information that the doors are unlocked, then the doors are automatically locked.
