  • the controller is configured to communicate with a "Key position sensor module” that is responsible for detecting vertical/horizontal position of an associated key.
  • the senor is a proximity sensor or a light sensor or contact sensor or a magnetic sensor.
  • the senor is coupled to an analog to digital converter reporting data to the controller.
  • said predefined distance is in a range of 1 to several millimeters whereas said key still remains partially inserted in said lock.
  • said system further comprises by a push mechanism configured to return the key to a fully slid-in state.
  • these quantities take the form of electrical or magnetic signals capable of being stored, transferred, combined, compared, and otherwise manipulated in a computer system.
  • these signals are referred to as bits, packets, messages, values, elements, symbols, characters, terms, numbers, or the like.
  • a computer-readable (storage) medium typically may be non-transitory and/or comprise a non-transitory device.
  • a non-transitory storage medium may include a device that may be tangible, meaning that the device has a concrete physical form, although the device may change its physical state.
  • non-transitory refers to a device remaining tangible despite a change in state.
  • example means serving as a non-limiting example, instance, or illustration.
  • terms "for example” and “e.g.” introduce a list of one or more non-limiting examples, instances, or illustrations.
  • An electronic lock mounted on the inside is configured to monitor its state but is typically not configured to monitor the other side of the lock, where the second key may be used.
  • the inventor has observed that while using the first (typically outside) key, the second, inner key may be pushed back by a small distance (typically fraction of a millimeter to few millimeters) while still remaining partially inserted in the respective lock.
  • the sliding out of the second, inner key is caused by the insertion of the other, first key in said lock in a keyhole opposite to the keyhole in which the key controlled by said electronic lock is inserted (typically the second, inner key).
  • Detection of such displacement of the inner (second) key may be therefore used to avoid reporting false lock states by the electronic lock.
  • Such detection of a sliding out, of the respective second key, by a predefined distance amount (this distance may depend on the lock type (e.g. in a range of 1 to several millimeters such as 0,75-5 mm) and may be a configurable parameter of the system) may then be reported to a user and/or the electronic lock may thereafter attempt to detect the state of the lock, for example by turning its key and detecting whether the lock is in an open or locked state.
  • the electronic lock may be configured to always keep the inner key in a vertical or horizontal position, inserted in the lock on the inside.
  • Fig. 1 presents a diagram of the system according to the present invention.
  • the system comprises a data bus 101 communicatively coupled to a memory 104. Additionally, other components of the system are communicatively coupled to the system bus 101 so that they may be managed by a controller 105.
  • the memory 104 may store system configuration and/or computer program or programs executed by the controller 105 in order to execute steps of the method according to the present invention.
  • An electronic lock 107 may be controlled by the controller 105 and execute physical tasks related to control of an associated key.
  • Said electronic lock 107 typically comprises an appropriate motor configured to rotate a key under its control.
  • a wireless communication module 106 may be implemented in order to allow the controller 105 to communicate events related to the electronic lock 107.
  • the controller 105 may control transmission of messages/notifications related to locking or unlocking of the door lock being controlled by said electronic lock 107.
  • Exemplary wireless communication methods include Zwave, Bluetooth, ZigBee, WiFi, or the like.
  • the controller 105 is in communication with at least one sensor 103 configured to detect sliding out and sliding in of a key controlled by said electronic lock 107.
  • the sensor 103 may be implemented using different approaches such as a proximity sensor, a light sensor, contact sensor a magnetic sensor or the like. Such sensor 103, depending on needs, may be coupled to an analog to digital converter that will in turn report data to the controller 105.
  • the controller 105 may also communicate with a "Key position sensor module" 102 that is responsible for detecting vertical/horizontal position of an associated key.
  • a “Key position sensor module” 102 that is responsible for detecting vertical/horizontal position of an associated key.
  • Such sensor may comprise multiple sensors such as accelerometers, magnetic field encoders or optical encoders.
  • Fig. 2 presents a diagram of the method according to the present invention.
  • the process starts with known state of the key 2 controlled by the electronic lock 107, wherein said key is fully inserted in said lock (which may be detected appropriately by the sensor 103).
  • the system at this state is also aware of the current lock 3 state, that is whether it is locked or unlocked.
  • the method starts at step 201 from detecting, using said sensor 103, the state of the key under control (typically the inner key).
  • the information, read from the sensor 103 is matched against a predefined condition (which may be said predefined distance amount) in order to determine whether the key has been partially slid out of the lock while still remaining partially inserted in the respective lock.
  • a predefined condition which may be said predefined distance amount
  • the system moves to a wait state 208 and back to continue monitoring the information reported by said sensor 103.
  • the system awaits elapsing of a predefined time condition.
  • the purpose of the wait state 208 is to allow periodical key monitoring and thus to reduce power consumption of the whole system.
  • step 203 it continues to monitor, using said sensor 103, whether the key is slid back into its previous position.
  • the wait state 205 may be in a range of 500ms to 1000ms while the timeout of step 206 is preferably in a range of 2s to 4s.
  • step 204 If in the step 204 the system detects that the controlled key is slid in back to its position, it is assumed that the other key has been removed and the controller 105 performs an action or actions of step 209 according to its configuration.
  • a purpose of the wait state 205 is similar to 208, that is, it enables periodical key monitoring and helps reducing power consumption of the whole system.
  • timeout 206 A purpose of the timeout 206 is twofold. This timeout allows a person, using the other key (typically outer key), to open/lock and remove the respective key. If after such timeout the monitored key (typically the inner key) is still slid out it may be assumed that the user has forgotten to take the other key.
  • the other key typically outer key
  • Such situation is critical for safety as it also prevents the electronic lock 107 from locking the lock from the inside (using the key which is under its control). Thus, a user and/or other device are preferably notified.
  • the respective time values may be configuration parameters of the present system and may be stored in the memory 104.
  • Actions of step 209 undertaken by controller 105 may comprise several steps like verifying the lock state and/or generating notification to user and/or sending notification message(s) to an external device and/or returning the lock to its previous position and others. These actions may be preprogrammed or configured by a user. Otherwise, the system returns to step 201.
  • the controlled key is returned to a fully slid-in state by a suitable push mechanism such as a spring.
  • An action of lock state verification from step 209 may be executed by suitably rotating of the key similarly as a human operator would do (i.e. the system is aware whether the lock is a right/left lock and whether key rotation left or right sets the lock to its locked state).
  • step 209 In case verification action of step 209 results in that the lock's sate has changed, a user (or other devices such as a smart home gateway) may be notified of the new lock state or the controller 105 may set back the lock to its previous state. To this end, the controller (105) may generate appropriate notification message(s). Clearly, the state of the lock (3) is updated in the electronic lock so that the controller (105) is aware of the current state.
  • Fig. 3 presents an example of a system of the present invention with the inner key 2 slid in and the outer key outside of the lock.
  • a system according to the present invention 6 having a sensor 7 of the inner key 2 wherein information reported by the sensor is provided to the controller 105.
  • Insertion of the outer key 1 to the lock cylinder 3 will result in sliding out of the inner key 2 and a change of distance A to distance B (smaller than A) shown in Fig. 4 .
  • the inner key 2 When the outer key 1 has been removed, the inner key 2 may be inserted into the cylinder lock 3 with a use of a pusher 4 and a spring 5. This allows to execute actions from step 209 of the method according to the present invention.
  • the present invention prevents reporting false states by locks coupled to electronic systems and thus makes operation of electronic locks more reliable and error-free. Therefore, the invention provides a useful, concrete and tangible result.
  • the invention uses a sensor to detect physical elements as well as processes responses from such sensor in order to improve reliability of electronic locks. Hence, the machine or transformation test is fulfilled and that the idea is not abstract.
  • the present invention may take the form of an entirely hardware embodiment, or an embodiment combining software and hardware aspects that may all generally be referred to herein as a "circuit", “module” or “system”.
  • the present invention may take the form of a computer program product embodied in any tangible medium of expression having computer usable program code embodied in the medium.
