`OFFLINE LOCK SYSTEM AND METHOD
`THEREOF
`
`CROSS-REFERENCE TO RELATED
`APPLICATIONS
`[0001] This application claims priority under 35 USC §
`120 from U.S. Provisional Application No. 62/275,913, filed
`on Jan. 7, 2016, in the United Stated Patent and Trademark
`Office, the disclosure of which is incorporated herein in its
`entirety by reference.
`
`BACKGROUND OF THE INVENTION
`
`1. Field of the Invention
`[0002] The present general inventive concept relates to an
`offline lock system and method thereof.
`
`2. Description of the Related Art
`[0003] There are various types of locks being used con-
`ventionally to secure buildings and doors within the build-
`ings. Such conventional locks include online locks, wireless
`locks, and offline locks.
`[0004] Online locks are networked with the rest of a
`facility's access control system, so decision-making is done
`in real-time on a central hub, rather than at a door. These
`online locks provide greater capabilities than offline locks,
`including remote management, automatic alerts, and differ-
`ent user access levels. Online locks can be either wired or
`wireless, depending on an end-user's needs.
`[0005] Wireless locks use wireless protocol to communi-
`cate with a system's central hub. Wireless locks provide an
`added level of flexibility, as they can be quickly and easily
`added to an access control solution without the significant
`time investment involved with running wire. An historical
`disadvantage of online wireless locks is that there is greater
`potential of losing system communication with the server,
`which can be a problem when security is a risk.
`[0006] Offline locks are battery-operated, stand-alone
`units, so they don't require wiring to a system's central
`processing unit (CPU). Since offline locks aren't network-
`enabled, they represent a much more affordable solution for
`many end users, and they can be added to an existing access
`control system.
`[0007] At present, offline locks are significantly cheaper
`than online locks. Also, offline locks use significantly less
`battery power than online wireless locks, and therefore
`require less frequent battery replacement.
`[0008] However, offline locks cannot be accessed from a
`central hub, and therefore require a user to come within
`range of the offline lock to change configurations and
`settings thereof. As such, in a building of 200 locks, for
`example, the user would have to come within range of each
`individual lock to change configurations or settings thereof,
`which is inconvenient and time-consuming.
`[0009] Online locks, in contrast, allow a user to make
`changes to configurations and settings thereof from a central
`hub, thereby enhancing convenience for the user, while duly
`saving time. However, since the online wireless locks are all
`connected to a network, they are constantly draining battery
`power, and therefore require frequent battery replacement.
`[0010]
`In sunnnary, online wireless locks are expensive
`and battery-draining, but allow for easy configuration and
`manipulation from a central hub, while offline locks are
`
`cheaper and battery-saving, but do not allow for easy
`configuration and manipulation from a central hub.
`[0011] The expensive online locks (typically $3000 to
`$5000 per door) are most commonly connected by wire/
`cable or wireless (Wi-Fi). As such, "online locks," due to
`wiring or due to wireless (Wi-Fi), currently require power.
`Therefore, electricians are typically required for lock instal-
`lation, system engineers are required to design the system,
`and trained service technicians are required to install long
`wire/cable runs from these on-line locks back to a controller
`or server. Wireless (Wi-Fi) systems are basically no less
`expensive than wired systems because online wireless locks
`require special components, such as repeaters or range-
`extenders, to be installed in strategic areas to keep "powered
`locks" on-line.
`[0012] Currently, there does not exist any other offline
`lock system (such as a BLUETOOTH distribution-type
`system or a BLUETOOTH mesh-type system) that provides
`most of the functionality of an expensive online lock system
`by utilizing offline battery-powered locks, by temporarily
`"waking up" power momentarily to the offline locks to allow
`communication between the offline locks and a server.
`[0013] Therefore, there is a need for an offline lock system
`that allows a plurality of locks to have temporary, direct
`communication to a server through a Lock Updater, such
`that the offline lock system is affordable ($300 to $500/
`door), easily installable, easily updatable, secure, user
`friendly, and energy-efficient.
`
`SUMMARY
`[0014] The present general inventive concept provides an
`offline lock system having functionality of an online lock
`system, while maintaining efficiency and cost-effectiveness
`of a conventional offline lock system.
`[0015] Additional features and utilities of the present
`general inventive concept will be set forth in part in the
`description which follows and, in part, will be obvious from
`the description, or may be learned by practice of the general
`inventive concept.
`[0016] The foregoing and/or other features and utilities of
`the present general inventive concept may be achieved by
`providing an offline lock system, including at least one
`offline lock installed on a door to allow the door to lock and
`unlock, at least one lock updater disposed within a prede-
`termined range of the at least one offline lock to communi-
`cate with the at least one offline lock an access control
`system to communicate with the at least one lock updater
`such that the at least one lock updater transmits information
`to the at least one offline lock to update the at least one
`offline lock.
`[0017] The at least one offline lock may include a sensor
`to sense a predetermined condition of at least one of the door
`and the at least one offline lock, a receiver to receive a signal
`including the information from the at least one lock updater,
`and a transmitter to transmit a signal with other information
`to the at least one lock updater.
`[0018] The at least one offline lock may switch from a low
`power mode to an online mode in response to at least one of
`the sensed predetermined condition and the signal received
`from the at least one lock updater.
`[0019] The at least one offline lock may be updated while
`in the online mode, and the at least one offline lock may
`switch from the online mode to the low power mode after the
`update is completed.

`
`[0020] The transmitter may transmit the signal with the
`other information to the at least one lock updater in response
`to the sensed predetermined condition, and the at least one
`lock updater may transmit the other information to the
`access control system.
`[0021] The predetermined condition may include at least
`one of the door being ajar for a particular time period,
`batteries within the at least one offline lock having low
`power, and an unauthorized user attempting to unlock the at
`least one offline lock.
`[0022] The access control system may select a closest one
`of the at least one lock updater with respect to the at least one
`offline lock that requires an update.
`[0023] The at least one lock updater may communicate
`with the at least one offline lock using BLUETOOTH LOW
`ENERGY (BLE).
`[0024] The access control system may include a storage
`unit to store at least one of information regarding the at least
`one offline lock identification and/or profile data of autho-
`rized users, identification and/or profile data of unauthorized
`users, commands to control user access to the access control
`system, commands to control user access to the at least one
`offline lock, commands to control the at least one offline
`lock, status types of the at least one offline lock, and
`programs to allow control of the at least one lock updater
`and the at least one offline lock, and an input unit to allow
`a user to input information to change a setting of the at least
`one offline lock, update the at least one offline lock, and
`change access information of the at least one offline lock.
`[0025] The offline lock system may further include a
`mobile device to allow a user to access and control the
`access control system remotely.
`[0026] The foregoing and/or other features and utilities of
`the present general inventive concept may also be achieved
`by providing a method of updating an offline lock system,
`the method including transmitting a first signal and first
`information from an access control system to a selected lock
`updater, transmitting a second signal and second information
`via Bluetooth communication from the selected lock updater
`to at least one of a plurality of offline locks, switching the at
`least one of the plurality of offline locks from a low power
`mode to an online mode in response to the at least one of the
`plurality of offline locks receiving the second signal via
`Bluetooth communication, updating at least one setting of
`the at least one of the plurality of the offline locks based on
`the second information received from the selected lock
`updater, and switching the at least one of the plurality of
`offline locks from the online mode to the low power mode
`after the update.

`but is not limited thereto.
`[0051] The ofiline lock 130 may be in a sleep mode until
`it receives a signal to "wake up" from the lock updater 120.
`While the ofiline lock 130 is in the sleep mode, battery
`power is conserved.

`
`[0060] FIG. 3 is a detailed diagram of the lock updater 120
`of FIG. 1, according to an exemplary embodiment of the
`present general inventive concept.
`[0061] The lock updater 120 may include a storage unit
`121, a central processing unit (CPU) 122, a transmitter 123,
`a receiver 124, a Bluetooth transmitter 125, and a Bluetooth
`receiver 126.
`[0062] The storage unit 121 may store data similar to the
`data stored in the storage unit 113 of the ACS 110.
`[0063] The CPU 122 may perform controlling functions to
`determine whether data should be transmitted to the ACS
`110 or the offline lock 130.
`[0064] The transmitter 123 may send signals and infor-
`mation to the ACS 110, and the receiver 124 may receive
`signals and information from the ACS 110.
`[0065] The Bluetooth transmitter 125 may send signals
`and information to the offline lock 130, and the Bluetooth
`receiver 126 may receive signals and information from the
`offline lock 130. The Bluetooth transmitter 125 and the
`Bluetooth receiver 126 may include any type of Bluetooth
`version, including, but not limited to, BLE.
`[0066] FIG. 4 is a detailed diagram of the offline lock 130
`of FIG. 1, according to an exemplary embodiment of the
`present general inventive concept.
`[0067] Each of the plurality of offline locks 130 may
`include a power supply 131, a storage unit 132, a reader 133,
`a receiver 134, a sensor 135, a transmitter 136, a controller
`137, and a locking mechanism 138. The plurality of offline
`locks 130 may each be attached to a door, window, safe, or
`any other object that requires security.
`[0068] The plurality of offline locks may each be powered
`by the power supply unit 131. The power supply unit 131
`may include a removable battery or a plurality of batteries
`being rechargeable or non-rechargeable, or any other power
`source to provide power to the plurality of offline locks 130.
`[0069] The storage unit 132 may include any type of
`storage device used to store data and information, similar to
`the storage unit 113 of the ACS 110. The storage unit 132
`may store information regarding the offline lock 130, iden-
`tification and/or profile data of authorized users, identifica-
`tion and/or profile data of unauthorized users, status types of
`the offline lock 130, and modes of the offline lock 130, but
`is not limited thereto.
`[0070] The plurality of offline locks 130 may all operate in
`a low power mode, which includes a standby mode, an
`offline mode, or a sleep mode. While the offline lock 130 is
`in the low power mode, the power supply unit 131 mini-
`mizes an amount of power output to the offline lock 130. As
`such, any batteries comprising the power supply unit 131
`drain at a minimal rate, thereby conserving power. Accord-
`ingly, the batteries within the power supply unit 131 may last
`upwards of 2 to 3 years, despite the locks being accessed
`dozens of times each day.
`[0071] When the user desires to change a setting, update
`and/or change access information, etc., of a particular offline
`lock 130, the user may input a command (e.g., information)
`into the ACS 110. The ACS 110 may then, through Wi-Fi or
`Ethernet, access a particular lock updater 120 that is within
`a BLE range of the particular offline lock 130. The lock
`updater 120 may then send a signal via BLE to the receiver
`134 of the offline lock 130, which causes the offline lock 130
`to enter into an online mode. The offline lock 130 may then
`receive the information from the lock updater 120, thereby
`allowing the offline lock 130 to be updated with the infor-
`
`mation the user input into the ACS 110. When the offline
`lock 130 finishes receiving the information from the lock
`updater 120, the offline lock 130 returns to the low power
`mode in order to conserve battery power.
`[0072] For example, if an administrator desires to change
`a security-level setting for a particular offline lock 130 from
`low-level security to high-level security (which would grant
`access to only particular predetermined authorized users, for
`example), the administrator may type a corresponding com-
`mand to change the security-level setting for the particular
`offline lock 130, into the input device 112 of the ACS 100.
`Then the transmitter 115 of the ACS 110 may send a signal
`and information corresponding to the security-level setting
`change to the lock updater 120 that is within a Bluetooth (or
`BLE) range of the particular offline lock 130. The Bluetooth
`transmitter 125 of the lock updater 120 may send a signal
`and information to the receiver 134 of the offline lock 130.
`The offline lock 130 "wakes up" in response to receiving the
`signal transmitted from the Bluetooth transmitter 125 of the
`lock updater 120, and as a result, the offline lock 130
`switches from a low power mode (sleep mode, offline mode,
`idle mode, etc.) to an online mode to be able to receive the
`information regarding the changed security-level setting.
`The offline lock 130 may then store the changed security-
`level setting information in the storage unit. Subsequently, to
`preserve battery power, the offline lock 130 switches back to
`the low power mode.
`[0073] The offline lock 130 may also be configured to send
`information to the lock updater 120, based on a user's
`preferences. For example, the sensor 135 of the offline lock
`130 can sense various predetermined conditions of an object
`(i.e., a door, a window, an elevator, etc.) to which the offline
`lock 130 is connected. For example, the sensor 135 may
`sense whether a door is ajar for a particular period of time,
`and send a signal and information to the lock updater 120,
`which then in tum may send a signal and information to the
`ACS 110 to alert the administrator that the door is ajar. Also,
`the offline lock 130 may be programmed to sense when the
`power in the batteries is low, and then may send a signal and
`information to the lock updater 120, which then in turn may
`send a signal and information to the ACS 110 to alert the
`administrator that the power in the batteries is low. Further-
`more, the offline lock 130 may be programmed in advance
`to sense when an unauthorized user is attempting to access
`the offline lock 130, and may send a signal and information
`to the lock updater 120, which then in tum may send a signal
`and information to the ACS 110 to alert the administrator
`that the unauthorized user is attempting to access the offline
`lock 130.
`[0074] Nevertheless, the offline lock 130 remains in the
`low power mode until either the sensor 135 senses the
`predetermined condition, or the offline lock 130 operates in
`the online mode. In other words, the offline lock 130 remains
`in the low power mode until the offline lock 130 enters the
`online mode.
`[0075] All signals and information may be sent from the
`offline lock 130 to the lock updater 120 via the transmitter
`136.
`[0076] The controller 137 may control various compo-
`nents of the offline lock 130. For example, the controller
`may control the transmitter 136 to transmit information to
`the lock updater 120, the locking mechanism to lock/unlock
`the offline lock 130 based on information received from the
`reader 133, or any other function of the offline lock 130

`received by the lock updater 120 in response to a command
`input by the user at the ACS 110. The controller 137 may
`include a central processing unit (CPU), or alternatively,
`may be part of a printed circuit board (PCB).
`[0077] A plurality of different type of settings may be
`input into the ACS 110 to control the plurality of ofiline
`locks 130, such as a Lockdown setting, a Blacklist setting
