## Background
RELATED APPLICATIONS
This application claims priority from provisional patent application Ser. No. 61/347,461 filed on May 24, 2010 titled Wireless Network System and Method for Lock Indication, the disclosure of which is incorporated herein by reference.
This application is related to patent application serial number U.S. Ser. No. 12/882,236 filed on Sep. 15, 2010 titled AN APPARATUS AND METHOD FOR ELECTRONIC LOCK KEY INDICATOR (hereinafter “lock key indicator application”), the disclosure of which is incorporated herein by reference.
BACKGROUND
The present disclosure relates to tracking the status of a lock in an environment that that includes one or more keys in general, and to providing an indication of the status of a lock corresponding to said keys, being either locked or unlocked.
Quite often, people forget whether they have locked the door in the house, office, or other premises, or not. As a common occurrence—someone may depart a building intending to secure it by externally locking a certain door using its corresponding key, upon departure. However, following his departure, he or she may be unable to recall whether or not they have actually locked the door, securing it by turning the corresponding key into a locked position. Hence, there is a need to provide a reliable, low-cost, convenient device which may be attached to the majority of portable keys, which device shall clearly indicate whether the lock corresponding to said key has been actuated into the lock position or not.
Furthermore, there are cases when there is a need to provide the lock's status to a remote control or display unit, such as a central alarm control unit, for example when a bank or jewelry main office wants to monitor the status of the locks of all branches.
Several inventors have suggested various devices including attachments to standard keys that would hopefully indicate the most recent lock position. However, most of the present inventions describing a certain electro-mechanical attachment to a certain mechanical key do not offer a true indication of the most recent status of the corresponding lock in the case of multiple key-holders using a common lock; e.g.—one key holder may lock the door such that his attached indicator will indicate “lock” status. Subsequently, a second user may unlock the same door; however, the indicator of the first user will still indicate a “lock” status, which clearly does not reflect the true, recent status of the lock. This discrepancy is clearly due to the fact that there is no channel of communication between the devices attached to the keys of the different users. These devices also do not enable the key-holder an automatic update method to provide the status of the lock to a remote control/display unit.
BRIEF SUMMARY
The present disclosure introduces an electronic apparatus and method, included within a housing that can be attached to most of the known keys, providing an indication of the most recent status of the lock corresponding to said key. Said device shall indicate whether the lock was left locked.
The disclosures referenced above introduced an electronic apparatus and method, included within a housing that can be attached to most of the known standard keys, providing an indication of the most recent status of the lock corresponding to said key. Said device indicates to the individual user whether he or she left the lock in a locked or unlocked position.
The present invention enables a reliable indication of the most-recent status of the lock in case of multiple key holders to the same lock. In accordance with a preferred embodiment of the present apparatus, a wireless communication network is established among all individual key-holders of a given lock, such that each key-holder using the attached indicator—housing referenced above is provided with the electronic signals indicating the true most-recent status of the lock as determined by the most-recent activator of the lock. In addition, a central Monitoring system, which includes a Display terminal or terminals, may clearly display the updated status of many individual locks using said wireless network.
In accordance with a preferred embodiment of the present apparatus, each key is provided with an attached housing which includes the electronic components indicating the last lock-position of the lock corresponding to the key in accordance with the teachings of the related applications referenced above, or any other electronic lock-position indicator. A wireless transceiver, included within said housing, is attached to said electronic indicator. Said transceiver transmits a signal to a wireless network, indicating the most recent status of the lock, as indicated by the electronics included in said attached housing. Other key holders have identical housings attached to their keys, which housings include identical wireless transceivers. A central transceiver is located in the wireless network interfacing with a central server-controller. Said server/controller issues update-signals to all key-holders of a corresponding lock indicating the most recent status of the lock as determined by the most recent activator of said lock.
In some exemplary embodiment of the disclosed subject matter, a cellular network may be used such that all key holders are connected to said cellular network via standard cellular phones which they carry. The transceiver included within the key-housing attachment transmits a lock-status signal to the portable Cellular device, using—for example—a standard Blue-Tooth interface. The Cellular device is programmed to transmit the most recent status of the lock, as updated by its Blue-Tooth interface, through the cellular network to said server-controller, which proceeds to update all other Cellular devices corresponding to the specific lock, with the most recent status of the lock. The Cellular devices, through their Blue-Tooth interfaces, proceed to transmit the updated status to the receivers included within the transceivers connected within each Key-housing attachment, such that a most-recent status of the lock is displayed on each of the key electronic indicators. The combination of said cellular device with the electronic key indicator facilitates a low-cost implementation of lock status indication to disperse multiple users holding identical keys of the same lock, without requiring the installation of a costly, gateway and/or server at each lock position. This is facilitated by programming the cellular device to identify the individual key holder, that is identified by a unique code assigned to him, and transmit its most recent lock or unlock action, which action corresponds to the most recent status of the lock, through the cellular network, and/or receive the most recent action by other identical key-holders of the same lock.
In yet another exemplary embodiment in accordance with the disclosed subject matter, said server-controller can be interfaced and programmed to display the lock status of said lock, as well as the lock status of many other locks, each of which is assigned with a unique code identifying a particular lock. Such monitoring apparatus enables updating of a central control in the status of all locks included within a given building, campus, or wider geographic area covered by the cellular network. This feature is applicable also to an environment that includes only a single key. Moreover, since each key holder within the system is assigned a unique code, the central control system can display who actually was the most recent user that opened or closed the lock.
In some other exemplary embodiment of the disclosed subject matter, an Internet network can be used for electronic lock-status indication. An Internet network may be used such that all key holders are connected to said Internet network via portable devices such as standard cellular phones which they carry, or any other mobile terminal, including but not limited to PDA's, Palm Computers, Notebook computers, etc. The transceiver included within the key-housing attachment transmits a lock-status signal to the portable device, using—for example—a standard Blue-Tooth interface’ or a so-called standard Wi-Fi interface, etc. The portable device is programmed to transmit the most recent lock status, through the Internet network to said server controller, which proceeds to update all other devices corresponding to the specific lock, with the most recent lock-status. The portable programmable devices, through their interfaces, proceed to transmit the updated status to the receivers included within the transceivers connected within each Key-housing attachment, such that a most-recent lock status is displayed on each of the key electronic indicators. The combination of said device with the electronic key indicator facilitates a low-cost implementation of lock status indication to dispersed multiple users of the same lock, without requiring the installation of a costly, gateway and/or server at each lock position.
In the Internet network implementation described above, said server-controller can be interfaced and programmed to display the lock status of said lock, as well as the lock status of many other locks, each of which is assigned with a unique code identifying a particular lock. Such monitoring system enables updating of central control in the status of all locks included within a given building, campus, or wider geographic area covered by the wireless network.
In another exemplary embodiment of the disclosed subject matter, each one of the personal cellular and/or portable device transceivers referenced above can be programmed such that each time it receives an electronic signal indicating an unlock (open) and/or lock electronic signal, corresponding to the given lock, from the cellular and/or Internet network, it will cause said transceiver to issue an alarm which may be audible and/or visual—as displayed on the screen of said cellular or other portable device. Said alarm will alert the key-holder to the recent status of the lock.
In another exemplary embodiment in accordance with the disclosed subject matter, whenever a locking or unlocking operation is detected by the lock tracking device, the wireless key unit activates or deactivates an alarm system.
In an exemplary embodiment in accordance with the disclosed subject matter there is provided an apparatus for tracking a status of a lock, comprising: at least one lock tracking device for tracking the status of the lock; and at least one wireless key unit; wherein each of said at least one wireless key unit is connected to one of the at least one lock tracking device, and wherein said at least one wireless key unit includes a transceiver unit for transmitting information obtained from the at least one lock tracking device regarding the status of the lock.

U.S. patent application Ser. No. 12/882,236 filed on Sep. 15, 2010, (hereinafter “lock tracking device application”) the disclosure of which is incorporated here by reference, describes electronic devices and systems, included within a housing that can be attached to most of the known mechanical-access keys, providing an indication of the most recent status of the lock corresponding to said key as determined by the most recent action of the key holder of said key. According to the teachings of said referenced patent-applications, when the key holder inserts the key into the corresponding lock, locking or unlocking the lock, an electronic signal is generated, which signal is fed to an electronic indicator which displays the most recent status of the lock, i.e.—indicating whether said lock was left in a lock or unlock position, as determined by said individual keyholder.
The present disclosure describes electronic devices and wireless communication systems enabling the indication of the most recent status of the lock as relayed to a plurality of several key holders holding keys with attached housings which correspond to said lock, as determined by the most recent activator of said lock, which activator is a member of the group of key-holders.
Referring to FIG. 1A, describing that key 111 includes an electronic key housing 111C that is divided to two schematic units: a lock tracking device 111a and wireless key unit 111b. When further references in the present disclosure are made to the keys (such as 112,-115 or 161-168) it is assumed that a key housing 111c is attached to the key including the lock tracking device 111a and the wireless key unit 111b. 
One embodiment of a lock tracking device is described in greater detail in the Patent Applications referenced above. The electronic key housing in accordance with the present disclosure is modified by an addition of a low-power transceiver unit (hereinafter “wireless key unit”) as described below.
It should be noted that the present disclosure is not limited to the lock tracking device that is described in the lock key indicator application, thus, any other lock tracking device which isszues an electronic signal indicating the most recent status of the corresponding lock can also be used and included within element 111a to which said wireless key unit will be added.
The lock tracking device 111a tracks the key movements and as described in detail in the lock tracking device application, detects clock or counter clock rotations of the key and identifies locking or unlocking of the lock. The lock tracking device is connected to the wireless key unit 111b and provides information about the lock status to the wireless key unit 111b. The wireless key unit 111b transmits the information that was obtained from the lock tracking device by a transceiver unit 440 (shown in FIG. 4)
It should be noted that the figures and description refer to two separate elements 111a 111b in order to describe the apparatus functionality, practically both units 111a and 111b may be integrated in a way that it will not be possible to physically separate them, for example both units may share a common processor or any other component.
The wireless key unit (each one includes a transceiver 440 shown in FIG. 4) included within electronic key housing 111c communicate over relatively short ranges. FIG. 1A shows five keys 111-115 (each key includes the electronic key housing 111c and the lock tracking device 111a and wireless key unit 111b). Several key-holders of said keys are termed “users”. Each user is assigned a unique code—(the code is defined within the electronic key housing 111c) which identifies him- and is equipped with an additional portable electronic transceiver such as, but not limited to, a cellular phone/mobile phone 121, 122, 123, 124 and 125 respectively. The cellular phones 121-125 are just an example and could be replaced by any portable wireless device (hereinafter “portable transceiver device”). Said portable transceiver devices are receiving wireless data from keys 111-115 (the data being transmitted from the wireless key unit 111b that includes a transceiver unit 440) while transmitting and/or receiving information through base-stations 141, 142, which are interconnected among themselves by means of a Wireless Network, 130. The network may, for example be a Cellular network, or an Internet network accessed by the well-known WiFi wireless interface. The most recent user activates lock 116 located in building 131 using key 111. Following said activation, wireless key unit 111b communicates with portable wireless device 121, providing information about the lock/unlocking activity, and then his portable wireless device 121 transmits electronic signals which identify said most recent user as well as the most recent status of lock 116 to the wireless network which includes a server 135 (hereinafter lock status control unit) programmed to store said most recent status of said lock. The server may keep records of all locking/unlocking activities and may keep updated records of the transmissions that were received from each of the wireless key units. Each one of the users can now interrogate said server (lock status control unit) 135, and receive the most recent status of said lock, i.e.—locked or unlocked position. The specific key-housings referenced above are shown as an exemplary embodiment in accordance with this disclosure and can also be replaced by any other electronic device that transmits signals indicating the most recent status of the lock as determined by said key-housings holder.
According to the teachings of this disclosure, the lock tracking device 111a in combination with the wireless key unit 111b, both battery operated, enable the realization of true indication of the lock status to multiple key-holders without the need for a multitude of local servers and/or gateways to be located in each house 131, where lock 160 is located, and without requiring external power to be fed to either said lock or said local gateway/server. Only one central server (lock status control unit) 135 is required as described below.
The wireless system and method according to the present disclosure may, for example, be a cellular wireless network with cellular phones born by each user. Yet another embodiment in accordance with the disclosed subject matter may utilize an Internet network with the well known WiFi interfaces and protocols located in each portable wireless device 121-125 as well as in the network servers, or any other wireless network. The wireless apparatus and method according to the present disclosure may also be a combination of different wireless networks for example one user may use a cellular phone device while another user communicates with a WiFi device wherein both devices are connected to the internet.
