Title: Luggage Tracking Device, Systems and Methods

Description:
FIELD OF THE INVENTION 
     The present invention relates to luggage tracking and monitoring devices, systems and methods. 
     BACKGROUND OF THE INVENTION 
     According to the 2014 annual SITA Baggage Report, the World Tracer statistics reported that there were 3.13 billion airline passengers in 2013, representing a 5.1% increase over 2012. As more individuals around the globe transition into the middle class, this figure will only increase and, despite efforts to reduce the number of mishandled luggage, a huge amount of luggage invariably goes missing every year. 
     In 2013, 21.8 million pieces of luggage were mishandled, a figure that equates to 6.96 bags per 1,000 passengers, with 3.3% of items never being recovered. These figures cost the aviation industry 2.09 billion in 2013 alone. 
     According to the 2015 annual SITA Baggage Report, there were 3.3 billion airline passengers in 2014, representing a 5.4% increase over 2013. As more individuals around the globe transition into the middle class, this figure will only increase and, despite efforts to reduce the number of mishandled luggage, a huge amount of luggage invariably goes missing every year. 
     In 2014, 24.1 million pieces of luggage were mishandled, a figure that equates to 7.3 bags per 1,000 passengers, with 5.5% of items never being recovered. These figures cost the aviation industry 2.4 billion in 2014 alone. 
     This is a known problem within the airline industry; however, no effective solutions have been implemented. Airports and airlines are beginning to adopt radio-frequency identification (RFID) models to aid the tracking of luggage, but these tracking capabilities are restricted to being within the range of a scanner. 
     Individual tracking devices have also been developed as a means of informing end users of their luggage location, but again, these services are unreliable, limited to only transmitting information pertaining to physical location and exposed to potential damage. In addition, attempts have been made to enhance automation and efficiency in regards to the luggage transferring process, such as pick up from home services with accompanying baggage tag systems, which are also imperfect due to the increased probability for further luggage mishandling. 
     U.S. Pat. No. 8,742,922 B2 discloses a luggage-tracking device that is configured to be attached to a piece of luggage and a location unit to determine a current location of the device. This device has only locating capabilities and is susceptible to unauthorized access, being attached to the outside of a luggage article hence providing users with access to internal components of the tracking device from the outside. Having a device placed externally also increases the chances for luggage mishandling. 
     U.S. Pat. No. 7,535,358 B2 discloses an electronic luggage tag that uses GPS technology to both track luggage, and record the specific times and places that a specific piece of luggage is opened. This device is lacking automation and requires the user to replace batteries and also remember to input the device into an appropriate location, i.e. where functionality of the device is exposed to sufficient lighting for sensor functionality to work, within a luggage article every time a traveller uses the item. In addition, to provide the device functionality requires high power usage. Furthermore, the device does not provide adequate information as to the reason a luggage article may have been manipulated. 
     U.S. Patent Publication No. 2014/0151173 discloses a luggage article with a display and a communication system for luggage articles. The design consists of numerous functions, such as cameras, internal and external display units, numerous environmental sensors and weighing scales, quickly deplete the product&#39;s battery life, even if a large power source is included. This will also enhance probability of increased levels of damage, increases the weight of a luggage article (which is becoming an increased concern for airlines and airports), in addition to being extremely intrusive on luggage specifications and therefore requires sufficient resources to enable such functionality. 
     Moreover, passengers currently have limited control over the luggage process and recent surveys suggest that travellers now seek more engagement in the luggage handling process when travelling. According to SITA&#39;s 2013 Passenger IT Trends Survey, the need for self-service has increased; with over 50% of these individuals stating that they would actively use baggage status information if it were available to them. In 2014, a survey indicated that half of all passengers see room for improvement with their travel experience, with over 48% of these individuals stating that their most frustrating aspect of travel is managing their baggage. 
     A further key concern for passengers during transit is luggage security. Passengers are often required to part with their luggage and, in so doing, have limited control of who may gain access to their luggage. For example, when an airline passenger wishes to place an item of luggage in the aircraft hold, the passenger must hand the luggage over to the airport security so that the luggage can be screened and transported to the hold. An airline passenger therefore no longer has any control over who may access their luggage and places a great deal of trust in airport staff. Another example is when a passenger is on a train or a coach and must store their luggage in a location remote from their seat which is out of sight. In such circumstances, the passenger must trust that members of the general public will not attempt to gain access to the luggage and steal items therefrom. A further example is when a passenger is temporarily separated from their carry-on at security checkpoints, such as immigration, and also while on an aircraft when the carry-on is stowed away in the overhead bin. 
     Unfortunately, members of luggage handling staff and the general public can sometimes succumb to temptation and gain entry to items of luggage in order to steal valuables. Whilst most modern day luggage comprise locking mechanisms to prevent unauthorised access, sometimes the locks can be bypassed either by force or some other mode of access. 
     In the United States of America, for example, it is a requirement that the Transportation Security Administration (TSA), which screens every passenger&#39;s luggage before it is placed on an airplane, has access to luggage without the passenger being present. This is because there are instances when airport security need to physically inspect a piece of luggage for security purposes. As a consequence of this, the TSA has worked with several companies to develop locks that can be opened by airport security personnel using universal “master” keys so that the locks do not have to be cut. However, this provides airport security personnel with easy access to a passenger&#39;s personal, and potentially valuable, belongings. 
     Therefore, there are several instances during transit in which an unauthorised individual may gain access to a passenger&#39;s luggage without the passenger being present. Particularly for air travel, it is important that a passenger can identify when their luggage has been accessed and when an item may have been stolen. Identifying a more precise period of time in which luggage may have been stolen can help to identify who handled the luggage and, therefore, narrow down the list of possible suspects. In addition, to make a claim against an airline or transport administration, a passenger is typically required to report a theft or incident whilst they are still airside. The moment a passenger leaves, the problem becomes a police matter and not an airline or airport problem. Quickly identifying a luggage breach and/or theft can therefore help to safeguard a passenger&#39;s rights. 
     In view of the above, there is a need for an apparatus and system for monitoring the unauthorised access of an item of luggage and alerting the owner of the luggage of any such instance of unauthorised access. 
     SUMMARY OF THE INVENTION

This data may then be configured and transmitted across high priority GSM networks using USSD messaging, or any other form, thereby incurring much lower roaming charges than standard network charges. The use of USSD messaging extends the wireless communication reach of the tracking device and lowers power consumption. 
     The USSD messages may be sent to an Application Programming interface (API) end point that enables communication between the device and a chosen server or uniform resource locator (URL). This end point may then process and configured the data in a format that displays a summary of an articles location and condition on smart phone applications or any other form. Changes in predefined conditions may also be configured to alert travellers of sudden state changes through the use of push notification systems or any other form. 
     The tracking device may be strategically placed in a luggage article&#39;s interior to advantageously be connected to numerous luggage article-locking mechanisms. 
     The luggage tracking device may also include a power source that is configured to automatically switch between online and offline mode during take-off, taxiing and landing, in addition to when a luggage article is inactive and subject to no movement over the course of a predefined time period. This may be achieved through the use of sensor units that can detect motion.

     DETAILED DESCRIPTIONS OF THE PREFERRED EMBODIMENTS 
       FIG. 1  depicts luggage tracking device  100  that is housed  101  inside a luggage article  140 , such that it is not accessible from the outside of the luggage article. This device directly integrates with the luggage article&#39;s locking mechanism  130  during the manufacturing stage of a luggage article  140 . 
     It would be appreciated that a luggage manufacturer may appropriately select the location of the tracking device, and attached using conventional means in the art such as glue, screwing or any other method that prevents a luggage lock-tracking device  100  from being removed. 
     A number of locations of the tracking device would be possible. Referring to  FIG. 4  a luggage tracking device  100  is placed and permanently attached directly behind the locking mechanism  130  of the luggage article  140  as an integral component or in another interior location. 
     Alternatively, a luggage-tracking device  100  may also be included in a luggage article with multiple locking mechanisms  130  to connect all locking mechanisms  130 , such as illustrated in  FIG. 5 . 
     The tracking device is considered in more detail in  FIG. 2  which depicts the luggage-tracking device&#39;s  100  printed circuit board (PCB)  110  mechanically supporting and electrically connecting components. 
     The PCB  110  may support a GSM module unit  116  that incorporates a controller unit  115 , for example a central processing unit (CPU) or accelerated processing unit (APU), a transmitter/receiver unit  113 , for example a GSM/GPRS component, and a memory unit  112 , for example a read and write MCU that may be configured for storing information retrieved from sensors  111  and transmitter/receiver units  118 . 
     The PCB  110  may also support sensors  111 , for example g-sensors configured to disable or enable transmitting capabilities respectively during take-off, taxiing and landing. These sensors  111  may also be configured to recognize non-movement for a predefined period of time that automatically communicates an instruction to switch the luggage-tracking device  100  into “sleep mode”, also disabling transmitting capabilities. The luggage-tracking device  100  may then return to “online mode” once the luggage tracking device  100  data source, i.e. sensors  111 , detects movement. 
     Optionally, the PCB  110  may also include other sensors such as push button sensors to determine tampering alerts and TSA lock and combination unlock/lock states. A further transmitter  113 , may be included, for example a component configured to transmit/receive GPS signals, together with an antenna-tuning unit  114 . This antenna unit  114  would improve power transfer between transmitting units  113  and its antenna to amplify an electrical signal for transmission to one or more remote electronic communication devices, with the overall tracking device being powered by a power circuit unit  117 , for providing power to components of the PCB  110 . 
     All components of the PCB  110  may be coupled with the GSM module unit  116 , with the antenna-tuning unit  114  being coupled with a transmitting unit  113 . The transmitting unit  113  is further coupled with the GSM module unit  116 . 
     The luggage-tracking device  100  may be provided electricity from a power source unit  120 . In particular it would be appreciated that a battery could provide electronic power to a power circuit unit  117  coupled with a transmitter unit  113 , hence the battery  120  ultimately powering all components within the PCB  110  and locking mechanisms  130 . 
     When a user first purchases a luggage article that has an integrated smart luggage lock tracking device  100  the user may need to sign up to the accompanying online platform and register their product in order to activate the device  100 . According to various exemplary embodiments, the device may include a data port that provides activation functionality and a means to recharge the luggage-tracking device  100 . 
     The end user may then be required to download an online application, i.e. smart-phone app or any other form, to access information recorded, received, processed, stored and transmitted by the luggage device  100 . 
     All information may be preconfigured to be transmitted on a real time basis at predefined intervals with online platforms. 
     Optionally the device may be programmed, at the user&#39;s discretion, to enable alert functions, in order to keep end users informed of any sudden predefined state changes, i.e., TSA or combination lock/unlock, tampering attempts, airplane mode, sleep mode, offline (actuable by a switch) and online mode. 
     According to various exemplary embodiments, the luggage tracking device  100  may be provided with a backup reset button to ensure the luggage tracking device  100  is working appropriately, for example turning on and off and transmitting. 
     In a further exemplary embodiment, if data is unavailable from GPS signals the device  100  will attempt to triangulate its location via GSM networks or any other network within range. 
     The online platforms may enable users to locate the exact location between their handheld devices, i.e. smart-phones or any other device, from which they are accessing the accompanied online downloaded application, and the luggage tracking device  100 , ensuring enhanced solutions for monitoring the condition and efficiently locating a luggage article. 
       FIG. 3  illustrates the overall operation  200  method for tracking the location and condition of a luggage article  140  that having a luggage-tracking device  100 , according to an exemplary embodiment. 
     In normal operational conditions  210 , data may be received from sensors  111 , i.e. push buttons or any other form, which may then be transferred, recorded and processed in a luggage-tracking device&#39;s  100  GSM module unit  116 . 
     At the same time, in operation  220 , data may be received from operation  210  with additional data possibly being recorded, which may relate to information gathered from, for example, a power source unit  120 , sensors  111  and a transmitter unit  113 . 
     Preferably, this information may be communicated by sending Unstructured Supplementary Services Data (USSD) messages across high priority GSM network channels, or any other method, that may be received by an end point, for example an API or URL. This may reduce power consumption and enhance the reliability of the transmitting capabilities of the luggage lock-tracking device  100 . 
     Information recorded, stored and sent from operation  220  may then be processed, recoded and stored by a server unit  150 , for example a cloud server, as illustrated in operation  230 . This information may then be recoded and configured in a compatible format that may display information gathered from data sources in operation  220  to end users, i.e. travellers, on smart phone applications, or any other form. 
     In addition, operation  230  may also be configured to manage scalability and data transfer to operation  240  in the form of push notifications, which may enable end users to view alerts for when a luggage-tracking device  100  detects condition state changes. 
     With reference to  FIGS. 6 and 7 , in a second embodiment of the present invention, the tracking device  1000  may comprise a self-contained portable device. The portable tracking device  1000  comprises a housing  1002  made from rigid plastics material or other suitably robust material. Advantageously, the portable tracking device  1000  gives a user the option of including the tracking device in any item that requires monitoring. Therefore, the device is not confined for use in a particular item of luggage. 
     The tracking device  1000  houses a processing module  1004  which provides tracking information and enables wireless communication of the information to remote electronic communication devices such as smartphones, computers, networking apparatus and other programmable apparatus. 
     The processing module  1004  comprises a memory  1006 , a memory controller  1008 , one or more processing units (CPUs)  1010 , an accelerometer  1012 , a global positioning satellite (GPS) module  1014 , at least one signal booster  1016 , and radio frequency circuitry  1018  for transmission and receipt of wireless signals. The electronic components communicate over one more communication buses and are powered by a power system which comprises a power source  1020  such as a battery, a power management and recharging system  1022  and any other components associated with the generation, management and distribution of power. The processing module  1004  further comprises an array of light emitting diodes  1024  operable to emit light in response to actuation by a user of the device  1000 . 
     The memory  1006  comprises a non-volatile solid state memory with read/write capabilities. Access to the memory  1006  by other components of the device such as the CPU  1010  and the GPS module  1014  is controlled by the memory controller  1008 . The GPS module  1014  is configured to receive wireless signals from one or more global positioning satellites so that the location of the tracking device  1000  can be determined by the processing module  1004 . Thus, the tracking device  1000  can periodically determine its position and record the location of the device at a particular time in the memory  1006 . 
     The radio frequency circuitry  1018  comprises a radio frequency transceiver and is operable to convert electrical signals into electromagnetic waves and vice versa so that the tracking device  1000  can transmit and receive wireless signals to and from remote communication devices such as handheld devices, other luggage tracking/monitoring communication devices, computers, computer networks or other programmable apparatus. The radio frequency circuitry  1018  is configured to communicate wirelessly using any of a plurality of communication standards, protocols and technologies such as Global System for Mobile Communications (GSM), Bluetooth, Wireless Fidelity (Wi-Fi), ZigBee or any other suitable communication protocol. 
     The signal booster  1016  comprises GPS and GSM booster antennas which enhance the transmission and receipt capabilities of the device. The signal booster  1016  also comprises a signal amplifier operable to amplify an electrical signal for transmission to one or more remote electronic communication devices. Thus, the tracking device  1000  is capable of transmitting and receiving electromagnetic waves in areas of limited reception such as an aircraft cargo or deep building interior. 
     The tracking device  1000  additionally comprises an RFID tag (not shown) operable to receive radio signals from appropriately positioned RFID readers. The RFID tag stores identification information for transmission upon interrogation from an RFID reader. In the event an airport comprises a plurality of RFID readers spaced along a luggage security processing line at known locations, the RFID readers can detect the RFID tag of the device  1000 . Thus, depending on which RFID reader detects the RFID tag of the device, it is possible to determine where the luggage is in the security checking process so that the positional information can be relayed to the smartphone of a user or other remote electronic devices. 
     As with the first embodiment, the accelerometer module  1012  is configured to detect changes in acceleration of the tracking device to determine whether the device  1000  is at rest relative to the surface of the earth or, for example, subject to movement such as along a conveyor belt, during taxiing of an aircraft or during take-off or landing. Using acceleration data communicated from the accelerometer  1012 , the processing module  1004  is operable to disable or enable transmitting capabilities respectively during take-off, taxiing and landing so that the GPS or Bluetooth modules  1018  do not emit wireless signals that could interfere with the functioning of aircraft at crucial times. Data from the accelerometer module  1012  can also be used by the processing module  1004  to determine appropriate times to enter into a sleep mode to conserve power, such as when at rest relative to the surface of the earth. 
     The CPU  1010  runs one or more software programs stored in the memory  1006  to perform functions for the tracking device  1000  and to process data. The software programs comprise a communication module and a position module. The communication module comprises a set of instructions for generating signals for transmission to other electronic communication devices and for handling data received by the RF circuitry  1018 . The position module comprises a set of instructions for processing data received from other electronic communication devices via the communication module, data received from the accelerometer  1012 , and data received from the GPS module  1014 . 
     The position module is operable to determine when the tracking device  1000  should be switched between sleep, airplane and awake states based upon detected movements (or prolonged absence thereof), and also to process positional information data received from the GPS module  1014  and to record the positional information in the memory  1006  along with a time stamp. The position module is also operable to periodically transmit position information to a remote electronic communication device via the communication module. 
     The software programs may also comprise a light module operable to switch the LEDs  1024  between an ‘on’ or ‘off’ state in response to an appropriate user command either via a smartphone or a mechanical switch incorporated into the housing  1002  and electrically coupled to the processing module  1004 . 
     In all other aspects the tracking device according to the second embodiment is substantially the same in function and operation as the first described embodiment. 
     With reference to  FIGS. 8 to 10 , in a further aspect of the present invention, there is shown a locking apparatus  300  which is configured to be incorporated into a piece of luggage to secure the luggage in a closed state. The locking apparatus  300  is configured for use with a tracking device  100 ,  1000  as described above but may also operate in isolation. 
     The locking apparatus  300  comprises a housing  302  made from a rigid plastics material which is substantially cuboidal in shape and which houses a number of components for actuating the locking apparatus  300  and detecting actuation. Whilst plastics or composite material are preferred material for the housing  302  it will be apparent to the skilled person that other suitable materials may be used which have the necessary durability and strength required of a locking apparatus  300  without significantly interfering in the wireless transmission and receipt of signals. 
     The locking apparatus  300  comprises a locking element  304  in the form of a sliding metal locking bar which is seated within the housing  302 . The sliding bar  304  is linearly moveable relative to the housing  302  between a first position in which the locking apparatus  300  is in a locking state (as shown in  FIG. 8 a   ) and a second position in which the locking apparatus  300  is in an unlocked state (as shown in  FIG. 8 b   ). The sliding bar  304  is arranged to move in a direction substantially parallel to the longitudinal axis of the housing  302 . 
     The locking bar  304  comprises two hook shaped projections  306 ,  308  which are fixed relative to the locking bar  304  and which each extend from the locking bar  304  and in a direction along the longitudinal axis of the locking bar  304 , each terminating at a free end. Thus a gap is formed between the two projections  306 ,  308  and the locking bar. The two projections are arranged to cooperate with a pair of apertures  312 ,  314  formed in the housing  302  of the locking apparatus  300 . Each projection  306 ,  308  is therefore associated with a corresponding aperture  312 ,  314 . The spacing between the two projections  306 ,  308  is approximately equal to the spacing between the two apertures  312 ,  314 . The two projections  306 ,  308  are arranged on the locking bar  304  such that when the locking bar  304  is in the first position, each projection  306 ,  308  is substantially aligned with a corresponding aperture  312 ,  314 . The two projections  306 ,  308  are sized and shaped such that when the locking bar  304  is in the first position (as shown in  FIG. 8 a   ), the two projections  306 ,  308  extend substantially across their corresponding apertures  312 ,  314 . Furthermore, the two projections  306 ,  308  are sized and shaped such that when the locking bar  304  is in the second position (as shown in  FIG. 8 b   ), the two projections  306 ,  308  do not extend across their respective corresponding apertures. Thus, in the second position, a space  316  is formed between the free end of each projection  306 ,  308  and a side of the corresponding aperture  312 ,  314 . 
     The two apertures  312 ,  314  are each shaped to receive a portion of a pull tab of a zipper (not shown). Thus, when the locking bar  304  is in the second position, a pull tab can be inserted into the space  316  between the free end of a projection  306 ,  308  and a side of the corresponding aperture  312 ,  314 . The projections  306 ,  308  are each shaped such that they can extend through an aperture or eye formed in an end of the pull tab. Therefore, a pull tab can be arranged in the space  316  and the eye of the pull tab can be oriented so that the projection  306 ,  308  extends through the eye of the pull tab when the locking bar  304  and, hence, the projection  306 ,  308  moves from the second position to the first position. In this locking state, the projection  306 ,  308  extends through the eye of the pull tab across the aperture  312 ,  314  of the housing  302  to prevent the pull tab from being removed from the housing aperture  312 ,  314  in which the pull tab is seated. 
     The side of each projection  306 ,  308  that faces outwardly from the two housing apertures  312 ,  314  is tapered so that when part of the pull tab is inserted into an aperture  312 ,  314 , the corresponding projection is urged in a direction away from the housing aperture  312 ,  314  so that the space  316  is formed between the free end of the projection  306 ,  308  and a side of the housing aperture  312 ,  314 . The locking bar  304  is biased toward the locking state position by springs (not shown) so that the locking bar  304  is urged from the second position to the first position. Thus, when a pull tab is inserted into a housing aperture  312 ,  314  to urge the projection  306 ,  308  toward the second position and when the pull tab eye is oriented to be aligned with the free end of the projection  306 ,  308 , the projection  306 ,  308  is urged back through the pull tab eye from the second position to the first position due to biasing of the locking bar  304 . 
     The locking bar  304  is associated with a first locking mechanism  316  and a second locking mechanism  318 . The first locking mechanism comprises a key lock  316 . In the embodiment depicted, the key lock  316  is a master keyed pin tumbler lock which comprises a cylinder lock for the receipt of a master key. The master keyed pin tumbler lock is configured for actuation in accordance with Transport Security Administration (TSA) requirements and thus is operable with a TSA master key. The first locking mechanism  316  is operable between two states; a first state in which the locking mechanism  316  interacts with and prevents movement of the locking bar  304  relative to the housing  302  and a second state in which the locking mechanism  316  permits movement of the locking bar  304  relative to the housing  302 . 
     With reference to  FIG. 9 , the key lock  316  is linked to the locking bar  304  by a curved linking member  317  which is linearly movable along a plane parallel to the plane of movement of the locking bar  304 . The linking member  317  is connected to the key lock  316  by an arm  316   a  such that actuation of the key lock  316  from a locked position to an unlocked position causes the arm  316   a  to rotate which, in turn, causes the linking member  317  to rotate with the arm  316   a  in a direction away from the locking bar  304 . Due to the curvature of the interfacing parts of the linking member  317  and the locking bar  304 , when the linking member  317  is rotated relative to the locking bar  304 , the locking bar  304  can be moved from the locked position to the unlocked position against a biasing force acting on the locking bar  304 . 
     The second locking mechanism  318  comprises a number combination lock. The number combination lock comprises three rotatable discs  318   a,    318   b,    318   c  each having numbering from 0 to 9 printed around their respective circumferences. The combination lock  318  further comprises a locking pin  319  which extends through the rotatable discs. The locking pin  319  comprises two parts, a first tube part  319   a  which is fixed relative to the combination lock  318  and a second cylindrical part  319   b  which is received into the tube part  319   a.  The second part  319   b  is linearly movable within the first part  319   a  between two positions along a plane parallel to the plane of movement of the linking member  317  and the locking bar  304 . The locking pin  319  has a head portion  319   c  which interfaces with the linking member  317 . 
     The combination lock  318  is operable between a locking state and an unlocking state. In the locking state, the combination lock  318  restricts movement of the second part  319   b  relative to the first part  319   a  of the pin  319  such that the locking bar  304  in combination with the linking member  317  cannot be moved to the unlocked position. In the unlocking state, which is achieved by arranging each of the discs  318  in a correct orientation according to a predetermined number combination, the combination lock  318  permits movement of the locking second part  319   b  relative to the first part  319   a  of the pin  319 . When the second part  319   b  of the pin  319  is movable relative to the first part  319   a,  movement of the locking bar  304  in a direction away from the key cylinder  316  to an unlocked position also moves the linking member  317  and cylinder arm  316   a  toward the locking pin head  319   c  and, hence, the unlocked position. Thus, the locking apparatus can be unlocked even without actuation of the key cylinder and vice versa. 
     To facilitate movement of the locking bar from a locked position to an unlocked position, the locking bar  304  is attached to a button (not shown) which extends outside the housing and which is operable by a user. When the combination lock  318  or the key cylinder  316  is in an unlocking state, the button and hence the locking bar  304  is slidable relative to the housing in a direction away from the key cylinder  316  to the unlocked position. 
     The locking apparatus  300  further comprises electronic components  320  which are configured to detect operation of the first locking mechanism  316  and the locking bar  304  and to communicate operational information to remote devices such as a tracking device  100 ,  1000  described above. The electronic components comprise a memory  322 , a memory controller  324 , one or more central processing units (CPUs)  326 , an accelerometer  328 , a rotational position sensor  330 , a linear position sensor  332 , and radio frequency circuitry  334 . In the embodiment depicted, the radio frequency circuitry  334  is configured to communicate wirelessly using any of a plurality of communication standards, protocols and technologies such as Global System for Mobile Communications (GSM), Bluetooth, Wireless Fidelity (Wi-Fi), ZigBee or any other suitable communication protocol. It will be appreciated that more than one communication module may be incorporated into the locking apparatus to increase the number of communication protocols via which the apparatus can communicate wirelessly. 
     The electronic components communicate over one more communication buses and are powered by a power system. The power system comprises a power source  336  such as a button battery, a power management system  338  and any other components associated with the generation, management and distribution of power to the various electronic components of the locking apparatus  300 . The housing  302  comprises a removable portion (not shown) which is releasably attached to the rest of the housing  302  and which allows a user to gain access to the housing interior and, in particular, the region of the housing in which the battery  336  is situated so that the battery  336  can be replaced when it runs flat. The removable portion is arranged on a part of the housing  302  such that when the locking apparatus  300  is incorporated into a luggage the removable portion is exposed to the luggage interior. Thus, access to the battery compartment of the housing  302  via the removable portion can only be gained when the luggage is in an open state. 
     The rotational position sensor  330  comprises a potentiometer. In a preferred implementation, the potentiometer comprises a conductive or resistive track, having two end terminals, which at least partially surrounds the cylinder lock. The track is connected at its end terminals to apply a DC reference voltage across the track. A wiper is attached to and is fixed relative to the cylinder lock such that the wiper rotates as the cylinder lock rotates. The free end of the wiper remote from the cylinder lock contacts the track such that as the cylinder lock rotates, the wiper travels along the track, thus changing the position of contact of the wiper with the track. The wiper also comprises a terminal from which an output voltage signal may be read and processed by the CPU  326 . When the wiper changes position along the track due to rotation of the cylinder lock, the output voltage of the wiper increases in proportion to distance from the positive terminal of the track. Thus, it is possible to determine the extent to which the cylinder lock has rotated and whether or not it has been moved to an open position. 
     Since actuation of the cylinder lock  316  by a key is usually a relatively fast, smooth procedure and since attempted tampering of the lock using, for example, a hairpin is usually a relatively erratic movement over a longer period of time, the processor is configured to distinguish between a key actuated event and a tampering event based upon detected movement patterns of the cylinder lock or physical force on the tactile sensor (as the case may be). 
     The rotational position sensor  330  is operable to transmit a signal relating to a detection of rotation by a key to the CPU  326  for processing and storing in the memory  322 . A detected key interaction event is stored in memory  322  along with a time stamp to indicate when the physical event occurred and, thus, record when a key was inserted into the key cylinder  316 . When the locking apparatus  300  is used in conjunction with a tracking device  100 ,  1000 , a recorded interaction event can also be associated with the coordinates of a specific location at the moment the event is recorded as determined by the GPS module  1014  of the tracking device  100 ,  1000 . 
     Other types of sensors in various arrangements may be used for monitoring the cylinder lock  316  as will be apparent to a person skilled in the art. For example, as an alternative or addition to the rotational position sensor  330 , a tactile sensor may be arranged inside the housing  302  at the end of the cylinder lock  316  remote from the cylinder lock key opening. The tactile sensor can be configured to detect a mechanical force being applied to the sensor. The tactile sensor can be arranged relative to the cylinder lock  316  such that, when a key is inserted into the cylinder lock  316 , the end of the key imparts a mechanical force onto the sensor. Thus, the sensor can detect when a key has been fully inserted into the cylinder lock  316 . 
     The linear position sensor  332  is associated with the locking bar  304  and is operable to detect linear movement of the locking bar  304  relative to the housing  302 . In the embodiment depicted, the linear position sensor  332  comprises a straight conductive or resistive track having two terminal ends. A wiper having its own terminal is fixed relative to the locking bar  304  and arranged in sliding contact with the straight track. Together, the track and terminal form a potential divider operable to detect a change in voltage as the position of the wiper and, hence, the locking bar  304  moves relative to the track. The linear position sensor  332  is electrically coupled to a current transformer  334  which is used to configure data recorded from the linear position sensor  332  and forward the data to the CPU  326  for processing. 
     By tracking movement of the locking bar  304  it is possible to determine by process of elimination whether or not the combination lock  318  has been activated. In the event the cylinder lock  316  is not detected by the sensors as having been actuated but the locking bar  304  is detected as having moved from a locking state to an unlocking state, the CPU  326  is able to determine that the combination lock  318  has been activated. 
     It will be apparent to a person skilled in the art that in addition to monitoring the locking bar  304  or as an alternative to monitoring the locking bar  304 , one or more sensors could be associated with the second locking mechanism  318 , in this case the combination lock  318 , to directly monitor actuation of the second locking mechanism  318 . A suitable sensor is a rotational sensor  333  as described above comprising a resistive track having end terminals and a wiper having its own terminal and fixed to the axle and movable with the disc relative to the track. The resulting combination forms a potentiometer for monitoring rotation of one or more combination locks through measuring the changing voltage as the wiper moves with the combination disc relative to the track. 
     In addition to the rotational sensor  333  for detecting rotation of one or more combination discs, a pressure sensor  335  may be arranged relative to the combination locking pin  319  to measure the absence or presence of a force applied to the sensor by the locking pin head  319   c.  In this arrangement, linear movement of the combination pin head  319   c  away from or toward the pressure sensor  335  is detected by the pressure sensor  335 . The output from the pressure sensor  335  may be used by the CPU  326  to determine whether the locking pin  319  is moving from a locking position to an unlocking position or vice versa. As above, since the movement pattern of the locking pin  319  is likely to be relatively smooth and continuous when genuinely unlocked and relatively erratic for a tampering event, the CPU is configured to distinguish between the two types of event depending on the detected movement pattern of the locking pin  319 . 
     The CPU  326  runs one or more software programs stored in the memory  322  to perform functions for the locking apparatus  300  and to process data. The software programs comprise a communication module and a status module. The communication module comprises a set of instructions for generating signals for transmission to other electronic communication devices and for handling data received by the RF circuitry  334 . The status module comprises a set of instructions for processing data received from other electronic communication devices via the communication module, data received from the accelerometer  328 , and data received from the rotation sensors  330 ,  333 , pressure sensor  335  and linear position sensor  332 . The status module is operable to determine when the locking apparatus  300  should be switched between sleep and awake states, and also to determine when an unlocking event is detected and to record the unlocking event in the memory  322  along with a time stamp. The status module is also operable to transmit status information to a remote electronic communication device via the communication module. 
     The software programs further comprise a passenger information module which comprises a set of instructions for storing and transmitting data relating to a user of the apparatus and the intended movements of the passenger. For example, the data may comprise a passenger&#39;s travel itinerary, passenger identification information, and information relating to the departure location and arrival location such as a specified airport terminal, transportation network locations (taxi ranks, bus stops and train stations) and baggage collection areas. The passenger information module is operable to transmit useful quick reference information to a remote device such as a passenger&#39;s smartphone to enable the passenger to have quick access to required information. 
     It will be appreciated by a person skilled in the art that different combinations of locking mechanisms and sensors may be implemented. For example, for a locking apparatus comprising only a single locking mechanism such as a key cylinder, a single sensor may be used to monitor the locking mechanism or the locking bar. Alternatively, two sensors may be used, a first sensor to monitor the locking mechanism and a second sensor to monitor the locking element. 
     In use, the locking apparatus  300  is incorporated into the body of an item of luggage such that the longitudinal axis of the housing  302  is substantially aligned with a straight section of zipper track of the luggage. Therefore, the locking bar  304  and, hence, the two projections  306 ,  308  are linearly moveable in a direction substantially parallel to the zipper track. Thus, where the zipper comprises two zipper sliders with corresponding pull tabs, the two pull tabs may be arranged to extend from the zipper track into the two apertures  312 ,  314  of the housing  302  for engagement with the two projections  306 ,  308  as described above. 
     It will be appreciated by the person skilled in the art that the locking apparatus may comprise a standalone self-contained device such as a padlock that can be used with the luggage to secure the luggage. 
     The locking apparatus  300  is operable to communicate with a remote electronic communication device such as a smartphone via the RF circuitry  334 . The smartphone may comprise a software application stored in memory which is operable to communicate with the locking apparatus via the smartphone and obtain status information from the locking apparatus  300 . 
     When in an awake state, the locking apparatus  300  is configured to periodically transmit status information via Bluetooth to the smartphone. If no Bluetooth enabled device is within range of the locking apparatus  300 , the locking apparatus  300  stores status information and recorded events for later transmission when a Bluetooth enabled device such as a smartphone comes within range. The status information comprises the last recorded locking status i.e. “locked” or “unlocked” as detected by the sensors  330 ,  332 ,  333  and  335 , and details of any previous unlocking events as detected by the sensors. An unlocking event is detected by the rotational position sensor  330  when the sensor is detects rotation of the key cylinder  316 . An unlocking event is also detected by the linear position sensor  332  and/or the pressure sensor  335  when movement of the locking bar  304  and second pin part  319   b  relative to the first pin part  319   a  occurs. 
     In addition, owing to the sensitivity of the position sensor  332  and the pressure sensor  335 , the locking apparatus  300  is operable to detect smaller movements in the locking bar  304  which may not exceed the threshold to trigger an unlocking event but which may be sufficient to indicate a tampering event. The status information may therefore include details of tampering events. Each recorded event is associated with a time stamp to indicate when the event took place. Furthermore, each recorded event is associated with a particular sensor  330 ,  332 ,  333 ,  335 , to distinguish between an unlocking event actuated by the key cylinder  316  and an unlocking or tampering event actuated by the combination lock  318 . Thus, the locking apparatus  300  is capable of determining whether the locking apparatus  300  is unlocked via the key cylinder part  316 , perhaps using a TSA master key, or by the combination lock  318  by an unauthorised third party. 
     The software application also permits a user to query the locking apparatus  300  to determine status information. For example, if a user wishes to determine the locking status of an item of luggage, the user may instruct the software application to transmit a query message from the smartphone either directly to the locking apparatus over Bluetooth frequencies or via a GSM network, where available. The transceiver of the locking apparatus receives the message for processing by the processing module and transmits a response message with status information. In addition, the processing module is configured to transmit status information to the user immediately upon detection of an unlocking or tampering event so that the user is alerted to the event and can act accordingly. 
     When the locking bar  304  is in the first position, the locking apparatus  300  assumes that it is in a locked state as the two projections  306 ,  308  extend across the apparatus in a locking configuration. However, in the first position, since the pull tabs of a pair of zippers may not necessarily be seated in the two apertures  312 ,  314  and retained in place by the two projections  306 ,  308  and since the combination lock  318  or the key lock  316  may be in an open position thereby permitting the locking bar  304  to be moved to the unlocked position, the software application on a smartphone comprises means for calibrating the locking apparatus  300  to specify if the locking apparatus  300  is in a locked or unlocked state. It is therefore the user&#39;s responsibility to ensure the pull tabs are secured in place and the locking apparatus  300  is set to a locked configuration and to use the software application to specify that the locking apparatus is ‘locked’. Thus, after the user has parted with the luggage and until the user is reunited with the luggage, any event detected by the sensors  330 ,  332 ,  333 ,  335  of the locking apparatus  300  may be recorded as an unlocking event or a tampering event and transmitted or stored for later transmission to the smartphone accordingly. 
     The status module is operable to process data from the accelerometer  328  to switch the locking apparatus into a “sleep” state when no relative movement is detected or an “airplane” mode when an acceleration profile is detected which corresponds to the acceleration profile of an aircraft during take-off, both for safety purposes and for power saving. The status module is also operable to switch the locking apparatus to an “awake” state when relative movement is detected or when a deceleration profile is detected which corresponds to a deceleration profile of an aircraft during landing. The processing module may comprise a timer to delay switching between the sleep, airplane and awake states when relative movement, or absence thereof, or an acceleration or deceleration profile is detected. 
     The locking apparatus  300  may form part of a wider system  400  for monitoring and tracking luggage. With reference to  FIG. 11 , the system  400  may comprise a locking apparatus  300  as described above, a remote computer server  410  comprising a software management program and one or more smartphones  420  comprising a software application configured to communicate with the devices of the system. Each component of the system may work together to provide reliable status information. 
     The management platform may form a centralised processing unit for processing data from a plurality of electronic communication devices such as smartphones, tracking devices and locking apparatus. Thus, where there are a plurality of users of the tracking and monitoring system, each user may register an individual account with the management platform and associate their respective tracking devices and locking apparatus with their account. The management platform therefore maintains a centralised unit storing status and positional information to be interrogated by a plurality of different users to determine the status of their respective luggage via an electronic communication device comprising appropriate software. 
     With reference to  FIG. 12 , in a wider system additionally comprising a tracking device  100 ,  1000 , the tracking device  100 ,  1000  and the locking apparatus  300  may be operable to communicate directly with a smartphone  520  via Bluetooth or over a GSM network. The tracking device  100 ,  1000  and the locking apparatus  300  are also operable to communicate with one another to share status and positional information. For example, the locking apparatus  300  may transmit a request to the tracking device  100 ,  1000  for positional information when an unlocking or tampering event is detected so that the positional information can be recorded in the locking apparatus memory by the status module along with a time stamp and the type of event detected e.g. unlocking event by TSA lock, unlocking event by combination lock or tampering event by combination lock. 
     Furthermore, the tracking device  100 ,  1000  may perform the function of an intermediate node for the locking apparatus  300  to permit signals to be relayed from the locking apparatus  300  to a smartphone  520  or server  510  via the tracking device  100 ,  1000  when the locking apparatus  300  is out of range of a Bluetooth enabled smartphone or other electronic communication device. Likewise, where the locking apparatus  300  has an available wireless connection and the tracking device does not, the locking apparatus may relay messages to the server  510  or smartphone  520  from the tracking device  100 ,  1000 . The wider system  500  may additionally comprise one or more RFID readers  530  for transmitting positional information to the tracking device based upon received identification information from passing RFID tags of a tracking device or locking apparatus. Additionally or alternatively to RFID readers, the wider system  500  may comprise a cloud beacon having Bluetooth and Wi-Fi connectivity for communicating with the locking apparatus  300  and tracking device  100 ,  1000 . 
     Various exemplary embodiments of the present invention will serve to provide end users, i.e. travellers, will an automated system that allows enhanced and reliable visibility surrounding the location and general condition of luggage articles. 
     By using a combination of transmitting capabilities and sensory technology, travellers will be able to not only track physical location of their luggage, but also monitor whether their luggage has been opened by TSA official, opened by the correct combination, any attempts to access the contents of their luggage have been made by unauthorised persons, whether their luggage is airborne, i.e. airplane mode, or been safely stored away in a closet of their choosing, for example the device may indicate offline mode. 
     The present invention has been designed, from a user perspective, to provide an automated system that demands minimal involvement from end users. The tracking device can automatically determine when to transmit or not transmit, knowing when to alert travellers of information that is deemed important to the defined user and inform the user when the tracking device will need to be recharged. 
     Moreover, the present invention provides all functionality at minimal cost, without data roaming charges, and with high priority transmitting channels, i.e. USSD messaging over GSM networks, ensuring that users can reliably locate and monitor the condition of their luggage even when a luggage article is in the most remote locations. This method of transmitting requires reduced levels of power usage when compared to other transmission forms, enabling the device to retain electrical power for prolonged periods of time.
