Detailed Description of the Drawings

Figure 1 shows a schematic diagram of a locking device 10 provided in accordance with embodiments. The locking device 10 is fixedly mountable to an object and is provided to secure the object to another part of the object and/or to a further object. In the present embodiment, the locking device 10 is fixedly mountable to a frame of a bicycle 12.

The locking device 10 has a housing 14 mounted to the bicycle 12. The locking device has a retractable cable system 16 that has a retractable cable 18, extendable from the retractable cable system 16. For brevity, the retractable cable 18 may be referred to as a cable. The locking device also has an engagement mechanism 20 and a locking mechanism 22.

The locking device 10 also has a processing circuitry module 24 that includes tamper detection circuitry 26, communication circuitry 28 and location circuitry 30. Processing circuitry module 24 may also be referred to as processing circuitry or a processing resource.

The locking device 10 also has a sensor module 32 which has one or more sensors. The locking device also has an alarm module 34 and a user input device 36. In the present embodiment, the locking device 10 has an attachment mechanism 38 for fixedly attaching the housing 14 of the locking device 10 to the bicycle 12. The housing 14 may also be referred to as casing.

Although shown in Figure 1 as part of the same circuitry 24, it will be understood that tamper detection circuitry 26, communication circuitry 28 and location circuitry 30 can be provided separately. The communication circuitry 28 and location circuitry 30 form part of one or more security devices provided as part of the locking device 10.

As described in further detail in the following, the locking device 10 provided in accordance with embodiments, is operable to secure the bicycle 12 to a further object, for example, by extending the retractable cable 16 and looping the retractable cable 16 around the further object before engaging the retractable cable 16 with the engagement mechanism 20 to form a closed loop about the further object. On engagement the free end of the retractable cable 16 is locked to the housing 14. The locking device 10 is also configured to be activated via interaction between a user and the user input device 36. When activated, the locking device 10 monitors sensor output from the sensor module 32 for output indicative of tampering activity with the locking device. One of the sensors of sensor module 32 is a sensor wire that runs through the length of the cable 18. The sensor wire allows tampering activity with the cable 18 to be detected. The locking device 10 proceeds to perform a series of security actions, for example, activation of an alarm of alarm module 34, in response to detecting tampering activity.

The engagement mechanism 20 is configured to engage the free end of the retractable cable, thereby to place the retractable cable into an engaged position. In some embodiments, the at least one locking mechanism is mechanically coupled to the engagement mechanism to lock and unlock the cable in the engaged position. In some embodiments, a further locking mechanism is provided to lock the cable into the engaged position.

Figure 2 shows a perspective view of the locking device 10, in accordance with embodiments. Figure 2 is provided to illustrate further structural elements of the locking device 10 that are not clearly shown in Figure 1. As shown in Figure 2, the locking device 10 has a power source 42 and a door 44 provided as part of the outer surface of the housing 14. The door 44 is provided on a hinge 45. In the present embodiment, the hinge 45 is a secure and tamper-proof piano hinge. The door 44 is openable and lockable, as described below. The door 44, when opened, provides access to the interior of the housing 14, and the components that are contained inside the housing 14.

Figure 2 also shows an audio alarm 46 and light source 48 provided inside the housing 14 as part of the alarm module 34. Figure 2 also shows part of the retractable cable system 16, in particular, the storage drum 50 and the retractable cable 18. A GPS unit 52 and SIM card 54 are shown in Figure 2 as representative of the location circuitry 30 and communication circuitry 28, respectively.

As shown in Figure 2, the door 44 is closeable such that, when closed, no exposed edge is shown. The door 44, when closed, provides a water and moisture resistant seal to the interior of the housing 14.

The power source 42 can be any suitable power source. In the present embodiment, a battery receiver for receiving a battery is provided inside housing 14. The power source 42 can be a rechargeable or a non-rechargeable power source. The power source 42 can be a removable power source. For embodiments with re-chargeable batteries, an electronic charging port is provided on the outer housing 14 for receiving an external power supply for charging the power source 42. In other embodiments, the external power supply is provided through the door 44. The power source 42 is connected to the electronic components of the locking device 10. In some embodiments, as described in further detail below, further power source(s) are provided as back-up power sources. For example, a further power source (not shown) is provided for the communication circuitry 28 and/or the location circuitry 30 for sending emergency alerts.

As shown in Figure 2, the retractable cable system 16 has a storage drum 50 for storing the retractable cable 18. At least part or substantially all of the retractable cable 18 can be stored on the storage drum 50. The retractable cable 18 is configured to be extended from the retractable cable system 16. In particular, the retractable cable 18 is configured to be unwound from the storage drum 50, and extended from the housing 14. When the retractable cable 18 is extended from the storage drum 50, only part of the cable will be stored on the storage drum 50.

The retractable cable 18 has a first end and a second end. In the present embodiment, the first end is provided outside the housing 14. The retractable cable 18 exits the housing 14 through an exit aperture provided in the outer surface of the housing 14. The first end has a first connector 56. In the present embodiment, the second end of the retractable cable 18 is contained inside the housing 14. The second end of the cable is inside the housing 14 and has a stable, non-moveable connection internal to the housing. As described in further detail below, the second end of cable provides an electronic connection with the electronic components of the locking device 10.

The retractable cable 18 is configured to be extended from the retractable cable system 16 to be in one or more extended configurations. Figure 1 shows, schematically, the retractable cable 18 in an extended configuration. The dashed line shows one example path the retractable cable 18 can be extended through to extend to the engagement mechanism 20.

The retractable cable system 16 is configured to apply a tension or force to the extended cable to rewind or draw in the extended cable onto the storage drum.

In the present embodiment, the retractable cable system 16 is a recoil spring retractor. The retractable cable 18 is a strengthened cable. The retractable cable system 16 is configured to automatically apply a tension to the extended cable thereby to rewind at least part of the cable onto the storage drum. The recoil spring strength is selected to allow the cable to be extended without undue effort or excessive force/strength of an individual using the product.

When in an extended configuration, the retractable cable 18 comprises a free portion outside the housing 14 and a contained portion inside the housing 14. The free portion can be considered as the portion of cable between the exit aperture and the first end of the cable. The free portion is moveable relative to the housing 14. The length of the free portion can be increased by pulling on the cable to draw the cable from the storage drum. Increasing the length of the free portion will cause a decrease in the length of the contained portion.

When in an un-extended configuration, also referred to as a rest configuration, a large proportion of the contained portion of the cable 18 is wound around the storage drum 50. A sub-portion of the contained portion inside the housing 14 extends between the storage drum 50 and the exit aperture provided in the outer surface of the housing 14. The first end of the cable 18 is prevented from entering the housing by the connector 56 which is larger than the size of the exit aperture. In the rest configuration, the sub-portion of cable 18 extending between storage drum 50 and exit aperture is held fixed between the storage drum 50 and the outer surface, such that part of the cable is accessible outside the housing 14, to be pulled by a user.

As described above, the locking device 10 has an engagement mechanism 20. In the present embodiment, part of the engagement mechanism 20 is provided at an outer surface of the housing 14. Figure 2 shows a second connector 58 provided as part of the engagement mechanism 20. The second connector 58 is configured to engage with the first connector 56 of the first end of the cable 18. When engaged at the second connector 58, the retractable cable 18 and part of the housing 14 form at least part of a closed loop. The formed closed loop is continuous. The retractable cable system 16 is configured to apply a tension to the closed loop thereby to tighten the closed loop, for example, around a further object.

In some embodiments, the second connector 58 provides an aperture for receiving the free end of the retractable cable.

In some embodiments, the second end of the retractable cable is provided at the other side of the second connector 58 such that, when connected, the retractable cable 18 itself forms a complete closed loop, such that part of the closed loop is provided outside the housing 14 and part of the closed loop is provided inside the housing 14.

The first connector 56 is configured to form a connection with the second connector 58. The second connector 58 is a female connector port provided at the outer surface of the housing 14 and the first connector 56 is a male connector plug. The second connector 58 thus includes an aperture for receiving the first connector 56. The male connector plug is configured to be received and engaged by the female connector port.

A male connector recess (not shown) is also provided on the outer surface of the housing 14 which is sized such that the male connector plug of the retractable cable 18 sits at rest in the outer surface of the housing 14. The retractable cable 18 is configured to be pulled, by gripping the connector plug, to an extended configuration. The connector plug is grippable by a user. In some embodiments, a handle or grip is provided on the connector plug to facilitate pulling.

In some embodiments, the engagement mechanism comprises further engagement features. Cable engagement features are provided on the cable and have corresponding housing engagement features provided as part of the housing. For example, a groove may be provided on the surface of the first connector 56 of the cable 18 and a corresponding engaging member is provided in second connector 58, for example, inside the aperture for receiving the first connector. In use, the connector 56 is received in the recess and the engaging member mechanically couples with the groove, thereby securing the first connector 56 with the second connector 58.

It will be understood that more than one engagement feature can be provided, in accordance with embodiments, and the other suitable engagement feature pairs can be used. For example, a latch or other suitable fastening means can be used.

The user input device 36 is electronically connected to the locking mechanism 22 and processing circuitry 24. The user input device 36 has associated circuitry that can process received user input data and transmit control signals to the processing circuitry 24. The associated circuitry may be provided as part of the user input device 36 or as part of processing circuitry 24. The associated circuitry is configured to verify user input data.

In the present embodiment, the user input device 36 is a key pad device 60, as shown in Figure 2. The key pad device 60 has a nine digit keypad which is configured to receive user input data, in the form of a pre-determined code. The key pad has associated circuitry configured to process the received user input data and verify that the code entered by a user matches a pre-determined code. On successful verification, the key pad device 60 sends a signal to the processing circuitry 22 indicative that the user input data has been input correctly and the processing circuitry 22 will then take corresponding action including performing a locking and/or unlocking and/or an activation process and/or deactivation process.

In other embodiments, the user input device 36 is a wireless signal receiver configured to receive wireless signal data representative of a code. The wireless signal is sent from a corresponding wireless signal transmitter. In some embodiments, the wireless signal transmitter is provided as a key fob that can be packaged together with the locking device 10. In other embodiments, the wireless signal transmitter is a remote computer device, for example, a mobile device, with a processor and transmitter configured to send said signal. In such embodiments, it will be understood that the user input device 36 can be a separate signal receiver or can use at least part of the communication circuitry 28.

The locking device 10 may further comprise a user input device 36 configured to receive user input data and associated circuitry for processing said user input data thereby to verify the user input data such that, on successful verification, the associated circuitry is configured to perform a locking and/or unlocking process using the at least one locking mechanism 22.

In some embodiments, the pre-determined code can be set or changed by performing a key configuration process with the processing circuitry and/or the signal transmitter.

In some embodiments, one or more visual indicators are provided to indicate that the locking device 10 is armed and/or ready to be armed and/or not armed. In the present embodiment, visual indication is provided, in part, by a back-light of the key pad 60. The key pad lights up when the cable is engaged and ready to receive the user input. A further light is provided that turns on to indicate that the locking device 10 is now active.

In some embodiments, a visual indication can be provided by light 48.

In the above described embodiment, the tamper detection circuitry 26 monitors output from one or more sensors of the sensor module 32. In the following, different types of sensor suitable for the locking device 10 are described. It will be understood that some embodiments of the locking device 10 can have one or more sensors of the following different types of sensor.

A first sensor, a sensor wire, is provided as part of the retractable cable 18, and will be described in further detail below.

A second sensor is provided at the outer surface of the housing 14, for example, at door 44 to provide sensor output representative of a forced or unauthorized attempt to open the door 44. The second sensor can be one of a pressure, force or a light sensor or combination thereof.

A third sensor is provided at the engagement mechanism to provide sensor output representative of an unauthorized or forced attempt at removing the cable, when engaged. As described above for the second sensor, the third sensor can be one of a pressure, force or light sensor or combination thereof.

A fourth sensor is provided at the locking mechanism 22 to provide sensor output representative of an unauthorised or forced attempt at unlocking the locking device 10. As described above for the second sensor, the third sensor can be one of a pressure, force or light sensor or combination thereof A fifth sensor is provided at a surface of the housing to provide sensor output representative of tampering with the locking device housing by penetration or introduction of fluids. As described above for the second sensor, the third sensor can be one of a pressure, force, light sensor, moisture sensor or combination thereof In further embodiments, further sensors can be provided as part of the housing 14 to detect forced or unauthorised attempt at opening, removing or tampering with the housing 14.

It will be understood that any suitable sensors can be provided. As a non-limiting example, commercially available sensors can be used in the locking device.

As described above, in the present embodiment, the locking device 10 has a sensor that is provided as part of the retractable cable. A sensor wire (not shown) forms an inner core of the retractable cable 18. The sensor wire is electronically coupled to the tamper detection circuitry 26.

The tamper detection circuitry 26 is configured to input one or more input signals to the sensor wire and also to perform monitoring processes on the output signals from the sensor wire. By processing the output signals, the tamper detection circuitry 26 can determine one or more properties of said output signals that may be representative of tampering activity with one or more of the cable 18, the housing 14 and/or the engagement mechanism 20.

In the present embodiment, the sensor wire forms part of an electronic security circuit.

The security circuit can be closed by engaging the cable with the engagement mechanism 20. A closed circuit is therefore formed when the retractable cable 18 is engaged. In the present embodiment, the tamper detection circuitry 26 is configured to provide an electric current through the sensor wire when the retractable cable 18 is engaged and when the security circuit is closed. In the present embodiment, the current is provided through the sensor wire in response to a successful activation of the device, for example, following a successful verification of user input data to user input device 36. The tamper detection circuitry 26 is configured to monitor one or more properties of the electric current in the sensor wire thereby to determine if tampering activity is taking place.

In the present embodiment, the engagement mechanism 20 provides both a mechanical connection and an electrical connection thus allowing the security circuit to be closed. In particular, the engagement mechanism 20 provides an electronic connection between the sensor wire and the circuitry inside the housing. The first connector 56 and the second connector 58 thus contain conductive elements that provide an electrical connection through the outer surface of the housing 14. In some embodiments, a closed loop is provided through the entire retractable cable, when the engagement mechanism, at a surface of the housing, is configured to receive, on a first side the free end of the retractable cable, and at a second side, the fixed end of the

retractable cable.

As a non-limiting example, by monitoring for a change in electric current in the sensor wire, tampering activity in the retractable cable may be detected. For example, a drop in measured electric current may correspond to the security circuit being opened which may correspond to a breakage of the retractable cable 18.

In some further embodiments, the sensor wire is actually two or more inner wires running through the length of the retractable cable 18. In a further embodiment, the retractable cable 18 has a core of a positive and negative low power electrical connection wires and insulation that acts to electronically insulate the wires from each other. In this embodiment, when the retractable cable 18 is engaged the two wires form part of the completed security circuit. By providing two sensor wires, a more reliable sensor may be provided.

The one or more sensor wires are insulated by an insulating layer, for example, a plastic sheath or similar material. A further armour layer is provided around the insulating layer. The armour layer comprises armoured wire sheathing that also has an outer layer of plastic or similar material. In the present embodiment, the overall cable diameter is about 3mm. The cable may be robust against accidental damage by scuffing and chafing over a period of time.

Turning now to the locking mechanism 22, as has been described above, the locking mechanism 22 is provided to prevent the retractable cable 18, when engaged, from being removed from the engagement mechanism 22. In the present embodiment, the locking mechanism 22 also prevents the door 44 from being opened.

In the present embodiment, the locking mechanism corresponds to a first locking mechanism 62 and a second locking mechanism 64, as shown in Figure 2. The first locking mechanism 62 is a physical lock mechanism that is operable using a physical key and the second locking mechanism 64 is a magnetic lock controllable by electronic control signals from the processing circuitry 24. The magnetic lock can be turned on, in response to, for example, verification of user input data.

A user is able to secure the locking device by performing a two-stage locking process including: a first locking process using the mechanical lock 62 and a second locking process by providing user input to the user input device 36. By providing two locking mechanisms as part of locking mechanism 22, the locking device 10 may be made more secure.

The mechanical lock is provided to lock the door. In some embodiments, the mechanical lock is coupled to the cable engagement mechanism such that, by locking the mechanical lock, the cable is locked in its engaged configuration and the cable cannot be disengaged without unlocking the mechanical lock.

The second lock is an electro-magnetic lock that provides security for the housing and the circuitry.

In embodiments where the first mechanical lock does not lock the free end of the mechanical cable into place, a further separate locking mechanism is provided to lock the free end of the mechanical cable into secure locked in position. The further lock can be a physical lock or an electromagnetic lock. The further lock may be operable when the system is activated. In such embodiments, electro-magnetic lock provides security for the housing and components inside the housing, including the circuitry and one or more alarms.

In the present embodiment, the locking mechanism is configured to lock the cable automatically in response to the cable being engaged. In the present embodiment, the physical locking mechanism 62 is configured to lock in response to the cable 18 being engaged. The physical locking mechanism 62 can be unlocked by using a key.

The magnetic lock is provided on the door 44 of the housing 14 and, when locked, prevents the door being opened. In some embodiments, the magnetic lock has a failsafe mode that prevents access to the device even when the battery runs out. The failsafe mode may be activated when the tampering activity is detected.

When the male connector is inserted into the female connector, a locking action is performed using the physical lock 62. The user can then perform a user input process to activate the device.

In the present embodiment, the device 10 is unlocked by a user performing a two-stage unlocking process. In particular, a user enters user input data to unlock the magnetic lock and de-activate the system, thus deactivating the sensors and alarms. When deactivated, the user can then use the key on the physical lock 62 to unlock the cable 18 from the engagement mechanism. A user can then disengage the cable 18 from the engagement mechanism 20, allowing the cable to be retracted into the housing 14.

The locking mechanism 22 is configured for locking the retractable cable 18 and/or the engagement mechanism 20 thereby to prevent further movement of the retractable cable 18 from the retractable cable system 16 and/or to prevent disengagement of the retractable cable 18 from the engagement mechanism 20.

In some embodiments, a deactivation button is provided inside the housing 14 to switch off the function of the product independent of the input device.

A closeable flap is provided as part of the housing 14 at the second connector 58 to cover and protect the connector when not in use. The closeable flap or a further closeable flap is provided that can be closed over the connection formed when the first connector is connected to the second connector. A similar flap is also be provided to cover the male connector when retracted and sat in its recess.

In the present embodiment, the second connector 58, the recess for the first connector 56, the key pad device 60, and the aperture for the retractable cable 18 are provided in the door 44 portion of the housing 14. However, it will be understood that in other embodiments, these may be provided at other positions on the housing.

As described above, the locking device 10 has one or more alarms and/or other security devices connected to the tamper detection circuitry 26 such that the tamper detection circuitry 26 is configured to perform one or more security actions using said one or more alarms and/or other security devices in response to detecting tampering activity with one or more of the engagement mechanism, the housing 14 and/or the cable.

In the present embodiment, the locking device 10 comprises an audio alarm device and a visual alarm device. The communication circuitry 28 and location circuitry 30 also operate as a security device. The visual alarm, audio alarm and communication and location circuitry are provided inside the housing 14.

In the present embodiment, the audio alarm device is configured to produce a fist alarm, which is a siren sound. The audio alarm device is also configured to produce an audio recording. The audio recording will describe, using spoken language, the tampering activity that is occurring. For example, the audio recording will state "this bicycle is being stolen". The audio alarm device comprises a speaker.

In the present embodiment, the visual alarm device has a light source 48 configured to be pulsed. In the present embodiment, the light source is a flashing light, in particular, a high intensity strobe fluorescent light. However, it will be understood that different colours and types of light source are suitable.

Vents or other suitable openings are provided in the housing 14 at the positions of the visual and audio alarm devices. The vents or other openings are sealed to prevent water penetration.

One or more of the audio and/or visual and/or further security devices are configurable to produce alarms at different frequencies. For example, immediately after tampering, an alarm is continuously produced for a first period, for example for 30 minutes. Following this first period, an intermittent mode is activated, in which the alarms and/or security device are operated less frequent for a second period. By providing different frequencies of operation, battery life may be preserved for the alarm devices and/or security devices.

The communication circuitry 28 is configured to send an electromagnetic signal in response to detection of tampering activity. In the present embodiment, a SIM card 54 is provided inside the housing 14, as part of the communication circuitry 28, as shown in Figure 2. The communication circuitry 28 also included RF transceiver circuitry for receiving and transmitting wireless communication signals. In the present embodiment, the communication circuitry 28 is configured to send an alert message, in accordance with the short message service (SMS) protocol to a number stored in a memory of the communication circuitry, for example, on the SIM card. It will be understood that other messaging protocols can be used. The message is produced by the RF transceiver circuitry.

In further embodiments, the RF circuitry is configured to send messages in accordance with a wireless internet protocol. A remote receiver may be provided to receive messages from a plurality of different locking devices, and to relay and/or take further action on receiving these messages.

Location circuitry 30 has a location sensor for obtaining location data for the locking device 10 such that the communication circuitry 28 can send location information as part of the message. In the present embodiment, the location sensor is a GPS sensor.

The power source 42 is connected to the electronic components of the locking device 10. In some embodiments, as described in further detail below, further power source(s) are provided as back-up power sources. For example, a further power source is provided for the communication and/or location circuitry for sending emergency alerts.

The communication and location circuitry 30 are configured to provide an emergency message including location information in the event of tampering activity being detected. The communication circuitry 28 is configured to send an alert message at a pre-determined frequency for a pre-determined length of time or until deactivated. As a non-limiting example, alert message are sent every 5 minutes for a length of three days.

The alert message will contain location data determined by the location circuitry 30, for example, GPS coordinates. The alert message may also contain further identifying data, for example, a unique code pre-allocated to the locking device 10 or other user information.

In the present embodiment, the communication and location circuitry have a further power source 42 that is recharged continually form the main power source 42. The further power source 42 is configured to hold a back-up charge for powering the communication and location circuitry 30 in the event of tamper detection.

In the present embodiment, the communication circuitry 28, the location circuitry 30 and the tamper detection circuitry 26 are provided as a single processing resource for controlling the locking device 10. The processing resource is provided on a single printed circuit board (PCB) and the housing 14 is configured to receive and host the printed circuit board. In some embodiments, a further internal housing is provided inside the housing 14, for housing the printed circuit board and/or further components of the locking device 10. The housing 14 and/or further housing is configured to reduce tampering with the printed circuit board and susceptibility to electrical, magnetic, shock, force, or liquid. The PCB is connected to the power source, the alarm and sensor modules and both ends of the sensor wire.

In the following, the operation of the locking device 10 will be described. In use, a user positions the bicycle 12 (with locking device 10 attached) next to a further object, for example, a railing, for securing the bicycle 12 thereto. The user applies a force to the retractable cable 18 to pull the cable from the housing 14. The user, by continuing to apply a force, loops the cable around the further object and back towards the housing 14. The user may also loop the cable around parts of the bicycle 12, for example, the user may thread the cable through the spokes of the wheels and/or pannier racks. The user then engages the cable 18 with the engagement mechanism 20. The extracted cable 18 thus forms part a closed loop around the further object. When released by the user, the retractable cable system 16 retracts the cable 18 back into the housing 14 and reduces the slack present in the extended cable 18. The retractable cable 18 therefore tightens the closed loop formed by the cable 18 around the further object.

Once the cable 18 is engaged, the user can perform a locking and activation process on the locking device 10. In the present embodiment, a first step of the locking process is performed when the cable 18 is engaged. In the present embodiment, the first step of the locking process is performed automatically, however, in other embodiments, the first step of the locking process is performed manually. In particular, the first step locks the cable in place using the physical lock 62. The physical lock 62 locks the cable 18 in the engagement mechanism 20 and prevents the retractable cable 18 from being removed from the engagement mechanism 20. The locking mechanism 22 also prevents any further extension or movement of the cable 18 through the retractable cable system 16.

The user then enters a code into the keypad of the locking mechanism 22 to activate the device 10. In other embodiments, the device is activated by other means, for example, via the key-fob or mobile computer device. Once the code is verified by the user input circuitry, the user input device sends a control signal to turn on the processing circuitry 24 which in turn sends control signals to activate other components in the device 10. This step includes sending a control signal to the magnetic lock to lock the door 44. The processing circuitry 24 also transmits control signals to activate the sensor module 32, the alarm module 34, the communication circuitry 28 and location circuitry 30 and the tamper detection circuitry 26.

When activated, the tamper detection circuitry 26 monitors sensor output from the one or more sensors. If a person tampers with the retractable cable 18 when the device is active, the output from the sensors will indicate that tampering activity is taking place.

In response to determining that tampering activity is taking place, the tamper detection circuitry 26 provides control signals to the one or more alarms or security devices. In the present embodiment, on detection of the tampering activity, the tamper detection circuitry 26 controls the one or more alarms and security devices to perform the following security actions: transmitting, using the communication circuitry 28, a wireless security message for an owner of the object, activating an audio or visual alarm. The locking device 10 also obtains location data using the location circuitry 30. This location data forms part of the wireless security message. The locking device 10 is also controlled to be put into a fail-safe mode.

In the above described embodiments, the user engages the cable to automatically lock the cable in place and enters a code to activate the device, which also locks the magnetic door. In other embodiments, a two stage locking process is performed, which includes operating physical lock 62 using a key and then providing user input to the user input device 36.

To deactivate and unlock the device, a user first provides user input data to the user input device 36, in the present embodiment, to the keypad 60. On successful verification of the user input data, the device is deactivated, which includes turning off the sensor module 32, the alarm module 34, the communication circuitry 28, the location circuitry 30, the magnetic lock 44 and the tamper detection circuitry 26. When deactivated, a user can then release the cable from engagement mechanism 20 by operating the physical lock 62 using a key.

The housing 14 is a robust outer casing with rounded features. The housing 14 is made from durable and substantially unbreakable surface material. The housing 14 has one or more strengthened areas, in particular, where there are apertures. The size of the housing 14 of the product for primary uses will be approximately 120mm x 120mm x 50mm.
