The present invention relates generally to improved methods and apparatus for mobile storage and transportation of cash or other valuable assets. More particularly, the present invention relates to advantageous aspects of an improved transport bag with tampering or theft countermeasures, such as triggered smoke deployment, a siren, or the like and retrofit systems for modifying existing asset transport bags and the like.
There are a number of risks faced by those that are required to transport valuables from one place to another, such as from a business to a place of safe keeping, for example. A primary risk is that of robbery of those valuables while in transit. A secondary risk is that of theft by a courier given the task of transporting the valuables. Several approaches have been taken to reduce such risks, but these approaches are often costly and excessively complex.
In one prior art approach, relatively large and complicated portable cases have been designed to protect valuables. Such cases feature formidable physical security and tamper monitoring systems. European Patent Nos. 2,347,078 and 2,510,506 teach transport cases that feature a dispensing system and electronic monitoring system that are designed to devalue cash inside with a devaluing agent such as glue (2,347,078) or ink (2,510,506) when the transport case is tampered with. Another transport system is taught by Villiger in U.S. Pat. No. 7,707,950. This system is large in physical size and weight to support an elaborate dispensing system. The complexity and size of such approaches make them costly.
In an alternative approach, smaller cases have been created that reduce the cost, complexity, and weight of devaluing agents designed for 100% coverage of cash stored within and instead focus on generating attention in the event of a robbery. Several such products use loud sirens and can be configured to release smoke or dye inside the case to partially stain the contents and the robber. The tamper detection methods used tend to be simpler than the large products addressed above and typically involve the use of panic buttons and or tethered pull cords.
In one such example, a transport bag apparatus that incorporates a staining agent to mark cash stored within, but not necessarily to the level of destruction or devaluing is addressed in U.S. Pat. No. 5,790,028. This patent also includes a high voltage generator for the purpose of electrically shocking a robber, and a siren to draw attention, as well as, a mechanism for remote wireless activation of these countermeasures in response to an attempted theft.
Another example is a portable personal security system as taught by U.S. Pat. No. 5,748,089 in which a smoke or sparkler device is ported intentionally outside of a transport bag for the purpose of grabbing attention and alarming a robber rather than staining contents inside the bag.
These types of systems may require that the custodian manually deploy the countermeasures by pushing a panic button or switch or otherwise rely on rip cords or breakaway features to set off the alarm. In a snatch and run robbery, the custodian may not have time to realize the attempted theft is taking place and manually activate the alarm feature. Rip cords and break away features are also prone to false activation causing unnecessary public distress and costly smoke replacement. These systems also fail to monitor whether the bag itself is actually securely closed.
U.S. Pat. No. 6,029,448 proposes a method for monitoring whether security bags are securely locked by monitoring the state of a specially designed zipper lock mechanism. This patent teaches a method of combining a standard zipper lock with a circuit board for the purpose of monitoring lock closures. The standard style of zipper lock described has the limitation of needing to be sized precisely to fit a particular zipper housing body. A second limitation of this approach is it requires carefully backing the zipper body into the lock housing prior to pressing down on the zipper lock capture mechanism. If alignment of the zipper body is not proper, the zipper lock will not engage and the bag will not be secured.
Some of the recent systems use wireless radios to monitor the proximity of the case to a transporter, such as a guard, and are configured to deploy when the case gets too far from the guard. Examples of these types of system are produced by HDH Security Systems, Ltd. and in particular include their Proximity Case™ model. Such systems suffer from employing a method of pairing the case to a guard's key fob that are complicated to perform or are not supportive of simple reassignment to other guard fobs as would be helpful in a deployment of secure cases in a fleet of users. They also lack the ability to track whether the case is securely closed and locked and to keep track of which guard has maintained custody of the case.
Among its several aspects, the present invention provides an improved mobile valuables transport system that advantageously uses advanced, cost-effective tamper detection techniques combined with a smoke and siren system that can be configured to a wide range of bags including those optimally suited for armored car companies and that address a simple method of configuring bags to guards, other couriers, or the like.
It is one objective of the present invention to provide an electronically monitored transport bag system wherein each bag is characterized by having a wireless radio interface that is in communication with a guard's fob. The fob is securely and uniquely paired to the transport bag. The bag is deemed under control of the guard when the fob is determined to be within a first predetermined distance. Once deemed outside of the guard's control, the bag security system is configured to deploy theft countermeasures, such as a loud siren and or smoke for the purpose of generating attention and compelling a thief to stop a robbery.
Another objective is to provide an arrangement of tamper detection electronics and a power source within a plastic module mounted to one wall of a valuables containing bag with at least one port that vents smoke and emits sound outside the bag.
It is a further objective to provide a two piece security module with an interior piece fastened inside a valuables containing bag and an external piece fastened outside the bag. The external piece contains a smoke pack and siren with vents to direct the smoke and sound release. The internal piece contains tamper electronics and a power source. The two pieces are connected with an electrical linkage carrying power and data signals and may be mechanically connected with either rigid fasteners through the bag wall or a fastener that wraps around the zipper opening of the bag.
It is another aspect of the invention to provide a method of securing a zipper fastener, such as a zipper body, and electronically detecting that the zipper lock is engaged.
It is a further objective to provide a unique and a secure pairing method to associate a fob with a bag. In one approach, this pairing can only occur when assisted by a separate pairing device without the use of a pairing button on or in the bag itself. The pairing device can be in the form of a radio communicating using the same spectrum as the fob or in the form of an alternate out of band radio.
It is another objective to provide a method of operating a bag with multiple authorized guards simultaneously.
It is another objective to provide a tamper detection system for a bag containing valuables that combines an ambient light sensor configured to look inside a normally dark bag, a zipper lock detector, and a fob proximity detector as addressed further herein.
It is yet another objective to provide a method of ensuring a zipper bag is closed and locked using a magnetic field sensing approach and permanent magnets mounted on both the zipper body and lock armature.
It is another objective to describe a bag security system within a single rigid module combining a zipper lock, a siren, a smoke emitting device, a wireless radio, a battery power source, and a display.
To such ends, the present invention provides advantageous mechanisms to detect efforts to open a cash transport bag after it has been closed by an authorized person and to trigger a smoke dispenser in response to such detection. The present invention may be suitably applied to both newly manufactured cash transport bags, as well as, being adapted as a retrofit to a wide variety of existing bags.
A more complete understanding of the present invention, as well as, further features and advantages of the invention, will be apparent from the following discussion and the drawings included therein.
In
Operational details of a first and presently preferred embodiment of the invention are summarized in conjunction with a discussion of
One user feedback method involves the use of a buzzer 614 and display 616. The display is preferably an OLED graphic display but may also be implemented as standard discrete LEDs, a 7 segment display, LCD display, or vacuum florescent display.
Further mechanical design details of the presently preferred embodiment of the invention are shown in
A lock axle capture feature 309 is designed to ensure the axle of lock 201 will rotate in a precise defined region over the lid 301 thereby confining the rotation motion to over the top of a rotation sensor located on circuit board 330. The axle of the lock is extended towards the front shell enclosure 301 by attaching a magnet holder cap 206 seen in
A second magnet placed on the bottom of the zipper pull body can be used to determine that when locked, the zipper body is in the proper position behind the locking cam 203. The field from the zipper body magnet will deviate the measured readings on the magnetometer detector 331 in a predictable manner such that the presence or absence of the zipper can be inferred. For this enhancement, it is necessary to either slot an opening in the metal zipper back plate 205 below the zipper pull body such that the magnetic field lines can pass through to the detector or to use a stiff plastic material transparent to magnetic field lines in place of metal for the back plate. Alternatively, a separate magnetic field sensor, such as a multi-axis magnetometer, Hall sensor, or a reed switch could be used to detect the presence of the zipper pull itself independent from the one used for detecting the lock orientation to simplify the controller signal processing.
As shown in
The rear of the control module enclosure 302, as shown in
As shown in
In the presently preferred embodiment of the alarm module 400 shown in
Siren 410 preferably produces a 120 dBA swept sine wave output at one foot distance and is connected to power via a cable harness connector to a connector 419 located on circuit board 415.
Circuit board 415 receives power signals for both smoke generator 411 and 412 and the siren 410 through connector 418. Connector 418 may also contain a communication bus such as a UART or I2C to communicate to sensors located on circuit board 415. Such sensors may include temperature and humidity detectors that are configured to monitor environmental conditions within the alarm module for the purpose of detecting smoke deployed via a detected rise in temperature proximate to the smoke generator, or for determining if the smoke generators need to be replaced due to prolonged exposure to excessive temperature or humidity as smoke formulations may be sensitive to such environmental excesses.
Preferably, the smart transport bag uses a Bluetooth low energy radio (BLE) 318 as a primary way of monitoring proximity of the STB from an authorized guard. The guard's fob contains a radio that communicates with its paired STB periodically by advertising its identity. The STB's radio records the fob identity along with the signal strength to determine an approximate proximity of the guard to the STB.
At times, it may be advantageous for there to be multiple assigned couriers for one particular STB simultaneously. Each courier identified with a unique key fob that is pre-associated with the STB. In the event of two simultaneously paired key fobs, the three proximity regions are defined as shown in
On a daily basis, bags can be reassigned to different couriers or guards. The mechanism for assigning guards to a particular bag is to place the bag in a special pairing mode. Conventionally, to pair two radios together, there is a pairing button that is pressed. One such button could be located on the bag itself. The drawback to a pairing button on the bag is that it can be accidentally pressed, for example, by contents within the bag. A second drawback is that the guards would have the ability to re-pair the bag at their own discretion by pressing the button. A third drawback is that designing a button into the bag module, that is either mechanically protected from false activation, or secured behind an access door making it inaccessible to the guards, is costly.
The present invention may advantageously employ a new pairing process 900 shown in
If the pairing module detects a fob signal strength above a pairing threshold in step 914, for example, for the first fob, pairing is secured to the first fob in step 916, the pairing module then provides an indication that pairing has been successful in step 918, for example, by beeping twice. In step 920, a display may also display a success message for pairing the first fob with the bag. The first fob can then be removed from the top of the pairing module in step 922. If the bag were to be paired with only a single fob, the pairing timer would time out and process 900 would end.
However, in the example shown, the second fob is held on top of the pairing module in step 924. In step 926, the pairing module detects that the fob signal strength is above the pairing threshold and the pairing timer is adjusted for a new timing period, such as 30 seconds, in step 928. In step 930, fob strength from the second fob is detected above the pairing threshold and pairing of the second fob to the bag is secured in step 932. The pairing module beeps twice in step 934 and a display that pairing has been successful occurs in step 936. In step 937, the second fob is removed. In step 938, the pairing timer times out. In step 940, pairing is complete and the pairing state is exited.
In an alternate pairing implementation, the supervisor can use a privileged secondary radio source to place the bag in pairing mode as shown in the process 1000 of
In both pairing approaches described above, the bag is first paired to the supervisor's device to exchange credentials for authentication purposes. The result of proper authentication is the bag entering the pairable state where it actively looks for guard fobs at the primary proximity radio band (2.4 GHz). If guard fobs are detected to be within close proximity while in pairing mode as measured by RF signal strength (preferably within 6 inches), then the bag will proceed to pair with the guard's fob. If additional fobs need to be paired to the bag, they can continue by presenting subsequent fobs one at a time in close proximity to the bag, a process illustrated in
During daily operation, it is anticipated that the STB is issued at the beginning of a shift to a guard by a supervisor using the above described pairing procedure. Throughout the day, the guard loads the STB with valuables then zips the STB closed and turns the key to the locked position. The locking of the STB is detected by the controller and causes the STB to enter the armed state. During the armed state, the guard carries the fob in proximity to the STB to ensure the STB is in the secure region of proximity to the fob. When the guard reaches the intended destination, the key is used to unlock the STB. The controller detects the motion of the cam to the unlocked position and disarms the STB. Trips like this can continue multiple times throughout the day. At the end of the shift, the guard returns the STB to the supervisor who then plugs in the charger. Upon activating the charger, the controller erases the pairing list of all connected fobs such that the STB can be assigned to a new guard or group of guards the next day.
