20170367452
Travel today is full of delightful new experiences, but also fraught with terrifying new dangers. Terrorism and other threats to every mode of transportation appear almost daily. A travel case that protects one's possessions, the peace of mind of one's loved ones and possibly one's own life would be useful to today's world traveler.
A travel case according to aspects of embodiments of the invention may include one or more of any of the following features and/or elements either individually or in combination. It is contemplated that the invention may include any combination and/or permutation of these features.
The travel case solves newly-recognized problems in the art in new ways. It has been observed that rescue and recovery of travelers and their belongings may be extremely difficult as a result of incidents of catastrophic accident or terrorism taking place in remote, often oceanic locations. These and other related problems were previously seen and addressed only from the point of view of improving or enhancing black box functionality to aid in the location of a downed aircraft, and the point of view of improving or enhancing the regular communication of aircraft location and navigation information to satellite and/or ground stations to pinpoint the path, speed, altitude, etc. of an aircraft immediately preceding a catastrophic incident. But, no one has considered that each passenger or piece of equipment carried aboard a plane, vessel, or vehicle may provide the means for self-rescue or, in the event of an utter catastrophe, location and recovery of the wreckage. The present invention may have application in any field of endeavor in which valuables may be transported by vehicle from one location to another, such as when valuable documents, cash, jewelry, sensitive equipment, or other valuable items are hand-carried. As will be understood when reading the following description, the travel case may be a traveler's suitcase, a briefcase, an attaché case, an equipment case, or any other similar travel case.
A travel case includes a case body defining an interior cavity in which to carry articles and an exterior shell; an inflatable floatation aid fixed to the exterior shell; an inflator in communication with the inflatable floatation aid, for inflation of the inflatable floatation aid; and a locator beacon fixed to the exterior shell, including a communications transmitter capable of signaling a remote party and a geo-locating apparatus. In a variation, the locator beacon employs a Global Navigation Satellite System (GNSS) to determine location. In a further variation, the GNSS is the US Global Positioning System (GPS). In yet a further variation, the locator beacon employs radio tower triangulation to determine location. In another variation, the inflatable floatation aid is separable from the case body and fixed to the exterior shell by an extendible tether. In yet another variation, the inflator operates automatically. In a further variation, the inflator operates by introduction of water that may dissolve a pill-cage pill, or may operate by submersion, which may be detected via hydrostatic pressure sensing. In another variation, the locator beacon operates automatically responsive to operation of the inflator. In a further variation, the travel case further comprises: sensors sensitive to environmental parameters of the travel case; wherein the locator beacon operates automatically responsive to sensor inputs indicative of a catastrophic event. In a yet further variation, the sensors include at least one of a GPS locator, an accelerometer, and a magnetometer. In an even yet further variation, the travel case includes a processor that activates and prevents operation of the inflator and/or that activates and prevents operation of the locator beacon. In other variations, the locator beacon operates automatically on a periodic basis. In another variation, the locator beacon is connectable to a two-way, wireless data network, whereby the locator beacon can send and receive messages to a recipient endeavoring to locate the travel case after it has become lost. In a further variation, the locator beacon operates on demand, responsive to an operator. The locator beacon may be a search and rescue beacon operating on 121.5 MHz and/or 406 MHz, a beacon communicating with a cell-tower, a satellite phone service. In another variation, a programmable display affixed to the case body on which origin, destination, owner, and/or vessel identification information is displayed. In yet another variation, the programmable display is affixed to the inflatable floatation. In even yet another variation, the programmable display is of a type that retains on display a most recently programmed data set in the event of a power failure. The programmable display may be an electronic ink display.
In the following description reference is made to example implementations. It should be understood that other implementations are possible, and that these example implementations are intended to be merely illustrative.
The following section provides several illustrations of implementations of the travel case.
The travel case according to aspects of the present invention may include a number of features, including features that safeguard the travel case from sinking if separated from the vehicle in which it may be carried, and features that aid in identifying the location of the travel case if an unexpected or catastrophic event befalls the vehicle in which it may be carried, and features that communicate that location to potential search and rescue personnel or others in the event of a separation, unexpected, or catastrophic event.
The travel case of the present invention includes any desired combination of conventional components and aspects that will be described only briefly, here, to permit the inventive aspects to be understood more clearly. For example, the case may be based on a hard-shell design or soft-shell design. Cases to which the invention applies may include zipper closures, snap locks, keyed and combination locks, and other conventional closures employed on travel cases. Some travel cases to which the invention applies may include water resistant shells and closure seals providing any desired degree of water resistance from none at all to resistance to impact immersion and submersion to a set depth. Case interiors may include various packing aids and options, such as toiletry bags or compartments, lingerie pockets, folding frames and hangers for suits, shirts, and other clothing susceptible to creasing, etc. A special compartment accessible from the outside of the case may be provided to store emergency hydration and/or dry nutrition products. Hydration products may be stored in either a TSA-compliant one-quart package for liquids in 100 ml or smaller containers, or in a TSA-non-compliant manner if permitted for the travel plans of the user.
The term travel case should be understood to include cases for equipment, cases for special goods such as musical instruments or jewelry shipping containers, and other cases that generally resemble travel cases. Larger cases used as shipping containers for larger goods or larger quantities of good may also be considered to be travel cases for the purposes of this application. In general, travel cases are containers for personal articles, equipment, etc. that are small enough and light enough when loaded to be handled by an individual passenger or traveler. Excluded are containers whose primary purpose is to secure and deploy such safety equipment as EPIRBs, flight data recorders, vehicle data recorders, and the like.
Aspects of the invention include a travel case fitted with apparatus to provide individual passenger safety, tracking, and recovery features not found in conventional travel cases. Other aspects of the invention include other diverse and larger cases and containers fitted with apparatus providing additional safety, tracking, and recovery features not found in conventional cases and containers. Other aspects of the invention include methods for deploying safety, tracking, and recovery equipment and features from travel cases, other cases, and containers.
There has previously been no motivation to provide such functionality at an individual passenger level, in travel cases, because of several factors. One factor is the complete reliance in the transportation industry on vehicle-level systems, rather than passenger-level systems, which add cost and complexity, and were considered to have insufficient reliability for general reliance. Another factor is the space taken away from passenger luggage space to incorporate conventional safety equipment into typical travel cases. Yet another factor is the expectation that highly durable, specialty safety equipment is more likely to survive a catastrophic event than personal electronics or the like.
It is understood and intended that the aspects of the invention described below intrude minimally, if at all, into the packing volume of the travel case. Rather, the features described are designed to be flat and integrated with the hard or soft shell materials, or occupy volumes within the shell that are unused or under-used in conventional case designs, such as those volumes that become unusable due to the integration of handles or wheels in the case body.
The exterior of the body of the travel case (See
The inflatable bladder may be formed of a substantially gas-impermeable membrane of solid material, a composite matrix such as a coated fabric, or any other suitable material that is flexible, compact when uninflated, and substantially gas-impermeable. The inflatable bladder defines an enclosed volume, and has an edge defining an opening through which the bladder can be filled with a gas to provide buoyancy. One commonly used buoyancy-producing gas is CO2. The bladder material should be substantially gas-impermeable to the particular gas selected, such as CO2.
Attached and sealed to the opening of the bladder is an automatic inflator apparatus, such as used in conventional inflatable life vests and the like (not shown). The automatic inflator may use compressed CO2 supplied in standard canisters, or another suitable gas source whose presence aboard commercial air carriers is permissible.
One basic criteria for operation of the automatic inflator apparatus is entry into a water environment. As discussed below, detection of a catastrophic event will supplement and/or mitigate operation of the automatic inflator. The water entry aspect of operation of the automatic inflator may be triggered by hydrostatic or hydrodynamic action, as desired. Introduction into the trigger apparatus of water, submersion of the trigger apparatus, or hydrostatic pressure observed at the trigger apparatus can trigger the inflator, in the presence of other suitable inputs described below, as desired. One suitable actuator (Secumar® actuators made by Bernhardt Apparatebau GmbH u. Co. of Holm, GERMANY) is a conventional pill-cage actuator triggered by dissolving a pill-shaped element when immersed for a sufficient time in water. Other suitable actuators triggered by a water-soluble element or link are known. Another suitable actuator (Hammar® actuators made by Hammar AB of Göteborg, SWEDEN) is a hydrostatic trigger activated by immersion of the actuator to a set depth of water, i.e., by water pressure of a set amount. Also suitable are electronic and electromechanical sensors that are not sensitive to the direction in which they are mounted or suspended, such as used to detect flooding in residential, industrial, and shipboard spaces, among others.
The entire floatation apparatus should produce sufficient buoyancy to keep the entire travel case at or near the surface of a range of typical salt- and fresh-water bodies found across the world at various temperatures. A typical minimum requirement might be somewhat above 50 lbs. (or, whatever the normal maximum weight of a fully-loaded piece of hand luggage for air travel might be at the time the travel case is designed). The floatation apparatus can be arranged to remain affixed to the surface of the travel case when deployed (see
If the floatation apparatus (
If the floatation apparatus is provided with sufficient buoyancy, the travel case can provide personal floatation in the event the travel case is in reach of its owner at the time catastrophe strikes. In such instances, the floatation apparatus should include strapping, buckles, and looped handholds and/or footholds to facilitate fixing the floatation apparatus to the user, even after the user and the apparatus are in the water (
Location-finding apparatus may be also included, to aid in locating the travel case and other debris dispersed in a catastrophic event, as shown in
The location finding apparatus can communicate the location found with an owner still in possession of the travel case through a control panel display 107 (see also
Control and interface software accessed through the control panel 600 is illustrated in
If the interrupt event was a key press 1002, then the key pressed is buffered 1005 in a key buffer memory. The contents of the key buffer are then interpreted 1006.
Some keystrokes or combinations do not signify anything because a complete command or item of data is not represented thereby; in that case control returns 1007 to the idle state 1001, while the keystrokes collected in the key buffer are retained until confirmed to be commands or data to be interpreted, or if confirmed but interpreted to be garbage are then flushed from the key buffer. Certain keystrokes or combinations of keystrokes are interpreted to be commands 1008, and cause the system to execute those commands 1009, such as displaying on the screen luggage tag information previously stored in data memory of the system. After commands are executed 1009, control returns to the idle state 1001.
In addition to commands to be executed, data can be input, such as the baggage tag and destination information for the current trip and the type of vehicle on which the travel case is to be carried. If the interpretation of the key buffer 1006 determines the content to be input data 1010, the data is then stored 1011, before returning to the idle state 1001.
If a touch screen or similar input device is included in control panel 600, then gestures received 1003 through the touch screen or similar input device are interpreted 1012. The gestures received and interpreted are then executed 1009 similarly to commands received by keystroke. Gestures may have meanings evident from elements of a Graphical User Interface (GUI) displayed on the control panel display or may cause other predefined manipulations of the system defined by the underlying GUI software. After gestures are executed 1009, control returns to the idle state 1001.
Each time the sensor suite produces new sensor values 1004, sensor output data 1013 is collected. This exemplary embodiment employs an interrupt-driven model, but a polled sensor system may also produce the sensor output data 1013 on a timed basis instead. The sensor output data is then stored in a memory, whereby sensor history data is updated 1014. Sensor history data is interpreted 1015, to determine whether the travel case is undergoing normal motion for the type of vehicle in which it is being carried, or whether the travel case is undergoing motion representative of a catastrophe befalling the vehicle in which it is being carried. If the interpretation is that a catastrophe has occurred 1016, then the processor will execute various protective actions 1017, such as triggering the inflation of the floatation apparatus or sending search and rescue system (SARS) messages or other communications indicating the status and/or location of the travel case. The case will remain in this state indefinitely until reset or the batteries expire.
The various inputs to the executive through the control panel 600 may affect such behaviors as displaying a virtual luggage tag on demand, applying different algorithms to sensor inputs in order to determine the occurrence of a catastrophic event, etc. User interface and executive software such as would be suitable for this application is well-known in the computing arts.
A subsystem can also be provided, if desired, by which the executive periodically flushes the buffers of data that is no longer current or relevant. For example, a timer can trigger a process to periodically, after a period of inactivity, or based on some other suitable criteria, stuff the key buffer with a command to flush buffers, in some implementations, thus overriding prior inputs and performing the necessary flush.
In order for the antenna 401 of the location finding apparatus to be exposed to the satellites or towers from which location information is derived, the location finding apparatus is attached to that part of the travel case that will float at the water's surface and remain oriented above the water's surface as described above. It should be affixed to that component in such a way as to face up when deployed as a result of a catastrophe. If the floatation apparatus is tethered to the travel case, which is retained below the surface, the location finding apparatus is suitably attached to the floatation apparatus. If the floatation apparatus is affixed to the travel case to form a unit that floats entirely at the surface, the location finding apparatus should be affixed to a surface of the case that the floatation apparatus causes to float upwardly as described above.
In order to communicate the location of the travel case to friends, relatives, search and rescue teams, or others, the location finding apparatus should be connected to communication gear that could send a message by a suitable channel (
The travel case can include sensors (
The software that receives the sensor input history and performs the analysis of that history is illustrated by the flow diagram of
The software illustrated in
During periods of time when the processor determines that a catastrophic event is unlikely to have occurred, the processor outputs may include inhibit signals amongst the output signals and operational controls provided to the inflation apparatus and the location finding apparatus. The inhibit signals would prevent deployment of the inflation apparatus and prevent communication by the location finding apparatus of an emergency message. During periods of time during or after determining that a catastrophic event is likely to have occurred, the processor may enable operation of the inflation apparatus and the location finding apparatus by similar output signals and operational controls, but with inverse significance. Operation of the inflation apparatus may be controlled by the processor (as described above) or may provide a control input to the processor indicative of the existence of a state of catastrophe, depending on the desired behavior of the travel case.
The location finding apparatus can optionally operate automatically on a periodic basis either instead of or in addition to being controlled by the processor. In addition, the user can manually operate the location finding apparatus using control panel 600, for example to check location and/or send an “OK” message through a non-emergency channel or an emergency message through an emergency channel. The user simply enters suitable, pre-determined commands through the executive program 1000 using the control panel 600 as described above to trigger the desired message.
The executive program 1000 can receive manual commands and activate desired operations if a person with the travel case observes a catastrophic event. For example, if a person with the travel case observes a hijacking in progress on board an aircraft on which they are travelling, the person can enter commands to initiate an emergency message transmission and/or arm the inflation actuator. The command can be entered through the control panel 600 and the executive software 1000. Amongst its communication channels, the travel case can include a Bluetooth or other short-range wireless communication channel by which commands to the executive program 1000 can be transmitted via a cell phone or another mobile device. (See also,
The travel case can function as a fully integrated system capable of providing one or more of the following functions: detecting and alerting others to an incipient or ongoing catastrophic event; protecting contents from environmental damage; aiding in the location of a vehicle, its contents, and/or its passengers after suffering a catastrophic event; and providing some level of support to survivors of a catastrophic event. In order to function as such a fully integrated system, a number of the components parts described above should be constructed and arranged to cooperate to produce desired functional results.
The components responsible for detecting a catastrophe may be integrated with those for sending an alert and/or those for triggering deployment of a floatation aid. These components must function without interfering with the operation of the vehicle in which the travel case is carried and without raising any security concerns with respect to the vehicle.
For example, premature or unneeded deployment of the floatation aid should be avoided. This may be accomplished through the use of multiple sensors and well-developed algorithms for characterizing the environment and circumstances over time of the travel case. An immersion trigger has been suggested above as an appropriate sensor and trigger system for deploying floatation when the travel case is immersed in water. A more robust system could arm the immersion trigger only when GPS position information indicates passage over water or when incremental changes in GPS position information indicate an erratic or otherwise unusual travel path of the vehicle. Another more robust system could arm the immersion trigger when accelerometers detect unexpected or unusual sudden changes in velocity (speed and/or direction). A simple pressure switch system on the handle(s) of the travel case could prevent arming of the immersion trigger while the case is being hand-carried, and permit arming of the immersion trigger when the case is set down or loaded into the vehicle.
Travel cases of various sizes could accommodate the inventive system. For example, cases for airline passengers' personal articles could incorporate some or all of the features described, and be small and free enough within the airline cabin to either be carried out with a passenger in an emergency, or to float free in the event of a massively destructive event. The low mass of such small items would help preserve them in a high-energy, destructive event, allowing them to serve their function of aiding in the location of the remains of such an event. Larger suitcases and equipment cases could incorporate additional features, larger battery power supplies, and larger, more versatile, rescue features, such as rudimentary rescue raft flotation.
Use of the invention both for personal possessions of travelers and for other articles transported in portable cases could reduce insurance rates for those forms of transportation of small articles and provide additional management controls to logistics managers responsible for the transportation of such small articles. The limited size and weight of the cases, for example suitcases carried by air are often limited to 50 lbs, reduces the energy required to be absorbed by the case upon an impact. This has resulted for example in passenger possessions being amongst the articles recovered intact from an otherwise catastrophic aircraft loss.
Various combinations of the foregoing features and elements can be made, and are contemplated as within the scope of the present invention.
