The present invention relates to smart portable containers for transporting items while traveling comprising electronic devices. Such smart containers provide for centralized storage and use of electronic devices with modular embodiments of the invention being configurable to accommodate travelers anticipated needs.
Since the invention of the solid state transistor, advances in electronic based technology have had a dramatic impact on human existence. Such solid state electronics provided a means for sending a man to the moon and probes across the galaxy. Electronic computing devices hundreds of times more powerful than the computers used to send a person to the moon are now commonly owned by ordinary people. Wireless communication devices that were once only props in science fiction movies are now commonly used. Indeed, such advances in electronic technology have been leveraged to improve the standard of living of the general populace to a level unthinkable just a few generations ago. One result of such advances is that most people routinely carry at least one electronic device, such as a cell phone, a PDA, electronic watch, a wireless remote for communication with a vehicle, a garage door opener, a DVD player, a music player (e.g. MP3), etc.
Travel is one area in particular that advancements in electronics have had a striking impact. Modern computing devices have given engineers the ability to design bigger and faster transportation devices, such as the modern jet. With the advent of such technology, long distance travel has become increasingly common. For example, as a result of affordable long distance travel, modern industries have been marked by a strong internationalization of their markets, requiring global business strategies to achieve effective cross-border markets. Such business strategies frequently require employees to travel, and when they travel, taking their electronic devices with them.
Similarly, when people go on vacation, affordable long distance travel provides the opportunity for the vacationer to visit in far off locations, perhaps in a foreign country. In fact, the tourism industry has reported a dramatic change in its structure over the last few years. Travelers' wish for more frequent, but shorter travel, last-minute reservations, global advice, and service quality. Electronic devices providing access to communication systems provide reliable information on facilities and services offered in unfamiliar locations. Such electronic devices allow the traveler to stay in touch with a service provider as well as consult various sources of information to assist them in their decision making processes.
Considering the above information at least two things seem certain; people are going to travel, and when they travel, they are going to take at least one electronic device with them. Examples of travelers include a business man on a business trip, a person on vacation, a hiker in the great outdoors, and a student moving between home and classes. When people travel, they frequently take a container for housing and transporting items. Luggage is a familiar device used by people to store and transport items they wish to take along with them while they travel. Hikers, for example, often carry their luggage on their backs in a container referred to as a backpack. Students also carry luggage known as book bags. Bikers may have a utility belt. The hiker, student, business traveler, and vacationer will likely have different luggage needs. Indeed, two different hikers may have different needs depending on their anticipated environment and/or destination. Thus, the devices that a traveler decides to take along on a trip may also vary. Consequently, the luggage needs of the traveler will likely be different depending on both the purpose of the travel and the travel destination.
Luggage (portable container) design is one area that has escaped the evolution resulting from the above described technological advances. Some prior art systems may have adapted somewhat to accommodate new ways of storing items during travel. However, such prior art systems have not adequately addressed the need for transporting various electronic devices frequently used by travelers. More specifically, what is needed is a smart container system that provides a centralized area for charging, storing, and/or using electronic devices. Additionally, such a smart luggage system should be configurable allowing the traveler to configure such luggage based on the travelers' anticipated needs.
Some of the objects and advantages of the invention will now be set forth in the following description, while other objects and advantages of the invention may be obvious from the description, or may be learned through practice of the invention.
Broadly speaking, a principle object of the present invention is to provide a smart container system comprising a centralized area for charging, storing, and/or using electronic devices.

Other objects, features, and aspects of the present invention are disclosed in or may be determined from the following detailed description. Repeat use of reference characters is intended to represent same or analogous features, elements or steps. It is to be understood by one of ordinary skill in the art that the present discussion is a description of exemplary embodiments only, and is not intended as limiting the broader aspects of the present invention.
While the particulars of the present invention and associated technology may be adapted for use with any type of container used to transport items while traveling, the examples discussed herein are primarily in the context of travel luggage, hiking backpacks, and book bags.
For the purposes of this document, a smart container is any receptacle for holding items while traveling and associated with electronic devices as described herein. Exemplary smart container (10) includes a compartment for holding items comprising first section (12) and a second section (14). First section (12) is releasably associated with second section (14) so as to form, when closed, a inter void for holding items inside the container. It will be appreciated that the container may be comprised of any number of sections as well as a plurality of compartments for holding items without departing from the scope of the present invention. Additionally, the smart container may comprise only one section configured with a closable hole, for example. One exemplary embodiment of such a container is a duffel bag comprising a string around the perimeter of a hole in one end of the duffel bag.
Smart container (10) comprise at least one electronic module (20) associated with a module bay (described later).
First section (12) may be releasably associated with second (14) via an electronic lock associated with a processing device. Similarly, each electronic module may comprise an electronic lock for securing the modules. Such electronic locks are electrically associated with a processing device configured for controlling the open/close status of the electronic locks based on user input as well as other control signals. Such technology will be discussed in more detail below.
For embodiments comprising at least one wheel, at least one magnetic device may be associated with such wheel and configured for at least one of: (a) generating energy, and (b) providing a moving force to assist in moving the smart container. For this configuration, the magnetic device may be a generator formed by associating a permanent magnet with a wheel. At least partially surrounding the permanent magnet is a coil of wire. When the wheel is rotated, a rotating magnetic field is generated. The magnetic flux from the rotating magnetic field induces a current in the coil of wire. The coil output is electrically associated with power bus (110) or directly to an electronic device associated with smart container (10). With this configuration, the magnetic device can power an electronic module and/or recharge a power source when the smart container is moving and generating a rotating magnetic field.
Alternatively, a magnetic device may be configured for generating an oscillating magnetic field. One embodiment of a magnetic device configured for generating an oscillating magnetic field is a magnet associated with a rod and configured to slide back and forth across the rod when the smart container is moved. A coil of wire surrounds the rod so that the oscillating magnetic flux lines induce a current in said coil. The output of the coil is electrically associated with power bus (110), an electronic module or integral electronic device.
For yet another embodiment of the invention, the magnetic device may be a motor-generator. A motor-generator is a magnetic device that may be used as either a motor or a generator. For this configuration, the magnetic device is associated with the smart container's (10) power bus (110) via electrical components such as a diode, transistor, etc., so that current only flows in the appropriate direction. When used as a motor, the magnetic device provides a moving force to assist in moving the smart container. Such motor-generator technology is well known and understood by those skilled in the art, and a detailed explanation thereof is not necessary for purposes of describing the method and system according to the present invention.
For the embodiment shown in
The
Vacuum pack (34) may be of any suitable design appropriate for sealing items including clothing items and food items. Such vacuum pack technology is well known in the art and suitable vacuum pack designs are disclosed in U.S. Pat. No. 5, 954,196 issued to Lin and U.S. Pat. No. 5,761,992 issued to Gallo and such patents are incorporated by this reference for all purposes.
Additionally, the smart container may further comprise a removable pack that is configurable as both a vacuum pack and an inflatable pack. For this embodiment of the invention, vacuum pack (34) may be configured to inflate and serve, for example, as an air pillow. Connector (35) is a reversible connector that allows air flow in only one direction, either into the removable pack or out of the removable pack, depending on the connector (35) configuration. Connector (35) of vacuum pack (34) (a removable pack) is connected to output-port (38) of vacuum pump (32) by associating one end of hose (36) to connector (35) and the opposite end of hose (36) to output-port (38) of vacuum pump (32). When activated, vacuum pump (32) becomes an air pump that inflates vacuum pack (34) into a predefined shape, such as the shape of a typical pillow. The outer surface of vacuum pack (34) may be covered with a lining comfortable to the touch.
One possible embodiment of a reversible connector (35) is a connector comprising a check valve that is housed in a detachable housing. The detachable check valve is inserted into connector (35) in a manner that allows air flow in the desired direction and blocks airflow in the opposite direction. Yet another embodiment of a removable pack that may be either inflated or vacuum sealed comprises two check valves; an input check valve (allows air in but not out) and an output check valve (allows air out but not in). One such valve would be disabled depending on the application of interest. For example, when used to vacuum seal an item inside vacuum pack (34) the input check valve would be disabled.
Power for vacuum pump (32) may be supplied from a power source integral to smart container (10). Alternatively, vacuum pump (32) may comprise a power connection for connecting vacuum pump (32) to an external power source.
Yet another embodiment of the invention is shown in
One possible power source is an energy converter associated an exterior surface of the container, such as top flap (54). For this configuration, the energy converter may be a flexible photovoltaic device comprising at least one photovoltaic cell and preferably constructed from plastics or other durable materials known in the art. The photovoltaic device may be a panel that is associated with top flap (54) or top flap (54) may be formed using photovoltaic thread. One suitable photovoltaic technology is PowerFilm® manufactured by Iowa Thin Film Technologies. The electronic attributes of electronic housing (46) will be discussed in detail later in this document.
As can be seen in
It should be appreciated that external frames (such as external frame (44)) are typically made of aluminum or other light weight materials. Such frames are substantially rigid with permanent, non-flexible attachment points. Such frames are known to work against the natural body movement of a hiker and have a tendency to tire a hiker quicker that flexible backpack designs. For one embodiment of the invention, electronic housing (46) also doubles as a flexible external frame thereby eliminating the need for external frame (44). For this embodiment, the electronic housing (46) is substantially constructed from light weight plastic materials (or other flexible or rigid materials) that provide a generally more flexible light weight designed compared to typical external frame systems. Such a frame better moves with the natural motion of the body carrying the portable system (40).
For yet another embodiment of electronic housing (46), such housing is configured to be housed inside the container (e.g. a backpack) thereby providing a flexible or rigid, comfortable internal frame design. For this configuration, the backpack may comprise ports allowing access electronic modules associated with electronic housing (46). There internal frame configuration provides added protection to the electronic housing (46) from environmental phenomenon such as rain.
Attention now is turned more particularly to the electronic attributes of the invention. Referring now to
For the purposes of this document, two items are “electrically associated” by bringing them together or into relationship with each other in any number of ways. For example, two electronic items/components may be electrically associated in numerous ways including: (a) a direct, indirect or inductive communication connection, and (b) a direct/indirect or inductive power connection. Additionally, while the drawings illustrate various components of the system connected by a single line, it will be appreciated that such lines represent one or more connections or cables as required by the smart container embodiment of interest.
Power bus (110) comprises a ground connection (or a plurality of ground connections) and at least one power connection and is configured for distributing power to electronic components of the system. Alternatively, a ground connection may be provided by a common connection such as an electrically conductive frame associated with the electronic components of the system. For the embodiment shown in
Additionally, a power module (105) may be electrically associated with a module bay. For this configuration, the power module (105) comprises a power port (106) configured for connecting to an external power source. Power module (105) may further comprise a converter (107) for converting an input voltage to a form compatible with the system components. Power module (105) may provide a single output voltage or a plurality of DC output voltages. For example, converter (107) may be configured to provide a device specific output as well as common DC output voltages including 3.3 volts, 5.0 volts, 12 volts, 24 volts, and 48 volts. Similarly, power module (105) may further comprise an inverter for generating an alternating current (AC) output voltage as well as AC output frequency. Such converter technology is well known and understood by those skilled in the art, and a detailed explanation thereof is not necessary for purposes of describing the method and system according to the present invention.
As noted above, the output of power module (105) is electrically associated with power bus (110) via power connector (109). Power connector (109) is preferably a keyed power connector comprising at least one ground connection and at least one power connector. For example, one embodiment of power bus (110) may be configured to receive six different output voltages. For this embodiment, power bus (110) comprises twelve conductors or six ground/power conductor pairs. Alternatively, fewer ground conductors may be used including a signal common ground conductor. Keyed power connector (118) is a female connector configured to receive a keyed male connector associated with an electronic module. When power bus (110) is associated with power module (105), the power module's keyed power connector (109) associates the output voltages of power module to power bus (110) in a predefined configuration. This allows an electronic module comprising an appropriately configured power connector to access the appropriated power connections when installed in a module bay.
Alternatively, converter (107) may be a programmable converter providing a range of output voltage levels. For this embodiment of the invention, the output of converter (107) is controlled by control unit (100) by issuing commands over communication bus (112). One example of such programmable converter technology is disclosed in U.S. Pat. No. 6,903,950 issued to Afzal et al. which is incorporated by this reference for all purposes.
Preferably, power module (105) further comprises power status monitor (108) configured to provide power status data. Such power status data may be provided to a display device integral to power module (105) and/or to control unit (100) via communication bus (112). Display configurations include analog visual indicators, digital numerical displays, graphic displays, and video displays.
Communication bus (112) is now considered. As described above, the smart container may comprise a plurality of electronic modules. Such electronic modules may be electrically associated with a communication bus for facilitating inter-module communication as well as communication with control unit (100) (
For the purposes of this document, a communication bus is a communication path or link that conveys information such as data, commands, and addresses, or all three in sequence or any combination thereof to a plurality of devices. The communication path may be a wired or wireless communication path comprising a plurality of wires or a single path such as a fiber optic link.
To fully leverage the capabilities of a smart container system comprising multiple electronic modules and devices, a smart container “networking” scheme is used for the preferred embodiment. As is well known, communication systems minimally require a transmitter (wired or wireless) to send information, a receiver to receive the information, and a link between the two. Communication bus (112) is such a link between the control unit (100) and one or more electronic modules (120) and is part of a “networking scheme” for networking the various electronic devices associated with the smart container
Communication bus (112) may be configured with multiple conductors such as a three conductor system comprising a ground conductor, power conductor, and data conductor over which serial communications is conducted. Similarly, communication bus (112) may comprise more advanced technologies such as a Universal Serial Bus (USB) or Ethernet. Indeed, some configurations of the invention may comprise two or more communication buses.
For the embodiment of the invention illustrated in
For the preferred embodiment, electronic modules are hot-pluggable and automatically announce their presence and capabilities to other devices and configure themselves when connected to the network saving the user from reading installation instructions and configuring network addresses and drivers.
Yet another possible communication architecture that may be used by the smart container is Home Audio Video Interoperability (HAVi) architecture using an API (Application Programming Interface). For this configuration, the communication bus (112) complies with IEEE 1394 wiring (Firewire). Such HAVi technology is disclosed in U.S. Pat. No. 6,829,656 issued to Szucs et al. which is incorporated by this reference for all purposes.

Microcontroller (210) may be further associated a mass storage device such as mass storage (244). One example of a mass storage device is a magnetic/optical hard drive. Mass storage (244) may be used to store any data but is particularly suitable for storing large data files such as image files and sound files.
The smart container may further comprise a display device electrically associated with microcontroller (210). A Liquid Crystal Display (LCD) is one possible display device that may be used for displaying information to a user. While an electronic display is preferred, mechanical displays may be used without departing from the scope of the invention. For the preferred embodiment of the invention, LCD (258) is configured for displaying information to a user. LCD (258) may be further configured with touch screen technology thereby providing a user interface by which a user can input data into the system. Alternatively, user interface (260) may be electrically associated with controller (210) and may comprise various technologies including: (a) a single button, (b) a keypad, and (c) an auditory interface such as the ones used by the permanently blind.
Control unit (100) may further comprise technology configured for wireless communications such as a receiver, a transmitter, and/or a transceiver. For the embodiment of the invention shown in
Some embodiments of a smart container may comprise a signaling device for providing a signaling function and/or an entertainment function. For this configuration, signaling device (256) is electrically associated with microcontroller (210) and comprises at least one of a light emitting element and a sound emitting element. For configurations including lights, such lights are preferably positioned around the perimeter of the smart container. For example, a user may carry a portable transmitter, such as a key chain transmitter that comprises a “lights button,” that when pressed, transmits a signal that is received by transceiver (250). Such a received signal may instruct controller (210) to activate signaling device (256) in a predefined pattern thereby making the smart container easier to locate. For the purposes of this document, a predefined pattern may be a random pattern. Similarly, in response to user input, microcontroller (210) may be further configured to use transceiver (250) to transmit a signal to the portable transmitter instructing it to activate a light associated with the key chain transmitter (or to emit a sound) to assist in locating the key chain transmitter.
Control unit (100) and/or the smart container may further comprise an integral power storage device such as power storage device (238). Power storage device (238) is electrically associated with the microcontroller (210) and/or power bus (110). One possible power storage device is a battery or an array of batteries. Preferably, power storage device (238) is a backup power source that keeps the microcontroller (210) and selected components active when power bus (110) is not associated with a power source. For the embodiment of the invention shown in
Power storage device (238) may be further electrically associated with power bus (110) through a switched connection. For such an embodiment, microcontroller (210) is electrically associated with the control input of power switch (236a). Power storage device (238) is electrically associated with one side of power switch (236a) and power bus (110) is electrically associated with the other side of power switch (236a). It will be appreciated that the electrical connections associating microcontroller (210), power storage device (238), and power bus (110) may comprise a single conductor or a plurality of conductors. Similarly, power switch (236a) represents at least one mechanical or electronic switch having a single switch with one pole, a single switch with a plurality of poles, or and plurality of switches. Additionally, power switch (236a) may be bidirectional switch or unidirectional switch or a combination of the two.
Microcontroller (210) may be further configured to monitor the status of power storage device (238) and actuate power switch (236a) when it has determined that the power storage device (238) needs recharging. Similarly, microcontroller (210) may actuate power switch (236a) so that power storage device (238) supplies power to an electronic module associated with power bus (110).
Power storage device (238) may be further associated with other electronic components integral to the container such as RAM memory (242), mass storage (244), LCD (258), and integral device (262). For this embodiment, power storage device (238) is electrically associated with selected components of the system through switch (236b) and connection (252). Microcontroller (210) is electrically associated with control input of switch (236b). Power storage device (238) is electrically associated with one side of switch (236b) and selected components of the system are electrically associated with the other side of switch (236b) through connection (252). As before, it will be appreciated that the electrical connections associating microcontroller (210), power storage device (238), and selected components of the system together may comprise a single conductor or a plurality of conductors. Similarly, switch (236b) represents at least one mechanical or electronic switch comprising a single switch with one pole, a single switch with a plurality of poles, or and plurality of switches. With this configuration, microcontroller (210) may perform numerous power functions such as a controlled shutdown. For example, when no functional power source is associated with power bus (110) and the power storage device (236b) is depleting its power, microcontroller (210) may determine that mass storage (244) and transceiver (250) are not currently required and turn off power to such systems to conserve power.
Microcontroller (210) may further be associated with a biosensor (254) configured for providing identification data used in an automated identification system. Biosensor (254) is configured for sampling various features associated with a user such as facial features, fingerprints, hand geometry, handwriting, iris, retinal, vein, and voice. For this embodiment, microcontroller (210) takes a baseline electrical interpretation of a biosample for a user attribute using biosensor (254) and stores biodata (or identification data) in a memory associated with microcontroller (210). When a user wishes to access the container or system components, the microcontroller (210) requests a bioreading from the user and compares the newly sampled biodata with the stored identification data. If the microcontroller (210) determines that the two biosamples are from the same person, the microcontroller (210) performs a desired function, such as unlocking an electronic lock associated with the smart container or releasing an electronic module.
Attention is now directed to the electronic devices that may be electrically associated with a smart container. Electronic devices may be integral components of the smart container or they may be incorporated into electronic modules configured to be received by a module bay. That being said, it should be appreciated that electronic devices described below as modules in one configuration may integrated into the smart container system as an integral device in a different configuration. Similarly, electronic devices described below as integral devices may be integrated into electronic modules. Additionally, the features of two or more modules may be incorporated into one module or integral device.
One example of an integral device is an electronic lock configured to secure the smart container. For this embodiment of the invention, microcontroller (210) controls the status of the electronic lock. Upon receiving user input from a user interface, program routine, a remote transmitter or biosensor (234), etc., microcontroller (210) changes the status of the electronic lock accordingly. For example, as noted above, a user may transmit a signal to the smart container using a portable transmitter associated with a key chain having, for example, a “light” and a “unlock” button. When the user presses the “unlock” button within range of the transceiver (250), microcontroller (210) receives the unlock signal and unlocks the electronic lock. Such electronic lock technology is well known and understood by those skilled in the art, and a detailed explanation thereof is not necessary for purposes of describing the method and system according to the present invention.
One example of program routine that instructs microcontroller (210) to cycle the electronic lock includes a program routine executed by microcontroller (210) (or other processing devices such as an ASIC, Application Specific Integrated Circuit) that monitors the smart container for movement for a predefined period of time using a motion sensor associated with the smart container. If the microcontroller (210) detects movement for ten minutes (for example) the microcontroller (210) will conclude the smart container is in transient and should be locked. Microcontroller (210) then checks the status of the electronic lock, and if it is not locked, microcontroller (210) generates a lock signal that is transferred to the electronic lock thereby locking the electronic lock and securing smart container (10).
Microcontroller (210) may be further configured to use such motion sensors for other purposes such as monitoring the portable container environment for movement. For this embodiment, microcontroller (210) is associated with a motion sensor through either a wired or wireless link. The motion sensor may be an integral electronic device or an electronic module configured with a transmitter (such as Bluetooth) that may be removed from the container and placed at a strategic location near the smart container. When the motion sensor detects motion, it generates motion-data that is transferred to microcontroller (210). In response to the motion-data, microcontroller (210) may perform any number of predefined functions including: (a) activating a signaling device, (b) activating a recording device, and (c) transmitting a data signal. The transmitted data signal may comprise any container data linked to microcontroller (210). For example, hikers may find such a configuration useful when leaving campsites and backpacks unattended while they go exploring. Such hikers would preferably carry an electronic device comprising a receiver, such as a PDA, watch, etc., that is configured to received the transmitted data-signal.
Similarly, any number of sensors may be associated with microcontroller (210) and used to monitor various attributes of the smart container. For example, a magnetic sensor (such as the well known magnetic sensors used in security systems) may be associated with the smart container that detects when the smart container is opened. Microcontroller (210) monitors the sensor and generates system-data describing, for example, when the container was opened, how long the container was opened and where it was opened (for configurations that comprise a location determination module). For configurations associated with a recording module (descried below), the microcontroller (210) may further record image data and/or sound data. Other sensors include, temperature sensors, acceleration sensors, hygrometers, altimeters, weight, light, current, voltage, magnetic field sensors, or any device that may be electrically associated with microcontroller (210) and configured to provide information about the smart container's environment.
Another integral device that may be associated with microcontroller (210) is a transmitter configured to transmit a relatively high power signal compared to transceiver (248). Preferably, such a transmitter may be used to transmit system-data to a remote receiver at least one mile from the smart container. Additionally, such a transmitter may be configured for a specific purpose such as transmitting a distress signal. One embodiment of such at transmitter comprises a device that transmits a signal at 406 MHz, a frequency monitored by Search and Rescue (SAR). The signal transmitted may be a personalized, coded signal that uniquely identifies a user and tells SAR who the user is, where the user is, and that the user is in a life-threatening situation.
Alternatively, some situations may not warrant transmitting a SOS signal. For such situations, the microcontroller may be configured to transmit a data signal to an electronic device comprising a receiver. Again using the example of a hiker exploring the area around his/her campsite, such a hiker may become lost or simply “turned around.” The hiker uses a portable electronic device comprising a transmitter (watch, PDA, celluar phone, etc.) and transmits a signal to smart container (10). In response to the received signal, microcontroller (210) may perform any number of functions including transmitting the container's location data to the hiker, transmitting a signal to a remote receiver associated with a third party or monitoring station, and activating a signaling device associated with smart container (10).
Attention now is direction to the various electronic modules that may be electrically associated with a module bay. Examples of electronic modules include: (a) a communication module, (b) a security module, (c) a recording module, (d) an entertainment module, (e) a clock module, (f) location module, (g) a display module, and (h) a power module.
It will be appreciated that any number of electronic devices may be integrated into the smart container system without departing from the scope and spirit of the invention. The electronic modules described below are presented by way of example and the smart container system may comprise a plurality of physically separated but cooperatively associated electronic devices comprising electronic components that are not shown independently such as communication interfaces, transmitters, receivers, processors, one or more display means, a magnetic card reader, bioscanner, audio speakers, sensors, and the like, each preferably communicating with or under control of the microcontroller (210) or another electronic module. As noted above, for the preferred embodiment, electronic modules are hot-pluggable and automatically announce their presence and capabilities to other system modules and integral devices and configure themselves when connected to the smart container. Additionally, module features of two or more electronic modules may be condensed into a single module without departing from the scope of the invention. For example, the features of a recording module, location module, and communication module may be comprised in a single module or even a single integral electronic device.
A communication module is a module configured for transferring data between the smart container and external electronic devices. The communication module may comprise a wired port for connecting a data cable between the smart container and an information source (such as the internet). Preferably, the communication module comprises at least one transmitter/receiver, or transceiver, based on technology such as Bluetooth, Wi-Fi, cellular phones and satellite phones. For the preferred embodiment, the communication module comprises cellular phone technology housed in typical cell phone housing (122) (block diagram representation shown in
Next one possible security module configuration is considered. The security module is configured to monitor the smart container system and/or a user associated with the smart container system. A security module may comprise any combination of features including: a sound emitter, light emitter, electronic sensors, image and sound recording devices, and a removable stun gun. The security module is electrically associated with microcontroller (210) through communication bus (112) and preferably comprises its own power source which may be electrically associated with power bus (110). The security module may further comprise a processing device that monitors at least one of (a) a user and (b) the smart container. Alternatively, the security module may simply be a signaling device that activates a strobe light and horn (for example) upon receiving an activation signal from microcontroller (210).
One possible embodiment of a recording module is now considered. The recording module comprises various technologies for recording at least one of images and sound. For the preferred embodiment, the recording module comprises a commercially available digital camcorder housed in a camcorder housing associated with a battery. The digital camcorder is received by a module housing (120) configured for releasably receiving the camcorder. The module housing is inserted into module bay (114) thereby electrically associating the camcorder with at least one of communication bus (112) and power bus (110). Typical camcorder outputs include firewire and USB. Depending on the communication bus (112) configuration and the camcorder output port configuration, the camcorder output may be directly associated with communication bus (112) or it may be electrically associated with a module communication interface which is electrically associated with communication bus (112). Preferably, the camcorder may be removed from the smart container so that a user may record images and sound as desired. Additionally, when associated with module housing (120) and installed in the smart container system, the camcorder is configured so that it may record images/sound of the smart container's environment upon receiving a record signal from microcontroller (210). The record signal may be transmitted over communication bus (112) or via a wireless signal (for Bluetooth enable camcorders). Additionally, microcontroller (210) may be configured to retrieve image and sound data from the recording module and store such data in mass storage (244) or transmit such image and sound data to a remote location.
Another embodiment of a recording module comprises a plurality of digital cameras associated with the smart container so that at least one digital camera is associated with a plurality of outside surfaces such as the top surface, the side surfaces, and the bottom surface. For the preferred embodiment of the invention, the microcontroller (210) is configurable to control the digital cameras and record images upon a local user request or a remote request such as a remote request transmitted from a distant transmitter. For one embodiment of the invention, at least one digital camera is a fully contained system comprising its own power source and is preferably releasably associated with the smart container allowing a user to remove said camera and record images as desired. When the camera module is reinserted into a module bay associated with the smart container, microcontroller (210) may be further configured to transfer recorded images from the digital camera to mass storage (244) or to transmit such images to a remote computer.
One possible embodiment of an entertainment module is now considered. The entertainment module is configured with any number of electronic devices used by people for enjoyment purposes. Typical examples of such electronic devices include MP3 players, CD players, DVD players, and gaming computers such as GameBoy®. The entertainment module may further comprise an LCD display. As described above, such devices may be HAVi enabled to facilitate inter-modular communications. For example, lights associated with a signaling device may be activated in response to music played by a CD player associated with an entertainment module.
The next module considered is a clock module. The clock module is a time keeping device configured to display the time in at least one time zone. The clock module preferably comprises its own power source which may be electrically associated with power bus (112). Additionally, the clock module may be electrically associated with microcontroller (210) through communication bus (110). The clock module may be configured to maintain an accurate time for the smart container system. One embodiment of such a clock module would comprise “Atomic clock” technology that sets/resets itself using a 60 kHz VLF radio time signal transmitted by NIST.
The clock module may further comprise alarm clock functionality to signal a user when a preset time has been reached. This feature may be particularly useful when traveling by eliminating the need for the user to learn how to operate an unfamiliar alarm clock. Additionally, the clock module may further be configured to display the time in a plurality of time zones. Such a clock module might be particularly useful when traveling to other time zones by allowing the user to maintain readouts of his home time zone and the time for a different time zone.
The next module considered is a location determination module. The location determination module is configured with electronic equipment for determining the location of the smart container. Such technology includes GPS (Global Positioning System) basted technologies as well as other technologies such as those based on cellular phone transmissions. For the preferred embodiment, an electronic module comprising a GPS receiver is electrically associated with a module bay. The GPS receiver is configured to determine the containers position and generate position-data. Such position-data is preferably available to microcontroller (210) through communication buss (110).
For still another embodiment of the invention, smart container (10) comprises a plurality of location determination devices detachably associated with the smart container. For this embodiment, a location determination device is associated with each member of a group of users. As the group explores the area around the smart container, position-data for each user is periodically transmitted to smart container (10) thereby forming a monitoring center. Microcontroller (210) is further configured to display the position-data on a display device or module associated with smart container (10). For the purposes of this document, periodically transmitting a signal means to transmit a signal at set intervals and random intervals.
The next module considered is a display module. The display module may comprise any of a number of technologies for displaying information to a user. For the preferred embodiment, the display device complies with at least one of the following criteria: small footprint, light weight, low power consumption, completely flat screen, crisp picture comprised of digital and uniform colors, and fully digital signal processing technology with low electromagnetic emissions. One possible embodiment of such a display comprises Liquid Crystal Display (LCD) technology, such as display (30) shown in
By way of example, one possible smart container system is examined to further illustrate the various aspects of one embodiment of the invention. For this embodiment of the invention, the smart container is a bag such as book bags carried by students (although such a bag may be used in any number of ways to transport items other than books). For this exemplary embodiment, the book bag comprises an electronic signaling element comprising at least one of (a) a light emitting source and (b) a sound emitting source. For example, in a child's book bag, the signaling element may be lights positioned around the perimeter of the book bag. The book bag further includes a user interface configured for receiving user input. The user interface may be a wired or wireless interface. One embodiment of a wireless user interface would be a watch configured with a transmitter. The user interface and the electronic signaling device is further associated with a processing device.
The processing device is associated with a memory and configured for controlling/monitoring the book bag components. The book bag is further configured with a motion sensor electrically associated with said processing device and configured for generating motion-data. Motion-data may be any type of data that is used by the processing device to determine when the book bag is moving. The processor is further configured to activate the electronic signaling device in response to at least one of (a) motion-data, and (b) user input. For example, the processor may be figured to monitor the book bag for motion and upon detecting motion, activating the signal device to catch the attention of the user. Alternatively, upon detecting motion, the processor may be configured to activate the signaling device in a predefined pattern (similar to lights used in children's shoes). For some embodiments, the predefined pattern may be defined by a user. Additionally, for embodiments comprising a communication port or similar communication technology described above, the predefined patterns may be shared between different book bags allowing friends to share their light patterns.
The book bag further comprises a power source electrically associated with the processing device and said signaling device. One possible power source is a magnetic device associated with a wheel (for books bag embodiments having wheels). Alternatively, the power source may be a battery or a flexible photovoltaic cell associated with the book bag.
The book bag may further comprise a receiver electrically associated with the processing device. The receiver is configured for receiving a data-signal transmitted from an electronic device. The processing device is further configured to activate the electronic signaling element in response to a received data-signal. For example, the received data-signal may be transmitted by a transmitter associated the user, such as a watch or a key chain transmitter. This feature would be useful in locating the book bag among a group of book bags or for locating a lost book bag.
The book bag may further comprise a recording device electrically associated with the processing device and configured for generating recorder-data. Exemplary embodiments of a recording device comprise at least one of (a) an image recording element and (b) a sound recording element (as described earlier in this document). The processing device is further configured to activate said recording device in response to one of (a) user input and (b) a received data-signal (a wireless communication). With such a configuration, a user can use the book bag to record a class lesson, an event at school, or an emergency situation. For example, a child is approached by a person intending to do harm to the child. The child presses a panic button, perhaps associated with the book bag or a watch transmitter (as described earlier). The processing device would immediately begin recording image and sound data and activate the signaling device.
The book bag may further comprise a transmitter electrically associated with the processing device and configured for transmitting a data-signal to a remote location. For this embodiment, the processing device is configured to activate the transmitter and transmit a data-signal in response to at least one of (a) user input, and (b) a received data-signal (as described previously). The transmitted data signal comprises one of (a) at least part of said motion-data, and (b) at least part of said recorder-data. Continuing the child adduction example described above, when the child presses the panic button, the recorder-data is immediately transmitted to a remote location such as a monitoring station and/or a parent. The transmitter may comprise cellular technology as well as other well known communication technologies.
The book bag may further comprise a flexible photovoltaic cell configured for supplying power to at least one of (a) said power source, and (b) the electronic components associated with the book bag. Such photovoltaic cell technology was described earlier.
The book bag may further comprise a transceiver electrically associated with said processing device. Suitable transceiver technologies include Bluetooth and Wi-Fi. With this technology, a student can listen to (and share with other students) music played by an electronic device associated with the processing device. Students may talk among themselves using Bluetooth enabled headsets. More importantly, a student could better listen to a class lecture given in a large lecture hall where the speaker's voice is transmitted by a Bluetooth transmitter.
Some embodiments of the book bag further comprise at least one module bay configured for receiving an electronic module such as the electronic modules described earlier. A communication bus is electrically associated with at least one module bay and the processing device. A power bus electrically associated with said at least one module bay and said processing device.
Another embodiment of the book bag comprises a frame associated with the container. A first wheel is positioned at a first location on the frame and a second wheel positioned at a second location on said frame. An extendable handle is associated with the frame and configured to adjustably extend from the frame to a position that allows a user to rest the container on said first wheel and said second wheel when moving the container. A magnetic device is associated with at least one wheel and is configured for generating power when the wheel is rotating. Alternatively, a magnetic device configured for generating an oscillating magnetic field may be associated with the smart container. One embodiment of a magnetic device configured for generating an oscillating magnetic field is a magnet associated with a rod and configured to slide back and forth across the rod when the smart container is moved. A coil of wire surrounds the rod so that the oscillating magnetic flux lines induce a current in said coil. The output of the magnet device is electrically associated with at least one of (a) said power bus, (b) said signaling device, (c) said power source, and (d) said controller.
Attention is now directed to methods for monitoring a container used for transporting items while traveling. For one preferred method, the first step is to associate a controller with the container. As before, the controller may comprise any number of electronic devices and is associated with a memory. Additionally, the controller is electrically associated with at least one electronic module and a power source.
As noted above, the electronic module may comprise any number of electronic devices including communication modules, location determination modules, entertainment modules, and security modules. For one embodiment of the present method, the electronic module is configured to monitor a container-parameter and generate a data-signal relating to said predefined parameter. A container-parameter is simply any environmental or container attribute that is quantifiable by an electronic data-signal. Examples of container-parameters include temperature, location information, pressure, acceleration, light, motion, images, sound, electromagnetic waves, voltage, current, and power.
The controller is configured to perform any number of predefined functions in response to said data-signal. For example, upon detecting motion, the controller may activate a signaling device, transmit a signal to a remote electronic device, or verify that an electronic lock is locked (and if not, initiate a lock signal).
