In addition, this patent application hereby incorporates U.S. Patent Application No. 62/145,249 by reference in its entirety for all purposes, and is to be interpreted consistent with this patent application. Moreover, any embodiments, variations, and other disclosures contained within U.S. Patent Application No. 62/145,249 that are not reflected in this patent are intended to be viewed as alternative/additional embodiments, variations, etc. However, if there are any irreconcilable conflicts between the disclosures of this patent application and the disclosures of U.S. Patent Application No. 62/145,249, then this patent application's disclosures on such issues shall be controlling for interpreting patent Claims.


BACKGROUND
The nearly constant use of myriad mobile electronic devices by consumers has long been ubiquitous in society, causing requiring many, if not most, consumers to seek means to be able to recharge and/or increase their mobile charge capacity for their mobile devices while away from their usual outlet-supplied chargers at home or office. The market for portable powerbanks has grown rapidly, as the cost and size has gone down. This in turn has led to a promotional-product opportunity.
However, by itself, a portable powerbank provides very limited effectiveness as a brand-promotion tool in terms of longevity and frequency of instilling brand impressions. If, for example, target consumers are given a small powerbank device that has a brand statically incorporated on the packaging and/or the device itself, many, if not most, of those consumers quickly forget about the source of the powerbank device (despite the static branding on the device) and merely concentrate on the charging utility of the device for their mobile devices.
What is needed is an improved portable powerbank device with enhanced capabilities to instill long-lasting and/or repeated brand impressions on a user.
BRIEF SUMMARY
The inventive disclosures contained herein are generally directed to an improved portable powerbank (or battery bank) that is integrated with video storage and playback/display capabilities for use as a promotional product and/or related services. This integration of the additional media-play capability and related additional functionality represents a major step apart from existing powerbanks, including the many versions of powerbanks used in the promotions industry. Effectively, the improved device is an electronic billboard and/or video player that can keep a user engaged because of a user's motivation to use the powerbank functionality. The improved device is sometimes herein referred to as a “Video-In-Powerbank” (“VIP”) or as a “Billboard-In-Powerbank” (“BIP”), or both (“VIP/BIP”), and each use of any of these terms should be construed as including the others, though for simplicity, “VIP” is generally a preferred term.
The combination of the improved powerbank's high user utility with the integrated video/audio player's strong capability in communicating promotional messages, the VIP significantly elevates the promotional effectiveness of each VIP device, as compared with the individual parts of the sum.
In most embodiments, the VIP incorporates control logic that implements one or more strategic algorithms that are designed to enable or disable certain functional capabilities of the VIP in order to encourage end-users to actually watch/listen to promotional video and/or audio media for a predetermined minimum number of VIP operational cycles, which are tracked internally, before releasing certain functional capabilities for end-user use in order to help promotions companies and/or their clients ensure that a VIP given out to end-users is providing a requisite amount of commercial exposure to whatever promotional messages are intended to be communicated to end-users.
Some embodiments have other enhancements, including an incorporated count-down-timer function that is super-imposed on the displayed video images, which in turn can be used for event count-down or other functions that require the use of time-tracking.
The foregoing Brief Summary is intended to merely provide a short, general overview of the inventive disclosure described throughout this patent application, and therefore, is not intended to limit the scope of the inventive disclosure contained throughout the balance of this patent application, including the appended Claims and Drawings.

III. An Improved Portable Powerbank with Integrated Promotional-Media-Play Capabilities
This Section III is generally directed to an improved portable powerbank (or battery bank) that is integrated with video storage and playback/display capabilities for use as a promotional product and/or related services. Effectively, the improved device is an electronic billboard and/or video player that can keep a user engaged because of a user's motivation to use the powerbank functionality. For simplicity, the improved device is sometimes herein referred to as a “Video-In-Powerbank” (“VIP”) or as a “Billboard-In-Powerbank” (“BIP”), or both (“VIP/BIP”). Refer to FIGS. 1A through 1I, 2, 4A, 4B-1 through 4B-8, and 4C-1 through 4C-5, which depict an embodiment of the VIP 13 structural-implementation details and an embodiment of the relationship between a VIP 13 and a host network 15, 16, 17, 18 and end-user mobile-computing device 14.
The combined aforementioned utilities of the VIP 13 provides a convenient vehicle for encouraging end-users to view communicated promotional messages in exchange for the use of the VIP's 13 charging capability, as well as any post-promotional message video and/or audio media play (i.e., entertainment media play) in some embodiments.
In an embodiment, the VIP 13 typically is fabricated in a substantially rounded-rectangular form factor, wherein the casing 2, 8, 12 is largely comprised of aluminum, aluminum alloy, hard plastic, or other suitable light-weight and strong materials. On the top surface 2, various controls and displays are provided, such as a display window 11 (typically an LCD display), at least one speaker 5, 5A, 5B, and three control buttons 1A, 1B, 1C. One control button 1C allows a user to power ON or power OFF the VIP 13. Another control button 1B allows a user to control the pausing and navigation through media being played, though in most embodiment, this functionality is strategically limited to the standard functions of PLAY, PAUSE, and FAST-FORWARD (that is, there is no REWIND functionality). The third control button 1A provides a means for a user to MUTE the VIP's 13 sound and/or adjust the volume of the media play. Finally, in some variations, an additional LCD or LED display 4A is provided to display to an end-user how many usage cycles the VIP 13 has been through since the last resetting of its “Activation Count” registry within the onboard memory 6.
In variations of the VIP 13, a plurality of USB ports 6A, 6B, 6C are disposed within a display lens 7. In many embodiments, two of the USB ports 6A, 6C are Type-A USB ports, at least one of which supports both power and data transmission, and have output current ratings of at least 1.0 ADC to 2.0 ADC, typically at a voltage in the range of 3.7 VDC to 5.0 VDC to support most smart electronic devices to be charged. In addition, the third USB port 6B is commonly a “mini-USB” port (often a “mini-B” USB port) is adapted to allow the charging of the VIP 13 from an external source.
Internally, in many embodiments, the VIP 13 is additionally comprised of a light-weight inner frame, typically comprised of a sturdy, but inexpensive plastic, though other materials can be used, and a plurality of fasteners 3 (typically threaded fasteners, but not limited to such) to hold the various enclosure components 2, 4, 7, 8, 9, 11, 12 together. In most variations, the VIP 13 further comprises one or more rechargeable batteries 10, typically lithium-polymer or lithium-ion batteries, though other existing or emergent battery technologies can be used. Because of the likelihood that in many applications the VIP 13 will need to facilitate the recharging of several, if not many, mobile-electronic devices 14 between recharges of the VIP 13, a relatively high capacity for the one or more rechargeable batteries is preferred. For example, a 5000 mAH powerbank in new condition, and depending on factors such as ambient temperature, can probably support the fully recharging of a battery-depleted iPhone 6® at least two times, perhaps a bit more. In preferred embodiments, the VIP's 13 batteries 10 will be rated at least for 10,000 mAH to support the recharging of four to five smartphones between full recharging of the VIP 13. In situations where a high level of relatively quick reuse of a VIP 13 is anticipated; e.g., a restaurant owning a plurality of VIP 13 devices equipped with pager capabilities for use in managing table-wait queues might need each VIP 13 to have a minimum charging-output capacity of at least 20,000 mAH—in addition to the power required to operate the VIP's 13 other functionalities, such as media play, since the restaurant's VIPs 13 will likely be used by many customers in a day to charge their respective mobile-electronic devices 14 that are in various initial states of charge and such VIPs 13 may not get recharged until after the close of business for each day.
In standard embodiments, the control center of the VIP 13 is disposed on at least one printed circuit board 6, on which all of the control-logic components to manage on-board volatile and non-volatile memory, WiFi and/or USB-cable connectivity, media-file download/upload capabilities, the displays and speakers, charge and discharge states, and the like. FIGS. 4A, 4B-1 through 4B-8, and 4C-1 through 4C-5 provide one embodiment of a typical physical component layout of components on the printed circuit board 6, as well as some typical control-logic circuitry, respectively.
The printed circuit board 6 features onboard programmable logic components, such as a microcontroller or Field-Programmable Gate Arrays (FPGA), though those skilled in the art would immediately appreciate that numerous alternative control-logic-implementation devices known in the art can also be used; e.g., Application-Specific Integrated Circuits (APIC), etc. Such programmable logic components are essential for the VIP 13 to be able to perform certain key functionalities that are discussed later in this Specification, and, in many embodiments, are reprogrammable.
In some embodiments, the VIP 13 is adapted to communicate with a network via WiFi, which enables the VIP 13 to be used in a variety of ways by a user. For example, a WiFi connection for the VIP 13 better facilitates the ability for a promotions company that is giving out or lending VIPs 13 to provide on-the-fly customization of promotional video and/or audio from its network 15, 16, 17, 18, which is typically comprised of a plurality of servers, including a media server 17 and a database server 18. Further, such wireless connectivity for VIP devices 13 enable the gathering of usage data, which can be useful in adjusting the end-user experience, depending on a variety factors such as the number of VIP-activity sessions, length of usage, location data, and the current date and time.
In still more embodiments, when the VIP 13 is connected to an end-user mobile-computing device 14 such as a smartphone or tablet computer via a USB cable connected to one of the Type-A USB ports that support data communications 6C, the end-user will be prompted to provide permission on his or her device to allow the VIP 13 access to the files of the end-user's mobile device 14 in order for the VIP 13 to play media files that are resident on the end-user's mobile device 14 and/or allow the streaming of media from the end-user's mobile device 14 onto the VIP 13. In some variations, this “Multimedia-Management” functionality is only enabled within the VIP 13 after the VIP 13 has been used/activated to play its promotional materials at least a predetermined number of times in order to help motivate the end-user to watch/listen to the promotional messages enough times to meet the promotional goals of the company providing the VIP 13.
In even more embodiments, the VIP's 13 “on-module” controls 1A, 1B, 1C provide for audio volume and mute control—allowing users to adjust for the amount of “promotional presence” when the VIP 13 is in use. In variations, the Mute functionality is only enabled after the VIP 13 has been used/activated to play its promotional materials at least a predetermined number of times before allowing an end-user in order to help motivate the end-user to watch/listen to the promotional messages enough times to meet the promotional goals of the company providing the VIP 13. In some cases, the Mute functionality is merely enabled when the minimum number of VIP 13 competed play cycles have occurred in order to allow an end-user to employ the MUTE button 1A. In other cases, after the minimum number of VIP 13 competed play cycles have occurred, the Mute functionality is both enabled and automatically employed upon the startup of the VIP 13.
Additional variations include an incorporated count-down-timer function that is super-imposed on the displayed video images, which in turn can be used for event count-down or other functions that require the use of time-tracking.
IV. Detailed Functional Operations of an Improved Portable Powerbank with Integrated Promotional-Media-Play Capabilities
This Section IV is generally directed to several embedded functional processes within various embodiments of an improved portable powerbank (or battery bank) that is integrated with video storage and playback/display capabilities for use as a promotional product and/or related services. Refer to FIGS. 3A through 3I, as well as FIGS. 1A through 1I, 2, 4A, 4B-1 through 4B-8, and 4C-1 through 4C-5.
In some embodiments, the VIP 13 incorporates an automatic update/refresh of the media-playback content through the wireless connectivity (WiFi) of a host mobile-electronic device 14 (e.g., smartphone, tablet computer, etc.) as it is being charged. In variations, the VIP 13 can provide proximity-based and/or location-based playback content as the mobile-electronic device 14 is being serviced by the charger portion of the VIP 13. Moreover, still more variations facilitate the provision of time-based content; for example, a “reminder message” after one year of use to refresh customer-vendor engagement relationship.
Some enhancements also allow for the qualification of additional promotional items after certain usage thresholds; for example, by the frequency or total number of VIP 13 charges/charge cycles or by the total number of ampere-hours of charge/electrical energy used, as recorded into a VIP's 13 non-volatile memory 6. In turn, this encourages utilization of the VIP 13, which promotes brand promotion and transfer. In additional embodiments, the wireless functionality of a host mobile-electronic device 14 being serviced by the charger portion of the VIP 13 is leveraged by the VIP 13 for communications with the Internet and/or back-end servers 15, 16, 17, 18.
In some variations, the VIP 13 allows users to add the users' own content and/or other customization features after a certain time and/or frequency of use, as a consumer incentive/reward for watching and/or listening to promotional video/content while using the charging utility of the VIP 13. In related embodiments, the VIP 13 provides a user the capability of launching web-based applications (such as social media or content playback) on the mobile-electronic device being serviced by the charger portion of the VIP 13.
In even more embodiments, the VIP 13 incorporates time-based and/or remote configurable enable/disable functions in order to discourage users from “walking away” with the VIP 13 device. In other variations, the VIP 13 further incorporates a wireless pager capability, which is particularly useful for businesses that may want to hand out VIPs 13 to customers who are in a wait queue for services or products, and the VIP 13 notifies the customer by way of an incorporated vibration member (not shown) and/or other audio/visual indications that the customer's wait time is over; e.g., a restaurant's customers waiting to be seated.
Referring specifically to FIG. 3A, in one embodiment, the VIP 13 has an ON/OFF switch/button 1C, which when engaged by an end-user 21 to turn the VIP 13 ON, enables the powerbank functions 22; that is, the charge and discharge level indicator and management 4, 4A. At the same time, the ON/OFF switch/button 1C enables the video/audio-control functions 25 (e.g., volume/mute controls, fast-forward/rewind, etc.), then initiates the promotional-video/audio sequence 24. In variations, if enabled, the countdown function 27 is enabled. Finally, in some embodiments, at the end of the video sequence 28, the video/audio-control functions 25 are disabled, and the end-user can continue to use the VIP 13 to supply/recharge their connected mobile electronic devices 14.
In more variations, this startup functionality depicted in FIG. 3A also includes the calling of additional startup routines 26 for enabling one or more functionalities that are dependent on ensuring that a predetermined minimum number of promotional media plays on the VIP 13 are first completed, as tracked by the onboard Actvation Count stored in the VIP's 13 onboard non-volatile memory 6. Refer specifically to FIG. 3B, which depicts the process to enable three such functionalities. In an embodiment, upon startup, the Activation Count is first incremented and stored in the onboard non-volatile memory 30. This is then followed by a comparison 31 of the stored Activation Count with the stored reference values for:

    
    
        a light-sensing-based AUTO-RUN function 33 for the VIP 13 in which the VIP 13 can be caused to automatically startup as soon as it is removed from its packaging and senses the ambient light;
        a Mute Default function that allows the VIP 13 to startup in a mode that mutes the initial promotional media play; and
        an Open-Multimedia Manager function to allow the VIP 13 to mount to a connected host computing device 14 via either USB or WiFi.
    
    


For the light-sensing-based AUTO-RUN function comparison 33, if the Activation Count is greater than or equal to a predetermined stored reference value, then the AUTO-RUN function will be disabled 33B, as the VIP 13 has been operated enough times to exhibit/play the promotional media to meet the predetermined requirements of the promotions company that provided the VIP 13. Otherwise, if the Activation Count is less than the predetermined stored reference value, and if the light sensor 1C-1 of the VIP 13, if so equipped, detects enough ambient light 33C, then the VIP multimedia sequence will be allowed to automatically start 33A.
For the Mute Default function comparison 34, if the Activation Count is greater than or equal to a predetermined stored reference value, then the Multimedia function of the VIP 13 will be allowed to start up with the sound muted 34B. Otherwise, if the Activation Count is less than the predetermined stored reference value, then the Multimedia function of the VIP 13 will be allowed to start up with the audio ON (that is, not muted) 34A.
For the Open-Multimedia Manager function, comparison 35, if the Activation Count is greater than or equal to a predetermined stored reference value, then the VIP 13 will be allowed to mount as a storage device when connected to a host computing device 14, via either USB or WiFi 35B. Otherwise, if the Activation Count is less than the predetermined stored reference value, then the Open-Multimedia Manager function will not be enabled, and the VIP 13 will remain “invisible” to a host computing device when connected 35A.
Notably, a person ordinarily skilled in the art will appreciate that other embodiments could use all or some of the three enabling subprocesses 33, 34, 35 depicted in FIG. 3B, and that such subprocesses need not be performed in the order shown in FIG. 3B.
V. Example Methods of Use for an Improved Portable Powerbank with Integrated Promotional-Media-Play Capabilities
This Section V is generally directed to some methods of use of an improved portable powerbank (or battery bank) that is integrated with video storage and playback/display capabilities for use as a promotional product and/or related services, as described in Sections III and IV, supra. Refer to FIGS. 3A through 3I, as well as FIGS. 1A through 1I, 2, 4A, 4B-1 through 4B-8, and 4C-1 through 4C-5.
In one embodiment, the VIP 13 is combined with wireless pager-type functionality such that it is ideal for use in a setting where customers are subjected to significant wait/stationary time. In such a setting, customers often spend the wait time using their respective mobile devices 14 for myriad purposes and depleting the mobile-device 14 charge in the process. In a method of use, such a customer could be provided a pager-enabled VIP 13 such that the customer can employ the VIP's 13 charging feature for his or her mobile-electronic device 14 while being exposed to one or more promotional videos or other promotional content. Examples of venues that could benefit from this functionality include restaurants, airports, amusement parks, sports events, doctor's offices, trips on transportation vehicles, etc. A WiFi-enabled/pager-enabled VIP 13 can be used as an “on-spot” promotional item and pager in any situation that involves wait/stationary time commensurate with a meaningful charging service for a mobile-electronic device 14 (such as a smartphone or tablet computer); e.g., use by restaurants, airports, amusement parks, sporting events, medical-provider offices, transportation-vehicle vendors/service providers, etc.
In another method of use, the VIP 13 can be adapted to electronically provide a “courtesy coupon” whose value is proportional to the wait time endured by the customer/user, which is stored in memory 6, redeemable at the end of the waiting/charging period pursuant to predetermined rules governing a business' electronic-coupon program. Such coupon functionality could also be used to promote add-on sales/up-sells/cross-sells of other goods and/or services. This in turn could enhance customers' perceived goodwill of the company being promoted, as consumers are “rewarded” for their wait; it may even make waiting desirable or at least more tolerable.
