The present disclosure relates generally to an arrangement for, and a method of, finding and recovering an electrically-powered, mobile device, such as a portable data capture device, that is missing and presumed to be lost in a venue, such as a retail store.
Many different types of electrically-powered, mobile devices, such as handheld data capture readers, smartphones, tablets, computers, smartwatches, or like electronic devices, are held or worn, and operated, by human operators in various venues, such as retail stores, factories, warehouses, distribution centers, buildings, or like controlled indoor and outdoor areas. For example, one type of mobile data capture device can be a handheld, radio frequency (RF) identification (RFID) tag reader for reading RFID tags associated with products located in the venue. Another type of mobile data capture device can be a handheld, bar code symbol reader, either moving laser beam-based or imager-based, for electro-optically reading bar code symbols associated with the products. Still another type of mobile data capture device can be a handheld terminal or computer, such as a smartphone with an onboard camera for capturing images of various targets, such as bar code symbols, products, or operators. In operation, such electronic mobile devices are electrically powered by an onboard battery, and are operated to perform their data capture functions, typically while being held in one of the operator's hands.
Although such mobile devices are generally satisfactory for their intended purposes, the operators may, from time to time, lay their mobile devices down on a nearby support surface to take a break, or to free their hands to perform tasks other than data capture, such as retrieving products from storage, or attending to some paperwork, etc., and thereafter, may forget to pick their mobile devices up to resume their operation, or forget where they laid the mobile devices down. Time and labor must be expended to hunt down these missing mobile devices. Sometimes, these missing mobile devices are never found and are deemed lost. Such lost mobile devices are costly to replace, and are unavailable to perform their intended functions.
Accordingly, it would be desirable to readily find and recover such lost mobile devices so that they need not be replaced and can be readily put back into service, with minimal service disruption.
The accompanying figures, where like reference numerals refer to identical or functionally similar elements throughout the separate views, together with the detailed description below, are incorporated in and form part of the specification, and serve to further illustrate embodiments of concepts that include the claimed invention, and explain various principles and advantages of those embodiments.
Skilled artisans will appreciate that elements in the figures are illustrated for simplicity and clarity and have not necessarily been drawn to scale. For example, the dimensions and locations of some of the elements in the figures may be exaggerated relative to other elements to help to improve understanding of embodiments of the present invention.
The arrangement and method components have been represented where appropriate by conventional symbols in the drawings, showing only those specific details that are pertinent to understanding the embodiments of the present invention so as not to obscure the disclosure with details that will be readily apparent to those of ordinary skill in the art having the benefit of the description herein.
One aspect of this disclosure relates to an arrangement for finding and recovering an electrically-powered, mobile device that is missing and presumed to be lost in a venue. The mobile device can be any handheld data capture reader, smartphone, tablet, computer, smartwatch, or like electronic device. The venue can be any environment, such as a retail store, a factory, a warehouse, a distribution center, a building, or a like indoor or outdoor controlled area. The arrangement includes a sensing system for generating sensing signals, each indicative of motion and/or location of the mobile device in the venue. A control system is operatively connected to the sensing system for executing a recovery action indicative of at least one location of the mobile device in response to at least one of the sensing signals. An interface is operatively connected to the control system for indicating the at least one location of the mobile device.
In one embodiment, the sensing system may include a motion sensor, such as an accelerometer, supported by the mobile device and operative to determine when the mobile device is in motion, and when the mobile device is at rest. In another embodiment, the sensing system may include a locationing system deployed in the venue and also operative to determine when the mobile device is in motion, and when the mobile device is at rest. The locationing system may advantageously be an ultrasonic locationing system having a plurality of ultrasonic transmitters mounted in the venue remotely from the mobile device for transmitting a plurality of ultrasonic ranging signals, and an ultrasonic receiver supported by the mobile device for receiving the ultrasonic ranging signals, in which case, the control system determines that the mobile device is in motion when the received ultrasonic ranging signals are different, and that the mobile device is at rest when the received ultrasonic ranging signals are substantially the same. The locationing system may also advantageously be a video system having a venue camera mounted in the venue remotely from the mobile device for capturing images of the mobile device, in which case, the control system determines that the mobile device is in motion when the captured images are different, and that the mobile device is at rest when the captured images are substantially the same.
In one embodiment, the control system executes the recovery action by energizing a device camera on the mobile device to capture an image indicative of the at least one location of the mobile device when the at least one sensing signal indicates that the mobile device is at rest. In another embodiment, the control system executes the recovery action by energizing the device camera to capture a plurality of images indicative of a plurality of locations of the mobile device, in which case, a last one of the images is indicative of the at least one location of the mobile device when the at least one sensing signal indicates that the mobile device is at rest. In still another embodiment, the control system executes the recovery action by energizing a radio frequency (RF) identification (RFID) tag locationing system deployed in the venue for reading RFID tags associated with products located at product locations in the venue, and for finding the product locations in the vicinity of the at least one location of the mobile device when the at least one sensing signal indicates that the mobile device is at rest. In an additional embodiment, a plurality of access points is deployed in the venue, and the control system executes the recovery action by sending an identification signal of an access point to which the mobile device was connected at the at least one location of the mobile device when the at least one sensing signal indicates that the mobile device is at rest. Advantageously, a database is operatively connected to the control system for storing the at least one location of the mobile device. The interface is operative for accessing the database, for displaying the stored at least one location of the mobile device, and/or for causing a sound to be emitted from the mobile device.
Another aspect of this disclosure relates to a method of finding and recovering an electrically-powered, mobile device that is missing in a venue. The method is performed by generating sensing signals each indicative of at least one of motion and location of the mobile device in the venue, by executing a recovery action indicative of at least one location of the mobile device in response to at least one of the sensing signals, and by indicating the at least one location of the mobile device at an interface.
In accordance with this disclosure, at least one location, and preferably the last known location, of the mobile device can be readily found by consulting the interface, preferably a web page. A retail store manager, the operator, or a like person, can access the database via the interface, which is preferably a display screen. The mobile device need not be replaced and can readily be put back into service, with minimal service disruption.
Turning now to the drawings, reference numeral 10 in
As described below, a plurality of sensing network units 30 is mounted overhead, for example, on or below a ceiling 14. Advantageously, the sensing network units 30 can be installed and spaced apart every twenty to eighty feet or so in a grid in the venue 10. As depicted in
As best seen in
The block diagram of
Another sensing system is an ultrasonic locationing system operative for locating the mobile device 22. For example, the ultrasonic locationing system includes an ultrasonic locationing module 36 having control and processing electronics operatively connected to a plurality of ultrasonic transmitters, such as voice coil or piezoelectric speakers 38, for transmitting ultrasonic energy to an ultrasonic receiver or microphone 48 (see
Still another sensing system is a video locationing system operative for locating the mobile device 22, and/or the operator 24 operating the mobile device 22, and/or the product 12. The video locationing system includes a video module 40 having camera control and processing electronics that is connected to a venue camera 42 for capturing an image of the mobile device 22, and/or the operator 24, and/or the product 12. The venue camera 42 is advantageously a high-bandwidth, moving picture expert group (MPEG) compression camera. The capture of the image at the venue camera 42 is processed by the server 16 to locate the mobile device 22, and/or the user 24, and/or the product 12.
It will be understood that each sensing network unit 30 need not have all or some of the above-described locationing systems, and may include additional locationing systems, such as Wi-Fi or Bluetooth® locationing systems. In some embodiments, only one locationing system would suffice. In other embodiments, two or more of the locationing systems can cooperate with each other. In a preferred embodiment, the RFID locationing system is employed to sense the general location of the mobile device 22, and the ultrasonic locationing system and/or the video locationing system is employed to more accurately locate the mobile device 22. In addition, each sensing network unit 30 may have an access point 64 that can transmit and receive Wi-Fi communications signals via a Wi-Fi antenna 66 to an RF receiver, such as the receiver 46, on the mobile device 22. The access points are all interconnected in a wireless local area network (WLAN).
As further shown in
As previously mentioned, the operator 24 may, from time to time, lay the mobile device 22 down on a nearby or convenient support surface, such as a table 26 (see
In accordance with this disclosure, an arrangement is provided for finding and recovering the mobile device 22, whether it is lost either in an indoor venue or in an outdoor venue. The arrangement includes a sensing system for generating sensing signals that are indicative of whether the mobile device 22 is in motion or at rest in the venue 10, and a control system, e.g., the device controller 52 and/or the server controller 60, that is operatively connected to the sensing system for executing a recovery action indicative of at least one location of the mobile device 22 in response to at least one of the sensing signals. As described below, the interface 70 is operatively connected to the host server 16 for indicating the at least one location of the mobile device 22.
More particularly, the sensing system may include a motion sensor, such as an accelerometer 50 (see
The sensing system may include one or more of the aforementioned locationing systems that are deployed in the venue 10. For example, the device controller 52 and/or the server controller 60 analyze the ultrasonic ranging signals received from the microphone 48 and determine that the mobile device 22 is at rest when these received ultrasonic ranging signals are substantially the same. Otherwise, if the received ultrasonic ranging signals are different, then the mobile device 22 is in motion. As another example, the device controller 52 and/or the server controller 60 analyze the images captured by the venue camera 42 and determine that the mobile device 22 is at rest when these captured images are substantially the same. Otherwise, if these captured images are different, then the mobile device 22 is in motion. As yet another example, the device controller 52 and/or the server controller 60 analyze location signals received from the locationing receiver 46 and determine that the mobile device 22 is at rest when these received location signals are substantially the same. Otherwise, if these location signals are different, then the mobile device 22 is in motion.
As previously mentioned, the control system executes one or more recovery actions each indicative of at least one location of the mobile device 22. For example, a device camera 74 (see
As another example, the control system may execute a recovery action by energizing the RFID locationing system when the mobile device 22 stops moving. The RFID locationing system will read any RFID tags that are in the vicinity of the last known location of the lost mobile device 22. The RFID locationing system has a map of all product areas in the venue 10. By reading the RFID tags when the mobile device 22 stopped moving, the locations of the RFID tags in at least one of the mapped product areas will become known, and the location of the mapped product area is an indicator of the last known location of the lost mobile device 22. The control system will send the locations of the RFID tags to the host server 16 for storage in the database 62 and/or for display on the display 72. For example, if all the RFID tags that are read are associated with apparel or clothing products, then the lost mobile device 22 is probably in an apparel product area of the venue 10. Thus, as shown on the web page display 72 of
As another example, the control system may execute a recovery action by sending an identification signal of the access point 64 to which the lost mobile device 22 was connected at the last known location of the lost mobile device 22. The identification signal can advantageously be a media access control (MAC) address of the access point 64. The control system will send the MAC address to the host server 16 for storage in the database 62 and/or for display on the display 72. The MAC address is an indicator of the location of the connected access point 64 and, in turn, of the last known location of the mobile device 22.
The interface 70 can access the server memory 58 and/or the database 62 to retrieve the last known location of the mobile device 22. This retrieval is immediate and, therefore, the last known location of the mobile device 22 is immediately available to any human operator that views and operates the interface 70. Preferably, the control system will keep a historical log of all past locations of the mobile device, since some employees may habitually lose their mobile devices 22 in the same location. The control system may also keep a running log of several known locations of a mobile device in case the last known location is not ideal. The interface 70 can display the last known location of the mobile device 22 even when the battery 44 fails. The keyboard 68 can also be operated to cause an audible sound to be emitted from a beeper 76 (see

In the foregoing specification, specific embodiments have been described. However, one of ordinary skill in the art appreciates that various modifications and changes can be made without departing from the scope of the invention as set forth in the claims below. Accordingly, the specification and figures are to be regarded in an illustrative rather than a restrictive sense, and all such modifications are intended to be included within the scope of present teachings.
The benefits, advantages, solutions to problems, and any element(s) that may cause any benefit, advantage, or solution to occur or become more pronounced are not to be construed as a critical, required, or essential features or elements of any or all the claims. The invention is defined solely by the appended claims including any amendments made during the pendency of this application and all equivalents of those claims as issued.
Moreover in this document, relational terms such as first and second, top and bottom, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. The terms “comprises,” “comprising,” “has,” “having,” “includes,” “including,” “contains,” “containing,” or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises, has, includes, contains a list of elements does not include only those elements, but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. An element proceeded by “comprises . . . a,” “has . . . a,” “includes . . . a,” or “contains . . . a,” does not, without more constraints, preclude the existence of additional identical elements in the process, method, article, or apparatus that comprises, has, includes, or contains the element. The terms “a” and “an” are defined as one or more unless explicitly stated otherwise herein. The terms “substantially,” “essentially,” “approximately,” “about,” or any other version thereof, are defined as being close to as understood by one of ordinary skill in the art, and in one non-limiting embodiment the term is defined to be within 10%, in another embodiment within 5%, in another embodiment within 1%, and in another embodiment within 0.5%. The term “coupled” as used herein is defined as connected, although not necessarily directly and not necessarily mechanically. A device or structure that is “configured” in a certain way is configured in at least that way, but may also be configured in ways that are not listed.
It will be appreciated that some embodiments may be comprised of one or more generic or specialized processors (or “processing devices”) such as microprocessors, digital signal processors, customized processors, and field programmable gate arrays (FPGAs), and unique stored program instructions (including both software and firmware) that control the one or more processors to implement, in conjunction with certain non-processor circuits, some, most, or all of the functions of the method and/or apparatus described herein. Alternatively, some or all functions could be implemented by a state machine that has no stored program instructions, or in one or more application specific integrated circuits (ASICs), in which each function or some combinations of certain of the functions are implemented as custom logic. Of course, a combination of the two approaches could be used.
