Methods and systems for smart handling of warehouse items

## Abstract

Methods and systems for smart handling of warehouse items. An embodiment takes the form of a wearable accessory that is configured to (a) identify an object, (b) detect an attachment-triggering event, (c) responsive to detecting the attachment-triggering event, attach to the object, (d) determine at least one handling constraint associated with the object, where the at least one handling constraint includes an acceptable pressure range, (e) measure a pressure exerted on the object via the accessory, (f) provide an indication, via a user interface, based on the measured pressure and the acceptable pressure range; and (g) detect a release-triggering event, and responsively release the object.

## Background
BACKGROUND OF THE INVENTION
Proper handling of warehouse items involves diverse operations that are vital to industry. These operations include, amongst other things, identifying items, manually carrying items to predetermined locations, and storing items at those respective locations. These operations (and others) provide for a continuous flow of items through the warehouse and ensure that items are available when needed. Improper handling of warehouse items, on the other hand, can negatively impact the continuous flow of items through the warehouse and may result in increased costs.
There are many factors that contribute to the improper handling of warehouse items. One factor is user notification of the item's physical nature. There is no process in place to indicate to a user that an item should be handled safely based on the physical nature of that item. The item may be brittle, fragile, or contain a liquid substance, among numerous other possibilities. While the physical nature of an item can be alerted with a warning sign, such warning signs can sometimes be overlooked by the user.
Accordingly, there is a need for methods and systems for smart handling of warehouse items.

Moreover, any of the variations and permutations described herein can be implemented with respect to any embodiments, including with respect to any method embodiments and with respect to any system embodiments. Furthermore, this flexibility and cross-applicability of embodiments is present in spite of the use of slightly different language (e.g., process, method, steps, functions, set of functions, and the like) to describe and or characterize such embodiments.
Before proceeding with this detailed description, it is noted that the entities, connections, arrangements, and the like that are depicted in—and described in connection with—the various figures are presented by way of example and not by way of limitation. As such, any and all statements or other indications as to what a particular figure “depicts,” what a particular element or entity in a particular figure “is” or “has,” and any and all similar statements—that may in isolation and out of context be read as absolute and therefore limiting—can only properly be read as being constructively preceded by a clause such as “In at least one embodiment, . . . .” And it is for reasons akin to brevity and clarity of presentation that this implied leading clause is not repeated ad nauseam in this detailed description.
FIG. 1 depicts several views of a first example pressure-sensing glove, in accordance with some embodiments. In particular, FIG. 1 depicts an example pressure-sensing glove 102 and an object 112 (e.g., a box or other package). The pressure-sensing glove 102 has a scanner 104, an RFID reader 106, and an NFC reader 108. The object 112 has an indicia 110 (e.g., a bar code).
The scanner 104 can be affixed to any portion of the pressure-sensing glove 102. The scanner 104 can also be peripheral to the pressure-sensing glove.
The RFID reader 106 can be affixed to any portion of the pressure-sensing glove 102. The RFID reader 106 can also be peripheral to the pressure-sensing glove.
The NFC reader 108 can be affixed to any portion of the pressure-sensing glove 102. The NFC reader 108 can also be peripheral to the pressure-sensing glove.
FIG. 2 depicts several views of a second example pressure-sensing glove, in accordance with some embodiments. In particular, FIG. 2 depicts a pressure-sensing glove 202 and an object 210. The pressure-sensing glove 202 includes a suction and gripping apparatus 204, a proximity sensor 206, and a user-interface button 208. It is noted that the locations of these components that are displayed in the example of FIG. 2 are by way of example, and that other configurations could be used.
The suction and gripping apparatus 204 applies suction pressure to the object 210, perhaps in response to receiving a signal from the proximity sensor 206, perhaps in response to receiving a signal denoting actuation of the user-interface button 208, perhaps in response to a voice command, among numerous other possibilities that could be listed here.
The proximity sensor 206 may be configured to work in a number of different ways, perhaps using infrared, sonar, detection of a nearby RFID tag, RF communication, and/or one or more other types of proximity-detecting technologies. The proximity sensor 206 may be further configured to transmit a corresponding signal to a processor, controller, or the like of the pressure-sensing glove 202 responsive to detection of proximity of one or more items.
The user-interface button 208 may be manually operable to apply suction pressure on the object 210, and may also be manually operable to release suction pressure from the object 210. The user-interface button 208 could have any of a number of other functions as well. In an embodiment, the result of actuating the user-interface button 208 may change depending on the current state of the pressure-sensing glove 202. For example, if no current object (e.g., the object 210) has yet been identified, then actuation of the user-interface button 208 may cause the pressure-sensing glove 202 to activate its scanner and perform a scanning function to identify an object. If, however, an object has been identified but the pressure-sensing glove 202 has not yet attached to that currently identified object, then actuation of the user-interface button 208 may cause an attachment action, such as by way of the suction and gripping apparatus 204. If an object has been identified and the pressure-sensing glove 202 has attached to the currently identified object, then actuation of the user-interface button 208 may cause a release or detachment action. And certainly other possible implementations could be listed here as well.
FIG. 3 depicts several views of a third example pressure-sensing glove, in accordance with some embodiments. In particular, FIG. 3 depicts a pressure-sensing glove 302 and an object 308. The pressure-sensing glove 302 includes pressure sensors 304 and a user-interface-notification element 306. It is noted that the locations of these components that are displayed in the example of FIG. 3 are by way of example, and that other configurations could be used.
The pressure sensors 304 may be configured to work in a number of different ways, perhaps using capacitive, inductive, strain gauge, and/or one or more other types of pressure-sensing technologies. The pressure sensors 304 may be further configured to transmit a corresponding signal to a processor, controller, or the like of the pressure-sensing glove 302.
The user-interface-notification element 306 provides a notification to the user, perhaps in an illuminated form, perhaps in an audible form, perhaps in a tactile form, among numerous other possibilities that could be listed here. The user-interface-notification element 306 may be triggered in a number of different ways. For example, if the pressure exerted on a current object (e.g., the object 308) is above a pre-determined range (or upper threshold), the user-interface-notification element 306 may notify the user of the high pressure exerted on the object 308. If, however, the pressure exerted on the object 308 is below the pre-determined range (or lower threshold), the user-interface-notification element 306 may notify the user of the low pressure exerted on the object 308. And certainly, other possible implementations can be listed here as well.
FIG. 4 depicts an architectural view of an example pressure-sensing glove, in accordance with some embodiments. The example pressure-sensing glove 400 includes a communications interface 402 (that includes a transceiver 404), data storage 406 (that contains program instructions 408 and operational data 410), a processor 412, a user interface 414, peripherals 416, and a communication bus 418. This arrangement is presented by way of example and not limitation, as other example arrangements could be described here.
As stated above, the communication interface 402 includes the transceiver 404. The transceiver 404 may be configured (e.g., tuned) to receive and transmit on one of a set of channels. The transceiver 404 may be a single component, or realized as a separate transmitter and receiver, as known by those with skill in the art. The communication interface 402 may be configured to be operable for communication according to one or more wireless-communication protocols, some examples of which include LMR, LTE, APCO P25, ETSI DMR, TETRA, Wi-Fi, Bluetooth, and the like. The communication interface 402 may also include one or more wired-communication interfaces (for communication according to, e.g., Ethernet, USB, and/or one or more other protocols.) The communication interface 402 may include any necessary hardware (e.g., chipsets, antennas, Ethernet interfaces, etc.), any necessary firmware, and any necessary software for conducting one or more forms of communication with one or more other entities as described herein.
The data storage 406 may take the form of any non-transitory computer-readable medium or combination of such media, some examples including flash memory, read-only memory (ROM), and random-access memory (RAM) to name but a few, as any one or more types of non-transitory data-storage technology deemed suitable by those of skill in the relevant art could be used. As depicted in FIG. 4, the data storage 406 contains program instructions 408 executable by the processor 412 for carrying out various functions described herein, and further is depicted as containing and operational data 410, which may include any one or more data values stored by and/or accessed by the computing device in carrying out one or more of the functions described herein.
The processor 412 may include one or more processors of any type deemed suitable by those of skill in the relevant art, some examples including a general-purpose microprocessor and a dedicated digital signal processor (DSP).
The user interface 414 may include one or more input devices (a.k.a. components and the like) and/or one or more output devices (a.k.a. components and the like.) With respect to input devices, the user interface 414 may include one or more touchscreens, buttons, switches, microphones, and the like. With respect to output devices, the user interface 414 may include one or more displays, speakers, light emitting diodes (LEDs), and the like. Moreover, one or more components (e.g., an interactive touchscreen and display) of the user interface 414 could provide both user-input and user-output functionality. Other user interface components could also be present, as known to those of skill in the art. In some embodiments, the computing device does not include a user interface. Some of the elements in previous figures that may be part of the user interface 414 include the user-interface button 208 and the user-interface-notification element 306.
The peripherals 416 may include any computing device accessory, component, or the like, that is accessible to and useable by the computing device during operation. Example peripherals 416 include a GPS receiver, an altimeter, an RSSI sensor, and the like. Some of the elements in previous figures that may be part of the peripherals 416 include the scanner 104, the RFID reader 106, the NFC reader 108, the suction and gripping apparatus 204, the proximity sensor 206, and the pressure sensors 304.
In an embodiment, the various component of the pressure-sensing glove 400 are all communicatively coupled with one another via a communication bus 418 (or other suitable communication network, or the like.)
FIG. 5 depicts an example method, in accordance with some embodiments. In particular, FIG. 5 depicts a method 500 that is described by way of example as being carried out by a pressure-sensing glove such as the above-described pressure-sensing glove 100, 200, 300, or 400.
At step 502, the pressure-sensing glove identifies an object. This step may be performed in several different ways. In one embodiment, the pressure-sensing glove identifies the object by reading indicia using its scanner 104. The scanner 104 reads the information stored in the indicia and the pressure-sensing glove uses the received data to identify the object. This may involve querying a server with the received data. In other embodiments, the pressure-sensing glove may carry out step 502 by using the RFID reader 106, the NFC reader 108, and/or another type of data-acquisition device.
At step 504, the pressure-sensing glove detects an attachment event. This step may be performed in several different ways. In one embodiment, the pressure-sensing glove detects a manual triggering of the user-interface button 208. The user-interface button 208 may be manually triggered and responsively transmit a corresponding signal to a processor, controller, or the like of the pressure-sensing glove. In other embodiments, the pressure-sensing glove may carry out step 504 by detecting a signal from the proximity sensor 206. And certainly other example implementations are possible.
At step 506, the pressure-sensing glove attaches to the object that was identified at step 502. This step may be performed in several different ways. In one embodiment, the pressure-sensing glove attaches to the object by triggering the suction and gripping apparatus 204 to attach to the identified object. And certainly other example implementations are possible.
At step 508, the pressure-sensing glove determines one or more handling constraints associated with the identified object. This step may be performed in several different ways. In one embodiment, the pressure-sensing glove determines handling constraints by determining an acceptable pressure range for the object. The acceptable pressure range of the object may be determined by, as described below in connection with FIG. 6, sending to a remote server an identifier of the object, and receiving from the remote server at least one handling constraint, which again may include an acceptable pressure range associated with the object. The at least one handling constraint may also or instead include one or more other handling constraints, such as whether the object is fragile, brittle, liquid-filled, flammable, and/or the like.
At step 510, the pressure-sensing glove measures the pressure exerted on the identified object via the pressure-sensing glove. This step may be performed in several different ways. In one embodiment, the pressure-sensing glove measures the pressure exerted on the object by receiving measured pressure from the pressure sensors 304 on the pressure-sensing glove(s). And certainly other example implementations are possible.
At step 512, the pressure-sensing glove provides an indication, via a user interface, based on the measured pressure and the acceptable pressure range. This step may be performed in several different ways. The indication may be visible, audible, and/or tactile. The pressure-sensing glove may provide an indication that the measured pressure is above, within, or below the acceptable pressure range. The indication could include numerical measurements. The indication could be provided on a companion device such as a smartphone via a Bluetooth connection. And certainly other example implementations are possible.
At step 514, the pressure-sensing glove releases the object. This step may be performed in several different ways. In one embodiment, the pressure-sensing glove releases the object by triggering a release by the suction and gripping apparatus 204. The pressure-sensing glove may do this responsive to detecting that the user-interface button 208 has been actuated. The pressure-sensing glove may release the object responsive to receiving a signal from the proximity sensor 206, perhaps indicative of the proximity sensor being near a placement area for the object. And certainly other example implementations are possible.
FIG. 6 depicts an example arrangement that includes a pressure-sensing glove, a server, and a placement area for an object, in accordance with some embodiments. In particular, FIG. 6 depicts a pressure-sensing glove 602, a placement area 604, a remote proximity sensor 606, a remote server 608, and an object 610. It is noted that the locations of these components that are displayed in the example of FIG. 6 are by way of example, and that other configurations could be used.
The remote proximity sensor 606 may be configured to work in a number of different ways, perhaps using infrared, sonar, detection of a nearby RFID tag, RF communication, and/or one or more other types of proximity-detecting technologies. The remote proximity sensor 606 may be responsive to the detection of proximity of a current object (e.g., the object 610), the pressure-sensing glove 602, and/or one or more other items. In an embodiment, the remote proximity sensor 606 detects that the object 610 is nearby, and responsively sends a signal to the pressure-sensing glove 602, which may responsively trigger a release event of the object 610.
The remote server 608 may be configured to work in a number of different ways, perhaps as a database server, a file server, a web server, an application server, and/or one or more other types of servers. The remote server may be further configured to communicate to a client via LAN, Wi-Fi, Bluetooth, NFC, and/or one or more other types of wired and/or wireless technologies.
FIG. 7 depicts an example ring scanner that can be used in conjunction with a pressure-sensing glove, in accordance with some embodiments. The ring scanner 702 is an optional peripheral 416 to the pressure-sensing glove 400. If the pressure-sensing glove 400 does not include a scanner, the ring scanner 702 may be coupled with the pressure-sensing glove 400 to read indicia.
There are several other optional peripherals 416 to the pressure-sensing glove 400 including but not limited to, a headset scanner, a fixed scanner, and a scan engine, among several other possibilities.
