DETAILED DESCRIPTION

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. Methods and materials similar or equivalent to those described herein can be used in the practice or testing of the present disclosure. As used in the specification, and in the appended claims, the singular forms “a,” “an,” “the” include plural referents unless the context clearly dictates otherwise. The term “comprising”, and variations thereof as used herein is used synonymously with the term “including” and variations thereof and are open, non-limiting terms. The terms “optional” or “optionally” used herein mean that the subsequently described feature, event or circumstance may or may not occur, and that the description includes instances where said feature, event or circumstance occurs and instances where it does not. Ranges may be expressed herein as from “about” one particular value, and/or to “about” another particular value. When such a range is expressed, an aspect includes from the one particular value and/or to the other particular value. Similarly, when values are expressed as approximations, by use of the antecedent “about,” it will be understood that the particular value forms another aspect. It will be further understood that the endpoints of each of the ranges are significant both in relation to the other endpoint, and independently of the other endpoint. As used herein, the terms “about” or “approximately” when referring to a measurable value such as an amount, a percentage, and the like, is meant to encompass variations of ±20%, ±10%, ±5%, or ±1% from the measurable value.


In some aspects, an automated parcel machine (APM module) includes: a body (e.g., locker body 102 in FIG. 1) including a plurality of parcel insertion slots; and a device board 500 (e.g., device board 500 in FIGS. 5 and 6) for controlling operations of the APM module. The device board includes a controller (e.g., APM MC 502 in FIGS. 5 and 6.) including: at least one processor and at least one memory operably coupled to at least one processor (e.g., basic computing configuration of box 802 in FIG. 11).


Additionally, the controller (e.g., APM main controller (MC) 502) includes a low-power wide-area module configured for communication with a server over a first communication link. Optionally, the first communication link comprises a cellular network. A low-power wide-area (LPWAN) is a type of wireless communication network designed to provide long-range connectivity for Internet of Things (IoT) devices while consuming minimal power. LPWANs are specifically optimized for devices that require low data rates, long battery life, and extended coverage areas. An example technology for LPWAN communications is the narrowband IoT (NB-IoT) or Long Term Evolution Machine Type Communication (LTE-M) standard. It should be understood that NB-IoT protocol and LTE-M standard are provided only as an example. This disclosure contemplates using other standards or protocols for LPWAN communications.


Further, the controller (e.g., APM MC 502) includes a low-power personal-area module configured for communication with a second APM module (e.g., extra module 101 in FIG. 1) over a second communication link. Optionally, the second communication link is a Bluetooth low-energy (BLE) link. Wireless Personal Area Network (WPAN) is a type of wireless network that enable communication between devices in close proximity to each other, typically within a range of a few meters (e.g. maximally within 10 meters, preferably within 2-5 meters). WPANs are designed to support low-power and short-range communication between devices and are often used for applications like wearable devices, health monitoring systems, home automation, and wireless peripheral connections. An example communication standard for WPAN is BLE. It should be understood that BLE is provided only as an example. This disclosure contemplates using other standards or protocols for WPAN communications.


According to this disclosure, the APM module such as main module 100 (PIN pad only main module shown in FIG. 1) or main module 300 (PIN pad and display main module shown in FIG. 3) can communicate with one or more additional APM modules such as extra module 101 (e.g., using the second communication link) while simultaneously communicating with the server (e.g., using the first communication link). For example, a second APM module (e.g., extra module 101) can communicate slot status information (e.g., filled, empty, disabled, opened, etc.) to a first APM module (e.g., main module 100 or 300) using a BLE link, and the first APM module (e.g., main module 100 or 300) can synchronize slot status information with a server using a cellular network. In particular, the low-power personal-area module (e.g., BLE link) is used to connect the APM MC 502 inside the main module 100 or 300 to APM sub-controller (SC) 700 inside the extra module 101. In addition, the low-power personal-area module (e.g., BLE link) is used to establish a connection between the APM MC 502 inside the main module 100 or 300 and a mobile courier application. An advantage of this configuration, which uses multiple information/communication channels, is the ability to update a package registry almost immediately. Existing technologies do not have multiple information/communication channels and therefore the registry can be updated only after some time has passed from a package inserted to or received from the machine. According to existing technologies, an automated parcel machine can only send information to a server to update the registry essentially immediately only when a user connects a mobile device to the APM, i.e., the user's app acts as a link between the server and automated parcel machine. In contrast, the APM (e.g., main module 100 or 300) of the present disclosure includes both a low-power wide-area module and a low-power personal-area module to address deficiencies of existing technologies.


In some aspects, a system includes: a first APM module (e.g., main module 100 or 300) and a second APM module (e.g., extra module 101). The first APM module (e.g., main module 100 or 300) includes: a first body including a first plurality of parcel insertion slots, and a first device board (e.g., device board 500) for controlling operations of the first APM module, the first device board including a first controller (e.g., APM MC 502) including: at least one first processor; at least one first memory operably coupled to the at least one first processor; a low-power wide-area module configured for communication with a server over a first communication link; and a first low-power personal-area module configured for communication with the second APM module (e.g., extra module 101) over a second communication link. Additionally, as described herein, the first low-power personal-area module may be configured to establish the connection between the first APM module (e.g., via APM MC 502) and the mobile courier application. The second APM module (e.g., extra module 101) includes: a second body including a second plurality of parcel insertion slots, and a second device (e.g., APM SC 700) board for controlling operations of the second APM module, the second device board including a second controller including: at least one second processor; at least one second memory operably coupled to the at least one second processor; and a second low-power personal-area module configured for communication with the first APM module (e.g., main module 100 or 300) over the second communication link.


Optionally, the system includes more than two automated parcel machines. For example, the system may include a third APM module. A third APM module includes: a third body including a third plurality of parcel insertion slots, and a third device board for controlling operations of the third APM module, the third device board including a third controller including: at least one third processor; at least one third memory operably coupled to the at least one third processor; and a third low-power personal-area module configured for communication with the first APM module over the second communication link.


Optionally, the system may include a fourth APM module. This disclosure contemplates that the fourth APM module includes: a fourth body including a fourth plurality of parcel insertion slots, and a fourth device board for controlling operations of the fourth APM module, the fourth device board including a fourth controller including: at least one fourth processor; at least one fourth memory operably coupled to the at least one fourth processor; and a fourth low-power personal-area module configured for communication with the first APM module over the second communication link. Again, it is to be understood that the system is not limited to four APM modules but may include further APM modules with similar logic.


In some implementations, the automated parcel machine (APM) can include one main module 100 or 300 and a plurality of extra modules 101. Optionally, the APM can include one main module 100 or 300 and two extra modules 101. Optionally, the APM can include one main module 100 or 300 and three extra modules 101. Although APMs having two and three extra modules 101 are provided as examples, this disclosure contemplates providing an APM with one extra module 101 or more than three extra modules 101, e.g., four, five, etc. extra modules 101. It should also be understood that the APM can include solely one main module 100 or 300 as described herein (i.e., with no extra modules 101).


Referring now to FIG. 1 and FIG. 3, an automated parcel machine (APM) is shown. The APM shown in FIG. 1 and FIG. 3 is a battery powered APM for handover of online orders.


Optionally, the APM is designed for location in an outdoor environment. The APM according to this invention is subdivided into two types of units:

    • Main module 100 or 300 acting as the APM control unit.
    • Extra module 101 being the supplementary unit to the main module with the purpose of increasing the number of parcel slots.


The main module comprises an outer shell, device board, and user interface. The extra module includes an outer shell and device board.


Detailed View of the Components
Outer Shell

Still referring to FIG. 1 and FIG. 3, the outer shell of the APM is preferably composed of sheet metal having a thickness of 0.5-2 mm, preferably 0.8-1.5 and most preferably 0.8 . . . 1.2 mm. Materials other than sheet metal may be used. This acts as the locker body 102 structure assembled on top of a base frame 103, the base frame preferably being sheet metal with thickness between 2-4 mm preferably 3 mm supported by leveling feet 106. For APM stability the base frame is filled with concrete blocks or other stabilizing heavy material. In front of both the main module 100 and the extra module 101, are situated parcel insertion slots covered with doors 104. Each door is preferably made of double-layered 0.8 mm sheet metal and is latched by using a motor lock. The doors may comprise other materials as well. A special case of a door for user interface appearing only on the main module 100 or 300 has two configurations:

    • PIN pad only door 105 on main module 100
    • PIN pad and display door 301 on main module 300


On the main module 100 or 300, a cellular network antenna 506 is mounted on the roof 600. All the outer shell surfaces can be covered as desired, e.g., different color choices, advertisement areas etc.


APM User Interface

In some versions, the PIN pad door 105 is part of the main module 100 and the PIN pad door acts as a starting point for human to machine (APM) communication. FIG. 2 illustrates an example human-to-APM communication interface. With reference to FIG. 2, it has an identification code plate 200. The identification code, for example a QR code, carries a specific ID value of the APM, used to identify the main module 100 through scanning operation by a mobile courier application. This app is used for parcel insertions. For the end user parcel retrieval functionality, the PIN pad door 105 has a numerical PIN pad 201 installed. By entering the correct numerical combination, the corresponding parcel slot covered with door 104 opens.


In some versions, the PIN pad and display door 301 is integrated into the main module 300 and the integrated PIN pad and display door acts as a starting point for human to machine (APM) communication. FIG. 4 illustrates an example human-to-APM communication interface. With reference to FIG. 4, the door has an identification code 200 with a unique ID, facilitating mobile courier application and parcel insertions. The addition of TFT display 400 offers an alternative way of parcel insertions by using a numerical PIN pad 201. The TFT display 400 interacts with the user by showing feedback messages. The PIN pad 201 can further be used for parcel retrieval by the end user.


Display Controller

In the PIN pad and display door 301 the display controller 401 is present. It is responsible for managing the operations of the TFT display 400. The reflective technology used in the TFT display 400 harnesses ambient irradiance, ensuring visibility during the daytime while minimizing energy use. At night, the TFT display 400 is equipped with a front light, which is regulated by an ambient light sensor 402. The display controller 401 communicates with the device board 500 via I2C.


Device Board

Both the main module 100 or 300 and the extra module 101 have a device board with a specific configuration based on the unit type and the number of parcel insertion slots covered by doors 104 per module. The device board forms a ceiling panel in the upper right parcel compartment for each module type.


Device Board Inside the Main Module

Referring now to FIGS. 5, 6 and 7, APMs including device boards are shown. FIG. 5 illustrates the main module 100 with PIN pad only door 105 and its device board 500. FIG. 6 illustrates the main module 300 with PIN pad+display door 301 and its device board 500. FIG. 7 illustrates the extra module 101 and its device board 500. In the main modules 100 or 300, the device board 500 has the main controller (MC) 502 attached on DIN rail 501. The MC is responsible for the controlling operations of the main module and receives PIN pad 201 data via I2C bus. Inside the MC 502 two submodules are included:

    • Low-Power Wide-Area (LPWA) module connects the APM via LTE-M or NB-IoT network to the server. This server-APM connection is established after a predefined time interval. Information e.g., APM slot status (filled/empty/disabled/opened) is exchanged. To improve the connection quality, LPWA module (MC 502) has an external cellular network antenna 506 with a coaxial cable.
    • Bluetooth Low Energy (BLE) module connects the main controller 502 inside the main module 100 or 300 to the sub-controller (SC) 700 inside the extra module 101. In a preferred embodiment three sub-controllers 700 are enabled to connect to a single main controller 502, meaning each main module 100 or 300 can communicate with three extra modules 101. It is to be understood that more than three sub-controllers may be enabled to connect to a single main controller. In addition, the BLE module establishes the connection between the MC 502 and the mobile courier application.


The MC 502 controls an extension bus (the bus) 505. The extension bus 505 carries battery power, logic power, I2C signals and addressing signals for additional functional modules attached to the DIN rail 501. The power supplies for the bus 505 can be enabled and disabled by the MC 502. The power supplies for the bus 505 are protected against overcurrent by the MC 502. Functional modules attached to the bus are controlled by the MC 502 via I2C. The MC 502 places an initial address value on the bus.


Functional modules 503 attached to the bus 505 determine their I2C address by a combination of their function and the address received on the bus 505. Functional modules pass the power and I2C on to the next functional module unmodified, enabling daisy-chaining. Addressing information received on the bus 505 is passed on modified as follows: If it is possible to connect multiple of one type of functional modules to the bus 505, then each module increments the address on the bus 505 before passing it on to the next functional module; If only one type of functional module can be connected to the bus, then the functional module ignores the address on the bus and passes the initial address value on to the next functional module. Functional modules may be mounted on the DIN rail or attached to the extension bus via cable (not pictured) and mounted separately.


I/O (input/output) modules 503 are electrical interfaces for opening the door locks and reading the door state from the door locks. I/O modules 503 are functional modules as described in the previous paragraph and are thus controlled by the MC 502 via the extension bus 505.


In a preferred embodiment, each I/O module 503 has eight lock output ports, meaning the number of I/O modules inside the APM unit is defined by a ceiling function of parcel insertion slot covered with door 104 count divided by eight.


The main module 100 is powered by at least one, and preferably by three non-rechargeable primary batteries 504 dimensioned to last the lifetime of the APM. For the main module 300, the number of batteries is higher than in the main module 100, preferably five, due greater energy consumption caused by the TFT display 400 and display controller 401. Each battery is separately connected to the MC 502.


Device Board Inside the Extra Module

In the extra module 101 the device board has on DIN rail 501 attached the sub-controller (SC) 700. The SC 700 carries out the controlling operations of the extra module. Inside the SC 700 a BLE module is included, enabling a wireless BLE connection between the SC 700 inside the extra module 101 and MC 502 inside the main module 100. The SC 700 controls an extension bus 505 identical in function to the one controlled by the MC 502. The I/O modules 503 attached to the SC 700 extension bus 505 are identical to the ones attached to the MC 502.


The extra module 101 is powered by a single non-rechargeable primary battery 504 connected to the SC 700. The battery 504 in extra module 101 is dimensioned to power the module for the lifetime of the APM.


Parcel Insertion Flow

Referring to FIGS. 8 and 12, two example parcel insertion flows could be distinguished:

    • Parcel insertion flow over mobile network. The transfer of order information between the APM and server occurs over mobile network (LTE-M, NB-IoT). This flow is possible with the PIN pad and display main module 300 (FIG. 6), optionally paired with extra module(s) 101.
    • Parcel insertion flow over courier mobile application. The application acts as a link between the server and the APM MC 502. This flow is possible with both the PIN pad and display main module 300 (FIG. 6) and the PIN pad only main module 100 (FIG. 1), optionally paired with extra module(s) 101.

    • 12. Server creates an APM session,
    • 13. Server responds to the courier application with an authentication token,
    • 14. Courier application sends the authentication token to the APM MC 502,
    • 15. APM MC 502 validates the authentication token and marks the mobile device connection as trusted,
    • 16. Courier application requests APM synchronization from the server,
    • 17. Server responds to the courier application with initial configuration data and a communications trigger packet,
    • 18. Courier application writes the initial configuration data and the communications trigger packet to the APM MC 502,
    • 19. APM MC 502 updates its configuration according to the provided configuration data and creates and sends a CoAP request containing APM events to the courier application,
    • 20. Courier application forwards the CoAP request to the server,
    • 21. Server registers each APM event contained in the CoAP request and sends communications trigger packets to the courier application until all of the events have been received,
    • 22. Server registers a receive action for each slot opening event received,
    • 23. Server publishes received parcel notifications to other services,
    • 24. Server responds to the courier application to indicate that the synchronization has been completed.
