The present disclosure relates to methods for processing devices, the methods comprising wiping data from a device, performing at least one diagnostic test on a device, recording an outcome of the at least one diagnostic test, sorting the devices depending upon the outcome of the at least one diagnostic test, and refurbishing those devices that have passed the at least one diagnostic test to a standard operational state. The present disclosure further relates to automated systems or apparatuses for processing a multitude of mobile telecommunication devices with different operating systems, by which the devices are functionally tested according to diagnostic tests, visually graded, all digital media stored on the devices is removed, and the devices are refurbished to standard operational states.
In modern mobile telecommunication device refurbishment, performing diagnostic tests on devices even by single-device robotic stations are no longer efficient technology solutions, due, for example, to slow testing speeds, long processing times, and/or cost-ineffective automation.
Further, a number of technology limitations prolong current device processing times. Current device refurbishment technology solutions require that the devices be pre-charged. Failing batteries are not immediately detected and removed. Pre-sorting by customer, model number, or device operating system is required prior to processing to ensure proper connection with processing equipment. Manual determination of the feature set of a model of a device and/or any cosmetic damage on the device, and the concomitant requisite one or more diagnostic tests required, is inefficient, laborious, and subjective. Different devices require a different set of one or more diagnostic tests, each diagnostic test of which may be dependent upon the customer needs, model number, device operating system, or outcome of a previous diagnostic test, ultimately requiring the transfer of devices to different pieces of equipment. Human detection of counterfeit device parts or displays is also inefficient. Devices may remain idle while diagnostic tests are performed on other devices. Each of these limitations make the current rates of device processing cost-ineffective.
Existing technology requires continual movement and replacement of devices along a conveyor system that is complex, costly, and requires constant recalibration of multi-axis robotic movement apparatuses. In addition, the movement of multiple devices is time-consuming, resulting in lost time, as one mobile telecommunication device at a time must be moved to a new station, causing considerable dwell time in which each mobile telecommunication device is idle for periods of time while each mobile telecommunication device is moved.
Existing technology requires all phones to be placed on separate charging racks for several hours prior to operation, which consumes many hours of preprocessing time and the required movement of hundreds of phones.
Another drawback of existing technology is that it takes hours, sometimes days, to switch over jigs and software control for various phone models.
In view of the above, there is a need for methods for processing mobile telecommunication devices that are faster, more cost-effective, more automated, and/or more versatile.
Further, there is a need for systems or apparatuses capable of smarter mobile telecommunication device processing lines, utilizing rapid and cost-effective automation, with flexible software and mechanical capabilities that can integrate, automate, and manage various line-optimized diagnostics automation hardware components.
If methods for processing devices could be found that were faster, more cost-effective, more automated, and/or more versatile, this would represent a useful contribution to the art.
Additionally, systems or apparatuses capable of smarter mobile telecommunication device processing lines, utilizing rapid and cost-effective automation, with flexible software and mechanical capabilities that can integrate, automate, and manage various line-optimized diagnostics automation hardware components, this would also represent a useful contribution to the art.

The various embodiments of systems and methods described above may be further understood in connection with the following Examples. In addition, the following non-limiting examples are provided to illustrate the invention. The processes and systems describe what is believed will be typically effective to perform the processes indicated. However, the person skilled in the art will appreciate that it may be necessary to vary the procedures for any given embodiment of the invention, e.g., vary the steps and/or the order of steps used.
A system for processing mobile telecommunication devices includes a conveyance system with integrated pallets fixed to its belt that allow a plurality of MTDs, such as a variety of iPhone- and Android-specific mobile devices, to be placed on its pallets by an operator to be functionally tested, visually graded, and all media removed, and refurbished to a current standard operational state through a variety of built-in and selectable functions. The system provides a flexible software and mechanical solution that will drive, integrate, automate, and manage various line-optimized diagnostics automation hardware components. Devices are processed in batches (pallets), where each pallet includes 16 devices of mixed types, both Apple iOS™ and Android™. Each DUT is connected to a DUT controller. Each pallet is loaded manually or by robotic arm, which is permanently fixed to a conveyor belt with eight individual testing stations per individual testing line (i.e., side). The first six individual testing stations have common functionality with X-Y touch point control of the DUT. Each of the first six individual testing stations executes one or more of the exact same at least one diagnostic test, and after two unsuccessful attempts of any of the least one diagnostic test, a failure is logged in the Business Processing Management (“BPM”) system. The remaining two individual testing stations have sound and ambient light isolation boxes that are automatically placed over each two individual DUTs at a time. The pallets spend about four minutes at each individual testing station. After the final station, the MTDs are manually removed and placed on a conveyance system to be sorted for disposition.
The system has several non-limiting features. No pre-charging of devices is required. Battery health is automatically determined for immediate removal of bad batteries to eliminate wasted processing time. Devices are independently tested and cosmetically graded based on customer requirements and model features. Devices can be loaded and the machine automatically adjusts to the form factor and determines the proper connector and port locations for automated insertion. The system is capable of concurrently processing up to 480 MTDs per hour, up to one individual MTD every 7.5 seconds, or up to 1.9 million MTDs per year. The at least one diagnostic test can be selected from a suite of one hundred different diagnostic tests for individual processing of each individual DUT. Smart testing automatically determines the feature set of the model of MTD for each individual DUT, and then performs only those diagnostic tests that have features aligning with the model of MTD. An advanced photometric vision system can automatically and rapidly determine cosmetic damage, surface defects, and pixel level display defects, while differentiating fingerprints and dust particles from defects. Counterfeit parts can be detected on displays of DUTs based on geometry and color tone of pixels, and on cover logos.
The pallets are mechanically fixed at a center point onto the conveyor line with power, data, and audio connectors automatically plugged into the proper interfaces on each individual MTD after the device type is determined using Bluetooth wireless communication with each MTD after the MTD is placed on the pallet. The data, power, and audio connectors are fixed to a solenoid for insertion into the MTD and connected to a small, embedded controller (i.e., headless “brick” PC), mounted beneath the MTDs on the pallet. Each pallet holds 16 MTDs, or devices under test (DUTs). The conveyance system then has a multitude of pallets that travel in clockwise sequence through the conveyance system to be functionally and cosmetically processed through a variety of functions. At each individual testing station, the pallets remain still for a short period of time (i.e., approximately four (4) minutes each), before moving along to the next individual testing station.
At each of the first six individual testing stations, an X-Y arm is fixed in place and operates pneumatic plungers on mobile device touch points to facilitate the functions being operated on for each of the individual DUTs. With the assistance of the dedicated embedded computing controllers beneath each pallet, the DUT touch points are activated via an X-Y automated plunger while the embedded controller is connected to the data port and audio port of each individual DUT. At the last two individual testing stations, the pallet rests at each individual testing station for an interval of time, and a small enclosure is automatically deployed over the DUTs to allow audio and ambient light isolation for testing and machine vision photometric grading of each individual DUT. Once the audio and video processing are completed, the enclosure is automatically lifted from the DUTs before the pallet is automatically moved to the next station for further processing of the DUTs.
Management data connectivity to the conveyance system is done with a high-speed wireless local-area network (“LAN”) device built into the embedded controller located beneath each pallet. The IEEE 802.11x wireless networking connection (“WiFi”) is logically connected to the Motion Control System (“MCS”) WiFi Access Point in proximity to the conveyance system. The data connectivity allows all embedded controllers to individually communicate to an external MCS and a business Processing Management (“BPM”) System that control the state and supervisory control of the conveyance system. The BPM system also maintains a running log of the status and/or state of each individual DUT as it moves through the conveyance system. The low voltage (9/24 Volt DC) electrical power and ground connections to be used by the conveyor belt electronics that are fixed to the bottom of the pallets are implemented by lithium ion batteries on each pallet along with charging stations that are fixed near the edge of the conveyor belt and each pallet has a contactor that will transfer the electrical power to recharge the lithium ion batteries on each pallet.
The X-Y arms that are located at each station location and the sound and light enclosures at some stations are controlled by the DUT embedded controller that receives command messages from the MCS. The MCS delivers status and receives supervisory control from the BPM System.
The automatic conveyance system allows the concurrent functional processing of multiple DUTs with multiple diagnostic tests and cosmetic inspection functions at each individual testing station that the pallet moves to in sequence. The DUTs are fixed in place on the pallets and not moved by complex, expensive robotic arms or manual removal and replacement by manual operators.
The conveyance system executes concurrent parallel processing, which greatly increases production capacity while simplifying the mechanical requirements of the system. The low cost of embedded controllers allows dozens of computing engines to concurrently operate independently on each individual DUT, which significantly increases production throughput of the system. The system overcomes the limitations of existing technology by having all DUTs placed on the pallets and constantly under power and charging through the entire process. This allows phones that are on pallets awaiting the first individual testing station to be charged, and includes a check for battery health and status with a “green-light”/“red-light” indicator of charge level using smart battery charger functionality. The operator can quickly remove any bad batteries prior to entry into the first individual testing station for processing.
The conveyance system allows any form factor and any mobile operating system to be operated on as the mechanics adjust to the mobile telecommunication device form factor automatically after reading the mobile telecommunication device identification from the DUT and using a look-up table of mobile telecommunication device form factor and port location. The form factor and mobile operating software automatically adjust to the mobile telecommunication device model based on a pre-configured library of phone mechanical and logical data attributed to the mobile telecommunication device identification.
The automated conveyance system transfers data and electrical connectivity to the conveyance system through wireless data and a lithium ion battery, thus providing data and electrical connections to allow a multitude of DUTs to be continuously operated upon with simple X-Y arms fixed at each of the first six individual testing station locations to operate touch points on each individual simultaneously. The audio and ambient light enclosures on the final two individual testing stations have a camera system that moves in one axis only (i.e., y-axis) and isolates the individual DUT for necessary audio and visual inspection. This greatly simplifies audio and visual inspection, which otherwise would require robotic or manual removal and placement of each device individually in a separate sound and light chamber for processing before being placed back onto the conveyance system one at a time.
The automated conveyance system has an end-to-end throughput of at least 480 mobile telecommunication devices per hour.
The conveyance system according to an embodiment described in this Example performs at least one of the diagnostic tests listed in Table 1 below at each of the first six individual testing stations.
Each individual DUT controller is a small board computing unit designed to control eight (8) individual DUTs placed in a designated pallet. An individual DUT controller works simultaneously with other individual DUT controllers on the same pallet, and other individual DUT controls on other pallets with similar DUT controllers. Each individual DUT controller has multiple capabilities, including, but not limited to: (a) USB-host, to control USB-connectable devices, such as DUTs, Pallet, and MCS Servo Controller; (b) Ethernet, for LAN connectivity; (c) General Purpose Input/Output (“GPIO”), with LED indicators and physical buttons; (d) Audio, for output stereo (Right (“R”)/Left (“L”)) Stream; (e) Control of X-Y arm, for up to at least sixteen (16) devices under control of an individual DUT controller; (f) WLAN, WiFi Direct Network for direct communication between individual testing stations peer-to-peer.
The software stack for an individual DUT controller includes, but is not limited to, five (5) layers: (a) Hardware Abstraction Layer (“HAL”), for the multiple capabilities (a)-(f) listed above in paragraph [0048], and allowing easy migration to other individual DUT controller hardware; (b) Application Layer, to provide individual DUT controller autonomous capabilities, including, but not limited to (i) ADR/MMR, device recognition of characteristics extractions of make, model, Serial Number (“SN”), International Mobile Equipment Identity (“MEI”), and the like, (ii) Diagnostics, including running and collecting results of individual DUT diagnostic tests, (iii) Wipe, or content clearing of individual DUTs, (iv) Flash, or individual DUT SW (ROM) loading over USB, (v) Activation, or individual DUT activation process; (c) API Layer, for integration with the central BPM; (d) Automation Control of X-Y automation for touch point control; (e) DUT controller bootstrapping and update processes.
The Centralized BPM Engine is the software layer that drives the individual DUTs according to third-party, real-time configuration control. For example, the BPM Engine controls the process flows via software hooks to API. The Centralized BPM Engine includes layers, including, but not limited to: (a) the Process Flow Engine Layer, which hosts and runs process flows pre-configured with default parameters and path, and utilizes the DUT controller API to automate activities on a plurality of DUTs; (b) the Flow Hooks API Layer, which consults third party in real-time for overriding default parameters and path of a flow, provides result of a flow instance, and provides centralized real-time monitoring capabilities to assist with process control of the automated line.
An exemplary list of mobile telecommunication devices that can be processed according to an embodiment described in this Example is provided in Table 2. It is expected that the embodiment described in this Example can be implemented to process other mobile telecommunication devices yet to be released that are capable of operating Apple iOS™, Android™, or another mobile operating system capable of being installed on a mobile telecommunication device. Further, the term “mobile telecommunication device” is not to be understood to be limited to, or specifically characterized by, the list provided in Table 2.
A conveyorized system for processing mobile telecommunication devices carries multiple mobile telecommunication devices, or MTDs, operating mobile operating systems including, but not limited to, Apple iOS™ or Android™, in a computerized pallet. The MTDs in the pallet are subject to at least the following processes: (1) wiped so that there is no residual data; (2) functionally tested with at least 100 different diagnostic tests; (3) logged, along with diagnostic test results, automatically at multiple individual testing stations into Enterprise Resource Planning (“ERP”) system; (4) graded both functionally and cosmetically.
These processes are achieved by having a computerized pallet first loaded with devices by an operator. The computerized pallets on the conveyor belt travel to various individual testing stations in sequence. Each individual testing station is capable of the complete suite of diagnostic tests, so as to continue diagnostic tests not completed at previous individual testing station positions. The conveyorized system is configured in “stadium” (i.e., discorectangle, or obround) geometry, with 16 total positions, such that computerized pallets move in two lanes of 8 positions each, which move on a conveyor in continuous stadium formation, in a clockwise rotation. Each lane corresponds to half of the length of the conveyor. Each computerized pallet is loaded with unprocessed mobile telecommunication devices at the beginning of the first lane (“lane A”) and the processed mobile telecommunication devices are unloaded at the end of said lane A. While the computerized pallet remains in position at the end of said lane A subsequent to unloading of the processed lane A mobile telecommunication devices, more unprocessed mobile telecommunication devices are loaded into the computerized pallet, commencing the second lane (“lane B”). At the end of said lane B, the processed lane B mobile telecommunication devices are unloaded, and subsequently more unprocessed lane A mobile telecommunication devices are loaded into the computerized pallet, commencing lane A again. Lane A and Lane B both proceed simultaneously.
The conveyorized system for processing mobile telecommunication devices according to an embodiment described this Example performs at least one of the diagnostic tests listed in Table 3 below at each of the individual testing stations.
Each computerized pallet contains a solenoid-controlled pedestal to manipulate a mobile telecommunication device under test (DUT) up or down, and solenoid-controlled grippers for DUTs operating either Apple iOS™ or Android™ mobile operating systems. Each computerized pallet contains DUT slots for any DUT operating either Apple iOS™ or Android™ mobile operating systems. Some slots in the computerized pallet may be run empty, based on availability of DUTs received for processing. Further, each computerized pallet contains sixteen (16) DUT slots. Each individual DUT in a computerized pallet is accessible using DUT location in the computerized pallet. Individual DUTs in a specific computerized pallet are accessed, identified, labeled, and subsequently controlled as DUT number 0 through DUT number 15.
An exemplary embodiment of a solenoid-controlled pedestal for an individual DUT 100 is provided in
Each DUT in a computerized pallet is operated on independently of all other DUTs. Each DUT will be identified by the IMEI, Model Type, and Tracking Information for that specific DUT. The BPM System has preloaded requirements for each test that a first specific customer requires for a first specific DUT, which may be completely unique and different from the preloaded requirements for each test that a second customer requires for a second specific DUT in the processing system according to an embodiment described in this Example. All diagnostic test results data and status are collected and uploaded to the BPM System at each individual testing station in order to maintain a running log for a specific DUT.
Each computerized pallet is physically fixed to the conveyor and moves on the conveyor. There are sixteen (16) pallets on the conveyor, corresponding to the 16 positions of the stadium shape of the conveyor, and computerized pallets are tracked and labeled as Pallet number 0 through Pallet number 15. Each lane has eight (8) of the computerized pallets, and moves in a clockwise direction around half of the stadium conveyor. The lanes are labeled Lane A and Lane B. The computerized pallet movement will be controlled by the MCS, and each computerized pallet will move in sequence from one individual testing station to the next individual testing station with variable timing. Each computerized pallet remains at an individual testing station for approximately four minutes before moving in sequence to the next individual testing station.
At the beginning of each lane, individual DUTs are loaded onto the computerized pallet in each DUT slot by a manual operator. When an individual DUT is placed on a computerized pallet, the DUT ports are automatically examined by a photometric system and Bluetooth™ identification, which determines the DUT type, form factor, and loads testing applications. The individual DUT is then lifted, and the proper data, power, and audio jacks are automatically inserted.
An individual DUT is not required to have a charged battery. A data/charging cable is automatically inserted into each individual DUT that initiates the DUT, enabling the DUT to use a current threshold, overcoming the requirement for a charged battery. Without being bound by theory, most commercially available mobile telecommunication devices contain a data interface in the charging path to the charging control circuitry on the device. The data/charging cable automatically inserted into each individual DUT is connected to a smart hub that conforms to SmartCharge 3 and 4, which, without being bound by theory, allows for bypassing the battery within the DUT and allows the USB power to directly interface with the DUT. As soon as the DUT is connected to the smart hub, the DUT and power are accessed directly via USB.
An individual computerized pallet proceeds through eight (8) individual testing stations in a lane, labeled individual testing station 1 (“ITS1”) through individual testing station 8 (“ITS8”), with the processing steps occurring at each individual testing station according to an embodiment described in this Example provided in Table 4 below. The processing steps at each individual testing station may vary from the arrangement provided in Table 4 below.

Computerized pallet 234 is in position at the seventh individual testing station, and each pair of mobile telecommunication devices 236 of a plurality of mobile telecommunication devices on computerized pallet 234 has a small enclosure 238 deployed over each pair of mobile telecommunication devices 236 to provide for audio and ambient light isolation for testing and machine vision photometric grading of each pair of mobile telecommunication devices 236.
Computerized pallet 240 is in position at the eighth individual testing station, and each pair of mobile telecommunication devices 242 of a plurality of mobile telecommunication devices on computerized pallet 240 has a small enclosure 244 deployed over each pair of mobile telecommunication devices 242 to provide for audio and ambient light isolation for testing and machine vision photometric grading of each pair of mobile telecommunication devices 242.
Computerized pallet 246 is in position at the ninth individual testing station, and a plurality of processed mobile telecommunication devices 248 is unloaded from the computerized pallet 246. Subsequently, a plurality of unprocessed mobile telecommunication devices is loaded into the computerized pallet 246 for processing in the second lane of the conveyor 202.
Computerized pallets move from individual testing station to individual testing station approximately every four (4) minutes. Movement interval of computerized pallets from individual testing station to individual testing station is variable, and controlled by MCS software. In certain instances, some individual testing station operations may take longer than approximately four (4) minutes, in which case, the computerized pallet proceeds to the subsequent individual testing station by control of the system software, where the diagnostic tests interrupted at the previous individual testing station are reinitiated.
Generally, computerized pallet activities are designed such that all operations for each DUT are completed within four minutes. If diagnostic test operations are not completed within approximately four minutes, the diagnostic tests are completed at the subsequent individual testing stations. Each of individual testing stations 2-7 according to Table 4 above are capable of executing the same set of diagnostic tests, and after two unsuccessful attempts at any individual diagnostic test on an individual DUT, wherein the diagnostic test cannot successfully complete, the diagnostic test is logged as a failure. Individual testing stations 6 and 7, according to Table 4 above, are equipped with sound and ambient light isolation boxes that are automatically placed over multiple DUTs at once.
Each individual DUT in an individual DUT slot within a computerized pallet is held securely in place using grippers. When each individual DUT is placed in an individual DUT slot, the system automatically inserts the proper connectors for that DUT model whereby the model form factor is determined by lookup. The lookup function determines the proper form factor and then grippers automatically position to the proper form factor and hold the individual DUT in position securely.
Each individual DUT in a computerized pallet is connected to a PC brick “headless” Embedded Controller (“EC”) mounted beneath the computerized pallet. Each EC has, in an exemplary embodiment, the following specifications: Windows 10 IOT Enterprise; Intel i7 Gen 7/8 Desktop Processor 3.4 GHz 8 Cores; 64 GB RAM; 1 TB SSD Hard Drive; 2 USB 3.0 Ports; WiFi Controller; Bluetooth Controller; Ethernet LAN Port. The DUT controller serves as the “last mile” of the control for an individual DUT. The DUT controller is controlled by the BPM System and enables the BPM system to receive information and initiate operations on individual DUTs. The DUT controller is directly connected to switches and third-party peripheral equipment through USB and/or GPIO connection. A DUT controller may interact with the MCS and visual system directly or through the BPM. Computerized pallets record the DUT identification of each individual DUT that is present in a computerized pallet. Based on the DUT identification, the computerized pallet retains the make and model of each individual DUT in each slot. The port position is at the top or bottom of the DUT controller.
Each DUT slot in a computerized pallet has an audio connector jack (i.e., female 3.5-millimeter traditional headphone connection). Alternatively, an audio connector is in an audio fixture. Based on DUT make and model, the position of an audio jack is detected automatically. An audio connector jack position may be at the top or the bottom of a DUT, or may not be present at all, as some commercially marketed mobile telecommunication devices incorporate audio capabilities into a data connector.
Computerized pallets are capable of rotating each DUT independently in two dimensions (i.e., x-axis, y-axis). Each DUT in a computerized pallet is capable of being flipped horizontally and/or vertically so as to enable various functional and cosmetic diagnostic tests.
Each DUT slot in a computerized pallet has charging indicators. When an individual DUT is loaded into a DUT slot in a computerized pallet, based on the charging level of the individual DUT, a charging indicator light glows red or green. In an embodiment, if the charging level of an individual DUT is greater than, for example, 20%, the charging indicator light grows green; otherwise the charging indicator light glows red. In other embodiments, the charging level at which the charging indicator light glows green or red can be configured to reflect that the charging level of an individual DUT is greater than, or less than or equal to, a different desired percentage.
Each DUT slot allows any form factor of DUT as listed in the exemplary Supported Device List, which lists devices that can be processed by the embodiment described in this Example, as provided in Table 5 below. Each individual DUT is identified by its DUT identification, which is available to the computerized pallet system. The DUT controller attempts to detect individual DUTs by their Bluetooth signatures using the DUT controller's Bluetooth module, so as to provide another method of detection for the MCS System during the loading phase, before individual DUTs are physically connected. The Bluetooth detection augments the photometric system detection and verifies to 100% by the USB cable detection that occurs during the successful loading of an individual DUT into a computerized pallet.
Computerized pallets are powered by lithium-ion batteries located beneath each computerized pallet. Each computerized pallet individual testing station will automatically connect a charger to the lithium-ion batteries powering each computerized pallet to recharge the lithium ion batteries while the computerized pallets are stationary at individual testing stations. The lithium-ion batteries can be easily removed and replaced. In an exemplary embodiment, a lithium-ion battery powering a computerized pallet may be the M18 Battery Pack, 18 V, 9.0 Ah, Li-Ion MILWAUKEE 48-11-1890.
In an exemplary embodiment, the power budget per computerized pallet has the following specifications. A computer brick consumes 90 W of power at 18 Volts, which is equivalent to 5 A at 18 Volts. In an embodiment, the sixteen (16) phones in a computerized pallet, each of which consumes 18 W, in total consumes 288 Watts at 5 Volts or 57.6 Amps. With miscellaneous lights, the total power consumption is approximately 26 Amps at 18 V.
An embedded controller (EC) communicates with the MCS System as to which lane the respective computerized pallet belongs, and each individual testing station identifies the individual testing station the computerized pallet is stationary at during diagnostic testing. A computerized pallet EC communicates with the conveyor through the MCS system as to which lane of the conveyor the computerized pallet is positioned in. A computerized pallet EC continuously updates the MCS System on the current state of the computerized pallet. A computerized pallet EC updates the MCS System when diagnostic testing begins or concludes, respectively, upon the computerized pallet arriving at or departing from an individual testing station. A computerized pallet EC also communicates the current diagnostic testing status of each individual DUT to the MCS System.
Computerized pallets remain continuously physically connected by LAN connection. A computerized pallet EC is connected via USB 3.0 or lightning port to individual DUTs in each DUT slot. A computerized pallet EC is then connected to a local high-speed USB 3.0 hub. Each computerized pallet has its own WiFi access point that communicates to the BPM and the MCS System. In an exemplary embodiment, the USB hubs on each computerized pallet are dual eight port programmable, software-controlled, industrial USB 3.0 hubs with 8 fast-charging (4 A) ports, 2 host connections, and a dedicated port for control and monitoring, for example, Acroname programmable Industrial USB 3.0 Hub (8 Ports) Model 579-USBHUB-3P. In specific situations in which individual DUTs cannot be connected physically, such individual DUTS interact over device WiFi. Such specific situations include, but are not limited to: when an individual DUT is subjected to a wireless charging test; when an individual DUT is subjected to gyroscope and accelerometer tests in which the individual DUT needs to remain unconnected while being rotated on different axes; when an individual DUT is within an audio test chamber; and when an individual DUT is within a cosmetic grading diagnostic test enclosure.
A DUT controller is physically connected to a multiport USB hub, a GPIO device either over USB or through an embedded controller for controlling LED lights and input from physical button(s), a LAN using WiFi, and third-party equipment for example, including, but not limited to, XY arms, MCS System components, and/or photometric components, through USB, LAN, or the BPM. A DUT controller directly communicates and logs and/or reports to the BPM the current computerized pallet state, each start and stop of diagnostic testing, and the diagnostic test status of each individual DUT. Further, a DUT controller creates a local WiFi network, if a local access point is not used. A DUT controller directly controls DUTs via USB, through a high-speed USB hub, as the preferred means of communication. A DUT controller directly controls DUTs via WiFi or Bluetooth, in scenarios in which DUTs cannot be tethered, for example, including, but not limited to: when an individual DUT undergoes a wireless charging diagnostic test; when an individual DUT undergoes gyroscope and/or accelerometer diagnostic tests; when an individual DUT is within an audio test chamber; and when an individual DUT is within a cosmetic grading test enclosure.
Each individual DUT is processed independently from all other DUTs in the system. Individual DUTs are not required to be run in batches specific to a single customer. Individual DUTs from multiple different customers can be run concurrently with all DUT statuses maintained by the MCS System. Each individual DUT has the suite of tests to be performed on such individual DUT preloaded into the BPM System prior to execution. The BPM System processes each individual DUT independently, in the sense that individual DUTs may require processing differently, according to a specific customer, specific features, and/or specific make and model. The selection of diagnostic tests and processes is automatically performed by the BPM System according to a preconfigured set of rules loaded into the BPM System. An operator does not need to take an individual customer's requirements and/or limitations, or other requirements and/or limitations, when loading the system, and different customer orders are processed simultaneously without any required operator attention.
In an embodiment, the DUT controller software uses a specific framework for hardware abstraction layer (HAL), DUT connectivity, virtualization technology, inherent integration with the BPM System, logging, and reporting. This framework allows the connection of multiple variations of mobile telecommunication devices and peripherals to one DUT controller, without interference. One DUT controller can process a minimum of 16 DUTs in parallel, including data-consuming actions such as software flashing. One DUT controller can process DUTs that are capable of operating mobile operating systems including, but not limited to, both Apple iOS™ and Android™. Separation between individual DUTs operating different mobile operating systems, or DUTs of different makes or models, on a single DUT controller, is not necessary.
Individual DUTs can be accessed, identified, labeled, and subsequently controlled as computerized pallets 0-15, and DUTs 0-15.
In an embodiment, at a loading station, mobile telecommunication devices are loaded into a pallet in the DUT slots. The individual DUTs are in the powered ON state, if possible. Each individual device will show a QR Bar Code on the device display. The QR Bar Code is established at the receiving station prior to reaching the system described herein. The QR Bar Code is created as the operational screen saver on an individual DUT so that when the individual DUT is powered ON, the QR Bar Code is displayed automatically. Software at the receiving station, after an individual DUT is plugged in, reads all data about the individual DUT from low-level operating system commands that obtain all model, operating system, and critical information from the individual DUT and then creates a QR Bar Code that is displayed as the operational screen saver of the individual DUT and remains with the individual DUT for the duration of its processing. A physical QR Bar Code label is also printed and attached to an individual DUT if the individual DUT has a display issue. The QR Bar Code is analyzed by a QR Bar Code Scanner and used to communicate with the MCS System, which will then communicate with the BPM System to log the make and model of the individual DUT read from the device identification. Each individual DUT in a computerized pallet is always physically connected over USB 3.0 and kept on charge, except for the WiFi connectivity scenarios, for example, those described above in paragraphs [0082] and [0083]. For DUTs operating an Apple iOS™ mobile operating system, a FMIP check is performed. If an individual DUT is FMIP-locked, then the locked status is indicated on the display of the individual DUT and the individual DUT is removed from the DUT slot and computerized pallet. For DUTs operating an Apple iOS™ mobile operating system, each individual DUT must connect to the Apple server when an application initiates for verification purposes. Touch points can be performed using the internal diagnostic testing applications, but initial touch points may require an X-Y arm to hit touch points before an application can execute. Accordingly, such individual DUTs operating an Apple iOS™ mobile operating system are trusted and activated using an X-Y arm. An MCE testing application with data-wipe is loaded into the individual DUT. The MCE testing application is executed and all local digital media storage on the individual DUT is erased. If an individual DUT is operating on an old mobile operating system that is not the latest release of the mobile operating system, the individual DUT may be flashed with the latest firmware release. The current charge of the individual DUT is detected, and for example, if the charging level is less than 20%, the red LED light indicator is illuminated on the DUT slot. The DUT chargers used in the system are intelligent fast chargers capable of 3.5 Amps per DUT. Each individual DUT charging status is available in the user interface that can be selected through the BPM System. Each individual DUT is processed as an individual entity, regardless of other DUTs from other customers, in which the tests to be performed on an individual DUT are selected by a customer beforehand and loaded into the BPM System. Each individual DUT has its SIM card tested prior to the individual DUT being loaded onto the computerized pallet. Additionally, extra stickers and dirt are removed.
An exemplary list of mobile telecommunication devices that can be processed according to an embodiment described in this Example is provided in Table 5. It is expected that the embodiment described in this Example can be implemented to process other mobile telecommunication devices yet to be released that are capable of operating Apple iOS™, Android™, or another mobile operating system capable of being installed on a mobile telecommunication device. Further, the term “mobile telecommunication device” is not to be understood to be limited to, or specifically characterized by, the list provided in Table 5.
In an embodiment, according to a Data-Wipe Execution, the data-wipe and/or flashing processes are available at each individual testing station. During the data-wipe and/or flashing processes, the charge level of each individual DUT is detected and compared with the initial charge level recorded for that individual DUT. If for an individual DUT, the rate of charging is slow and/or the battery health is poor, a red LED light is indicated on the corresponding individual DUT slot. Individual DUTs with red LED lights indicated on the corresponding DUT slots are removed by an operator. If the duration of data-wipe and/or flashing processes is longer than approximately four minutes, then computerized pallet movement to a subsequent individual testing station may be delayed. Once the data-wipe process for an individual DUT is completed, a MCE Diagnostics application is installed on the individual DUT. Further, a WiFi profile is installed on the individual DUT, but the individual DUT is not connected to WiFi. A Data-Wipe Execution result, along with any generated data, is uploaded to the BPM System.
In an embodiment, according to a Device Touch Screen diagnostic test, each individual DUT is tested using an external X-Y Cartesian device (“X-Y arm”). The Device Touch Screen diagnostic test recognizes a touch event over an area of each individual DUT screen. A pattern of squares is drawn on the individual DUT screen, and the Device Touch Screen diagnostic test determines if touch points displayed on the individual DUT screen correlate properly to the positions that a digitizer determines for the same touch points. Three-dimensional touch is detected using the X-Y arm. The arm presses buttons with specific pressures, and an application on each individual DUT determines PASS/FAIL. A Device Touch Screen diagnostic test result, along with any generated data, is uploaded to the BPM System.
In an embodiment, according to a WiFi diagnostic test, for each individual DUT, the WiFi is initiated and the individual DUT attempts to scan for and detect a WiFi Access Point Name (“APN”).

Location services are deactivated on the individual DUT subsequent to the GPS diagnostic test. A GPS diagnostic test result, along with any generated data, is uploaded to the BPM System.
In an embodiment, according to a Near-Field Communication (“NFC”) diagnostic test, for each individual DUT, the NFC feature is activated.

A Wireless Charging diagnostic test result, along with any generated data, is uploaded to the BPM System.
In an embodiment, according to a Camera diagnostic test(s), for each individual DUT, the camera flash is activated and the camera flash is detected by determination of the changes in luminance levels. The camera flash is detected by the ambient light sensor on the individual DUT. Rear and front camera image capture on each individual DUT are triggered using an X-Y arm and verified against reference images. Rear and front camera videos on each individual DUT are triggered using an X-Y arm and the video and record sound are verified by a photometric system. One or more Camera diagnostic test(s) result(s), along with any generated data, is uploaded to the BPM System. The rear and front camera video and audio recorded in the Camera diagnostic test(s) are verified by the Vision System.

In an embodiment, according to a Sensor Light Sensor diagnostic test, the ambient light sensor of each individual DUT is tested by analyzing sensor luminance values of the environment surrounding the individual DUT. The ambient light sensor of the individual DUT is covered by a black plastic block, and changes in ambient light sensor values are detected. A Sensor Light Sensor diagnostic test result, along with any generated data, is uploaded to the BPM System.
In an embodiment, at an Audio Test Station, the 3.5-millimeter female audio jack connector of each individual DUT with a 3.5-millimeter female audio jack is tested by inserting a 3.5-millimeter male audio jack connector of a headset into the 3.5-millimeter female audio jack of the individual DUT and subsequently removing the 3.5-millimeter male audio jack connector. The 3.5-millimeter male audio jack connector should be detected within the 3.5-millimeter female audio jack connector of the individual DUT. A diagnostics application on the individual DUT plays back a specific reference audio file, and the Audio Test Station determines PASS/FAIL if an input is within the required decibel (“dB”) specific range. The Audio Test Station plays back a test audio speech and sound file, and the test audio speech and sound file is recorded using a microphone of the headset. The test audio speech and sound file is played back and the Audio Test Station determines PASS/FAIL based on the dB range. One or more Audio Test Station diagnostic test(s) result(s), along with any generated data, is uploaded to the BPM System.
In an embodiment, according to an Earpiece diagnostic test, the earpiece of each individual DUT is tested by an application that plays back a specific audio file, and an audio analyzer records the specific audio file.

A Vibration diagnostic test result, along with any generated data, is uploaded to the BPM System.
In an embodiment, at a Cosmetic Grading Station, all external stickers on each individual DUT are removed manually to ensure that the entire surface of the individual DUT is visible and can be cosmetically graded. Further, the individual DUT is cleaned as necessary. In certain embodiments, each individual DUT can be cleaned automatically in a separate processing step, in order to avoid incorrect grading. At a Cosmetic Grading Station, a chamber is capable of capturing images of all 6 sides of an individual DUT. Each individual DUT is removed from the grippers and held using suction cups or another appropriate mechanism. The images of all 6 sides of the individual DUT are analyzed by a grading analyzer based upon the number and size(s) of scratch(es)/wear and tear/dent(s)/ding(s)/discoloration(s) on the individual DUT. An appropriate grade is given to the individual DUT based upon defined Grading Criteria provided, for example, in Table 6 below. Grading criteria are configurable in the BPM System software. A Cosmetic Grading Station can distinguish among dust particles, chips, dents, foreign material, fingerprints, light transmission performance material, glass, and covers. A Cosmetic Grading Station can determine the depth and width of a scratch. All Cosmetic Grading Station diagnostics results, along with any generated data, is uploaded to the BPM System.
In an embodiment, according to a LCD color diagnostic test, each individual DUT display screen is progressively filled with five individual colors. A vision system verifies if the individual DUT display screen properly displays each of the individual colors. The computerized pallet EC controller controls each individual DUT to display the different individual colors. A LCD color diagnostic test result, along with any generated data, is uploaded to the BPM System.
In an embodiment, according to a LCD dimming diagnostic test, each individual DUT display screen is tested for whether the individual DUT display screen is capable of dimming.

In an embodiment, according to a LCD ghosting diagnostic test, each individual DUT display screen is progressively filled with five individual colors. A vision system verifies if the individual DUT display screen demonstrates any “ghost effect” (i.e., an outline of a previous image that can be seen super-imposed over the current image on the individual DUT display screen). A LCD ghosting diagnostic test result, along with any generated data, is uploaded to the BPM System.
In an embodiment, according to a LCD dead pixel diagnostic test, each individual DUT display screen is progressively filled with five individual colors. A vision system verifies if the individual DUT display screen demonstrates any “dead pixels” (e.g., a pixel remains black while the rest of the individual DUT display screen displays white). Depending on the individual DUT display technology and/or screen chemistry, a dead pixel may demonstrate a color other than black. A LCD dead pixel diagnostic test result, along with any generated data, is uploaded to the BPM System.
In accordance with the embodiment as described in this Example, an exemplary audio and triage grading criterion is provided below in Table 6. The embodiment as described in this Example may be configured with other audio and triage grading criteria.
Each individual DUT is data-wiped subsequent to processing and data-wipe execution is automatically verified. The QR Bar Code application is removed during the data-wipe execution, and a corresponding QR Bar Code sticker is automatically printed on the individual DUT.
English and Spanish languages are supported by all components of the system. In various embodiments, the components of the system may support additional languages.
In certain exemplary embodiments, the computerized pallets at each of four or more of the first six individual testing stations in each lane are equipped with 2 independent X-Y arms. The Cartesion robotic systems used to equip the individual testing stations are acquired from one or more of Macron Dynamics, Newmark Systems, Yamaha-Motor.com, and/or IselAutomation.
A one-time teaching process is contemplated for each form factor for each possible operation before optimal automation of the conveyorized system. The origin location of each individual DUT in the individual DUT slot is defined by the computerized pallet embedded controller, based upon each individual DUT make and model. An X-Y arm extrapolates the offset X-Y coordinates based on the form factor of an individual DUT and the location of the individual DUT in the computerized pallet.
At a User Interface Station (“UIS”), all of the information being stored in the BPM System is displayed to a user or operator. A dashboard allows the user or operator to view a current status of the conveyorized system according to an embodiment described in this Example. Multiple individual DUTs process through various individual testing stations in parallel, and the processing of the individual DUTs are intelligently displayed at the UIS. At the UIS, a user or operator is able to review the processing details for each individual DUT on the individual DUT “Details” page. Further, a user or operator can scan the QR Bar Code of an individual DUT to review the processing details for that individual DUT.
Control over the processing activity of the DUT controllers is performed by the BPM System, which provides an “operation view” per lane of the conveyorized system and per DUT controller in each lane. Each DUT controller is connected using GPIO to LED lights in order to provide charge status, FMPI, and other indications to a user or operator that an individual DUT requires attention. Complete information regarding any issue with processing of an individual DUT is available to a user or operator in the “operation view.” Each DUT controller is also connected to physical buttons for basic interaction of a user or operator with the conveyorized system, including, but not limited to, starting and/or stopping of computerized pallet operations, starting and/or stopping of the conveyor belt.
DUT controller software is integrated into several software and hardware components according to an embodiment described in this Example. The BPM System integrates with each DUT controller on the MCE framework, which uses the BPM System to initiate actions on the DUT controller. An X-Y arm integrates with each DUT controller for any “finger” interaction with each individual DUT, optionally at the BPM System. Smart chargers integrate with each DUT controller to determine whether batteries in individual DUTs have faulty batteries and to communicate external battery data. In an embodiment, individual LED lights integrate with GPIOs on DUT controllers that turn on or off the individual LED lights according to individual DUT status. In another embodiment, individual LED lights integrate to a DUT controller and are controlled directly from the BPM System.
It is expected that a conveyorized system according to an embodiment described in this Example, operating at approximately 4 minutes per individual testing station in a single lane, can process 16 mobile telecommunication devices every 4 minutes, and can complete processing of 16 mobile telecommunication devices 15 times each hour. Accordingly, a conveyorized system according to such an embodiment described in this Example could be capable of processing 240 mobile telecommunication devices per hour per lane. With two lanes in parallel operation, a conveyorized system according to such an embodiment described in this Example could be capable of processing 480 mobile telecommunication devices per hour. Accordingly, a conveyorized system according to such an embodiment described in this Example could be capable of processing 8 mobile telecommunication devices per minute, or 1 mobile telecommunication device every 7.5 seconds.
It is expected that a conveyorized system according to another embodiment described in this Example, operating at approximately 3 minutes per individual testing station in a single lane, can process 16 mobile telecommunication devices every 3 minutes, and can complete processing of 16 mobile telecommunication devices 20 times each hour. Accordingly, a conveyorized system according to such an embodiment described in this Example could be capable of processing 320 mobile telecommunication devices per hour per lane. With two lanes in a parallel operation, a conveyorized system according to such an embodiment described in this Example could be capable of processing 640 mobile telecommunication devices per hour. Accordingly, a conveyorized system according to such an embodiment described in this Example could be capable of processing 10.67 mobile telecommunication devices per minute, or 1 mobile telecommunication device every 5.6 seconds.
It is expected that a conveyorized system according to yet another embodiment described in this Example, operating at approximately 2 minutes per individual testing station in a single lane, can process 16 mobile telecommunication devices every 2 minutes, and can complete processing of 16 mobile telecommunication devices 30 times each hour. Accordingly, a conveyorized system according to such an embodiment described in this Example could be capable of processing 480 mobile telecommunication devices per hour per lane. With two lanes in a parallel operation, a conveyorized system according to such an embodiment described in this Example could be capable of processing 960 mobile telecommunication devices per hour. Accordingly, a conveyorized system according to such an embodiment described in this Example could be capable of processing 16 mobile telecommunication devices per minute, or 1 mobile telecommunication device every 3.75 seconds.
Automation is more consistent and faster than a human due to fatigue over a long period of time, so automation could be expected to process a mobile telecommunication device consistently in less than 15 minutes. If a conveyorized system according to yet another embodiment described in this Example could process a mobile telecommunication device in approximately 16 minutes, with two lanes in parallel operation, a conveyorized system according to such an embodiment described in this Example could completely process 32 mobile telecommunication devices every 2 minutes, or 960 mobile telecommunication devices every hour.
Throughput is increased by having more individual testing stations operating concurrently, so more individual testing stations results in an increased processing rate. By comparison, manual processing of mobile telecommunication devices could require 30 people working daily 8-hour shifts to process approximately 960 mobile telecommunication devices, at a rate of 15 minutes per phone per person.
In an exemplary embodiment of a computerized pallet that can be configured to carry mobile telecommunication devices within a conveyorized system for processing, the computerized pallet includes a plurality of slots for mobile telecommunication devices. One nonlimiting example of a plurality of slots is 16 slots in a computerized pallet. Each mobile telecommunication device (MTD), or device under test (DUT), occupies one slot of the plurality of slots in each computerized pallet, all of which simultaneously index to move through, and stop at, different individual testing stations of a conveyorized system. At individual testing stations, each individual DUT is handled and manipulated by a plurality of actuators within each computerized pallet and at each individual testing station. Because each individual actuator of a plurality of actuators operates very closely to other individual actuators and each individual actuator must clear other individual actuators to fit and function mechanically, the individual actuators are illustrated collectively in
Within each computerized pallet, individual actuators of a plurality of actuators supplied to an individual DUT 300 of a plurality of DUTs placed in an individual slot of a plurality of slots may include, but are not limited to: gripping actuator 302 for gripping of the individual DUT 300 in an individual slot; flipping and/or rotating actuator(s) 304 for flipping and/or rotating of the individual DUT 300 in an individual slot during diagnostic testing of the camera(s) of the individual DUT 300; vertical lifting and/or positioning actuator 306 for elevation of a surface of the individual DUT 300 for diagnostic testing of the camera(s) and so that a X-Y arm can confront the surface.
In certain exemplary embodiments of conveyorized systems, a conveyor includes two lanes operating independently, each of which includes 5 individual testing stations equipped with one or more X-Y arms operating independently. To allow a X-Y arm or gantry to confront a touchscreen and/or hard buttons of the individual DUT 300, individual actuators of a plurality of actuators supplied to each individual testing station equipped with one or more X-Y arms operating independently may include, but are not limited to: vertical support actuator 308 to support the bottom of the individual DUT 300 for push button support pushing down on the individual DUT 300.
In certain exemplary embodiments of conveyorized systems, a conveyor includes lanes operating independently, each of which includes 2 camera individual testing stations, elements of which may be moved around and into an individual testing station from above and/or below an individual computerized pallet, and interact with the individual DUT 300 within an individual slot of a plurality of slots. To activate an audio jack port of the individual DUT 300, individual actuators of a plurality of actuators supplied to each camera individual testing station may include, but are not limited to: top and bottom 3.5 audio jack actuators 310, with two audio jack actuators 310 per individual DUT slot; index upper 3.5 audio jack to phone height actuator 312.
In certain exemplary embodiments of conveyorized systems, a conveyor includes lanes operating independently, each of which includes a receiving station, elements of which may be moved upwards to an individual computerized pallet from below the individual computerized pallet, and interact with the individual DUT 300 an individual slot of a plurality of slots of the computerized pallet. In order to automate the individual DUT 300 being held in place and plugged in with its corresponding charge and data sync connector, individual actuators of a plurality of actuators supplied to each receiving station may include, but are not limited to: connector insertion actuator 314; DUT location actuators 316, with two DUT location actuators 316 for the individual DUT 300, one each on the front and back of the individual DUT 300, so as to horizontally center DUT ports of the individual DUT 300 over a connector; DUT vertical centering actuator 318, with gripper and connector ports; index connector actuator 320, with selection from connector types.
In certain exemplary embodiments of conveyorized systems, the system may be configured to process any type of DUT 400, which may comprise any smartphone device. The system may be structured to upload data from DUT 400. The system may use the uploaded data to determine at least the DUT 400 model type to known, for example, the physical characteristics of DUT 400. The information pulled may also be used to compare the physical characteristics of DUT 400 to a database lookup of known physical characteristics of the phone model type of DUT 400. The information pulled may be used to determine, for example, the exact location and type of USB port 402 of DUT 400, for automatic insertion of USB cable, automatic height adjustment and automatic location adjustment for phone pedestal 435 used. The DUT 400 may be secured to a pallet 409. Each pallet 409 may include a plurality of cells so that, for example, a given cell may be associated with a given DUT 400. Each of the plurality of cells may comprise a LED indicator, for example, a green LED indicator. After the phone model is determined, for example, the correct USB connector may be automatically inserted into USB port 402 for a given phone model type. The DUT 400 may be secured to pallet 409 with a gripping device, for example. The gripping device may hold and suspended the DUT 400 on pallet 409 as it moves along the conveyor from test station to test station. The DUT 400 may be flipped or rotated to expose all sides for a photometric analysis to determine a cosmetic grade of the DUT 400, for example. The pallet 409 may finish the process by moving to a final position where DUT 400 may be released from the pallet.
