[0016] Wireless power can be a means of improving manufacturing productivity and reliability, while reducing operating expenditures. For production facilities today, there are several notable issues for manufactured goods: quality control, downtime, and high operating expenses. This is especially true for quality control stations that require the worker to physically connect the test equipment to manufactured products with multiple functions (e.g., car seats, car doors, TVs, and phones). Complex products, such as automotive and consumer electronic products, require a multitude of electrical tests to confirm that they’re operating effectively. For quality control, there are often multiple test stations that verify each function (e.g., fans, heaters, sensors, memory, and motors).

[0017] Each station requires a worker to physically connect the test equipment and power line into the product to verify the tested function. There are often quality issues whereby the connectors physically wear down, the connector terminals fret, or the connectors were simply forced in the incorrect polarity, which often damages the connector and / or harness and requires additional review and replacement. This not only causes the product to fail, but also creates downtime since it halts the quality control stations from proceeding with the next product on the production line. This problem is even more profound during a false positive where the product passes inspection prior to being damaged and then fails at an Original Equipment Manufacturer facility (OEM) (e.g., Toyota, GM, Ford, Nissan, Chrysler, Mazda, etc.) or directly with the consumer. Furthermore, the downtime penalty OEMs charge suppliers can often be tens of thousands of dollars every minute that a malfunctioning product delays the OEM production line, not to mention the cost to replace the malfunctioning product itself. In addition, each test station typically requires a worker to manually power the product functions and connect the test equipment for each test station. If the system was completely automated, the number of workers for quality control can be reduced and the speed in which the products being tested can be increased, dramatically decreasing the operating expenses and increasing the throughput of the manufacturing facility.

[0018] The proposed wireless power system can provide power to products directly on assembly and production lines while wirelessly communicating test instructions to verify each product function.

[0019] FIG. 1 illustrates an example block diagram of the wireless power system. The transmitter module is electrically connected to an AC -DC charger plugged into an outlet at the industrial facility. The Transmitter Electronics include a voltage breakout PCB, a power amplifier, a matching network, and RF filters. In the voltage breakout PCB, there is a step-down converter for the amplifier digital logic and a boost converter for the amplifier input. The step-down converter for the amplifier digital logic can be a buck, flyback, or sepic converter. The voltage breakout PCB can also have reverse-polarity protection, EMI filters, fuse protection, and other forms of EMI, short circuit, and reverse-polarity protection circuitry. Furthermore, the voltage breakout PCB electronics can be integrated into other PCBs directly, such as the amplifier and matching network.

[0020] The power amplifier converts the DC signal to an AC signal (e.g., 85kHz, 100kHz, 6.78MHz, or 13.56MHz) and provides that to the Tx coil that is substantially resonating at the same frequency.

[0021] The power amplifier can be a switching amplifier, such as a series or parallel resonant or off-resonant Class D or Class E amplifier. Additionally, the power amplifier can be single-ended or differential and can comprise an isolated switching amplifier topology. Furthermore, it can have a wideband impedance matching network or a parallel-tuned amplifier matching network topology. In a wideband impedance matching network, the amplifier is matched for a wide range of load conditions. In a parallel-tuned power amplifier, the load network and matching network are tuned such that the Tx Coil is in parallel rather than in series to the resonant capacitor with the load network of the amplifier also tuned at the same resonant frequency. That is, the entire power amplifier network operates completely in resonance rather than using an off-resonant load network. In some embodiments, a transformer can also be included to further increase the oscillating voltage across the transmitter coil and thereby further improve the flux linkage and power delivery between the transmitter and receiver. Additionally, the parallel resonant power amplifier is often better protected from movements or changes in the position of the receiver or capacitive and inductive reflections from the surrounding environment that could cause a substantial change in the efficiency of the power amplifier. Some examples of a suitable poweramplifier are further disclosed in commonly owned US Patent Application Publication No. 2021 / 0359551, which is incorporated by reference herein.

[0022] When the presence of a product is detected, the communication (Comms) module in the transmitter verifies the line equipment test instructions and sends a wireless signal to the Comms unit in the Receiver Module to initiate the tests for that particular station. The Comms module can consist of a microcontroller (MCU) programmed for wired communication protocols, such as I2C, CAN, and / or LIN communication capabilities, and a wireless communication device, such as Bluetooth, Bluetooth Low Energy, LTE, WiFi, and 5G. Furthermore, the Comms modules for both the transmitter and the receiver can be integrated directly into the same PCB and / or electronic housing unit as the other transmitter and receiver electronics and is separated in the block diagram in FIG. 1 to better illustrate the communication process.

[0023] The transmitter’s detection of the product can be based on cameras or sensors (e.g., ultrasonic, laser-based, or capacitive-based sensors) or changes in electrical characteristics (e.g., reflected impedance back to the amplifier). The line equipment can be physically connected to the transmitter module (e.g., connector on a Tx Electronics PCB) to provide the test instruction for that station or can also have a separate Comms module electrically connected to the inputs and outputs of the line equipment harness. In this case, the Comms module on the line equipment can wirelessly communicate the test instructions to the amplifier and the results of that test can be wirelessly communicated back to the line equipment. This may be beneficial when the wiring harness between the line equipment and the transmitter is cumbersome to connect (e.g., the production facility layout requires a long and / or unreliable connection).

[0024] One or many Rx Coils either embedded directly in the product or on a pallet which holds the product on the production line couples significantly with the Tx Coil at each test station and provides that signal to the Receiver Electronics. The Receiver Electronics contain tuning and matching capacitors to substantially resonate at the same resonant frequency, an AC -DC converter (e.g., bridge rectifier) and aDC-DC converter (e.g., to regulate the output for each product function such as 5V, 12V, and 24V). In some embodiments, these converters can be consolidated into a single AC -DC converter with voltage output regulation.

[0025] The Receiver Comms module receives a signal from the Comms module in the transmitter or line equipment at each test station identifying the test procedure and enables the different functions via a power distribution unit (PDU). The PDU consists of electrical or electromechanicalswitches (e.g., BJT or MOSFET switches) that can disable and enable different loads for a multiload product.

[0026] For example, car seats and doors often have multiple motors for different user functions, such as mirror motors, window motors, and seat lateral motors. For testing these motors, the test equipment may want to monitor the current, voltage, and / or power for that function to verify that it is operating effectively for a certain duration of time, which also may vary depending on the type of function (e.g., a window motor is typically faster than a car seat motor).

[0027] After receiving the test instruction from the transmitter or directly from the line equipment, the microcontroller unit (MCU) in the Receiver Module can enable that function to be powered by controlling the switch(es) (e.g., pulling the gate signal high or low for the designated function with gate drivers) and if applicable review the status of that function. For example, the MCU can monitor the current or power being drawn via a current monitoring circuit or apply different test voltages for that function for the duration of time it is enabled. Furthermore, the Transmitter Comms module may want to verify memory or other data in the product. In this case, the MCU in the Receiver Module may need to enable the power for the product via the PDU and then communicate with the product directly (e.g., Electronic Control Units or Computers) via a wired protocol (e.g., CAN, LIN, or I2C) to verify memory or other product data. The Receiver Comms module can then provide all the applicable test data and product characteristics to the Transmitter Comms module or to a separate Comms module for the line equipment.

[0028] In some embodiments, it is possible that an inductive system rather than a resonant inductive system can be implemented whereby the charging distance for the application is short, and often fixed and repeatable to simplify the transmitter and receiver electronics and reduce the overall system cost. However, even for short distance, fixed, and repeatable locations, this may be difficult to implement when the products have multiple load conditions (e.g., multiple received power level requirements).

[0029] FIG. 2 illustrates an example conveyer belt of an assembly line for quality control stations. In this example, there are two quality control stations for simplicity: one at the beginning of the line and the second at the end of the line. There can be one station or many stations (e.g., 3, 4, 5, 6, 7 ... “N” where “N” is any number greater than 7) depending on the number of products that need to be tested and the number of tests that need to be performed. Furthermore, while the example illustration is for car seats, the system is applicable for a wide variety of electronicproducts, especially those with multiple loads or functions that need to be tested and verified. Some examples are car seats, car doors, center consoles, headphones, phones, tablets, computers, and displays.

[0030] FIG. 2 describes an example embodiment whereby the Transmitter Module powers and communicates directly with a Receiver Module embedded into the product itself. Specifically, the first and last car seats are receiving wireless power and test instructions indicated by the glowing circles 200. An embedded Receiver Module may be applicable for products that have existing wireless power receivers and communication modules. In this case, it can be more affordable to implement the wireless power system since the receivers are already integrated into the product, eliminating the need for additional receiver modules for testing and verification purposes.

[0031] There are also many embodiments in which powering a pallet or a device that physically holds the product as it moves across the line would be more appropriate. FIG. 3 is an illustration of the same car seat product mounted on a pallet 300. The Receiver Module mounted to the pallet can be helpful when there is not an existing Receiver Module embedded directly within the product itself or would be difficult to integrate directly. In this case, the Receiver Module is integrated into the pallet that holds the product and the product’s electrical connections are wired to the Receiver Module on the pallet when the product is initially mounted. The pallet can be a wide variety of different materials (e.g., wood, metal, or plastic). However, if the pallet is metal, the Transmitter and Receiver Module mounting locations should be carefully considered so that the metal does not significantly reduce the coupling between the Tx and Rx Coils.

[0032] FIG. 4 is a 2D illustration of the example wireless power and communication system shown in FIG. 2 and FIG. 3. In FIG. 4, the first test equipment (TE1) is electrically connected to the first transmitter (TX1) at the first test station. The first test station provides wireless power for the car seat product receiver module (Pl) to verify a single function (e.g., heater or motor). If Pl passes the exam, then it will continue to move along the line. If P l fails, then TX1 or TE1 can send a notification to a worker to remove Pl off the line for rework. P2 and P3 are car seat products that have already been tested and verified by TX1 and TE1 and are on transit to the second test station. Meanwhile, at the second test station, TE2 is electrically connected to TX2 to provide power and test instructions to the fourth car seat product receiver module (P4).

[0033] In some embodiments, the Transmitter Modules (e.g., TX1 and TX2) can entirely substitute the Test Equipment (e.g., TE1 and TE2) by programing the Transmitter Modules with the lineequipment test procedures along with parameters required to verify and categorize each product. In this embodiment, the factory can save additional expenditures by entirely replacing their existing test equipment with the transmitter modules themselves. In other embodiments, the test equipment can be consolidated to conduct multiple tests at one or many stations.

[0034] Furthermore, the mounting locations for the transmitters and receivers can vary depending on the available space on the line. For example, at some factories, there is cabling underneath the conveyer belt making it difficult or impossible to install Transmitter Modules underneath the conveyer belt. In this case, it may be beneficial to mount the Transmitter Modules for each respective station in a side mounted position as shown in FIG. 5 by TE1 and TE2 (Transmitter Module) and Pl and P4 (Receiver Module).

[0035] For the wireless power system, it is important that the Rx Coil (whether embedded into the product or on the pallet) is approximately parallel to the Tx Coil to significantly couple with one another. Therefore, for underneath mounted Transmitter Modules, the Receiver Module would likely be mounted directly underneath the product (e.g., car seat) or on the backside of the product (e.g., phone or tablet) approximately parallel to the Tx Coil position. Meanwhile, for side mounted Transmitter Modules, the Receiver Module would likely be mounted on the side of the product that is directly facing the Transmitter Module as shown in FIG. 5.

[0036] It is also possible that the Transmitter and Receiver Electronics are mounted in separate housing units from the Tx and Rx Coils. In this case, it is important that the Tx and Rx Coils continue to be positioned approximately parallel to one another, but the electronics can be positioned parallel, acutely, or orthogonally relative to the coils. Furthermore, the electronics can electrically connect directly to the coils via interlocking connectors in the housing or wiring (e.g., coax cables) can electrically connect them to improve the flexibility of the mounting locations. For separate coil and electronics modules, it is typically beneficial to include the tuning capacitors and potentially other matching components on a PCB in the coil modules so that changes in cabling and positioning do not significantly impact the coil tuning and matching for the electronics modules. Furthermore, for the Rx Coil, it may also be beneficial to integrate the AC -DC converter (e.g., bridge rectifier) as well.

[0037] By developing separate Tx and Rx Electronics and Coil modules, the electronics and coils can potentially be interchangeable and more readily serviceable. For example, at a factory, receiver product pallets can be interchanged with different electronics modules for testing differentprocedures for different products that can be mounted on the same pallet. This can occur during a product change in factory production. Furthermore, if there is an error with the coil or electronics module, the entire transmitter or receiver potentially wouldn’t need replacing, reducing reworking and part substitution costs. This can be further mitigated by separating different electrical subsystems (e.g., power amplifier, AC -DC converter, and PDU) into different modules as well.

[0038] FIG. 6 is a 2D diagram of the example wireless power and communication system in FIG. 4 with the capability of communicating test results with a database. In some embodiments, there are many transmitters in a single network or industrial environment to test and verify many products simultaneously (e.g., TX1, TX2, TX3. . ,TX(‘N’) where ‘N’ can be any number greater than 3). It may therefore be beneficial for each transmitter to send the information of each test result of each product to a database that can collect all verification testing results. This is indicated by the red thunderbolt in FIG. 6 and the information can be wirelessly communicated, such as WiFi, LTE, or 5G. This is especially helpful for instances in which there is no direct interfacing of the test equipment (e.g., TE1 and TE2) with the Transmitter Modules. Each transmitter can wirelessly send product, test procedure, results, and other performance metrics to the database for a manager to review. Furthermore, this database can be accessible to users online or through a mobile application.

[0039] The following technical solutions may be preferably adopted or implemented by some embodiments.

Alternatively, the test plan may test same functionality of all target test objects at a given time.
