As described in further detail below, control system 102 provides a user with an opportunity to perform repairs on brake system 104 with assistance and guidance from control system 102.

[0029] In various embodiments, vehicle 100 includes an automobile. Vehicle 100 can be any of a variety of different types of automobiles, e.g., such as a sedan, a van, a truck, or a sport utility vehicle (SUV), and in certain embodiments can be two-wheel drive (2WD) (i.e., rear-wheel drive or front-wheel drive), four-wheel drive (4WD), or all-wheel drive (AWD) and / or various other types of vehicles. In certain embodiments, vehicle 100 can also include a motorcycle or other transportation means, such as an airplane, a spacecraft, a ship, etc., and / or one or more other types of mobile platforms (e.g., robots and / or other mobile platforms).

[0030] Vehicle 100 includes a body 106 disposed on a chassis 108. Body 106 substantially encloses the other components of vehicle 100. Body 106 and chassis 108 can together form a frame. Vehicle 100 also includes a plurality of wheels 110. Each wheel 110 is rotatably coupled to chassis 108 near a respective corner of body 106 to facilitate the movement of vehicle 100. In one embodiment, vehicle 100 includes four wheels 110, although this can vary in other embodiments (e.g., for trucks and certain other vehicles).

[0031] The drive system 112 is mounted on the chassis 108 and drives the wheels 110, for example, via the axles 114. In some embodiments, the drive system 112 includes a propulsion system. In some exemplary embodiments, the drive system 112 includes a motor 116 (e.g., an internal combustion engine and / or an electric motor / generator coupled to its transmission). In some embodiments, the drive system 112 includes or is coupled to an accelerator pedal that receives input from the driver of the vehicle 100. In some embodiments, the drive system 112 is automatically controlled via the control system 102 (e.g., for an autonomous vehicle).

In various embodiments, the input includes requests and / or responses from the user as part of the maintenance management of the braking system 104, such as further described in more detail below in connection with Figure 2 the process 200.

[0040] In various embodiments, the drive sensor 152 obtains sensor data from or in relation to the drive system 112, such as the state of the motor 116 (e.g., whether it is off or on) and the current transmission gear of the vehicle 100 (e.g., park, reverse, neutral, drive, low gear), and the like.

[0041] In various embodiments, the wear sensor 153 obtains sensor data regarding wear measurements of one or more components of the braking system 104, such as the pads 128 and / or the rotors 126 of the braking system 104.

[0043] In various embodiments, during the maintenance management of the braking system 104, the height sensor 155 obtains sensor data regarding the height of the vehicle 100. In certain embodiments, the height sensor 155 includes, for example, a chassis height sensor (e.g., of the suspension system of the vehicle 100).

[0044] In various embodiments, during the maintenance management of the braking system 104, the tilt sensor 156 obtains sensor data regarding the tilt of the vehicle 100. In certain embodiments, the tilt sensor 156 includes one or more gyro-based sensors; however, in other embodiments, one or more other types of tilt sensors 156 may be utilized.

[0045] In various embodiments, the other sensors 157 may include one or more other sensors that can be utilized during the maintenance management of the braking system 104, such as, for example, speed sensors, accelerometers, weight sensors, and the like.

[0046] In various embodiments, the display 142 provides information from the control system 102 (e.g., the processor 160 further described below) to a user of the vehicle 100 (e.g., in certain embodiments, a driver or other user within the vehicle 100) according to instructions provided by the control system 102. In certain embodiments, the display 142 includes visual information, such as via a display screen within the vehicle 100. Also in certain embodiments, the display 142 may further include audio components, such as via one or more speakers of the vehicle 100. In various embodiments, the display 142 provides the user with information regarding the braking system 104, including issues related to maintenance management of the braking system 104, safety inspections, and procedures. Also in certain embodiments, the display 142 is further used to receive information from the user regarding the maintenance management of the braking system 104 (e.g., in certain embodiments in combination with the input sensor 151).

[0047] In certain embodiments, the transceiver 144 provides or facilitates communication between the control system 102 and a user of the vehicle 100 (e.g., in certain embodiments, a driver or other user who may be inside or outside the vehicle 100). In certain embodiments, the transceiver 144 transmits messages related to the braking system 104 to the user's electronic device (e.g., a smartphone, computer, laptop, smart wearable device, etc.), including issues related to maintenance management of the braking system 104, safety inspections, and procedures. Also in certain embodiments, the transceiver 144 further receives messages regarding the maintenance management of the braking system 104 from the user's electronic device. Thus, it will be understood that in various embodiments, communication between the control system 102 and the user may occur via the display 142, the transceiver, or both.

[0048] In various embodiments, the navigation system 146 obtains location information for the vehicle 100 and for the operation of the vehicle 100 and for planning and implementing a driving path of the vehicle 100. In certain embodiments, the navigation system 146 includes a satellite-based navigation system, such as the Global Positioning System (GPS). Also in certain embodiments, the navigation system 146 obtains information for planning a driving route of the vehicle 100 that optimizes the break-in of the braking system 104 after its maintenance, as well as other possible functions.

[0049] In various embodiments, the controller 148 is coupled to the sensor array 140 and receives sensor data therefrom. In various embodiments, the controller 148 is further coupled to one or more (and in certain embodiments also to each) of the display 142, the transceiver 144, and the navigation system 146 and / or other vehicle components. In various embodiments, the controller 148 controls the braking system 104 and its maintenance management (and various other functions in various embodiments), including as described below in connection withFigure 2 as further described in process 200.

[0050] In various embodiments, controller 148 includes a computer system (also referred to herein as computer system 148), and includes a processor 160, a memory 162, an interface 164, a storage device 166, and a computer bus 168. In various embodiments, controller (or computer system) 148 controls vehicle operations, including controlling automated vehicle functions as well as other vehicle control functions. In various embodiments, controller 148 provides these and other functions in accordance with Figure 2 the steps of process 200, including performing maintenance management of braking system 104 of vehicle 100 for vehicle 100.

[0051] In various embodiments, controller 148 (and in certain embodiments, control system 102 itself) is disposed within body 106 of vehicle 100. In one embodiment, control system 102 is mounted on chassis 108. In certain embodiments, controller 148 and / or control system 102 and / or one or more of its components may be disposed external to body 106, such as on a remote server, in the cloud, or in other devices that perform image processing remotely.

[0052] It should be understood that controller 148 may otherwise be different from Figure 1 the embodiments depicted therein. For example, controller 148 may be coupled to or otherwise utilize one or more remote computer systems and / or other control systems, such as as part of one or more of the aforementioned vehicle 100 devices and systems.

[0053] In the depicted embodiments, the computer system of controller 148 includes a processor 160, a memory 162, an interface 164, a storage device 166, and a bus 168. Processor 160 performs the computing and control functions of controller 148, and may include any type of processor or multiple processors, a single integrated circuit such as a microprocessor, or any suitable number of integrated circuit devices and / or circuit boards that work together to implement the functions of a processing unit. During operation, processor 160 executes one or more programs 170 contained within memory 162, and thus, controls the general operation of controller 148 and the computer system of controller 148, typically during the execution of processes described herein, such as Figure 2 process 200, and as further described hereinafter in connection therewith.

[0054] The memory 162 can be any suitable type of memory, including various types of non-transitory computer-readable storage media. In some examples, the memory 162 is located on and / or co-located with the processor 160 on the same computer chip. In the depicted embodiment, the memory 162 stores the program 170 described above and the stored values 172 (e.g., look-up tables, thresholds, map data, and / or other values regarding the service management of the braking system 104 of the vehicle 100).

[0055] The interface 164 allows communication with the computer system of the controller 148, for example, from a system drive and / or another computer system, and can be implemented using any suitable method and device.

[0057] The bus 168 is used to transfer programs, data, status, and other information or signals between the various components of the computer system of the controller 148. The bus 168 can be any suitable physical or logical means of connecting the computer system and components. This includes but is not limited to direct hardwired connections, fiber optics, infrared, and wireless bus technologies. During operation, the program 170 is stored in the memory 162 and executed by the processor 160.

[0058] It should be understood that although the exemplary embodiment is described in the context of a full - fledged computer system, those skilled in the art will recognize that the mechanisms of the present disclosure can be distributed as a program product with one or more types of non - transitory computer - readable signal - bearing media for storing the program and its instructions and effecting its distribution, such as a non - transitory computer - readable medium that bears the program and contains computer instructions stored therein for causing a computer processor (such as processor 160) to execute and implement the program.

[0059] Figure 2 is a flowchart of a process 200 for maintenance management of a braking system for controlling a vehicle according to an exemplary embodiment. In various embodiments, process 200 can be implemented in conjunction with Figure 1 vehicle 100, which includes a control system 102, a braking system 104, and other components.

[0060] As Figure 2 depicted, process 200 begins at step 202. In one embodiment, process 200 begins when vehicle 100 is being or has been operated, such as during or after a current vehicle drive. In certain embodiments, process 200 can also begin when a request (e.g., a notification) has been received that is related to vehicle 100 and particularly related to the braking system 104 of vehicle 100 (e.g., related to the desire or need to service the braking system 104 of vehicle 100). In various embodiments, the request can be obtained from Figure 1 sensor array 140 (e.g., from its wear sensor 153, including a need for service based on at least a predetermined amount of wear on one or more components of braking system 104) and / or from a user or other party (e.g., a specific request for service such as via input sensor 151, transceiver 144, and / or display 142). In one embodiment, once process 200 begins, the steps of process 200 are executed continuously.

[0061] Sensor data is obtained at step 204. In various embodiments, via Figure 1Each sensor of the sensor array 140 of the vehicle obtains sensor data related to the vehicle. In some embodiments, the sensor data of step 204 includes sensor information regarding an input from a user (e.g., via the input sensor 151); the state of the drive system 112, such as whether the motor 116 is off or on and the transmission gear for the drive system 112 (e.g., via the drive sensor 152); wear measurements of one or more components of the braking system 104 (such as the pads 128 and / or the rotors 126) (e.g., via the wear sensor 153); camera data regarding the current placement and orientation of the vehicle 100 (e.g., via the camera 154); the height of the vehicle 100, such as the chassis height (e.g., via the height sensor 155); the tilt of the vehicle 100 (e.g., via the tilt sensor 156), etc. Additionally, in various embodiments, additional information can also be obtained, such as from the transceiver 144 (e.g., including messages and inputs from the user regarding the maintenance management of the braking system 104) and / or from the navigation system 146 (e.g., regarding the current geographical location of the vehicle 100 and potential routes for running in the braking system 104 after maintenance, etc.).

[0062] In various embodiments, it is determined whether a braking system request (e.g., notification) has been received (step 206). In various embodiments, this determination is made by the processor 160 based on the sensor data of step 202 and / or other information (e.g., communication). For example, in some embodiments, during step 206, when Figure 1 the wear sensor 153 provides sensor data indicating that one or more components of the braking system 104 (such as the pads 128 and / or the rotors 126) have experienced a sufficient amount of wear such that replacement is required, the braking system notification (or request) will be characterized as having been received. As an example, also in some embodiments, when the control system 102 receives an input from a user or other third party (e.g., via Figure 1 the input sensor 151 and / or the transceiver 144) that desires and / or requires maintenance of the braking system 104, the braking system notification (or request) will also be characterized as having been received.

[0063] In various embodiments, if it is determined in step 206 that a braking notification (e.g., request) has not been received, the process returns to step 204, and then steps 204 - 206 continue until it is determined during an iteration of step 206 that a braking notification has been received. Also in various embodiments, once it is determined during an iteration of step 206 that a braking notification (e.g., request) has been received, the process proceeds to step 208 described directly below.

[0064] In various embodiments, during step 208, brake system management maintenance is provided. Specifically, in certain embodiments, the control system 102 provides a notification to the user (e.g., via a display 142 inside the vehicle, or via an electronic message sent to the user's electronic device through the transceiver 144, or both), the notification provides brake system management maintenance, and seeks a response from the user to confirm whether the user desires to utilize the brake system management maintenance.

[0065] In various embodiments, it is determined whether management system entry has occurred for the brake system (step 210). In various embodiments, a processor (such as Figure 1 processor 160) determines whether the user has provided an input (e.g., via the display 142 of the vehicle 100 and / or via the user's electronic device received through the transceiver 144) indicating that the user desires to utilize the management system to service the brake system 104.

[0066] In various embodiments, if it is determined in step 210 that management system entry has not occurred (e.g., if the user has not provided an input for management maintenance to effect repair of the brake system 104), the process returns to step 208, and steps 208 - 210 are repeated thereafter until it is determined in an iteration of step 210 that management system entry has occurred. Also in various embodiments, once it is determined in an iteration of step 210 that management system entry has occurred (e.g., when the user has provided an input for management maintenance to effect repair of the brake system 104), the process proceeds to step 212 described below.

[0067] In various embodiments, during step 212, a safety check is performed. In various embodiments, the safety check is performed using information obtained via sensors of the sensor array 140 by Figure 1 processor 160, and in certain embodiments also using information obtained via user input (e.g., via Figure 1 the transceiver 144, display 142, and / or input sensor 151). In certain embodiments, the safety check includes the following, among other possible safety checks: (i) the lift status of the vehicle 100; (ii) whether wedges are used on both sides of the wheel 110; (iii) the status of the drive system 112 (e.g., whether the vehicle 100 is in a park transmission gear); (iv) whether the motor 116 of the vehicle 100 is off; and (v) whether the tilt of the vehicle 100 is within an acceptable range (e.g., such that the tilt does not exceed a predetermined value stored in the memory 162 as one of the stored values 172).

[0068] In various embodiments, these values are via Figure 1obtained by the sensor array 140, such as via a chassis height sensor 155 (e.g., regarding the lift status), a camera 154 (e.g., regarding the lift status, the use of wedges, and / or other parameters), an inclinometer 156 (e.g., regarding the tilt of the vehicle 100), a drive sensor 152 (e.g., regarding the transmission gear and whether the motor 116 is off), and other possible sensors, and / or via an input sensor 151, a display 142, and / or a transceiver 144 (e.g., regarding user input related to whether the vehicle 100 is ready for servicing the brake system 104, and / or regarding input related to one or more other parameters, such as whether the vehicle 100 is lifted, whether wedges are utilized, whether the motor 116 is off, whether the vehicle 100 is in a park transmission gear, etc.).

[0069] In various embodiments, it is determined whether the vehicle 100 is ready for servicing the brake system 104 (step 214). In various embodiments, this determination is made by Figure 1 the processor 160 based on the safety check of step 212. Specifically, in various embodiments, when all of the following conditions are met, the vehicle 100 is determined to be ready for servicing the brake system 104, namely: (i) the vehicle 100 is properly lifted; (ii) wedges are used on both sides of the wheels 110; (iii) the vehicle 100 is in a parked state; (iv) the motor 116 of the vehicle 100 is off; and (v) the tilt of the vehicle 100 is within an acceptable range.

[0070] In various embodiments, if it is determined in step 214 that the vehicle 100 is not ready for servicing the brake system 104, then one or more actions are performed (step 216). In various embodiments, the actions of step 216 include issuing a notice and instructions to the user of the vehicle 100 (e.g., to the owner of the vehicle 100, the individual servicing the vehicle 100, etc.) to perform certain steps so that the vehicle 100 will then be ready for servicing the brake system 104. For example, in various embodiments, Figure 1 the processor 160 can provide instructions for such notice and instructions via the display 142 and / or via the transceiver 144 (e.g., via communication sent to the user's electronic device) so that the user performs any required steps that have not been performed prior to servicing the brake system 104, such as: (i) lifting the vehicle; (ii) placing wedges on both sides of the wheels 110; (iii) putting the vehicle 100 in a park transmission gear; (iv) turning off the motor 116; (v) adjusting the tilt of the vehicle 100, etc. In certain embodiments, such corrective actions can also be automatically performed via instructions provided by the processor 160 to one or more other vehicle components (e.g., such as turning off the motor 116, shifting the drive system 112 to a park gear or mode, etc.).

[0071] In various embodiments, once an action is taken in step 216, the process then returns to step 212 for subsequent safety checks and then returns to step 214 to subsequently determine whether vehicle 100 is ready for repair of braking system 104. In various embodiments, steps 212 - 216 are repeated in this manner until it is determined during an iteration of step 214 that vehicle 100 is ready for repair of braking system 104.

[0072] In various embodiments, once it is determined during an iteration of step 214 that vehicle 100 is ready for repair of braking system 104, a selection of a desired corner and / or axle for repair of braking system 104 is provided to the user (step 218). Specifically, in various embodiments, options regarding which of the desired wheels 110 are to be used for brake repair are presented to the user. For example, in various embodiments, the user can select for repair of braking system 104 regarding the front axle 114, the rear axle 114, or both, or regarding which corner wheel 110 (e.g., wheels 110 on the front driver side, front passenger side, rear driver side, and / or rear passenger side, etc.) brake repair is desired.

[0073] In various embodiments, it is determined whether a user selection has been made (step 220). Specifically, in various embodiments, processor 160 determines whether the user has made a selection in response to the selection provided during step 218, such as via user input (e.g., via a direct interface with vehicle 100 and / or via a message sent through the user's electronic device) via display 142, input sensor 151, and / or transceiver 144.

[0074] In various embodiments, if it is determined in step 220 that the user has not made a selection, the process returns to step 218. In various embodiments, steps 218 and 220 are then repeated in various iterations until it is determined during an iteration of step 220 that a user selection has been made. In various embodiments, once it is determined during an iteration of step 220 that a user selection has been made, the process proceeds to step 222 described below.

[0075] In various embodiments, during step 222, an identification of a first corner for brake repair is made (step 222). In various embodiments, this identification is made by Figure 1 processor 160 based on the user selection determined in step 220. In various embodiments, the identification of step 222 includes the specific wheel 110 of vehicle 100 for initiating brake repair.

[0076] In various embodiments, one or more initial repair actions are initiated (step 224). Specifically, in certain embodiments, the processor 160 provides instructions for one or more steps to be automatically performed to initiate brake repair for a selected wheel 110 (or corner) of the vehicle 100. In various embodiments where the repair includes replacing the brake pad 128, the processor 160 provides instructions to the motor 130 to automatically move the corresponding piston 132 away from the brake pad 128, such as by automatically and electronically retracting the piston 132, thereby facilitating the removal of the brake pad 128. In various embodiments, these instructions are then automatically executed by the motor 130. In certain embodiments, the instructions (and their implementation) may also include the movement of the piston 132 and / or the caliper assembly 124 to facilitate the removal of the brake rotor 126, and so on.

[0077] In various embodiments, once the initial repair action of step 224 is performed, subsequent communication is provided to the user (step 226). Specifically, in various embodiments, information and guidance are then provided to the user and the next step for repairing the brake system 104 of the specific wheel 110 (e.g., corner) of the vehicle 100 that is currently being processed is indicated. For example, in certain embodiments, the user is instructed to replace the brake pad 128 of the specific wheel 110 (or corner) of the vehicle 100 (e.g., now that the piston has been successfully retracted and is out of the way). In certain embodiments, the user may be instructed to take one or more other repair actions, such as replacing the brake rotor 126 of the specific wheel 110 (or corner) of the vehicle 100.

[0078] In various embodiments, it is determined whether the repair of the specific wheel 110 (or corner) is complete (step 228). Specifically, in certain embodiments, the determination regarding the requested action (such as replacing the brake pad 128 and / or the rotor 126) with respect to the specific wheel 110 being processed is made by Figure 1 the processor 160. In certain embodiments, this determination may be made via one or more prompts made to the user and corresponding inputs received from the user (e.g., confirmation that the action has been taken). In certain embodiments, sensor data (e.g., via Figure 1 one or more cameras 154) may also be used.

[0079] In various embodiments, if it is determined that the repair of the specific wheel is not complete, the process returns to step 226 and further communication with the user is performed as needed. In various embodiments, steps 226 and 228 are repeated in various iterations thereafter until it is determined during an iteration of step 228 that the repair of the specific wheel 110 being processed is complete. In various embodiments, once it is determined during an iteration of step 228 that the repair of the specific wheel 110 being processed is complete, the process then proceeds to step 230 described below.

[0080] In various embodiments, during step 230, it is determined whether a repair action has been performed on each of the wheels 110 selected by the user for brake repair. In various embodiments, this determination is made by Figure 1 processor 160.

[0081] In various embodiments, if it is determined in step 230 that a repair action has not been performed on one or more of the wheels 110 selected by the user for brake repair, the process proceeds to step 231. In various embodiments, during step 231, Figure 1 processor 160 identifies the subsequent wheels 110 (or corners) of vehicle 100 for repair. Specifically, in various embodiments, during step 231, processor 160 selects one of the wheels 110 that were initially selected by the user for brake repair (i.e., in steps 218 - 220) but for which the repair has not been completed (i.e., in steps 222 - 228). In various embodiments, when the repair begins on the subsequently identified wheel 110 (or corner) in step 231, the process then proceeds to step 222 above. In various embodiments, steps 222 - 231 are repeated in this manner in various iterations until it is determined in an iteration of step 230 that a repair action has been completed on each of the wheels 110 selected by the user for brake repair.

[0082] In various embodiments, once it is determined during an iteration of step 230 that a repair action has been completed on each of the wheels 110 selected by the user, the process then proceeds to step 232 as described below.

[0083] In various embodiments, during step 232, the post - repair route is completed. Specifically, in certain embodiments, during step 232, a post - repair safety check is performed and the brake pad clearance is set to the driving position. In various embodiments, this is performed according to instructions provided by Figure 1 processor 160. In various embodiments, the process then proceeds to step 233 described below.

[0084] In various embodiments, during step 233, one or more routes are selected to break in the newly repaired brake system 104. Specifically, in various embodiments, Figure 1 processor 160 selects one or more optimized driving routes for vehicle 100 that promote the best break - in of the brake system 104 (e.g., using the newly replaced pads 128 and / or rotors 126). In various embodiments, processor 160 combines Figure 1 with navigation system 146 (and combines with what is stored in Figure 1select an optimized driving route based on map data stored as the value 172 therein in the memory 162, including a driving route selected based on a route having a desired speed limit range and / or a number and / or frequency of desired stop signs, stop lights, etc., which may be desirable in order to provide optimal break-in for the life and performance of the newly repaired braking system 104.

[0085] In some embodiments, the processor 160 and / or the navigation system 146 may first receive from the user a desired driving destination of the vehicle 100 and may subsequently select an optimized route to the destination while also providing a break-in feature for the braking system 104. As an example, instead of selecting a route to the destination based on the shortest distance or shortest driving time, the processor 160 may alternatively select an optimized alternative route to the destination based on a desired speed limit range and the number and / or frequency of stop lights, stop signs, etc., in order to facilitate optimized break-in of the newly repaired braking system 104.

[0086] In various embodiments, the selected route (step 234) is implemented. Specifically, in various embodiments, one or more optimized break-in routes of step 233 are implemented during step 234. In some embodiments (e.g., where the vehicle 100 includes an autonomous vehicle 100), the processor 160 provides instructions to other vehicle components (e.g., the drive system 112, the steering system 118, and the braking system 104) to drive itself along one or more optimized break-in routes (e.g., via automatic acceleration, steering, braking, etc. directed by the processor 160). Alternatively, in other embodiments, the processor 160 provides a recommendation to the user regarding the optimized break-in route (e.g., via the display 142, via the navigation system 146, and / or via the transceiver 144 to the user's electronic device) for the user to implement (e.g., as indicated by a map provided via the navigation system 146, the display 142, and / or transmitted via the transceiver 144 to the user's electronic device, etc.).

[0087] In various embodiments, the process 200 then terminates (step 236).

[0088] Accordingly, methods, systems, and vehicles for performing brake repair management for a braking system of a vehicle are provided. Specifically, in various embodiments, a control system (including a processor) of the vehicle provides an opportunity for a user (such as an owner of the vehicle or a mechanic who will perform brake repair on the vehicle) to facilitate brake system repair management. For example, in various embodiments, the processor performs various sensor checks based on sensor data and / or communication with the user, and automatically initiates brake repair through one or more initial steps (such as instructing a motor of a caliper to retract a piston electronically to facilitate replacement of brake pads and / or brake rotors). Also in various embodiments, the processor further provides guidance to the user to perform one or more additional repair steps (such as replacing brake pads and / or rotors) after performing the initial steps according to the instructions provided by the processor. Additionally, in some embodiments, the processor can also work with a navigation system of the vehicle to plan and, in some embodiments, implement an optimized break-in route for vehicle travel to optimize the break-in of a newly repaired braking system. It should be noted that while these techniques can be implemented in conjunction with a brake-by-wire system, various of these techniques can also be implemented in different embodiments via one or more other different types of braking systems.

[0089] It should be understood that the systems, vehicles, and methods can be different from those depicted in the figures and described herein. For example, Figure 1 the vehicle 100, its control system 102 and braking system 104, and / or Figure 1 the components thereof can vary in different embodiments. Similarly, it should be understood that the steps of process 200 can be different from Figure 2 those depicted in Figure 2 and / or various steps of process 200 can occur simultaneously and / or in an order different from the order depicted in
