Response to Amendment
The objections to the claims are now withdrawn in light of the claim amendments.
Response to Arguments
On page 9 of the Amendment, to distinguish the amended limitation reciting “wherein the control circuitry is centralized such that the processing is non-distributed”, the following is argued:
Kane describes a system fundamentally based on a distributed architecture, where a main unit (“host”) communicates with multiple remote sensor modules or “sender units” (“clients”), each of which may have their own processing circuitry. See Kane, [0032]-[0033], Figs. 2, 7, 8, 9. The sender units act as clients in a host/client distributed control system, and Kane explicitly supports multiple configurations, including “host/client” and “host/host” arrangements, with data being transmitted between distributed devices. While Kane describes a “handheld central or main field test and measurement instrument” ([0023]), the main unit is specifically designed to receive data from distributed sender units that may themselves include processing circuitry ([0033], [0038]). The main unit in Kane is not responsible for all processing; rather, it aggregates data from distributed sources, and the sender units may perform their own signal conditioning, processing, or communication tasks before transmitting data to the main unit.
In contrast, the present application is directed to a self-contained measurement system in which all control, processing, and data handling is performed by centralized control circuitry housed within the main unit. The sensors are electrically connected to this main unit, and all user interaction, data selection, logging, and transmission are managed by the centralized control circuitry within the device housing. There are no distributed processing elements or reliance on external sender/client units for processing or control. The claims of the present application require that the control circuitry is centralized such that the processing is non-distributed, the control circuitry.
The Office Action asserts that Kane's main unit includes “control circuitry disposed within the housing” ([0054]), but this is not sufficient to meet the amended claims. In Kane, the control circuitry in the main unit is only one part of a distributed system, and much of the signal processing, data acquisition, and communication may occur in the remote sender units ([0033], [0038], [0041]). The main unit in Kane is not responsible for all processing, nor is the system self-contained. It would not have been obvious to reconfigure Kane as a centralized non- distributed system because Kane repeatedly emphasizes the flexibility of its distributed architecture, allowing for various combinations of sender units, wireless and wired communication, and modular expansion ([0032], [0038], [0041], [0057]-[0063]). Kane is specifically and intentionally design as a modular, distributed system with multiple sender units and a main unit that aggregates data from distributed sources. The architecture, operation, and intended use of Kane's system are fundamentally different from the self-contained, centralized system now claimed.
However, the Office respectfully disagrees. Kane describes in paragraph [0038] that “Preferably, each of the sender units 204 include circuitry adapted to permit wireless transmission of sensor information characterizing sensor inputs 202 for wireless reception by circuitry incorporated in the main unit 120 for wirelessly receiving the sensor information from the sender units 204.” (emphasis added) Also, paragraph [0040] of Kane explains that “Each kit preferably includes the appropriate probes, sensor attachments, wiring leads, cabling, sensor signal senders/transmitters, transceivers/receivers (if needed) for attachment to the main unit 120, and other equipment and circuitry for physically taking the desired system measurement (i.e. suction line pressure) and providing sensed measurement signal information (referred to as sensor inputs) receivable by the main unit 120 sensor inputs 122.” (emphasis added) Paragraph [0046] provides that “The E-kit 412 may substantially comprise the functionality and features of a digital multi-meter combined with circuitry adapted to provide test and measurement information to the main unit 120 via sensor inputs 122.” (emphasis added)
Contrary to the arguments presented in the Amendment, there is no distributed processing being performed in Kane. Clearly, the sensor information is not processed at the sender units or any of the sensor kits. The sensor data or sensor signals are received and processed at the main unit; thus, functioning as a “centralized…non-distributed” processing circuitry. In addition to the portions of Kane referred to in the Final Office Action dated August 27, 2025, Kane also describes in paragraph [0048] describes that “The main unit 120 preferably automatically monitors (step 510) the sensor inputs 122 for settled/steady state sensor measurement information and alerts the technician (visually, audibly, and/or tactilely) of the status of the connected sensors, status of the system 100 (for example, the settling of subcool or superheat measurements following a change in refrigerant charge, the presence of hazardous gas concentrations near the furnace warranting improved ventilation, whether the sensed measurement information is within typical/expected operating ranges), and the status of analysis or tests in-process or to be performed (for example, the status of data-logging).” (emphasis added) In addition, paragraph [0056] of Kane provides that “Microprocessor 620 and supporting circuitry preferably provides the main unit 120 with processing means for executing stored programming instructions, access to on-board and accessible databases and memory, calculations, execution of algorithms, and other computing needs. Additional processing capacity 640 is preferably included for real-time monitoring and display of input data, preferably real-time monitoring of all inputs simultaneously or substantially simultaneously.” (emphasis added)
The main unit is described as a microprocessor that receives sensor inputs and monitors such inputs to then alert a technician of the status of the sensor and the system, and the status of analysis or tests in-process or to be performed. The main unit functions as a centralized microprocessor. Kane does not describe that the sensor unit are processing the information and that the main unit is simply displaying information. A person of ordinary skill in the art would appreciate that the description of Kane provides a centralized processing main unit.
In addition, in another embodiment, paragraph [0058] of Kane provides that a sensor interface may be included to receive the sensor signals and transmitted to “a user interface 708 such as a field portable tablet computing device, netbook, or smartphone device which can receive the transmitted sensor information and perform the data processing and user interface and feedback capabilities described herein provided by the main unit 120”, which further clarifies that the processing is performed at a user interface provided by the main unit; thus, teaching that the main unit is “centralized”.
Therefore, in light of the various descriptive portions of the cited reference, Kane teaches a main unit that includes a control circuitry that is “centralized such that the processing is non-distributed” and the arguments provided in the Amendment are not deemed persuasive. The prior art rejection of independent claims 1, 13, and 20 and related dependent claims are maintained.
