Office Action

§103
DETAILED ACTION Notice of Pre-AIA or AIA Status The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Response to Arguments Applicant has amended independent claim 1 and persuasively argued that the amended limitation is the same limitation of cancelled and previously objected to claim 6. Regarding independent claims 7 & 11, there are neither amendments made or arguments provided. Because independent claims 7 & 11 have not been amended and no arguments have been made addressing the 103 rejections, Examiner maintains the previous 103 rejections to independent claims 7 & 11 and all subsequent dependent claims. Claim Rejections - 35 USC § 103 In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action: A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made. The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows: 1. Determining the scope and contents of the prior art. 2. Ascertaining the differences between the prior art and the claims at issue. 3. Resolving the level of ordinary skill in the pertinent art. 4. Considering objective evidence present in the application indicating obviousness or nonobviousness. Claims 7-14 are rejected under 35 U.S.C. 103 as being unpatentable over Jamaludin et al (Jamaludin, Wan Shahmisufi Wan, et al. "Cost-effective microcontroller-based hardware-in-the-loop test equipment for testing vehicle instrument panel." 2017 IEEE 4th International Conference on Smart Instrumentation, Measurement and Application (ICSIMA). IEEE, 2017.) in view of Weiss et al (Weiss, Kevin, et al. "PHiLIP on the HiL: Automated multi-platform OS testing with external reference devices." ACM Transactions on Embedded Computing Systems (TECS) 20.5s (2021): 1-26.). Regarding Independent claim 7, Jamaludin teaches: A method of testing hardware devices using an integrated Hardware-In-the-Loop (HIL) system, the method comprising: receiving, by a microcontroller unit of the integrated HIL system (See Examiner amended Fig. 2 below wherein a microcontroller is mapped and indicated. See Section II.), test parameters required for testing a Device Under Test (DUT) (See Fig. 2 Element DUT. See Section II.) through a front panel of the integrated HIL system (See Examiner amended Fig. 2 below wherein the input is shown and highlighted.); decoding, by the microcontroller unit (See Examiner amended Fig. 2 below wherein there is a data path depicted from the PC through the HiL to the DUT with data transitions and transformations. See Section II.), the test parameters for determining a test functionality to be performed on the DUT (See Examiner amended Fig. 2 below. See Title, Abstract and body of paper wherein it discloses a test setup to determine the functionality of an instrument panel.); performing, by the microcontroller unit, the test functionality on the DUT (See Examiner amended Fig. 2 below. See Title, Abstract and body of paper wherein it discloses a test setup to determine the functionality of an instrument panel.) and generate a test outcome corresponding to the test functionality (See Examiner amended Fig. 2 below. See Table 2.); and output, by the microcontroller unit (See Examiner amended Fig. 2 below. See Table 2.), the test outcome on a display interface of the front panel (See Examiner amended Fig. 2 below. See title, Abstract and body of the paper. See PC display in figure 2. See Section II & V. See Table 2.). PNG media_image1.png 726 1306 media_image1.png Greyscale PNG media_image2.png 220 338 media_image2.png Greyscale Jamaludin does not explicitly teach: using one of a plurality of hardware abstraction layers, comprised in an automated test application interface of the microcontroller unit. Weiss teaches: using one of a plurality of hardware abstraction layers, comprised in an automated test application interface of the microcontroller unit (Title; Abstract; Introduction page 91:2 Step 1; Table 3 & elsewhere.). PNG media_image3.png 152 580 media_image3.png Greyscale It would have been obvious to one of ordinary skill in the art before the effective time of filing to apply the teachings of Weiss to the teachings of Jamaludin such that one would use one of a plurality of hardware abstraction layers, comprised in an automated test application interface of the microcontroller unit because developers “of IoT systems can easily access various hardware features and specific functions when relying on the hardware abstraction layer (HAL) and APIs of an OS for embedded devices. See Section 2.1 paragraph 1 lines 1-2 on page 91:4 of Weiss. Regarding claim 8, Jamaludin & Weiss teach all elements of claim 7, upon which this claim depends. Jamaludin teaches configuring a plurality of test modules in the microcontroller unit, wherein the plurality of test modules includes at least one of a DUT-specific evaluation board (See Examiner amended Fig. 2 below Element signal conditioning circuit.), an ethernet module, a Controller Area Network (CAN) module, an Analog-to-Digital Converter (ADC) module, a Digital-to-Analog Converter (DAC) module, a Pulse Width Modulation (PWM) module, a resistor bank module, Local Interconnect Network (LIN) module, a relay module and a digital I/O module in the, wherein the plurality of hardware abstraction layers of the automated test application interface is configured to correspond to the plurality of test modules. Regarding claim 9, Jamaludin & Weiss teach all elements of claim 8, upon which this claim depends. Jamaludin does not explicitly teach the plurality of hardware abstraction layers communicates with corresponding plurality of test modules through an abstract interface configured in the automated test application interface. Weiss teaches the plurality of hardware abstraction layers communicates with corresponding plurality of test modules through an abstract interface configured in the automated test application interface (Section 2.1 paragraph 1; Section 3.1 paragraph 1; & Table 3.). It would have been obvious to one of ordinary skill in the art before the effective time of filing to apply the teachings of Weiss to the teachings of Jamaludin such that the plurality of hardware abstraction layers communicates with corresponding plurality of test modules through an abstract interface configured in the automated test application interface because developers “of IoT systems can easily access various hardware features and specific functions when relying on the hardware abstraction layer (HAL) and APIs of an OS for embedded devices. See Section 2.1 paragraph 1 lines 1-2 on page 91:4 of Weiss. Regarding claim 10, Jamaludin & Weiss teach all elements of claim 7, upon which this claim depends. Jamaludin does not explicitly teach the test outcome comprises a plurality of log files generated while performing the test functionality and an indication of completion of testing of the DUT. Weiss teaches the test outcome comprises a plurality of log files generated while performing the test functionality and an indication of completion of testing of the DUT (Section 4.1 step 8 of list on page 91:6 & Section 6.2 paragraph 1 second to last line.). It would have been obvious to one of ordinary skill in the art before the effective time of filing to apply the teachings of Weiss to the teachings of Jamaludin such that the test outcome comprises a plurality of log files generated while performing the test functionality and an indication of completion of testing of the DUT because this is how most systems work. A program runs and directs measurements and outputs of sensors to be logged into files for analysis either later or in real time. Regarding Independent claim 11, Jamaludin teaches: A non-transitory computer-readable medium storing computer-executable instructions for testing hardware devices using an integrated Hardware-In-the-Loop (HIL) system, comprising: receiving test parameters required for testing a Device Under Test (DUT) through a front panel of the integrated HIL system (See Examiner amended Fig. 2 below wherein an Input is depicted and highlighted.); decoding the test parameters for determining a test functionality to be performed on the DUT (See Examiner amended Fig. 2 below wherein there is a data path depicted from the PC through the HiL to the DUT with data transitions and transformations. See Section II.); performing the test functionality on the DUT (See Examiner amended Fig. 2 below. See Title, Abstract and body of paper wherein it discloses a test setup to determine the functionality of an instrument panel.) and generate a test outcome corresponding to the test functionality (See Examiner amended Fig. 2 below. See Table 2 and Sections II & V.); and outputting the test outcome on a display interface of the front panel (See Examiner amended Fig. 2 below. See title, Abstract and body of the paper. See PC display in figure 2. See Section II & V. See Table 2.).
