Office Action

§102
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 . Claim Rejections - 35 USC § 102 The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – (a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention. (a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention. Claim(s) below is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Tuo (WO2018216349). Referring to claims 1 and 13, Tuo shows a detection method and system (see figure 22), performed by a detection system (see the detection system shown in figure 20) comprising a light emitting module (see the light emitting module shown in figure 21 Ref 110,) a processing module and a light receiving module (see the processing module shown in figure 20 Ref 130), the light emitting module comprising N emitting regions, wherein N is an integer greater than or equal to 2 (see figure 21 Ref 110 note the emitter blocks), lights respectively emitted from every two adjacent emitting regions among the emitting regions having different polarization angles (see figure 21 Ref 110 and the blown up figure of 112 note the polarization angles as shown), the light receiving module comprising N receiving regions respectively corresponding to the N emitting regions in the light emitting module (see figure 21 Ref 120 and the blown up figure of Ref 121), every two adjacent receiving regions among the receiving regions receiving a light returned from a detected object at different polarization angles (see figure 21 Ref 120 and the blown up figure of Ref 121), the detection method comprising: receiving, by at least some of the receiving regions in the light receiving module in at least part of a time period, the return light reflected by the detected object with different polarization angles that is outputted by at least two emitting regions (see step S101 and S102 where a reference value as acquired and compared to a return value); generating a photogenerated electrical signal by the light receiving module under excitation of the return light with at least one of the polarization angles after being partially or fully filtered, corresponding to at least a part of a region of the return light with different polarization angles (see step S102-S103 where the object is detected based on the polarized return light that is filtered by the light receiving unit and the detection is output); and processing, by the processing module, the photogenerated electrical signal generated by the light receiving module under the excitation of the return light after being filtered, to obtain final target information of the detected object (see step S105 where when a transparent object is detected the residual stress detection in the object is performed). Referring to claims 2 and 14, Tuo shows the detection system further comprises a polarization module arranged upstream of the light receiving module in a direction of the return light, the polarization module comprises N polarization filtering regions respectively corresponding to the N emitting regions in the light emitting module, and wherein the (note the polarizing plate/filter as shown in the receiving unit Ref 120) method further comprises: receiving, by at least one of the polarization filtering regions of the polarization module in the at least part of the time period, the return light reflected by the detected object with different polarization angles that is outputted by the at least two emitting regions, wherein the at least one polarization filtering region is used to partially or fully filter the return light with the at least one polarization angle, and the light receiving module receives the return light after being filtered by the polarization module and outputs the excited photogenerated electrical signal (see the flowchart shown in figure 23 that specifically determines the presence of a transparent object based on the filtered polarizations). Referring to claims 3 and 15, Tuo shows the emitting lights of the N emitting regions correspond to regions in a view field, and two emitting lights at least partially adjacent have an overlapping region (see the emission FOV as shown in figure 21 Ref 110). Referring to claims 5 and 17, Tuo shows the some receiving regions among the N receiving regions receive a light with at least two different polarization angles returned by the detected object (see figure 21 Ref 120 note the RGB detection regions). Referring to claims 10 and 22, Tuo shows N is an even number greater than or equal to 2 (see figure 21). Allowable Subject Matter Claims 4, 6-9, 16 and 18-21 objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims. Conclusion Any inquiry concerning this communication or earlier communications from the examiner should be directed to LUKE D RATCLIFFE whose telephone number is (571)272-3110. The examiner can normally be reached M-F 9:00AM-5:00PM EST. Examiner interviews are available via telephone, in-person, and video conferencing using a USPTO supplied web-based collaboration tool.
