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 .
DETAILED ACTION
Claim Objections
Claim 3, 10, 15 and 19 are objected to because of the following informalities:
Claim 3 recites “ the sub-images” in line 4. It should be “ the multiple sub-images”.
Claim 10 recites the limitation “the data” in line 1. It should be “ the radar data”.
Claim 15 recites “each data section” in line 2. It should be “the each data section”.
Claim 19 recites the limitation “the radar system” in line 3. It should be “the mmWave radar system”.
Appropriate correction is required.
Claim Rejections - 35 USC § 112
The following is a quotation of 35 U.S.C. 112(b):
(b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention.
The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph:
The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention.
Claims 1-20 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention.
Claim 1 recites the limitation “radar data” in line 3. It is unclear if “radar data” refers to “radar data” in line 1 or something else.
Claim 1 recites the limitation "the centre" in 8, “the total” in line 12, “the shifting” in line 15. There is insufficient antecedent basis for this limitation in the claim.
Claim 3 recites the limitation “the end” in line 4, “the next” in line 5. There is insufficient antecedent basis for this limitation in the claim.
Claim 4 and claim 5 recite “performed iteratively until...” in line 1. It is unclear if claims refer back to “segmenting the image, generating shifted data, generating reduced data and shifting the reduced data are performed iteratively” in claim 3 or something else. If the claims refer back to step in claim 3, it needs to recite “wherein segmenting the image, generating shifted data, generating reduced data and shifting the reduced data are performed iteratively until…”.
Claims 4-6 are rejected based on rejection of claim 3.
Claim 7 recites the limitation “the radar”. It is unclear if the radar refers to the radar data or something else.
Claim 11 recites the limitation “the target’ in line 1, and “the radar system” in line 2. There is insufficient antecedent basis for this limitation in the claim.
Claim 11 also recites “approximately ” in line 2. The term “approximately” in claim 11 is a relative term which renders the claim indefinite. The term “approximately” is not defined by the claim, the specification does not provide a standard for ascertaining the requisite degree, and one of ordinary skill in the art would not be reasonably apprised of the scope of the invention.
Claims 2-11 rejected based on the rejected of claim 1.
Claim 12 recites the limitation “radar data” in line 3. It is unclear if “radar data” refers to “radar data” in line 1 or something else.
Claim 12 recites the limitation “the data segment” in line 10. There is insufficient antecedent basis for this limitation in the claim.
Claim 19 recites “ “the target” in line 2. There is insufficient antecedent basis for this limitation in the claim.
Claim 19 also recites “approximately ” in line 2. The term “approximately” in claim 19 is a relative term which renders the claim indefinite. The term “approximately” is not defined by the claim, the specification does not provide a standard for ascertaining the requisite degree, and one of ordinary skill in the art would not be reasonably apprised of the scope of the invention.
Claims 13-19 rejected based on the rejected of claim 12.
Claim 20 recites the limitation “radar data” in line 3. It is unclear if “radar data” refers to “radar data” in line 1 or something else.
Claim 20 recites the limitation “the centre” in line 9, “the total” in line 13, “the shifting” in line 17. There is insufficient antecedent basis for this limitation in the claim.
Note: No prior art found disclose or render obvious independent claims 1, 12 and 20.
Conclusion
The prior art made of record and not relied upon is considered pertinent to applicant's disclosure.
1. Xiao et al., U.S Patent Application Publication No.20030161443 –A fast method for divergent-beam backprojecion is proposed for generating an electronic image from a preprocessed divergent-beam sonogram, the sinogram being a collection of divergent beam projections. The method can include the following steps: subdividing the sinogram into multiple sub-sinograms; performing a weighted backprojection of said sub-sinograms, to produce multiple corresponding sub-images; and aggregating said sub-images to create the electronic image. The subdivision of the sinogram into sub-sinograms can be performed in a recursive manner. A dual of the proposed method provides a fast means for reprojecting an electronic image, i.e., generating a divergent-beam sinogram from the image.
2. Basu et al. U.S Patent No.7215731- a reprojection/backprojection technique and apparatus for carrying out such a technique provides a hierarchical solution to speeding-up reprojection and backprojection of tomographic images. In the context of reprojection, a tomographic image is divided into a series of subimages. Each subimage is shifted to the origin, projected at a reduced number of views, and then up-sampled and shifted back (in the sinogram space). The resulting sinograms are then combined to provide a single sinogram. This process is applied one or more times recursively. In the context of backprojection, the above steps are transposed such that a sinogram is divided into a series of subsinograms. The subsinograms are then shifted and decimated by a given decimation factor. The decimated subsinograms are then backprojected onto hexagonal tiles whereupon the tiles are composited into a final image.
