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 .
Priority
Receipt is acknowledged of certified copies of papers required by 37 CFR 1.55.
Drawings
The drawings are objected to under 37 CFR 1.83(a). The drawings must show every feature of the invention specified in the claims. Therefore, the “memory” recited in both claims 6 and 13 must be shown or the feature(s) canceled from the claim(s). No new matter should be entered. Corrected drawing sheets in compliance with 37 CFR 1.121(d) are required in reply to the Office action to avoid abandonment of the application. Any amended replacement drawing sheet should include all of the figures appearing on the immediate prior version of the sheet, even if only one figure is being amended. The figure or figure number of an amended drawing should not be labeled as “amended.” If a drawing figure is to be canceled, the appropriate figure must be removed from the replacement sheet, and where necessary, the remaining figures must be renumbered and appropriate changes made to the brief description of the several views of the drawings for consistency. Additional replacement sheets may be necessary to show the renumbering of the remaining figures. Each drawing sheet submitted after the filing date of an application must be labeled in the top margin as either “Replacement Sheet” or “New Sheet” pursuant to 37 CFR 1.121(d). If the changes are not accepted by the examiner, the applicant will be notified and informed of any required corrective action in the next Office action. The objection to the drawings will not be held in abeyance.
Claim Objections
Claims 2-6, 8, and 10-13 are objected to because of the following informalities:
2. (Proposed Amendment) The method according to claim 1, wherein the connection phase is a phase in which the signal receiver receives signals from a signal transmitter
4. (Proposed Amendment) The method according to claim 3, wherein the search program executed by the second electronic device each time when the first electronic device is connected to the signal receiver via one of the preset transmission channels includes processes of:
switching the clock recovery circuit with the second electronic device for providing the sampling phase to the analog-to-digital converter, and sequentially selecting, by the second electronic device, one of a plurality of preset phases as the sampling phase to be provided to the analog-to-digital converter;
configuring the first electronic device to transmit an analog transmission signal;
determining whether or not the signal receiver receives the analog reception signal;
using, in response to determining that the signal receiver receives the analog reception signal, the preset phase that is currently provided to the analog-to-digital converter as a phase zero;
resetting the equalizer coefficient of the target digital equalizer; configuring the target digital equalizer to perform an automatic update of the equalizer coefficient;
determining whether or not the equalizer coefficient of the target digital equalizer achieves coefficient convergence; and
recording, in response to determining that the equalizer coefficient of the target digital equalizer achieves the coefficient convergence, a signal-to-noise ratio and a coefficient convergence value of the target digital equalizer in the preset phase that is currently provided to the analog-to-digital converter.
8. (Proposed Amendment) The system according to claim 7, wherein the connection phase is a phase in which the signal receiver receives signals from a signal transmitter
11. (Proposed Amendment) The system according to claim 10, wherein the search program executed by the second electronic device each time when the first electronic device is connected to the signal receiver via one of the preset transmission channels includes processes of:
switching the clock recovery circuit with the second electronic device for providing the sampling phase to the analog-to-digital converter, and sequentially selecting, by the second electronic device, one of a plurality of preset phases as the sampling phase to be provided to the analog-to-digital converter;
configuring the first electronic device to transmit an analog transmission signal;
determining whether or not the signal receiver receives the analog reception signal;
using, in response to determining that the signal receiver receives the analog reception signal, the preset phase that is currently provided to the analog-to-digital converter as a phase zero;
resetting the equalizer coefficient of the target digital equalizer;
configuring the target digital equalizer to perform an automatic update of the equalizer coefficient; determining whether or not the equalizer coefficient of the target digital equalizer achieves coefficient convergence; and
recording, in response to determining that the equalizer coefficient of the target digital equalizer achieves the coefficient convergence, a signal-to-noise ratio and a coefficient convergence value of the target digital equalizer in the preset phase that is currently provided to the analog-to-digital converter.
Claims 3, 5, and 6 depend either directly or indirectly from claim 2, therefore they are also objected.
Claims 10, 12, and 13 depend either directly or indirectly from claim 8, therefore they are also objected.
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 1-13 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 (lines 14-15 and 15), claim 2 (lines 5, 11, 11-12, and 12), claim 4 (lines 15 and 25), claim 5 (lines 10 and 12), claim 6 (lines 7, 8-9, 9, 10, 12, 13, 13-14, 15, and 16), claim 7 (lines 18-19 and 19), claim 8 (lines 5, 11, 11-12, and 12), claim 11 (lines 15 and 25), claim 12 (lines 10 and 12), and claim 13 (lines 7, 8-9, 9, 10, 12, 13, 13-14, 15, and 16), the phrases “the coefficient initial value”, “the coefficient limit value”, “the preset transmission channel”, “the preset phase”, and “the coefficient convergence values” all lack antecedent basis. Clarification is required since the independent claims 1 and 7 recite “a plurality of preset transmission channels”, “a plurality of coefficient initial values”, and “a plurality of coefficient limit values” and claims 4 and 11 recite “a plurality of preset phases” and “a coefficient convergence value”.
Claim 3 depend from claim 2, therefore it is also rejected.
Claim 9 depend from claim 7, therefore it is also rejected.
Claim 10 depend from claim 8, therefore it is also rejected.
Allowable Subject Matter
Claims 1-13 would be allowable if rewritten or amended to overcome the rejection(s) under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), 2nd paragraph, set forth in this Office action.
Claims 2-6 and 8-13 would be allowable if rewritten or amended to overcome the objection(s) set forth in this Office action.
Conclusion
The prior art made of record and not relied upon is considered pertinent to applicant's disclosure.
Zerbe et al.
