Organization, Consolidation and Presentation of Financial Statements [Abstract]
General	General Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared by Teledyne Technologies Incorporated (Teledyne or the Company) pursuant to the rules and regulations of the Securities and Exchange Commission. Certain information and disclosures normally included in notes to consolidated financial statements have been condensed or omitted pursuant to such rules and regulations, but resultant disclosures are in accordance with accounting principles generally accepted in the United States as they apply to interim reporting. The condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and the notes thereto in Teledyne’s Annual Report on Form 10-K for the fiscal year ended January 1, 2012 (“2011 Form 10-K”). In the opinion of Teledyne’s management, the accompanying unaudited condensed consolidated financial statements contain all adjustments (consisting of normal recurring adjustments) necessary to present fairly, in all material respects, Teledyne’s consolidated financial position as of September 30, 2012 and the consolidated results of operations and consolidated comprehensive income for the third quarter and nine months then ended and the consolidated cash flows for the nine months then ended. The results of operations and cash flows for the periods ended September 30, 2012 are not necessarily indicative of the results of operations or cash flows to be expected for any subsequent quarter or the full fiscal year. Recent Accounting Pronouncements In July 2012, the Financial Accounting Standards Board ("FASB") issued new accounting guidance on the testing of indefinite-lived intangible assets for impairment. The guidance allows entities to first perform a qualitative assessment to determine the likelihood of an impairment for an indefinite-lived intangible asset and whether it is necessary to perform the quantitative impairment assessment currently required. This guidance is effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012, with early adoption permitted. The Company does not expect the adoption of this guidance to have a material impact on Teledyne's financial position, results of operations or cash flows. In 2011, the FASB issued new disclosure guidance related to the presentation of the Statement of Comprehensive Income. The new disclosure guidance requires an entity to present the total of comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. Teledyne adopted the new presentation requirement effective January 2, 2012. Teledyne elected the two-statement approach presenting other comprehensive income in a separate statement immediately following the condensed consolidated statements of income. In 2011, the FASB issued new accounting guidance that amends some fair value measurement principles and disclosure requirements. The new guidance provides a consistent definition and measurement of fair value, as well as similar disclosure requirements between U.S. GAAP and International Financial Reporting Standards. It also changes certain fair value measurement principles, clarifies the application of existing fair value measurement and expands the disclosure requirements, particularly for Level 3 fair value measurements. Teledyne’s adoption of these new provisions, effective January 2, 2012, did not have an impact on our financial position or results of operations.
