	Goodwill at September 27, 2014, in our Medical Devices reporting unit, is net of a $38,200 accumulated impairment loss. Certain factors, including industry conditions and the future profitability of our business might have a negative impact on the carrying value of our goodwill and we may incur additional goodwill impairment charges.

	All acquired intangible assets other than goodwill are being amortized. Customer-related intangible assets primarily consist of customer relationships. Program-related intangible assets consist of long-term programs represented by current contracts and probable follow on work. Technology-related intangible assets primarily consist of technology, patents, intellectual property and software. Marketing-related intangible assets primarily consist of trademarks, trade names and non-compete agreements.
	Amortization of acquired intangible assets was $6,660 for the three months ended January 3, 2015 and $7,563 for the three months ended December 28, 2013.

	Lines of credit	415		3,660
	Short-term borrowings	$	100,415	$	103,660
	The Securitization Program matures on February 13, 2015 and effectively increases our borrowing capacity by up to $100,000. Under the Securitization Program, we sell certain trade receivables and related rights to an affiliate, which in turn sells an undivided variable percentage ownership interest in the trade receivables to a financial institution, while maintaining a subordinated interest in a portion of the pool of trade receivables. The Securitization Program can be extended by agreement of the parties thereto for successive 364-day terms. Interest for the Securitization Program is based on prevailing market rates for short-term commercial paper plus an applicable margin. A commitment fee is also charged based on a percentage of the unused amounts available and is not material. The agreement governing the Securitization Program contains restrictions and covenants which include limitations on the making of certain restricted payments, creation of certain liens, and certain corporate acts such as mergers, consolidations and sale of substantially all assets. The Securitization Program has a minimum borrowing requirement equal to the lesser of either 80% of our borrowing capacity or 100% of our borrowing base, which is a subset of the trade receivables sold under this agreement. As of January 3, 2015, our minimum borrowing requirement is $80,000.
	In addition to the Securitization Program, we maintain short-term credit facilities with banks throughout the world that are principally demand lines subject to revision by the banks.
	On November 21, 2014, we completed the sale of $300,000 aggregate principal amount of 5.25% senior notes due December 1, 2022 at par with interest paid semiannually on June 1 and December 1 of each year, commencing on June 1, 2015. The aggregate net proceeds of $294,718 were used to repay indebtedness under our U.S. bank credit facility, thereby increasing the unused portion of our revolving credit facility.
	On May 22, 2014, we amended our U.S. revolving credit facility. The amendment increased the capacity on our revolving credit facility from $900,000 to $1,100,000 and extended the maturity of the credit facility to May 22, 2019. The amendment also provides an expansion option, which permits us to request an increase of up to $200,000 to the credit facility upon satisfaction of certain conditions. The credit facility is secured by substantially all of our U.S. assets.
	On December 19, 2013, we repurchased our 7.25% senior subordinated notes due on January 15, 2018 at 103.625%, pursuant to an early redemption right. We redeemed the aggregate principal amount of $200,000 using proceeds drawn from our U.S. revolving credit facility. The associated loss on the redemption includes $6,945 of call premium paid to external bondholders and a $1,057 write off of deferred debt issuance costs.

Derivative Instruments and Hedges, Assets [Abstract]
Derivative Financial Instruments	Derivative Financial Instruments
	We principally use derivative financial instruments to manage interest rate risk associated with long-term debt and foreign exchange risk related to foreign operations and foreign currency transactions. We enter into derivative financial instruments with a number of major financial institutions to minimize counterparty credit risk.
	Derivatives designated as hedging instruments
	Interest rate swaps are used to adjust the proportion of total debt that is subject to variable and fixed interest rates. The interest rate swaps are designated as hedges of the amount of future cash flows related to interest payments on variable-rate debt that, in combination with the interest payments on the debt, convert a portion of the variable-rate debt to fixed-rate debt. At January 3, 2015, we had interest rate swaps with notional amounts totaling $320,000. The interest rate swaps effectively convert this amount of variable-rate debt to fixed-rate debt at 2.0%, including the applicable margin of 138 basis points as of January 3, 2015. The interest will revert back to variable rates based on LIBOR plus the applicable margin upon the maturity of the interest rate swaps. These interest rate swaps mature at various times between January 15, 2015 and June 5, 2017.
	We use foreign currency forward contracts as cash flow hedges to effectively fix the exchange rates on future payments and revenue. To mitigate exposure in movements between various currencies, primarily the Philippine peso, we had outstanding foreign currency forwards with notional amounts of $41,297 at January 3, 2015. These contracts mature at various times through August 26, 2016.
	These interest rate swaps and foreign currency forwards are recorded in the consolidated condensed balance sheets at fair value and the related gains or losses are deferred in shareholders’ equity as a component of Accumulated Other Comprehensive Income (Loss) (AOCI). These deferred gains and losses are reclassified into expense during the periods in which the related payments or receipts affect earnings. However, to the extent the interest rate swaps and foreign currency forwards are not perfectly effective in offsetting the change in the value of the payments and revenue being hedged, the ineffective portion of these contracts is recognized in earnings immediately. Ineffectiveness was not material in the first three months of 2015 or 2014.
	Derivatives not designated as hedging instruments
	We also have foreign currency exposure on balances, primarily intercompany, that are denominated in foreign currencies and are adjusted to current values using period-end exchange rates. The resulting gains or losses are recorded in the consolidated condensed statements of earnings. To minimize foreign currency exposure, we had foreign currency forwards with notional amounts of $145,420 at January 3, 2015. The foreign currency forwards are recorded in the consolidated condensed balance sheets at fair value and resulting gains or losses are recorded in the consolidated condensed statements of earnings. We recorded the following gains or losses on foreign currency forwards which are included in other income or expense and generally offset the gains or losses from the foreign currency adjustments on the intercompany balances that are also included in other income or expense:

Fair Value Disclosures [Abstract]
Fair Value	Fair Value
	Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Depending on the nature of the asset or liability, various techniques and assumptions can be used to estimate fair value. The definition of the fair value hierarchy is as follows:
	Level 1 – Quoted prices in active markets for identical assets and liabilities.
	Level 2 – Observable inputs other than quoted prices in active markets for similar assets and liabilities.
	Level 3 – Inputs for which significant valuation assumptions are unobservable in a market and therefore value is based on the best available data, some of which is internally developed and considers risk premiums that a market participant would require.
	Our derivatives are valued using various pricing models or discounted cash flow analyses that incorporate observable market data, such as interest rate yield curves and currency rates, and are classified as Level 2 within the valuation hierarchy. Our Level 3 fair value liabilities represent contingent consideration recorded for acquisitions to be paid if various financial targets are met. The amounts recorded were calculated for each payment scenario in each period using an estimate of the probability of the future cash outflows. The varying contingent payments were then discounted to the present value at the weighted average cost of capital. Fair value is assessed on a quarterly basis, or whenever events or circumstances change that indicates an adjustment is required. The assessment includes an evaluation of the performance of the acquired business compared to previous expectations, changes to future projections and the probability of achieving the earn out targets.
	The following table presents the fair values and classification of our financial assets and liabilities measured on a recurring basis as of January 3, 2015:
		Classification	Level 1		Level 2		Level 3		Total
	Foreign currency forwards	Other assets	$	—	$	1,283	$	—	$	1,283
	Interest rate swaps	Other assets	—		1		—		1

Restructuring and Related Activities [Abstract]
Restructuring	Restructuring
	In 2013, we initiated restructuring plans to better align our cost structure with projected sales levels. The restructuring actions taken have resulted in workforce reductions, primarily in the U.S., Europe and Asia.
	In 2014, we initiated restructuring plans in response to the business outlook, which includes a change in the mix of sales and delays and cancellations of orders for certain product lines. The restructuring actions taken have resulted in workforce reductions, primarily in the U.S. and Europe.
	Restructuring activity for severance by segment is as follows:
		Aircraft Controls			Space and Defense Controls			Industrial Systems			Total
	Balance at September 27, 2014	5,439			5,764			186			11,389

	Balance at January 3, 2015	$	2,755		$	2,988		$	—		$	5,743
	Payments related to these severance benefits are expected to be paid in full by April 4, 2015 for the 2013 plan and primarily by October 3, 2015 for the 2014 plan, with the exception of amounts classified as long-term liabilities based on payment arrangements. As of January 3, 2015, restructuring consists of $5,634 for the 2014 plan and $109 for the 2013 plan.

	The effective tax rates of 28.7% for the three months ended January 3, 2015 and 31.5% and for the three months ended December 28, 2013 are lower than would be expected by applying the U.S. federal statutory tax rate to earnings before income taxes primarily as a result of a significant portion of our earnings that come from foreign operations with lower tax rates.

	From time to time, we are involved in legal proceedings. We are not a party to any pending legal proceedings which management believes will result in a material adverse effect on our financial condition, results of operations or cash flows.
	We are engaged in administrative proceedings with governmental agencies and legal proceedings with governmental agencies and other third parties in the normal course of our business, including litigation under Superfund laws, regarding environmental matters. We believe that adequate reserves have been established for our share of the estimated cost for all currently pending environmental administrative or legal proceedings and do not expect that these environmental matters will have a material adverse effect on our financial condition, results of operations or cash flows.
	In the ordinary course of business we could be subject to ongoing claims or disputes from our customers, the ultimate settlement of which could have a material adverse impact on our consolidated results of operations. While the receivables and any loss provisions recorded to date reflect management's best estimate of the projected costs to complete a given project, there is still significant effort required to complete the ultimate deliverable. Future variability in internal cost and as well as future profitability is dependent upon a number of factors including deliveries, performance and government budgetary pressures. The inability to achieve a satisfactory contractual solution, further unplanned delays, additional developmental cost growth or variations in any of the estimates used in the existing contract analysis could lead to further loss provisions. Additional losses could have a material adverse impact on our financial condition, results of operations or cash flows in the period in which the loss may be recognized.
	We are contingently liable for $13,859 of standby letters of credit issued by a bank to third parties on our behalf at January 3, 2015.

	In March 2013, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2013-05, "Parent's Accounting for the Cumulative Translation Adjustment upon Derecognition of Certain Subsidiaries or Group of Assets within a Foreign Entity or of an Investment in a Foreign Entity." This ASU is intended to eliminate diversity in practice on the release of cumulative translation adjustments into net income when a parent either sells part or all of its investment in a foreign entity, or when it no longer holds a controlling financial interest. In addition, the amendments resolve the diversity in practice for the treatment of business combinations achieved in stages involving a foreign entity. The provisions of this ASU are effective for fiscal years beginning after December 15, 2013 and interim periods within those fiscal years. We adopted this amendment in the first quarter of 2015. The adoption of this standard did not have a material impact on our financial statements.
