Feel free to call us at the telephone numbers listed at the end of this letter. Form 10-K for the year ended October 28, 2005 Item 9A. Controls and Procedures, page 23 1. We note your disclosure that "disclosure controls and procedures were effective to ensure that information [you] are required to disclose in the reports that [you] file under the Exchange Act is recorded, processed, summarized and reported within time periods specified in Securities and Exchange Commission rules and forms." Please revise future filings to clarify, if true, that your officers concluded that your disclosure controls and procedures are also effective to ensure that information required to be disclosed in the reports that you file or submit under the Exchange Act is accumulated and communicated to your management, including your chief executive officer and chief financial officer, to allow timely decisions regarding required disclosure. See Exchange Act Rule 13a-15(e). Management`s Discussion and Analysis of Financial Condition and Results of Continuing Operations, page 2 Contractual Obligations, page 16 2. Revise future filings to disclose your off-balance sheet arrangements in a separately captioned subsection of MD&A as required by Item 303(a)(4) of Regulation S-K. Also, make the detailed disclosures required by paragraphs (a)(4)(i) of this Item, to the extent necessary to understand your off-balance sheet arrangements and their effect on financial condition, changes in financial condition and results of operations. Consolidated Statement of Operations, page 32 3. We note that you recorded a $3.4 million gain on sale of product line in fiscal 2004. If you recognize a gain or loss that is not a component of an entity, you should include that amount in income from continuing operations before income taxes. See paragraph 45 of SFAS 144. Revise future filings as necessary. Consolidated Statement of Shareholders` Equity and Comprehensive Income, page 38 4. Please expand your disclosures, here or in a financial statement footnote, in future filings, to show changes in the number of common shares during each period for which an income statement has been presented, as contemplated by Rule 5-02.30 of Regulation S-X. Notes to Consolidated Financial Statements, page 39 Note 1. Accounting Policies, page 39 Product Warranties, page 44 5.

Acquisitions and Divestitures, page 66 6. In periods where you consummate a material business acquisition, please revise future filings to make the pro forma disclosures required by paragraphs 54-55 of SFAS 141. 7.
