Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The Condensed Consolidated Financial Statements include our results of our consolidated subsidiaries. Intercompany accounts and transactions have been eliminated. Noncontrolling interests represent the noncontrolling stockholders’ proportionate share of the net assets and results of operations of our consolidated subsidiaries. We use a 52- to 53-week year ending on the Friday nearest to December 31. Both 2022 and 2021 are 52-week years. The first quarter of 2022 and 2021 ended on April 1, 2022 and April 2, 2021. Unless otherwise stated, all dates refer to these periods.
Use of Estimates	Use of Estimates We prepared our interim Condensed Consolidated Financial Statements that accompany these notes in conformity with U.S. GAAP, consistent in all material respects with those applied in our Form 10-K filed with the U.S. Securities and Exchange Commission on February 23, 2022 (the “2021 Form 10-K”). The interim financial information is unaudited, and reflects all normal adjustments that are, in our opinion, necessary to provide a fair statement of results for the interim periods presented. This report should be read in conjunction with our 2021 Form 10-K that includes additional information about our significant accounting policies and the methods and assumptions used in our estimates. The preparation of financial statements in accordance with U.S. generally accepted accounting principles (“GAAP”) requires us to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Estimates and assumptions are used for revenue recognition, including determining the nature and timing of satisfaction of performance obligations and determining standalone selling price (“SSP”) of performance obligations, provision for credit losses, sales returns reserve, inventory valuation, warranty costs, investments, acquired intangibles, goodwill and intangible asset impairment analysis, other long-lived asset impairment analysis, stock-based compensation, and income taxes. We base our estimates on historical experience and various other assumptions we believe to be reasonable. Actual results that we experience may differ materially from our estimates.
Recently Adopted Accounting Pronouncements	Recently issued Accounting Pronouncements not yet Adopted There are no recently issued accounting pronouncements applicable to us not yet adopted. Recently Adopted Accounting Pronouncements There are no recently adopted accounting pronouncements.
Product Warranties	We accrue for warranty costs as part of our cost of sales based on associated material product costs, technical support, labor costs, and costs incurred by third parties performing work on our behalf. Our expected future costs are primarily estimated based upon historical trends in the volume of product returns within the warranty period and the costs to repair or replace the equipment. When products sold include warranty provisions, they are covered by a warranty for periods ranging generally from one year to two years.
