Accounting Policies [Abstract]
Revenue Recognition, Policy	In October 2009, the FASB issued a new accounting standard for multiple deliverable revenue arrangements. The new standard changes the requirements for establishing separate units of accounting in a multiple element arrangement and requires the allocation of arrangement consideration to each deliverable to be based on the relative selling price. The FASB also issued a new accounting standard for certain revenue arrangements that include software elements. This new standard excludes software that is contained on a tangible product from the scope of software revenue guidance if the software is essential to the tangible product’s functionality. We prospectively adopted both these standards in the first quarter of fiscal 2011 and it did not have a material impact on our consolidated financial position, results of operations and cash flows.

Disclosure of accounting policy for revenue recognition. If the entity has different policies for different types of revenue transactions, the policy for each material type of transaction is generally disclosed. If a sales transaction has multiple element arrangements (for example, delivery of multiple products, services or the rights to use assets) the disclosure may indicate the accounting policy for each unit of accounting as well as how units of accounting are determined and valued. The disclosure may encompass important judgment as to appropriateness of principles related to recognition of revenue. The disclosure also may indicate the entity's treatment of any unearned or deferred revenue that arises from the transaction.
