Organization, Consolidation and Presentation of Financial Statements [Abstract]  
Condensed consolidated financial statements
The accompanying Condensed Consolidated Financial Statements include the accounts of the Company and its wholly owned subsidiaries. The Condensed Consolidated Financial Statements have been prepared using generally accepted accounting principles (GAAP) in the United States for interim financial reporting, and consistent with the instructions of Form 10-Q and Article 10 of Regulation S-X, and accordingly they do not include all of the information and footnotes required in the annual consolidated financial statements and accompanying footnotes. The Condensed Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements and accompanying notes included in the Company’s Annual Report on Form 10-K for the year ended March 31, 2013. All intercompany accounts and transactions have been eliminated in consolidation.
Use of Estimates
The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements, and that affect revenue and expenses during the period reported. Estimates are used when accounting for the allowance for uncollectible accounts receivable, excess and obsolete inventory, net realizable value of inventory, product warranty accrued, relative selling prices, stock-based compensation, goodwill and intangible asset fair value, depreciation, income taxes, contingent consideration and contingencies, among other things. These estimates are based on management’s best estimates and judgment. Management evaluates its estimates and assumptions on an ongoing basis using historical experience and other factors. The Company adjusts such estimates and assumptions when facts and circumstances dictate. Actual results could differ from those estimates.
New Accounting Pronouncements, Policy
Recently Adopted Accounting Pronouncements
In July 2013, the FASB issued ASU No. 2013-11, Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists (“ASU 2013-11”). Prior to ASU 2013-11, Topic 740, Income Taxes, did not include explicit guidance on the financial statement presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. The objective of ASU 2013-11 is to eliminate that diversity in practice in the presentation of unrecognized tax benefits in those cases. ASU 2013-11 generally requires that an unrecognized tax benefit should be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward. Effective for the first quarter of fiscal year 2014, the Company elected the early adoption of this provision with retrospective application. As a result, the Condensed Consolidated Balance Sheet as of March 31, 2013, reflects an adjustment to the previously issued audited financial statements to reclassify $2.7 million of unrecognized tax benefits from tax contingency reserve long-term to deferred income taxes non-current. This balance sheet reclassification had no impact on the historical condensed consolidated statements of operations or accumulated defecit.
Revenue Recognition, Policy
Revenue Recognition and Deferred Revenue
The Company's revenue is derived from the sale of products, software, and services. The Company records revenue from product sales transactions when title and risk of loss are passed to the customer, there is persuasive evidence of an arrangement for sale, delivery has occurred and/or services have been rendered, the sales price is fixed or determinable, and collectability is reasonably assured.
Revenue recognition on equipment where software is incidental to the product as a whole, or where software is essential to the equipment’s functionality and falls under software accounting scope exceptions, generally occurs when products are shipped, risk of loss has transferred to the customer, objective evidence exists that customer acceptance provisions have been met, no significant obligations remain, collection is reasonably assured and warranty can be estimated.
Revenue recognition where software that is more than incidental to the product as a whole or where software is sold on a standalone basis is recognized when the software is delivered and ownership and risk of loss are transferred.
The Company also recognizes revenue from deployment services, maintenance agreements, training and professional services. Deployment services revenue results from installation of products at customer sites. Deployment services, which generally occur over a short time period, are not services required for the functionality of products, because customers do not have to purchase installation services from the Company, and may install products themselves, or hire third parties to perform the installation services. Revenue for deployment services, training and professional services are recognized upon completion. Revenue from maintenance agreements is recognized ratably over the service period.
When a multiple element arrangement exists, the fee from the arrangement is allocated to the various deliverables so that the proper amount can be recognized as revenue as each element is delivered. Based on the composition of the arrangement, the Company analyzes the provisions of the accounting guidance to determine the appropriate model that is applied towards accounting for the multiple element arrangement. If the arrangement includes a combination of elements that fall within different applicable guidance, the Company follows the provisions of the hierarchal literature to separate those elements from each other and apply the relevant guidance to each.
If deliverables do not fall within the software revenue recognition guidance, the fair value of each element is established using the relative selling price method, which requires the Company to use vendor-specific objective evidence ("VSOE"), reliable third-party objective evidence or management's best estimate of selling price, in that order.
If deliverables fall within the software revenue recognition guidance, the fee is allocated to the various elements based on VSOE of fair value. If sufficient VSOE of fair value does not exist for the allocation of revenue to all the various elements in a multiple element arrangement, all revenue from the arrangement is deferred until the earlier of the point at which such sufficient VSOE of fair value is established or all elements within the arrangement are delivered. If VSOE of fair value exists for all undelivered elements, but does not exist for one or more delivered elements, the arrangement consideration is allocated to the various elements of the arrangement using the residual method of accounting. Under the residual method, the amount of the arrangement consideration allocated to the delivered elements is equal to the total arrangement consideration less the aggregate fair value of the undelivered elements. Using this method, any potential discount on the arrangement is allocated entirely to the delivered elements, which ensures that the amount of revenue recognized at any point in time is not overstated. Under the residual method, if VSOE of fair value exists for the undelivered element, generally maintenance, the fair value of the undelivered element is deferred and recognized ratably over the term of the maintenance contract, and the remaining portion of the arrangement is recognized as revenue upon delivery, which generally occurs upon delivery of the product.
The Company’s product return policy allows customers to return unused equipment for partial credit if the equipment is non-custom product, returned within specified time limits, and currently being manufactured and sold. Credit is not offered on returned products that are no longer manufactured and sold. The Company’s reserve for returns is not significant.
The Company records revenue net of taxes in accordance with ASC topic 605, Revenue Recognition (“ASC 605”).
Inventories are stated at the lower of first-in, first-out cost or market value.
Fair Value Measurement
Fair value is defined by ASC 820 as the price that would be received upon selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. ASC 820 establishes a three-level fair value hierarchy that prioritizes the inputs used to measure fair value. The hierarchy requires entities to maximize the use of observable inputs and minimize the use of unobservable inputs. The three levels of inputs used to measure fair value are as follows:

Level 1 – Quoted prices in active markets for identical assets and liabilities.
Level 2 – Quoted prices in active markets for similar assets and liabilities, or other inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument.
Level 3 – Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets and liabilities. This includes certain pricing models, discounted cash flow methodologies and similar techniques that use significant unobservable inputs.
