Summary of Significant Accounting Policies [Abstract] |
Basis of Presentation | 1. Basis of Presentation The accompanying unaudited Condensed Consolidated Financial Statements have been prepared in accordance with the instructions to Form 10-Q and Article 10 of Regulation S-X and include all of the information and disclosures required by generally accepted accounting principles in the United States ("GAAP") for interim financial reporting. These unaudited Condensed Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements of the Company and related footnotes for the year ended December 31, 2017, included in the Company’s Annual Report on Form 10-K filed with the Securities and Exchange Commission on March 26, 2018. The results of operations for the interim periods are not necessarily indicative of results of operations for a full year. It is the opinion of management that all necessary adjustments for a fair presentation of the results of operations for the interim periods have been made and are of a recurring nature unless otherwise disclosed herein.
Revenue Recognition | 2. Revenue Recognition We recognize revenue on accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 606, Revenue from Contracts with Customers, which we adopted effective January 1, 2018, using the modified retrospective method. See further discussion of the impact of adoption and current revenue recognition policy in Note 4.
Inventories | 3. Inventories Inventories are stated at the lower of cost or market (net realizable value), determined by the first-in, first-out (FIFO) method, and consist of the following:
|  | March 31, |  |  | December 31, |
|  | 2018 |  |  | 2017 |
Finished goods |  | $ | 615 |  |  | $ | 719 |
Work-in-process |  |  | 155 |  |  |  | 132 |
Total inventories |  | $ | 770 |  |  | $ | 851 |
Impairment of Long-Lived Assets | 4. Impairment of Long-Lived Assets We review the carrying value of all long-lived assets, including property and equipment, for impairment in accordance with ASC 360-10-05-4, Accounting for the Impairment or Disposal of Long-Lived Assets. Under ASC 360-10-05-4, impairment losses are recorded whenever events or changes in circumstances indicate the carrying value of an asset may not be recoverable. If the impairment tests indicate that the carrying value of the asset is greater than the expected undiscounted cash flows to be generated by such asset, an impairment loss would be recognized. The impairment loss is determined as the amount by which the carrying value of such asset exceeds its fair value. We generally measure fair value by considering sale prices for similar assets or by discounting estimated future cash flows from such assets using an appropriate discount rate. Assets to be disposed of are carried at the lower of their carrying value or fair value less costs to sell. Considerable management judgment is necessary to estimate the fair value of assets, and accordingly, actual results could vary significantly from such estimates.
Basic and Diluted Income/(Loss) per Common Share | 5. Basic and Diluted Income/(Loss) per Common Share Basic and diluted income/(loss) per common share for all periods presented is computed using the weighted average number of common shares outstanding. Basic weighted average shares outstanding includes only outstanding common shares. Diluted weighted average shares outstanding includes outstanding common shares and potential dilutive common shares outstanding in accordance with the treasury stock method. Shares reserved for outstanding stock options and warrants totaling approximately 48.5 and 35.9 million at March 31, 2018 and March 31, 2017, respectively, were excluded from the computation of income/(loss) per share. Additionally, the potential common shares issuable upon conversion of convertible preferred stock and convertible promissory notes of 37.7 and 37.7 million were excluded at March 31, 2018 and 2017, respectively, as their effect was antidilutive due to net loss. Net income/(loss) attributable to common shareholders for the three months ended March 31, 2018 and 2017 is after dividends on convertible preferred stock of $111 and $113, respectively.
Income Taxes | 6. Income Taxes Deferred income taxes are recognized in the financial statements for the tax consequences in future years of differences between the tax basis of assets and liabilities and their financial reporting amounts based on enacted tax laws and statutory tax rates. Temporary differences arise from net operating losses, differences in basis of intangibles (other than goodwill), stock-based compensation, reserves for uncollectible accounts receivable and inventory, differences in depreciation methods, and accrued expenses. Valuation allowances are established when necessary to reduce deferred tax assets to the amount expected to be realized. The Company accounts for uncertain tax positions utilizing an established recognition threshold and measurement attributes for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. We had no uncertain tax positions as of March 31, 2018 and December 31, 2017.
Goodwill and Definite-Lived Intangible Assets | 7. Goodwill and Definite-Lived Intangible Assets We follow the provisions of ASC 350, Goodwill and Other Intangible Assets. Pursuant to ASC 350, goodwill acquired in a purchase business combination is not amortized, but instead tested for impairment at least annually. The Company uses a measurement date of September 30. There was no impairment loss recognized on goodwill or definite-lived intangible assets during the three months ended March 31, 2018 and 2017 (see Note 7).
Use of Estimates | 8. Use of Estimates The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Our significant estimates include: the allowance for doubtful accounts, recognition of revenue, deferred tax assets, deferred revenue, depreciable lives and depreciation methods for property and equipment, valuation of warrants and other stock-based compensation and other assumptions and estimates used to evaluate the recoverability of long-lived assets, goodwill and other intangible assets and the related amortization methods and periods. Actual results could differ from those estimates.

- Definition Disclosure of accounting policy for revenue recognition.

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. + References Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Accounting Standards Codification -Topic 235 -SubTopic 10 -Section 50 -Paragraph 4 -URI http://asc.fasb.org/extlink&oid=84158767&loc=d3e18823-107790 Reference 2: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Accounting Standards Codification -Topic 605 -SubTopic 10 -Section S99 -Paragraph 1 -Subparagraph (SAB Topic 13.B.Q1) -URI http://asc.fasb.org/extlink&oid=65893310&loc=d3e214044-122780 Reference 3: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Accounting Standards Codification -Topic 235 -SubTopic 10 -Section 50 -Paragraph 3 -URI http://asc.fasb.org/extlink&oid=84158767&loc=d3e18780-107790 Reference 4: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Accounting Standards Codification -Topic 235 -SubTopic 10 -Section 50 -Paragraph 1 -URI http://asc.fasb.org/extlink&oid=84158767&loc=d3e18726-107790 + Details
