Inventories are stated at the lower of cost or net realizable value using the average cost method. Inventories consisted of:

Equipment is carried at cost and depreciated using the straight-line method over the estimated useful lives of the assets, which is three years. Equipment is stated on the balance sheet net of accumulated depreciation of $29,728 and $31,374 as of December 31, 2011 and June 30, 2012, respectively. Depreciation expense for the six-month periods ended June 30, 2011 and 2012 was $5,197 and $1,646, respectively.

“Other Assets – Deposit” consists of payments made to secure the Ioteq IP patents rights to continue our efforts in commercializing the ISAN system.

We review intangible assets using our best estimates based on reasonable assumptions and projections. An impairment loss to write such assets down to their estimated fair values is necessary if the carrying values of the assets exceed their related undiscounted expected future cash flows. We also determine impairment whenever events or changes in circumstances indicate that their carrying values may not be recoverable.

All share-based payments to employees, including grants of employee stock options, are recognized in the financial statements based on their fair values.

For stock issued to consultants and other non-employees for services, we record the expense based on the fair market value of the securities as of the date of the stock issuance. The issuance of stock warrants or options to non-employees are valued at the time of issuance utilizing the Black Scholes calculation and the amount is charged to expense.

We have established a policy relative to the methodology to determine the value assigned to each intangible we acquire, and/or services or products received for non-cash consideration of our common stock. The value is based on the market price of our common stock issued as consideration, at the date of the agreement of each transaction or when the service is rendered or product is received.

The methods, estimates and judgments we use in applying these most critical accounting policies have a significant impact on the results of our financial statements.

Revenues are recognized as risk and title to products transfers to the customer (which generally occurs at the time shipment is made), the sales price is fixed or determinable, and collectability is reasonably assured. We also may generate revenues from royalties and license fees from our intellectual property. Licensees typically pay a license fee in one or more installments and ongoing royalties based on their sales of products incorporating or using our licensed intellectual property. License fees are recognized over the estimated period of future benefit to the average licensee.

We report basic and diluted earnings (loss) per share (“EPS”) for common and common share equivalents. Basic EPS is computed by dividing reported earnings by the weighted average shares outstanding. Diluted EPS is computed by adding to the weighted average shares the dilutive effect if stock options and warrants were exercised into common stock. For the six-month periods ended June 30, 2011 and 2012, the denominator in the diluted EPS computation is the same as the denominator for basic EPS due to the anti-dilutive effect of the warrants and stock options on the Company’s net loss.

There was no recent accounting guidance issued where the adoption would have a material effect on our condensed consolidated financial statements.
