Organization, Consolidation and Presentation of Financial Statements Disclosure and Significant Accounting Policies [Text Block]	2. Principles of Consolidation Our consolidated financial statements include our accounts and those of our wholly owned subsidiaries. Intercompany balances and transactions have been eliminated in consolidation. Cash and Cash Equivalents Cash and all highly liquid investments purchased with an original maturity of less than three Risk Concentration Financial instruments, which potentially subject us to concentrations of credit risk, are primarily cash and cash equivalents, investments and accounts receivable. Cash and cash equivalent deposits are at risk to the extent that they exceed Federal Deposit Insurance Corporation insured amounts. To minimize risk, we place our investments in U.S. government obligations, corporate securities and money market funds. Substantially all of our cash, cash equivalents and investments are maintained with two not not We sell our products to customers primarily in the United States. In the future, we may no Accounts Receivable and Allowance for Doubtful Accounts Trade accounts receivable are stated at the amount we expect to collect. We maintain allowances for doubtful accounts for estimated losses resulting from the inability of our customers to make required payments. Management considers the following factors when determining the collectability of specific customer accounts: customer credit-worthiness, past transaction history with the customer, current economic industry trends, and changes in customer payment terms. If the financial condition of our customers were to deteriorate, adversely affecting their ability to make payments, additional allowances would be required. Based on management’s assessment, we provide for estimated uncollectible amounts through a charge to earnings and an increase to a valuation allowance. Balances that remain outstanding after we have used reasonable collection efforts are written off through a charge to the valuation allowance. There was no December 31, 2018 2017.

Consolidation, Policy [Policy Text Block]	Principles of Consolidation Our consolidated financial statements include our accounts and those of our wholly owned subsidiaries. Intercompany balances and transactions have been eliminated in consolidation.
Cash and Cash Equivalents, Policy [Policy Text Block]	Cash and Cash Equivalents Cash and all highly liquid investments purchased with an original maturity of less than three
Concentration Risk, Credit Risk, Policy [Policy Text Block]	Risk Concentration Financial instruments, which potentially subject us to concentrations of credit risk, are primarily cash and cash equivalents, investments and accounts receivable. Cash and cash equivalent deposits are at risk to the extent that they exceed Federal Deposit Insurance Corporation insured amounts. To minimize risk, we place our investments in U.S. government obligations, corporate securities and money market funds. Substantially all of our cash, cash equivalents and investments are maintained with two not not We sell our products to customers primarily in the United States. In the future, we may no
Trade and Other Accounts Receivable, Policy [Policy Text Block]	Accounts Receivable and Allowance for Doubtful Accounts Trade accounts receivable are stated at the amount we expect to collect. We maintain allowances for doubtful accounts for estimated losses resulting from the inability of our customers to make required payments. Management considers the following factors when determining the collectability of specific customer accounts: customer credit-worthiness, past transaction history with the customer, current economic industry trends, and changes in customer payment terms. If the financial condition of our customers were to deteriorate, adversely affecting their ability to make payments, additional allowances would be required. Based on management’s assessment, we provide for estimated uncollectible amounts through a charge to earnings and an increase to a valuation allowance. Balances that remain outstanding after we have used reasonable collection efforts are written off through a charge to the valuation allowance. There was no December 31, 2018 2017.

The expected term considers the contractual term of the option as well as historical exercise and forfeiture behavior. The risk-free interest rate is based on the rates in effect on the grant date for U.S. Treasury instruments with maturities matching the relevant expected term of the award.
