Accounting Policies [Abstract]  
Unaudited Interim Financial Statements
Unaudited Interim Financial Statements
   
  The accompanying unaudited interim condensed consolidated financial statements have been prepared in accordance with U.S. GAAP for interim financial information and with the instructions to Form 10-Q and Article 10 of U.S. Securities and Exchange Commission (“SEC”) regulations. Accordingly, they do not include all the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments considered necessary for a fair presentation have been included (consisting only of normal recurring adjustments except as otherwise discussed).
   
  Operating results for the three and six months periods ended June 30, 2019, are not necessarily indicative of the results that may be expected for the year ended December 31, 2019.
Significant Accounting Policies
  Significant Accounting Policies
   
  The significant accounting policies followed in the preparation of these unaudited interim condensed consolidated financial statements are identical to those applied in the preparation of the latest annual audited financial statements with the exception of the following:
Short-term Investments
Short-term Investments
   
  The Company began investing excess cash in short-term investments during the first quarter of 2019.
   
  Marketable debt securities are considered to be available for sale and are carried at fair value. Unrealized gains and losses net of tax, if any, are reported as a separate component of shareholders’ equity. The cost of marketable debt securities classified as available for sale is adjusted for amortization of premiums and accretion of discounts to maturity. Such amortization and accretion are included in interest income. Realized gains and losses and declines in value judged to be other than temporary, if any, are also included in other income, net. Interest on securities classified as available for sale is included in interest income. The cost of securities sold is based on the specific identification method.
   
  Management evaluates whether available-for-sale securities are other-than-temporarily impaired (OTTI) on a quarterly basis. Debt securities with unrealized losses are considered OTTI if the Company intends to sell the security or if it is more likely than not that the Company will be required to sell such security prior to any anticipated recovery. If management determines that a security is OTTI under these circumstances, the impairment recognized in earnings is measured as the entire difference between the amortized cost and the then-current fair value. During the three and six-months ended June 30, 2019, no investment OTTI losses were realized.
Fair Value of Financial Instruments
Fair value of financial instruments:
   
  The carrying values of cash and cash equivalents, other receivable and other accounts payable and accrued liabilities approximate their fair value due to the short-term maturity of these instruments.
   
  The Company measures the fair value of certain of its financial instruments (marketable debt security) on a recurring basis.
   
  A fair value hierarchy is used to rank the quality and reliability of the information used to determine fair values. Financial assets and liabilities carried at fair value will be classified and disclosed in one of the following three categories:
   
  Level 1 - Quoted prices (unadjusted) in active markets for identical assets and liabilities.
   
  Level 2 - Inputs other than Level 1 that are observable, either directly or indirectly, such as unadjusted quoted prices for similar assets and liabilities, unadjusted quoted prices in the markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.
   
  Level 3 - Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.
Leases
Leases
   
  In February 2016, the Financial Accounting Standards Board (“FASB”) issued ASU 2016-02, Leases (Topic 842). This ASU requires entities that lease assets to recognize on the balance sheet the assets and liabilities for the rights and obligations created by leases with lease terms of more than 12 months. The Company adopted this ASU effective January 1, 2019 using the modified retrospective application, applying the new standard to leases in place as of the adoption date. Prior periods have not been adjusted.
   
  Arrangements that are determined to be leases at inception are recognized as long-term right-of-use assets (“ROU”) and lease liabilities in the condensed consolidated balance sheet at lease commencement. Operating lease ROU assets and operating lease liabilities are recognized based on the present value of the future fixed lease payments over the lease term at commencement date. As most of the Company’s leases do not provide an implicit rate, the Company applies its incremental borrowing rate based on the economic environment at commencement date in determining the present value of future payments. Lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Lease expense for operating leases or payments are recognized on a straight-line basis over the lease term.
Warrants
Warrants
   
  Prior to January 1, 2019, warrants with non-standard anti-dilution provisions (referred to as down round protection) were classified as liabilities and re-measured each reporting period. On January 1, 2019, the Company adopted the provisions of Accounting Standards Update (“ASU”) 2017-11, which includes Part I “Accounting for Certain Financial Instruments with Down Round Features” and Part II “Replacement of the Indefinite Deferral for Mandatorily Redeemable Financial Instruments of Certain Nonpublic Entities and Certain Mandatorily Redeemable Non-Controlling Interests with a Scope Exception”, which indicates that a down round feature no longer precludes equity classification when assessing whether an investment is indexed to an entity’s own stock. The Company used a full retrospective approach to adoption and restated its financial statements as of the earliest period presented. As a result of the adoption of ASU 2017-11, the Company’s warrants were reclassified from liabilities to shareholders’ equity.

 

  The cumulative effect of adoption of ASU 2017-11 resulted as follows:

 

   For the
Six Months ended
June 30, 2018
  

For the

year ended
December 31, 2018

 
         
Derivative warrant liability  $         (14)  $(8)
Additional paid-in capital  $-   $28 
Accumulated deficit  $14   $20 

 

  Refer to Note 6 for further information regarding the outstanding warrants as of June 30, 2019.
Recent Accounting Standards
Recent Accounting Standards:
   
  In June 2016, the FASB issued ASU 2016-13 “Financial Instruments – Credit Losses” to improve information on credit losses for financial assets and net investment in leases that are not accounted for at fair value through net income. This ASU replaces the current incurred loss impairment methodology with a methodology that reflects expected credit losses. This ASU is effective for the Company in the first quarter of 2020, with early adoption permitted. The Company does not expect that this ASU will have a material effect on the Company’s consolidated financial statements.
   
  In August 2018, the FASB issued ASU 2018-13, “Changes to Disclosure Requirements for Fair Value Measurements”, which will improve the effectiveness of disclosure requirements for recurring and nonrecurring fair value measurements. This ASU removes, modifies, and adds certain disclosure requirements, and is effective for the Company beginning on January 1, 2020. The Company does not expect that this ASU will have a material effect on the Company’s consolidated financial statements.
