Subsequent Events [Text Block]	13. Subsequent Events The outbreak of COVID- 19 (coronavirus) caused by a novel strain of the coronavirus has recently been recognized as a pandemic by the World Health Organization, and the outbreak has become increasingly widespread in the United States. The COVID- 19 outbreak has had a notable impact on general economic conditions, including, but not limited to, the temporary closures of many businesses, “shelter in place” and other governmental regulations, and “work from home” directives, and there are many unknowns. Notable potential effects on the Company include U.S. government procurements may be delayed or cancelled, work on existing contracts that require personal interactions may be suspended, payment processing for customer invoices may be delayed, employees and customers may become infected, and sales meetings may not be able to take place. The Company continues to monitor the impact of the COVID- 19 outbreak closely. The extent to which the COVID- 19 outbreak will impact the Company’s business, results of operations, financial condition, and cash flows is uncertain.
