Substantial Doubt about Going Concern [Text Block]	Note 2 - Liquidity As of March 31, 2025, we had $4,316,000 in cash and cash equivalents and working capital of $3,345,000. For the three months ended March 31, 2025, we incurred a net loss of $672,000, financing activities provided $31,000 in net cash, and we used net cash of $680,000 in operating activities. We believe our existing cash and cash equivalents will be sufficient to fund our operations and meet our working capital requirements into the fourth quarter of 2026.

The entire disclosure when substantial doubt is raised about the ability to continue as a going concern. Includes, but is not limited to, principal conditions or events that raised substantial doubt about the ability to continue as a going concern, management's evaluation of the significance of those conditions or events in relation to the ability to meet its obligations, and management's plans that alleviated or are intended to mitigate the conditions or events that raise substantial doubt about the ability to continue as a going concern.
