Subsequent Events [Text Block]	*Note 19.* Subsequent Events** On Monday, July 8, 2024, Hurricane Beryl came ashore as a category-1 hurricane in the area east of Matagorda, Texas, approximately 70 miles southwest of the Company's headquarters facility in Sugar Land, TX. The Company's headquarters facility and its manufacturing and R&D facilities in Sugar Land suffered power outages from July 8, 2024 to July 11, 2024. The Company's backup power generators worked as designed, but were sufficient to allow only limited business activity. The Company's facilities are believed to have suffered no material damage as a result of the hurricane, and the Company is working to recover any production which was delayed by the power loss. Currently the Company expects no material financial impact due to the storm.
