Latest Patents

Holmgren's latest patents include a "Detector and system for indicating pressure change and methods of use." This invention features an electronic detector configuration that accurately determines pressure differences in scenarios where conventional detectors may fail due to thermal inequalities. A preferred embodiment of this invention measures snow water equivalent (SWE) while eliminating the need for environmentally hazardous fluid-filled pillows. By matching the thermal conductivity of surrounding soil to the detector configuration, it minimizes measurement errors caused by thermal conductivity differences at the snow/soil interface. The system is designed to be environmentally friendly, compact, and cost-effective for various monitoring functions, including snow avalanche and landslide early warning.

Another notable invention is the "Self-recording snow depth probe." This device includes a portable data logger that measures snow depths in snow-covered areas. Key components of the snow probe include a linear displacement magnetostrictive transducer, a floating plate assembly, a pointed tip for easy penetration of snow, and a thumb switch for measurement activation. The device can also feature a polar fleece sleeve for thermal insulation and a digital counter to track measurements.
