Abstract: This paper presents an adaptive bias voltage readout circuit designed for SinglePhoton Avalanche Diode (SPAD) arrays. Due to the combined effects of material defects, process variations, and ...

The group of 15 backcountry skiers would have had only seconds to process the mass of snow heading toward them — traveling at as much as 100 mph — after one skier spotted it and shouted “Avalanche!” ...

Abstract: This article presents technologies for single-photon avalanche diode direct time-of-flight depth sensor and light detection and ranging (LiDAR) systems. The sensor includes a pixel readout ...

The warnings were clear and eerie. A winter storm warning forecast up to 8 feet of snow in California’s Lake Tahoe Region, and avalanche conditions were considered "very dangerous." Blackbird Mountain ...

When the avalanche struck a party of skiers traveling out of Tahoe-area backcountry last week, three people in the party who weren’t buried dug out three companions who survived, according to new ...
