Bathymetric lidars—devices that employ powerful lasers to scan beneath the water's surface—are used today primarily to map coastal waters. At nearly 600 lb, the systems are large and heavy, and require piloted aircraft to carry them.
A new electrode design for lithium-ion batteries has been shown by Purdue researchers to potentially reduce the charging time from hours to minutes by replacing the conventional graphite electrode with a network of tin-oxide nanoparticles.
New approach to HVAC case design incorporates an optimized center section and side sections that can be shaped and sized for specific performance and packaging. Blower fan remains in separate case and a dual-fan design is available for more precise airflow management between outside air and recirculating air.
