    Abstract: An energy harvesting system can be used to exploit freely available flow energy with a piezoelectric device(s). The system may include a piezoelectric device and a flow disruptor, such as a blunt body that creates flow turbulence and flow characteristic randomization that can increase movement response from the piezoelectric device and enhance electrical power generation. Multiple piezoelectric devices may be linked to each other to enhance movement of a less-influenced piezoelectric device from translated movement of a more-influenced piezoelectric device and create more electrical power than a single piezoelectric device subjected to the same flowing fluid.

    Abstract: Multiple spatially diverse and compact weight sensors are statistically combined to reduce or eliminate errors caused by snow bridging. Data transmission using satellite communication minimizes the power consumption of the sensor station further allowing the entire system to be relatively compact and easily transported. The weight sensors may be combined with other standard sensors for measurement of air temperature and snow height, the latter measurement, for example, using ultrasound ranging or the like.

    Abstract: A prefabricated sprue assembly provides attachment to independently-produced investment casting molds to substantially reduce the need for pattern material. Installable connections between the prefabricated sprue assembly and the investment mold allow substantial reduction of scrap loss caused by errors in production of individual investment molds by culling defective molds before installation to the sprue assembly.
