Various embodiments of the present disclosure are directed to systems and methods of utilizing a convolutional neural network to detect freezing of gait in patients and provide vibration to return to normal motor function. A system can perform a method of training a convolutional neural network by receiving a video recording; receiving a plurality of timestamp selections indicating when the person demonstrates a freezing of gait event during the video; receiving movement data from the sensing device; extracting domain data from the movement data; providing the plurality of domain data to the convolutional neural network; and deploying the convolutional neural network on a client device. Additionally, a system can be arranged to perform a method of receiving movement data from the sensing device; determining a categorization of the movement by processing the movement data through a convolutional neural network; and directing a vibration delivery device to deliver vibration.

Herein we describe embodiments of shotgun shells, methods for loading such shotgun shells, and methods for using them. In some embodiments, the shotgun shells utilize a multi-component wad system with a biodegradable powder wad that stays intact through the firing process, and a separate and chemically distinct biodegradable shot wad that breaks apart within one meter after being shot out of the barrel of a shotgun. A clean release of the shot can be obtained, providing both high performance and biodegradability. The biodegradable shot wad can be a biodegradable polyester.

Herein we describe embodiments of a biodegradable wad having a gas sealing function, as well as methods for their use. In some embodiments, the biodegradable wad comprises at least 50% by weight of a poly(butylene succinate co-adipate) polymer. In some embodiments, the biodegradable wad comprises at least two biodegradable polymers, wherein a first biodegradable polymer comprises a polybutylene succinate adipate polymer and a second biodegradable polymer comprises a polyhydroxyalkanoate polymer. Plastic debris has a negative economic and ecological impact, and thus it is advantageous to use implements that will degrade into environmentally benign compounds. Incorporating a biodegradable wad into shotgun shells provides an effective, economical solution, provided cost is acceptable and performance is not compromised. Suitable shotgun shells utilizing biodegradable shotgun wads and methods are described herein.

Herein we describe shotgun shells each having a degradable wad comprising a polyhydroxyalkanoate polymer, as well as methods for ensuring that such wad degrades quickly after landing in an aquatic environment. Plastic, aquatic debris has a negative economic and ecological impact, and thus it is advantageous to use implements that will degrade into environmentally benign compounds. Incorporating a degradable wad into shotgun shells provides an effective, economical solution. Suitable degradable shotgun wads and methods are described herein.
