Abstract: Embodiments of the present invention provide wireless control devices that operate in-field wirelessly without removable batteries, have power self-harvesting components, and can be wirelessly programmed over long ranges without interfering with the normal operation of the control devices. Only control devices that have sufficient power available to perform a reprogram cycle (and can function normally until a next power harvest cycle) are selected. Control devices can be selected for wireless reprogramming based on the upcoming functions to be performed by the control device, the amount of energy stored in the control device, the rate of power generation of a solar panel of the control device, and current and upcoming weather conditions, etc. The wireless programming can include updating a firmware of the control device, a bootloader of the control device, and an application program image.

Abstract: A method of forming a nonwoven article comprising receiving fibrous material comprising thermoplastic fibers; processing the fibrous material to produce short fibers, wherein the processing step comprises granulation using at least one granulator with a screen; distributing the short fibers approximately evenly across an area to form a short fiber web, wherein the distributing step comprises a use of a recyclate spreader; heating the short fiber web to fuse the short fibers to form a nonwoven material; and forming a sheet of the nonwoven material.

Abstract: An in-tire sound absorber for a pneumatic wheel assembly including a wheel rim and a tire fitted to the wheel rim. The sound absorber is adapted to be located within a cavity defined by the wheel rim and the tire. The sound absorber comprises a first fibrous layer and a second fibrous layer. The second fibrous layer has a higher air flow resistance than the first fibrous layer. The first fibrous layer, the second fibrous layer, or both, is made from a non-woven fibrous web.
