Abstract: A portable rescue device (PRD) includes, a sensor, a display unit, and a wireless receiver configured to receive a distress signal from a portable distress device (PDD). The PRD further includes a processor communicably coupled to each of the display unit, the wireless receiver, and the sensor. The processor is configured to determine one or more path obstacles disposed in a first direction between the wireless receiver and the PDD along which the distress signal has a maximum signal strength based on an obstacle signal generated by the sensor. The processor is further configured to determine at least one obstacle-free path unobstructed by the one or more path obstacles. The processor is further configured to determine at least one set of guiding directions for guiding the user along the at least one obstacle-free path. The processor is further configured to display the at least one set of guiding directions.

Abstract: A chain conveyor paddle attachment bracket for coupling a paddle to a chain link is disclosed. In embodiments, the chain conveyor paddle attachment bracket includes a bent sheet of metal that forms a first portion and a second portion substantially perpendicular to one another. The first portion of the bent sheet of metal includes two notches on opposite sides of the first portion, wherein the two notches are configured to form a welding interface between the first portion of the bent sheet of metal and a sidebar of the chain link. The second portion of the bent sheet of metal includes an opening configured to receive a fastener for connecting the paddle to the second portion of the bent sheet of metal.
