Abstract: A track rail fastening system includes a rail cushion positionable laterally between a first fastener assembly and a second fastener assembly. The rail cushion includes a first full-length pad and a second full-length pad, and a pin field formed by a plurality of deformable pins. The first full-length pad and the second full-length pad define a first rail cushioning plane. The deformable pins in the pin field define a second rail cushioning plane. The cushion is deformable between a rest configuration where the cushioning planes are spaced, and a loaded configuration where the cushioning planes are co-planar. Primary, lower load deformable pins are configured to deflect such that under sufficient load both the primary, lower load deformable pins, and secondary, higher load pins engage an underlying substrate.

Abstract: Waste chute devices and methods for using the same are provided. In some embodiments, a method for operating waste chutes comprises: receiving, using a hardware processor of a waste chute device, an identity associated with a user of the waste chute device; in response to receiving the identity associated with the user, allowing, using the hardware processor, a door of the waste chute device to be opened; determining, using the hardware processor, a number of items and at least one type associated with the items that have been placed in an opening of the waste chute device; determining, using the hardware processor, that the door of the waste chute device has been closed; updating, using the hardware processor, information associated with the user based on the number of items and the at least one type of items that have been placed in the opening of the waste chute device; and providing, using the hardware processor, the user with the updated information.
