Abstract: Cart bumpers and carts including cart bumpers are described. In one example, a cart bumper can include an outer contact wall, an inner rim that defines an inner surface, where the inner surface comprises recesses, a number of spokes extending between the inner rim and the outer contact wall, a mounting ring that defines an outer surface, where the outer surface is in contact with the inner surface, and a number of protruding ribs configured to engage respective recesses on the inner surface.

Abstract: Authentication method and systems using RFID-enabled payment cards are disclosed herein where a server receives a request corresponding to authorization of a payment associated with a payment card from an electronic terminal. The server identifies an electronic device of a user associated with the payment card. The server then transmits an instruction to the electronic device to cause an RFID reader of the electronic device to determine whether an RFID tag corresponding to the payment card is located within a predetermined proximity to the electronic device. When the payment card is located within the predetermined proximity, the server executes a first authentication protocol. Moreover, when the payment card is not located within the predetermined proximity, the server executes a second authentication protocol, wherein the second authentication protocol is more restrictive than the first authentication protocol.

Abstract: A system according to one embodiment includes a first computing device comprising ultra-wideband communication circuitry, and a second computing device comprising ultra-wideband communication circuitry configured to communicate with the ultra-wideband communication circuitry of the first computing device to determine the angle and distance of the first computing device relative to the second computing device.

Abstract: A waste receptacle may include a housing, a rectangular rim defining a rim opening, and a plurality of retention tabs extending from the rim. The plurality of retention tabs includes a notched retention tab defining a retention notch between first and second tab portions. The first and second tab portions are configured to respectively retain first and second liners received within the rim opening being diagonally opposed. The plurality of retention liners is configured to receive a larger third liner. The waste receptacle may include a cinch extending from the rim. The cinch may include a cinch base defining a pair of openings, and a cinch tab between the openings. The cinch tab may extend from the cinch base. The cinch is configured to receive a portion of a liner received in the rim opening between the openings and across the cinch tab.

Abstract: Cart bumpers and carts including cart bumpers are described. In aspects, a cart bumper includes an outer contact wall, an inner rim, and a plurality of spokes extending from the inner rim to the outer contact wall, each spoke of the plurality of spokes defining a respective path. The outer contact wall and the plurality of spokes are configured to collapse in response to a mechanical force applied on the outer contact wall above a predetermined threshold force.

Abstract: A collapsible cart may include a collapsible frame, a foldable shelf, and an interior support column. The collapsible frame includes a first frame portion and a second frame portion. The frame is configured to move between an open configuration and a collapsed configuration by relative translation between the first frame portion and the second frame portion. The foldable shelf extends between the first frame portion and the second frame portion. The foldable shelf is configured to fold to allow the frame to move from the open configuration to the collapsed configuration. The column transversely extends through a column slot defined by the foldable shelf. The cart further includes at least one column brace slidably coupling the frame to the column. The cart further includes at least one shelf brace slidably coupling the foldable shelf to the column.
