This disclosure is directed to product merchandising systems that enable products to be swapped between base assemblies of different product merchandising systems and accommodate different charging/powering capabilities of the products. Product merchandising systems have puck assemblies comprising modular puck upper portions and modular puck lower portions. Various different products may be mounted on the modular puck upper portions, each with a different way of receiving power from the modular puck upper portions. Each modular puck upper portion can be detached from a modular puck lower portion of a product merchandising system and reattached to a modular puck lower portion of another product merchandising system without having to reconfigure a power connection to the product attached to the modular puck upper portion.

An interactive kiosk for displaying one or more accessories. The kiosk includes an accessory interface portion having: a) one or more accessory retainers configured to hold one or more accessories having one or more identifiers located thereon; b) one or more sensing devices configured to receive and/or transmit one or more identification signals to one or more identifiers to identify the presence and/or absence of one or more of the accessories from the one or more accessory retainers and relay one or more status signals; and c) one or more processors in communication with the one or more sensing devices configured to receive and analyze the one or more status signals from the one or more sensing devices.

An exhaust system for a combustion engine vehicle includes an exhaust pipe extending between an exhaust inlet disposed opposite an exhaust outlet. The exhaust inlet and exhaust outlet are in fluidic communication with one another. The exhaust inlet is configured to receive an exhaust gas produced by an internal combustion engine of the combustion engine vehicle. A second pipe has an air inlet extending from and connected to the exhaust pipe. The second pipe is configured to be in fluidic communication with the exhaust outlet. The air inlet is configured to receive an outside flow of air. The exhaust gas from the combustion engine vehicle and the outside flow of air captured by the air inlet when the combustion engine vehicle is moving forward are configured to be combined and to cooperatively exit out the exhaust outlet.

A watch stand configured to receive a smart watch including a face. The watch stand includes a receptacle configured to temporarily receive the smart watch within it with the smart watch positioned on edge and a body configured to magnify the face of the smart watch when the smart watch is viewed through the body.

A storage system includes a support bar that has a cavity connected to the external environment by a slot. One or more fixtures have shafts with a retainer at one end and an attachment at the other. The retainers rest on an internal surface of the support bar within the cavity and can be repositioned by sliding the fixture along the slot. The attachment may be a hook or other suitable attachment that supports stored objects for display in the external environment.

A shelf alignment guide system includes a first substrate that has a backside edge and a frontside edge, a bottom surface and a top surface; and one or more channels disposed on the top surface of the substrate, the one or more channels to hold eyeglasses; the one or more channels are curved to align with the eyeglasses.

A retractable display, storage and carrying case for necklaces includes an inverted-V-shaped frame, a torsion-spring-loaded tube rotatably suspended between the frame, a rectangular cloth sheet attached along one edge to the tube, with an opposite edge wrapped around a weighted rod to form a pocket on a front surface of the sheet. A plurality of jewelry hanging hooks are secured to an upper portion of the cloth sheet. One end of a necklace is attached to a single hanging hook, while the opposite end is tucked into the pocket. Much like a roll-up blind, the cloth sheet can be extended to a desired length by tugging on the weighted rod. Another tug will cause the roll-up mechanism to release and wind up the cloth sheet around the tube.
