Abstract: A panel retention device, a panel mounting system, and a panel assembly each including an adjustable flange in threaded engagement with a compression plate. In one version of each of the panel retention device, the panel mounting system, and the panel assembly, the compression plate is in indirect threaded engagement with an externally threaded adjustable flange through an internally threaded disk extending from the compression plate. In another version of each of the panel retention device, the panel mounting system, and the panel assembly, the compression plate is in direct threaded connection with the an externally threaded adjustable flange threaded into a threaded opening in the compression plate.

Abstract: A system and method for displaying product information on the product display. The system including a server positioned at a first location. The server is provided that is configured to receive an input and transmit a data package in response. The input to the server includes product data. A first plurality of mobile devices is positioned at a second location. The second location is different from the first location. The first plurality of mobile devices each has a first display and a second processor. The second processor is responsive to receiving the data package and displaying the product data on the first display in response to receiving the data package.

Abstract: A panel retention device is provided and includes a compression pad, a compression plate, a threaded disk, and an adjustable flange. The compression pad has a rectangular cross section and includes a plate opposing surface. The compression plate has a rectangular cross section and includes a pad support surface facing the compression pad and a disk support surface. The threaded disk extends from the disk support surface, and the adjustable flange is removably threaded onto the threaded disk.

Abstract: A fluid detector for determining a presence of a fluid within a container includes a piezoelectric element that outputs a first ultrasonic signal in response to an input electrical signal and a lens with an upper portion and a lower portion. The piezoelectric element is coupled to the upper portion of the lens so that, when the lens is disposed adjacent the outer surface of the wall such that the lens is intermediate the piezoelectric element and the wall, the lens focuses the first ultrasonic signal toward the wall so that the first ultrasonic signal enters the wall.
