Abstract: An optical apparatus for viewing one or more images including (i) an optical device for enhancing the one or more images and having a surface defining mechanical threads; (ii) a display device having a display for presenting information that is removably attached to the optical device, the display device including a surface defining mechanical threads for mating with the mechanical threads of the optical device; and (iii) a lock ring that is mounted to the mechanical threads of the optical device, said lock ring being positioned between the display device and the optical device, wherein the lock ring is rotatably positioned on the mechanical threads of the optical device to move toward and bear on a surface of the display device in order to either limit or prevent the display device from further rotation on the mechanical threads of the optical device.

Abstract: A collapsible storage device for use in a pickup truck bed including a rear panel; a lower panel hingeably mounted to a lower edge of the rear panel at a first edge; a first side panel hingeably mounted to a first side edge of the rear panel at a first edge; a second side panel hingeably mounted to a first side edge of the rear panel at a first edge; a first compression mounting mounted to the face of the first side panel such that the first compression mounting is compressed between the first side panel and a first sidewall of the pickup truck bed when the first side panel is in an open position; a second compression mounting mounted to the face of the second side panel such that the second compression mounting is compressed between the second side panel and a second sidewall opposing the first sidewall of the pickup truck bed when the second side panel is in an open position; a top panel hingeably mounted to a top edge of the rear panel at a first edge, the top panel resting on a top edge of the first and s
