Patent number: 8561333Abstract: A Snap N Place sign system and method for supporting a sign message includes a sign substrate associated with a number of rubber nipple fasteners and a lens. The sign message and the lens further include mounting holes placed at their corners for securely holding the sign message in association with the sign substrate and lens. The rubber nipple fastener can be pulled through the mounting holes in the lens utilizing a relatively low insertion force. The rubber nipple fasteners can be driven axially into the mounting holes in the lens with a flexible tab engaging the lens and flexing as they move through the hole in the lens. The rubber nipple fastener can be specifically designed such that the force required to install or push the rubber nipple fastener through the mounting hole is relatively low thereby facilitating ergonomic considerations. The Snap N Place sign system is capable of holding signs of a variety of thicknesses and sizes.Type: GrantFiled: January 21, 2010Date of Patent: October 22, 2013Inventors: Roxanna Meyers, Wesley Meyer, Leon Smith

Patent number: 8157396Abstract: A method, apparatus, and system are disclosed. The apparatus includes a shaft operable to be held by an entity and a housing extending from one end of the shaft and operable to allow multiple deterrents to be emitted there from. The housing includes a rotation member coupled to a rim portion of the housing and operable to rotate along a track portion within the rim portion. The apparatus further includes a transparent material coupled to the rotation member and operable to allow a deterrent to travel there through. The housing includes a light source coupled to the transparent material and operable to emit a light. Further, the apparatus includes a swivel meshed between the shaft and the housing and operable to allow the housing oscillate in an angular direction. Each deterrent is operable to obscure an image of the entity captured by filming equipment.Type: GrantFiled: December 15, 2008Date of Patent: April 17, 2012Inventors: Wilbert Leon Smith, Jr., Keelo Lamance Jackson

MULTI-LAYER SECURITY SYSTEM AND METHOD TO PREVENT UNAUTHORIZED ACCESS TO FUEL DISPENSER COMPARTMENTS
Publication number: 20070109068Abstract: The present invention provides enhanced security to internal components in a main access compartment of a fuel dispenser. Both a primary lock on a main panel, that secures the main access compartment, and a hidden second lock, hidden inside a lower compartment of the fuel dispenser, must be bypassed to gain access to the internal components, thus providing enhanced security. The lower compartment is also protected by a lock, which must be bypassed in order to gain access to the hidden second lock in an attempt to bypass the hidden second lock. This locking arrangement provides greater security than prior art methods since three locks, including a hidden lock, must be bypassed to breach security and gain access to the internal components in the main access compartment of the fuel dispenser.Type: ApplicationFiled: November 9, 2006Publication date: May 17, 2007Applicant: Gilbarco Inc.Inventors: Leon Smith, John McSpadden, Lester Ward, Dreama Sharpe, Jonathan DeLine -
