Patent number: 11385097Abstract: Systems and methods related to optical measurement of vibrations experienced by components may include a light source, a reflector associated with a component to be measured, and an optical sensor. In addition, the systems may include one or more fiber optic cables to transmit emitted light between the light source and the reflector, and to transmit reflected light between the reflector and the optical sensor. The optical measurement systems may enable detection of a large dynamic range of vibrations experienced by components or systems, and may also enable determinations related to high cycle fatigue and other stresses. Further, the optical measurement systems may be integrated into systems having various components to be measured, thereby enabling continuous, in-situ measurement of vibrations and health, as well as continuous monitoring and adjustment of operations of such systems.Type: GrantFiled: May 31, 2018Date of Patent: July 12, 2022Assignee: Amazon Technologies, Inc.Inventors: Noah Allstot, Dominic Scott Lebaron, Bradley Leonard, Ryan Jeffrey Aalund

Patent number: 7249715Abstract: A key ring card wallet for holding key ring cards such as club membership cards, shopping club cards, and small credit cards is made of a front sheet, a back sheet, and the sheets are connected by a folding line, a seam or a hinge. Each of the sheets has means for fastening itself to the other. Upon being folded along the fold line, the two sheets form a jacket for holding the cards inside and also provide a common hole through which a key ring passes. In such a key ring card and wallet assembly, each of the key ring cards is allowed to rotate around the loop of the key ring so that the key ring cards can get out of or retract into the jacket. Key ring cards can be added or removed from the assembly without removing the wallet from the key ring.Type: GrantFiled: September 10, 2005Date of Patent: July 31, 2007Inventor: Bradley Leonard Lambright
