Patent number: 10533600Abstract: Fasteners such as bolts or nuts are locked by a ring and associated keys. The ring typically has a series of holes with the fasteners passing through these holes in the ring. The ring has an outer surface with studs extending upward therefrom. Typically one key for each fastener is placed adjacent to the ring after the fasteners are tightened against the ring in each hole of the ring. The key has a head opening which fits over a head of the fastener and keeps the fastener from rotating. The key also has a bore which fits upon the stud, with the stud preventing key rotation, and the key in turn preventing fastener rotation. A retainer such as a lock nut on a threaded stud or a snap ring in a grooved stud hold the key to the ring and keep the ring in position locking the fasteners.Type: GrantFiled: August 4, 2017Date of Patent: January 14, 2020Assignee: Hard Case PerformanceInventors: Ian Jackson, Daniel Martell, Justin Church

Patent number: 9112258Abstract: An efficient electrically small circularly polarized SATCOM antenna includes two crossed half loops which are encapsulated by a capacitive cage structure which acts as an internal matching network for the antenna. The cage structure induces two orthogonal electric fields which are 90 degrees out of phase, which produces omni-directional circularly polarized radiation patterns. The gain and impedance performance surpasses that of prior art of similar size.Type: GrantFiled: June 12, 2012Date of Patent: August 18, 2015Assignee: The United States of America as represented by the Secretary of the NavyInventors: Justin A.

Patent number: 9088059Abstract: Methods for establishing metamaterial transmission line (MTM TL's) for a phased array antenna can include the initial step of defining a defining a Composite Right/Left Hand (CRLH) CRLH unit cell architecture. A family of unit cells using CRLH TL microstrip architecture can be constructed so that each of the CRLH unit cells have the same physical length, but different cell phases and cell phase slopes. To do this, the stub length of each CRLH unit cell can be varied. Once the family of CRLH unit cells is constructed, different numbers of different CRLH unit cells from the family can be combined with different numbers of conventional right hand TL's, which results in TL's for a phased array antenna that each have the same overall phase and overall phase slope not only at the design frequency f0, but over the entire design frequency band for the antenna.Type: GrantFiled: May 28, 2013Date of Patent: July 21, 2015Assignee: The United States of America, as Represented by the Secretary of the NavyInventors: Justin A. Church, John Meloling, John D. Rockway
