Patent number: 11999055Abstract: A gripping device is provided for grasping an object. The device includes a frame, an axial threaded screw, an actuator, an armature, a plurality of links, and a plurality of arms. The frame has proximal and distant ends to hold the screw. The actuator connects to the screw at the proximal end. The armature threads onto the screw. The links radially extend from the armature. Each link terminates in a ball tip. Each arm includes a lever bounded by a proximal hinge and a distal claw. The lever contains a plate to slide therealong. The plate has a socket that receives the ball tip. The hinge pivotably connects to the proximal end of the frame. The actuator turns the screw, thereby translating the armature aft towards the distal end of the frame. The armature carries each link to pull its ball tip aft, thereby causing each arm to radially contract its claw around the object.Type: GrantFiled: August 9, 2021Date of Patent: June 4, 2024Assignee: United States of America, as represented by the Secretary of the NavyInventor: Andrew M.

Patent number: 11993615Abstract: Tunable thermochromic materials comprise a metal salt with a varying proportion of two different anions and an organic ligand. Partial substitution via doping during the initial synthesis with a macro-structurally similar (generating an isostructural material) yet chemically different anion creates a material with altered thermochromic properties. For example, in bromide-doped bis(N,N?-diethylethylenediamine)nickel(II)) tetrafluoroborate; both the tetrafluoroborate (BF4-) and bromide (Br—) derivatives are isostructural. Substitution of BF4- for Br— causes a decrease in the materials' thermochromic transition temperature by approximately 10° C.Type: GrantFiled: October 7, 2022Date of Patent: May 28, 2024Assignee: The Government of the United States of America, as represented by the Secretary of the NavyInventor: James August Ridenour
