Patent number: 11962343Abstract: Systems and methods for detecting fiber port availability in a fiber distribution hub and generating fiber port recommendations are presented. An exemplary method may include detecting, based at least on a fiber distribution record, one or more candidate ports in the fiber distribution hub; transmitting a first indication of a first selected port of the one or more candidate ports to a computing device; detecting, after transmitting the indication of the first selected port and in real time, that a termination unit associated with the fiber distribution hub has been disconnected; automatically updating the fiber distribution record such that the fiber distribution record is representative of an association between the termination unit and the first selected port; and generating, based on detecting that the termination unit has been disconnected, a second indication of a second selected port of the one or more candidate ports.Type: GrantFiled: September 29, 2023Date of Patent: April 16, 2024Assignee: FRONTIER COMMUNICATIONS HOLDINGS, LLCInventors: Carlo Nino Alba, John Valdez, Vincenzo Gaccetta

Patent number: 11389690Abstract: A fitness machine enabling several lunge and squat-style exercises comprises a frame that provides the basic structure of the machine. The frame includes a set of horizontal beams and a set of vertical beams creating a rectangular interior exercise space for a user to stand. A handle is included with each horizontal guide rail that slides forward and backward along the horizontal guide rail. The horizontal guide rail is movably connected between two of the vertical guide rails such that the horizontal guide rail freely slides up and down the vertical guide rails, ensuring that the horizontal guide rail maintains a parallel relationship with the floor throughout the entire range of motion during use. The handles and the horizontal guide rails significantly improve the user's balance during the exercise, eliminating unnecessary stress on the knees, hips, and lower back.Type: GrantFiled: September 13, 2019Date of Patent: July 19, 2022Assignee: KONDITION, INC.Inventors: Daniel Carlos Valdez, Ken Carter

Patent number: 11083928Abstract: An exercise machine. The machine includes a frame with front and rear upper support beams. Guide rails span between the two support beams and are connected thereto. Right and left handles are configured to slide back and forth along the length of the guide rails between the front and rear support beams. During operation of the machine, a user grabs the handles and moves them back and forth in a swinging motion that mimics traversing a set of monkey bars. The guide rails may be arranged in a non-parallel configuration to provide a more natural path for the user's hands during operation and to reduce unwanted stress on the user's shoulders by limiting handle movement along the path to accommodate a more comfortable range of motion.Type: GrantFiled: June 27, 2019Date of Patent: August 10, 2021Assignee: KONDITION, INC.Inventors: Daniel Carlos Valdez, Ken Carter

Patent number: 10717713Abstract: Novel compositions of matter based on homopiperazine precursor materials and forming a homopiperazine-based ligand are disclosed, along with suitable techniques and materials for the synthesis and utilization thereof. In particular various synthetic schemes and techniques for applying the disclosed compositions of matter as a decontaminating agent. The decontaminating agents include homopiperazine-based ligand-metal complexes that are particularly effective at neutralizing toxicity of nerve agents, pesticides, and other toxic organophosphorus-based compounds. In preferred approaches, the homopiperazine-based ligand-metal complexes act as catalysts to facilitate substitution of a leaving group of the organophosphorus-based compound with a functional group that does not permit the organophosphorus-based compound to inactivate acetylcholinesterase upon introduction of the organophosphorus-based compound to a living organism such as insects and mammals.Type: GrantFiled: September 19, 2018Date of Patent: July 21, 2020Assignee: Lawrence Livermore National Security, LLCInventors: Carlos A.
