  • Patent number: 11981429
    Abstract: Systems, devices, and methods including: a latching mechanism comprising: a first latch configured to attach to a door of an unmanned aerial vehicle (UAV); a second latch configured to attach to a portion of the UAV distal from the first latch; a string connected between the first and second latch, where the string secures the door shut; at least two radio modules in communication with a ground control station; and at least two burn wires in contact with a portion of the string between the first latch and the second latch; where current from a backup battery passes to at least one burn wire when the burn signal is received, where the burn wire causes the connection between the first latch and the second latch to be broken and the door of the UAV is separated from the UAV, and where the parachute is deployed when the door of the UAV is separated from a rest of the UAV.

  • Publication number: 20210251959
    Abstract: Methods for increasing the encapsulation or incorporation of Sunitinib into polymeric matrices have been developed. The resulting formulations provide for more sustained controlled release of sunitinib or other inhibitors of JNK signaling, which bind to DLK. Increased loading is achieved using an alkaline solvent system. The pharmaceutical compositions can be administered to treat or reduce neuronal death due to elevated intraocular pressure. Upon administration, the sunitinib or other inhibitor is released over an extended period of time at concentrations which are high enough to produce therapeutic benefit, but low enough to avoid unacceptable levels of cytotoxicity, and which provide much longer release than inhibitor without conjugate.

  • Patent number: 9273529
    Abstract: A pulse generator comprises a stator coupled to a housing and a rotor that is rotatably disposed within the housing. An annulus is formed between the rotor and the stator. An inner bore is formed through the rotor. One or more outer flow ports provide fluid communication between the annulus and the inner bore. A retrievable valve assembly is rotationally coupled to the rotor and at least partially disposed within the inner bore. The retrievable valve assembly includes a rotary valve member having one or more primary flow ports. A fluid flow path is periodically formed by the one or more outer flow ports, the annulus, and the one or more primary flow ports as the rotor rotates.

  • Patent number: 5617212
    Abstract: The invention relates to apparatus for open-path gas monitoring and is particularly concerned with measuring the opacity of stack gases. Single and double pass systems to provide an optical across the stack, are known, but to provide meaningful data, gain compensation is required to deal with temperature variations and the possibility of ageing of electronic components.
