  • Patent number: 11973366
    Abstract: Describes is a battery booster for jumpstarting a vehicle having an external battery. The battery booster comprising a set of electrical conductors, a power supply configured to supply a starting current to jump start the vehicle via the set of electrical conductors, a boost switch positioned in-line between the power supply and a set of battery clamps on one of the set of electrical conductors; and at least one processor configured to output a control signal to close the boost switch as a function of one or more parameters of the power supply, the external battery, or the vehicle. The set of electrical conductors are configured to couple with the external battery or with an engine that is electrically coupled with the external battery via the set of battery clamps. The set of electrical conductors comprises a positive electrical conductor and a negative electrical conductor.

  • Publication number: 20210212858
    Abstract: Intraocular drainage devices and methods of making intraocular drainage devices are disclosed. A disclosed intraocular drainage device includes a tube having a distal end and a body disposed proximal to the tube. A central inlet port is disposed on the distal end of the tube and extends lengthwise internally through the tube. A central outlet port is disposed on the proximal end of the body and extends lengthwise internally through the body. Multiple transverse inlet and outlet ports are coupled to the central inlet and outlet ports, respectively. The central and transverse inlet ports are configured to receive influent fluid from an anterior chamber of an eye and the central and transverse outlet ports are configured to output the influent fluid external to the anterior chamber of the eye. Intraocular drainage and core assemblies and methods of making intraocular drainage devices are also disclosed.

  • Patent number: 10945883
    Abstract: Intraocular drainage devices, intraocular implantation procedures, and inserter devices for intraocular implantation procedures are disclosure. A disclosed intraocular drainage device includes a tube having a distal end and a body disposed proximal to the tube. An inlet port is disposed on the distal end of the tube and configured to receive an influent fluid from an anterior chamber of an eye. An inlet fluid pathway is coupled to the inlet port and extends at least partially through the tube. A plurality of outlet fluid pathways extend at least partially through the body and branch from the inlet fluid pathway. A plurality of outlet ports are disposed on the body and coupled to the plurality of outlet fluid pathways. A disclosed inserter device for an ocular implantation procedure includes a handle, a needle, and a plunger. The needle is disposed on a distal end of the handle and configured to hold an intraocular drainage device. The plunger is coupled to the needle and disposed in the handle.
