Abstract: Various embodiments are disclosed for automated gait evaluation for retraining of running form using machine learning and digital video data. At least one machine learning routine is executed using video data to generate positional data of anatomical landmarks of a human or bipedal non-human subject in a video. Gait metrics and/or characteristics are determined for multiple stages of a gait cycle based on the positional data. An optimal gait cycle for a given body part or gait metric of the subject is determined and may be adjusted based on at least one covariable over time. A suggested change to movement patterns of the subject at specific timepoints or stages of the gait cycle that minimize a difference between the gait cycle of the subject and an optimal gait cycle are shown on a display device.

Abstract: A mounting apparatus for vehicle suspension ball joints that are firmly affixed for operation, are easily adjustable in a generally vertical direction for precise tuning of suspension geometry for dynamic performance in multiple axes using an array of cylindrical shims tuned to match fastener distance and height with a socket that has mounting bolts that engage a scalloped cap.

Abstract: Bladders/containers designed to hold a meaningful amount of material (in any state: solid, liquid or gas) to conductively absorb heat from the human body. In addition, the material may be consumed by the user wearing the bladder/container, thus providing a source of hydration for the user. The bladders/containers would also enhance impact and/or ballistic protection of the user.

Abstract: A portable device receives power from a battery of a vehicle when connected to the vehicle via a connector in the vehicle. The portable device determines whether an engine of the vehicle is running and a speed of the vehicle if the engine is running. The portable device clears fault codes of ECUs if the engine is not running. The portable device resets parameters of an ECU controlling an exhaust system of the vehicle to default values if the portable device remains connected to the vehicle for a predetermined time period after sending clearing the fault codes. If the engine is running and that the speed of the vehicle is zero, the portable device initiates a forced regeneration of a diesel particulate filter of the exhaust system.

Abstract: Flow control mechanisms control the direction and flow rate of synthesis reagent through one or more synthesis reaction vessels for automated solid phase synthesis. Selectable, known, and reproducible positive or negative pressure differentials (?5 to +10 psi) accomplish controlled, bidirectional (forward and reverse) flow of synthesis reagents through synthesis media contained within the reaction vessels. Venturi-based vacuum apparatus, valves, electronic pressure regulators and compound digital pressure gauge, can be added to automated solid phase synthesis instruments to provide, control, and monitor known, selectable, reproducible negative and positive pressures to one or both valve sealable and un-sealable ends (inlets and outlets) of the reaction vessel as needed to generate and reverse said pressure differentials between the opposite ends of said synthesis reaction vessels, yielding controlled forward and backward flows of synthesis reagents through the synthesis media.

Abstract: An armor plate carrier cummerbund attachment mechanism that is stretchable, adjustable, and or removable. The attachment mechanism allows a plate carrier to be adjusted for size without interfering with the functionality of a MOLLE (Modular Lightweight Load carrying Equipment) field.

Abstract: A mechanism for securing tubes in a fixed position is described wherein a body to which a tube is to be fixed has at least one smooth bore hole extending therethrough. A tube has an inner diameter accommodating fluid flow and an outer diameter passing through the smooth bore hole in slip fit relation with the smooth bore of the hole. A threaded hole with helical grooves is parallel to the smooth bore hole and located such that its grooves intersect the diameter of the smooth bore hole. A set screw made of a tougher material than the tube has threads that will seat in the threaded hole in a manner such that advancing the set screw scratches the outer diameter of the tube to a depth wherein the set screw retains the tube in place without deformation of the inner diameter of the tube whereby fluid flow in the tube is not affected by advancement of the set screw while the tube is retained in place by the set screw. The invention can connect tubes in all sorts of patterns with many center-to-center tube distances.

Abstract: A hollow spherical projectile is constructed from a plurality of curved structural segments and has a plurality of openings. The projectile can be fired by a conventional paintball marker with a high degree of ballistic accuracy. The projectile is reusable and is fabricated from a flexible and resilient material. The outer surface of the projectile exhibits low friction, achieved by the material itself or by having a low friction coating applied. The projectile possess and transmits less kinetic energy than a conventional paintball and therefore inflicts less pain and damage upon impact. Fabrication can be accomplished by 3D printing, or molding as a single seamless piece, or as a plurality of pieces which are then assembled.

Abstract: A self-contained electrically powered and fully submersible swimming pool vacuum includes a vacuum head having a housing with an elongate vacuum mouth at a bottom end, a discharge opening at an opposite top end and a thrust channel extending therebetween. An electrically powered motor is supported within the thrust channel and drives a propeller to create a thrust through the housing from the vacuum mouth through the thrust channel and out from the discharge opening. A catch bag is removably secured to the top discharge opening for collecting debris sucked through the vacuum mouth. The vacuum includes an onboard power supply, a smart power switch for driving the motor at different speeds and for detecting and clearing motor jams, all contained within a watertight housing fixed to an outer side of the vacuum housing. In one embodiment, the onboard power supply is a lithium ion rechargeable battery.

Abstract: A system for remotely controlling a plurality of subsystems of a vehicle comprises a processor and a memory storing instructions.
