Abstract: A pulse free fuel pump device designed to provide smooth, continuous fuel flow without pressure pulses is disclosed. The device includes a housing, a first impeller operating at a relatively low RPM to initiate fuel pressurization, and a second impeller operating at a relatively higher RPM to achieve final high pressure. A stator is positioned between the impellers to stabilize the fuel flow, and a rotor, connected to both impellers via a shaft provides synchronized rotation and reduces pulsation. The device is integrated into a fuel system comprising a fuel tank, a fuel filter, and a high-pressure fuel rail distributing fuel to injectors. The method of operation involves installing the pump in the fuel supply line, connecting it to the turbine's electrical system, and dynamically controlling rotor speed based on fuel demand, ensuring consistent, pulse-free fuel delivery to the combustion chamber.

The mating ends of the signal contacts and the ground shields form a hermaphroditic mating interface for mating with the hermaphroditic mating electrical connector assembly.

Abstract: A hose coupling device is disclosed. The device is an improved hose coupling that allows the hose to move more freely than a traditional coupling. The hose coupling device comprises a sleeve component with a female hose thread on one end and a male hose thread on the other end. The sleeve component further comprises a bearing above and below an O-ring water seal. The hose coupling component rotates independently from the hand nozzle component and eliminates the twist/kink of the hose when walking around spraying water.

Abstract: A circuit board assembly includes a circuit board and an electrical connector having a connector housing holding contacts in a contact array. The connector housing has a mating end configured to be mated with a mating electrical connector in a mating direction. The electrical connector has cables terminated to the contacts and extending from a cable end. A connector mount is used to locate the electrical connector relative to the circuit board. A bracket is coupled to the mounting surface of the circuit board. A biasing member is coupled to the bracket and the mounting feature and is compressible along a compression axis parallel to the mating direction to allow the electrical connector to float in the mating direction relative to the circuit board.

Abstract: A novel clamp device is described herein. The device is a modified clamping style for the CV boot of a Porsche and other vehicles. The device is comprised of an aluminum and tubular clamp for the CV that allows for maximum accessibility of the angle. Specifically, the aluminum clamp is segmented into three equal parts with different diameters to accommodate different drive shafts. Silicone or grease can be used to hold the parts in position for assembly. On one end is a groove for the clamp to sit, while the other side features an inside bore located where the clamp area of the boot sits. When the band is in position, it locks the aluminum pieces in position to allow full travel of the boot with no abrasion damage.

Abstract: A pool skimmer is disclosed that comprises a base component comprised of a bar with a U-shaped net component secured to it. The net component measures two to three feet wide and is comprised of fine, stainless-steel microns. A flexible, telescopic handle is then secured to the base component. The base component is placed inside of the swimming pool and comprises a flotation system to allow the device to be positioned halfway above the water level. The U-shaped net allows a user to capture small bugs, leaves, or other unwanted debris within the swimming pool quickly and efficiently.

Abstract: A vibrational cup device is disclosed that prevents a drink from spilling as ice readjusts within. The vibrational cup device comprises a base component positioned on a bottom portion of a cup and sealed with O-rings. The base component is removable and comprises a rechargeable battery, a micro circuit board, a vibrational motor, a USB port with plug, and a motion sensor that tells the device when the cup is at a 45-to-60-degree angle. At these angles, the vibrational motor would engage for approximately 10 seconds to help break up the ice in the cup or to level out the ice to prevent the sudden release of ice cubes, thus spilling part of the drink.
