Abstract: A urine diverter may include a bowl to collect liquid waste. The urine diverter may include an aperture to direct liquid waste away from solid waste. The urine diverter may have an attachment to attach to a solid waste vessel, wall, or pole. The urine diverter may have a ventilation aperture to ventilate a composting or waterless toilet.

Abstract: A safety walker provides a strap that actuates to allow a person to enter into the safety walker and then raise the strap between their legs. The strap prevents ground level falls. The safety strap is actuated by a strap actuator that may pivot about a pivot attached to the movable support frame. The strap actuator may be locked into a secure position with the strap in an elevated position by a latch. The strap actuator may be coupled to a handle actuator by one or more linkages, or the strap actuator and handle actuator may be a one-piece rigid member that rotates about a single pivot on the moveable frame. A coupling member may extend between a left and right strap actuator proximal to the back end of the strap actuators and the safety strap may be attached to the coupling member.

Abstract: A hand tool includes a fixture having an adjustable working end and an opposing handle. The handle is rotated to the fixture. A transmission couples the handle to the adjustable working end, whereby rotation of the handle urges corresponding adjustment of the adjustable working end. The working end includes an end section, and a wrench insert rotated to the end section, or co-acting movable jaws mounted to the end section.

Abstract: A gravity oriented liquid dispenser includes a container that defines a chamber to contain a liquid. The container has a top including a liquid discharge mouth fluidly coupled to the chamber. The container is arranged about an axis that extends from the top to the bottom of the container. An air vent tube extends through the chamber from a first orifice in communication with the atmosphere at the top of the container to a second orifice near the bottom of the container in communication with the chamber. The first orifice is located between the liquid discharge mouth and one side of the container, and the air vent tube, including the first and second orifices, is located between the axis and the one side of the container and is convex along the axis toward the one side of the container from the first orifice to the second orifice.

Abstract: A portable secure anchor device may comprise a shaft having a proximal end, a distal end having a helical surface located at the distal end, and a housing which rotatably receives the proximal end of the shaft. The housing may include a locking mechanism in communication with an internal engagement mechanism connected to the proximal end of the shaft. The locking mechanism may have two or more positions, which either locks the internal engagement mechanism and allows the anchor device to be inserted or removed from the ground, or allows the engagement mechanism to freely spin and not be able to remove the anchor device from the ground.

Abstract: In various embodiments, a buoyancy engine can comprise a segmented chain comprising a plurality of linear segments. The segmented chain can rotate about a divider configured to separate a gas environment and a liquid environment, and can be configured to separate during linear vertical travel. Moreover, a trailing surface of a first segment of segmented chain can be configured to compress with a leading surface of a second segment to form a substantially solid surface in response to transitioning between the gas environment, and the liquid environment. As the segmented chain travels between the gas and liquid environments, a rotary motion is created which can be captured as electrical or mechanical energy.

Abstract: In accordance with various aspects of the present invention, a method and system for a buoyancy engine is presented. In an exemplary embodiment, the buoyancy engine includes a divider to separate a liquid environment from a gas environment, and a reservoir aperture in the divider. A rotating element, approximately opposite the reservoir aperture, provides tension to, and helps rotate, a segmented chain. The segmented chain is configured to form a solid inner surface when transitioning between the liquid and gas environments, but separate during vertical travel. As the segmented chain travels between the liquid and gas environments, a rotary motion is created which can be captured as electrical or mechanical energy.
