The systems, methods and apparatuses described herein provide a footwear hydraulic system for harvesting power generated by pressing a foot on a surface and providing a cushion for the impact. In certain aspects, a hydraulic system for a footwear may comprise at least one chamber with a first and second compartments separated by an elastic membrane. The first compartment may be filled with gas and the second compartment may be filled with liquid. The gas may provide impact cushion and transient energy storage, and the liquid may pressured to push a generator to produce energy. The pressure may be generated by pressing the footwear on a surface and/or the elastic membrane of the chamber trying to restore its shape.

Among other things, an integrated portable energy conversion mat is to be installed at a pavement surface over which a car or truck is to pass. The mat has a width at least as wide as the distance between the outermost edges of the treads of the tires located at an axle of the car or truck. The mat has a top surface over which the tires of the car or truck are to pass. The mat includes a sealed enclosed space housing and energy conversion system. The energy conversion system includes two sets of channels that extend along a length of the mat and contain hydraulic fluid under pressure. An energy converter converts energy carried by the hydraulic fluid in response to the tires of the car or truck passing over the top surface into electrical energy. An electrical port is coupled to the energy converter and exposed at an outer surface of the mat. The two sets of channels are spaced apart across the width of the mat by a distance that corresponds to the distance between the treads of the tires located at an axle of the car or truck. The energy converter is located within the sealed enclosed space of the mat and in the portion of the mat that is between the two sets of channels.

The present invention relates to a flooring system for generating electricity from users as they walk. A flooring system (1) for generating electricity, comprising: a plurality of generators (100), each generator (100) having a support, each generator being arranged to generate electricity from linear motion of the support in a first direction; and a plurality of tiles for supporting one or more people, wherein each support supports a plurality of tiles.

Motion of a body segment is assisted when the body segment is moving in a positive power mode but not when it is moving in a negative power mode. When the motion of the body segment is cyclical, for example during walking, assistance to the body segment is switched on and off throughout the cycle to correspond to positive and negative power modes respectively. Energy used to assist the body segment may be harvested from prior motion of the body segment, either in prior cycles and/or when the body segment is moving in a negative power mode. The energy used may also be harvested from other body segments. Assisting motion of a body segment may be used to reduce the metabolic cost of locomotion, or to reduce exertion, when walking, jogging, running or sprinting.

A power generation system is disclosed herein. The power generation system includes two or more tiles and at least one generator. Each tile of the two or more tiles is configured to house one or more solar cells. The at least one generator apparatus couples each of the two or more tiles together at a vertex of each tile. The at least one generator apparatus is configured to harvest mechanical energy as mass traverses each tile of the two or more tiles.

The present invention relates to a flooring system for generating electricity from users as they walk. A flooring system (1) for characterising a footstep (2), comprising: a plurality of tiles (200) for supporting one or more people; and a plurality of sensors (100x, 100y, 100z), each sensor (100x, 100y, 100z) arranged to generate a signal representing a force applied thereto, wherein each tile (200) is supported by at least three sensors (100x, 100y, 100z), the flooring system (1) further comprising a data processing system (1001) in communication with each sensor (100x, 100y, 100z) for receiving the signal generated thereby, wherein for each tile (200): the data processing system (1001) is arranged to produce output data by comparing the signals received from the sensors (100x, 100y, 100z) supporting that tile (200) to estimate the location of a footstep (2).

A mechanism has four connected links to mimic the motion of a knee joint. A lower link is oriented towards the vertical. A leverage ratio between flexion of the knee and relative angular displacement of certain links in the mechanism remains fairly steady over much of the range of motion of the mechanism. The mechanism may be used to drive an energy harvesting gearbox with steadier and more efficient energy harvesting at deep flexion, as well as with quieter operation.

Various embodiments related to a recumbent therapeutic and exercise device are provided herein. The recumbent therapeutic and exercise device includes a frame; a hand crank system coupled to the frame, the hand crank system including a hand crank rotatable by a user, wherein the hand crank is movable in a substantially vertical plane closer to and further from a support surface for the frame; and a foot crank system coupled to the frame, the foot crank system including a foot crank rotatable by the user, wherein the foot crank is movable in a substantially horizontal plane relative to the support surface for the fame.

The present invention is able to extract significant amounts of energy from a user who is walking or running while remaining discreetly hidden near an area of the body where many people already carry things (e.g. wallet, smartphone, keys). The user benefits by keeping their device(s) charged for a longer period of time without the need for external batteries. In addition, the present invention encourages an active lifestyle, which has been shown to promote good health and reduce the risk of many diseases.

A power generation system including a partially enclosed container assembly housing a plurality of spherical balls at a container height disposed above a ground surface, each of the plurality of spherical balls having a ball weight. The power generation system also includes a conveyor assembly with a conveyor-drive system having a plurality of ball-catch members. The conveyor assembly includes a proximal end coupled to the container assembly, a distal end, and a conveyer length separating the proximal and distal ends. The conveyor assembly spans downwardly from the container assembly at a location below the container height and is operably configured, via the ball-catch members of the conveyor-drive system, to transport the spherical balls. A generator is operably coupled to the conveyor-drive system and is operably configured to produce electricity. The power generation system also includes a lift assembly having a lift-drive system spanning from a ball-receiving position to a ball-dispersing position with a height disposed above the ground surface that is greater than the container height. The lift-drive system includes a ball-platform sized to hold the plurality of spherical balls and a platform operably coupled to the lift-drive system that is sized to hold a plurality of users. The platform includes a raised position and a lowered position along a lift translation path. The raised position includes a height disposed above the ground surface that is greater than the container height. Movement of the platform of the lift-drive system along the lift translation path is operably configured to move the ball-platform of the lift-drive system along ball-platform translation path to transport the spherical balls to the ball-dispersing position.
