A portion of ankle movement can be harnessed into stored energy that can be released for various purposes, such as to assist in movement or to charge a battery. This harnessing can be achieved in various manners. In one example manner, an offset pulley component can transfer ankle movement to a generator in a shoe insole. In another example manner, a slider can cause a brace arch to match an ankle arch such that the movement is appropriately harnessed.

A footwear system can employ a brake and/or a clutch, such as a one-way clutch, to convert human motion into usable electricity. The brake and one-way clutch can be used together, such as on opposite ends of a spring. During a storage phase, the brake can be engaged and the one-way clutch disengaged so the spring stores an energy. After the storage phase, the brake can be removed to initiate the release phase since the brake is not stopping the spring, but the one-way clutch allows the stored energy to be released.

A wearable system, such as a footwear system, can employ a generator. The generator can be powered by human movement, such as movement of knee as a person walks or runs. When the knee resets, it can be desirable to have a relatively equal gear ratio to achieve near natural movement. Conversely, it can be desirable to have a high gear ratio when the knee pushes off to achieve high generator rotation to produce a high amount of power. This can be achieved with employment of a wearable planetary gear set configuration In practicing this wearable planetary gear set, torque can be provided from the source (e.g. human ankle joint) when power negative and not at other times during a movement cycle, meaning energy can be harvested from the walking motion without inducing additional burden to the device wearer.

A wearable system, such as a footwear system, can employ a generator. The generator can be an electro-mechanical generator with a portion that spins to create an electricity. The portion that spins can be spun in such a manner that it does not stop, but instead a next spin beings before a previous spin completes. This can repeat until the generator reaches a terminal velocity.

A movable standing base for parasols, display boards, flagpoles and the like comprises a weight part having, firmly attached at the bottom side thereof, at least three, preferably four steering rollers, and it further comprises attachment elements for a parasol, for a display board, for a flagpole or for any other objects to be set up, and a plurality of preferably four lowerable blocking feet. In order to improve ease of handling without loss of stability, the blocking feet are connected to each other in the edge region of the weight part by two bridge girders arranged opposite to each other and a middle yoke and are anchored to the weight part in a substantially parallelogram shaped lowerable manner by two pivot levers. A tensioning lever is disposed resting on the middle yoke, and a pressure element leads to a blocking pedal at the upper side of the standing base.

A brake for use with a shock testing machine, the brake including: a brake material for generating a frictional force to stop a test platform when the brake material is urged against an opposed braking surface; links for rotatably connecting the brake material to the test platform; a biasing spring to bias the brake material towards the braking surface; a restraint mechanism for restraining the braking material, against a biasing force of the biasing spring, in a retracted position where the braking material is separated from the braking surface; and a release mechanism for releasing the restraint of the release mechanism to bias the brake material against the braking surface; wherein the links are configured such that relative movement between the brake material and braking surface while the brake material and braking surface are engaged causes a frictional force between the brake material and braking material to increase.

A chassis of a transportable device including a base structure, four casters arranged thereon, four lowerable and raiseable support feet also mounted on the base structure, and a hydraulic support foot actuating device. The hydraulic support foot actuating device has a reservoir (1), a pump (2) manually operable by hand or foot, four support foot linear actuators (3) and a purely hydro-mechanical pipe and valve arrangement (4) which connects the reservoir (1), the pump (2) and the linear actuators (3) to one another. Therein, by means of hydraulic fluid delivered by the pump (2) from the reservoir (1) the two support feet assigned to two primary linear actuators (3a) can be fully extended until a mechanical stop is reached while raising the base structure by first applying pressure to the two primary linear actuators (3a) before applying pressure to the two other, secondary linear actuators (3b).
