摘要:
A method for reducing stance energy is provided. The method including: storing energy during one or more periods of a periodic motion of a joint in which energy is absorbed by the muscles; at least partially returning the stored energy to the muscles during one or more periods in which the muscles are performing work; and producing a resisting moment at the joint in addition to a moment necessary for the storing. A method for rehabilitating muscles acting across a joint is also provided in which an amount of the storing is adjusted to provide a desired rehabilitative effect. Also provided is a method for enhancing performance of a physical activity where energy is absorbed by muscles associated with the motion and the stored energy is at least partially returned to the muscles during one or more periods of the motion in which the muscles are performing work.

A method for exercising muscles acting across a joint is provided. The method incl;uding: absorbing energy during one or more periods of a periodic motion of the joint in which the muscles are performing work; and at least partially transferring the absorbed energy to at least one of the muscles and another device during one or more periods of the periodic motion in which energy is absorbed by the muscles.

An apparatus for generating an electrical power upon an acceleration of the apparatus is provided. The apparatus includes: a piezoelectric member having at least a portion thereof formed of a piezoelectric material for generating an output power upon an impact; and a spring element configured to have at least one of a portion thereof and a portion attached thereto impact the piezoelectric material upon the acceleration.
摘要:
A projectile for deploying one or more sensors into an area is provided. The projectile includes a sensor platform disposed in the projectile. The sensor platform having: a sensor for detection of a condition within or proximate to the area; a processor and communication device operatively connected to the one or more sensors and to one or more of a remote station and at least one other sensor; and a power source for supplying power to at least the one or more sensors. Methods and apparatus for deploying the one or more sensors into the area are also provided.
摘要:
A method for at least slowing a vehicle moving along a surface is provided. The method including; providing one or more panels capable of extending above the surface; and deploying the one or more panels from the surface into a position extended from the surface.
摘要:
A method for slowing a vehicle traveling over a movable surface in a direction of travel is provided where the vehicle has a first wheel and at least a second wheel offset from the first wheel in a direction opposite to the direction of travel. The method includes: deploying the movable surface to an open position; moving the movable surface to a closed position due to the weight exerted on the movable surface by a first wheel of the vehicle as it travels over the movable surface; locking the movable surface in the closed position to convert at least a portion of a kinetic energy of the vehicle into potential energy to slow the vehicle; and redeploying the movable surface to the open position such that at least the moving can be repeated due to the weight exerted on the movable surface by a second wheel of the vehicle.
摘要:
A method of fire prevention/extinguishing for an aircraft runway is provided where the method includes: providing a supply of fire preventing/extinguishing chemical; disposing a piping system beneath a top surface of the runway and having an inlet in communication with the supply and an outlet in communication with the top surface; and delivering the fire preventing/extinguishing chemicals from the supply through the piping system and outlet to the top surface.
摘要:
A wrist strap is provided for use with gymnastic equipment having a bar held by a gymnast. The wrist strap including: a wrist band secured around the wrist of the gymnast; and one or more straps attached to the wrist band to form a loop around the bar.
摘要:
A method for preventing a gymnast from striking a portion of gymnastics equipment while performing a routine or practicing. The method including: attaching a member to one of a gymnast, either directly or through intervening members or to the portion of the gymnastics equipment; and the member preventing the gymnast from directly striking the portion of the gymnastics equipment.
摘要:
A manually operated impact tool is provided and includes: an impact mass; an anvil rotatably disposed relative to the impact mass; an input member operatively connected to one of the impact mass and anvil mass for imparting a relative rotation between the impact mass and the anvil; an output member connected to the other of the impact mass and anvil mass for transferring an impact to a fastener; and one or more elastic elements for storing potential energy upon the relative rotation between the impact mass and the anvil. Wherein conversion of the potential energy to kinetic energy causes the impact mass to impact the anvil and transfer of the impact to the output member.
