摘要:
A method for harvesting energy from a high-G acceleration of a munition. The method including: proving a vibrating mass-spring unit in a housing of an energy harvesting device; and reducing an effective acceleration on the mass-spring unit by one or more of: offsetting the vibration of the mass-spring unit with respect to a direction of the high-G acceleration; biasing a mass of the mass-spring unit in a direction having at least a component in the direction of the high-G acceleration; limiting a vibration deflection of at least a portion of the mass-spring unit in the direction of the high-G acceleration; or limiting an amount of vibration of the mass-spring unit in a direction offset from the direction of the high-G acceleration and removing such limit after the acceleration.

A buoy for generating electrical energy from an upward heave resulting from a passing wave is provided. The buoy including: a body; a first device associated with the body to which a motion of the heave is transferred; and a second device associated with the body to which the motion is intermittently transferred from the first device. A buoy is also provided for generating electrical energy from a pitch/roll resulting from the passing wave where the first device is associated with the body to which a motion of the pitch/roll is transferred and the second device is associated with the body to which the motion is intermittently transferred from the first device.
摘要:
A device for providing electrical energy in a submunition of a projectile upon an expulsion acceleration of the submunition from the projectile, the device including: at least one elastic element and a mass connected to the at least one elastic element such that a firing acceleration of the projectile deforms to store mechanical energy in the elastic element; and a mechanism for locking the elastic element in the deformed position and unlocking the elastic element due to the expulsion acceleration to vibrate the at least one elastic element and mass and apply a cyclic force to at least one piezoelectric element to convert the stored mechanical energy to electrical energy.
摘要:
A power supply for providing electrical energy to a self-destruct fuze for submunitions contained in a projectile. The power supply including: a movable mass; at least one elastic element attached to the mass at one end for storing mechanical energy upon a firing acceleration of the projectile; at least one piezoelectric element attached to another end of the at least one elastic element for converting the stored mechanical energy to electrical energy upon the firing acceleration to vibrate the mass and at least one elastic element to apply a cyclic force to the at least one piezoelectric element; and a self destruct fuze for detonation of the self destruct fuze upon receiving the electrical energy.
摘要:
A method for igniting a thermal battery upon a predetermined acceleration event. The method including: rotatably connecting a striker mass to a base; aligning a first projection on the striker mass with a second projection on the base such that when the striker mass is rotated towards the base, the first projection impacts the second projection; and preventing impact of the first and second projections unless the predetermined acceleration event is experienced.
摘要:
A generator including: a member having a cable wound thereon, the cable having a free end; a spring for storing energy as the cable is unwound from the member by pulling on the free end; and an electromagnetic generator operatively connected to the member such that rotation of the member is transferred to an input side of the electromagnetic generator after the cable is unwound from the member and the stored energy in the spring turns the member.

A thermal battery including: a housing having a first compartment and a second compartment; a thermal battery housed in the first compartment; and an inertial igniter housed in the second compartment; where the first and second compartments are separated by a rigid member.
摘要:
An electrical switch including: a body; a mass element; a spring element attached at one end to the body and at another end, at least indirectly, to the mass element; and an inclined surface upon which the mass element moves from a resting position to an all-fire position. The inclined surface being inclined with respect to a firing setback acceleration. When the body experiences the firing setback acceleration, the mass element travels at least across the inclined surface against a force of the spring element to contact an electrical contact and close a circuit.
摘要:
A device for enabling safe/arm functionality in a gravity dropped weapon detachably connected to an airframe where the device includes: an elastic element disposed in a shell of the weapon; a releasable connection between the weapon and the airframe to release one or more of a stored and generated energy in the elastic element; and a piezoelectric member connected to one end of the elastic member for converting the one or more of the stored and generated energy to an electrical energy. The releasable connection can include: a link having a movable connection for movement of the link relative to the shell between a first position constraining the elastic element from movement and a second position releasing the elastic member to generate the electrical energy; and a lanyard for tethering the link to the airframe such that the link is moved to the second position upon the weapon being released from the airframe.
摘要:
A method of igniting one of a pyrotechnic material and primer during or after an all fire setback acceleration. The method including: positioning a mass element along an inclined surface; biasing the mass element in a direction into the inclined surface such that the mass element traverses the inclined surface upon the all fire setback acceleration against the biasing; drawing the mass element toward one of a pyrotechnic material and primer with the biasing after the mass element traverses the inclined surface. The method can further include delaying the drawing until the mass element experiences a set forward acceleration. The delaying can include drawing the mass element into a delay well after the mass element traverses the inclined surface and drawing the mass element across a delay wedge when the mass element experiences the set forward acceleration.
