Abstract: Apparatus for protecting a user from impacts to the head. The apparatus includes a shell configured to receive a human head and a face mask coupled to the shell by a plurality of biasing mechanisms. The face mask is configured to reorient relative to the shell upon impact. The biasing mechanisms return the face mask to its original relative position after impact.

Abstract: Apparatus for protecting a user from impacts to the head. The apparatus includes a shell configured to receive a human head and a plurality of structures attached to the outer surface of the shell. Each structure includes an outer cell that absorbs direct impacts. Each structure is independently coupled to the shell with a respective assembly. The structures move independently of one another and are restricted to sliding tangentially along the outer surface of the shell. The assemblies each include a biasing mechanism that absorbs tangential impacts to the structure and returns the respective structure to its rest position. Thus, a user is protected from the concussive effects of a head-on impact and the rotational acceleration injuries of a tangential impact.

Abstract: A protector allows for the engagement and protection of a segment of an upright from an impact force by an external object and for absorbing and damping the resulting impact force. The protector comprises a protector body and a shim. The protector body allows engagement and positioning of the protector on at least a segment of the upright. The protector body is also partially constructed of an energy absorbing and damping material and having an outer surface and an inner surface. The outer surface is positionable to receive the impact force from the external object. The inner surface is positionable to abut the upright, when the protector is in engagement with the upright. The shim is least partially embedded in the protector body and provides increased structural support for the protector body. The shim also has a stiffness different than the stiffness of the protector body.

Abstract: A passive damper for earthquake hazard reduction includes an inner member received in an outer member, with an elastomeric material disposed in the gaps between the inner and outer member. The elastomeric material has at least a first and a second portion. The first portion is bonded or connected to both the inner member and outer member such that no slippage occurs between the members and the material. The second portion is not bonded or connected to at least one of the inner and outer members such that slippage may occur.

Abstract: A security device locks to a display structure such as a pegboard or slatboard to prevent the rapid removal of merchandise from the display structure by preventing the rapid removal of the entire security device. The security device includes a base and a rod with the base having locked and unlocked positions. The unlocked position of the base allows the security device to be removed from the display structure. The locked position of the base prevents the security device from being removed. The security device includes a lock that holds the base in the locked position. A key may be used to unlock the base. Customers may remove items of merchandise from the security device while the lock and base are in their locked positions.

Abstract: An anti-theft security device locks to a display board such as pegboard or slatboard to prevent the removal of the device from the display board and to prevent rapid removal of merchandise hanging from the device. Hooks are inserted in holes in the display board to connect the base of the device to the display board. The base includes an outer member and an inner member from which a pair of parallel rods extend outwardly away from the display board. The outer member is locked to the inner member to lock the device to the display board. The end assembly may pivot about one rod to an unlocked position to allow an employee to rapidly load items of merchandise onto the device.

Abstract: A mount with a first attachment member; a second attachment member spaced from the first attachment member; and resilient members joining the first and second attachment members, each of the resilient members having at least one void, the voids being collapsible under loading between a first open void condition where the mount has a first substantially constant stiffness, and a second collapsed condition where the voids are substantially closed, the mount having a second substantially constant stiffness when the voids are in the second collapsed condition.

Abstract: A security device is adapted to be locked to a display board, such as a pegboard or a slatboard, while displaying items of merchandise. The device includes a base that may be locked to the display board with a lock. The device further includes a rod adapted to extend from the base to carry items of merchandise. The lock of the device can only be opened with a key to prevent unauthorized removal of the device from the display board.

Abstract: A pneumatic tool is disclosed which includes vibration mounts to reduce the amount of vibration transferred to the user. The vibration mounts include a pair of support members and at least one resilient vibration isolator connecting the support member in a spaced relationship. A compressed air conduit passes through the support member openings but is only directly fastened to one of the support members.

Abstract: A vibration-reduced impact tool is disclosed wherein an elastomeric vibration isolator is fixedly attached within the tool housing and functions to absorb the vibration typically transmitted from the handle to the operator. The isolator is mounted between the cylinder assembly and the handle. As the tool is operated, a piston within the cylinder assembly is driven forward where it impacts with a tool accessory. The impact causes the piston and cylinder assembly to slide rearward in the tool housing, toward the handle. The elastomeric isolator absorbs the rearward movement of the cylinder assembly and thereby eliminates much of the vibration normally transmitted from the cylinder assembly to the handle and in turn, to the operator.

Abstract: An auxiliary torsional damper of the surface-effect type capable of damping torsional spikes which may occur during operational transition through the system's resonance frequency. Preferably, the auxiliary damper will be designed with a decoupling feature such that the damper will only provide auxiliary torsional damping for torsional oscillations which surpass a threshold amplitude. Since the surface-effect damper is deflection dependent, the larger the magnitude of the torsional spike, the larger the damping that will be applied thereto.
