A framing system includes a first connection assembly that engages with a substrate. The first connection assembly includes a first connector and a track. At least one spring flange defined by the first connector engages with a fastener positioned along the substrate to maintain the first connection assembly in a fixed position relative to the substrate and to interconnect the substrate with the track. The framing system further includes a second connection assembly defining a second connector engaged to a stud. The second connection assembly engages with the first connection assembly to interconnect the stud with the track.

An improved shock isolating mounting comprising at least three substantially U-shaped leaf spring members, each leaf spring member comprising at least two leafs arranged to define a space therebetween. In one arrangement, the respective at least three substantially U-shaped leaf spring members are arranged in an array having a substantially equal angular spacing between adjacent spring members.

A clamp including: a holding portion and a fixing portion, wherein the fixing portion includes: a base, a support shaft that extends from the base in a direction away from the holding portion, a lock that is provided at a leading end of the support shaft and is formed to be able to be locked to the fixed portion, a spring that is provided in a surrounding region of the support shaft between the base and the lock, and is formed so as to be extendable in a direction in which the support shaft extends, and a vibration suppressor provided between two opposing surfaces of the spring that are adjacent to each other in a direction in which the support shaft extends and face each other.

Provided are assemblies, comprising: a first leaf spring; a second leaf spring; and at least one component; the first leaf spring and the second leaf spring being superposed over a first end of the at least one component so as to exert first and second forces, respectively, through first and second regions of the component. These assemblies are useful to apply different forces to a stacked assembly where a cross section of a component of the assembly comprises materials of different Young's moduli within that cross section, thereby compressing different regions of the component with different forces.

A variable stiffness spring assembly includes first and second members made of a first material and separated by a gap along at least a portion of their lengths, and one or more layers made of a second material disposed in the gap. The variable stiffness spring assembly can be incorporated into or take the form of a limb support assembly, such as a prosthetic foot. The second material disposed between the first and second members is rate-sensitive or speed-dependent, such that the material exhibits different properties when the user of the prosthetic foot is walking at high or fast walking speeds compared to low or slow walking speeds. The prosthetic foot can exhibit high damping and energy absorption, and therefore stability, at slow speeds, and high energy return at faster speeds.

A vibration isolator and method of assembly utilize “flex circuits” to provide both vibration/shock isolation and integrated electrically isolated conductive paths to support lightweight devices (<100 grams) such as crystal oscillators, IC chips, MEMs devices and the like. Each flex circuit includes a least one polymer layer and at least one of the flex circuits includes at least one patterned conductive layer. The isolator may be integrally formed from a stack of polymer layers and patterned conductive layers to provide the plurality of flex circuits, platform and connectors. Most typically, flex circuits are Type 4 in which the multiple polymer layers have a loose leaf or bonded configuration. Flex circuits are easy to produce in large quantities at low cost with standardized and repeatable performance characteristics.

A spring leaf and a manufacturing method of making the spring leaf are disclosed. The spring leaf is installed in a casing to replace a butting part on the casing. The spring leaf includes at least a pole, at least an elastic connector, at least an elastic arm, a contact part which contacts the butting part, and a connecting part which is formed between the elastic arm and the contact part by injection molding. The contact part rotates between a positioning location and an escaping location in the casing through an elastic resetting function which is generated by the elastic arm, so as to quickly replace the butting part on the casing.

A bearing for disposition between a housing and a rotating member, the bearing including: at least one leaf spring element that provides a biasing force in a Y direction; where the bearing has a first stiffness, S.sub.1, in the Y direction and a second stiffness, S.sub.2, in an X direction perpendicular to the Y direction, where S.sub.2≥S.sub.1, and where the bearing includes a metal substrate and a low friction layer overlying at least one surface of the substrate and adapted to contact the rotating member.
