One aspect of the disclosure is a plaster board having a first edge and an opposed second edge, and a third edge and an opposed fourth edge. The plaster board includes a first layer of hardened plaster material including a first surface and an opposed second surface, and a second layer of hardened plaster material including a first surface and an opposed second surface. The second layer of hardened plaster material is stacked against the first layer such that their first surfaces face one another. The first layer and the second layer together define the first, second, third, and fourth edges of the plaster board. The plaster board also includes a viscoelastic polymer disposed between the first surfaces of the first and second layers of hardened plaster material. The viscoelastic polymer does not extend substantially to the first, second, third, and fourth edges of the plaster board.

Methods, systems, and devices are described for isolating a crystal oscillator assembly from shock and/or vibration inputs. A system may include one or more vibration isolators coupled between the crystal oscillator assembly and the base structure, and each of the vibration isolators may include a spring material layer and a damping material layer. The spring material layer may provide a spring force between the crystal oscillator assembly and the base structure. The damping material layer may be adhered to at least one side of the spring material layer, and may provide a damping force between the crystal oscillator assembly and the base structure. Some vibration isolators may further include a constraint layer adhered to the damping material layer, such that the damping material layer is coupled between the constraint layer and the spring material layer.

The known dog boots and coats lack in the area of “easy to put on” and “stays on”. The present invention relates to a boot, including: a fabric material; a silicone gel material for covering the inner surface of the fabric material, the silicone gel material being connected to the fabric material; wherein the boot is configured to be reversible so as to cover and conform to a paw and lower leg of the domestic animal that comes in contact with the silicone gel material while the boot is put on; and wherein the silicone material and fabric material are configured to flexibly and removably secure, through the flexibility of the fabric and silicone materials, the boot to the paw and lower leg of the domestic animal; and wherein the silicone gel material provides shock-absorbing protection to the paw. The coat includes a portion with three layer fabric/silicone/fabric.

Provided is a window including a glass substrate, an impact absorbing layer disposed on the glass substrate and having a first storage modulus, and at least one coating layer disposed on at least one of top and bottom surfaces of the impact absorbing layer, respectively, and having a second storage modulus that is greater than the first storage modulus, wherein a ratio between a first thickness of the impact absorbing layer and a second thickness of at least one of the at least one coating layer is about 1:0.0002 to about 1:0.05.

What is presented is a unit cell comprising a cellular geometry that comprises cell walls and cell edges arranged into a combination of a cubic cell geometry and a tetrahedral cell geometry arranged to have a coincident central vertex. The cubic cell geometry comprises three orthogonal cell faces that intersect at its central vertex. The tetrahedral cell geometry comprises an arrangement of eight tetrahedral cells that share its central vertex such that each tetrahedral cell shares three coincident edges with three other tetrahedral cells in a cubically symmetric arrangement. The tetrahedral cell geometry is combined with the cubic cell geometry such that all vertices of the tetrahedral cell geometry are coincident with the vertices of the cubic cell geometry.

The present invention relates to multi-layered hybrid and functional graded aluminum foam obtained from waste aluminum beverage cans, and to the production method thereof. This multi-layered aluminum composite foam can be used in bullet-proof armors in many fields such as aviation, defense industry, automotive and rail systems, in decreasing the impact effect in fast trains and automobiles, in vibration damping, in absorbing energy during impact and shock, in electromagnetic shields, as air buffer panel in carrying heavy vehicles such as tanks, in providing sound insulation on motorways and for flame retardant purposes.

An impact resistant vehicle cover assembly includes a first sheet that is positionable over a vehicle. The first sheet is comprised of a synthetic textile such that the first sheet is inhibited from abrading the vehicle. A second sheet is positioned on the first sheet and the second sheet is comprised of a resiliently compressible material to protect the vehicle from impact damage. A plurality of domes is each coupled to the second sheet and each of the domes is comprised of a resiliently compressible material to protect the vehicle from impact damage. A third sheet is positioned over the domes and the third sheet is comprised of a resiliently compressible material to resist being damaged by projectiles.
