A display film includes a transparent polymeric substrate layer having a 0.2% offset yield stress greater than 110 MPa and a transparent aliphatic cross-linked polyurethane layer having a thickness of 100 micrometers or less disposed on the transparent polymeric substrate layer. The transparent aliphatic cross-linked polyurethane layer has a glass transition temperature in a range from 11 to 27 degrees Celsius and a Tan Delta peak value in a range from 0.5 to 2.5. The display film has a haze value of 2% or less.

Thin protective display film

Various embodiments of an accessory mounting device are disclosed. The device can be adapted to engage an elongated rail. The device can include a body having top, bottom, and first and second side surfaces. Each of the side surfaces can include a rail engagement portion adjacent the bottom surface of the body and an accessory engagement portion adjacent the top surface. The device can also include a locking mechanism including a lever connected to the body at a pivot, and a tab extending from the lever in a direction away from the bottom surface. In one or more embodiments, the locking mechanism can include first and second levers each connected to the body at a pivot. The lever can rotate about a pivot axis in a direction toward the top surface of the body when the locking mechanism is manipulated from a locked position to an unlocked position.

Accessory mounting device and system using same

A display film includes a transparent cross-linked polyurethane layer. The transparent cross-linked polyurethane layer having a glass transition temperature of 10 degrees Celsius or less and a Tan Delta peak value of 0.5 or greater.

Low Tg polyurethane protective display film

A flexible OLED display device that includes an upper module having a cover window film, a lower module, and a display module between the upper and lower modules. The display module includes an OLED and an OLED substrate. The stiffnesses of components in the display device are controlled to satisfy a particular relationship such that the bending stiffnesses of the upper and lower modules are tuned in order to position the neutral bending plane below the display module, which places the display into a state of compressive strain as opposed to zero strain. This design is suitable for a bifold flexible display in which the upper module can be folded to face itself.

Foldable OLED device with compatible flexural stiffness of layers

A compound for protection of an object from a blast or shock wave. The compound include a matrix material and at least a first and second sets of inclusions in the matrix material that differ in size, quantity, shape and/or composition in a direction through the impact-absorbing material, the combination of which contributes to the ability of the material to exhibit at least one property that changes as the inclusions are deformed in response to a blast or shock wave.

Method of making a blast or shock wave mitigating material

A display film includes a transparent polymeric substrate layer and a transparent aliphatic cross-linked polyurethane layer disposed on the transparent polymeric substrate layer. The transparent aliphatic cross-linked polyurethane layer has a glass transition temperature in a range from 11 to 27 degrees Celsius and a Tan Delta peak value in a range from 0.5 to 2.5. The display film has a haze value of 1% or less.

Protective display film

A double-shell helmet is disclosed. The double-shell helmet includes an outer shell, an impact absorbing material layer affixed to the outer shell on a first side of the impact absorbing material layer, an inner shell affixed to the impact absorbing material layer on a second side of the impact absorbing material layer opposite the first side of the impact absorbing material layer, and a foam layer affixed to the inner shell.

Dynamic load-absorbing materials and articles

Dynamic load-absorbing materials suitable for use as cushion-type and armor-type materials, for example, of types that can be incorporated into protective gear, equipment, armor, vehicles, and various other structures, or used for the isolation and dissipation of vibratory loads, such as vibration isolators used to support avionic equipment. The impact-absorbing materials include a matrix material () and at least first and second sets of inclusions (which can be either included material or voids) () in the matrix material () that define a hierarchy of inclusions () in the matrix material (). The inclusions () differ in size, quantity, shape and/or composition in a direction through the impact-absorbing material, the combination of which contributes to the ability of the material to exhibit at least one property that changes as the inclusions () are deformed under load.
