Overlay applicator tray and method of using the same
An overlay applicator tray including a cradle including a device slot. The device slot is configured to securely hold an electronic device in the cradle. The overlay applicator tray also can include an overlay applicator. The overlay applicator can include an overlay layer and an adhesive release liner. The overlay layer can include a top side and a bottom side. The bottom side is configured to be adhered to a screen of the electronic device. The adhesive release liner is removably attached to the bottom side of the overlay layer. The overlay applicator tray additionally can include an alignment piece coupling the cradle to the overlay applicator. The alignment piece aligns the overlay layer of the overlay applicator with the screen as the overlay layer is applied to the screen when the electronic device is securely held in the device slot.

Plaster boards having internal layers and methods for making them
Disclosed herein are plaster boards that include first and second layers of hardened plaster material, a liner attached to the first layer of hardened plaster material, and a first material (e.g., a polymer material such as a viscoelastic polymer) adhered between the liner and the second layer of hardened plaster material. The liner includes one or more structurally weakened regions each extending substantially from a first edge to a second opposing edge of the plaster board. The structurally weakened regions of the liner may facilitate creation of a fissure that propagates substantially within a plane within the plaster board. Methods for making the plaster boards may involve drying wet plaster material while it is in contact with a liner having structurally weakened regions, processing a liner to form its structurally weakened regions while in contact with wet plaster material, or processing a liner to form its structurally weakened regions while in contact with hardened plaster material.

BLISTER ASSEMBLY
A blister assembly comprises at least one collapsible blister adapted, as it is collapsed, to eject a liquid contained therein. The blister assembly comprises a first layer (130) having at least one blister chamber (150) and a second layer (131) sealed to the first layer at least around a periphery of the at least one blister chamber such that a liquid is contained between the first layer and the second layer. The seal between the first and second layers comprises a first planar portion having a first peel strength and a second planar portion having a second peel strength, wherein the first peel strength is greater than the second peel strength, such that when pressure is applied to the blister, the second portion of the seal breaks to release the liquid contained within the chamber into the liquid inlet. The blister assembly further comprises at least one discontinuity (142) formed in the first and second layers in the region of the first portion of the seal, such that a shear force is required to delaminate the first and second layers in that region.
