Disclosed is an elastomeric bladder tool and related systems and methods. In one embodiment, the elastomeric bladder tool comprises an elastomeric inner layer substantially defining an inner cavity of the elastomeric bladder tool, an elastomeric outer layer substantially defining an outer surface of the elastomeric bladder tool, and a permeable middle layer positioned between the elastomeric inner layer and the elastomeric outer layer. The permeable middle layer has greater permeability than both the elastomeric outer layer and the elastomeric inner layer to allow for evacuating of gases that have entered the permeable middle layer.

HEATED COLLAPSIBLE ELASTOMERIC BLADDER TOOL TO FORM AND REPAIR COMPOSITE STRUCTURES
Disclosed is a collapsible heated elastomeric bladder tool (100) for repairing damage to composite structures. The elastomeric bladder tool can be used to repair composite structures in difficult to reach areas, such as under stringers (402) used to stiffen large structures. The elastomeric bladder tool can be inserted into the damaged cavity such as a stringer to support uncured plies (502) during the repair on either surface of the cavity. Integrated heating elements (102) within the elastomeric bladder tool provide heat to cure the plies. The elastomeric bladder tool features a collapsed cross section that facilitates installation and extraction.

A The composite fabrication vent assembly (12) comprises a body member (14) having a first clamping surface (16), a clamping member (18) having a second clamping surface (20), and a carriage member (22) interconnecting the body member and the clamping member such that the first and second clamping surfaces are in opposing relationship. The carriage member is adapted for translating the body member and clamping member relative to one another from an open state to a closed state. When the open end of an inflatable bladder (26) is inserted between the opposed first and second clamping surfaces of the vent assembly, the clamping surfaces form an airtight seal with the open end of the bladder as the clamping surfaces are translated to the closed state. The vent assembly can then control the flow of gas into and out of the inflatable bladder through one or more passageways in the vent assembly.

A composite fabrication vent assembly for connection to an inflatable bladder, the combination of a vent assembly and an inflatable bladder, and a method of mechanically connecting a vent assembly and a bladder. The vent assembly comprises a body member having a first clamping surface, a clamping member having a second clamping surface, and a carriage member interconnecting the body member and the clamping member, with the first and second clamping surfaces in opposing relationship. With the open end of an inflatable bladder inserted between the opposed clamping surfaces, the carriage member is adapted to translate the body member and clamping member toward one another to form an airtight seal with the inflatable bladder. A controlled source of pressurized gas, connected to a gas inlet of the vent assembly, can then inflate and deflate the bladder in a controlled manner through one or more passageways in the vent assembly.
An eyeguard for use on the eye-end of an optical instrument is provided having an instrument-end member adapted for connection to the optical instrument, an eye-end member adapted to interface with the periocular portion of the user's face, a hinge member disposed between the instrument-end and eye-end members having two flexible annular hinges, and a diaphragm comprising a plurality of segments attached to the interior of the hinge member between the annular hinges. The force of the user's eye pressing the eye-end member toward the instrument-end member deforms the annular hinges such that the normally closed diaphragm segments move to an open position, allowing light to pass through the eyeguard.
