Abstract:
The production of bullet resistant glazing tends to be labor intense as compared to typical non-BRG glazing. Many steps are required to assemble and laminate the multiple layers required and production volumes tend to be low as well. By producing large laminates and subsequently cutting small to medium sized parts from the larger sheet and through the use of a cold edge sealing method, the labor is greatly reduced and throughput is greatly increased.
Abstract:
A system includes a first camera configured to capture first image data of a first field of view in a first direction. The system also includes a second camera configured to capture second image data of a second field of view in a second direction opposite the first direction. A first display faces the first direction and is configured to display a portion of the second image data. The first display is coupled to the second camera via a first communication line. A second display facing the second direction is configured to display a portion of the first image data, the second display coupled to the first camera via a second communication line.
Abstract:
A laminate structure has first and second polymer layers with a glass layer between the first and second polymer layers. The glass layer is fused to the first and second polymer layers. The glass layer is encapsulated by the first and second polymer layers, and the glass layer is in compression.
Abstract:
The present invention provides a lightweight blast-mitigating polycarbonate laminate system comprising at least one polycarbonate sheet, a portion of which is laminated to a glass layer having a thickness between 0.25 times and less than 1 times the thickness of the polycarbonate sheet. The laminate system may further include fasteners to attach the system to a building, positioned to prevent the laminate system from breaking or detaching in case of a blast event.

Abstract:
A rotary wing aircraft is provided including an airframe having a nose section located at a forward end. A window assembly is coupled to the nose section. The window assembly includes a frame and a transparent armored window. The frame has a large opening and a lip extends from a portion of the frame adjacent the large opening. The transparent armored window is formed from a plurality of layers and has a shape generally complementary to the large opening. When the transparent armored window is received within the large opening of the frame, a portion of the transparent armored window is attached to a portion of the lip.
Abstract:
Attacks from improvised explosive devices (IEDs) are one of the major causes of soldiers being killed in action (KIA) and wounded in action (WIA). Such improvised explosive devices can cause considerable damage, disability and death from a device as small as a cellular telephone, to several thousand pounds of explosive material, and linked military artillery munitions, capable of cutting armored vehicles in half, to completely destroying the vehicle and killing all occupants within. A wide range of protective wear/gear or garments, have been designed to shield against a percentage of explosive blast effects of smaller less lethal improvised explosive devices and munitions, in an effort to reduce human casualties associated with explosive ordnance disposal. However, such protective wear/gear or garments have failed to keep pace with the evolution of improvised explosive devices, their destructive capabilities, and the technical sophistication of those responsible for their creation and fabrication. Improvised explosive devices (IED), and Vehicle borne improvised explosive devices (VBIED), are increasingly being used to the determent of the explosive ordinance personnel sent out to respond and either disarm or destroy the explosive devices. Additionally, with the rise in relay or remote control detonation, the EOD technicians face the threats of pre- detonation approaching the device(s), or subsequent detonation to the EOD technician departing the disarmed primary threat only to have a secondary IED threat detonated fatally injuring or killing him. Approach and departure from purposely designed, manufactured, disguised and concealed IED threats and the methods of their deployment are increasing in their complication of designs, performance capabilities and modes of utilization to the extreme detriment of soldiers, law enforcement and EOD technician personnel. These increasingly common events translate into a greater need for explosive ordnance disposal (EOD) technicians and a greater risk incurred by the EOD technicians employed by the military and law enforcement agencies. In the past, the use of bomb disposal protective equipment has meant an overwhelming weight burden, restrictive internal movement space, minimum fragmentation velocity resistance, absence of ballistic resistant capabilities, the loss of dexterity and eye- hand coordination to the detriment of the render-safe mission though reduced flexibility and overheating. The advent of newer materials with greater protective capabilities, flexibility, cooler to operate within, increased visibility through the helmet, and lighter weight, coupled with increased levels of protection, represents a significant improvement for EOD technician personnel, and explosive blast detonation defeat protection.
Abstract:
A structurally reinforced optically transparent panel that may be utilized as a bulletproof window or shield. The panel includes a plurality of angled reinforcement members having a reflective front and back surfaces. Optical lenses are disposed between the reinforcement members directing a light ray in a predetermined direction. The geometry and spacing of the reinforcement members is such that the light rays enter and exit the bulletproof panel at substantially the same angle allowing an observer to view optical images of objects behind the bulletproof panel, thus creating optical transparency. The reinforcement members are of a high strength material capable of being impenetrable by a projectile fired from a ballistic weapon or an explosion debris.

This invention relates to a process for the preparation of an antiballistic article, the method comprising: a) Providing a transparent uniaxially stretched polymeric film with at least one layer I comprising a semi-crystalline thermoplastic polymer A and at least one layer II comprising an amorphous or semi-crystalline thermoplastic polymer B, of which polymer B has a glass transition temperature less than the melting temperature of polymer A if polymer B is amorphous or of which polymer B has a melting temperature less than the melting temperature of polymer A if polymer B is semi-crystalline; b) Stacking at least two of the uniaxially stretched polymeric films of a) at an angle a of between 45° and 135°, such that the films are in contact with each subsequent film through at least one layer II, to form an assembly; c) Compressing the thus formed assembly at a temperature above the glass transition temperature of polymer B if polymer B is amorphous, or above the melting temperature of polymer B if polymer B is semi-crystalline, and below the melting temperature of polymer A, to obtain an haze of at most 50% and having an energy absorption for 17 grain FSP according to the STANAG 2920 standard of at least 12 J/(kg/m 2 ). The invention also relates to antiballistic articles.

The present invention discloses a curved bullet-proof composite having glass, glass- ceramic or flexible ceramic in the strike-face layer in order to be mechanically curved during a low heat (temperature) and pressure lamination process. The composites can be made of one or more gravity and heat-curved glass, glass-ceramic or ceramic layers in one or more intermediate layers.
