Apparatus and methods to provide a surface having a tunable emissivity are disclosed. An example method includes tuning a characteristic of one or more resonators in a material to change an absorption of radiation by the one or more resonators and to change an amount of destructive interference caused by the material.

Apparatus and methods to provide a surface having a tunable emissivity

A quantum nanomaterial having a bandgap that may be tuned to enable the quantum nanomaterial to detect IR radiation in selected regions including throughout the MWIR region and into the LWIR region is provided. The quantum nanomaterials may include tin telluride (SnTe) nanomaterials and/or lead tin telluride (PbSnTe) nanomaterials. Additionally, a method of manufacturing nanomaterial that is tunable for detecting IR radiation in selected regions, such as throughout the MWIR region and into the LWIR region, is also provided.

Nanomaterial having tunable infrared absorption characteristics and associated method of manufacture

The present disclosure relates to the active initiation of incident energy-dissipating material from a structure surface coating as a counter measure response for the protection of a structure surface. The active initiation is triggered at a predetermined area or areas on a targeted structure surface in response to incident directed energy sensed on a target surface.

Apparatuses, methods and systems for active counter directed energy platform protection

The present disclosure relates to the passive initiation and release of incident energy-dissipating material from locations on an incident energy target surface as a counter measure response for the protection of a platform. The response is activated over a predetermined area or areas on an incident energy target surface in response to an incident directed energy sensed on a target surface.

Apparatuses, methods and systems for passive counter-directed energy platform protection

A transducer assembly is provided. The transducer assembly includes a magnetic portion, a body, a tensile pulse transmitter, and a pulse and current control unit. The magnetic portion is configured to provide a magnetic field. The body is disposed within an opening of the magnetic portion, and has a conductive portion configured to pass electric current near a body surface oriented toward the test surface. The tensile pulse transmitter is disposed within a cavity of the body and configured to transmit a tensile pulse into the test object. The pulse and current control unit is configured to control the tensile pulse transmitted by the tensile pulse transmitter, and to provide a current that passes through the conductive portion of the body and the test object, whereby a force urging the transducer assembly and the test object toward each other is generated responsive to the magnetic field and the current.

Systems and methods for testing internal bonds

A composite bonded structure with integral stress sensing and bond evaluation system incorporates a bonded structure having a first component, a second component and a layer of adhesive bonding the first and second components. The layer of adhesive includes multiple embedded fluorescing particles which emit a first spectral intensity in an unstressed condition and a second spectral intensity in a stressed condition. A bond evaluation apparatus is then employed for measuring spectral intensity.

Bond evaluation using piezochromic fluorescence

Apparatus and methods to provide a surface having a tunable emissivity are disclosed. An example apparatus includes an impedance layer comprising a layer of dielectric material to be attached to an electrically reflective ground plane, and a plurality of resonators arranged within the impedance layer, wherein an emissivity of the apparatus is based on a characteristic of the resonators.

A high intensity light source blocking system for a vehicle operated by a crew member within a cockpit includes an crew member position or eye-position detection system, a transparent dynamic-darkening display covering a window in the crew member cockpit, and a scene imager configured to detect a presence of a high intensity light source and an emanation direction relative to the crew member cockpit. A computing device is connected to the position or eye-position detection system, the transparent dynamic-darkening display and the scene imager, and controls the darkening of a portion of the dynamic-darkening display upon the occurrence of either the high intensity light source having an intensity value equal to or greater than a predetermined threshold, or the crew member position or eye-position being subject to either a direct portion of the high intensity light source or a substantial reflection thereof off a surface within the crew member cockpit.

High intensity light source blocking system and method

A transducer for stimulating an article under test with ultrasonic vibration may include a transducer body having a transmitting face and configured to generate ultrasonic vibration through the transmitting face, and an couplant mounted on the transmitting face, the couplant having a multiplicity of vertically aligned carbon nanotubes extending therefrom in a direction substantially normal to the transmitting face.

A method of manufacturing a composite article may include providing a plurality of fibers. At least a portion of the plurality of fibers may be substantially optically transparent. The method may further include forming the fibers with at least one base surface and a pair of side surfaces oriented in non-perpendicular relation to the base surface. The method may additionally include positioning the fibers in a layer in side-by-side relation to one another such that the side surfaces overlap one another when viewed along a direction normal to a plane of the layer. The method may also include embedding the fibers at least partially in a substantially optically transparent polymeric matrix.
