摘要： A fusion night vision system has a plurality of hinged joints that allow an operator to adjust the distance between the left eye piece and the right eyepiece while allowing a row of pixels from a display to be maintained viewable through the right eye piece parallel with an imaginary line formed by an optical axis of the left eye piece with an optical axis of the right eye piece.

摘要： Digital video signals are transmitted from a transmitter to a receiver via a digital video interface including shielded twisted pair cables that are surrounded by an over-braid shield. The over-braid shield is connected to a chassis ground at a transmitting end and the receiving end. An interface conveys the received signals to receiver processing circuitry. The interface is connected to an isolated ground, isolating the receiver processing circuitry. The twisted pairs are also connected to the isolated ground, such that a return current is forced back through the twisted pair cable shields rather than the over-braid shield. This reduces electromagnetic emissions and confines transients primarily to the over-braid shield.

摘要： Systems and methods for cancelling interference from a received signal in order to properly detect a signal of interest are disclosed. A combined signal of interest plus interference signal may be received. A copy or sample of the interference signal may be determined. The interference signal and the combined signal of interest plus interference signal may be converted to the optical domain. The interference signal may be optically phase shifted by −180 degrees, which may result in an optically inverted interference signal. The optically inverted interference signal may be variably optically attenuated and/or variably optically time delayed, for example based on a detected output power of an optical subsystem of the interference cancellation system. As a result, interference cancellation of the interference signal from the combined signal of interest plus interference signal may be achieved, resulting in 50 dB or more of cancellation of the interference signal.

摘要： Disclosed herein are methods and systems for configuring and using one or more block ciphering techniques in order to encrypt/decrypt serial data streams while maintaining cryptographic synchronization and attempting to minimize the amount of overhead introduced into the stream. The techniques disclosed herein may be used to encrypt and decrypt serial data streams using a block cipher in a manner that can be substantially transparent to the devices involved in the serial communication session. For example, the serial user data may be left unframed by the encryption device while monitoring for opportunistic times to transmit framed cryptographic synchronization information during periods of relative inactivity in an asynchronous serial data stream. A cryptographic device implementing the techniques described herein may be configured to implement one or more of an encryption device or a decryption device.

摘要： An interference cancellation system (ICS) may be used with a communication system to prevent or minimize interference from one or more sources. The ICS may receive radio RF signals comprised of one or more signals of interest (SOI) and multiple interfering signals. The ICS may use a sample of the interfering signals to cancel the interfering signals from the SOI. The multiple interfering signals may be converted into a single optical signal for cancellation. One or more optical cancellation paths may be used for interference cancellation. Each optical cancellation path may include an optical attenuator and/or an optical delay to achieve phase shifts and/or delays for interference cancellation.

摘要： A display system is provided to surround a user with an out-the window scene. The system includes a screen structure that is a facetted back-projection dome made up of a polygonal polar top facet surrounded by trapezoidal facets angulated downward from it in an upper facet row. A middle row of facets extends angulated downward therefrom, and a lower row of trapezoidal facets extends down from them. Each facet has video projected thereon by a high definition projector, and to maximize resolution and efficiently use the projector output, the vertical height of each facet makes use of the full vertical field of pixels available from the associated projector. The facets are all tangent to a sphere about a design eyepoint of the dome. The projector resolutions and the size, position and material of the facets are such that the imagery visible on the inside of the dome on the facets is at resolution corresponding to a visual acuity of 20/50 or higher, preferably 20/20, and at or near eye-limiting resolution.

摘要： A method and system for identifying a data recorder based upon a unique signature generated for the data recorder. Configuration information is received, the information specifying a plurality of data recording input parameters which are selected to facilitate use of the data recorder in a particular data recording application. A unique signature is generated according for the data recorder, the unique signature including a code which uniquely identifies the data recorder based on a transformation of the configuration information. The unique signature is stored for subsequent access or reference. To differentiate between similar makes and models of data recorders, at least a portion of the unique signature includes a unique core part number that is assigned to only one data recorder by, for example, the manufacturer of the data recorder.
