Abstract: An apparatus and method that intentionally illuminate a number of target devices with RF energy having specific characteristics (e.g., frequency, power, waveform, directionality, duration, etc.) are provided. The target devices, which may comprise a computer system or other electronic circuits, by their fundamental nature as mixed analog and digital devices, act as non-linear mixers and are forced to emit information about the target device behavior, state, and physical characteristics. The apparatus that implements the method receives the forced emissions signals, extracts useful data from noise, and analyzes the data to determine target device characteristics. The target devices may be powered or unpowered. The apparatus and method provided may avoid impacting target device operation.

Abstract: An SDR system and method that intentionally illuminates aircraft systems with RF energy having specific characteristics (e.g., frequency, power, waveform, directionality, duration, etc.) are provided. The aircraft systems act as non-linear mixers and emit non-linear RF energy. A receiver receives the RF energy response and generates an RF energy representation that is correlated to a database of baseline responses. A correlation response between the received RF energy representation and any one of the baseline responses from the database provides an indication of the aircraft system status.

Abstract: An apparatus, method, and computer program product that intentionally illuminate at least one target device with electromagnetic energy having specific characteristics (e.g., frequency, power, waveform, directionality, duration, etc.). The target device, which may be an unpowered data storage device, acts as a non-linear mixer and is forced to emit radiative signals containing information about the target device behavior, state, and physical characteristics. Embodiments receive the forced emissions, extract useful data, and analyze the data to determine target device characteristics (e.g., a target device type, based on a comparison of data from known types). Embodiments control the illumination so the forced emissions radiate from an enclosure without interfering with tactical communications, and so that stored target device data is not affected. Embodiments can locate a hidden target device via the strength and directionality of the forced emissions.

Abstract: An apparatus, method, and computer program product that intentionally illuminate at least one target item with electromagnetic energy having specific characteristics (e.g., frequency, power, waveform, directionality, duration, etc.). The target item, which may be an unpowered data storage device or secure document, acts as a non-linear mixer and is forced to emit radiative signals containing information about the target item's state and physical characteristics. Embodiments receive the forced emissions, extract useful data, and analyze the data to determine target item characteristics (e.g., a target item type, based on a comparison of data from known types). Embodiments control the illumination so the forced emissions radiate from an enclosure without interfering with tactical communications, and so that stored target item data is not affected. Embodiments can locate a hidden target item via the strength and directionality of the forced emissions.

Abstract: A cap and cap extension. The cap is a standard cap and includes an incorporated visor. The cap extension is attached to the rear section of the cap and is designed to cover an individual's neck when the individual is wearing the cap. The cap extension includes a design that provides utility in both preventing sun exposure to an individual's neck, while at the same time, being able to flap about in a light breeze.
