    Abstract: A flash memory process and device for encrypting and storing data in a non-volatile flash memory associated with a host system. The device includes a flash memory, an encryption engine, a key store, a SRAM to interface with the host system, and associated control circuitry. When powered on, the device first determines if a valid encryption key is held in the key store. If a valid key is held in the store, a program flag is set when encrypted data in the flash memory is ready to be decrypted by the engine and stored in the SRAM for use by the host system, or when data originating from the host system and stored in the SRAM is ready to be encrypted by the engine and programmed into the flash memory. The device can be embedded in any host system wherein data must be encrypted while at rest in a memory.

    Abstract: A method for reducing self-interference in a wireless network, such as a Link 16 network, while maintaining simultaneous multiple access takes advantage of the physical proximity of nodes in a localized subnetwork, such as a fighter-to-fighter subnetwork in a flight wing, by actively reducing the transmit powers used for subnet messages between the nodes. Calibration messages such as Precise Participant Location and Identification (PPLI) messages are exchanged between all of the nodes of the localized subnetwork, from which each node determines the identities, transmit powers, noise levels, and SNRs of all of the other nodes. The node then determines a link margin for other nodes, and sets its transmit power to a “safe” level for the subnetwork according to the lowest link margin.

    Abstract: A system and method of determining a pointing vector using two GPS antennas and a single GPS receiver is disclosed. Two stationary GPS antennas, with a separation preferably less than half of a wavelength (˜100 mm) may use a single receiver to determine the pointing vector of the system. Incorporation of a three axis angular rate measurement allows pointing determination during system rotation. Incorporation of three axis gyroscope system allows pointing determination while in motion. The system provides the ability to sense multipath and jamming. Also the system can potentially eliminate the impact and certainly alert the user that the measurement may not be reliable.
