Abstract: A high-speed light detection and ranging (LIDAR) system includes one or more arrays of transmitting laser diodes (TLD) fixed to a mobile platform; multiple such arrays may be arranged around the mobile platform instead of a single array rotating at high speeds. Each TLD of the array transmits, in sequence, a light pulse at a transmit time to illuminate a particular azimuth and elevation. One or more receiving photodiodes (RPD) are fixed to the mobile platform and configured to receive the reflected returns of the transmitted laser pulses. Signal processors allow the LIDAR system to “see” at high resolution by determining distance and directional information and generating point clouds based on the returned pulses.

Abstract: A multilevel security (MLS) network is disclosed. The MLS network includes untrusted nodes (UTN) capable of receiving messages en route from a source node to a destination node, each message having an unencrypted outer header, an encrypted inner header, and a data payload. UTNs route messages toward their destination as directed by the outer header. Global trusted nodes (GTN) decrypt a portion of the inner header to validate source and destination information before routing the message forward. GTNs further modify the outer header to obfuscate source and destination information from the UTNs. Local trusted nodes (LTN) serve as gateway nodes into a local network. LTNs also validate source and destination information to regulate admission to the local network. LTNs include an address manager which decrypts an additional portion of the inner header to read local address data and generates local messages for routing through the local network.

Abstract: A secure onboard maintenance circuit (OMC) includes a primary OMC node with a controller, a secure storage, a trusted CDS interface, and a configurable I/O interface for connecting to at least one system component. The controller is configured to receive maintenance information via the configurable I/O interface and the trusted CDS interface and is further configured to store data associated with the maintenance information in the secure storage. The OMC further includes at least one secondary OMC node with a second controller, a second trusted CDS interface, and a second configurable I/O interface for connecting to at least one other system component. The second controller is configured to receive maintenance information via the second configurable I/O interface and is further configured to transmit the maintenance information to the primary OMC node via the second trusted CDS interface.

Abstract: A platform operates in an environment with other platforms using active sensing. The platform includes an active sensing system configured to provide a point cloud associated with the environment. The point cloud is used to navigate the platform. The active sensing system includes a transmitter configured to provide pulses of electromagnetic energy in a light band or a radar band or sonic energy and a receiver configured to receive returns associated with the pulses striking one or more targets in the environment. The transmitter is configured to impose a code onto the pulses, and the receiver is configured to detect the code to determine when the pulses of light where transmitted or to determine a source of the pulses.

Abstract: A dead reckoning system for dismounted users is disclosed. The system uses a laser emitter to heat fixed points near the user. The points are ranged via LIDAR and imaged via thermal or IR imagers co-aligned with the laser emitter and LIDAR assembly (e.g., as a wearable personal system or a vehicle-based system). The system includes inertial sensors (e.g., accelerometers, gyrometers) to monitor attitude and motion trends of the system. Thermal images incorporating the heated points are captured at new user positions. The dead reckoning system includes a microcontroller for tracking distance and directional changes from one user position to the next by analyzing successive thermal images to determine changes in the position of the fixed heated points relative to the user.

Abstract: A multilevel security fabric with address management units communicatively coupled to ports of a communication fabric and nodes of a multilevel security system are disclosed. The communication fabric facilitates communication between the nodes. An address management unit associated with a particular node extracts address maps contained in data requests associated with the particular node and regulates communication of that node any other nodes within the system across the communication fabric based on whether the extracted address maps are within an allowable address access range specified for the particular node. In the event that an extracted address map fails to fall within the allowable address access range, the address management unit may block the communication with the particular node. Accordingly, the address management unit may enforce multilevel communication across the communication fabric with high assurance.

Abstract: Methods performed by an optoelectronic system are disclosed. A first method may be performed by a pulse data generator configured to acquire time from a clock; determine pulse data representative of a sequence of duration times and/or wavelength ranges as a function of, in part, a wavelength hopping algorithm; and determine and generate an output for controlling an operation of at least one optoelectronic system. A second method may be performed by a sensor controller configured to acquire the pulse data; and generate an output for controlling an operation of an optoelectronic system employed to produce an image viewable to a viewer. A third method may be performed by an image generator configured to acquire the pulse data; acquire digital data from an optoelectronic system; and generate image data representative of an image represented in data acquired from the optoelectronic system as a function of the pulse data.

Abstract: A device for acknowledging warning indicators includes an electro-encephalograph for detecting signals in the midline occipital region of the user's brain, and a display system for displaying flashing indictors having differing flashing frequencies. The electro-encephalograph detects differing signals caused by the differing flashing frequencies whenever the user observes one of the flashing indicators, and the device thereby recognizes that the user has observed the warning indicator.
