Abstract: An imaging system for a moving vehicle aggregates pre-existing data with sensor data to provide an image of the surrounding environment in real-time. The pre-existing data are combined with data from one or more 3-D sensors, and 2-D information from a camera, to create a scene model that is rendered for display. The system accepts data from a 3-D sensor, transforms the data into a 3-D data structure, fuses the pre-existing scene data with the 3-D data structure and 2-D image data from a 2-D sensor to create a combined scene model, and renders the combined scene model for display. The system may also weight aspects of data from first and second sensors to select at least one aspect from the first sensor and another aspect from the second sensor; wherein fusing the pre-existing scene data with the sensor data uses the selected aspect from the first sensor and the selected aspect from the second sensor.

Abstract: A scanning antenna system includes a feed line having first and second ends, and a scanning antenna element disposed with respect to the feed line so that, in the transmit mode, a signal input to one of the first and second ends of the feed line is evanescently coupled to the antenna element, whereby the antenna element radiates the signal as a shaped beam through an angular scanning field having a negative angular scanning space and a positive angular scanning space on either side of the stop band near 0°. A switching network, operatively coupled to the feed line, switches the signal input between the first and second ends of the feed line in a controlled sequence, whereby the shaped beam radiated by the antenna element is scanned in the negative scanning space, the stop band, and the positive scanning space. The antenna system performs reciprocally in the receive mode.

Abstract: A system is provided that can introduce data redundancy into wireless communications, and in particular ultra-wideband (UWB) wireless communications to increase the communication range when transmitting data that has low transmission rates. Multipath degradation, introduced by the extended communications range, can be mitigated by frequency hopping between the orthogonal frequency-division multiplexed symbols of the ultra-wideband waveform. Frequency hopping can place adjacent symbols in different frequency channels for filtering. Data redundancy can be expanded in the time domain and/or the frequency domain, resulting in extended range.

First and second dielectric strips are flush-mounted on the inner surfaces of the first and second conductive metal bases, respectively, the first dielectric strip extending longitudinally along the inner surface of the first base, and the second dielectric strip extending longitudinally along the inner surface of the second base, opposite the first dielectric strip.

Abstract: A medical data point of care device is configured to collect, access, store, and distribute patient medical data. The device is particularly suited for use in a mobile environment and may be particularly useful in an urgent care mobile environment, such as a battlefield or disaster area. In such environments, data transmission services may be intermittent and the bandwidth of such services may be low. The device is configured to adjust the flow of data transmission from a point of care location to a remote location so as to maximize or otherwise increase the likelihood of successful transmission of the data. The device is further configured to collect data from both a care provider and a medical device.

Abstract: An electronically-controlled steerable beam antenna with suppressed parasitic scattering includes a feed line defining an axis x; and first and second arrays of electronically-controlled switchable scatters distributed along the axis x, each of the scatterers in the first and second arrays being switchable between a high state and a low state to scatter an electromagnetic wave propagating through the transmission line so as to form a steerable antenna beam. Each of the scatters of the second array is configured to be 180°-phase-shifted relative to a corresponding scatter of the first array. The switchable scatterers of the first and second arrays are configured into high states and low states relative to each other so as to suppress parasitic scattering of the electromagnetic wave without suppressing the steerable antenna beam.

Abstract: A waveguide includes a dielectric substrate having first and second opposed surfaces defining a longitudinal wave propagation path therebetween; and a conductive grid on the first surface of the substrate and comprising a plurality of substantially parallel metal strips, each defining an axis. The grid renders the first surface of the substrate opaque to a longitudinal electromagnetic wave propagating along the longitudinal wave propagation path and polarized in a direction substantially parallel to the axes of the strips. The grid allows the first surface of the substrate to be transparent to a transverse electromagnetic wave having a transverse propagation path that intersects the first and second surfaces of the substrate and having a polarization in a direction substantially normal to the plurality of metal strips. A diffraction grating on the second surface allows the waveguide to function as an antenna element that may be employed in a beam-steering antenna system.
