  • Direction finding and geolocation of wireless devices
    Patent number: 7978139
    Abstract: Techniques are disclosed that allow for the detection, identification, direction finding, and geolocation of wireless emitters in a given multipath environment. For example, the techniques can be used to detect and identify a line of bearing (LOB) to an IEEE 802.11 emitter in a building or in an open field or along a roadside. Multiple LOBs computed from different geographic locations can be used to geolocate the target emitter. The techniques can be embodied, for instance, in a vehicle-based device that can survey the target environment, detect an IEEE 802.11 emitter and identify it by MAC address, and then determine various LOBs to that emitter to geolocate the emitter. In some cases, a sample array of response data from the target emitter is correlated to a plurality of calibrated arrays having known azimuths to determine the LOB to the target emitter.

    Patent number: 7974505
    Abstract: A method for fabricating selectively coupled optical waveguides on a substrate is disclosed. Initially, a first layer of waveguide material is deposited on a substrate. The first layer of waveguide material is then etched to form multiple level one waveguides and fill shapes. A dielectric layer is deposited on top of the level one waveguides and fill shapes. The surface profile of the dielectric layer deposition tracks the pattern density of the fill shapes. After the surface of the dielectric layer has been polished, a second layer of waveguide material is deposited on the substrate. At least one optically coupled waveguide structure, which is formed by a first level one waveguide and a first level two waveguide, is located adjacent to at least one non-optically coupled waveguide structure, which is formed by a second level one waveguide and a second level two waveguide.

    Patent number: 7969216
    Abstract: Embodiments of a method and system for both open-loop and closed-loop timing synchronization are provided in which a master clock signal, and a plurality of signals that define greater periods of time, are distributed to a plurality of host devices. A frame-sync signal is used to define a “frame” consisting of a predetermined number of clock periods, and a reset signal is used to define a larger period consisting of a predetermined number of frames. Due to a variety of system parameters, the innate delay time associated with each respective timing distribution path may differ. The system is operable to adjust the timing signals propagated to the plurality of host devices along each respective timing distribution path to compensate for these differences so that each host device remains synchronized with all other host devices.
