    摘要: A system and method are provided for displaying video surveillance fields of view limitations. The system and method perform video surveillance of a given area and then geo-locate any obstacles within the area, including measuring their overall size and shape. The system and method map the size, location and shape of the objects into a database and then identify where there are video surveillance coverage gaps from each vantage point where video surveillance is being performed on the area. The system and method then determine where there are overlapping locations of blocked video surveillance (i.e., locations that are “invisible” to video surveillance). The system and method create a simulated image of the area from an orientation above the area which indentifies locations within the area that may not be seen by video surveillance from any of the vantage points where video surveillance is being performed.

    摘要: An antenna includes a plurality of loops and a plurality of double pole double throw (DPDT) switches. The plurality of DPDT switches is coupled to the plurality of loops. The DPDT switches are configured to cause a change in direction of current in one or more of the plurality of loops, thereby altering a direction of a magnetic field in one or more of the plurality of loops, such that a device positioned at a plurality of positions in relation to the antenna is electromagnetically coupled to the antenna at the plurality of positions.

    摘要: A system and method for addressing video surveillance fields of view limitations. The system includes a first video camera that located at a first vantage point and a second video camera that is located at a second vantage point. A first lidar is located at the first vantage point and a second lidar is located at the second vantage point. A global positioning system is used to determine the global position of the first and second cameras and the first and second lidars. A processor receives data from the first camera, the second camera, the first lidar, the second lidar and the global positioning system. The processor creates a synthetic video image from any vantage point that is located between the first and second vantage points using the data from the first and second video cameras, the first and second lidars and the global positioning system.

    摘要: An anemometer assembly for sensing and transmitting wind speed and wind direction data. The wind sensor measures relative wind direction and wind speed without the use of moving parts and consumes very little power making it suitable for unattended operation. The main wind sensing member is an elongated vertical member that can be used as radio antenna. The data can be transmitted from a remote location and thus relay data to a central collection repository or network location.
