    摘要： A device for preparing and reseeding small bare spots in a lawn is in the form of a telescoping tubular member having upper and lower, relatively slidable tubes, with the storage hopper for the grass seeds being provided in the upper tube, and wherein a valve means is provided at the connection between the upper and lower tubes for controlling the flow of seeds from the storage hopper through the lower tube to the bare spot on the ground. The valve means preferably comprises a caged ball secured within the upper tube, and an actuating means secured to the lower tube. Spring biasing means are provided to maintain the tubular member in its extended position, with the valve means being closed. The lower end of the lower tube is formed with teeth for initially scoring the bare spot. Next, the tubular member is compressed along its axial length, thereby momentarily actuating the ball valve to enable a measured amount of grass seed to fall through the tubular member for deposit on the ground. In its fully compressed position, the ball closes off the hopper so as to prevent additional seed from falling through the seeder, and when the tubular member is released, the spring means telescopes the tubes so as to again close off the ball valve. A screen may be provided in the lower tube for aiding in the uniform distribution of the seeds.

    摘要： A sensor array system for detecting the position of an object or energy source. The system includes a plurality of sensors, each sensor having a limited field of view and being capable of detecting an object or energy source that is positioned within its field of view. The fields of view of at least some of the sensors overlap the fields of view of other sensors, and the overlapping fields of view define unique spatial regions. A data acquisition system is operatively connected to the plurality of sensors and is used to determine which sensors simultaneously detect an object or energy source, thereby determining the unique spatial region in which the object or energy source is located.
