  • Laser receiver
    Patent number: 7022963
    Abstract: A laser receiver for detecting the position of incidence of a beam of laser light thereon includes a first photodetector and a second photodetector aligned in series with each other and spaced apart from each other by a gap. If the laser is evenly distributed between the two photodetectors, then the laser position will be set as the correct position and a corresponding signal will be displayed. However, if the first photodetector detects more light than the second photodetector, then a signal will also be displayed to inform the user that more laser is being projected onto the first photodetector. On the other hand, if the second photodetector detects more light than the first photodetector, then a signal will be displayed to inform the user that more laser being projected onto the second photodetector. These signals will assist users to adjust the laser receiver to accurately position the laser.

  • Bubble generating assembly
    Patent number: 7021986
    Abstract: A bubble producing assembly has a housing having an outlet, an air generator positioned on the housing, a bubble producing device positioned over the air generator, a first activator coupled to the air generator, a reservoir associated with the housing for storing a liquid, a pump system coupling the reservoir and the outlet, and a second activator coupled to the pump system for delivering the liquid from the reservoir out of the outlet. Thus, a user can use the first activator to generate air to produce bubbles, and can use the second activator to generate a stream of the liquid that can be aimed at the generated bubbles.

  • Bubble generating assembly
    Patent number: 6988926
    Abstract: A bubble generating assembly has a housing, a container coupled to the housing and retaining bubble solution, a trigger mechanism, a pair of bubble generating rings, a tubing that couples the interior of the container with the rings, and a link assembly that couples the trigger mechanism and the rings in a manner in which actuation of the trigger mechanism causes the rings to be pivoted. Each ring is pivotably coupled to each other in a manner such that the rings can be pivoted between a closed position where the front surfaces of the rings contact each other, and an opened position where the rings are positioned side-by-side in the same plane.
