  • Patent number: 8201972
    Abstract: A decorative tree has a trunk, a plurality of double limbs and individual limbs connected to the trunk, and controlling electronics. Each double limb includes two individual limbs joined at a branch joint. Each individual limb has a plurality of flexible lamp stems and a molded branch formed around a structural rod. The lamp stem has two insulated wires, has a stiffening rod wrapped in a smooth sheath, and terminates in a molded lamp holder that supports an LED. Each lateral lamp stem connects to the molded branch at a molded branch fork and the tip lamp stem connects to an end of the stiffening rod. The controlling electronics provide an operating signal to the LED, which preferably causes the LED to sequentially emit more than one color in a repeated sequence.

  • Patent number: 7796046
    Abstract: A rodent repeller having an elongated body, an end cap, an apex, a power supply, a buzzer, and a buzzer transformer. Connection of the power supply to the audible signal generator via the audible signal generator transformer produces a signal in the form of a chatter sound that mimics a frightened rodent to discourage rodents from remaining in a vicinity of the rodent repeller. The rodent repeller can further utilize solar power.

  • Patent number: 7740177
    Abstract: A solar light stick for use as a lawn or garden novelty. The solar light stick has a support member, a solar panel, a rechargeable battery, an LED, and a wand. The wand contains a light transmissive material that may be transparent or translucent. The solar panel charges the rechargeable battery which, in turn, provides power to the LED. The LED is positioned to provide light to the interior of the wand. As such, the LED may be located within a recess in the wand. Voids, such as interior bubbles, suspended objects, or surface irregularities may help to disperse light from the LED in a direction external to the wand.

  • Patent number: 7598879
    Abstract: A rodent repeller having an elongated body, an end cap, an apex, a power supply, a buzzer, and a buzzer transformer. Connection of the power supply to the audible signal generator via the audible signal generator transformer produces a signal in the form of a chatter sound that mimics a frightened rodent to discourage rodents from remaining in a vicinity of the rodent repeller. The audible signal can be amplified with perforations in the apex, a tympanic resonator in the elongated body, or both. The rodent repeller can further utilize solar power.
