  • Publication number: 20110096546
    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: 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.

  • Publication number: 20090208353
    Abstract: A motorized fan with a whimsical figure appearance that has an electric fan and a body member, and it may also have appendages and a support base. The body member is connected to the electric fan such that the electric fan is generally located within the body member. The appendage may represent the arm, leg, tail, neck, wing, head, tongue, quill, antenna, or other body part that is connected to the body of the whimsical figure. There may be a plurality of appendages. An appendage may further contain additional embellishments to represent other features of the whimsical figure's body, such as the brush at the end of a tail, feet, hooves, the figure's head, fins, flippers, hands, ears, horns, feathers, or whiskers. Preferably, the whimsical figure is the characterization of an animal.

  • Publication number: 20080166504
    Abstract: An apparatus and a method involving a novelty item apparatus, having a flat surface for facilitating laying the apparatus on a horizontal surface, mounting the apparatus to a vertical surface, and mounting the apparatus into a permeable material using an elongated member. The apparatus further involves flexibly connected moveable parts for providing environmental whimsy. The apparatus generally involves a body and at least one appendage being coupled to the body using a structure for flexibly connecting the at least one appendage to the body. The apparatus has sculptural features and mechanically responds to wind or other incident forces in a displaceably suspended manner, i.e., springing reaction to an incident force.

  • Publication number: 20080157982
    Abstract: A rodent repeller having an elongated body, an end cap, an apex, a power supply, a buzzer, an LED, an LED transformer, and a buzzer transformer. Connection of the power supply to the buzzer via the buzzer transformer produces a signal to discourage rodents from remaining in a vicinity of the repeller stake, and connection of the power supply to the LED via the LED transformer produces a visual indicator that the repeller stake is operable. The LED transformer receives a voltage from the power supply, and the voltage varies in amount from a high voltage to a low voltage. The LED transformer controls the amount of power to the LED such that the LED has a high brightness when the high voltage is received by the LED transformer and the LED has a low brightness when the low voltage is received by the LED transformer.
