  • Patent number: 8011327
    Abstract: A variable voltage electronic pet training apparatus. The variable voltage electronic pet training apparatus controls the intensity of the stimulation by the controlling the voltage level present at the primary side of the transformer while maintaining a fixed signal to the correction pulse switch. A trigger signal contains information about the desired stimulus intensity level. A controller interprets the trigger signal and produces a voltage control signal associated with the desired energy level. Application of the voltage control signal to a power converter keeps the voltage level applied to an energy storage capacitor sufficient to produce the desired stimulation intensity.

  • Patent number: 7996983
    Abstract: An animal training apparatus including an electrical conductor embedded within a flexible member, and a housing having a through-opening for receiving the electrical conductor therethrough. The flexible member is molded around the electrical conductor and the antenna, while the electrical conductor is positioned such that it extends into the housing through the through-opening. As a result of the molding process, the flexible member shields the housing through-opening, discouraging substances such as water from accessing the interior of the housing via the through-opening.
