  • Publication number: 20120255650
    Abstract: A guard for a log splitter apparatus is disclosed herein. In various aspects, the guard includes a support member adapted to be secured to a rail of a log splitter apparatus, and a panel hingedly secured to the support member. The panel may be lockably positionable at least between a collapsed position and an extended position. The panel is adapted to capture at least portions of a log, in various aspects. In various aspects, a plurality of support members are located about the panel to secure the panel to the rail of the log splitter apparatus. The support members may be located such that the support members and the panel avoid interference with mechanisms of the log splitter apparatus with the guard secured to the rail. This Abstract is presented to meet requirements of 37 C.F.R. §1.72(b) only. This Abstract is not intended to identify key elements of the apparatus and methods disclosed herein or to delineate the scope thereof.

  • Patent number: 7300354
    Abstract: An inflatable structure includes a first inflatable section having an interior open to an airflow from a blower, and a second inflatable section attached to the first inflatable section and having an interior that is substantially closed from the airflow such that if the airflow is stopped the second inflatable section will not deflate as fast as the first inflatable section and will support the first inflatable section.

  • Publication number: 20060204938
    Abstract: The system assesses problem behaviors and identifies those behaviors to be targeted through the use of an interview process that generates a behavior rating report. Through a parenting style interview, the system provides parents with issues that may influence their parenting skills, and helps the parents discover the strengths and weaknesses of their particular parenting style. A unique plan for each child is then developed to minimize problem behavior by changing the parents' response to the behaviors. This teaches the child that good decisions lead to positive consequences and higher self-esteem. A behavior chart is created and used to track the child's problem behavior. After a period of time, one week, the parent returns to develop a consequence system to improve behavior of the child. The child's baseline behavior is calculated, which will be used to measure progress. Specific consequences are determined that will be used to motivate the child to change his or her behavior.

  • Publication number: 20050048335
    Abstract: An apparatus and accompanying method for controlling a fuel cell power system having a fuel cell stack with a connected energy storage medium. A voltage monitoring circuit is connected to the individual fuel cells forming a fuel cell stack. A regulating circuit receives signals from the voltage monitoring circuit and outputs a control signal to a DC-DC converter connected between the fuel cell stack and an output bus and energy storage medium. The regulating circuit controls the DC-DC converter voltage output to a maximum power that the fuel cell stack can provide.
