  • Battery charger using the phase shift by a pair of forward converting circuits
    Patent number: 8179100
    Abstract: A technique for dynamically adjusting an output voltage of forward converter circuits for a battery charging operation is provided. The technique allows for varying voltage at the charging battery by manipulating the duty cycles of two forward converter circuits. Method and systems allow for increasing synchronized duty cycles in a pair of forward converter circuits in response to a changing battery charge state that requires a higher voltage output then changing a phase shift between the duty cycles in response to further increases in output voltage demand. The methods and systems also allow for setting a phase shift between duty cycles in a pair of forward converter circuits based on battery rating and then altering pulse width in response to changing battery charge state.

  • Preconditioned air connector assembly for aircraft
    Patent number: 8146957
    Abstract: In certain embodiments, a PCA connector has a polyethylene body, wherein the polyethylene is durable, corrosion resistant, and exhibits excellent strength over a large range of temperature and moisture conditions. The polyethylene body may be described as a single structure with integral features, such as a bearing portion, a latch housing portion, a latch guide portion, and so forth. Thus, the number of parts is significantly reduced by the one-piece design of the body. In addition, the PCA connector may include a latching mechanism configured to secure the PCA connector to an aircraft. For example, the latching mechanism may include a pair of levers, which engage a pair of latches on opposite sides of the polyethylene body. In some embodiments, the levers may be rotated in opposite directions relative to one another to impart movement of the latches in the same direction, e.g., an axial direction.
