    摘要： A number of methods and systems for overcoming stiction are provided. The systems include electro-mechanical systems capable of exerting a variety of forces upon areas prone to stiction. The systems can be MEMS arrays or other types of devices where stiction related forces occur. The methods include a variety of ways of causing movement in areas prone to stiction forces. Such movement can be vibrational in nature and is sufficient to overcome stiction, allowing a trapped element to be moveed to a desired location.

    摘要： Radius fillers for composite structures, composite structures that include the radius fillers, and systems and methods of forming the radius fillers. The systems and methods may be configured to create a pre-form that may be utilized to form a radius filler and/or create a radius filler from the pre-form. Creating the pre-form may include extending a plurality of lengths of composite tape from a composite tape source and receiving the plurality of lengths of composite tape in a pre-form forming structure, converging and/or otherwise combining the plurality of lengths of composite tape within the pre-form forming structure to produce the pre-form, and/or withdrawing the pre-form from the pre-form forming structure. Creating the radius filler from the pre-form may include receiving the pre-form in a radius filler forming structure and producing the radius filler from the radius filler forming structure.

    摘要： System and method for digitally generating a pulse width modulated (PWM) signal with dither based on a command signal, the signal having a pulse width proportional to the command signal. In the preferred embodiment, the PWM signal with proportional dither energizes a load, such as a variable force solenoid, with a desired electrical current. The system includes a base signal generator for generating a base signal having a pulse width which is based on a command signal representing the desired electrical current. The system also includes a dither signal generator for digitally generating a dither signal having a pulse width proportional to the command signal, and a summer for combining the base signal and the dither signal to obtain the pulse width modulated signal with proportional dither.
