  • Publication number: 20070238323
    Abstract: A terminal for use in an electronic connector for establishing electrical contact with a conductive surface on a first printed circuit board. The terminal includes a base section configured for electrical connection with a second printed circuit board, and a resilient contact beam having a proximal end coupled to the base section and a free distal end. The contact beam is shaped to provide a contact section between the proximal end and the distal end. The contact section is configured for engaging the conductive surface on the first printed circuit board upon insertion of the first printed circuit board into the housing in a first direction. The free distal end of the contact beam extends substantially in the first direction.

  • Publication number: 20070136031
    Abstract: The present invention includes a method of electronically designing an article, including accessing an electronic article design system, selecting an article type to design, and iteratively configuring a group of characteristics by selecting one or more options for each characteristic and/or iteratively modeling the article performance based on a selection of one or more performance parameters for each performance model. In the iterative configuration and modeling step, the electronic article design system automatically presents the characteristics and the performance models based on the article type selected, dynamically updates the article for each step of the iterative configuration and/or modeled performance, and automatically resolves conflicts between iteratively configured characteristics, between iteratively modeled performances, and across iteratively configured characteristics and modeled performances.

  • Patent number: 7168974
    Abstract: Indicator means located in a plug or connector indicates when at least one phase of an AC multi-phase voltage is absent. The indicator means can be any one of a variety of light sources and/or an audible generator. The light source can be, for example, an LED, an illuminating ring visible from any angle around the body of the plug or connector, etc. An opaque barrier can be used to totally or partially block the light from the light source when light from the light indicator may be objectionable such as during a stage lighting application. The indicator means for detecting the absence of at least one phase can be on a printed circuit board connected to receive power from the conductors in the plug or connector.
