Abstract

An invention for making productive uses of normally undesirable whiskers is provided. Embodiments of the invention include a variety of apparatuses and methods associated with forming and using whiskers as well as forming whisker compounds is disclosed. For example, whisker detection modules can be created which provide a whisker surveillance capability. The whisker detection modules can further be coupled with a whisker response system such as an alarm or insulating material dispersing system. Another aspect of the invention is providing a variety of environments or microenvironments with regard to a whisker forming structure to affect whisker creation such as maximizing whisker formation. Another example includes provision of a variety of embodiments for manufacturing compounds of whiskers of various metal and metal alloys, including structures and methods is provided. Whisker compounds produced using various embodiments of the invention can be used for various applications.

First claim

What is claimed is:

1. A method for detecting and responding to whiskers comprising:
collecting whisker related conditions with respect to a device or structure under whisker formation surveillance;
providing a first structure formed to have at least some physical, chemical, or structural characteristics corresponding to said device or structure under whisker formation surveillance;
generating and controlling whisker formation related interactions with said first structure so as to approximate or match whisker generation related conditions associated with said device or structure under whisker formation surveillance;
detecting whiskers formed on said first structure, wherein said detection comprises a plurality of detection activities comprising a first, second, and third detection activity, wherein said first detection activity comprises shining a light on an area of interest on or near said first structure, said second detection activity comprises sensing a first optical response from said area of interest, and said third sensing activity comprises comparing said first optical response with a stored optical response associated with said region of interest that does not have a whisker formation, wherein one or more said whiskers are detected when there is a mismatch between said first optical response and said stored optical response; and
generating a whisker response needed signal based on detection of said whiskers formed on said first structure.
