Noncontact capacitive sensors work by measuring changes in an electrical property called capacitance. Capacitance describes how two conductive objects with a space between them respond to a voltage difference applied to them. When a voltage is applied to the conductors, an electric field is created between them causing positive and negative charges to collect on each object (Fig. 1).
You are working on a word processing document, and you need access to an item you just copied to the clipboard. You wonder if there is a way to get to the clipboard quickly. The clipboard is a storage area within an operating system for items you copy or cut from a document, website or other computer application. Accessing the clipboard on your computer is not tricky.
