Abstract: An array of curved metal strips is supported over an array of conductors, and a key is supported over each intersection of a metal strip and a conductor. When a user depresses a key, a metal strip is pressed against a conductor to make an electrical connection. As the metal strip is deflected by the key, it snaps or buckles, providing tactile feed back to the user. Each curved metal strip has a tine on one end for coupling the strip to a conductive member on a substrate that supports the strips and the array of condutors.

Abstract: Wrist wearable straps and a case are disclosed, each having an interior cavity for engagedly storing a special tool. One wrist device strap is made of a selected material and defines a pocket for holding the special tool. A second wrist device strap includes at least one special link defining an interior cavity for holding the special tool. These special links also include a removable portion to which is attached a special tool. The removable portion blends with the remainder of the link to give the appearance of a regular link when in place. The wrist device case similarly defines a cavity and includes a removable portion to which is attached a special tool. This removable portion enhances the appearance of the case when in place with the special tool held snugly within the cavity.

Abstract: A keyboard is disclosed comprising a printed circuit board having conductors on only one side. Resilient switching elements are supported by selected ones of the conductors and may be deflected into contact with other selected ones of the conductors by keys supported above the switching elements.
