Abstract: A multi layer interconnecting substrate has at least two spaced apart metal layers with a conductive pad on each one of the metal layers. Two different types of insulating layers are placed between the metal layers. The placement is such that one of the two different types of insulating layers is placed between the conductive pads and the other type of insulating layer is placed between the two spaced apart metal layers.

Abstract: A self configuring multiple element portable electronic device (100) and method is provided. The device comprises at least a first electronic element (104) and a second electronic element (106) and a joint (112) connecting the first electronic element and the second electronic element, with the joint allowing movement in more than one plane of the first electronic element in relation to the second electronic element, wherein the self configuring multiple element portable electronic device is capable of self configuring an operational mode based on a relative position of the first electronic element with respect to the second electronic element. The method comprises the steps of detecting a relative position of the first electronic element relative to the second electronic element, and selecting an operational mode of the device based on the relative position.

Abstract: A pointer control for movement of a pointer or cursor across a computer display includes a movement sensor mounted on a headband to translate motions of a user's head into movements of the pointer. The movement sensor may be an inertia sensor. Wired and wireless configurations are provided. Selection switches for selection of the graphical elements indicated by the pointer are provided in an auxiliary keyboard module for mounting on the keyboard or alternately as foot operated switches. Add-on modules convert the head movement sensor to a hand-moved sensor. A laser pointer may be provided.
