摘要:
A touchpad formed from the combination of a flexible and non-conductive material used for a touch-sensitive surface, and a PC board on which is mounted the touchpad circuitry, wherein touchpad sensing electrodes are disposed on the touch-sensitive surface by creating electrical traces formed from conductive ink, the touch-sensitive surface being capable of conforming to various arcuate surfaces, and being capable of sensing through a protective housing such that the touch-sensitive surface is protected, and does not come in direct contact with the pointing object.
摘要:
A stylus that operates utilizing magnetic fields, wherein a permanent magnet is disposed within a passive stylus that is detectable by a plurality of magnetic sensors that remove the magnetic field of the stylus from the earth's relative magnetic field to thereby obtain vectors that are used in a triangulation equation to determine the location of the stylus in two or three dimensions, depending upon the number of magnetic sensors that are used, wherein one set of magnetic sensors can be used as a reference for earth's magnetic field, and wherein each of the magnetic sensors includes a polarizing coil to change direction of sensitivity, a null coil and a flipping coil.
摘要:
A capacitance-sensitive sensor array and associated touchpad sensor circuitry, the sensor array comprised of a flexible substrate having a plurality of printed conductor elements disposed thereon to form the sensor array, the printed conductor elements being coupled to touchpad sensor circuitry that includes data processing capabilities, wherein the sensor array is disposed along an outside surface of a container, wherein the sensor array is capable of conforming to a curved or irregular outside surface of the container, wherein the sensor array detects at least one characteristic of at least one fluid disposed within the container, and wherein the touchpad sensor circuitry processes data received from the sensor array to provide information regarding the at least one fluid.
摘要:
A single-layer touchpad comprised of a relatively clear substrate, a first electrode disposed thereon, and a sense electrode disposed thereon, wherein the first electrode and the sense electrode are comprised of a conductive material, wherein the first electrode in combination with the sense electrode are used to detect the presence of a pointing object in a zone, or the simultaneous presence of multiple pointing objects in multiple zones, and wherein the first electrode and/or the sense electrode are made such that a pattern is visually detectable on the display screen.

摘要:
Touchpad sensor control circuitry that controls the operation of a touch or proximity sensitive touchpad in a first mode, and in a second mode functions as a keyboard controller, wherein the touchpad sensor control circuitry also determines which keys on a keyboard have been actuated by manipulation of keys, wherein pressing a key is detected by the touchpad sensor control circuitry.
