Patent number: 10678380Abstract: Systems and related methods providing for touch sensors using high sensitivity Lamb waves are disclosed herein. A touch controller may comprise circuitry having operating frequency characteristics, including an operating frequency f and a frequency spread ?f; and circuitry configured to minimize effects of dispersion based upon at least one of selected operating frequency characteristics relative to a frequency dependence of a group velocity of propagating waves and a frequency dependent phase error, wherein the touch controller generates an excitation signal.Type: GrantFiled: November 11, 2016Date of Patent: June 9, 2020Assignee: ELO TOUCH SOLUTIONS, INC.Inventors: David S.

Patent number: 10005265Abstract: Multi-layered paint on a border of a surface acoustic wave touch device may reduce attenuation. The touch substrate has a front surface and a back surface where the front surface has a touch region. Multi-layered paint is formed on the back surface to form a border along the touch substrate. The multi-layered paint includes a mirror layer and a color layer. The surface acoustic waves propagate over at least a portion of the border region such that the surface acoustic waves propagate on the multi-layered paint without excessive wave attenuation.Type: GrantFiled: February 17, 2014Date of Patent: June 26, 2018Assignee: Elo Touch Solutions, Inc.Inventor: David S. Hecht

Patent number: 9507464Abstract: Systems and related methods providing for touch sensors using high sensitivity Lamb waves are disclosed herein. A touch apparatus may include a substrate having a front surface and a back surface, where the touch region is on the front surface. The touch apparatus may be configured to propagate surface acoustic waves on at least a portion of the back surface and high sensitivity lamb waves, such as near-longitudinal-resonance Lamb waves, in at least a portion of the touch region of the substrate. The touch system may further include circuitry configured to determine a location of a touch on the front surface based on received attenuations in the high sensitivity Lamb waves. Some embodiments may provide for bezel-less touch sensor designs and anti-dispersion techniques that enhance touch sensor reliability.Type: GrantFiled: April 29, 2013Date of Patent: November 29, 2016Assignee: Elo Touch Solutions, Inc.Inventors: David S.
