Title: Rachael P Marino: Innovator in Touch Technology

Introduction

Rachael P Marino is a prominent inventor based in Londonderry, NH (US). She has made significant contributions to the field of touch technology, holding a total of 3 patents. Her innovative work has paved the way for advancements in user interface design and interaction.

Latest Patents

One of her latest patents is for a multi-touch touch device with multiple drive frequencies and maximum likelihood estimation. This touch-sensitive device includes a touch panel, drive unit, and measurement unit. A touch applied to a given node of the panel changes a capacitive coupling between a given drive and sense electrode of the touch panel. The drive unit delivers first and second drive signals, having different first and second frequencies, to first and second drive electrodes respectively at the same or overlapping times. The measurement unit receives a first response signal from a sense electrode and analyzes the signal using maximum likelihood estimation to determine the coupling capacitance between the first drive electrode and the sense electrode, and between the second drive electrode and the sense electrode. More drive electrodes, including in some cases all the drive electrodes, can be driven with unique drive frequencies, and more sense electrodes, including in some cases all the sense electrodes, can be sensed by the measurement unit.

Another notable patent is for an optical digitizer system with position-unique photoluminescent indicia. This digitizer system includes a substrate having a position-unique photoluminescent indicia pattern. A stylus component receives optical signals indicative of the indicia pattern and determines the position of the stylus relative to the substrate. Methods of disposing indicia on the substrate and styli suitable for sensing photoluminescent indicia are also described.
