Abstract

This document describes an interactive object with multiple electronics modules. An interactive object (e.g., a garment) includes a plurality of conductive threads woven into the interactive object, and an internal electronics module coupled to the array of conductive thread. The internal electronics module includes a first subset of electronic components, such as sensing circuitry configured to detect touch-input to the grid of conductive thread. An external electronics module that includes a second subset of electronic components (e.g., a microprocessor, power source, or network interface) is removably coupled to the interactive object via a communication interface. The communication interface enables communication between the internal electronics module and the external electronics module when the external electronics module is coupled to the interactive object.

First claim

What is claimed is:

a plurality of conductive threads, the conductive threads having a first end and a second and opposite end, the conductive threads being substantially linear and parallel from the first end to the second end, the conductive threads being integrated into the interactive object;
an internal electronics module coupled to the plurality of conductive threads, the internal electronics module comprising a flexible substrate having a width and a length and a plurality of electrical contact pads positioned sequentially along the width of the flexible substrate, each electrical contact pad being connected to a respective conductive thread; and
a controller in electrical communication with each of the electrical contact pads, the controller being configured to detect a touch-input when user pressure is applied to the conductive threads, the controller also being configured to communicate touch-input data to a computing device.

2. An interactive object as defined in claim 1 , wherein the flexible substrate and the plurality of electrical contact pads comprise a flexible printed circuit board.

3. An interactive object as defined in claim 1 , wherein the first end of each conductive thread is connected to a respective electrical contact pad, the first end of each conductive thread including a free end section not integrated into the interactive object, each end section including slack between the electrical contact pad and a location where the end section enters the interactive object.

4. An interactive object as defined in claim 3 , wherein the slack of each conductive thread has an S-like configuration between the electrical contact pad and the location where the end section enters the interactive object.

5. An interactive object as defined in claim 3 , wherein the slack has a distance that is at least 50% greater than the linear distance between a location on the electrical contact pad where the conductive thread is connected and the location where the end section of the conductive thread enters the interactive object.

6. An interactive object as defined in claim 3 , wherein the slack has a distance that is at least 80% greater than the linear distance between a location on the electrical contact pad where the conductive thread is connected and the location where the end section of the conductive thread enters the interactive object.

7. An interactive object as defined in claim 1 , wherein the connection between each conductive thread and a respective electrical contact pad is coated with a first coating comprising a rigid adhesive and wherein the rigid adhesive is encapsulated by a polymer coating.

8. An interactive object as defined in claim 7 , wherein the conductive thread is soldered to the electrical contact pad.

9. An interactive object as defined in claim 2 , wherein the printed circuit board includes a first portion where the electrical contact pads are located and a second portion comprising a microprocessor and wherein the second portion is overmolded with a rigid polymer composition.

10. An interactive object as defined in claim 1 , wherein the second end of each conductive thread includes a free end section that is not integrated into the interactive object.

11. An interactive object as defined in claim 10 , wherein the free end sections of the second end of each conductive thread is laminated to the interactive object by a polymer film.

12. An interactive object as defined in claim 1 , wherein the internal electronics module further includes a ramp portion that extends from a surface of the interactive object to the plurality of electrical contact pads, the conductive threads being positioned on the ramp portion when extending from the interactive object to the electrical contact pads.
