CAPACITIVE SENSING DEVICE
First Claim
1. A capacitive sensing device comprising:
- an enclosure including a top layer having an external surface and an internal surface opposite the external surface;
a substrate including a first portion affixed to the internal surface, a second portion spatially separate from the first portion and configured for communication with a processor, and a bendable portion between the first portion and the second portion; and
an array of capacitive sensors disposed on the first portion of the flexible substrate, the array of capacitive sensors configured to sense objects proximate the external surface.

Abstract
A device and method include an enclosure having a top layer with an external touch surface and an oppositely disposed back surface, a flexible substrate including a first portion affixed to the back surface, a second portion separate from the first portion, and an intermediate portion between the first second portions. An array of capacitive sensors is configured to sense objects proximate the external surface. A processor mounted to the second portion is configured to obtain signals from the sensors, determine object motion proximate the external surface using the signals, cause scrolling in response the object moving along a first axis, cause continued scrolling in response to the object lifting with a substantially non-zero speed along the first axis, and to not cause continued scrolling in response the object lifting with a substantially zero speed along the first axis.

16. A capacitive sensing device comprising:
-
an enclosure, the enclosure including a top layer having an external surface and an internal surface opposite the external surface, wherein the external surface comprises a touch surface; a substrate including a first portion affixed to the external surface by adhesive, a second portion spatially separate from the first portion, and a bendable portion extending between the first portion and the second portion; and an array of capacitive sensors on the first portion of the substrate, the array of capacitive sensors configured to sense objects proximate the touch surface in at least one dimension. - View Dependent Claims (17, 18)

19. A method of providing an output using a capacitive device comprising an enclosure, the enclosure including a top layer having an external touch surface and an oppositely disposed back surface, a flexible substrate including a first portion affixed to the back surface, a second portion spatially separate from the first portion, and an intermediate portion extending between the first portion and the second portion, an array of capacitive sensors on the first portion of the flexible substrate configured to sense objects proximate the external surface, and a processor mounted to the second portion of the flexible substrate, the method comprising:
-
obtaining signals from the array of capacitive sensors; determining motion of an object proximate to the external surface using the signals; causing scrolling in response the object moving along a first axis; causing continued scrolling in response to the object lifting from the external surface with a substantially non-zero speed along the first axis; and not causing continued scrolling in response the object lifting from the external surface with a substantially zero speed along the first axis. - View Dependent Claims (20)
