摘要： Methods and systems are provided for producing a light effect on a touchpad or other position sensor. In one aspect, a position sensor for detecting a position of an object suitably includes a sensor, a light source, and a light conductor at least partially located between the sensor and the object. The light conductor is configured to transmit light from the light source to produce a light effect that alters the appearance of the position sensor. Because the light conductor is located between the sensor and the object, the sensor need not be made from transparent or translucent material, thereby significantly reducing the cost of the sensor. In a further aspect, the position sensor includes at least one marking or pattern in proximity to the light conductor such that the marking can be made visible by at least a component of the light to produce an image of a soft control, logo, ornamental design, status indicator or the like.

One embodiment forms a first sensor electrode on a substrate. In addition, a first routing trace is formed on the substrate, the first routing trace coupled with the first sensor electrode. One embodiment additionally forms a second sensor electrode on the substrate. A second routing trace differing in length from the first routing trace is also formed on the substrate, the second routing trace coupled with the second sensor electrode. To attenuate electrical interference, the second routing trace is formed having an approximately equal RC time constant characteristic as the first routing trace.

摘要： One type of capacitive sensing apparatus has a sensing element that includes a first portion and a second portion adjacent opposite edges of a sensing region. Signals from the first and second portions are combined. Another type of apparatus includes: a first sensing element including first and second portions; a second sensing element including third and fourth portions; and a third sensing element including fifth and sixth portions. The first, third and fifth portions form a first pattern, and the second, fourth and sixth portions form a second pattern. The patterns are bilaterally symmetrical about a median of a sensing region. In another type of apparatus, an electrical conductor coupled to a first sensing element passes through a gap in a second sensing element. An electrical conductor coupled to the second sensing element is dimensioned such that a capacitive coupling to the second sensing element is compensated for the gap.
