Patterns of sensor elements that can be used in capacitance sensing devices are described. A plurality of sensor elements extends in a radial direction from a shared center. A first subset of the sensor elements extend like spirals in a clockwise direction, and a second subset of the sensor elements extend like spirals in a counterclockwise direction.

One embodiment in accordance with the invention includes a capacitive sensor apparatus that includes a first sensing element having substantially constant width along its length and configured to have varying capacitive coupling to an object proximate to a capacitive sensing reference surface, along a first axis of the capacitive sensing reference surface. The length of the first sensing element is oriented along the first axis. The capacitive sensor apparatus can include a second sensing element having substantially constant width along its length and configured to have varying capacitive coupling to the object proximate to the capacitive sensing reference surface along the first axis. The length of the second sensing element is oriented along the first axis. The first and second sensing elements are conductive, and are configured to provide information corresponding to a spatial location of the object relative to the first axis of the capacitive sensing reference surface.

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.

One embodiment in accordance with the invention includes a capacitive sensor apparatus that includes a sensing element and a ground element. The capacitive sensor apparatus also includes a floating strike ring that is electrically isolated from the sensing element. The floating strike ring and the ground element form a spark gap. The spark gap is for reducing potential damage to the capacitive sensor apparatus that can be caused by an electrostatic discharge encountered by the capacitive sensor apparatus.

One embodiment in accordance with the invention includes a two-dimensional capacitive sensor apparatus. The two-dimensional capacitive sensor can include a first sensing element having varying width, a second sensing element having varying width, and a third sensing element having varying width. Additionally, the first sensing element, second sensing element, and third sensing element are substantially parallel to a first axis. Furthermore, each of the first sensing element, second sensing element, and third sensing element can be located such that they are not required to overlap each other to determine a first location along the first axis of a two-dimensional space. Moreover, the first sensing element, second sensing element, and third sensing element can have a cumulative width that is substantially constant.
