A method and apparatus for detecting touch input at a touch sensor is provided. The touch sensor comprises a plurality of row traces, a plurality of column traces and an intersection corresponding to an identified row trace of the plurality of row traces and an identified column trace of the plurality of column traces. The touch sensor also includes at least one driver for driving the plurality of column traces and at least one reader for reading the plurality of row traces. The drivers and the readers scan the identified intersection by entering into a with-floating scan state, reading a first value for the identified row trace, entering into a without-floating scan state and reading a second value for the identified row trace. The presence of a touch input is accordingly determined based on the first and second values.

A method and apparatus for identifying an edge of a target object using laser distance measurement. The method comprises rotating a laser distance measuring head in intervals of a predetermined angle in a first direction. Further, at each step of rotation, directing a scan beam onto the target object at a point of incidence and measuring a distance between the laser distance measuring head and the point of incidence. When a difference between a measured distance at a first step of rotation and a measured distance at a second step of rotation exceeds beyond a predetermined threshold value, identifying, that an edge of the target object has occurred at the point of incidence of the scan beam corresponding to the second step of rotation, wherein the second step of rotation precedes the first step of rotation.

A mobile device accessory for measuring a dimension is described. The accessory includes a housing having a mating feature that is adapted to mate with a corresponding mating feature of a mobile device. A measuring tape includes a detectable pattern thereon. The detectable pattern is related to the dimension. The accessory also includes a detector that generates a signal in response to detecting the pattern. A processor generates dimension data in response to receiving the signal. An interface transmits the dimension data to the mobile device.

Methods and apparatus are provided for an apparatus for inputting data. The apparatus comprises a detection circuit for providing a first reference voltage to a first and a second electrode of a first conductive layer of a resistive touch screen and providing a second reference voltage to a first and a second electrode of a second conductive layer of the resistive touch screen. The detection circuit maintains the first and second reference voltages under quiescent conditions and when the first and second conductive layers couple together. The method includes applying substantially equal voltages to the first and second electrodes of the first conductive layer of the resistive touch screen. Substantially equal voltages are applied to the first and second electrodes of the second conductive layer of the resistive touch screen. Approximately zero current is conducted in the first and second conductive layers under quiescent conditions.
