摘要:
A method for determining the position of touches on a touch sensor is described including receiving values from a touch sensor, converting the values to binary data, identifying one or more contiguous touched regions, extracting parameters from each touched region that related to the shape and location of each region, and determining the validity of each region. The method also includes obtaining data from the contiguous touched regions at a later time and linking the data of the two times for the touched regions to create a series of temporal parameters. The data for the temporal parameters is filtered to remove noise, and the position of the touches is determined from the temporal parameters.

A drop analysis/drop check system allows a plurality of printheads to remain stationary during analysis to emulate operation of an actual piezoelectric microdeposition system. The system provides accurate tuning of individual nozzle ejectors and allows for substrate loading and alignment in parallel with drop analysis/drop check. The drop analysis/drop check system includes a motion controller directing movement of a stage, a printhead controller controlling a printhead to selectively eject drops of fluid material to be deposited on a substrate, and a camera supported by the stage for movement relative to the printheads. The camera receives a signal from the motion controller to initiate exposure of the camera and captures an image of the drops of fluid material ejected by the printheads. A light-emitting device includes a strobe controller that receives a signal from the camera to supply light to an area including the liquid drops during camera exposure.

According to the present disclosure, a printer apparatus may include a chuck configured to support a substrate thereon, a rail spaced apart from the chuck, a printhead carriage frame coupled to the rail and containing a printhead carriage housing at least one printhead therein, a first camera assembly configured to capture image data of the printhead and provide the image data to a computer, and a computer receiving the image data from the first camera assembly and configured to determine a deviation between a desired position of the printhead and an actual position of the printhead.
