摘要： A location of contact with a touch sensitive device is determined. Values associated with each electrode of a plurality of electrodes formed on a single layer of the touch sensitive device are sampled. A determination is made as to whether a contact with the touch sensitive device has occurred. Values sampled subsequent to the contact are adjusted based on selected stored sampled values. A location of contact is then determined based on the adjusted values.

摘要： A touch sensor comprises a substrate capable of propagating acoustic waves and includes a first surface having a touch sensitive region. A first sidewall intersects the first surface along a first edge. The first edge is configured to propagate a first acoustic wave along the first edge. The first acoustic wave may be a one-dimensional edge wave. A wave converter converts the first acoustic wave to a second acoustic wave, and the first surface is configured to propagate the second acoustic wave across the touch sensitive region.

摘要： Radial transducers are provided for acoustic touch sensors. Different radial transducer arrangements may allow for locating multiple simultaneous touches without ambiguity, in some embodiments without a bezel. Instead of transmitting acoustic waves along a line to be reflected at multiple points, surface acoustic waves are transmitted in a radial wave pattern. Surface acoustic waves are transmitted along different angles spread out over at least part of the touch region. Various techniques may be used to generate the radial wave pattern, such as a convex wedge of a wedge transducer, interference patterns, a curved piezoelectric element, a curved reflector, a curved edge of the substrate, a curved grating, or one or more lenses. These devices for controlling the spread of the surface acoustic waves may alternatively be used for control of the surface acoustic rays for transmission along a single line or just along two lines (e.g., X and Y axes).

摘要： A computer readable medium has instructions to calibrate a touch system by detecting touch points on a touchscreen that are each associated with touchscreen coordinates in a touchscreen coordinate system. The instructions associated each of the touch points with known calibration targets, and each of the calibration targets has display coordinates in a display coordinate system that is associated with at least one of a display screen and an operating system. The instructions fit the display coordinates and the touchscreen coordinates non-linearly with respect to each other based on a generalized Laplace-constrained fit that is used to identify correction parameters used to map a user generated run-time touch point on the touchscreen to a display coordinate location on a display screen. The correction parameters represent non-linear corrections.

摘要： A bending wave touch system includes at least one sensor and a touchscreen controller. The at least one sensor is coupled to a substrate and is responsive to vibrations in the substrate. The at least one sensor outputs signals. The controller receives the signals from the at least one sensor and identifies touch coordinates based on high frequency components of the signals when a touch on the substrate includes at least one of a tap, a drag and a lift-off. The controller identifies a status of a hold condition of the touch based on at least two different time averages of low frequency components of the signals.
