摘要： A touch sensor, having an acoustic wave transmissive medium having a surface and a touch sensitive portion of the surface, a transducer system for emitting acoustic energy into the medium, and a receiver system for receiving the acoustic energy from the substrate as at least two distinct sets of waves, a portion of each of which overlap temporally at the receiver system or overlap physically by propagating in the touch sensitive portion along axes which are substantially non-orthogonal, the receiver system determining a position or a waveform perturbing characteristic of a touch on the touch sensitive portion. The receiver may be an amplitude detector or be sensitive to a phase-amplitude characteristic of the received acoustic waves.

摘要： A touch input system, comprising a surface, adapted to receive at least one simultaneous touch inputs from human fingers; a sensor adapted to detect the at least one touch inputs and produce at least one signal representing a unique position for the at least one touch input; and a processor, adapted to receive the at least one signal and produce an output representing a touch detection and a mapping of a coordinate position on the surface for each of the simultaneous touch inputs. The system may detect, for example, two touch inputs simultaneously. The surface may be non-planar and distinct from a small solid angle section of a sphere.

摘要： A touch sensor having an acoustic substrate, an acoustic transducer, and an acoustically diffractive grating is provided. The grating is disposed between the transducer and the substrate, so that acoustic energy from the transducer is coupled to an acoustic wave propagating along the surface of the substrate. If used in a display device, the combination of the transducer and grating may provide a low profile that allows the assembly to be more easily placed between the acoustic substrate and a bezel placed in front of the substrate. No acoustic components need be mounted on the rear surface of the substrate, allowing the acoustic substrate to be formed on the front surface of the display device.

摘要： A touch sensor comprises a substrate capable of propagating acoustic waves. The substrate includes a first surface having a touch sensitive region and a first sidewall intersecting the first surface at a first edge. A transmitter is provided on the first sidewall of the substrate. The transmitter generates acoustic waves that propagate directly from the first sidewall through at least a portion of the touch sensitive region.

摘要： A resistive touchscreen having a programmable display, such as an emissive display matrix of organic light-emitting diodes, or a reflective electronic paper display, built into the coversheet. The touchscreen may be of any resistive type, including 4-wire, 5-wire, and diode 3-wire. A touch/display system is thus provided in which there is little or no degradation of the displayed image due to image transmission through the internal touch sensor components, and in which the internal touch sensor components may be constructed of opaque materials.

摘要： An acoustic touch position sensor having a transducer which imparts a wave, propagating along a first axis. A reflective array disposed along the first axis which reflects the wave as a set of waves having a horizontally polarized component and a non-uniform volumetric energy density along an axis normal to said surface, traveling along a different axis into the touch surface region of the substrate. The waves are partially absorbed, attenuated or perturbed by an object touching the substrate, to create a modified waveform having characteristics indicative of the axial displacement and/or contact condition of the object with the substrate. The wave perturbation is detected by collecting the set of waves with a reflective array, which redirects the wave energy to a receiving transducer. The transducers preferably produce and are responsive to Rayleigh type waves, with the reflective arrays mode-converting acoustic wave energy between higher order horizontally polarized shear waves and Rayleigh type waves.
