  • Patent number: 10481735
    Abstract: An optical touch-sensitive device is able to determine the locations of multiple simultaneous touch events. The optical touch-sensitive device includes multiple emitters and detectors coupled with an optical coupler assembly through a waveguide on the surface on the optical-touch sensitive device. Each emitter produces optical beams which propagate in the waveguide via total internal reflection and are received by the detectors. Touch events disturb the optical beams, and are determined based on the disturbances. The waveguide has at least one dead zone on its surface. The dead zone is formed with a cover layer having a top surface and a bottom surface where the bottom surface of the cover layer is directly coupled to the top surface of the waveguide. The cover layer preserves optical beam propagation in the waveguide and makes the dead zone insensitive to touches on the top surface of the cover layer.

  • Patent number: 10330766
    Abstract: When the excitation frequency of a touch panel and the frequency of external noise match or are close, noise cannot be removed by a bandpass filter. In addition, when a touch detection operating period is limited to a short period such as the no addressing period, the signal-to-noise ratio (S/N) decreases because frequency separation decreases and the noise removal effect by averaging is degraded. An electronic device of the present invention includes a sensor system (101), an excitation generator (102) that generates an intermittent sinusoidal signal and applies this signal to the sensor system, and a demodulator (105) that demodulates the amplitude modulated signal that is the output of the sensor system.

  • Patent number: 10013119
    Abstract: The shape or position of an object is estimated using a device comprising one or more transmitters and one or more receivers, forming a set of at least two transmitter-receiver combinations. Signals are transmitted from the transmitters, through air, to the object. They are reflected by the object and received by the receivers. A subset of the transmitter-receiver combinations which give rise to a received signal meeting a predetermined clarity criterion is determined. The positions of points on the object are estimated using substantially only signals from the subset of combinations.

  • Patent number: 10007341
    Abstract: A touch interface device includes a touch surface configured to be engaged by an object, first and second actuator assemblies operably connected to the touch surface, and a controller operably connected with the first and second actuator assemblies. The first actuator assembly displaces the touch surface in one or more lateral directions along the touch surface at a first frequency. The second actuator assembly displaces the touch surface in an angled direction that is one of at least obliquely or perpendicularly angled to the touch surface at a second frequency. The controller operates the first and second actuator assemblies so that the touch surface varies in engagement with the object to impart a force on the object that is along the touch surface.

  • Patent number: 9984271
    Abstract: An electronic device that includes an enclosure having an external surface and a first array of ultrasonic transducers arranged along a first direction and a second array of ultrasonic transducers arranged along a second direction. The first array of ultrasonic transducers may be configured to produce a surface wave along the external surface. A set of scattered waves may be created by the touch on the external surface. The second array of ultrasonic transducers may be configured to receive a portion of the set of scattered waves and produce an output. The device may also include a processing unit that is configured to identify the touch using the output. The processing unit may be further configured to create a reconstruction of at least a portion of a fingerprint associated with the touch on the cover, and to identify the fingerprint using the reconstruction.

  • Patent number: 9897682
    Abstract: A synchronization system for an acoustic signal-based positioning system is provided that generates a magnetic field as a synchronization signal. The magnetic synchronization signal is transmitted by a transmitter of the positioning system and received by the receiver of the positioning system. The receiver may include a magnetic synchronization signal receiver that may receive the magnetic synchronization signal on a same acoustic channel as an acoustic positioning signal. Moreover, the magnetic synchronization signal receiver may be a component already present in the receiver and capable of receiving a magnetic synchronization signal.

  • Patent number: 9891738
    Abstract: An electronic device that senses home button inputs through ultrasonic force sensing. The electronic device may correlate that amount of force that a user applies to the home button with a specific home button command. In certain embodiments, the system may combine the force of touch information with other information that is sensed for a particular touch to correlate the touch input with a greater number of home button commands. A home button embodiment discussed herein may include a home button image that is displayed on a touch sensitive panel. In other embodiments, a home button may be located outside of the boundaries of a touch sensitive panel.

  • Patent number: 9857917
    Abstract: A touch-sensitive apparatus operates by light frustration (FTIR) and comprises a light transmissive panel (1) with a front surface and a rear surface. Light emitters (2) and light detectors (3) optically face the rear surface along a perimeter of a touch-sensitive region (4) on the panel (1). At least one diffusively reflecting element (40) is arranged on the front surface (5) along the perimeter of the touch-sensitive region (4). The light emitters (2) are arranged to emit a respective beam of light onto the diffusively reflecting element (40), so as to generate propagating light that propagates by total internal reflection inside the panel (1) across the touch-sensitive region (4), and the light detectors (3) are arranged to receive detection light generated as the propagating light impinges on the diffusively reflecting element (40), so as to define a grid of propagation paths (D) across the touch-sensitive region (4) between pairs of light emitters (2) and light detectors (3).
