Including Surface Acoustic Detection Patents (Class 345/177)
  • Patent number: 11366552
    Abstract: A polarizer disposed between a transducer and a surface in which acoustic waves propagate can be used to filter out certain types of acoustic energy. For example, the polarizer can be used with a shear-polarized transducer to pass shear waves and filter out compressional waves that may interact with water, thereby improving water rejection. In some examples, the polarizer can include one or more layers of piezoelectric material with a poling direction different than (e.g., orthogonal to) the poling direction of the transducer. Energy of compressional waves may be extracted by one or more external electric circuits. In some examples, the polarizer can be a magneto-elastic polarizer. In some examples, the polarizer can be a mechanical polarizer.

  • Patent number: 11334196
    Abstract: Acoustic touch and/or force sensing system architectures and methods for acoustic touch and/or force sensing can be used to detect a position of an object touching a surface and an amount of force applied to the surface by the object. The position and/or an applied force can be determined using time-of-flight (TOF) techniques, for example. Acoustic touch sensing can utilize transducers (e.g., piezoelectric) to simultaneously transmit ultrasonic waves along a surface and through a thickness of a deformable material. The location of the object and the applied force can be determined based on the amount of time elapsing between the transmission of the waves and receipt of the reflected waves. In some examples, an acoustic touch sensing system can be insensitive to water contact on the device surface, and thus acoustic touch sensing can be used for touch sensing in devices that may become wet or fully submerged in water.

    Abstract: The simple gesture control of the user interface can be used by visually impaired or blind people in order to enter telephone numbers or account numbers for example. The user interface and the method constitute a shift from the current paradigm of guiding a user on touchscreens, which has precisely the advantage of the handeye coordination allowed by the touchscreen, wherein a user touches the exact location on the touchscreen where a corresponding selection surface is visualized. Instead, a swiping gesture is supported which can be carried out in any region on the touch-sensitive surface and shifts the focus from one selection surface or virtual button to the next. The swiping gesture can be carried out not just in the horizontal and vertical direction but also in a diagonal direction. Diagonal swiping gestures allow a particularly quick selection of the corresponding virtual buttons.

  • Patent number: 10642370
    Abstract: An electronic device (1) such as a cell phone, or a proximity detector for an electronic device (1), has an ultrasound transmitter (5), an ultrasound receiver (6), and a processing system. It transmits an ultrasonic sine-wave signal from the transmitter (5), and receives the ultrasonic sine-wave signal, through air, at the receiver (6). It detects when the frequency of the transmitted signal and a frequency of the received signal satisfy a predetermined difference criterion, and uses this to determine whether to disable or enable a touch or touchless input (2) on the device (1).

  • Patent number: 10599267
    Abstract: Examples relate to improving unintended touch rejection. In this manner, the examples disclosed herein enable recognizing a touch on a touch-sensitive surface, capturing a set of data related to the touch, wherein the set of data comprises a set of spatial features relating to a shape of the touch over a set of time intervals, and determining whether the recognized touch was intended based on a comparison of a first shape of the touch at a first time interval of the set of time intervals and a second shape of the touch at a second time interval of the set of time intervals.

  • Patent number: 10572024
    Abstract: A head-mounted display (HMD) tracks a user's hand positions, orientations, and gestures using an ultrasound sensor coupled to the HMD. The ultrasound sensor emits ultrasound signals that reflect off the hands of the user, even if a hand of the user is obstructed by the other hand. The ultrasound sensor identifies features used to train a machine learning model based on detecting reflected ultrasound signals. For example, one of the features is the time delay between consecutive reflected ultrasound signals detected by the ultrasound sensor. The machine learning model learns to determine poses and gestures of the user's hands. The HMD optionally includes a camera that generates image data of the user's hands. The image data can also be used to train the machine learning model. The HMD may perform a calibration process to avoid detecting other objects and surfaces such as a wall next to the user.

  • Patent number: 10564420
    Abstract: A system and method that allows an electronic pen to interact with projected content in midair without the need for a tangible surface. The pen has a holographic projector that is extendible into a position where it forms a holographic surface and a content projector that is oriented to project content onto the holographic surface formed by the holographic projector. The electronic pen body includes a slot dimensioned to house said holographic projector. The holographic projector can be connected to the pen by a mechanical linkage that locks the holographic projector into position. The electronic pen has sensors for detecting and measuring movement of the pen as well as detecting and measuring user contact with the pen to detect and respond to dynamic movements used to interact with the displayed content.

  • Patent number: 10534530
    Abstract: A method implemented in a device including a position input sensor is provided, for generating ink data including stroke objects that are vector data configured to reproduce paths formed by operating a pointer. The method includes generally three step. The first step receives pen event data representative of a user's hand-drawn motion on a sensor surface. The second step generates a stroke object based on the pen event data, generates a metadata object that describes the stroke object based on the pen event data and context information received from an application supporting the pen event data, and generates a drawing style object that defines how to draw the stroke object based on the pen event data and the context information. The third step outputs the stroke object, the metadata object, and the drawing style object in association with each other in a recording format or in a transmission format.

  • Patent number: 10488990
    Abstract: An acoustic touch device able to distinguish between user finger touches and other noise-making events includes ultrasonic transmitting and receiving units, and a controller. The ultrasonic receiving unit generates low-frequency electrical signals when the acoustic touch device is touched by an external object or affected by acoustic noise. The low frequency electrical signals cause variation in the output electrical signals of the ultrasonic receiving unit. The controller is configured to power on or power off the ultrasonic transmitting unit according to such variation.

  • Patent number: 10459064
    Abstract: A system for determining the location of a mobile receiver unit includes static transmitter units, each including a respective clock which it uses to transmit a positioning signal according to a respective transmission schedule. The mobile receiver unit receives a positioning signal from any of the static transmitter units. A first processing means uses information relating to the received positioning signal to determine the location of the mobile receiver unit. A second processing means uses information relating to a respective drift and/or offset of each of the clocks of the static transmitter units to generate transmission schedules for the static transmitter units. Each transmission schedule instructs a respective static transmitter unit to transmit a positioning signal at one or more scheduled times according to the clock of the static transmitter unit.
