  • Patent number: 10698504
    Abstract: A stylus pen that can be used as an input device to a digitizer associated with a computer screen on a computing device, such as a computer, mobile device, tablet, etc. The stylus pen can include an end cap that has multiple pressure thresholds for implementing different user-input commands. To detect the pressure being applied to the end cap, the cap is movable relative to a stylus pen body so as to move a plunger in proximity or contact with a mechanical switch. The mechanical switch is a single-action switch that is converted to a dual-action switch by using the electrical conductivity of the switch to detect an electrical coupling between a plunger and the switch. The electrical coupling can be in the form of a capacitive coupling or a direct electrical connection. Further pressure can be detected through actuation of the mechanical switch.

  • Patent number: 10671190
    Abstract: A stylus pen is disclosed that can detect touch signals from a digitizer and dynamically determine which digitizer (e.g., make/model) generated the touch signals. The stylus pen can then switch to one of a plurality of candidate protocols, without interaction from the user, so as to communicate with the digitizer. The digitizer need not explicitly communicate what protocol it supports to the stylus pen. Rather, the stylus pen analyzes the digitizer waveforms and compares the waveforms to known signatures to determine which digitizer is being used. The stylus pen can then dynamically set a protocol used to communicate with the digitizer that matches the protocol expected by the digitizer.

  • Patent number: 10589564
    Abstract: An adaptor allows a user to turn any pencil or pen into a capacitive stylus while still allowing it to write on paper. When attached to a pencil, pen or similarly shaped and purposed tool, it gives the tool the added capability of operating electronic devices having a capacitive touch screen. It does this while constantly maintaining the writing instrument's intrinsic capability of marking paper. The main component of the invention comprises a fastener which allows electricity to pass along it while simultaneously allowing the writing utensil tip to be permanently exposed. It can transfer electricity from the user's hand to the touch screen without interfering with the original function or ergonomic shape of the writing instrument. A seamless workflow between surfaces is created since the same end of the writing instrument is used and no other action is required to reveal or conceal its tip.

    Abstract: Methods and apparatuses are provided for determining a pitch and yaw of an elongated interface object relative to a proximity sensitive surface. In one aspect, a proximity image is received having proximity image data from which it can be determined which areas of the proximity sensitive surface sensed the elongated interface object during a period of time. A proximity blob is identified in the proximity image and the proximity image is transformed using a plurality of different transformations to obtain a plurality of differently transformed proximity images. A plurality of features is determined for the identified blob in the transformed proximity images and the pitch of the elongated interface object relative to the proximity sensitive surface is determined based upon the determined features and a multi-dimensional heuristic regression model of the proximity sensitive surface; and a yaw is determined based upon the pitch.

  • Patent number: 10522049
    Abstract: A synchronous displaying method and a synchronous displaying apparatus are provided. An ability to transmit at any time is possessed by intercepting screen content at regular time and performing compression, which improves transmission effects and shortens transmission time. A comparison of the intercepted screen content and intelligent determining on the synchronous image is performed by using eigenvalues parsed and obtained during image compression. In addition, synchronous transmission is realized automatically without manual operations. Moreover, the transmission of repeated screen content is avoided to the greatest extent, which reduces storage pressure on student user terminals and ensures content comprehensiveness. Further, marking and judging on the screen image content improve the efficiency of student reviews. For example, students can directly see the last few pages of each blackboard-writing during reviews.

  • Patent number: 10514785
    Abstract: An active stylus includes a signal processing section. The signal processing section during operation in a first mode, while supplying a downlink signal DS1, obtained by modulating a pulse train signal with a pen pressure level P, to an electrode, determines whether it is necessary to switch to a second mode. The signal processing section during operation in the second mode, while supplying a downlink signal DS2, obtained by modulating a sine wave signal with the pen pressure level P, to the electrode, determines whether it is necessary to switch to the first mode. The signal processing section switches to operation in the second mode when determining that such is necessary, and switches to operation in the first mode when determining that such is necessary. The active stylus may be used with two position detection devices, one supporting only the first method and the other supporting only the second method.
