  • Patent number: 11231784
    Abstract: Touch-based input devices, such as a stylus, can provide feedback in the form of shear forces applied to the user. A stylus can produce shear forces that act on a user to provide unique tactile sensations. For example, a shear device can be included at a grip region of a stylus to provide shear sensations at the user's hands (e.g., fingers). The shear forces can be unaligned forces that urge one part of the user's hand in one direction and another part of the user's hand in an opposite direction or that tend to maintain the other part of the user's hand in a stationary location.

  • Patent number: 11205365
    Abstract: The present disclosure discloses an image data transmission apparatus having synchronous data transmission mechanism. Output stage circuits respectively receive and store image data corresponding to a part of a display frame. A primary switch circuit is coupled to a primary output stage circuit of the output stage circuits so as to maintain a control voltage of a control terminal at a first level when a primary frame aligning signal having the latest timing is not received from the primary output stage circuit, and switches the control voltage to a second level when the primary frame aligning signal is received. The output stage circuits output the image data to an image data receiving apparatus to display the display frame synchronously when the output stage circuits receive the control voltage having the second level through voltage transmission paths having the same signal transmission time.
