Patents by Inventor Zhaoyuan Ma

Zhaoyuan Ma has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11163362
    Abstract: An electronic device may include a housing (100), a display (102) disposed in the housing (100) and including an interface surface (112) arranged for user contact and a reference haptic (108). The interface surface (112) includes an active haptic output that provides a time-dependent haptic output and a reference haptic (108) disposed on the housing or the interface surface to provide a time-independent haptic output related to the time-dependent haptic output. The combination of active and reference haptics on an electronic device, such as a wearable display device, can convey information to a user without requiring the user to look at the device.

  • Patent number: 10242821
    Abstract: Disclosed herein are techniques and systems for providing simulated, haptic feedback that is local to physical, non-actuating keys of a keyboard. A keyboard includes a plurality of non-actuating keys defined in a cover portion of the keyboard, a plurality of force-producing mechanisms coupled to a substrate underneath and adjacent the cover portion. The force-producing mechanisms may be positioned on suspended portions of the substrate that are mechanically isolated and arranged on the substrate to substantially correspond to a layout of the plurality of non-actuating keys. The force-producing mechanisms may be individually actuated to deflect the suspended portions of the substrate underneath the cover portion to create a tactile sensation for a user's finger that is local to a particular key. In some embodiments, the force-producing mechanisms are piezoelectric actuators.
