  • Publication number: 20220043553
    Abstract: A signal driving method is provided, configured for a stylus to send a driving signal to a touch screen, where the driving signal is configured for the touch screen to determine location information and/or pressure information of the stylus on the touch screen. The method includes: the stylus detecting an uplink signal sent by the touch screen according to a first signal driving mode; and the stylus switching from a first signal driving mode to a second signal driving mode according to a detection result of the above uplink signal.

  • Publication number: 20220011883
    Abstract: A method and an apparatus for pressure detection, an active pen, a touch control chip and an electrode device are provided, configured to detect a pressure of the active pen on a screen. The active pen includes a pressure sensor, a wireless communication module and a tip electrode, and the pressure sensor is configured to detect the pressure generated by the active pen. The method includes: determining a second pressure level corresponding to the pressure, according to a detection signal corresponding to a first driving signal output by the tip electrode, when a pressure signal of a first pressure level corresponding to the pressure sent by the wireless communication module is not received; and displaying handwriting of the active pen, by the screen, according to the second pressure level. The method can reduce time delay of a response of a first writing of the active pen.

  • Publication number: 20220011916
    Abstract: The present application provides a synchronization method. The method includes: transmitting, by a first wireless communication chip of the electronic device, a synchronization signal to a second wireless communication chip of the active pen and simultaneously transmitting a first indication signal to a touch control chip of the touch screen; where the first indication signal is used to instruct the touch control chip to detect a driving signal transmitted by the active pen after from reception of the first indication signal, the second wireless communication chip is further configured to transmit a second indication signal to a driving chip of the active pen while receiving the synchronization signal, the second indication signal is used to instruct the driving chip to transmit the driving signal after from reception of the second indication signal, the second preset duration is less than the first preset duration.

  • Patent number: 11093083
    Abstract: The present disclosure relates to touch technology, and provides a method for preventing an edge from being unintentionally touched, a touch control apparatus and a storage medium. The method comprises: acquiring touch data of a touch screen in real time; judging whether there is any edge touch operation according to the touch data; calculating a coordinate point movement track of the edge touch operation according to the touch data if there is an edge touch operation; judging whether the edge touch operation is an edge mis-operation according to the touch data and the coordinate point movement track; and suppressing the edge mis-operation if the edge touch operation is an edge mis-operation. With embodiments of the present disclosure, accuracy of edge mis-operation recognition is improved while ensuring a normal response of an edge region of a screen.

  • Publication number: 20170245464
    Abstract: A pet feeding bowl may include a main body and an inner portion. In one embodiment, the main body is bowl-shaped with a receiving space. The main body also includes a holding portion at the bottom thereof. In an exemplary embodiment, the inner portion is also bowl-shaped with a receiving space. The inner portion is configured to dispose in the receiving space of the main body. The inner portion can be further secured at the main body when a predetermined amount of liquid is placed on a back side of the inner portion, so when the back side of the inner portion is in contact with the bottom portion of the receiving space, a surface tension will hold the inner portion to the receiving space to further secure it thereon.
