  • Publication number: 20240071665
    Abstract: A wheel control mechanism includes a support base, a wheel module, a first magnetic module and a second magnetic module. The wheel module, the first magnetic module and the second magnetic module are installed on the support base. The first magnetic module generates a magnetic attractive force to attract a metal ratchet of the wheel module. By adjusting the position of the second magnetic module relative to the first magnetic module, the strength of the magnetic attractive force is changed. Consequently, the rotation of the wheel module results in a tactile feel or does not result in the tactile feel.

  • Patent number: 11797108
    Abstract: A mouse device includes a roller module. The roller module includes a base member, a scroll wheel, a magnetic conductor, a swingable arm, a driving motor and an actuating element. The scroll wheel is installed on the base member. The magnetic conductor is located beside the scroll wheel. When the scroll wheel is rotated, the magnetic conductor is correspondingly rotated. The swingable arm is installed on the base member. The swingable arm includes a magnetic element. The swingable arm is swingable relative to the magnetic conductor. When the swingable arm is swung to a first position, the magnetic element is aligned with the magnetic conductor. Consequently, a magnetic attraction force between the magnetic element and the magnetic conductor is generated. When the swingable arm is swung to a second position, the magnetic attraction force between the magnetic element and the magnetic conductor is eliminated.

  • Patent number: 11681379
    Abstract: A mouse device includes a wheel control mechanism and a control unit. The control unit is electrically connected with a magnetic force module and a rotating speed detector of the wheel control mechanism. Under control of the control unit, a first direction current or a second direction current is selectively provided to drive the magnetic force module. The flowing directions of the first direction current and the second direction current are opposite. Consequently, the rotating mode of the wheel control mechanism can be switched between different modes.

  • Patent number: 11604522
    Abstract: A dynamic data transmission format adjustment method is provided. Firstly, a peripheral device raw input data is acquired from a device main body of a wireless peripheral device. Then, the peripheral device raw input data is converted into a variable-bit-length peripheral device transmission data according to a dynamic data transmission format conversion rule. Then, a network transmission packet containing the variable-bit-length peripheral device transmission data is generated, and the network transmission packet is transmitted to a wireless receiver of the wireless peripheral device. Then, the variable-bit-length peripheral device transmission data in the network transmission packet is converted and restored into a fixed-bit-length peripheral device transmission data according to the dynamic data transmission format conversion rule. Then, the fixed-bit-length peripheral device transmission data is transmitted from the wireless receiver to a computer host.

  • Patent number: 11567591
    Abstract: A roller module includes a supporting seat, a scroll wheel, a linkage rod, a torsion spring, a first magnet, a second magnet and a coil. The scroll wheel is installed on the supporting seat. The linkage rod includes a fulcrum segment, a resisting segment and an effort segment. The torsion spring is connected with the resisting segment. The first magnet is arranged between the second magnet and the effort segment. The coil is arranged around the second magnet. When the roller module is in a tactile mode, the first magnet and the second magnet are close to each other, and the torsion spring exerts a pulling force on the resisting segment. Consequently, the resisting segment is contacted with a toothed region of the scroll wheel. When the roller module is in a non-tactile mode, the resisting segment is moved away from the toothed region.
