Abstract: A control device is provided. A membrane switch of the control device is specially designed. A cured ink member is formed on a surface the upper film layer facing the lower film layer or a surface of the lower film layer facing the upper film layer by using a UV printing process. Due to the ink member, a specified gap or distance between the upper film layer and the lower film layer can be maintained when they are not contacted with each other or when the membrane switch is not triggered.

Abstract: A function parameter switching memory circuit for a peripheral device is provided. The peripheral device includes a function parameter switching memory circuit, a power management device and an optical sensor. The function parameter switching memory circuit includes a function parameter switching key and a simulation control circuit. The function parameter switching key generates and outputs a physical switch signal in response to a switching trigger action of a user. The simulation control circuit generates a virtual switch signal to the optical sensor. The simulation control circuit analyzes the physical switch signal to memorize a switched-and-set function parameter storage value. The simulation control circuit generates the virtual switch signal according to one of the physical switch signal and the switched-and-set function parameter storage value. The optical sensor performs a function parameter switching process according to the virtual switch signal.

Abstract: A method for establishing a wireless connection between an electronic device and a computer host is provided. Firstly, a near field communication between a NFC reader of the computer host and a NFC tag of the electronic device is performed. Then, a Bluetooth wireless communication between the electronic device and the computer host is performed, and the NFC tag is disabled. Consequently, the NFC tag is not repeatedly read by the NFC reader. In other words, the use of the electronic device is more convenient.

Abstract: A mouse device includes a lower cover, a circuit board, a first switch, a second switch, a first swinging element, and a second swinging element. The first swinging element includes a first pressing part and a second pressing part. The first swinging element and the second swinging element are located at a front side and a rear side of the lower cover, respectively. As the mouse device is swung in a leftward direction or a rightward direction, the front side and the rear side of the mouse device are simultaneously tilted. Moreover, since the first pressing part or the second pressing part of the first swinging element is pushed by a working surface where the mouse device is placed, the first pressing part or the second pressing part is moved toward the first switch or the second switch in order to trigger the first switch or the second switch.

Abstract: A mouse device includes a casing and a roller module. The roller module is disposed within the casing. The roller module includes a scroll wheel, a magnetic ratchet, a supporting element and a permanent magnet. The scroll wheel includes a concave structure. The magnetic ratchet is disposed within the concave structure of the scroll wheel. While the scroll wheel is rotated, the magnetic ratchet is correspondingly rotated. The magnetic ratchet includes a ratchet frame and plural tooth structures. The plural tooth structures are discretely arranged on an inner surface of the ratchet frame. While the magnetic ratchet is rotated with the scroll wheel, the plural tooth structures of the magnetic ratchet are sequentially transferred through a region over the permanent magnet, and a magnetic attractive force between the corresponding tooth structure and the permanent magnet is generated.

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.

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.
