    Abstract: A stylus adapted to a touch panel is provided. The stylus comprises a barrel, a driving circuit disposed inside the barrel and configured to generate a driving signal, a conductive tip disposed at an end of the barrel and electrically connected to the driving circuit to receive the driving signal, and a conductive grip disposed at the barrel and electrically isolated from the conductive tip. The conductive tip is capacitively coupled with the touch panel via the driving signal to form a first induced capacitor on the touch panel. A capacitance effect is generated between the conductive grip and the touch panel to form a second induced capacitor on the touch panel. A touch control method is also provided.

    Abstract: A key structure includes a movable support element, a keycap, and a fitting portion. The keycap includes a top surface, a bottom surface, and a rim, the bottom surface is jointed with the movable support element, and a periphery of the top surface extends downward to form the rim. The fitting portion is located on the rim, and operated by an operation body to separate the keycap from the movable support element.

    Abstract: A signal transmission assembly includes a substrate, a first transmission line, and a second transmission line. The first transmission line and the second transmission line are disposed on the substrate and extending along a first direction. The first transmission line comprises at least one first transmission section and at least one second transmission section. The first transmission section is apart from the second transmission line by a first distance. The second transmission section is apart from the second transmission line by a second distance. The first distance is greater than or equal to the second distance. A first edge of the first transmission section and a second edge of the second transmission section are proximal to the second transmission line and parallel to the first direction, and the second transmission line does not contact an edge extension line extending from the second edge along the first direction.

    Abstract: A voltage conversion apparatus includes a power supply circuit with a first switch, a voltage conversion circuit, and a protective circuit with a detection circuit. The first switch transmits a power to generate an input voltage. The voltage conversion circuit generates a first voltage. A second switch of the voltage conversion circuit receives the input voltage. A third switch of the voltage conversion circuit is coupled between the second switch and a ground terminal. The detection circuit generates a first control signal based on the first voltage, a second voltage that corresponds to the first voltage, and a reference voltage. When a voltage value of an error signal is less than the reference voltage, the detection circuit outputs the first control signal to turn off the first switch. The voltage value of the error signal corresponds to a voltage difference between the first voltage and the second voltage.

    Abstract: Methods and apparatuses for improving uplink transmissions in a wireless communication system are disclosed herein. In one method, a user equipment receives an indication indicating a type of data that can be transmitted using a cooperation mode. A first data is transmitted using the cooperation mode, in which the first data belongs to the type of data using the cooperation mode based on the indication. A second data is transmitted without using the cooperation mode, in which the second data does not belong to the type of data using the cooperation mode based on the indication. The cooperation mode is enabled when transmitting the first and second data.

    Abstract: A method and apparatus are disclosed from the perspective of a UE (User Equipment). In one embodiment, the method includes the UE monitors or receives a control signal within a channel occupancy, wherein the control signal indicates a number of consecutive TTIs (Transmission Time Intervals) and TTI format(s) related information of the TTIs. The method further includes the UE derives transmission direction of symbols in the TTIs or functionality of symbols in the TTIs from the information. The method also includes the UE considers the last TTI of the indicated TTIs as an ending TTI of the channel occupancy. In addition, the method includes the UE performs DL (Downlink) data reception or UL (Uplink) data transmission until the ending TTI.
