When the second host starts and the first host does not start, the peripheral devices are controlled by the second host.
Abstract:
A method for adjusting the working frequency of a chip is provided. The method detects a frequency adjustment range of a graphic chip when a system is booted. Then, an application program in full screen mode is executed, and a control hot key is enabled. Afterwards, an input of the control hot key is received to display a user interface. Finally, an input frequency inputted from the user interface is received, and the working frequency of the graphic chip is adjusted according to the input frequency in the frequency adjustment range. Therefore, even though the application program is executed in full screen mode, the working frequency of the graphic chip can still be adjusted according to requirements in any time, which is convenient for the user.
Abstract:

Each of the antenna units includes a rectangular radiation region, a first feeding line and a second feeding line. The first and second feeding lines are connected to two adjacent feeding corners of the rectangular radiation region. The first connection line and the second connection line are disposed at two sides of the antenna unit for connection with the other ends of the first feeding line and the second feeding line, respectively.
Abstract:
A controllable power supply device with a step-up function including a constant voltage generator, a programmable voltage generator, a first switch and a linear regulator is provided. The constant voltage generator is used to provide an initial voltage. The programmable voltage generator is used to receive the initial voltage and adjust the received initial voltage to boost the initial voltage to a power supply voltage. The first connecting terminal of the first switch is used to receive the initial voltage, the second connecting terminal of the first switch is used to receive the power supply voltage, and the third connecting terminal of the first switch is coupled to one of the first connecting terminal and the second connecting terminal. Therefore, the voltage from the third connecting terminal of the first switch is stabilized and is outputted as the output voltage of the controllable power supply device by the linear regulator.
Abstract:
A Chinese character input device and method thereof are described. The Chinese character input device includes a database, a touch panel and a processing module. The database stores multiple candidate characters, multiple initial consonants and multiple rhymes. Each candidate character is composed of at least one initial consonant and at least one rhyme. The touch panel displays a virtual keyboard including initial consonant virtual keys and rhyme virtual keys and receives a command. The command includes a touch on an initial consonant virtual key to determine an input initial consonant and a release at a rhyme virtual key to determine an input rhyme. The processing module is connected to the database and compares the input initial consonant and input rhyme with the initial consonants and rhymes in the database to generate at least one corresponding candidate character and displays the candidate character on the touch panel for selecting.
Abstract:
A notebook computer includes a host, a supporting frame and a display portion. The supporting frame is pivotally connected with the host and comprising a sliding slot. The display portion has a sliding member, which is pivotally connected with the supporting frame and slidably connected with the sliding slot, wherein the sliding member comprises a through hole. The signal cable is led through the through hole and extended within the supporting frame to electrically couple the display portion and the host. The signal cable comprises a bendable section. The signal cable is moved substantially along a plane by adjusting a bent angle of the bendable section when the display portion is slid along the sliding slot.
Abstract:
A resistive touch panel and a method for detecting the touch point type are disclosed. The resistive touch panel has multiple detecting areas. The method includes the following steps: obtaining the positions of multiple touch points when a touch operation is generated on the touch panel; determining whether the touch points can be combined to be a combined touch point when the touch points are located at adjacent areas; and determining whether the combined touch point is a first-type touch point or a second-type touch point when the touch points can be combined to be the combined touch point.
Abstract:
An electronic device and a connector thereof are provided. The electronic device includes a circuit board and an electronic device and the connector disposed on the circuit board. The connector includes a slot and a cap. The slot is configured for a card module to be plugged in along a plugging direction. A first pillar portion and a second pillar portion are at two opposite sides of the slot. The cap is disposed on a top of the first pillar portion and has a first protruding portion. The first protruding portion protrudes out of a side of the first pillar portion away from the second pillar portion while observing along the plugging direction.
Abstract:
The invention discloses a method for detecting touch point type in a resistive touch panel. The method includes the steps of: connecting the first electrode to a voltage source and connecting the fourth electrode to the ground end when it is determined that a touch point is generated on the first detecting area, thereby making the second electrode generate a first voltage and the third electrode generate a second voltage; determining that the touch point is the first-type touch point when the difference between the first voltage and the second voltage is larger than a threshold value; and determining that the touch point is the second-type touch point when the difference between the first voltage and the second voltage is smaller than a first threshold value.
