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.
Abstract:
A method for managing electric quantity of a battery is disclosed. The method includes charging a battery normally with a 4.2V voltage when a temperature of the battery is lower than a first threshold temperature; charging the battery continuously when the temperature of the battery is higher than the first threshold temperature and lower than a second threshold temperature and the electric quantity of the battery is lower than a first threshold voltage. On the contrary, the battery is not charged any more when the temperature of the battery is between the first threshold temperature and the second threshold temperature and the electric quantity of the battery is higher than the first threshold voltage or a first capacity. If the temperature of the battery is higher than a second threshold temperature, the battery is not charged any more regardless of the battery voltage.
Abstract:
A method for changing a booting source when a first operating system is being executed is disclosed. The method is utilized in a computer system having a first storage device storing the first operating system and a second storage device storing a second operating system. The method includes: receiving a signal from the second storage device; detecting whether the second storage device is a target device; setting the second storage device as a booting device; rebooting; and executing the second operating system from the second storage device.
Abstract:
A power control circuit and a power control method applied to a computer system are disclosed. A regulator receives a first voltage, the regulator converting the first voltage to an embedded controller voltage when the regulator is enabled. A detecting and controlling circuit receives the first voltage and the button signal, and the regulator is enabled when the detecting and controlling circuit detects the button signal. An embedded controller connects to the regulator for receiving the embedded controller voltage and outputting the plurality of power control signals. The embedded controller sends a power on signal to the detecting and controlling circuit to keep the regulator enabled.
