Abstract:
An optical touchscreen includes a transparent panel, a plurality of optical modules, and at least one retro-reflector. The transparent panel includes a first surface and a second surface opposite to each other, a plurality of corners, and a plurality of edges. The optical modules are respectively disposed on the corners, and each optical module includes an incident-light unit and a sensor. The incident-light unit is used for emitting an incident light, so that the incident light enters and passes through the transparent panel via total reflection between the first surface and the second surface. The sensor is disposed on one side of the incident-light unit. The retro-reflector is disposed on the edges, and the retro-reflector is used to reflect the incident light, so that the incident light is reflected by the retro-reflector, and the reflected incident light goes in a reversed path within the transparent panel and is captured by the sensor.
Abstract:
A mold for forming tilt boss includes a slider part, a main part and a core pin. The slider part is formed with a tilt groove. The main part is formed with a tilt channel. When the slider part and the first main part are engaged, a tilt-boss forming cavity is formed. The tilt-boss forming cavity is communicated with the tilt channel and coaxial with the tilt channel. The core pin penetrates the tilt channel and one distal portion thereof is slidably engaged with the tilt groove, another distal portion thereof is protruded into the tilt-boss forming cavity. When the slider part is separated from the main part for allowing the core pin to be moved from a high point to a low point of the tilt groove, the core pin is downwardly moved along the tilt channel.
Abstract:
A computer and a control method thereof are provided. The computer includes a power button, a flash read-only memory (ROM), a processor, a near field communication (NFC) module, a chipset, and a coprocessor. The flash ROM stores a power button protection state for the power button. The chipset is coupled to the processor and the flash ROM. The coprocessor is coupled to the power button, the NFC module, and the chipset. The coprocessor verifies whether a current user identification (UID) of a NFC card equals a default user identification (UID) after the NFC module generates an interrupt request (IRQ). The coprocessor changes the power button protection state when the current UID equals the default UID.
Abstract:
A remote upgrade server having a networking module and a processing unit is provided. The networking module provides a network access service. The processing unit receives an update checking request from a mobile communication device via the networking module, and determines a delay time period according to a current networking load in response to the update checking request. Also, the processing unit transmits an update configuration file including the delay time period to the mobile communication device via the networking module, so that the mobile communication device downloads the system update file from the remote upgrade server after the delay time period.
Abstract:
A communication system and method are provided. In the communication system, a first electrical device has an end point which is configured to connect to a plurality of 3G dongles, wherein the 3G dongles have different IP addresses; a cloud server integrates the IP addresses to generate an integrated IP address when the cloud server detects that the first electrical device is connected to the 3G dongles; and a second electrical device transmits data packets with the first electrical device via the integrated IP address through the cloud server.
Abstract:
A printed circuit board structure includes a plurality of circuit layer plates stacked together in which each of the stacked circuit layer plates includes an epoxy resin plate body and a fabric structure completely encapsulated in the epoxy resin plate body, and each circuit layer plate stacked between two circuit layer plates is further provided with filler particles distributed in its epoxy resin plate body, and the two opposite and outermost circuit layer plates thereof have metal soldering pads on the outer surfaces of the epoxy resin plate body thereof, and the two opposite and outermost circuit layer plates do not have the filler particles in its epoxy resin plate body thereof.
Abstract:
A portable computer and an operating method thereof are provided. The portable computer comprises an input device, a power button, a non-volatile memory, a central processing unit (CPU), an embedded controller (EC), and a chipset. The input device inputs a user password, and the non-volatile memory stores a default password. The EC, in a soft off status, determines whether the power button protection item is enabled. The EC locks the power button if the power button protection item is enabled. The EC determines whether the user password is the same as the default password. The EC unlocks the power button if the user password is the same as the default password. The chipset is coupled to the non-volatile memory, the CPU and the EC.
Abstract:
Disclosed are an inter-device communication transmission system and a method. The inter-device communication transmission system includes a first-communication platform disposed in a first electronic device and a second-communication platform disposed in a second electronic device. When the first electronic device installs an application program, the first-communication platform selectively transmits the application program to the second-communication platform, so that the second-communication platform can install the application program. When the second electronic device executes a function of the application program, the second-communication platform transmits a command corresponding to the function to the application program installed in the first electronic device through the first-communication platform, and the command is executed by the application program to retrieve data. The first-communication platform transmits the data to the second-communication platform, and the second-communication platform transfers the data to the application program in the second electronic device for display of the data.
Abstract:
A power management method for a server system is provided. At least any one of a power status indication signal and an alert signal from a power supply is detected to judge whether an input voltage is normal. If it is judged that the input voltage is abnormal, a motherboard sends the power status indication signal to a battery backup unit (BBU) to inform the BBU to supply power to the motherboard. If it is judged that the input voltage is abnormal, the motherboard lowers its loading.
