Abstract:
A centrifugal fan includes a centrifugal impeller, a first housing, a second housing, an annular guide ring and a driving device. The centrifugal impeller has a hub and blades connected to and disposed around the hub. The first housing and the second housing cooperatively define a hollow chamber and an air outlet. An air inlet is formed in a central section of the second housing. A first arc structure is located on an inner surface around the air inlet of the second housing. Support brackets respectively extend from an end close to a tongue of the second housing and an end away from the tongue of the second housing. The support brackets are perpendicular to the second housing. The annular guide ring has a second arc structure close to an outermost margin of inner surfaces of the blades. The driving device is used for rotating the centrifugal impeller.
Abstract:
A server includes a chassis, a main tray and a hard disk drive (HDD). The main tray is slidably connected to the chassis and is capable of pulling out of the chassis or pushing into the chassis along a first direction. The main tray includes an accommodating slot and a sub-tray. The sub-tray is slidably disposed inside the accommodating groove and when the main tray is pulled out of the chassis, the sub-tray can be slid along a second direction perpendicular to the first direction between an expanded position and a retracted position relative to the chassis. When the sub-tray at the expanded position, the hardware can be taken from the sub-tray or put on the sub-tray.
Abstract:
A head mounted system includes a physiological signal sensor, a signal processing circuit, a memory, an application processor, and an eyeglass frame. The physiological signal sensor monitors a physiological state to output a physiological signal. The signal processing circuit determines whether the physiological state is abnormal according to the physiological signal. When it is not abnormal, the signal processing circuit controls the physiological signal sensor to monitor the physiological state at a first monitoring frequency. When it is abnormal, the signal processing circuit outputs a warning signal, and controls the physiological signal sensor to monitor the physiological state at a second monitoring frequency greater than the first monitoring frequency. The application processor receives the warning signal and stores physiological data corresponding to the physiological signal in the memory. The eyeglass frame carries the first physiological signal sensor, the signal processing circuit, the memory, and the application processor.

The co-axial cable is fixed and electrically connected to the ground portion. The ground portion is fixed and electrically connected to a system ground plane. The ground portion is electrically connected to the metal protrusion portion.
Abstract:
A licensing platform is provided. The licensing platform, in communication with a first license sharing device and a second license sharing device, includes a license database and a main license sharing device. The license database provides a plurality of licenses. The main license sharing device includes: a license allocation manager, in communication with the license database, for dynamically managing a usage status of the plurality of licenses; a next-tier membership manager, in communication with the license sharing devices, for allocating at least one of the plurality of licenses to the license sharing devices, and updating a license usage status of the license sharing devices; and a license record manager, in communication with the license allocation manager and the next-tier membership manager, for recording the usage status of the plurality of licenses.
Abstract:
An electronic device includes: a plurality of parallel-connection battery groups; and a plurality of battery balance circuits, respectively coupled to the parallel-connection battery groups, when the parallel-connection battery group has a temperature over a predetermined temperature range, the battery balance circuit performs a thermal balance operation on the parallel-connection battery group so that the temperature of the parallel-connection battery group returns into the predetermined temperature range.
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.
