Abstract:
An electronic device with a plurality of booting modes comprises at least a button unit, a control module, a control chip unit, a super I/O unit and a Basic Input/Output System (BIOS). One of the button units outputs a first signal according to a trigger event. The control module includes a buffer unit connected to the button units. The control module sets the buffer unit according to the first signal. The control module outputs a status signal and copies the first signal and outputs the first signal after a delay time. The control chip unit receives the status signal. The super I/O unit receives the first signal outputted from the control module and transmits the first signal to the control chip unit. When the control chip unit receives the status signal and the first signal, the BIOS executes the corresponding booting procedure according to the status signal.

Abstract:
A method and apparatus are disclosed for a relay UE to receive packets from an eNB where the relay UE acts as a relay for forwarding the packets between a remote UE and the eNB. In one embodiment, the method includes the relay UE connecting with the eNB. The method further includes the relay UE being configured with a radio bearer between the relay UE and the eNB. The method also includes the relay UE receiving a downlink packet on the radio bearer from the eNB, wherein the downlink packet is to be transmitted to the remote UE. In addition, the method includes the relay UE not transmitting any resource request to the eNB for requesting a SL grant for transmission of a sidelink packet including the downlink packet when the sidelink packet becomes available for transmission and there is currently no data available for transmission to the remote UE. Furthermore, the method includes the relay UE receiving the SL grant from the eNB. Also, the method includes the relay UE using the SL grant to transmit the sidelink packet to the remote UE.
Abstract:
A charging system includes a transmission line, a power adaptor, and an electronic device. The transmission line includes a first terminal and a second terminal. The power adaptor is coupled to the first terminal and generates a charging voltage and a first voltage signal. The charging voltage is at a first voltage level. The electronic device is coupled to the second terminal and receives the first voltage signal. When the first voltage signal is larger than a first preset voltage signal, the electronic device outputs a second voltage signal to the power adaptor. When the second voltage signal is larger than a second preset voltage signal, the power adaptor adjusts the charging voltage into a second voltage level.

Abstract:
An impeller which is applied to a fan includes a hub, a plurality of first centrifugal blade and a plurality of second centrifugal blades. The hub is disposed in an accommodating space of the fan. The first centrifugal blades and the second centrifugal blades are connected to the hub. The first centrifugal blades have first ends away from the hub. The second centrifugal blades have second ends away from the hub. A distance between the second end and a center of the hub is larger than that between the first end and the hub center, and the first centrifugal blades and the second centrifugal blades are arranged periodically. Thus, an airflow noise in a constant frequency generated by the impeller can be avoided, and noises in inconstant frequency would not accumulate or generate annoying noise peak.
