The adjustment unit is coupled to the determining unit and the buffer unit, for adjusting the used depth of the buffer unit according to the determining result. | 01-12-2012 |
20130117586 | NETWORK ACCESS DEVICE WITH FLEXIBLE PRECISE LOW-POWER REMOTE WAKE-UP MECHANISM APPLICABLE IN VARIOUS APPLICATION LAYER HANDSHAKE PROTOCOLS - A network access device is disclosed, having a transceiving circuit, a demodulation circuit, and a control circuit. The transceiving circuit is used to receive network signals. The demodulation circuit is coupled with the transceiving circuit and used to generate data frames according to the network signals. The control circuit is coupled with the demodulation circuit and used to wake up one or more components of an electronic device when at least two fields of the data frame match predetermined values, or when the data frames are received in a predetermined order. | 05-09-2013 |
20140289393 | NETWORK APPARATUS AND CONNECTION DETECTING METHOD THEREOF - A network apparatus and a connection detecting method thereof are disclosed. The network apparatus receives a network connection request which determines a wireless network connection between a USB network controller and a wireless network access point. The network apparatus determines a network connection frequency band of the wireless network connection according to the network connection request, and switches a data transmission mode of the USB network controller from a first USB operation mode to a second USB operation mode after determining that an operation frequency of the first USB operation mode conflicts with the network connection frequency band. | 09-25-2014 |
20140297899 | UNIVERSAL SERIAL BUS NETWORK INTERFACE CONTROLLER AND OPERATION MODE SWITCHING METHOD - A universal serial bus (USB) network interface controller and an operation mode switching method thereof are provided. The USB network interface controller determines an access point network band of a wireless network access point with which the USB network interface controller intends to connect, and switches from a first USB operation mode to a second USB operation mode to transmit data with a host so that an operation frequency of the USB network interface controller falls outside the access point network band. Afterwards, the USB network interface controller adjusts an operation network band to be the same as the access point network band, and exchanges information with the wireless network access point. | 10-02-2014 |
20150058500 | COMMUNICATION APPARATUS AND RELATED SIGNAL RECEIVING APPARATUS - A communication apparatus includes a host, a signal receiving apparatus arranged to receive a wireless signal, and a connecting device coupled between the host and the signal receiving apparatus. The connecting device is arranged to transmit a transmission signal between the host and the signal receiving apparatus. The signal receiving apparatus refers to the state of the received wireless signal to control the connecting device to selectively enter a second operation mode from a first operation mode to reduce the interference upon the wireless signal. | 02-26-2015 |
