20110151824 | WIRELESS COMMUNICATION DEVICE AND METHOD FOR SAVING ENERGY - An energy saving method applied to a wireless communication, the wireless communication comprising a RF unit to search for wireless network signals, the method includes steps of: detecting whether the RF unit finds the wireless network signals; counting a length of time the RF unit does not find the wireless network if the RF unit does not find the wireless network signals; determining whether the length of time the RF unit does not find the wireless network reaches a predetermined search time limit; and turning off the RF unit if the length of time the RF unit dose not find the wireless network reaches the predetermined search time limit limit. | 06-23-2011 |
20120122417 | ELECTRONIC DEVICE HAVING FUNCTIONAL BLOCKS INDIVIDUALLY CONTROLLED TO SELECTIVELY ENTER POWER-SAVING MODE AND RELATED POWER CONTROL METHOD THEREOF - An electronic device includes a first functional block, a second functional block, and a control circuit. The first functional block has a first wake-up guard time requirement. The second functional block has a second wake-up guard time requirement which is different from the first wake-up guard time requirement. The control circuit is coupled to the first functional block and the second functional block, and implemented for selectively controlling the first functional block to switch from a normal mode to a power-saving mode by referring to the first wake-up guard time requirement, and selectively controlling the second functional block to switch from the normal mode to the power-saving mode by referring to the second wake-up guard time requirement. | 05-17-2012 |
20150056941 | COST EFFECTIVE MULTIBAND RF FRONT-END ARCHITECTURE FOR MOBILE APPLICATIONS - One embodiment of the present invention provides an RF front-end system. The RF front-end system includes one or more RF front-end components and a programmable logic device, which has a baseband interface for coupling to a baseband digital signal processor (DSP), and a set of component interfaces for coupling to the one ore more RF front-end components. The programmable logic device is configured to: receive, from the baseband DSP via the baseband interface, a command which includes an address and a control signal; identify a component interface from the set of component interfaces based on the address; and send the control signal to the identified component interface, thereby enabling the baseband DSP to control a front-end component coupled to the programmable logic device via the identified component interface. | 02-26-2015 |
20150381297 | ACTIVATING A DIGITAL RADIO BROADCAST RECEIVER IN A VEHICLE - A system and method of controlling a digital radio broadcast receiver in a vehicle includes: detecting an instruction to activate the digital radio broadcast receiver; accessing a software application at the vehicle in response to the instruction; and activating the digital radio broadcast receiver in the vehicle at the direction of the software application. | 12-31-2015 |

20090042531 | SIGNAL RECEIVER CIRCUIT - A signal receiver circuit including a transmission gate, a pull-low unit, a boost capacitor, a voltage division unit, and a receiver unit is provided. The transmission gate determines whether to conduct an input signal according to a control signal. The pull-low unit determines whether to pull down the voltage at a terminal of the boost capacitor according to the control signal. The boost capacitor boosts the input signal of the receiver unit. The voltage division unit sends a divided voltage to another terminal of the boost capacitor according to the control signal. When an input signal is received, the boost capacitor boosts the input signal, for overcoming low current issue caused by high threshold voltage of MOS transistors and accordingly the receiver unit achieves full swing. | 02-12-2009 |
