20080232068 | HEAT DISSIPATION DEVICE HAVING A FIXING BASE - A heat dissipation device includes a heat sink and a fixing base for securing the heat sink to a heat-generating device. The heat sink includes a base and a pair of flanges formed on two opposite sides of the base. The fixing base includes a pair of side plates formed on a first set of two opposite sides thereof. A pair of resilient barbs extends inwards from an end portion of each side plate. The fixing base is placed on the heat sink and the resilient barbs tightly clasp first two opposite sides of the heat-generating device to press the base of the heat sink towards the heat-generating device. The flanges of the base of the heat sink abut second two opposite sides of the heat-generating device to avoid movement of the heat sink along a direction perpendicular to the flanges. | 09-25-2008 |
20120093260 | METHOD AND DEVICE FOR TRANSMITTING SIGNAL - Embodiments of the present invention disclose a method and a device for transmitting a signal, and relate to the field of communications. The technical solutions provided by the embodiments of the present invention are: the method for transmitting a signal, including: determining a peak clipping threshold of a signal according to f(MCS), where MCS represents a modulation and coding scheme (MCS) of the signal, and f(MCS) is a corresponding relationship between the MCS and noise at a receiving end; performing peak clipping on the signal by using the peak clipping threshold to obtain a peak-clipped signal; and transmitting the peak-clipped signal. According to the embodiments of the present invention, different peak clipping thresholds may be selected according to different MCSs, and thus, the reliability of data transmission is improved. | 04-19-2012 |

The method includes: an IP address of a base station and a mask of the base station are acquired; an IP address of a routing gateway is determined, wherein the IP address of the routing gateway and an address of an OMC server are on a same network segment; and a route from the OMC server to the base station is obtained according to the IP address and the mask of the base station and the IP address of the routing gateway. A system for configuring a route to a base station in an OMC is also described. With the method and system, a base station can communicate with an OMC server, and can download and update a version automatically. | 05-15-2014 |
20140184394 | COMMUNICATION DEVICE AND METHOD FOR CONTROLLING ELECTRONIC DEVICE - In a method of controlling locking or unlocking of an electronic device using a communication device, a control protocol between the communication device and the electronic device is established, and locking commands of the electronic device are preset. The locking commands are sent to the electronic device to lock the electronic device when a signal of locking the electronic device is received by the communication device, and an unlocking command is sent to the electronic device to unlock the electronic device when a signal of unlocking the electronic device is received by the communication device. Finally, the control protocol between the communication device and the electronic device is terminated. | 07-03-2014 |
20140188256 | COMMUNICATION DEVICE AND METHOD FOR CONTROLLING ELECTRONIC DEVICES - In a method of controlling electronic devices, a communication device communicates with one or more electronic devices and a cloud server in a communication network. The communication device searches the one or more electronic devices in the communication network and sets a control rule list. The control rule list includes identification information of the one or more electronic devices, and control commands and control times for the one or more second electronic devices. The communication device uploads the identification information of the one or more electronic devices and the control rule list to the cloud server. The cloud server sends the control rule list to the one or more electronic devices according to the identification information. Then, each of the one or more electronic devices is controlled by executing the control commands in the control rule list when corresponding control times reach. | 07-03-2014 |
20150074112 | Multimedia Question Answering System and Method - An embodiment provides a multimedia question answering system and method. The system includes a question input unit, configured to receive a text question input by a user, a parsing unit, configured to acquire feature information and a semantic category of the text question, a category determining unit, configured to determine whether the semantic category exists in a preset multimedia database. The system further includes a similarity acquiring unit, configured to, when a determination result is yes, match the feature information with all text features corresponding to the semantic category in the database, so as to acquire a similarity between each text feature and the feature information. The system also includes a multimedia answer output unit, configured to acquire a corresponding text feature when the similarity is greater than a preset threshold, and output multimedia answer information corresponding to the text feature and prestored in the multimedia database. | 03-12-2015 |
20150109838 | Synchronous Rectifier Control Circuit and Synchronous - A synchronous rectifier control circuit an includes a current transformer (CT), a bridge rectifier, and a comparator, where the CT is connected in series to a secondary side, performs sampling on a loop current of the secondary side to obtain a current detection signal, and outputs the obtained current detection signal to the bridge rectifier; the bridge rectifier acquires a secondary-side sampling current according to the current detection signal, and outputs the secondary-side sampling current to the comparator so that the comparator generates a voltage difference; and an output signal of the comparator turns over so as to control on and off of a synchronous rectifier transistor. In this way, high-speed and high-precision control over a synchronous rectifier transistor can be implemented. The control is simple and is low in cost. | 04-23-2015 |
