摘要： Methods and systems are disclosed that relate to ranking functions for multiple different domains. By way of example but not limitation, ranking functions for multiple different domains may be trained based on inter-domain loss, and such ranking functions may be used to rank search results from multiple different domains so that they may be blended without normalizing relevancy scores.

摘要： A start-up circuit in a switch-mode power converter that employs a Zener diode to provide a reference voltage to reduce the power consumption and the size of the start-up circuit. The start-up circuit also includes a coarse current source and a coarse reference voltage signal generator for producing current and reference voltage for initial startup operation of a bandgap circuit. The reference signal and current from coarse current source and the reference voltage signal generator are subject to large process, voltage and temperature (PVT) variations or susceptible to noise from the power supply, and hence, these signals are used temporarily during start-up and replaced with signals from higher performance components. After bandgap circuit becomes operational, the start-up receives voltage reference signal from the bandgap circuit to more accurately detect undervoltage lockout conditions.

摘要： A method and apparatus for ATM network planning is described. ATM network planning involves designing an ATM network to support traffic demands, which may include voice, data, image and video traffic. It is desirable to design a backbone network for a metropolitan area which minimizes the total network cost. The design process includes the determination of network topology, location and configuration of switches, dimensioning of all links, etc. A heuristic method is described which provides a near-optimal lowest cost network design with the cost reasonably certain to be close to the optimal solution. The advantage is a versatile method which can reliably produce a lowest cost network plan in a reasonable time.

The method includes: receiving a multicast data stream sent by a data server; and monitoring in real time a receiving rate of a terminal connected to an access point, if the receiving rate is higher than or equal to a multicast sending rate at which the access point sends multicast data, sending, in a multicast mode, the multicast data stream sent by the data server to the terminal, and if the receiving rate is lower than the multicast sending rate, converting the multicast data stream sent by the data server into a unicast data stream and sending the unicast data stream to the terminal. In the solution, the mode of sending multimedia data stream by the access point is determined according to the receiving rate of the terminal, which improves the transmission quality of the multimedia data stream and enhances the user experience.

摘要： A hydraulic jack capable of displaying load and overload warning, belonging to the technical field of hydraulic lifting equipment. It comprises: a base, a lifting arm, a pump body, a handle, and a tray, wherein, a signal collection assembly designed to sense the load on the tray is arranged at the end of the lifting arm, and the signal collection assembly is electrically connected to a weighing controller arranged on either the base or the pump body, and the tray is arranged on the signal collection assembly. Since a signal collection assembly designed to sense the load on the tray is arranged at the end of the lifting arm and electrically connected to the weighing controller, the load sensing method by the aid of communication with the oil circuit in the prior art is abandoned and the leakage of hydraulic oil can be avoided; since the signal collection assembly is arranged at the end of the lifting arm, the entire assembly can be easily processed, installed, and maintained.

摘要： A controller integrated circuit (IC) for controlling a power converter uses its input voltage pin with a plurality of functions, including receiving an input voltage to the power converter, charging an external startup capacitor through charging circuitry coupled internally to the input voltage pin, and also receiving a test signal for programming a programmable resistance in an input voltage scale down circuitry coupled to the input voltage pin. Use of the input voltage pin with a plurality of functions reduces the number of pins required in the controller IC, thereby reducing the cost of manufacturing the controller IC.

摘要： The present provides a soymilk machine/juicer with grinding function, comprising a pair of concentric rotator (13) and stator (14) that are vertically arranged in a house. There are at least two thread convex ribs (16) on said rotator (14), and the thread convex ribs (16) are evenly distributed on the outer surface of a rotator body (15). Rotary clearance is defined between the thread convex ribs (16) of the rotator (13) and the inner wall of the stator (14). The middle upper part of said rotator body (15) is a revolved portion with small upside and large downside. The clearance of the upside of the rotator body (15) corresponding to an upper filter net (17) on the stator (14) is largest, which is the smashing section for dealing with stuff after stuff is fed. The clearance of the middle part of the rotator body (15) corresponding to the middle upper part of an abrasive disc of the stator (14) is medium-size, which is for smashing stuff further. The clearance of the middle lower part of the rotator body (15) corresponding to the lower part of the abrasive disc of the stator (14) is gradually shortened to less than 1 mm, which is the grinding section for stuff. The part of the rotator (13) under the grinding section corresponding to a lower filter net (18) on the stator (14) is the separating section for the soymilk from residue. The rotator of said soymilk machine/juicer can rotate stably and have less noise, and stuff can be grinded to be finer.
