Disclosed are methods for managing a power in a wireless network communication. One of the methods provides checking whether information on a request for a mode change is received for a prescribed channel time in a manner that a device configuring a network enters a power save mode in the course of not performing data transmission / reception and that a modem enters an awake state from a sleep state for the prescribed channel time. And, the prescribed channel time is determined to correspond to a time for transmitting a beacon. According to a preferred embodiment, a modem of a device in a power save mode enters an awake state for a channel time period for broadcasting a beacon and then checks whether information on a power management mode change is received. If the information does not exist, a sleep state is reentered. If the power management mode change (PMMC) information is received, a power is managed by performing data transmission / reception in a manner of switching to a normal mode.

In a content distributed-storage system in which divided content data obtained by dividing content data of a single unit having a plurality of pieces of frame image data into a plurality of pieces is stored so as to be distributed to a plurality of node devices, unique identification information is assigned to each of the divided content data, each of the node devices can obtain the divided content data on the basis of the identification information.In the system, content catalog information having the identification information of at least one piece of the divided content data and key frame information including information indicative of an offset position of the frame image data in each of the divided content data, is stored. An instruction related to playback of the content data from the user is received.

A shift control system for hybrid vehicles which is constructed to transmit a motive energy of the prime mover to a wheel via a clutch and a transmission, comprises an electric power generating means for generating an electric power by the motive energy of the prime mover, and for supplying the generated electric power to an electric motor, when executing a gear shift of the transmission and transmitting the motive energy of the motor to the wheel.

The invention relates to a workshop production plan scheduling system and method oriented to discrete manufacturing. The system comprises a workshop plan scheduling system arranged in a workshop, wherein the workshop plan scheduling system is connected with manufacturing units used for finishing a work order plan, an ability group units and other equipment, and the manufacturing units, the ability group units and other equipment are arranged in the workshop; the workshop plan scheduling system is also connected with a warehouse system, an ERP (Enterprise Resource Planning) or MRP (Manufacturing Resource Planning) system, a human resource system and a process system; the ERP or MRP system is connected with the workshop plan scheduling system through an interaction module; and the interaction module is used for issuing a production plan and reporting a workshop production plan finishing situation in real time. By use of the system, production factors, including an equipment load, an equipment calendar, a process flow, a manufacturing beat, a work order transferring way and the like, are comprehensively considered, a practical production task is split into each executable work order, the manufacturing time and the manufacturing amount of each work order are set for each work order, an enterprise manager can be more favorably assisted in tracking and monitoring a whole production process, and meanwhile, the convenience and the maneuverability of production dispatching and scheduling are both given consideration.

A control method of a robot comprises the following steps of detecting the operating parameters of the robot, generating fault information when the operating parameters are abnormal, sending the fault information to a remote service center, and receiving fault solution information returned by the remote service center. When the robot breaks down, a user can know the fault timely and can remotely learn a fault elimination method, the robot does not need to be sent to a maintenance service department to be detected and maintained every time, and convenience is brought for the user.

The invention provides an intelligent plate part machining production line provided with universal equipment and special equipment. Four special machining tools and a universal machining tool are sequentially and linearly arranged from an automatic feeding device, wherein the four special machining tools are located on a first station, a second station, a third station and a fourth station, and the universal machine tool is located on a fifth station; a truss conveying transport device is arranged behind the first station, the second station, the third station and the fourth station in parallel, and four mechanical arms are arranged on the truss transport device to transfer materials on the corresponding stations; a four-axis manipulator is arranged between the fourth station and the fifthstation and is used for transferring the materials between the fourth station and the fifth station and discharging finished products; industrial cameras are arranged on the second-station mechanicalarm and the four-axis manipulator and are used for recognizing defective products; waste boxes are arranged between the first station and the second station as well as between the fourth station andthe fifth station and are used for storing the defective products; a discharging box is arranged on the front side of the fifth station and is used for storing the finished products; and a scrape conveying mechanism is arranged below the whole production line and is used for collecting and transferring scrapes. According to the intelligent plate part machining production line, the universal equipment and the special equipment are combined, and flexible clamps and sliding rail cylinders are used, so that the production line is flexible, the machining times of the stations are balanced, and theproduction efficiency is improved.

The invention discloses method and device for preventing a thread from blocking. The method includes: after a system starts, replacing all application program interface functions used for awaiting events to be triggered so that, when one replaced application program interface function is transferred by a thread, if that the length of set waiting time is unlimited is determined, changing the length of the set waiting time to a preset value; or after a system starts, replacing all application program interface functions used for ending events so that, when one replaced application program interface function is transferred by a thread, if that critical sections occupied by the thread to be ended is not released is determined, then releasing the critical sections; or performing thread poll periodically, if that the length of blocking time of a thread exceeds a preset length of time and the thread is blocked on transferring of application program interface functions used for occupying critical sections, then releasing a critical section corresponding to a first parameter of the transferred application program interface functions. By the method, successfully execution of the program can be guaranteed.
