摘要： The present invention discloses a method and system for implementing a three-dimension positioning. The method comprises: receiving, by an optical sensor, infrared rays emitted from an infrared reference light source; and determining a position of the optical sensor with respect to the infrared reference light source based on attributes of the infrared reference light source in images obtained by the optical sensor, so as to implement a three-dimension relative positioning of the optical sensor. The method and system determine the position of the optical sensor with respect to the infrared reference light source by means of the attributes of the infrared reference light source in the images, which are simple in implementation, of a relatively low cost and can provide an excellent positioning function for application contexts of relative positioning (such as immersive video), which greatly improves the experience of a user.

摘要： Sorting inquiry results includes, based on extracted inquiry results matching search conditions of a user, collecting features of the inquiry results. The collected features may be used as features of a respective inquiry result and feature fitting may be conducted based on a support vector machine (SVM) regression model to obtain a feature fitting value of the respective inquiry result. The inquiry results may be sorted based on relevancy values of the inquiry results, and, for inquiry results having a same relevancy level, the inquiry results may be sorted in a top-down manner based on feature fitting values of the inquiry results.

摘要： Various exemplary embodiments relate to a method and related system and machine-readable medium including one or more of the following: receiving, at the MEP, a connectivity fault management (CFM) message; determining whether the CFM message includes an indication specifying a new value for a timeout factor; and when the CFM message includes an indication specifying a new value for the timeout factor, using the new value as the timeout factor. One or more of the following may also be included: when the CFM message does not include an indication specifying a new timeout factor, using a default value as the timeout factor; determining a timeout period using at least the timeout factor; determining whether the timeout period has elapsed since a most recent CFM message was received; and when the timeout period has elapsed since the last CFM message was received, determining that a timeout has occurred.

摘要： The present invention relates to a method and system for simulating a handle's motion. The method comprising: receiving detected acceleration values x(i), y(i) and z(i) of the handle in three directions; determining whether the acceleration values x(i), y(i) and z(i) in the three directions are noise interference with reference to a threshold value NT for noise interference; in the case that the acceleration values x(i), y(i) and z(i) are not the noise interference, determining angles α(i), β(i) and γ(i) during the handle's motion respectively from the acceleration values x(i), y(i) and z(i); and simulating the handle's motion on the basis of the angles α(i), β(i) and γ(i). The method and system according to the present invention poses a big challenge to the conventional operation by a mouse or a keyboard. They can simulate every motion of a user and reflect the motion on a role in a 3D game. It is also possible that virtual animation created by the method has outstanding reality and good real-time characteristics without additional hardware circuits, so that the user gets released from the restriction by the mouse and keyboard.
