Abstract: A human body modelling method and apparatus and an electronic device. The method comprises: acquiring at least one human body image; extracting an original profile of a human body from the human body image; calculating a body surface profile of the human body according to the original profile; and constructing a three dimensional human body model according to the body surface profile. The establishment of a three dimensional human body model originates from two dimensional human body images, without using a human body scanner to scan a human body, which reduces the cost of establishing the three dimensional human body model. Moreover, there is no requirement for the position and dressing of a human body object, and the process of establishing the three dimensional human body model is more convenient.

Abstract: The present application discloses a 3D indoor modeling method based on point cloud data. After pre-processing the raw point cloud data, the normal vectors and curvature values of the point cloud data are obtained through local surface properties analysis. By 3D point segmentation, the initial planes can be obtained. After performing the room layout re-construction, an initial 3D model can be generated. Finally, in combination with the returned laser pulse and the distance between the wall surface-objects and the wall surface, the specific form of the wall surface-object is reconstructed to achieve high-precision 3D modeling of complex indoor scenes. The method does not need any prior knowledge in advance, and strengthens the recognition and re-construction of the specific form of the wall surface, particularly suitable for high-precision 3D modeling of indoor scenes with high complexity.

Abstract: In a wireless power transfer (WPT) system, a power-transmitting unit has a loop-shaped magnetic core formed by alternately arranging high-permeability (HP) and low-permeability (LP) core sections to give an interleaving pattern. A primary coil wound on the magnetic core provides a magnetic flux traveling therein when excited by an AC power source. A power-receiving unit has a pickup core shaped and dimensioned to overlie one or any LP core section, and to partially overlap HP core sections immediately adjacent to the LP core section that is overlay. The pickup core has a relative permeability higher than that of the aforesaid LP core section, causing at least a part of the magnetic flux to divert from this LP core section to the pickup core. The diverted part of magnetic flux generates electrical power in a secondary pickup coil wound on the pickup core to achieve WPT.

Abstract: A new ultrasonic aided laser joining method (UAL) for bonding dissimilar materials has been developed. The method is capable of eliminating the laser-induced bubbles at the bonding faces and to improve the joint strength over that of the conventional laser-assisted metal and plastic joining method (LAMP). Some experiments on joining titanium to polyethylene terephthalate have been conducted to show the superiority of UAL over LAMP. The results showed that the joint strength, measured in terms of failure load, was significantly increased when ultrasonic vibration was employed during laser joining. For the LAMP joined specimens, fracture normally occurred at the metal-plastic interface, whereas for the UAL joined specimens, fracture normally occurred in the parent plastic part. The improvement in joint strength is mainly due to the elimination of pores in the resolidified plastic.

Abstract: A client-server architecture is used in a multicore computer system to realize a single-core-equivalent (SCE) view. In the system, plural stacks, each having a core and a local cache subsystem coupled thereto, are divided into a client stack for running client threads, and server stacks each for running server threads. A shared cache having shared cache blocks, each coupled to the client stack and to one or more server stacks, is also used. The core of an individual server stack is configured such that computing resources utilizable in executing the server thread(s) are confined to the individual server stack and the shared cache block coupled thereto, isolating an inter-core interference caused by the server thread(s) to the client thread(s) to within the individual server stack, the shared cache block coupled thereto, any server stack coupled to this shared cache block, and the client stack to thereby realize the SCE view.
