Abstract: A network automatic link backup method and a network system thereof are provided. The method can be applied to the network system including at least two spine switches. A backup link is established between the two spine switches. When original links fail, a backup mechanism inside the spine switch is performed. In the network system, each of the spine switches has a link failover group. When the spine switch receives packets from a host, the packets are analyzed to determine priority of each link towards the destination. Then the packets can be forwarded through a specific switch port based on the priority. However, when the link for the spine switch to forward the packets fails, in order to complete the transmission, the packets are transmitted to another spine switch via the backup link without the intervention of the software-defined network controller.

Abstract: A heat dissipating device includes a thermal conductive substance, a plurality of heat-radiating protrusions and a plurality of turbulence-generating structures. The thermal conductive substance has a first surface and a second surface opposite to the first surface. The heat-radiating protrusions are integrally formed with the thermal conductive substance on the first surface. At least one of the turbulence-generating structures is formed on the first surface of the thermal conductive substance in concaved manner, and arranged around a bottom periphery of the heat-radiating protrusions, so as to obstruct a development of a boundary layer around the bottom of the heat-radiating protrusions.

Abstract: A friction stir welding device, provided for welding stacked metallic boards together, includes a mounting seat and a plurality of friction-stir tools. The mounting seat is defined with a rotational axis-direction. Each friction-stir tool has a shoulder portion and a stirring probe protruded from the shoulder portion. The friction-stir tools are arranged in the rotational axis-direction and disposed on a bottom surface of the mounting seat. The friction-stir tools can rotate along the rotational axis-direction. When a relative linear motion is applied between the friction-stir tools and the stacked metallic boards, the shoulders of the friction-stir tools produce stirring-coverage zones which are overlapped partially along the linear movement direction, so that the stirring-coverage zones by the friction-stir tools form a planar welding zone. The present disclosure also provides a method of friction stir welding for welding stacked metallic boards together.

Abstract: A heat-dissipating device includes a base and a plurality of heat-dissipating members. The base is formed with a plurality of joint holes. Each heat-dissipating member has an inserting section and an exposed section connected with the inserting section. The inserting sections are inserted into the joint holes in a close fit manner, respectively. The exposed sections are exposed outside a top surface of the base. The ends of the inserting sections and the bottom surface of the base are welded by a friction stir welding (FSW) manner with a solid-state joining structure. The present disclosure also provides a method for manufacturing a heat-dissipating device, which joins the ends of the inserting sections and the bottom surface of the base by a friction stir welding manner.

Abstract: An automatic diagnosing method for the autonomic nervous system and a device thereof are described. The device comprises a sensor, a computing device and an output device. An electrode of the sensor is adhered to the skin surface of a subject to detect and output the heart beat signal of the subject. The computing device collects the heart beat signal from the electrodes through the signal collection leads. The computing device further amplifies, filters, digitizes and transforms the heart beat signals into a plurality of heart rate variability parameters. Further, calculations, validation and analysis are performed on these parameters. After selecting a corresponding diagnosis description statement from a lookup table in a database, an examination report, which incorporates the diagnosis description statement and the heart rate variability parameters is output.
