A ball-collecting device with ball-collecting module that includes a collecting component (10) and one or more collecting module (20) is disclosed. The collecting component has a compartment for accommodating one or more sports ball in which sports balls can be collected into the compartment by rotating the collecting component. The ball-collecting module is pin-jointed on the collecting component, thus forming an angle between the collecting component and its rotation axis (X), wherein the angle is smaller than or equal to 90 degrees. A constant distance is maintained between the ball-collecting module and the flat surface when the device of the present invention collects the sports balls.

In this study, the characteristics of the three-dimensional heat and fluid flow fields generated by the vibrating fan are examined by performing numerical simulations and experimental measurements. This paper considers two different arrangements of the heat source, namely vertical and horizontal. In performing the simulations, the fluid domain is meshed using a dynamic meshing scheme in order to take account of the time-varying shape and position of the vibrating blade. The results show that the interaction between the normal force exerted on the air surrounding the moving blade and the impingement jet flow produced at the blade tip prompts the formation of two counter-rotating screw-type flow circulations on either edge of the blade. An infrared thermal camera is used to measure the temperature distribution on the heated surface to examine the numerical results. It is indicated that the piezoelectric fan improves the heat transfer coefficient by 1.6-3.4 times when the heat source is vertically arranged and 1.8-3.6 times when the heat source is horizontally arranged. © 2012 Elsevier Ltd.

This paper studies the bifurcation and nonlinear behaviors of a united gas-lubricated bearing (UGB) system by a hybrid numerical method combining the differential transformation method and the finite difference method. The analytical results reveal a complex dynamic behavior comprising periodic, sub-harmonic, quasi-periodic and chaotic responses of the rotor center. Furthermore, the results reveal the changes which take place in the dynamic behavior of the bearing system as the rotor mass and bearing number are increased. The current analytical results are found to be in good agreement with those of other numerical methods. Therefore, the proposed method provides an effective means of gaining insights into the nonlinear dynamics of UGB systems. © 2011 Elsevier Ltd. All rights reserved.

Piezoelectric fans consist of a thin flexible blade attached to a vibrating piezoelectric patch, and provide an effective means of enhancing the heat transfer in low convective regions. In this study, the characteristics of the three-dimensional heat and fluid flow fields generated by the vibrating fan are examined by performing numerical simulations and experimental measurements. In performing the simulations, the fluid domain is discretized using a dynamic meshing scheme to take account of the time-varying shape and position of the vibrating blade. The results show that two counter-rotating screw-type flow structures on either side of the blade appeared on either edge of the blade, and a pair of asymmetric vortex is formed around the fan tip. The experiment is conducted with a total of eighteen T-type thermocouples attaching to the cylindrical surface to measure the variation of temperature. The experimental and numerical results indicate that the piezoelectric fan improves the heat transfer coefficient by 1.2-2.4 times. Moreover, the augmentation of local heat transfer coefficient can be achieved by 2.85 times. © 2012 Elsevier Ltd. All rights reserved.

A massaging shoe pad, which comprises a base layer, a plurality of first plates and a plurality of second plates, is disclosed. The base layer has a plurality of accommodation spaces having a first opening and a second opening located at two sides of the base layer respectively. A plurality of first plates is disposed in each accommodation space and one end of each first plate is connected to the side wall of each accommodation space respectively. The other end of each first plate protrudes out of the first opening and forms the first protrusion. Between the two ends, each first plate protrudes out of the accommodation chamber, which has through holes, toward the second opening. A plurality of second plates is disposed in each accommodation space and one end of each second plate is moveably inserted through the through hole. The other end of each second plate protrudes out of the first opening and forms the second protrusion. When the second plate is moved from a first location to a second location, the second protrusion props against the other end of the first plate.

A heat transfer component with dendritic crystal structures and a purpose and method of use for such a component; this component is used to resolve the deficiency concerning conventional heat transfer components possessing inadequate surface areas for heat dissipation. Dendritic crystal structure is comprising: a substrate and multiple dendritic crystals. The substrate contains multiple preset crystal defects in which all the dendritic crystals deposit and congregate, and a space is located between each dendritic crystal for thermal convection. Regarding the method of use, the substrate is connected to a heat source, which then induces directional heat transfer from the substrate and the metal layer to the main branch and at least one sub-branch of the dendritic crystal, or the dendritic crystal is placed on a heat source, which induces heat transfer from the crystal to the substrate.

A growth method of dendritic crystal structure that provides directional heat transfer, including the steps: A. providing a substrate, whereby the substrate is provided with a plurality of crystal defects; B. depositing a plurality of metal ions on the substrate using a deposition method, whereby the metal ions on the crystal defects enable the growth of dendritic crystals. Moreover, an interspace is provided between each of the dendritic crystals. Hence, when the substrate is in contact with a heat source, heat energy is transferred from the substrate in the growth direction of the dendritic crystals; or, when the dendritic crystals are disposed at the position of a heat source, heat provided by the heat source is transferred from the dendritic crystals in a direction toward the substrate. Accordingly, the fractal structure of the dendritic crystals is used to provide ample heat dissipation areas and contact areas.
