In an open innovation environment, complex equipment is always developed within a collaborative development network. Existing researches on collaborative development are mainly based on methodology of non-weighted static network, and assume that innovative search is independent with knowledge transfer and knowledge creation. This paper, based on scale-free network, establishes a new model to more...
This letter proposes a near-field communication (NFC) antenna for smartphones with a metal cover that includes an embedded narrow slot, therein splitting the metal cover into upper and lower sections. The proposed NFC antenna is a simple loop structure that is formed by incorporating a three-dimensional coupling strip with the upper edge of the metal cover in the lower section. Because this antenna...
The locomotion performances of a quadruped robot with compliant feet based on closed-chain mechanism legs are presented. The legs of this quadruped robot were made up of six-bar linkage mechanism with one degree of freedom. And a special foot trajectory could be gained through kinematic analysis and optimum design of the six-bar linkage mechanism. In order to reduce the impact force of quadruped robot's...
Millimeter wave gain equalizers were designed using microstrip shorted SIR (Stepped Impedance Resonator) and waveguide resonator respectively. Traditionally, millimeter wave gain equalizer is composd of waveguide with electromagnetic wave absorber in resonator. However, putting the wave absorber into resonator directly is very hard to control the reflection coefficient and the max attenuation point...
