An embedded PV monitoring device comprises a data receiving unit, a processing unit, a simulating unit and an evaluating unit. An embedded PV monitor system comprises a PV unit, a sensing unit and an embedded PV monitoring device. An embedded PV monitor method mainly utilizes the monitoring device to receive voltage and current parameters of the PV module and an environment working parameter. An output current and an output power of the PV module can be actually calculated, while the output current and the output power of the PV module can be simulated and estimated according to the voltage parameter and the environment working parameter. Thus, the field test monitoring and evaluating on the PV module can be automatically performed and a warning message can be timely outputted. This is advantageous to the detection of the yield of the PV module and the increase of the production quality.

A reusable hanging device includes: an adhesion layer, a plate layer, and a hook body. Wherein, the adhesion layer is a low stickiness soft plastic made of a thermoplastic elastomer composite material, and it is vacuum-absorbed onto a smooth surface of a wall or a smooth surface of a wall having tiny bumps, by means of the super strong friction force produced on the smooth surface of a wall by the atmospheric pressure. The plate layer is made of hard material, formed integrally on a surface of the adhesion layer. And the hook body is also made of hard material, formed integrally on a surface of the plated layer. In application, the adhesion layer is absorbed onto a smooth surface of a wall by vacuum, the super strong friction force thus produced enables the hook body to hang object of 0 112.6 kgf.

This paper proposes a robust self-organizing neural-fuzzy-control (RSONFC) scheme for a class of uncertain nonlinear multiple-input-multiple-output (MIMO) systems. We first develop a self-organizing neural-fuzzy network (SONFN) with concurrent structure and parameter learning. The fuzzy rules of SONFN are generated or pruned systematically. The proposed RSONFC scheme comprises an SONFN identifier, an uncertainty observer, and a supervisory controller. The SONFN identifier functions as the principal controller, and the uncertainty observer is designed to oversee uncertainties within the compound system. The supervisory controller combines sliding-mode control (SMC) and an adaptive bound-estimation scheme with various weights to achieve H∞ tracking performance with a desired level of attenuation. Projection-type adaptation laws of network parameters developed using the Lyapunovs synthesis approach guarantee the stability of the overall control system. Simulation studies on a single-link flexible-joint manipulator and a two-link robot demonstrate the effectiveness of the proposed control scheme. © 2006 IEEE.
