Abstract: A motion control servo loop apparatus, comprising: a feed-forward control module, and a proportional-integral-derivative (PID) control loop and a compensation adder. The feed-forward control module is capable of generating a feed-forward compensation. The PID control loop further comprises: a proportional control module, an integral control module and a derivative control module. The proportional control module is capable of generating a proportional compensation. The derivative control module is capable of generating a derivative compensation. The integral control module uses a digital differential analyzer (DDA) algorithm to perform integration for accumulated errors with respect to each sampling clock at each DDA pulse and thus output an accumulated error, which is then processed to generate an integral compensation.

Abstract: A card edge connector for mating with an electronic card includes an elongated housing, a number of contacts and a retainer retained to the housing. The housing has a pair of side walls, a central slot between the side walls and a fitting section upwardly extending at one end thereof.

Abstract: An adaptive real-time analysis method for dynamic signals generated by rotary machines improves Vold-Kalman filtering order tracing technology to renew the algorithm logic so that on-line computation ability is achieved. Through signal simulation and practical engineering application to verify the availability, it shows that the output results are extremely accurate. As such, this method is advantaged to estimate the time-domain waveform of specific order signals for the operation of the rotary machines and to interpret the related physical phenomena. Moreover, this method can be applied for a digital signal processor (DSP) to obtain real-time and on-line computation of the order signals needed to be traced and to display the tracing time-domain waveform instantly.

Abstract: All in one multifunction pallet, comprising a main part of the pallet, collapsible supporting legs, belts, joint shafts coupled by nuts, and RFID tags providing an easy to use, easy to operate and easy to recycle pallet. RFID tags equipped on the pallet offer a great advantage for supply chain management to utilize RFID technology. The fully folded pallet has zero space waste and one truck can transport at least fourfold pallets comparing with the currently and widely used and various pallets existing on the market. This convenient to use, recyclable, all in one pallet can significantly lower various RFID tag costs in RFID technology applications in large scale. Any damaged part can be easily replaced with new parts to keep the pallet continually in use, thereby reducing the coast per pallet in the supply chain.
