In this paper, the wire-driven weight-compensation mechanism is proposed. This mechanism consists of a parallelogram linkage mechanism that has an extended portion with the wired double pulley. This is a lighter solution compared to others since no springs are utilized. Below, a detailed description of this new weight-compensation mechanism and performances of Float Arm V with this new mechanism are given.

In this paper, we proposed a new method of monitoring patients on bed by utilizing the facial expression analyses and recognition. In this proposed method, the optical flows of the corresponding image sequence, which appeard the facial actions, were computed. Based on the optical flow projection histogram on and coordinate axes in the mouth region and the eye region, the facial action features were extracted. By utilizing the facial action feature rate of occurrence on the happiness, easiness, uneasiness, disgust, suffering and surprise, the associate memory model of facial expressions is composed to recognize the facial expressions. The classification performance of our associate memory model is demonstrated by using a training set and a testing set from the facial expression database made for our research project.

Starting with a brief review on the single-electron memory and its significance among various single-electron devices, this paper addresses the key issues which one inevitably encounters when one tries to achieve giga-to-tera bit memory integration. Among the issues discussed are: room-temperature operation; memory-cell architecture; sensing scheme; cell-design guideline; use of nanocrystalline silicon versus lithography; array architecture; device-to-device variations; read/write error rate; and CMOS/single-electron-memory hybrid integration and its positioning among various memory architectures.
