For reducing a risk of pressure sore caused by long period sitting on a wheelchair, a patient is required to depressurize buttocks by changing the posture suitably. Thus, we have been developed an automatic depressurization motion assistance system for a seated patient on a wheelchair. In our previous work, we developed a sitting surface coordination system which can lift or incline and assists a depressurization motion of a patient. However, in some cases, it is difficult to change his posture suitably for patients who do not have enough physical strength in their upper body using our proposed device. Therefore, in this paper, we propose a novel posture coordination assistance system for a wheelchair user. Our system consists of the adjustable sitting surface and novel proposed adjustable backrest. These two devices coordinate the sitting posture of the patient automatically. Our key ideas are two topics. One topic is mechanical design of the adjustable backrest for practical use. We realize small mechanism which enables easy implementation to a general wheelchair without special reconstruction. The other topic is a natural posture coordination scheme using the sitting surface and the backrest. We analyze buttocks depressurization operation by a nursing specialist and drive our proposed devices for realizing it. The performance of our system is verified by experiments using our prototype.

Regulation of the Cyanobacterial Circadian Clock by Electrochemically Controlled Extracellular Electron Transfer†

引用

Angewandte Chemie 2014年第8期126卷

There is growing awareness that circadian clocks are closely related to the intracellular redox state across a range of species. As the redox state is determined by the exchange of the redox species, electrochemically controlled extracellular electron transfer (EC‐EET), a process in which intracellular electrons are exchanged with extracellular electrodes, is a promising approach for the external regulation of circadian clocks. Herein, we discuss whether the circadian clock can be regulated by EC‐EET using the cyanobacterium Synechococcus elongatus PCC7942 as a model system. In vivo monitoring of chlorophyll fluorescence revealed that the redox state of the plastoquionone pool could be controlled with EC‐EET by simply changing the electrode potential. As a result, the endogenous circadian clock of S. elongatus cells was successfully entrained through periodically modulated EC‐EET by emulating the natural light/dark cycle, even under constant illumination conditions. This is the first example of regulating the biological clock by electrochemistry.

This paper propose a dynamic personal space which is a region surrounding a person who can feel comfortable psychologically to other person with a personal mobility vehicle in the pedestrian flows. A dynamic personal space is defined considering with a relative velocity and acceleration between them. Therefore, it changes dynamically according to the advance velocity and acceleration of the personal mobility vehicle. Using this idea, a personal mobility vehicle will be able to move in a human coexistence environment without a feeling of oppression on other people. In this paper, we investigate spatial relationship with a personal mobility vehicle experimentally and define a dynamic personal space using these results. For verifying its effectiveness, we implement a drive assistance algorithm, which avoids a dynamic personal space, to our prototype personal mobility vehicle.

Superconductivity induced by electron doping in La1−xMxOBiS2 (M= Ti, Zr, Hf, Th)

We report a strategy to induce superconductivity in the BiS2-based compound LaOBiS2. Instead of substituting F for O, we increase the charge-carrier density (electron dope) via substitution of tetravalent Th+4, Hf+4, Zr+4, and Ti+4 for trivalent La+3. It is found that both the LaOBiS2 and ThOBiS2 parent compounds are bad metals and that superconductivity is induced by electron doping with Tc values of up to 2.85 K. The superconducting and normal states were characterized by electrical resistivity, magnetic susceptibility, and heat capacity measurements. We also demonstrate that reducing the charge-carrier density (hole doping) via substitution of divalent Sr+2 for La+3 does not induce superconductivity.

In this paper, the effect of adding porous Cu to Sn-based solder on the joint strength of the solder alloy was investigated. The porous Cu was arranged in a sandwich-liked layer with Sn-based solder alloys. The soldering process involved different soldering temperature and time. Shear test was also performed to evaluate the joint strength of the solder alloy for both with and without addition of porous Cu. Preliminary results showed that the shear strength increased proportionately with increasing soldering temperature and time. In addition, the shear tests on soldered sample with porous Cu showed an increase in joint strength compared to soldered sample without porous Cu. This result showed that porous Cu has influence on the shear strength of the soldered sample. The follow up investigation was conducted to analyse interfacial reaction that occurred at the solder joints. Details on deformation of intermetallic compound was observed by using optical microscopy (OM). Photo images showed that porous Cu reacted with molten solder paste and were diffused at the boundary of the solder alloys. © 2012 IEEE.

Since the structure and D.O.F. of human and machine are different, the motion of human and machine is essentially different. This study defines "Pseudo Human Motion" as approximated machine's motions referring to the standard human motion. If the pseudo human motion is realized, the operation of complex machine becomes easy, because the motion of complex machine becomes human-like motion. In order to realize pseudo human motion, we derive the standard human motion which is to be a model for the machine's motion. For this purpose, we measured the human motions of plural subjects by using motion capture system. The human motion is different in each subject about the motion time, therefore it is difficult to directly use measured human motion as a standard human motion. We adopts following solutions for this problem. The fundamental components of each subject are extracted from measured human motion data by using DFT(Discrete Fourier Transform). And the fundamental components are plotted on the phase plane. There are no big differences among the human motion of each subject on the phase plane. Thus we do ellipse fitting to the each subject motion on the phase plane, and we call it the standard human motion. This ellipse trajectory, which is standard human motion, can evaluate motions even if different motion in time domain, and can absorb different motion cycle and amplitude caused by individual physical characteristics and peculiarities.
