• Realization of safe and worry-free community using security camera system, which watches over the whole community with privacy protection, Fujii Yusaku, Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research Grant-in-Aid for Scientific Research (B), Grant-in-Aid for Scientific Research (B), Gunma University, Apr. 2015, Mar. 2018, Principal investigator, The purpose of our research is to realize safe and worry-free community with security camera. In this study, we developed a security camera system which records all-inspection activity of the camera to prevent illegal use of the camera. With this system, it is possible to verify who, when, for what, which camera image was observed and whether the use of images was legitimate. Additionally, an image recognition function was added to the camera to greet to pedestrian and to detect illegal car stop. Some social experiments with developed cameras were carried out., Competitive research funding, No international co-authorship, 15H02887

• Laser Doppler velocimetry for dense cross-sectional velocity distribution measurement using spatial encoding and non-mechanical scanning, Maru Koichi, Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research Grant-in-Aid for Scientific Research (B), Grant-in-Aid for Scientific Research (B), Kagawa University, 01 Apr. 2015, 31 Mar. 2018, To establish a method for measuring a two-dimensional cross-sectional velocity distribution precisely and densely with a compact and reliable probe, we studied laser Doppler velocimetry using a combination of non-mechanical scanning and simultaneous multipoint measurement based on spatial encoding. We developed a technique for dense velocity distribution measurement with 48 measurement points and a signal acquisition/processing system for automated and high-speed measurement. In addition, we investigated a miniature probe using compact bulk optics and a waveguide-based integrated probe., 15H04018

• Development of an arm for care machines using dynamic behaviors and reactions of living bodies to realize safety for caregivers and care recievers, YAMAGUCHI TAKAO, Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research Grant-in-Aid for Scientific Research (C), Grant-in-Aid for Scientific Research (C), Gunma University, Apr. 2014, Mar. 2017, Coinvestigator, We investigated materials and dynamic properties for an arm in the care machines to realize safety by analyzing impact responses of the arm contacted to living bodies. We extended our nonlinear complex spring elements in FEM as nonlinear complex contact force element. Using this method, we computed motions to stop a moving object by a human finger when the block collides to the finger with his reaction. By adjusting the even terms in the imaginary parts of the nonlinear complex spring constants, we can simulate the phenomena that deformations proceed faster than the force locally in the relation between deformation and force which appear with precaution or small panic. Further, we tried to improve the performance in impact absorption for the simplified arms of care machines by referring to the bamboo swords which are used in Kendo. We obtained excellent performance in impact absorption effects by using the CFRP arms which cross sections are divided and their parts are bundled loosely., Competitive research funding, No international co-authorship, 26420167

• Suggestion of safe and secure town planning using security camera with both privacy protection and surveillance, TAKITA Akihiro; FUJII Yusaku; OHTA Naoya; UEDA Hiroshi; MARU Kouichi; YOSHIURA Noriaki, Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research Grant-in-Aid for Scientific Research (B), Grant-in-Aid for Scientific Research (B), Gunma University, Apr. 2012, Mar. 2015, Coinvestigator, In order to develop and spread the new security camera system which resolves the problem of privacy invasion, we have developed the e-JIKEI camera and have established the operating policy for this cameras system through the social experiments. As the results, the e-JIKEI door phone, which always watches at the front of its outer unit and stores the video with encryption, was developed. In the mind of residents who participates a social experiment, the sense of insecurity about privacy invading seemed to reduce and the sense of insecurity about not to be watched seemed to increase.

• Improvement of dynamic-error collection method for force transducers, FUJII Yusaku; TAKITA Akihiro; YAMAGUCHI Takao; MARU Kouichi, Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research Grant-in-Aid for Scientific Research (B), Grant-in-Aid for Scientific Research (B), Gunma University, Apr. 2012, Mar. 2015, Principal investigator, In order to improve dynamic correction method for a force sensor, we develop high-precision evaluating system of dynamic property of force sensors and evaluated and analyses the dynamic property. The measurement range and accuracy of evaluating system were improved. Some types of force sensors were evaluated and were investigated their dynamic properties by experimental results and FEM analysis. In addition to inertial, viscosity and delay of measurement equipment seemed to affect the dynamic error. We develop the correction method for the dynamic error and develop a software to correct the dynamic error with the correction method. We showed a way to resolve the problem that there is no evaluation method nor correction method for force transducers in the present state., Competitive research funding, No international co-authorship, 24360156

• Development of mechanical arms in nursing care equipments for caregivers and care recievers using dynamic properties of living bodies, YAMAGUCHI Takao; FUJII Yusaku, Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research Grant-in-Aid for Scientific Research (C), Grant-in-Aid for Scientific Research (C), Gunma University, 2011, 2013, We investigated arms in nursing machine having high shock absorbing performances. We developed calculation programs to simulate the impact properties of the arm with shock absorbers. To compute the impact responses, we proposed nonlinear complex springs that takes into account nonlinear hysteresis and the nonlinear restoring force. These nonlinear complex springs are connected to structures modeled using finite elements. We developed an evaluation device of shock absorbing performances for the arms. From the experiments and numerical analysis, we proposed a new arm with a high shock absorbing performances.The proposed arm has a core with viscoelastic foam having a hollow cross section.Under small impact forces, this arm absorbs the shock by the hysteresis damping and a buckling of the foam. This arm having the divided core includes higher shock absorbing performance due to contact friction between the divide members under large impact forces., 23560250

In this study, we developed technologies and conducted social experiments, aiming to spread the proposed concept and realize community safety. We developed various security camera systems with the function of privacy protection which enable us to significantly increase the applications of the concept, and we conducted social experiments to evaluate the systems. As the results of these activities, we have achieved the prospect of widely spreading the proposed concept., Competitive research funding, 21300268

• Improvement on tandem-type ultra-high-density multi/demultiplexer performance for use in future super-dense photonic network, TAKADA Kazumasa; FUJII Yusku, Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research Grant-in-Aid for Scientific Research (C), Grant-in-Aid for Scientific Research (C), Gunma University, 2003, 2004, Coinvestigator, Our aim was to reduce the crosstalk of primary and seconday AWGs used in a tandem-type ultra-high density multi/demultiplexer by means of photoinduced refractive index change under UV laser light through metal masks. 1.Metal mask fabrication process : We proposed a metal mask fabrication process employing an inkjet printer to draw the mask pattern and a copy machine to fix it on a resist sheet. The advantage of the method is a short fabrication process for around 10 minutes and a lower cost. 2.Phase error measurement of primary AWG : We found that an interferogram obtained from an AWG with optical low coherence interferometry is decomposed when the employed light source covers only two narrow spectral regions at two successive peaks in its AWG transmission spectrum. This was utilized successfully for measuring the phase error distribution of a 1-THz-spaced primary AWG, where the lights from 1.3 and 1.5 μm LEDs were combined to cover the spectrum with two peaks. We fabricate the metal mask for the AWG from the phase error data and succeeded in reducing the sidelobe in the spectrum by 7 dB. 3.Phase error measurement of secondary AWGs : We have succeeded in measuring the phase error distributions of narrow-channel spacing AWGs with an accuracy of 0.05 rad in the frequency domain. This was achieved by sweeping the laser frequency at 50nm/s and by removing the laser intensity noise with a balanced detection scheme. 4.Reduction of an ultra-high density tandem multi/demultiplexer : We fabricated metal masks for the secondary AWGs with the above fabrication process and succeeded in reducing the sidelobe crosstalk to -39 dB around their central arrayed waveguides. By combing them with the phase-compensated primary AWG, the accumulated crosstalk of the 1000-channel multi/demultiplexer was reduced by 5 dB as compared with the system previously reported., Competitive research funding, No international co-authorship, 15560028
