(Summary) 国家事業として国土全域に至る交通安全施設の高度化が進められる一方で生活道路など信号機のない交差点においては,交差点未認識などの単純な出会い頭事故が後を絶たず早急な対策が求められる.その対策として従来,路側から車両の制動距離をセンシングする技術が不可欠であったが,路面状況や車両特性及びドライバといった様々なパラメータが瞬時に変化することから移動体の挙動を推定することは困難とされていた.今回,路側からレーダにて測定可能な距離と速度の挙動指標を用いて,減速度が一定として算出していた従来の方法より精度の良い一次遅れ系モデルを提案する.本モデルは減速開始から停止するまでの時間の約25%以下の時間で誤差1m以内の精度で制動距離を推定する方法として提案する.

(Summary) Pulse Radar system and FMCW radar system have already been practically used in the society as the distance measurement systems utilizing radar beam while the industral use of them is often limited by the conditions of the Radar Transmission Regulation that stipulates mainly the allowable range of the beam intensity and the sweep band in each country. In this paper, a method to measure a short distance even in the narrow-band width is proposed and it utilizes the circuit to mix the wave reflected by the object with a transmitted wave. And also an in-phase signal and a quadrature signal of those mixed waves are utilized. As a technical reference to supprot the availability of the mehtod, a case study with RF circuit model using a diode model is presented here with showing the possible achievement of measurement error ±2mm or less in a short distance 2m or less in the simulated bandwidth of 76 MHz in 24.15 GHz band.

(Summary) Recently, data communications, e.g., animation and applications, hae demanded higher transmission speeds in the field of radio communication. To satisfy this demand, UWB-IR (ultra wide-band impulse radio) has been researched. In this communication, synchronous acquisition is neccesary to demodulate data, and sliding correlation is proposed as a basic method, but it takes a long time to resach the synchronous stage. In this research, we propose a new synchronous acquisition method that is able to greatly shorten synchronous acquisition time. In the proposed method, we divide the acquisition process in to two stages. The first stage is for finding candidate phases using power spectrum density (PSD) matching. The second stage is to acquire the phase precisely for all candidate phases using correlation. In this study, we propose a new synchronous acquisition method for UWB-IR. The proposed mehtod can signifidcantly shorten synchronous acquisition time.

(Summary) The purposes of this study were to estimate the electrical conductivity of tissues by non-invasively measuring the electrical bio-impedance, to develop a new method for tissue diagnosis, i.e., electrical impedance tomography (EIT). Tissue models were first designed taking into consideration the distribution of the fat tissue, muscle and bone in the human forearm, and then the intra-tissue distributions of electrical potential and field, and the electrical impedance in the models was theoretically analyzed by the three-dimensional finite element method. The electrical impedance of both forearms was measured in healthy human subjects, and estimated the electrical conductivity of individual local tissues. The results of the analysis showed that the distributions of electrical potential and field were affected by the presence of fat tissue but not by the presence or absence of bone. In addition, as a result of calculation of the electrical resistance of the extracellular fluid (Re) in each model, it was found that the value of bio-impedance was influenced by the presence of fat tissue, and the value of bio-impedance was increased by the intervention of a fat layer. The electrical conductivity estimated by fitting the observed values to the values obtained by finite element analysis was 0.40 S/m and 0.15 S/m for male muscle and fat tissue, and 0.35 S/m and 0.11 S/m for female muscle and fat tissue, respectively. The sex difference in the slope of linear approximation in the estimation of electrical conductivity of the males and females was thought to be due to sex differences in the properties and structure of fat tissue. These results suggest that local tissues can be diagnosed differentially and electrically by percutaneous measurement of local bio-impedance and subsequent estimation of the electrical conductivity of each tissue.

Xueli Zhao, Yohsuke Kinouchi, Emiko Yasuno, Dayong Gao, Tadamitsu Iritani, Tadaoki Morimoto and Mieko Takeuchi : A New Method for Noninvasive Measurement of Multilayer Tissue Conductivity and Structure Using Divided Electrodes, IEEE Transactions on Biomedical Engineering, Vol.51, No.2, 362-370, 2004. (Summary) This paper outlines a new method for measuring multilayer tissue conductivity and structure by using divided electrodes, in which current electrodes are divided into several parts. Our purpose is to estimate the multilayer tissue structure and the conductivity distribution in a cross section of the local tissue by using bioresistance data measured noninvasively. The effect of the new method is assessed by computer simulations using a typical two-dimensional (2-D) model. In this paper, the conductivity distribution in the model is analyzed based on a finite difference method (FDM) and a steepest descent method (SDM). Simulation results show that the conductivity values of skin, fat, and muscle layers can be estimated with an error of less than 0.1%. When random noise at various levels is added to the measured resistance values, estimates of the conductivity values for skin, fat, and muscle layers are still reasonably precise: their root mean square errors are about 1.06%, 1.39%, and 1.61% for 10% noise. In a 2-D model, increasing the number of divided electrodes permits simultaneous estimates of tissue structure and conductivity distribution. Optimal configuration for divided electrodes is examined in terms of dividing pattern.

(Summary) To estimate inner multi-layer tissue conductivity distribution in a cross section of the local tissue by using bioresistance data measured noninvasively on the surface of the tissue, a measurement method using divided electrodes is proposed, where a current electrode is divided into several parts. The method is evaluated by computer simulations using a three-dimension (3D) model and two two-dimension (2D) models. In this paper, conductivity distributions of the simplified (2D) model are analyzed based on a combination of a finite difference method (FDM) and a steepest descent method (SDM). Simulation results show that conductivity values for skin, fat and muscle layers can be estimated with an error less than 0.1%. Even though different strength random noise is added to measured resistance values, the conductivities are estimated with reasonable precise, e.g., the average error is about 4.25% for 10% noise. The configuration of the divided electrodes are examined in terms of dividing pattern and the size of surrounding guard electrodes to confine and control the input currents from the divided electrodes within a cross sectional area in the tissue.

(Summary) The purpose of this study was to evaluate the possibility of differential diagnosis of tumors, such as breast cancer, by measuring the mammary electrical bioimpedance via the skin surface noninvasively and by examining the relationship between the tissue structure of the breast and electrical bioimpedance. The mammary electrical bioimpedance was measured in 24 patients with breast cancer. Taking into account the measurement results and the distribution of the mammary glands and fatty tissue, a breast model with tumors was proposed. Based on this model, the distributions of the electric potential and electric field in the tissue were theoretically analyzed by the three-dimensional finite element method. In clinical cases, the Re values of the diseased breast were significantly larger than those of the contralateral healthy breast. In theoretical analysis based on the breast model, the Re value of mammary electrical bioimpedance varied due to the structure of the breast, that is, the ratio of fatty tissue to mammary gland and the presence of mammary tumors. The results of the measurement agreed with the theoretical analyses. These results suggest that differential diagnosis of breast tumors is possible by measuring the mammary electrical bioimpedance using noninvasive electrodes on the skin.

(Summary) A new system of impedance measurement over a frequency range of 0 to 200 kHz was developed by a three-electrode method. In this study, the electrical impedances of various tumors were measured in vivo in 54 patients with breast disease (31 breast cancers, 13 fibroadenomas, and 10 fibrocystic diseases) and 57 patients with pulmonary disease (44 lung cancers, 5 metastatic pulmonary tumors, 4 pulmonary tuberculoses, and 4 organized pneumonias). On the basis of those impedance measurements and the equivalent circuits in vivo, we calculated the extracellular resistance (Re), intracellular fluid resistance (Ri), and cell membrane capacitance (Cm) in tissues, all of which were compared among the various diseases. It was found that Re and Ri were significantly higher in breast cancers than in benign tumors and normal breast tissues and that Cm was significantly lower in breast cancers than in other tissues. On the other hand, Re and Ri were significantly higher, and Cm was significantly lower, in normal lung tissues than in pulmonary masses. Re and Ri were significantly higher, and Cm was significantly lower, in malignant tumors than in organized pneumonias. The results showed that these parameters (Re, Ri, and Cm) exhibit significant differences among various tissues and tumors, suggesting possible applications in tumor diagnosis.

(Summary) Blood flow velocity in the common carotid artery and the electrocardiogram were measured simultaneously by telemetry in seven male subjects during 20-min walking on a treadmill at an exercise intensity corresponding to a mean oxygen uptake of 26.0 (SD 2.9) ml.kg-1.min-1. The mean cardiac cycle was shortened from 0.814 (SD 0.103) s to 0.452 (SD 0.054) s during this exercise. Of this shortening, 73% was due to shortening of the diastolic period and 27% to shortening of the systolic period. In the relatively small shortening of the mean systolic period [from 0.377 (SD 0.043) s to 0.268 (SD 0.029) s], the isovolumetric contraction time was shortened by 56%. During exercise, the heart rate (fc) increased by 79.4% [from 74.3 (SD 9.3) beats.min-1 to 133.3 (SD 14.8) beats.min-1], and the peak blood velocity (S1) in the common carotid artery increased by 56.1% [from 0.82 (SD 0.10) m.s-1 to 1.28 (SD 0.11) m.s-1]. After exercise, the S1 decreased rapidly to the resting level. The fc decreased more slowly, still being higher than the initial resting level 5 min after exercise. The diastolic velocity wave and the end-diastolic foot decreased during exercise. The blood flow rate in the carotid artery increased transiently by 13.5% at the beginning of exercise [from 5.62 (SD 0.63) ml.s-1 to 6.38 (SD 0.85) ml.s-1] and by 26.5% at the end of the exercise period [from 5.62 (SD 0.63) ml.s-1 to 7.11 (SD 1.34) ml.s-1].(ABSTRACT TRUNCATED AT 250 WORDS) (Keyword) Adult / Blood Pressure / Carotid Artery, Common / Electrocardiography / Exercise / Exercise Test / Heart Rate / Humans / Male / Oxygen Consumption / Regional Blood Flow / Time Factors / Walking (Link to Publication Site) ● Publication site (DOI): 10.1007/BF00241643 (Link to Search Site for Scientific Articles) ● PubMed @ National Institutes of Health, US National Library of Medicine (PMID): 8149926 ● Summary page in Scopus @ Elsevier: 2-s2.0-0027729117 (DOI: 10.1007/BF00241643, PubMed: 8149926, Elsevier: Scopus)

(Summary) 従来の時間領域の現象に基づく周波数変調レーダ等は，その測定原理により近距離の測定が困難である．本研究では定在波を利用した近距離レーダを提案し， 0.4mからの測距および，複数ターゲット化を実現している．定在波の振幅は周波数に対し，周期的に変化する特徴から，フーリエ変換を用いてこの周期性を求め，距離検出を行う．実際にはFFTを使用することから，ピークのスペクトルが広がるため，分離分解能の限界がある．そのため，FFT処理後に位相補正を行った測距方式では， 300ppmの分離分解能を実現している．本稿では，分離分解能の向上を目的とし，その一手法としてMUSIC法を適用した測距方式を提案する．

(Summary) サンプルホールド型位相比較周波数シンセイサイザは，ループにローパスフィルタを含まないことから，1次の周波数収束が可能である．更に基本(リファレンス)周波数を高くすることで，基本周波数に比例した速さで周波数収束が可能である．しかし，合成可能な出力周波数の間隔が基本周波数に等しくなるという制約があり，出力周波数の分解能が荒くなる．本稿では，基本周波数を高くしたときに，特定の規則で分周比を変化させ，連続する2つの位相差から目的周波数に対応する位相差を補間することで，出力周波数間隔を保ったまま，高速な周波数切換えが可能なシンセサイザを提案する．また，数値シミュレーションにより，基本周波数に比例した速さで収束が可能であることを示す．
