We have investigated the pressure dependence of the detection sensitivity of CO(2), N(2)O and CH(4) using wavelength modulation spectroscopy (WMS) with distributed feed-back diode lasers in the near infrared region. The spectral line shapes and the background noise of the second harmonics (2f) detection of the WMS were analyzed theoretically. We determined(More)
In this paper, we propose a voice-controlled electric wheelchair with a system for detecting the position and direction. Thus far, we have studied systems that incorporated voice instructions with our indoor navigation equipment using RF tags. An operating method which is different in order to clarify the problem of the operation method of an existing(More)
PURPOSE Quantitative imaging of neuromagnetic fields based on automated region of interest (ROI) setting was analyzed to determine the characteristics of cerebral neural activity in ischemic areas. METHODS Magnetoencephalography (MEG) was used to evaluate spontaneous neuromagnetic fields in the ischemic areas of 37 patients with unilateral internal(More)
We report pharmacokinetics, efficacy and safety data for a new 150-mg alectinib capsule in ALK+ non-small-cell lung cancer in a multicenter, open-label pharmacologic study (JP28927). Eligible patients (≥20 years, locally advanced/metastatic ALK+ disease, ALK inhibitor-naïve and -pretreated [including crizotinib refractory]) were randomized 1:1 to receive(More)
This paper provides a study on a supporting system of chorus singing for visually impaired persons. This system is composed of an electric music baton with an acceleration sensor, a radio module, haptic interface devices with vibration motors, depth image sensor and a PC. An electric music baton transmits a signal of a conductor's motion to visually(More)
