Technical Note—Slowdown in the Energy Efficiency of Analog-to-Digital Converters and a Compressed-Sensing-Based Solution
Full text linkPower consumption remains a critical bottleneck in the design of sensor systems. To investigate power consumption problems in sensor circuits, we surveyed the latest developments in analog-to-digital converter (ADC) integrated circuits, which are indispensable components of sensor front ends. An evaluation based on the Walden figure-of-merit, using data from ADCs presented at the International Solid-State Circuits Conference, revealed a slowdown in the energy-efficiency improvement of state-of-the-art ADCs. To overcome this limitation, we are developing a compressed-sensing-based solution: a lowpower sensing approach that combines random undersampling with compressed-sensing reconstruction. A prototype wireless electroencephalogram system implemented on a general-purpose microcontroller reduces both sampling activity and radio duty cycle, achieving continuous operation at 72 μWwhile maintaining signal fidelity. These efforts are expected to pave the way for next-generation ultralow-power and energy-harvesting sensor networks

A demographic and nutritional analysis of urban lower-class dwellers in modern Japan revised version: the case of one Saimin-chiku in Tokyo, ca.1930
No full text* Revised：Kenichi Tomobe, Minori Oshidari, Keisuke Moriya [22-06, 2022]This study aims at investigating a method to measure the standard of living, nutritional status, and physical condition of the saimin (“the poor") who suddenly appeared in the modern age and settled there despite their poverty. In the study of social science, the mainstream theories of poverty are Charles James Booth's stratification theory based on income level and Benjamin Seebohm Rowntree's minimum cost of living theory based on the cost of living; both have their merits and demerits. This paper will measure the poverty levels in terms of income and cost of living using data from a specified sub-district located in Tokyo (the results of an on-site survey of approximately 180 households). Many households living in the Saimin-chiku faced poverty both income levels and cost of living. In addition, observation of the health status of the saimin households showed that roughly half of the community had a disease of some sort, or a tuberculosis patient in the household. This provides a perspective which illuminates the difference in situation between the saimin households, who made a living based on an economy of mutual support, and the small farmer households, who had a communal consumption lifestyle but had the capacity to be self-supporting
