Implementation of Lightweight eHealth Applications on a Low-Power Embedded Processor

Abstract: The rapid development of Internet of Things (IoT) has opened new opportunities for healthcare systems through so-called eHealth systems. With the help of monitoring using portable IoT devices with biomedical sensors, disease diagnoses can be conducted in real time. However, there is a challenge in that monitoring is an always-on activity that requires constant power supply and IoT devices are battery-powered and face heavy resource constraints. This work addresses a realistic implementation of a low-power eHealth device using both hardware and software approaches …

watchOS 7.3配信開始。日本でも心電図アプリと不規則な心拍通知機能が利用可能に


アップルは26日(米現地時間)、watchOS 7.3の配信を開始しました。かねてからの予告通り日本でも心電図(ECG)アプリが提供開始され、不規則な心拍通知機能(IRN、irregular heart rhythm notification)も実装されました。

watchOS 7.3は、iPhoneのWatchアプリを通じて無料でダウンロードできます。新たなソフトウェアをインストールするためには、まずiPhoneを最新バージョンのiOS(記事執筆時点ではiOS 14.4)にアップデートすることが必要です。そしてApple Watchが50%以上充電されていることを確認し、通信範囲に収まるようiPhoneの近くに置きます。

最新のアップデートでは、まずApple Watch Series 4以降にてECGアプリが日本でも利用可能となりました。ECGアプリは昨年(2020年)9月に国内で医療機器として承認を受けていましたが、それから4ヶ月越しの実現となります。

Set up Home Assistant to manage your open source smart home

Learn how to install and configure Home Assistant in the fourth article in this series on home automation.

In the first article in this series, I introduced Home Assistant and why you might be interested in it. In short, Home Assistant is an automation hub for some of the most common smart devices on the market today. It enables centralized coordination of disparate hardware. By using it, you no longer have to choose suboptimal tech from a single vendor to manage your smart home from a single app. It also means you will no longer struggle with a hundred different apps that all function slightly differently to manage all your devices. One program to rule them all… or at least that’s the dream.

In the second and third articles, I looked at some of the decisions to make when developing home automation, namely local vs. cloud control, and whether to choose Zigbee, Z-Wave, or WiFi, just to hit the high points. This fourth article will be much more hands-on than the previous ones by walking you through setting up a virtual machine (VM) with the Home Assistant-provided image.

Set up the VM

I won’t cover all of the methods available for installing Home Assistant (HA). I run HA in a virtualized environment, and the official installation page provides VMDK, VHDX, VDI, QCOW2, and OVA downloads. I have a libvirt-based homelab, so I chose the QCOW2 image…
