為了實現直流電源的監控，提出了一種具有USB HID數據通信功能的直流電源設計方案。詳細論述了基于STM32 USB固件庫（USB-FS Device library V3.3）的自定義HID類下位機的實現，介紹了如何在VC2010集成開發環境中編寫多線程上位機程序并運用PlotLab（一個快速信號繪圖和可視化的VCL組件）顯示實時波形，最后再以實驗開發板和PC實現了HID數據通信，證明了此監控設計方案的可行性。

1房~3房2廳，房屋裝修最重要的是電源，線材、開關質量。布局：決定以后使用的方便，比如插座多少，避免日后增加插線板。雙聯、三聯開關，可同時在不同位置開、關同一個燈，避免摸黑走路，相當方便。

Linear Technology offers a variety of devices that simplifyconverting power from a USB cable, but the LTC®3455represents the highest level of functional integration yet. The LTC3455 seamlessly manages power flowbetween an AC adapter, USB cable and Li-ion battery,while complying with USB power standards, all from a4mm × 4mm QFN package. In addtion, two high efficiencysynchronous buck converters generate low voltage railswhich most USB-powered peripherals require. TheLTC3455 also provides power-on reset signals for themicroprocessor, a Hot SwapTM output for poweringmemory cards as well as an uncommitted gain blocksuitable for use as a low-battery comparator or an LDOcontroller. The PCB real estate required for the entire USBpower control circuit and two DC/DC converters is only225mm2.

The LTC®4099 high effi ciency USB power manager andLi-Ion/Polymer battery charger seamlessly managespower distribution from multiple sources in portableapplications. It is differentiated from other USB powermanagers by its bidirectional I2C port that allows the hostmicroprocessor to control and monitor all aspects of theUSB power management and battery charging processes.In addition, a programmable interrupt generation functionalerts the host microprocessor to changes in device statusand provides unprecedented control of power managementfunctions. This high degree of confi gurability allowspost-layout changes in operation, even changes in thefi eld, and it allows a single qualifi ed device to be usedin a variety of products, thus reducing design time andeasing inventory management.

有許多老式居民房在埋設電路時大都沒有埋設電器接地線，在這樣的電路上拖接洗衣機、電熨斗、電飯煲等家用電器時，安全性極差。如果能在電路里接裝一個漏電警示插座的話，一旦電器的金屬外殼帶電便會及時發出聲、光報警信號，提醒用戶停止使用和檢修。
