In this study, polyethylene (PE) battery membranes without any\nhydrophilic modification were directly used to prepare PE-RO membranes. The structures of the\nproducts were confirmed via attenuated total reflection Fourier transform infrared spectroscopy,\nX-ray photoelectron spectroscopy, and scanning ...
3 Low-Cost Development Tools Guide Mixed Signal Products MCP3421 Battery Fuel Gauge Demo Board Part Number: MCP3421DM-BFG NEW This board is used to demonstrate the MCP3421 18-bit delta-sigma ADC for battery fuel gauging applications. It includes two MCP3421 devices, MCP73831 (single cell Li...
Live images of the F4 have surfaced, showing that the rear camera will be upgraded to a 64MP main sensor (up from 48MP on the K40S). The rest is expected to be the same, including the 6.67” AMOLED display with FHD+ resolution and 120Hz refresh rate, plus 1,300nits p...
It is also modular, with the ability to replace individual components and maintain functionality without changes to form or software. For example, given the use of generic GPIO-based trigger of the relay control board, the Raspberry Pi could be swapped with other embedded computers such as the ...
The main challenge of the renewable energy systems is their dependence on some factors, which are difficult to control; one of these factors is the climatic conditions. The hybrid storage technology (combination of supercapacitor and battery) is very useful for storing and controlling power, and ...
This mechanism is responsible for moving the most-charged battery to the required position such that it can replace the current battery. It should be noted that the system can only work with three batteries: two charged and one within the quadrotor. Furthermore, it is important to mention ...
You lose the extension interface, but gain an infrared communication port that lets you talk to other PTC-300s). One reason for the weight loss is that the device now uses a smaller, less widespread battery (which also can be replaced by 2 AA batteries in a holder). The PTC-300 has ...
