The NODE+ has dimmable blue LEDs and two module ports contains a crypto chip on the firmware. It communicates with Bluetooth 2.1 or Bluetooth Low Energy. The lithium polymer battery in the device has a battery life of 12–14 hours with continuous Bluetooth use (54 days in standby mode) and can be charged through the micro-USB port. [22]
The USB HID class describes devices used with nearly every modern computer. Many predefined functions exist in the USB HID class. These functions allow hardware manufacturers to design a product to USB HID class specifications and expect it to work with any software that also meets these specifications. The same HID protocol is used unmodified ...
ELM327. The ELM327 is a programmed microcontroller produced for translating the on-board diagnostics (OBD) interface found in most modern cars. The ELM327 command protocol is one of the most popular PC-to-OBD interface standards and is also implemented by other vendors. The original ELM327 was implemented on the PIC18F2480 microcontroller from ...
3D scanning. Making a 3D-model of a Viking belt buckle using a hand held VIUscan 3D laser scanner. 3D scanning is the process of analyzing a real-world object or environment to collect three dimensional data of its shape and possibly its appearance (e.g. color). The collected data can then be used to construct digital 3D models .
Google's mobile Android operating system can use their own Google Lens application to scan QR codes, or third-party apps like Barcode Scanner to read both one-dimensional barcodes and QR codes. Google's Pixel devices can natively read QR codes inside the default Pixel Camera app. Nokia's Symbian operating system featured a barcode scanner, [ 28 ...
These are the items Americans lose most. Perhaps unsurprisingly, the most commonly lost items were also among the most ubiquitous and important: phones and keys. Most people don't leave home ...
Calculator input methods. There are various ways in which calculators interpret keystrokes. These can be categorized into two main types: On a single-step or immediate-execution calculator, the user presses a key for each operation, calculating all the intermediate results, before the final value is shown.
