This is a repository of relevant industrial standards for quick references by consumers. The objective is to extract, re-organize and store standard technical information that may be helpful to buyers of products.
The lack of knowledge is a common problem for everyone, esp. for a technical buy. It is not surprising to find buyers who is unaware of the current standards or technology as they do not follow closely to recent developments. The questions could be related to a new technical specifications, policy or protocol.
- What is USB 4 and or QC 3.0, and how do they affect him?
- Does the specification meet his intended usage?
We have consolidated some standards which we hope will be useful for quick reference.
- Quick Charge Reference
Quick Charge (QC) is a proprietary battery charging protocol developed by Qualcomm. It is used for managing power delivered over USB, mainly by communicating to the power supply and negotiating a voltage of mobile devices.
- USB Standards for Charging and Data Transfer
USB standard is maintained by the USB Implementers Forum (USB-IF), and their official website is at USB.org. The founding companies of USB-IF were Compaq, Digital, IBM, Intel, Microsoft, NEC and Nortel. Currently, notable members include HP, NEC, Microsoft, Apple Inc., Intel, and Agere Systems.
- Digital Camera Sensor Size Chart
Many camera or phone design focuses on Mega Pixel specifications, i.e. MP. However, it is the camera sensor size that affects the quality of the image. A bigger sensor will capture more lights, and should produce a higher quality photo than a smaller sensor. Manufacturers are beginning to focus on bigger sensors, and so should buyers.
