The equipment room should be strong enough to resist winds and downpours. The room should be located away from dusty roads or sand. If this is unavoidable, the doors and windows of the equipment room must not face pollution sources. Do not place air conditioning vents near the equipment so...
to collect the data locally or send them to an external device. In both cases, the data should be encrypted to enforce their privacy. Given that wearable devices usually have low computational power, a lightweightauthenticationtest is needed. In addition, wearable devices must be able to ...
After constructing the device, we then sought to test its performance in generating water at low RH via an active mode of operation. An active water harvesting cycle (WHC) was defined as follows: 40 min adsorption phase (an adsorption phase is defined as simply pulling air by the fan fro...
Business Justification In order to test Time-To-Fix performance characteristics of a GPS device e.g. whether A-GPS is supported or Time-To-First-Fix after a cold start , it is needed to instruct the driver to clear the assistance data. Since there is no user scenario for apps to clear...
Two Beijing schools have installed equipment that allows them to measure campus air quality in real-time, in an effort to prevent the spread of airborne illnesses and determine if children should play outside. If the one-year trail period is successful it will be applied to all Beijing schools...
