Abstract: A circuit arrangement includes a preprocessing circuit configured to obtain context information related to a user location, a learning circuit configured to determine a predicted user movement based on context information related to a user location to obtain a predicted route and to determine predicted radio conditions along the predicted route, and a decision circuit configured to, based on the predicted radio conditions, identify one or more first areas expected to have a first type of radio conditions and one or more second areas expected to have a second type of radio conditions different from the first type of radio conditions and to control radio activity while traveling on the predicted route according to the one or more first areas and the one or more second areas.

Abstract: A multipoint measuring system with measuring mechanism for fast exchanging of chucking appliance and automatic material withdrawal, comprises several slide guides arranged respectively at two side plates to use the three dimensional space to build several sets of measuring components so as to meet the requirement of measuring dimensions synchronously; the measuring implement for fast changing of chucking device and easy operation has a micro adjustment set which is provided at the end of a measuring base, and the said micro adjustment set can make further suitable adjustment to the position of measuring base by means of turning the bolt rod which is arranged on the measuring probe unit, so that it will be more easy, convenient and accurate during resetting operation; an automatic material withdrawal device consists of one set of rocket arm pin and the objects to be measured can be withdrawn to the measuring position by means of the oscillation motion of the said rocker arm pin.
