Abstract: According to certain aspects, a computer-implemented method for operating an autonomous or semi-autonomous vehicle may be provided. With the customer's permission, an identity of a vehicle operator may be identified and a vehicle operator profile may be retrieved. Operating data regarding autonomous operation features operating the vehicle may be received from vehicle-mounted sensors. When a request to disable an autonomous feature is received, a risk level for the autonomous feature is determined and compared with a driver behavior setting for the autonomous feature stored in the vehicle operator profile. Based upon the risk level comparison, the autonomous vehicle retains control of vehicle or the autonomous feature is disengaged depending upon which is the safer driver—the autonomous vehicle or the vehicle human occupant. As a result, unsafe disengagement of self-driving functionality for autonomous vehicles may be alleviated.

Abstract: A calibration array for calibrating a network analyzer, the array having multiple calibration points for direct or indirect connection to a network analyzer, and a main body connected to the calibration points, at least one of the calibration points being rotatable in relation to the main body.

Abstract: The invention relates to a calibration array (10; 50) for calibrating a network analyzer, the array having multiple calibration points (18, 20, 22, 24) for direct or indirect connection to a network analyzer, and a main body connected to said calibration points (18, 20, 22, 24), at least one of the calibration points (18, 20, 22, 24) being rotatable in relation to the main body.
