A computer implemented method and system for managing events scheduled by multiple users in a group, provides an event management platform (EMP) in communication with a client application on each user's computing device via a network. The EMP acquires characteristic information on each computing device and each user's third party calendar applications (TPCAs), and event information on the events. The EMP, in communication with the client application, generates and stores the events based on the event information. The EMP stores the events across a data store residing on each computing device external to the client application and/or the data stores of the TPCAs, using the acquired characteristic information and event information. The stored events are accessible to each user associated with the events for performing one or more actions that are tracked and automatically updated by the EMP. The EMP also notifies the availability of the users in the group.

A vehicle travels along a road with its lights on because of the conditions outside the vehicle. It has an onboard optical sensor associated with the headlights and arranged to form an image of a zone of the road in front of the vehicle, so that the state of humidity of the road can be determined, and the light output modified accordingly. The zone concerned, on the road, consists of at least one segment oriented in the direction of travel, so that the image created by the optical sensor is a characteristic curve representing the light distribution on the road. This image is compared with a reference curve to determine the state of humidity. The reference curve represents light distribution when the road is dry.

After a vehicle has entered a curve, a deviation (Sch) between a target turning state quantity Td and an actual turning state quantity Ta is computed. In a stage in which Sch does not reach a predetermined value after the vehicle has entered the curve, the possibility of the vehicle traveling in the curve is judged to be low, and the reliability of the curve information Rc, Pc is judged to be low. In this case, a determination for prohibiting execution of control (So=0) is made. In a stage after Sch has reached the predetermined value, the possibility of the vehicle traveling in the curve is judged to be high, and the reliability of the curve information Rc, Pc is judged to be high. In this case, a determination for permitting execution of the control (So=1) is made. Deceleration control is started and executed only when a control start condition is satisfied, and the determination for permission is made. Accordingly, even when the control start condition is satisfied, the deceleration control is not started, if the prohibition determination is made. Thus, the reliability of the curve information based on map information on the vehicle is evaluated reliably, and the deceleration control within the curve can be prevented from being unnecessarily executed on the basis of curve information whose reliability is low.

A method and a device for monitoring the intake manifold pressure of an internal combustion engine in which a measured signal for the intake manifold pressure is compared with a reference signal for the intake manifold pressure. For a deviation of the measured signal for the intake manifold pressure from the reference signal for the intake manifold pressure, a tolerance range is predefined for error-free operation of the intake and/or exhaust valves of at least one cylinder of the internal combustion engine. A check is made whether the measured signal for the intake manifold pressure deviates from the reference signal for the intake manifold pressure by more than a predefined tolerance range. In this case an erroneous operation of the intake and/or exhaust valves is detected; otherwise an error-free operation of the intake and/or exhaust valves is detected.

In sophisticated semiconductor devices including copper-based metallization systems, a substantially aluminum-free bump structure in device regions and a substantially aluminum-free wire bond structure in test regions may be formed on the basis of a manufacturing process resulting in identical final dielectric layer stacks in these device areas. Moreover, reliable wire bond connections may be obtained by providing a protection layer, such as an oxide layer, after exposing the respective contact metal, such as copper, nickel and the like, thereby providing highly uniform process conditions during the subsequent wire bonding process. The number of process steps may be reduced by making a decision as to whether a substrate is to become a product substrate or test substrate for estimating the reliability of actual semiconductor devices. For example, nickel contact elements may be formed above copper-based contact areas wherein the nickel may provide a base for wire bonding or forming a bump material thereon.
