Abstract: A method and system for managing overlapping windows on a computer screen of a computer system. A hook filter intercepts an event that has occurred. An association of the hook filter with the event was established prior to the occurrence of the event. The event is characterized by an overlapping condition in which a floating window partially or totally overlaps an active window on the computer screen. A software application is associated with the active window. Response to intercepting the event, the hook filter detects the overlapping condition. Response to detecting the overlapping condition, the hook filter eliminates the overlapping condition to make the active window totally visible.

Abstract: An approach for generating optimal itineraries based on network connectivity is presented. A computer receives a first message from which a current position of a vehicle on a trip, destination, a service being requested for a mobile device in the vehicle, service providers and network(s) are extracted. Network connectivity measures are retrieved and signal qualities in respective cells are determined based on the network connectivity measures. Based on the signal qualities, an itinerary is determined as paths and a hop indicating a position on one of the paths at which a connectivity change from a first to a second service provider is to occur. A response to the first message indicates the itinerary. Sending the response results in the mobile device making the connectivity change when the vehicle reaches the position indicated by the hop.

Abstract: An approach for generating optimal itineraries is presented. As a response to a first message sent to a remote computer system by a global positioning device transported by a vehicle on a trip, the device receives a second message indicating optimal itineraries of the trip. The device receives a selection of an optimal itinerary indicating a path, a hop, an updated service provider to provide a service to a mobile device transported by the vehicle, and an updated network for providing the service. The device detects the vehicle at a position indicated by the hop, and in response, generates a third message indicating the updated service provider and the updated network. The global positioning device sends the third message to the mobile device and as a result, the mobile device makes a connectivity change to the updated service provider and/or to the updated network.

Abstract: An approach is provided for collaboratively synchronizing devices in an ad hoc network. No device is acting as a master device or base station dictating time slot allocation to devices. A first device communicates with the other devices by a Media Access Control scheme based on time frames having time slots. Responsive to a determination that a current time slot allocated to a second device is occurring, a determination that a Boolean value selected according to a predetermined probability is true, and a transmission of a map of allocations of time slots to the devices, the first device determines the map indicates a conflict in which the same time slot is allocated to the first device and another device. The first device resolves the conflict by allocating another time slot to the first device, so that each time slot is allocated to no more than one corresponding device.
