Abstract: A method for finding a parked vehicle is disclosed. A moving vehicle executing the method broadcasts packets with an identifier of the vehicle and a time stamp. Other neighboring vehicles surrounding the moving vehicle records content of the packets. The moving vehicle is then parked. A key of the parked vehicle is operable to issue a search request with the identifier to the neighboring vehicles. The neighboring vehicles allocate time frames for relaying the search request with respect to the time stamp. Upon receiving the search request, the parked vehicle replies with a search response along the neighboring vehicles to the key set.

Abstract: A method for locating a vehicle left parked in a parking lot can be applied by an electronic device in the hands of the driver. The method generates a first data package based on the vehicle and the same is broadcast to other vehicles in the parking lot as a parking space is being found. A second data package is generated when the driver takes his electronic device away from the parked vehicle and sent to the other vehicles within a preset range. Upon the driver's return, the parked vehicle can generate a navigation path to itself. The navigation path sent by the parked vehicle is received by the electronic device, and the electronic device can prompt a driver to locate his/her own parked vehicle according to information of the navigation path.

Abstract: A method executed by a conference terminal for processing videos from other conference terminals includes the following steps. Capture a video in front of the video camera. Extracting sub-images of the projection screen and the indicator from each video frame. Determining a size of the sub-image of the projection screen and size of the sub-image of the indicator. Determining distances between one fixed spot of the indicator and two reference spots of the projection screen in each video frame. Receiving from each other conference terminal the sub-image of the indicator, the sizes of the sub-images of the indicator and the projection screen, and the distances. Scaling the sub-image of each indicator from each of the other conference terminals and the distances from each other conference terminals. And positioning each scaled sub-image of the indicator to the projection screen according to the scaled distances to obtain a combined image.
