Abstract: This application is directed to a geographic information display method. While a first mobile device is executing an instant messaging application, it obtains its own geographic location information, a second mobile device's geographic location information, and a first timestamp at which the geographic location information is recorded. The first mobile device then displays an interactive map associated with the first timestamp on a user interface. The displayed map includes two marks that represent the locations of the first and second mobile devices, respectively, and instant messages exchanged between these two mobile devices are displayed on the map adjacent to the two marks. As the first mobile device obtains updated geographic location information in association with a second timestamp, it updates the location of the second mobile device while the mark corresponding to the first mobile device remains at the same location on the user interface.

Abstract: A single-photon detector is provided. The detector has multiple avalanche layers. It has an avalanche photodiode (APD) structure using single photon. The APD is made of indium aluminum arsenide (InAlAs). At least two avalanche layers are designed. When the layer for avalanche is numbered only one and the gain is very big, the speed will be deteriorated very quickly. With the design of two avalanche layers in the present invention for the very big gain, the speed deterioration can be suppressed. After measuring, the present invention shows a faster speed as compared to prior arts. It proves that, by using more than two avalanche layers, the present invention effectively improves the feature of single-photon detector. Hence, the present invention is especially suitable for single-photon detection.
