Abstract: An information collection method for an injection pen includes several steps as follows. The action of the pressing knob is sensed to determine whether the rotation information of the pressing knob is obtained. The traveling movement of the injection pen is sensed to determine whether the movement information of the injection pen is obtained. A determination is made that the traveling movement of the injection pen is conformed as an intending injection action according to the rotation information of the pressing knob and the movement information of the injection pen. When the traveling movement of the injection pen is conformed as the intending injection action, an actual injection dose that the injection content is pushed outwards from the injection pen is calculated according to the rotation information of the pressing knob. The actual injection dose is recorded.

Abstract: An acoustic echo cancellation (AEC) system includes a remote device, for capturing a remote captured sound, a server coupled to the remote device, and a local device coupled to the server. The server transmits the remote captured sound from the remote device to the local device. The local device receives, stores and plays the remote captured sound as a local playback sound. An echo is generated from reflection of the local playback sound. The local device captures the echo and a local sound into a local captured sound, and transmits both the remote captured sound and the local captured sound to the server. The server performs AEC on the local captured sound by using the remote captured sound from the local device and transmits the AEC processed local captured sound to the remote device.
