Abstract: The present disclosure relates to a multi-touch method, configured to a touch panel. The method comprises: applying a first object to touch a first image on the touch panel for inputting a first password; and determining whether inputting a second password, and if not, removing the first object from the touch panel for ending a first round of password input.

Abstract: A receiver of a communication system includes: an input module, a group-based pre-decoding module and a reconstructing module. The input module is for receiving a received data. The group-based pre-decoding module is for combining the received data with a grouped decoding matrix into an encoded equation matrix (EEM) based on a group parameter and for performing a group operation on the EEM. The reconstructing module is for reconstructing the EEM obtained from the group operation into an output data.

Abstract: In one exemplary embodiment of an apparatus for accelerating the encoding of Raptor codes, based on an inputted block length, a pre-encoding matrix generation device determines to generate an encoding matrix M corresponding to the inputted block length and computes an inverse matrix M?1, or makes a pre-coding operation list storage device output an operation list corresponding to the inputted block length; based on the encoding matrix or the inverse matrix M?1, a pre-encoding operation list generation device generates a new operation list; based on one of the aforementioned two operation lists and an inputted source symbol set, at least one prompt intermediate symbol generation device generates at least one intermediate symbol set to provide to a fountain code encoder for encoding.
