    摘要： A method for generating r-bit parallel CRC code for a data source grouped into at least one successive p-bit parallel data group and a q-bit parallel data group is disclosed. The number q is less than the number p. The method includes the steps of: providing a data processing unit which has an output side and an input side that is adapted to receive successively the p-bit and q-bit parallel data groups, the processing unit reflecting one of the p-bit parallel data groups at the input side to the output side when the p-bit parallel data group is present at the input side, the processing unit adding a bit string to the q-bit parallel data group such that sum of the number q and number of bits in the bit string is equal to the number p, the processing unit presenting the q-bit parallel data group and the bit string at the output side when the q-bit parallel data group is present at the input side; providing a binary output generating unit which operates in response to data at the output side to produce an r-bit parallel initial CRC code according to a predefined generating polynomial function; and providing a code correcting unit which receives the r-bit parallel initial CRC code from the generating unit and which operates in response to the parallel initial CRC code to produce an r-bit parallel final CRC code according to a predefined code correcting function.

    摘要： A real-time alarm system comprises an image capturing element, a network transmission system, a control processing unit and a mobile device. The image capturing element is installed on different sites to generate image information. The image information is transmitted through the network transmission system with one end linking to the image capturing element. The control processing unit is linked to the network transmission system and includes a server, and contains preset information to compare with the image information to generate comparison information. The comparison information is analyzed by a preset algorithm to judge behaviors of objects in the images. The mobile device is linked to the control processing unit to receive the image information. After the control processing unit judges specific behaviors, it actively informs the mobile device to record a video for a selected duration to be seen anytime at a remote site.
