Abstract: An electronic device includes a registered jack 45 (RJ45) port, a network card, a universal asynchronous receiver/transmitter (UART), and a chip. The RJ45 port includes two receiving signal pins, two transmitting signal pins, a data transmitting pin, and a data receiving pin. The network card is connected to the two receiving signal pins and the two transmitting signal pins. The UART includes a data receiving pin and a data transmitting pin. The data transmitting pin is connected to the data receiving pin. The data receiving pin pin is connected to the data transmitting pin. The chip is connected to the UART. The UART is operable to debug or software-update the chip according to signals transmitted through the data transmitting pin and the data receiving pin.

Abstract: An automated arrangement for parsing location descriptions is provided in which semantic verification is integrated into a parsing process to reduce the generation of false results. The semantic verification involves checking up to three semantic relationships between keywords (i.e., syntactical components) parsed from the location description in a tokenization process to determine if a tokenization result is valid. The semantic relationships include: a) a spatial “part-of” relationship between location keywords; b) a spatial “near-by” relationship; and, c) a spatial “intersect” relationship. The semantic relationships between particular locations may be pre-calculated and stored as extended vocabulary to enable the semantic verification to occur early in the parsing process to thus increase overall parsing efficiency. The results of the parsing are sorted based on a rank score that is derived using the semantic relationships between the locations.
