Abstract: An electrical connection apparatus includes a cable connector, a PCB, and a fastened wall. The cable connector includes a connecting terminal and a plurality of first contacts. One part of each first contact is located in the connecting terminal, and the other part extends from the connecting terminal. The printed circuit board includes a substrate and a plurality of second contacts. The plurality of second contacts are located on a surface of the substrate. The fastened wall includes a plurality of sidewalls. The plurality of sidewalls are fastened to the substrate, and are located on at least two opposite sides of the plurality of second contacts. When the cable connector and the PCB are fitted, the cable connector and the fastened wall are detachably fastened, and the first contact and the second contact are in close contact.

Abstract: A computer-implemented method for detecting character encodings of text streams may include 1) identifying a request to identify a character encoding of a text stream, 2) dividing the text stream to identify a plurality of n-grams within the text stream, 3) identifying a plurality of vectors within a vector space, each vector representing a potential character encoding by a plurality of expected n-grams within the potential character encoding, 4) generating, based on the plurality of n-grams within the text stream and on an inverse frequency of appearance of each of the plurality of n-grams within the plurality of vectors, a representative vector describing the text stream, and 5) identifying the character encoding of the text stream based on identifying a similarity between the representative vector and a neighboring vector within the plurality of vectors representing the character encoding. Various other methods, systems, and computer-readable media are also disclosed.
