The present invention provides stability and proper display for the banner as well as easy replacebility.

Abstract: A plurality of serial data streams are transmitted on a corresponding plurality of lines at a common frequency in equal groups of symbols. A framing signal composed of groups of symbols corresponding in number to groups of data symbols is transmitted on an additional control line. Each group of symbols in the framing signal includes a majority of symbols capable of representing a first plurality of code words and a second plurality, substantially less than the first plurality, of valid code words, and a minority of symbols which constitute parity check symbols. Each of the valid code words consists of a first sub-group of similar symbols and a second plurality of similar symbols. For some of the valid code words the symbols in the first sub-group are similar to the symbols in the second sub-group. For other valid code words the symbols in the first sub-group are different from the symbols in the second sub-group.

Abstract: A method of testing data packets uses a program of selected microcode instructions of which at least one prescribes a comparison between a series of data patterns and a series of test patterns. Data patterns and test patterns are stored in dynamic random access memory. A first group of one of said series of patterns is read out and stored in temporary storage locations. A first group of the other of said series of patterns is read out and stored in temporary storage locations. Each of the patterns in the first group of the other series of patterns is compared, as it is stored, with a respective one of the stored patterns of the first series. The invention renders the testing of data packets more efficient.

Abstract: A device for the diagnosis of certain gastrointestinal pathogens includes a gelatin pharmaceutical capsule which contains a malleable drag material made of a mixture of beeswax and mineral oil. Embedded in the drag material is a narrow piece of thin sampling cloth with inwardly tapered ends. The free end of the sampling cloth is attached to a string which extends through a perforation in the capsule. The patient holds the free end of the string and swallows the capsule. The sampling cloth and drag material are retrieved for testing after the capsule is digested.
