    摘要: A reconfigurable clustered system of data-entry terminals includes a plurality of physically separate data-entry terminals coupled to a communications link in a cluster. Each of the terminals includes a programmable digital processor for transferring data and programs over the communications link. Each of the terminals further includes entry devices for communicating information between an operator and the programmable processor. At least two of the terminals are media terminals further including a storage for containing both data from the terminals and programs for all of the terminals in the cluster. Selection circuitry is provided to designate any one of the media terminals as a primary media terminal, such that all other terminals in the cluster, including others of the media terminals, exchange both data and programs with the primary media terminal. The selection circuitry is operable to designate different ones of the media terminals as the primary media terminal without the requirement of any physical reconfiguration of the cluster of terminals.

    摘要: A differential light scattering photometer is disclosed for testing samples of bacteria in suspension. A plurality of cuvettes containing the samples are placed in a cuvette holder or carousel which rotatably places each cuvette in position to interrupt a laser beam. A detector rotates in an arc about each sample to produce output signals representing the scattered light intensity as a function of angular location, relative to the incident laser beam, about the sample. A control differential scattering pattern is produced and compared with test differential scattering patterns derived from test samples having added antibiotics. The patterns are compared by data processing to produce an output punched card indicative of bacterial sensitivity to each antibiotic. The data processor is responsive, through pattern comparison, to various responses of the bacteria, i.e., whether the antibiotic is bactericidal, bacteriostatic or the bacteria actually metabolize the antibiotic. An appropriate protocol and process is disclosed.
