  • Biochemical sensor device and method
    Patent number: 5653862
    Abstract: Degradation of multielectrochemical sensors in a common flow stream is averted by positioning any sensors having as its associated enzyme an oxidoreductase enzyme capable of producing, as a result interaction with its respective substrate, an oxidizing agent downstream of the other enzyme sensors not having such oxidoreductase enzyme.

  • Container identification apparatus
    Patent number: 5576504
    Abstract: An apparatus is provided for identifying each of a predetermined plurality of liquid containers, some of which are stoppered and others of which are open-mouthed and for extracting liquid therefrom. The apparatus comprises an upper arm and a lower arm and a sensor responsive to relative motion therebetween, relative motion between the arms causing a container identity signal representative to be generated. A single needle is used to penetrate stoppers when present and extract liquid from the container.
