  • Publication number: 20040117565
    Abstract: A peripheral device may include an interface configured to interface to a memory bus and a functional unit coupled to the interface and configured to perform a peripheral device function on data accessed by the interface. The interface may be configured to perform a data access in response to memory control, address, and data signals on the memory bus. The functional unit may be configured to perform various peripheral device functions such as data communication functions, video functions, printing functions, mass storage functions, and human interface controller functions.

  • Patent number: 5223222
    Abstract: An automatic chemistry analyzer includes a flow cell mounted so that flow through the cell and tubing connected to the cell is visible from the front of the housing. The electrolytes to the cell are removably plugged into the cell from their rear. The probe aspirating sample fluid into an injection cell is simultaneously washed by diluent and the diluent mixes with the fluid sample. Waste fluid from the flow cell is fed to a basin which then feeds under gravity to a waste drain. A ratio pump is formed by selected syringes which are band driven to deliver accurately prerequisite volumes of reagents to the flow cell. The solution ground to the system is on the inlet line for sample adjacent the entrance to the flow cell of fluid thereby minimizing electronic noise. Only two motive means are necessary, one to effect horizontal and rotational movement of the sample tray, and a second to effect vertical motion of a crane mounted probe operative between sample cups and an injection cell.
