摘要:
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.

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.

A computer system including one or more PCMCIA expansion slots allows video and/or audio capabilities to be added to the system through a standard PCMCIA interface, utilizing multimedia type PCMCIA peripheral cards. A PCMCIA host adapter integrated circuit interrogates a PCMCIA peripheral card to determine whether or not the PCMCIA peripheral card is a multimedia type PCMCIA peripheral including video or audio capability. If the PCMCIA peripheral card is a multimedia type peripheral, the PCMCIA host adapter integrated circuit couples the PCMCIA peripheral card directly to the graphics and sound controller integrated circuits, using the standard PCMCIA interface and bypassing the host system bus. Otherwise, if the PCMCIA peripheral card is a standard PCMCIA peripheral, then the PCMCIA host adapter integrated circuit interfaces communications between the PCMCIA peripheral card and the host system bus in a conventional manner. The computer system includes a multi-windowing or display function whereby a typical computer applications program may be operating and displayed in a first window or display while the system simultaneously displays a playback or live video signal from a multimedia type peripheral card in a second window or display.
