Abstract: A device includes: a first portion configured to be grasped by the hand of the user, and a second portion defining a reservoir containing a control material, wherein the control material contains a target analyte in a known or predetermined concentration. A method of verifying the accuracy of an analyte monitoring device includes receiving a fluid sample, identifying the fluid sample as a control solution, and analyzing the fluid sample.

Abstract: A daisy chained ethernet network data acquisition system for use in industrial processes is shown. The system employs standard category five twisted-pair connectors, each having four twisted-pairs associated therewith. Two of the twisted-pairs are employed for transmitting and receiving command signals and data, while the remaining two are employed for transmitting a common clock and synchronizing signal to each of the various stages of the processing line at which data is to be acquired. The system thus allows for the time correlated acquisition of data from a plurality of stages or stations of a lengthy processing line by employing ethernet interconnection.

Abstract: A garbage container includes an air conduit directed within the container coextensively of a side wall thereof extending into the container cavity, such that the air conduit includes side walls having side wall openings to effect vacuum release when a plastic liner is positioned within the garbage can.

Abstract: A display system including a programmable video graphic controller allows for continuous smooth panning through memory which is larger than the system's video memory. The video memory is continuously updated with new image data so as to form two duplicate images within video memory. When an edge of video memory is reached, the displayed image may be shifted from one of the duplicate images to the other within video memory to allow continuous panning without the need to stop and refresh the image data every time an edge of video memory is reached.

Abstract: A circuit for interpolating discrete data points or horizontal line segments of a single valued function in one direction into a continuous line display. So that only one value need be produced from a memory for each display position along one axis of an x,y coordinate system display, the circuit generates lines parallel to the other axis which connect the display at adjacent positions along the first axis. The circuit receives and displays a line of data; delays the line of data by one clock pulse and displays the delayed line; compares the line and delayed line to determine the ends of data in the line; stores the position of the ends of data in a shift register; displays the output of the shift register; and returns the output of the shift register to the input of the shift register for each end position until data is received in a position adjacent the end position.

Abstract: A capacitive gauging apparatus in which a single central processing unit is connected to a plurality of gauging heads each gauging head having a further plurality of gauging probes. The system then multiplexes the probes and heads to enable the central processing unit to receive serially the output from each of the heads and produce an analog or digital signal which indicates distance between each of the probes and the work piece. A central microprocessor transforms these signals into an output for visual display or calculates the difference between these signals and an ideal master work piece. Further, a highly temperature stable, low capacitance, high impedance amplifier is used in conjunction with each of the probes so that the output signal from each of the probes is stable and accurate over a wide range of conditions.
