adding electrically conductive filler particles consisting of graphite powder to the aqueous solution above a percolation threshold to form a mixture, wherein the graphite powder has a particle size of from 2 micrometers to about 40 micrometers, and ranges therebetween; and
depositing the mixture onto the substrate to form a low alpha particle emitting, electrically-conductive coating on the substrate, wherein the low alpha particle emitting, electrically-conductive coating blocks alpha particles from being emitted from the substrate.

DEAD-TIME CORRECTION SYSTEM AND METHOD

THERMO EBERLINE LLC, Oak...

1. A dead-time correction system for a pulse rate measurement device, the system comprising:a. a pulse counter that increments in response to pulses, the pulse counter having a selectable pulse counter read-out rate;
b. a pulse counter read-out (PCRO) storage register that stores an immediately preceding PCRO count;
c. a pulse-burst counter that also increments in response to pulses, the pulse-burst counter having a pulse-burst counter read-out rate that is faster than all but the fastest selectable pulse counter read-out rate;
d. a subtractor module in electronic communication with the pulse counter and the PCRO storage register that subtracts the preceding PCRO count from the pulse counter read-out count to output an uncorrected pulse count;
e. a selection module in electronic communication with the pulse-burst counter that selects the pulse counter read-out rate in response to input from the pulse-burst counter;
f. a multiplexer (MUX) in electronic communication with the subtractor module and the selection module, the MUX selecting from among at least two dead-time correction transforms (DTCT), the DTCT corresponding to the selected pulse counter read-out rate; and
g. a control-and-readout module in electronic communication with the MUX that applies the DTCT selected by the MUX to the uncorrected pulse count divided by the pulse counter read-out rate to output a dead-time corrected pulse rate.
