The conductivity offset, which is the conductivity of the water, is used to normalize the conductivity estimated for the chemical solution relative to the component chemical product in the solution. During various points in time during operation of the utility device, the normalized conductivity is compared to a conductivity setpoint, and if the normalized conductivity falls below the conductivity setpoint, a specified volume of the component chemical product is supplied to the solution tank.

  • Patent number: 6892129
    Abstract: A vehicle electronic control system has a control CPU and a monitor CPU. The control CPU performs a fail-safe processing thereby to reduce an engine output torque, when the monitor CPU monitoring the control CPU detects that the control CPU fails to perform throttle control for an engine. When the monitor CPU detects that the control CPU fails to perform the fail-safe processing, it performs a fail-safe processing in place of the control CPU. In this fail-safe processing, the monitor CPU continues to reset the control CPU so that the engine may be forcibly stopped.

  • Patent number: 6865426
    Abstract: The present disclosure relates to a method for communicating and applying adaptive security to a data stream comprising a plurality of data packets. The method comprises the steps of identifying a desired security level range and a desired actual security level which falls within the desired security level range. The availability of a number of security processor operations at the host is determined so that, if needed, computing resources at the host can be reallocated to ensure that the data stream can be verified at the desired actual security level. If there are not sufficient resources available for reallocation at the host, communication resources can be reallocated, for example by changing the bandwidth of the data stream or another incoming data stream.
