Abstract
Abstract An object oriented architecture is used within individual monitoring units. The monitoring devices include circuitry which receives an electrical signal and generates at least one digital signal representing the electrical signal. Objects within such individual monitoring units include modules which perform a function and registers which contain the inputs, outputs and setup information for the modules. Methods can be invoked on all objects to change or query the operation or configuration of the device. At least one of the modules receives the digital signal as an input and uses the signal to generate measured parameters. Additional modules take measured parameters as input and generate additional parameters therefrom. The module may be linked in an arbitrary manner to form arbitrary functional blocks.
