Abstract: A stored model is comprised of a plurality of candidate contextually-described states along with state-to-state transitions between at least some of this plurality of candidate contextually-described states. This stored model can be agnostic with respect to any particular application. One can then access at least one policy as pertains to a particular application to be effected by that platform and apply that policy to modify at least one of the state-to-state transitions to thereby provide a modified version of the stored model that corresponds in particular to the particular application to be effected. By one approach, the aforementioned policy can comprise, at least in part, an indication of a relative preference as pertains to one or more of the state-to-state transitions. This can comprise, for example, a weighting factor to be applied with respect to one or more of the state-to-state transitions.

Abstract: A breath detection/confirmation device includes a sensor for determining if an infant or other person is breathing, and a means for generating a human perceptible signal in response thereto. In use, the sensor is placed adjacent the infants or person's mouth/nose, and a light or some other signal indicates to the user if the infant or person is breathing.

Abstract: EMI spur interference is reduced in a system where the desired signal has periodically repeating components without destructively interfering with the repeating components. The frequency of the spur interference is determined (203) and fed to a notch filter (201) so as to center the notch at the frequency of the spur interference. Determination of the frequency is scheduled (601) to avoid cancellation of desired periodically repeating components of the signal.
