Abstract: Systems and methods are disclosed that provide smart alerts to users, e.g., alerts to users about diabetic states that are only provided when it makes sense to do so, e.g., when the system can predict or estimate that the user is not already cognitively aware of their current condition, e.g., particularly where the current condition is a diabetic state warranting attention. In this way, the alert or alarm is personalized and made particularly effective for that user. Such systems and methods still alert the user when action is necessary, e.g., a bolus or temporary basal rate change, or provide a response to a missed bolus or a need for correction, but do not alert when action is unnecessary, e.g., if the user is already estimated or predicted to be cognitively aware of the diabetic state warranting attention, or if corrective action was already taken.

Abstract: A medium-voltage switchgear system includes a three-phase circuit breaker having first, second and third single-phase vacuum interrupters connected between respective first, second and third single-phase inputs and first, second and third single-phase outputs. Magnetic actuators are connected to first, second and third single-phase vacuum interrupters, which are configured to receive an interrupt signal and in response, actuate the respective vacuum interrupter connected thereto into an open circuit condition. A controller circuit is connected to each of the first, second and third magnetic actuators and generates an interrupt signal in response to a detected single-phase overcurrent or fault on a single-phase circuit and interrupt that single-phase circuit on which the single-phase overcurrent or fault occurred and maintain power on the remaining two single-phase circuits over which a single-phase overcurrent or fault was not detected.

Abstract: A processing solution delivery system and method for a photographic processor includes a plurality of chambers that are adapted to hold a distinct processing solution therein. A manifold is fluidly connected to the chambers and includes an inclined solution passageway. The manifold provides a connection between the chambers and an associated processor. Provided in a spaced manner along the inclined solution passageway are manifold bores which introduce solution at different points along the inclined passageway. With the present invention, it is possible to introduce wash solution at the highest point of the inclined processing path at the end of a processing cycle so as to assure the removal of contaminants from previously supplied solutions. Further, it is possible to introduce a bleach or fixing solution at the lowermost point of the inclined path to effectively and uniformly quench a development reaction.
