Thermostatic Alarm for House Heaters

Smoke alarm ownership and house fire death rates in children.

Residential fires are the second leading cause of unintentional injury death among children ages 1–14 in the UK. Case-control data show that smoke alarms are associated with a substantial reduction in the risk of death in the event of a house fire, the protective eVect being greatest in fires involving children under 5. In the UK, the Home OYce recommends that all homes are fitted with smoke al...

Elevated thermostatic setpoint in postoperative patients.

BACKGROUND The mechanism and clinical relevance of increased core temperature (Tc) after surgery are poorly understood. Because fever is used as a diagnostic sign of infection, it is important to recognize what constitutes the normal postoperative thermoregulatory response. In the current study the authors tested the hypothesis that a regulated increase in Tc setpoint occurs after surgery. ME...

Minimum Time for a Hybrid System with Thermostatic Switchings

In this paper we study a minimum time problem for a hybrid system subject to thermostatic switchings. We apply the Dynamic Programming method and the viscosity solution theory of Hamilton-Jacobi equations. We regard the problem as a suitable coupling of two minimumtime/exit-time problems. Under some controllability conditions, we prove that the minimum time function is the unique bounded below ...

Method for alarm prediction

The goal of this paper is to show a predictive supervisory method for the trending of variables of technological processes and devices. The data obtained in real time for each variable are used to estimate the parameters of a mathematical model. This model is continuous and of first-order or second-order (critically damped, overdamped or underdamped), all of which show time delay. An optimizati...
