Abstract:
A heat flow sensor for a heat flux differential scanning calorimeter comprising twin thermopiles. The thermopiles each comprise positive and negative thermocouple alloys and electrically insulating ceramic components. Diffusion bonding is used to form thermocouple junctions in the thermopiles between the positive and negative thermocouple elements, and to attach the thermocouple elements to the ceramic components.

Abstract:
A method for determining the relative body temperature of a warm-bodied animal is described. The method, in part, involves an article of manufacture that provides a manifestation, or visually observable indication on an exterior surface, of a relative state of the warm-bodied animal body temperature, either being too cold or too hot, as a measure against relative levels of hypothermia or hyperthermia, or poor circulation.
Abstract:
A temperature difference between a first thermal sensor and a second thermal sensor on a first die is determined. The temperature difference is transmitted from the first die to a circuit on a second die. A temperature from a thermal sensor on the second die is determined. The temperature difference and the temperature from the thermal sensor are utilized on the second die to modify operational characteristics of one or more circuits on the second die.
Abstract:
A sensor (10) for indicating the presence or absence of a liquid adjacent the sensor (10). The sensor (10) has first and second spaced apart thermistors (26, 28) and means (38) for controllably heating the second thermistor (28). A voltage is applied to a circuit including each of the thermistors (26, 28) and the voltages at the input (30, 30') of each of the two thermistors (26, 28) are compared by a voltage comparator (42). In response to these voltages differing by more than a preselected amount, the voltage comparator (42) produces a signal used to activate either a warning system or an engine shut-down system.
Abstract:
In one embodiment, a method of temperature control comprises receiving temperature readings from a temperature sensor on a chip, calculating one or more second derivatives of temperature with respect to time based on the temperature readings, and determining whether to perform temperature mitigation on the chip based on the one or more calculated second derivatives of temperature.
Abstract:
Exemplary embodiments of an apparatus according to the present disclosure comprise a radiative heating system with a radiation source configured to generate radiation for absorption by an object. A magnetic resonance system is provided with one or more coils configured to transmit and receive radio frequency energy to and from the object. A processor is configured to determine at least one of a temperature of the object and a change in the temperature of the object, based on the radio frequency energy received. A magnetic field source can be configured to generate a magnetic field within the object, and the radio frequency of the energy can be selected for magnetic resonance interactions in the object, based on a strength of the magnetic field.
Abstract:
Die Erfindung betrifft ein Verfahren zur Bestimmung der Temperaturänderung einer Stromzuleitung eines Ladegerätes, indem in einem ersten Schritt der elektromagnetische Eingangsimpuls in die Stromzuleitung eingekoppelt wird, wobei der elektromagnetische Eingangsimpuls in der Stromzuleitung reflektiert werden kann und der reflektierte Teil als reflektierter elektromagnetischer Ausgangsimpuls in das Ladegerät zurückkehrt, in einem zweiten Schritt die Impulsform des reflektierten elektromagnetischen Ausgangsimpulses ermittelt wird, in einem dritten Schritt die Impulsform des reflektierten elektromagnetischen Ausgangsimpulses mit einer Referenzimpulsform des reflektierten Referenzimpulses verglichen wird, in einem vierten Schritt die Temperaturänderung aus dem Vergleich der beiden Impulsformen ermittelt wird.
