An abnormality detection device includes a first temperature detector, a power consumption calculator, a second temperature detector, and an abnormality determination unit. The first temperature detector detects a detection temperature of an FET that is mounted on a mounting surface of a substrate and that generates heat when energized. The power consumption calculator obtains power consumption of the FET. The second temperature detector detects a detection temperature of a heat sink that is provided on a side opposite to the mounting surface side of the substrate and that dissipates the heat generated in the FET. A controller determines an abnormality in a heat dissipation path P between the FET and the heat sink based on a thermal resistance determined according to the detection temperature detected by the first temperature detector, the detection temperature detected by the second temperature detector, and the power consumption obtained by the power consumption calculator.

A method for filling a tank with pressurized gaseous hydrogen from at least one source storage containing pressurized gaseous hydrogen at a first defined temperature and at a defined pressure higher than the pressure in the tank to be filled, in which hydrogen is transferred from the source storage to the tank by pressure balancing via a filling circuit having an upstream end linked to the source storage and a downstream end linked to the tank, and in which the at least one source storage exchanges heat with a member for heating the gas stored in the source storage, during at least a part of the transfer of hydrogen from the source storage to the tank, the gas contained in the source storage being heated to a second defined temperature that is higher than the first temperature.

A temperature control device (2) comprises a number of active thermal sites (6) disposed at respective locations on a substrate (10), each comprising a heating element (13) for applying a variable amount of heat to a corresponding site of a medium and a thermal insulation layer (16) disposed between the heating element and the substrate. At least one passive thermal region (8) is disposed between the active thermal sites (6) on the substrate (10), each passive thermal region (8) comprising a thermal conduction layer (18) for conducting heat from a corresponding portion of the medium to the substrate (10). The thermal conduction layer (18) has a lower thermal resistance in a direction perpendicular to a plane of the substrate (10) than the thermal insulation layer (16). This enables precise control over both heating and cooling of individual sites in a flowing fluid, for example.

A system for modifying controllable elements of a structure based on an array of conditions, particularly a distance of a user or operator from the structure, deviations from an expected travel path to the structure, activities conducted either along or while deviating from the expected travel path, traffic, a core body temperature of the user or operator, and other factors. The controllable structure elements can include, for example, heating and air conditioning (HVAC), alarm, lights, and appliances.

A temperature-sensing device configured to monitor a temperature is disclosed. The temperature-sensing device includes: a first capacitor comprising a first oxide layer with a first thickness; a second capacitor comprising a second oxide layer with a second thickness, wherein the second thickness of the second oxide layer is different from the first thickness of the first oxide layer; and a control logic circuit, coupled to the first and second capacitors, and configured to determine whether the monitored temperature is equal to or greater than a threshold temperature based of whether at least one of the first and second oxide layers breaks down.

A structure of an aquarium heater with off-water overheat protection, wherein a control box with a control circuit is set inside. The control circuit includes: setting a temperature-control module; connecting with an electric heater; and connecting with either an overheat sensor or an off-water protection sensor; wherein the control circuit consists of a single chip, an electric relay box, and a plurality of resistors, capacitors, diodes, and transistors to constitute a complete electric circuit. Therefore, saving the electric energy and avoiding the conditions which the heating temperature is too high or the electric heater is emptily burned to damage because of the off-water can be achieved through the overheat sensor senses the temperature or the off-water protection sensor senses weather the electric heater is off water or not, and then the temperature-control module does the temperature comparison to control the electric heater to heat or not.
