Die Temperatursonde (11) weist einen Thermogenerator (31) für eine Energieerzeugung (19) auf. Der Thermogenerator (31) nutzt eine Temperaturdifferenz zwischen einer höheren Temperatur im Inneren des Ofens (35) und einer niedrigeren Kerntemperatur in einem Braten (15), in den die Temperatursonde (11) eingesteckt ist, als Energieerzeugung (19) zum Betrieb der Sendemittel (21).
Abstract:
A temperature sensing device accurately determines the core temperature of a warm blooded animal or human (22) based on at least one measurement of the temperature of the skin (23) of the warm blooded animal or human. The device includes a housing (1), and a first contact type temperature sensing element (6, 20) coupled to the housing (1). The first contact type temperature sensing element (6, 20) includes a first temperature sensor (6) that is operative to measure the temperature of the skin (23) when the first contact type temperature sensing element is in contact with the skin. The first temperature sensor (6) produces at least a first signal representative of the measured skin temperature. An electronic circuit uses the first signal to determine the core temperature of the warm blooded animal or human (22). An electronic communication device, such as a display (4), is coupled to the electronic circuit for communicating the core temperature to a user.
Abstract:
The invention relates to a method for determining the load state in a power system component, such as a line, in an electric power system. The invention is achieved by: determining the reference temperature for the conductor material, determining current and voltage on the line, transferring these values to a calculating unit, calculating a value for the actual resistance of the line, based on current and voltage values, calculating the temperature, and hence the degree of load, of the line based on the above values. The invention also relates to a system and a computer program for carrying out the method.

Abstract:
A method and system are provided for allowing non-contact temperature measurement of an animate body. More particularly, a transponder sensor device attached to an animate body is utilized to non-intrusively measure a temperature of the animate body in response to an interrogation signal transmitted over an air interface from a portable probe. In one embodiment, the sensor device is a passive device that is operative to collect energy from an interrogation signal emitted from the probe. In this regard, the sensor device does not require an internal power source. The collected energy is utilized to measure the temperature of the animate body and transmit a response signal containing temperature information back to the probe over the air interface.
