A passive and wireless sensor is provided for sensing at least one of magnetic field, temperature or humidity. The sensor can provide only one of the sensing functions, individually or any combination of them simultaneously. It can be used for various applications where magnetic field changes, temperature and/or humidity need to be measured. In one or more embodiments, a surface acoustic wave (SAW) sensor is provided that can measure one or more of a magnetic field (or current that generates the magnetic field), temperature and humidity. In one or more embodiments, a magnetoimpedence (MI) sensor (for example a thin film giant magnetoimpedance (GMI) sensor), a thermally sensitive (for example a Lithium Niobite (LiNbO.sub.3)) substrate, and a humidity sensitive film (for example a hydrogel film) can be used as sensing elements.

A method for managing a temperature anomaly in a hydrogen tank includes a temperature checking step for defining temperature values detected by temperature, a temperature comparing step for comparing the temperature values with each other and then checking whether there is a specific temperature difference among the temperature values, a temperature sensor judging step for judging the temperature sensor in which the specific temperature difference is generated as an abnormal temperature sensor, and judging the temperature sensor in which the specific temperature difference is not generated as a normal temperature sensor, and an abnormal temperature sensor managing step for applying the temperature value of the temperature sensor judged as the normal temperature sensor when the hydrogen tank in which the temperature sensor judged as the abnormal temperature sensor is provided is filled or amount of fuel in the hydrogen tank is calculated.

The invention relates to a temperature measuring device for measurement of the external temperature of the ambient air in a vehicle, wherein the temperature measuring device is disposed in a flow path of an air flow and the air flow can be generated from ambient air of the vehicle both through speed-dependent wind resistance of the vehicle and/or wind and also through a compressor unit disposed in the flow path.

Methods and systems are provided for using remote sensor data for a vehicle. The vehicle includes a control system, an interface, and a processor. The interface is configured to automatically obtain one or more remote sensor values via a wireless network from a remote source that is remote from the vehicle. The processor is coupled to the control system and the interface, and is configured to control one or more functions of the control system using the one or more remote sensor values.

A footwear system having a plurality of temperature sensors determines the emergence of an ulcer or pre-ulcer on a person's foot. After the plurality of temperature sensors generate a plurality of discrete temperature data values, the system and method form a temperature map representing substantially the actual geometric shape of at least a portion of the foot, and the distribution of temperatures of the at least a portion of the foot. Next, the method and system determine whether the temperature map presents at least one of a plurality of prescribed patterns, and produces output information indicating an emergence of an ulcer or a pre-ulcer on a given portion on the foot. The output information is produced as a function of whether the temperature map is determined to present the at least one of the plurality of prescribed patterns.
