摘要:
The present invention relates to a sensor for measuring temperature of a fluid within a vessel, the vessel having a first region and a second region and the fluid having a temperature profile extending between the first region and the second region, the sensor comprising an array of elements, each element having a temperature-dependent parameter, the array being capable of deployment within or adjacent the vessel such that the array extends along the vessel for measuring the temperature profile, the elements of the array being coupled together between an input and an output, the input being coupled or capable of being coupled to a driving source for driving the sensors, and the output being coupled or capable of being coupled to a detector for measuring an aggregate of the temperature-dependent parameter from the array of elements. The invention further relates to a fluid temperature controller comprising a first input for receiving a first signal indicating a measurement of an aggregate of a temperature-dependent parameter from a sensor according to any preceding claim deployed within or adjacent a vessel containing a fluid having a temperature profile, a second input for receiving a second signal indicating a (preferably absolute) temperature of the fluid in the vessel and a processor configured to calculate a total thermal energy of the fluid in the vessel based on the first and second signals. The invention also relates to a combination comprising a sensing arrangement and a controller; a device; and a system.

The electronic device includes at least one sensor (171) configured to detect air flow in from an outside of the electronic device, and a plurality of openings (50, 60) formed in the electronic device. Further, the electronic device includes a duct (55) formed between the at least one sensor and at least one of the plurality of openings. A method for operating an electronic device having at least one sensor configured to detect air flow in from an outside includes detecting a motion of the electronic device by using a motion sensor, recognizing a pattern of the detected motion, and activating a foreign matter removing unit when the recognized pattern corresponds to a predefined first motion pattern.

The present invention relates to methods and devices for determining the weight of small particles, typically being nano-sized particles by use of resonating fibers in the form of elongate members being driven into resonance by an actuator or e.g. thermal noise/fluctuation. The frequency shift in resonance frequency due to depositing of nano-sized particles is correlated with the mass deposited on the elongate member and the vibration frequency of the elongate member is determined by a detector. The read-out from the detector is transformed into a mass deposited on the elongate member. Particles are deposited by letting a fluid with the particles flow past the elongate member.
