    摘要: A method of detecting a level of printable fluid in a container includes, with at least one sensing location on a die in thermal contact with the printable fluid in the container, sensing a voltage of a capacitor over time as current from the capacitor leaks through a field effect transistor (FET). The FET and capacitor are associated with the sensing location. The method may further include, based on the voltage of the capacitor over time and a threshold voltage, determining whether the printable fluid is present at the at least one sensing location.

    摘要: The present invention is related to a sensor (20) for measuring the thickness of a layer (19) of a grain/residue mixture as the layer is transported through the cleaning arrangement of a combine harvester. The sensor is preferably mounted on the support surface of a grain pan or a sieve of the cleaning arrangement and comprises a tower-shaped support structure (21) with sensor elements (22) attached to the structure and forming a vertical stack of sensor elements, so that a number of sensor elements is submerged in the advancing layer (19) and a number of sensor elements extend above the layer. The sensor elements are configured to measure an electrical property that changes as a function of the immediate surroundings of the sensor element. The sensor elements (22) are configured to be read out independently from each other.

    摘要: This invention relates to a device and method for measuring the depth of water and sediment deposition in pipes, channels, overland flows and tidal beaches. Sediment deposition may be detrimental to flood control in sewer systems. The invention is specifically concerned with measuring an electrical property such as the conductivity or capacitance in different mediums and therefore quantifying the depths of the different mediums. The measurement of an electrical property such as conductance or capacitance of the medium may also indicate the nature of the medium such as sediment structure, water salinity, and the presence of pollutants. The device includes an array of elongate, substantially mutually parallel electrodes each having a predetermined length, the lengths being incremented stepwise from a shortest electrode to a longest electrode. The device includes electronic circuitry to apply a potential difference across selected pairs of electrodes and to measure a resulting electrical property between each selected pair of electrodes, the measured electrical property providing an indication of a submersion depth of the pair of electrodes in the at least one medium.

    摘要: A gas-flow cryostat adapted for dynamic temperature regulation using a fluid level sensor; the cryostat further including one or more heaters coupled to various components of the cryostat. As fluid evaporates from a liquid coolant evaporation reservoir within the cryostat, the fluid level sensor and a feedback control module are adapted to monitor and dynamically control the level of evaporating coolant by regulating the heaters. Accordingly, the cryostat is adapted to dynamically control temperature about a specimen region within the cryostat. The cryostat can be used in various applications, including analytical laboratory equipment for measuring various physical properties of samples. Temperature sensors are further incorporated for added control and optimization of the cryostat.
