    Abstract: A plunger is moved downwardly in predetermined distance while the tip of the sample probe is immersed in a sample to suck the sample into the probe. A pressure sensor detects the pressure fluctuation during the suction operation, an AD converter converting the signals into digital signals to send the signals for a signal processing unit. The signal processing unit extracts feature variables data of a suction waveform to calculate the Statistical distance from normal group data. The Statistical distance an a threshold value are compared with each other, it is judged that there is an abnormality in the suction operation when the Statistical distance is more than or equal to the threshold value. When the Statistical distance is smaller than the threshold value, an operation is proceeded to a discharge operation.

This first strip of over-molding faces both the first part and one of the electrodes, thereby providing two capacitances in series, namely, a vacuum capacitance between the electrode and the inner surface of the first part, and a solid capacitance between the inner surface of the first part and the first strip, and means for measuring change of current value in the first strip, which corresponds to a vacuum loss inside a vacuum breaking apparatus.

  • Patent number: 8624705
    Abstract: A storage system for material containers provides a readable ID distinguishing each container, and includes a scale that weighs containers, so that the system can distinguish between containers that are sufficiently loaded to be effective and containers that are insufficiently loaded. The system preferably includes storage for containers held in contact with readers of the container IDs. This allows a controller to keep track of containers checked out for use and returned for storage, and to identify containers that have been discharged.

  • Patent number: 8593290
    Abstract: An overfill probe is utilized in each compartment of a multi-compartment transport tanker and has a depending sensing tube for detecting liquid overfill conditions. An overfill detector is within the bottom end of the probe tube and is thus protected from damage. Internal damage to the probe and malfunction of the system also precluded by connecting the exposed cap of the probe to the detector by a longitudinally extensible, stretchable cable extending through the tube to the detector, or a circuit board may be retained within the depending tube. Additionally, a thermistor socket and an optic socket are provided which are part of the overfill protection system, each having contact connections that may be readily replaced when worn without removing or replacing the wiring within the socket assembly.

  • Patent number: 8558705
    Abstract: A RF resonator for sensing a physical or an environmental parameter includes a substrate having a substrate surface. A polymer-derived ceramic (PDC) element is positioned on or within the substrate surface. The RF resonator has a resonant frequency that changes as a function of the physical or environmental parameter. A system for wirelessly sensing at least one physical or environmental parameter includes at least one RF resonator and a wireless RF reader located remotely from the RF resonator for transmitting a wide-band RF interrogation signal that excites the RF resonator. The wireless RF reader detects a sensing signal retransmitted by the RF resonator and includes a processor for determining the physical or environmental parameter at the location of the RF resonator from the sensing signal.

    Abstract: An enhanced dive computer functionality providing a diver positioning system integrated into a dive computer and a modified Display Integrated Vibrating Alarm device controlled by the dive computer to allow for decompression integrated guidance and a buddy signalling device. The diver positioning system allows for automatically determining the diver's position by tracking the diver's location in three dimensions within a water column, or portion of the body of water in which the diver operates bounded by the surface and the maximum dive depth, during a dive. A modified Display Integrated Vibrating Alarm allows for guiding a diver through a controlled decompression ascent and a method for automatically warning companion or nearby divers of imminent danger of injury or death to a subject diver.

  • Patent number: 8508375
    Abstract: A comparative pressure monitoring instrument (10) houses a switch (14) having first and second ports (18) and (20), and a high flow impedance 16. The ports (18) and (20) are in fluidal communication with a first pressure source (72) and a second pressure source (82) respectively. The impedance (16) is coupled (i.e. shunted) across the switch ports (18) and (20) and the first and second pressure sources (72, 82). The switch (14) switches between a first state characterised by a pressure differential across the impedance (16) being less than a preset level and a second state characterised by the pressure differential across the impedance (16) being equal to or greater than the preset difference. Any difference in pressure between the sources (72) and (82) will cause an air/gas flow through the impedance (16) and thus a pressure drop across the impedance (16).
