  • Patent number: 8015872
    Abstract: A SAW-based humidity sensor apparatus with integrated signal conditioning on the same substrate. A micro-electronic circuit can be processed at a silicon substrate to obtain on-chip signal conditioning internally and the silicon substrate can be covered with a protective layer of, for example, silicon nitride. Surface acoustic wave media (e.g., a ZnO film) can be coated on top of the protective layer. A humidity sensitive film and two sets of interdigital transducers can then be deposited on the surface acoustic wave media. The humidity sensitive film absorbs moisture and changes the receiving frequency at the two sets of interdigital transducers. The output from the two sets of interdigital transducers can be processed by the micro-electronic circuit, which eliminates common mode noise and generates an output signal proportional to the humidity value tested.

  • Patent number: 8015866
    Abstract: Disclosed is a liquid detection unit having a liquid detection chamber, a detection portion including a detection space communicating with the liquid detection chamber via a through hole of a detection portion installation member and a piezoelectric sensor which detects remaining vibrations, and a movable member including a detection space sealing surface which is urged by an urging member and thus comes to abut against one surface of a detection portion installation member. The liquid detection chamber includes an abutting surface abutting against a second sealing surface being in contact with a first sealing surface of the movable member and the detection portion installation member. When a distance between the first sealing surface of the movable member to the detection space sealing surface is defined as L1 and a distance between the second sealing surface of the liquid detection chamber to the abutting surface is defined as L2, the relationship L1>L2 is satisfied.

  • Patent number: 8015888
    Abstract: A gas sorption sample chamber contains a plurality of thin-film substrates and fluidly couple said substrates to a Sieverts' device or other gas sorption analyzer. The thin-film substrates are held in proximity to each other in the sample chamber in a columnar arrangement, either in a stacked or slightly spaced configuration, to reduce free-gas volume in the sample chamber, thereby improving sorption test accuracy. The interior geometry of the chamber is configured to provide a minimal clearance between the thin-film substrates and the internal surfaces of the chamber, so that essentially all of the chamber volume is occupied by thin-film sample material and inactive substrate material. To facilitate use in a glove box, the chamber may be configured with a removable sample cartridge in which thin-film substrates are placed so that all substrates may be loaded and unloaded as a group.

  • Patent number: 8006398
    Abstract: A measurement system has a surface sensing device mounted on an articulating probe head, which in turn is mounted on a coordinate positioning apparatus. The surface sensing device is moved relative to a surface by driving at least one of the coordinate positioning apparatus and probe head in at least one axis to scan the surface. The surface sensing device measures its distance from the surface and the probe head is driven to rotate the surface sensing device about at least one axis in order to control the relative position of the surface sensing device from the surface to within a predetermined range in real time.

  • Patent number: 8006555
    Abstract: A cap member for covering a sensor unit such as a rotational speed sensor is composed of a cylindrical wall, a thin bottom wall and an open end to be closed with a closing member. The cap member is formed by molding a resin material. Molten resin is injected into a cavity formed by an inner die and an outer die. After the injected resin is cooled, the inner die is separated from the molded cap member. If the molded cap member adheres to the inner die, it would be difficult to separate the inner die from the cap member by pulling out the inner die in the axial direction. A structure anchoring the cap member to the outer die is formed on an outer surface of the cylindrical wall. The anchoring structure may be formed in a shape of a ring or rings surrounding the center axis of the cap member. Alternatively, the anchoring structure may be formed in a shape of a depressed groove or grooves.

  • Patent number: 8006556
    Abstract: A method for measuring positional changes of an object, including rotation about any or all of three axes, using linear accelerometers. There is disclosed a method of using a linear accelerometer to integrate two other 3D linear accelerometers in order to measure and supply for further use six-dimensional information, that is, translation in three dimensions and rotation about three axes. Two linear accelerometer sensors are used to determine all but one of the variables in the six degrees of freedom. Output from a third accelerometer generates the data need to determine a sixth, rotational, degree of freedom. The need for a gyroscope for detecting changes in heading (i.e., yaw or azimuth) may therefore be avoided.

  • Patent number: 8001827
    Abstract: A sensor is provided, in particular a gas sensor for determining the concentration of a gas component in a measuring gas, which has a sensor element that projects from a housing by a measuring-gas-side end section exposed to the measuring gas, and a sheath tube having gas passageways, which is placed over the measuring-gas-side end section and affixed on the housing. To prevent condensation of water vapor contained in the measuring gas in the measuring space enclosed by the housing and the sheath tube, and thus the production of water droplets that reach the hot sensor element, sheath tube and/or sensor element are/is thermally decoupled from the housing. The thermal decoupling is produced using, for instance, a flange sleeve made of a material having poor thermal conductivity, which separates the sheath tube from the housing by a flange and, via a sleeve section, is inserted in the space between the housing and the measuring-gas-side end section of the sensor element.

  • Patent number: 7997120
    Abstract: A method for pressure testing a threaded component is provided. A cap includes a female threading that is matched with a threading of a first male threaded element. The cap is made up onto the first male threaded element of a component to be tested so as to compress a sealing ring between metal surfaces of the first element and the cap, and a test pressure is established inside the component. The male element has an annular lip which is capable of deforming radially outwardly under the effect of the test pressure. Between a radially outward surface of the lip and a facing surface of the cap, at the end of makeup there exists a clearance having a value which has been selected sufficiently small so that, under the effect of the test pressure, the lip bears on said facing surface without undergoing plastic deformation.

A MEMS accelerometer includes a proof mass, a planar coil on the proof mass, a magnet, a first pole piece positioned proximate a first side of the proof mass, and a second pole piece positioned proximate a second side of the proof mass. A magnetic flux field passes from the magnet, through the first pole piece, through the planar coil at an angle between approximately 30 degrees and approximately 60 degrees relative to the coil plane, and into the second pole piece. The first pole piece may extend into a first recessed area of a first housing layer and the second pole piece may extend into a second recessed area of a second housing layer. A method includes sensing a capacitance of a pickoff in the MEMS accelerometer and rebalancing the MEMS accelerometer by sending a current through the planar coil.
