  • Patent number: 10175209
    Abstract: Apparatus and method measure the flow rate of fluid for use in calibrating fraction collection in a chromatography system. An injector inserts a detectable substance into a flow of fluid. A first detector, disposed in a path of the flow of liquid with the substance, produces a signal in response to detecting the substance in the flow of fluid. A second detector, disposed downstream from the first detector in the path of the flow of fluid with the substance, produces a signal in response to detecting the substance in the flow of fluid. A computing system receives each signal produced by the first and second detectors upon detecting the substance in the flow of fluid, and computes a volumetric flow rate of the flow of fluid based on a time interval between the signals and a volume of the path between the first and second detectors.

  • Patent number: 10132704
    Abstract: A method for measuring a preload of a fastener is described. The method, which may be practiced at least in part by an apparatus, includes establishing an initial value associated with an absence of the preload of the fastener and providing an adapter and a transducer rotatably coupled to the adapter. The transducer may be positioned in contact with the fastener. The transducer is caused to direct an incident ultrasonic wave to the fastener and to receive a reflected ultrasonic wave from the fastener. Data associated with the incident ultrasonic wave and the reflected sonic wave is used to generate a modified value associated with the preload of the fastener, and the preload of the fastener is calculated based on a difference between the initial value and the modified value.

  • Patent number: 10099699
    Abstract: A road surface condition estimation device includes a tire side device and a vehicle side device. The tire side device includes a vibration detection unit attached to a back surface of a tire tread and outputting a detection signal indicating a tire vibration magnitude, a signal processing unit, and a transmitter.

When the ground contact duration is ended, a transmission trigger is transmitted to the transmitter and the transmitter transmits the road surface condition data. The vehicle side device estimates a road surface condition of the travelling road based on the road surface condition data.

  • Patent number: 10082416
    Abstract: An electronic liquid level gauge assembly includes an electronic display located in a housing connected to a tank. The display has first and second display portions for indicating liquid level condition. A first electronic sensor senses a change in magnetic field of a magnet associated with a liquid level transducer, with magnet rotation being proportional liquid level change. A processor determines a temperature-compensated liquid level condition by correlating the liquid level signal with temperature measurement of the liquid. A temperature-compensated vapor space can also be calculated based on tank information and properties of the liquid. Signals related to the temperature-compensated liquid level and vapor space are sent to the display and wirelessly transmitted to a smart phone or the like for remotely viewing the tank information. The smart phone also includes a special app for sending information, firmware updates, and display configuration data to the electronic gauge assembly.

  • Patent number: 10024763
    Abstract: Methods and systems for improving the uniformity of a tire by determining one or more high speed uniformity parameters of the tire are provided. The high speed uniformity parameters can be determined by continuously acquiring uniformity data while ramping the tire to and from high speeds. For instance, measured uniformity data can be continuously collected for the tire as the tire is increased to high rotational speeds and decreased from high rotational speeds. The measured uniformity data can then be analyzed to determine one or more high speed uniformity parameters for the tire. For instance, the measured uniformity data can be corrected for non-high speed uniformity contributions to the uniformity measurements, such as contributions resulting from non-uniformity of a road wheel use to load the tire during uniformity testing, contributions resulting from mass unbalance of the tire, and contributions from low speed uniformity parameters of the tire.
