  • Patent number: 10780750
    Abstract: Method of determining the footprint of a tire on the ground, using devices already installed in standard production tires. Since the frequency of the transmitter clock present in a wheel unit is perturbed by mechanical vibrations when the tire contacts the ground, the frequency variations of the reference clock are representative of the value of the footprint. The method therefore includes determining the footprint on the ground of a tire of a wheel by measuring continuously, as a function of time, a signal representative of the variations in frequency of the reference clock supplied at the output of the time control device; determining a time interval during which the frequency variations of the reference clock occur; and, on the basis of the rotation speed of the tire, deducing therefrom an angular range of contact (?) corresponding to the footprint between the ends representing the ground contact length of the tire.

  • Patent number: 10782352
    Abstract: A test meter and related method for monitoring the condition of a backlight battery of the meter in which the meter includes a housing, controller, display with backlight and a battery monitoring circuit. An off-time of the meter is measured and compared to a predetermined recovery time of the backlight battery. If the off-time of the meter is greater than the predetermined recovery time of the backlight battery, a voltage of the backlight battery is measured at a predetermined time after energizing the backlight and compared to a first predetermined voltage in excess of a threshold voltage of the backlight battery. If the measured voltage is less than the first predetermined voltage, the measured voltage is compared to a second predetermined voltage between the first predetermined voltage and the threshold voltage. A battery depletion warning is displayed if the measured voltage is less than the second predetermined voltage.

  • Patent number: 10761064
    Abstract: Methods are provided for making, processing, and analyzing in situ measurements to indicate presence of thin bedding planes of weakness in a formation. Bedding planes as small as a few inches and smaller are identified using an ultrasonic borehole tool. In one embodiment, detected pseudo-Rayleigh waveforms are processed to determine whether multiple events are detected. If so, lamination and a likely bedding plane of weakness are identified. In another embodiment, a sonic borehole tool is run in conjunction with the ultrasonic borehole tool. Indications of shear and pseudo-shear wave speeds are compared, and where different, a bedding plane of weakness is identified. In another embodiment, a microresistivity imager is run with the ultrasonic borehole tool, and at locations where multiple events are not detected, the image obtained by the imager is inspected to find locations of sharp contrast with adjacent locations to thereby identify bedding planes of weakness.

  • Patent number: 10751622
    Abstract: In a virtual reality environment a user's movements are coupled, meaning the user cannot walk and look in different directions. Discloses are methods and systems for soft decoupling the movements of the user in a virtual reality environment, enabling the user to look and walk in different directions simulating real-world interactions. The soft decoupling is performed by receiving acceleration and orientation data from sensors attached to the user. A heading and a heading delta based on a ratio are calculated. The calculated heading and a velocity are translated into soft decoupling inputs for the virtual reality environment.

  • Patent number: 10746624
    Abstract: The invention relates to a method for determining the root mean square value of a vibration variable that is measured on a machine. A test measurement is carried out in order to obtain a test signal of the vibration variable with a test signal length; the influence of shortening the signal length of the test signal on the associated root mean square value is estimated and the relative deviation of the root mean square value emerging for a shortened signal length from the root mean square value emerging for the full test signal length is estimated therefrom as a function of the signal length to obtain a root mean square value error function; and a measurement of the vibration variable is carried out for determining the root mean square value. The measurement duration of this measurement is selected on the basis of the root mean square value error function.

  • Patent number: 10705147
    Abstract: The present invention improves the detection accuracy of the state of charge of a battery. A coulomb count value CC is generated by integrating a charge/discharge current IBAT of a battery (S100). An SOC value SOC1 is calculated (S102). Based on an SOC-OCV characteristic predetermined for the battery, an OCV value OCV1 corresponding to the value SOC1 is generated (S112). A voltage VBAT of the battery is detected (S104). A voltage drop VDROP1 between OCV1 and a detected value VBAT1 of the voltage VBAT is generated (S114). A value OCV2 greater than the minimum operating voltage of the system by ?V, which corresponds to the voltage drop VDROP1, is generated (S116). Based on the SOC-OCV characteristic, an SOC value SOC2 corresponding to OCV2 is generated (S118). Based on the value SOC2, at least one of the values SOC1, CC, CCFULL, and SOC-OCV characteristics is corrected.

  • Patent number: 10704905
    Abstract: Identifying and estimating values of atmospheric conditions for use in estimating an altitude of a mobile device. Systems and methods for monitoring one or more conditions before estimating an altitude of a mobile device may receive a reference pressure that was computed using a measurement of pressure from a first reference pressure sensor at a first location, wherein the received reference pressure specifies an estimated pressure for a reference altitude, and determine if a threshold change in measured pressure by the first reference pressure sensor is detected. If the threshold change in measured pressure is detected, the systems and methods may compute a calibration value for the first reference pressure sensor, or if the threshold change in measured pressure is not detected, the systems and methods may identify a previously-determined calibration value.
