  • Patent number: 10184791
    Abstract: A method for measuring three dimensional coordinates of each of points on a surface of an object includes pre-storing an algorithm that includes a plurality of parameters. A driving device is controlled to drive a distance sensor to move to each of measuring positions, and a first distance between each of the points and the distance sensor is obtained using the distance sensor. Each position information of the distance sensor is obtained using a position sensor, when the distance sensor is located at each of the measuring positions. Once a parameter of a reference coordinate is determined, the three dimensional coordinates of each of the points is computed using the algorithm based on the plurality of parameters.

  • Patent number: 10024966
    Abstract: A system and method for determining a distance to a surface of interest, such as in a Time of Flight (ToF) system, includes projecting modulated electromagnetic radiation of at least two frequencies to a point on the surface of interest, receiving the electromagnetic radiation reflected from the point on the surface of interest and demodulating the received electromagnetic radiation. Whereupon, a weighted phase difference between the frequencies may be calculated, in accordance with the present systems and methods, and one bin for each of the reflected frequencies for an actual distance to the point on the surface of interest is calculated using the weighted phase difference. A final phase of the bin for the actual distance is calculated as a weighted average of the phases of the bins based on the reflected signal strengths, and the actual distance to the point on the surface of interest is then output.

For each frequency, a matrix NE×NR of complex amplitudes of vibrational components having this frequency is extracted. These matrices are decomposed into singular values, the smallest are eliminated, and the singular vectors associated with the singular values retained, a base of the space of the reception signals is formed, for each frequency. The contribution of each plane wave, characterized by its velocity, in this base is calculated.

  • Patent number: 8886449
    Abstract: In some embodiments, methods and systems are provided for assisting a user in determining a real-world distance. Hardware-based sensors (e.g., present in a mobile electronic device) may allow for a fast low-power determination of distances. In one embodiment, one or more telemetry-related sensors may be incorporated into a device. For example, data detected by a frequently-calibrated integrated accelerometer may be used to determine a tilt of the device. A device height may be estimated based on empirical data or based on a time difference between a signal (e.g., a sonar signal) emitted towards the ground and a corresponding detected signal. A triangulation technique may use the estimated tilt and height to estimate other real-world distances (e.g., from the device to an endpoint or between endpoints).

  • Patent number: 8838410
    Abstract: Position information of a first sensor unit and a second sensor unit is calculated using angle information of peaks calculated from a light amount distribution having a plurality of peaks detected by light-receiving unit of the second sensor unit from light emitted by light-emitting unit of the first sensor unit. The coordinates of a pointed position are calculated based on the position information of the first sensor unit and the second sensor unit and a change in a received light amount distribution that occurs due to a pointing to a coordinate input region detected by the light-receiving units. Here, the light-emitting units of the respective multiple sensor units are arranged in known positions relative to the light-receiving units.

  • Patent number: 8823543
    Abstract: Non-contacting means of measuring the material velocities of harmonic acoustic telemetry waves travelling along the wall of drillpipe, production tubing or coiled tubing are disclosed. Also disclosed are contacting means, enabling measurement of accelerations or material velocities associated with acoustic telemetry waves travelling along the wall of the tubing, utilizing as a detector either a wireless accelerometer system or an optical means, or both; these may also be applied to mud pulse telemetry, wherein the telemetry waves are carried via the drilling fluid, causing strain in the pipe wall that in turn causes wall deformation that can be directly or indirectly assessed by optical means. The present invention enables detection of telemetry wave detection in space-constrained situations. The invention also teaches a substantially contactless method of determining the time-based changes of the propagating telemetry waves.

    Abstract: Measuring a distance to a surface while compensating for variations in a transverse position and/or low speed displacement of the instrument. One method includes retrieving a predetermined transversal distance from a longitudinal feature at which to extract a relevant distance; retrieving a distance set; retrieving a position of the longitudinal feature relative to the distance set; extracting a range point at the predetermined transversal distance from the longitudinal feature; adding the extracted point to a longitudinal distance set. In another method, if two sensors are provided with an overlap in the transversal direction, extracting a range point at a predetermined transversal position; adding the extracted range point to a longitudinal distance set; retrieving a pitch angle of the instrument; calculating a local slope of the surface using an overlapping transversal point, the pitch angle and the separation length; calculating a height variation using the local slope and a longitudinal separation.

    Abstract: A LIDAR optical remote sensing system and method analyzes the falling edge profile of a return LIDAR signal that may be indicative of an object or an aerosol cloud, which is generally more diffuse. Using the falling edge profile permits burnthrough to an object that may be obscured by the aerosol cloud. The profile is compared against at least one threshold that may correspond, in various embodiments, to a negative slope of the falling edge, an integrated power under the falling edge, or a range estimate error for varying transmitted power values, varying transmitted pulse lengths and/or varying receiver detector field of view values.

  • Patent number: 8744793
    Abstract: A method and apparatus for dynamically adjusting the level of a response signal from an ultrasound transducer is disclosed. During a calibration phase, a description of a gain profile of a level adjuster is set dependent upon an expected response signal for a type of object to be tested and the description is stored in memory. During a measurement phase for an object under test, a description of a gain profile is selected for the type of the object under test and a gain profile is determined from the selected description. The response signal from the object under test is passed through a level adjuster and the level of the response signal is adjusted dynamically in accordance with the gain profile. The description of the gain profile is selected with reference to an expected response either by operator interaction with a user interface or automatically.
