Patent number: 9625612Abstract: Systems and methods for identifying prominent landmarks in a geographic area are provided. More particularly, geographic imagery data, such as panoramic images captured by a camera from a perspective at or near ground level, can be analyzed to identify landmarks depicted in the geographic imagery data. For instance, structure-from-motion techniques can be used to generate a point cloud of tracked features that are located a threshold distance away from one or more camera perspectives associated with the geographic imagery data. Landmarks that are visible from multiple camera perspectives and that are visible from greater distances relative to one or more camera perspectives can be identified as prominent landmarks in a geographic area. A geographic information system can use the prominent landmarks for a variety of purposes, such as for use in providing travel directions, for rendering landmarks in an emphasized style, and/or for constructing/displaying a three-dimensional model of the landmark.Type: GrantFiled: September 9, 2013Date of Patent: April 18, 2017Assignee: Google Inc.Inventors: Brian Edmond Brewington, Bryan M.

Patent number: 9625556Abstract: An impedance synthesis method for single and multi-probe high resolution slide screw impedance RF and microwave tuners employs a fast calibration algorithm, which creates appropriately distributed calibration points over the Smith chart and a second order interpolation algorithm between calibration points, optimized for best suitability to the natural behavior of the tuners. The fast tuning algorithm uses a general search in order to identify the closest calibrated points, followed by a gradient search using fine interpolation grid in order to reach the final target. The method is applicable, after proper data preparation, also to double and triple probe harmonic tuners. The method allows tuning accuracy as high as ?60 dB, or deviation-from-target vector distance of 0.001 units on the Smith chart, whereas absence of the fine grid interpolation typically yields accuracies of the order of ?20 dB, or a deviation-from-target vector distance of 0.1 reflection factor units.Type: GrantFiled: February 7, 2011Date of Patent: April 18, 2017Inventor: Christos Tsironis

Patent number: 9470554Abstract: A position detector includes a Hall element that detects a magnetic flux density and a temperature detection element that detects the temperature of the Hall element. In a rotation angle calculation process, a temperature correction value a is calculated by substituting a detection temperature t of the temperature detection element and a reference maximum voltage V0 at a reference temperature t0 for a=V0×k (t?t0). Next, a correction maximum voltage Vt is calculated by substituting the temperature correction value a for a temperature characteristic formula of Vt=V0+a. Further, a rotation angle ? of a magnet relative to the Hall element is calculated by substituting an output voltage VH of the Hall element and the correction maximum voltage Vt for ?=sin?1 (VH/Vt). Since the correction maximum voltage Vt is corrected according to the temperature, the rotation angle is accurately detected.Type: GrantFiled: July 29, 2013Date of Patent: October 18, 2016Assignee: DENSO CORPORATIONInventors: Takamitsu Kubota, Akitoshi Mizutani, Yoshiyuki Kono
