摘要： A velocity estimation method and system is disclosed. The method may include receiving a location signal indicative of a location of the machine and estimating the velocity of the machine based on a change in the location of the machine over a period of time. The method may further include determining a loss of the location signal, detecting a traction device speed of the machine, and selectively estimating the velocity of the machine based on the traction device speed when the location signal is determined to be lost.

摘要： Systems and methods are disclosed herein to use a vehicle back-up camera as a cost-effective dead-reckoning sensor in satellite-based vehicle navigation systems. Since the back-up camera may already use a display of the navigation system for display, the data from the back-up camera may be easily obtained and integrated into the navigation system. The data from the camera is received by a navigation receiver wirelessly or through a wired connection. The image is processed to determine the speed, heading, turn-rate of the vehicle to aid the satellite-based navigation system if the satellite signals are inadequate. Thus, enhanced vehicle navigation- performance can be obtained without adding new sensors and/or connecting to a vehicle data bus.
摘要翻译：本文公开的系统和方法是使用车载备用摄像机作为基于卫星的车辆导航系统中的成本有效的推算传感器。由于备用摄像机可能已经使用用于显示的导航系统的显示器，所以可以容易地获得来自后备摄像机的数据并将其集成到导航系统中。来自相机的数据由导航接收器无线或通过有线连接接收。如果卫星信号不足，则处理图像以确定车辆的速度，航向，转向率以辅助卫星导航系统。因此，在不添加新的传感器和/或连接到车辆数据总线的情况下，可以获得增强的车辆导航性能。

摘要： A timing circuit receives substantially square wave clock signals and generates sine and cos driving signals therefrom at a predetermined frequency for application to first and second mutually perpendicular Hall effect generators. The output signals from the Hall effect generators are algebraically summed to provide a heading signal, the phase displacement of which with respect to the driving signals, is representaive of the orientation angle between one of the Hall effect generators and magnetic north. A counter is synchronized to begin to count clock pulses at the beginning of each period of the driving signals. A logic circuit is effective to disable the counter when the Count signal therein is representative of the orientation angle. The sine and cos of the Count signal are derived and each is multiplied by a distance signal related to the number of revolutions of a wheel of the vehicle being monitored. The resulting coordinate signals are stored in X and Y registers which are automatically updated when the vehicle approaches transmitters at predetermined locations.

摘要： A position locator or homing device for use by fishermen, divers, etc, includes a view finder for directly observing one landmark and adjustable mirrors for reflecting images of other landmarks into the view finder for simultaneous viewing of three landmarks. The position locator also includes scales for recording the angular position of the reflected landmarks to enable pre-setting the adjustable mirrors at the recorded angle so that the user can subsequently find the position of the previous fix. Hairline indicator pins mounted on swing arms and spaced from the mirrors enable accurate recording of the relative angular position of the reflected landmarks and are employed to subsequently locate the position of the fix.
