A virtual racecourse is mapped by uniting digital pictures with GPS and inclinometer data, stored in a recorded course file, presented in distance increments of the racecourse, and accessed for individual and group competition over the internet.

A method is disclosed that includes detecting a change in an inclination at a panel of an electronic device. The panel has a display surface. The method also includes detecting a rotation of the panel from a first orientation to a second orientation. The method also includes automatically redrawing an image displayed at the display surface responsive to the rotation when the change in the inclination of the panel does not exceed a threshold during the rotation.

An automatic celestial navigation system for navigating both night and day by observation of K-band or H-band infrared light from multiple stars. In a first set of preferred embodiments three relatively large aperture telescopes are rigidly mounted on a movable platform such as a ship or airplane with each telescope being directed at a substantially different portion of sky. Embodiments in this first set tend to be relatively large and heavy, such as about one cubic meter and about 60 pounds. In a second set of preferred embodiments one or more smaller aperture telescopes are pivotably mounted on a movable platform such as a ship, airplane or missile so that the telescope or telescopes can be pivoted to point toward specific regions of the sky. Embodiments of this second set are mechanically more complicated than those of the first set, but are much smaller and lighter and are especially useful for guidance of aircraft and missiles. Telescope optics focus (on to a pixel array of a sensor) H-band or K-band light from one or more stars in the field of view of each telescope. Each system also includes an inclinometer, an accurate timing device and a computer processor having access to catalogued infrared star charts. The processor for each system is programmed with special algorithms to use image data from the infrared sensors, inclination information from the inclinometer, time information from the timing device and the catalogued star charts information to determine positions of the platform. Direction information from two stars is needed for locating the platform with respect to the celestial sphere. The computer is also preferably programmed to use this celestial position information to calculate latitude and longitude which may be displayed on a display device such as a monitor or used by a guidance control system. These embodiments are jam proof and insensitive to radio frequency interference. These systems provide efficient alternatives to GPS when GPS is unavailable and can be used for periodic augmentation of inertial navigation systems.

An automatic celestial navigation system for navigating both night and day by observation of K-band or H-band infrared light from multiple stars. A preferred embodiment uses three telescopes with each of the three telescopes rigidly mounted with respect to each other and rigidly mounted on a movable platform such as a ship or airplane with each telescope being directed at a substantially different portion of sky. Telescope optics focuses, onto the pixel array of a sensor, H-band or K-band light from stars in the field of view of each telescope. The system also includes an inclinometer, an accurate timing device and a computer processor having access to cataloged infrared star charts.

A three-dimensional and a two-dimensional GPS unit periodically provide coordinate positions of points on the work machine and are combined with a Kalman filter to produce a point of reference on a work machine. The point of reference is improved by combining the position with an inertial position derived from accelerometer data in another Kalman filter. Additionally, the two-dimensional GPS unit provides a heading that is combined with an inertial orientation derived by the angular rate from a gyroscope in another Kalman filter to produce a precise orientation estimate. Inclinometers provide pitch and roll of the work machine. With the point of reference, orientation estimate, pitch, roll and known geometry of the work machine, the GPS unit calculates the location and orientation of machine components and continuously tracks its movement throughout the mine. Additionally, the accelerometers and gyroscope provide position and orientation when the GPS units are inoperable.

A collision avoidance system for reducing false alerts by estimating the elevation of a target, includes short and long range single-dimensional scanning radar sensors having differing ranges and beam angles of inclination, and a digital fusion processor, and preferably includes a locator device, an inclinometer, and a memory storage device cooperatively configured to further perform trend analysis, and target tracking.

The invention is directed to mainpulator assembly (2) for holding and manipulating a surgical instrument (14) in a telerobotic system. The assembly comprises a base (6) fixable by passive or power driven positioning devices to a surface, such as an operating table, and an instrument holder (4) movably mounted on the base. The instrument holder comprises a chassis (6) and an instrument support (70) movably mounted on the body and having an interface engageable with the surgical instrument to releasably mount the instrument to the instrument holder. A drive assembly (7) is operatively coupled to the instrument holder for providing the instrument with at least two degrees of freedom. The instrument holder is separable from the base and the drive assembly so that the holder can be sterilized. The assembly further includes a force sensing element (52) mounted distal to the holder and the drive assembly for detecting forces exerted on the surgical instrument and providing feedback to the surgeon. The assembly is attached to a remote center positioner (300) for constraining the instrument to rotate a point coincident with the entry incision and an inclinometer (350) for preventing gravitational forces acting on the system's mechanisms from being felt by the surgeon.

A motor grader has a control system in which the manner of controlling the blade position differs depending upon whether the blade is to be moved vertically or is to be maintained at a generally constant level and cross slope. First and second hydraulic valves control the flow of hydraulic fluid to the first and second hydraulic cylinders which raise and lower respective ends of the blade. An inclinometer provides an inclinometer output indicating the inclination of the blade along its length with respect to horizontal. The control system includes a first hydraulic cylinder position sensor for determining the extension of the first hydraulic cylinder. The control system further includes a control that is responsive to a control input specifying the desired height and cross slope of the blade, to the first hydraulic cylinder position sensor, and to the inclinometer output. The control provides valve control signals to the first and second hydraulic valves. The control provides a first valve control signal to the first hydraulic valve in dependence upon a desired height specified by the control input, and the control provides a second valve control signal to the second hydraulic valve in dependence upon the inclinometer output and upon the cross slope specified by the control input. However, when the blade is to be moved upward or downward with the retraction or extension of the first cylinder, the control provides the second valve control signal to the second hydraulic valve in dependence upon the first hydraulic cylinder position sensor such that the second hydraulic cylinder retracts and extends with the first hydraulic cylinder, maintaining the cross slope angle of the blade as a constant.
