    摘要: The instant invention utilizes two, optionally orthogonal and optionally slightly tilted, horizontal magnetic sensors and, optionally, a 2 or 3 axis accelerometer or inclinometer to calculate a pitch, roll and tilt compensated heading. A vertical, Z, component is relatively constant compared to X and Y components, the Z component can be abstracted from the X and Y sensor when pitch and roll is applied based on Z offset measured with X or Y sensor at high tilt angles. Additional sensors tilted at various θ degrees can be added with a different angle α to X sensors when additional horizontal and magnetic coverage is desirable.

    摘要: The instant invention discloses a method for an orientation measuring instrument to isolate and separate gravitational and non-gravitational components of acceleration from accelerometer measurements by using an ambient magnetic field, typically the earth's magnetic field, as a fixed rotation reference. Using magnetic field measurements, one can track changes in orientation of a device and use that information to determine the gravitation direction, during periods when acceleration measurements include non-gravitational acceleration combined with gravitational acceleration components. In addition to determining orientation, a method and associated instrument provide a non-gravity acceleration vector of the device.

    摘要: Methods, apparatuses and systems of providing control of display content on a display with a device are disclosed. One method includes establishing a fixed reference on the display. A user input is received indicating that the device is at a user selected position corresponding to the fixed reference and capturing a position of the device in order to establish a corresponding reference position. The display content on the display is determined based on measured displacement of the device relative to the established reference position.

    摘要: A method and system for an interactive controller device comprising a two axis sensor in combination with one or more other sensors for hand-held devices operated in mid-air. A time sequence of measurements in three linearly independent directions is used to extract the angles of rotation around one or more distinct axes. A method is disclosed to approximately determine a transformation matrix, T, of a device orientation from a sequence of single vector measurements as a combination of rotations about specified axes. Calculated rotation angles can then be used to calculate changes in a controller or pointer position and a rate change thereof.

    摘要: A book holder utilizing an "L" shaped swinging-assembly as an adjustable support for the bottom of a book. The assembly can be swung out to adjust for thick books, and it automatically swings back to the correct position under the influence of gravity. A spring loaded page retainer presses the pages open, and the page retainer can be rotated down out of the path of the pages so that the pages can be turned. The page retainer stays down to allow for flipping through pages of a book.
