380 results about "Relative direction" patented technology

The most common relative directions are left, right, forward(s), backward(s), up, and down. No absolute direction corresponds to any of the relative directions. This is a consequence of the translational invariance of the laws of physics: nature, loosely speaking, behaves the same no matter what direction one moves. As demonstrated by the Michelson-Morley null result, there is no absolute inertial frame of reference. There are definite relationships between the relative directions, however. left and right, forward and backward, and up and down are three pairs of complementary directions, each pair orthogonal to both of the others. Relative directions are also known as egocentric coordinates.

Method and apparatus for reordering data items

A swapping utility enables directional commands from a graphic user interface and / or keyboard to be utilized to swap data items associated with lists, tables or other series of data items. Upon receipt of both a directional command, e.g. up, down, left, or right, and a swap command, the utility uses the current position of the cursor or a selected entity to identify a first data item to be swapped and the relative direction thereto to identify a second, adjacent data item to be swapped. If both identified data items are of the same data type, their respective contents are exchanged within the ordered list or table without the need to cut and paste the content. In alternative embodiments, multiple adjacent data items may be swapped, or, in an embodiment which utilizes multiple selection icons, single or multiple nonadjacent entities may be directly swapped.

Apparatus and method for determining the relative position and orientation of neurostimulation leads

Interelectrode impedance or electric field potential measurements are used to determine the relative orientation of one lead to other leads in the spinal column or other body / tissue location. Interelectrode impedance is determined by measuring impedance vectors. The value of the impedance vector is due primarily to the electrode-electrolyte interface, and the bulk impedance between the electrodes. The bulk impedance between the electrodes is, in turn, made up of (1) the impedance of the tissue adjacent to the electrodes, and (2) the impedance of the tissue between the electrodes. In one embodiment, the present invention makes both monopolar and bipolar impedance measurements, and then corrects the bipolar impedance measurements using the monopolar measurements to eliminate the effect of the impedance of the tissue adjacent the electrodes. The orientation and position of the leads may be inferred from the relative minima of the corrected bipolar impedance values. These corrected impedance values may also be mapped and stored to facilitate a comparison with subsequent corrected impedance measurement values. Such comparison allows a determination to be made as to whether the lead position and / or orientation has changed appreciably over time. In another embodiment, one or more electrodes are stimulated and the resulting electric field potential on the non-stimulated electrodes is measured. Such field potential measurements provide an indication of the relative orientation of the electrodes. Once known, the relative orientation may be used to track lead migration, to setup stimulation configurations and parameters for nominal stimulation and / or navigation. Also, such measurements allow automatic adjustment of stimulation energy to a previously-defined optimal potential field in the case of lead migration or postural changes.

Determining the direction of travel of an automotive vehicle from yaw rate and relative steering wheel angle

A method of using relative steering wheel angle of an automotive vehicle, vehicle yaw rate, and vehicle speed to determine whether the vehicle is traveling forward or backward. Forward and backward steering wheel angles are calculated from vehicle speed and yaw rate (22). A difference between relative steering wheel angle and forward steering wheel angle (10), and a difference between relative steering wheel angle and backward steering wheel angle (12) are calculated. The difference between relative steering wheel angle and forward steering wheel angle is filtered (14), and a difference between the filtered and the unfiltered difference between relative steering wheel angle and forward steering wheel angle is calculated to obtain a forward net difference (18). The difference between relative steering wheel angle and backward steering wheel angle is filtered (16), and a difference between the filtered and the unfiltered difference between relative steering wheel angle and backward steering wheel angle is calculated to obtain a backward net difference (20). While repeatedly performing the foregoing steps, forward net difference values derived from the forward net differences are accumulated (24), and backward net difference values derived from the backward net differences are accumulated (26). The travel direction is determined by comparing the accumulation of forward net difference values and the accumulation of backward net difference values (28). Absolute steering wheel angle and road bank angle can also be calculated.
