Abstract: 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 ? degrees can be added with a different angle ? to X sensors when additional horizontal and magnetic coverage is desirable.

Abstract: A current Ibe and a voltage Vbe before a large current discharge in a secondary battery are stored in a memory. Plural voltage-current pairs are detected and stored in the memory during the large current discharge. Next, a regression curve (or a regression line) is obtained based on the plural voltage-current pairs stored in the memory using a well-known method. A discharge current Ip which exceeds a current-sensor detectable range is input in the regression curve to obtain a voltage Vp. A maximum discharge coordinate is set using the discharge current Ip and the voltage Vp. An internal resistance Rin of the secondary battery is calculated based on an inclination of a line that connects the coordinates (Ibe, Vbe) and (Ip, Vp).

Abstract: Fixed bond information is derived. A fixed bond representation of a chemical structure is derived from a delocalized representation. A path is conceptually traced through the represented structure and an examination is conducted, for each atom, of each possible electronic and bonding state that is consistent with what has come before along the path. A result is found by extensively or exhaustively examining all possible states and orders in a semi-recursive procedure that is directed early towards likely answers. If there is more than one possible solution, the best solution is chosen by use of a rating function.

Abstract: An integrity management system predicts abnormalities in complex systems before they occur based upon the prior history of abnormalities within the complex system. A topology of the nodes of a complex system is generated and data is collected from the system based on predetermined metrics. In combination with dynamic thresholding, fingerprints of the relevant nodes within a complex system at various time intervals prior to the occurrence of the abnormality are captured and weighted. The fingerprints can then be applied to real-time data provide alerts of potential abnormality prior to their actual occurrence.
