Title: Living body action current source estimating method
Inventor: SHIBATA KENJI
IPC: A61B6/03
Filed: 1991-09-27
Abstract: PURPOSE:To improve the estimation accuracy of a living body action current source, while decreasing the calculation quantity. CONSTITUTION:By collecting magnetic field data of a current source set in a living body, and deriving the minimum square average error to measured data, a position of a current source is estimated roughly. By deriving a cube Ri (obj) in which the estimated position is the apex, magnetic field data formed by a current source Fijk in an arbitrary position of the inside of the cube Ri (obj) is calculated. In this case, by deriving a correction matrix of collection data and calculation data in the apex of the cube Ri (obj), and interpolating it, a correction matrix in the inside of the cube Ri (obj) is derived. By allowing the correction matrix to work on the calculated magnetic field data, an error caused by calculating a numerical value is corrected. By deriving the minimum square average error of the corrected magnetic field data and the measured data, a final current source is estimated.

Filed: 1990-10-17
Abstract: PURPOSE:To enable an inspection sequence setting time be shortened by serially determining an inspection sequence while sequentially obtaining nearest distant steps after the definition of a step corresponding to the first inspection part. CONSTITUTION:A plurality of measurement points corresponding to every part on an inspected circuit board are grouped as one step, and an inspection first step as a probe start point is determined by an inspection first step determination means 42. A nearest step detection means 44 obtains a distance indicated with maximum axis component data for every probing step, using a step having a newly determined inspection turn as a reference step, and the longest distance obtainable therefrom determines the shortest probing step as the next inspection object. Also, steps for the nearest distance are serially obtained until a step with an uncertain inspection turn disappears via an inspection sequence setting control means 46. The inspection sequence is thereby determined serially and written in memory 36, thereby enabling the final inspection sequence to be established.
