Abstract
Official abstract text for this publication.
Disclosed herein is a digital sight for a manually-portable shell-firing mortar. The digital sight includes a first accelerometer, a second accelerometer arranged perpendicular to the first accelerometer, a gyroscope arranged perpendicular to the first and second accelerometer, and a controller configured to calculate and display a re-firing direction varied from a primary-firing direction, using the first and second accelerometers and the gyroscope.
First claim
Opening claim text (preview).
What is claimed is: 1 . A digital sight for a manually-portable shell-firing mortar, comprising: a first accelerometer; a second accelerometer arranged perpendicular to the first accelerometer; a gyroscope arranged perpendicular to the first and second accelerometers; and a controller configured to calculate and display a re-firing direction varied from a primary-firing direction, using the first and second accelerometers and the gyroscope, wherein the first and second accelerometers are configured to measure acceleration of the mortar that is being rotated about one end of the mortar fixed to the ground when the mortar fires a shell. 2 . The digital sight for a manually-portable shell-firing mortar according to claim 1 , wherein the gyroscope is configured to enable the first and second accelerometers measuring the acceleration to be positioned perpendicular to the gyroscope when the mortar fires a shell. 3 . The digital sight for a manually-portable shell-firing mortar according to claim 1 , wherein the controller is configured to calculate the re-firing direction by calculating rotational displacement of the barrel using the measured acceleration. 4 . The digital sight for a manually-portable shell-firing mortar according to claim 1 , wherein the controller is configured to calculate the re-firing direction by calculating rotational displacement of the barrel using linear acceleration of the mortar obtained by gravity, high-frequency noise, and a shock applied to the mortar. 5 . The digital sight for a manually-portable shell-firing mortar according to claim 1 , wherein the controller comprises a gyro-signal processing board, a first accelerometer-signal processing board, a second accelerometer-signal processing hoard, a wired/wireless communication board, an antenna, and a central processing board.
