Electronic tilt measuring system
First Claim
1. A means for measuring relative tilt of one or more platforms to a nominated datum platform, comprising at least one inclinometer per platform and characterised in that it further comprises:
- a) means to average each inclinometer output over a synchronised time period; and
b) a computer programmed to analyse measured data, calculate tilt angles and relative tilts and display the results.

Abstract
The invention provides an electronic tilt measuring system for measuring the relative tilts of various platforms such as weapons on a ship. The basic system comprises an inclinometer (1) at each platform, a central control and display unit (2) and a computer (4). The output signals from the inclinometers (1) are passed to the central unit (2) and averaged over a synchronized time period to give an average inclination measurement with respect to the gravity vector over the measurement period. The data is then passed to the computer (4) where it is analysed. The computer (4) is programmed to calculate measured tilts and relative tilts and to produce graphical representations of the data.

- 4. A means for measuring relative tilts according to claim 4 characterised in that the means to display the readings at the central control position is a master display unit (MDU) which houses electronic circuits to process each signal and to provide an averaged signal over a set time period, the time period being synchronised for all the inclinometers.

17. A method of measuring relative tilt of one or more platforms to a nominated datum platform comprising the steps of:
-
1) positioning at least one inclinometer on said one or more platforms and at the nominated datum platform; 2) connecting each inclinometer to a central control position; 3) training all the platforms to a common bearing; 4) reading the measured values from each inclinometer at the central control position and averaging each of the measured values over a synchronised time period; 5) entering the readings into a computer; 6) training the platforms to another common bearing; 7) repeating steps
4) to
6) as many times as required;8) analysing the readings by means of a computer program; and 9) displaying or reading the results. - View Dependent Claims (18, 19, 20, 21)
