Ancillary arrangement for inclusion in a distance measuring instrument
First Claim
1. An ancillary arrangement for application with a distance measuring instrument means when setting out boundary marks, the distance measuring instrument being of a type which includes an electronic distance meter, a vertical angle meter (18) and a horizontal angle meter (19), a signal processing and computing unit (16, 16'"'"') which computes a position of a measuring reflector (12) in relation to the instrument, and input means (17) for input of the desired boundary settings of an area of ground into a memory location of a memory store in said computing unit prior to setting out said boundary, wherein the distance measuring instrument is adapted to be held directed towards the reflector and to carry out repeated measurements thereon;
- wherein the computing unit (16) is constructed to ascertain with each measuring operation whether measuring data obtained coincides or deviates from setting-out data within a predetermined acceptable tolerance range, and when deviation is observed to compute the direction or directions in which the reflector must be moved in order to be positioned in a location determined by said setting-out data and to provide movement direction signals; and
comprising an indicator which is steered by said movement direction signals produced by the computing unit so as to produce continuously on the basis of said signals a clearly discernible indication of a code which can be readily understood during a working procedure by a person placed adjacent the reflector and which indicates whether the position of the reflector is to be moved, and if so, in which direction.

Abstract
The present invention relates to an arrangement for coaction with a distance measuring instrument in the setting out of boundaries or like demarcations. The distance measuring instrument includes an electronic distance meter, a vertical angle meter (18) and a horizontal angle meter (19), a signal processing and computer unit (16, 16'"'"') which computes the position of a measuring reflector (12) in relation to the instrument, and an input means (17) for input of desired setting-out data for an area of land into a memory location in the computer prior to a setting-out operation. The distance measuring instrument is held directed towards the measuring reflector and repeatedly makes measurements thereon. With each measuring occasion, the computer unit (16) ascertains whether or not the data obtained lies within a predetermined, acceptable tolerance range in relation to the setting-out data. If the measured data lies outside this range, the computer establishes how the reflector should be moved in order to be located within the tolerance range. An indicator is controlled by the movement signals produced by the computer unit and in response to these signals continuously gives to a person positioned adjacent the reflector a clear, discernible indication of whether the reflector shall be moved, and if so, in which direction or directions, or if the reflector should be left as it is.
