Abstract:
A device for measuring the angle of orientation with respect to a known frame of reference between a first object having a first axis and a second remote destination, said device comprising:a first arm member defining a first longitudinal axis and an object engaging surface substantially parallel to said first longitudinal axis for engaging a first object thereagainst; a second arm member connected in pivotal relation to said first arm member at a primary joint for pivotal movement about a first transverse pivot axis intersecting said first longitudinal axis and defining a second longitudinal axis intersecting said first longitudinal axis and said first transverse pivot axis; a laser mounted on said second arm member for projecting a laser beam along a laser beam axis parallel to said second longitudinal axis; and, first angle measuring means mounted on said second arm member to measure and indicate the angle of said second longitudinal axis with respect to a fixed reference frame other than said first longitudinal axis, wherein said first angle measuring means also indicates the complement of said angle of said second longitudinal axis with respect to a fixed reference frame other than said first longitudinal axis.
