1. A multiple object positioning and guiding system, for positioning a first object at a desired position and orientation relative to a second object, comprising:
- a plurality of positional tags affixed to body of said second object at points which define three orthogonal axes of said second object;
an array of positional tag interrogation sensor elements located, external to said first object and said second object, at known reference locations relative to said first object;
each of said positional tag interrogation sensor elements physically configured at said locations which define three orthogonal axes of said array;
a computer operatively configured to compute the distance from each of the said positional tag interrogation sensor elements to each of the said positional tags and, subsequently, to compute the location of each of the said positional tags; and
to compute the position and attitude of the said second object relative to said first object;
an interface operationally configured to communicate the said position and attitude results of the said computer.

9. An automated orientation-determining microscope slide comprising:
-
a microscope slide having an upper surface, a lower surface; at least one positional tag fastened to said upper surface of said microscope slide; a shielding material affixed to said lower surface of said microscope slide, in proximity to said positional tag, whereby said positional tag is obscured when viewed through said lower surface. - View Dependent Claims (10)

11. A method for automatically determining the orientation of a microscope slide comprising the steps of.
obtaining a microscope slide having an upper surface, a lower surface, at least one positional tag fastened to said upper surface of said microscope slide, a shielding material affixed to said lower surface of said microscope slide, in proximity to said positional tag, whereby said positional tag is obscured when viewed through said lower surface; -
preparing and placing specimen on said microscope slide; placing said microscope slide in examining position; interrogating said positional tag with appropriate sensor located so as not to be obscured by said shielding material when said microscope slide has an upward orientation; determining said microscope slide has upward orientation if interrogation is successful.

12. A microscope slide comprising:
-
a substrate; at least one radio frequency identification tag permanently affixed to said substrate, said radio frequency identification tag including non-volatile write-once/read-many memory operatively configured to transmit a radio frequency carrier modulated with data stored in said memory, in response to interrogation signal.
