DFM presents a critical comparison of telescope drive technologies!
Dr. Frank Melsheimer investigates various drive technologies and discusses the advantages, disadvantages, and
performance of gear systems used to drive a telescope.
Criteria, such as positioning and tracking, stiffness, smoothness, gear ratio, gear efficiency, backlash, periodic
error and cost is evaluated for multiple gear configurations to determine performance ratings.
An analytical example of a metal band drive is presented to show its lack of stiffness compared to gear and

DFM delivers a gimbal to a Department of Energy Laboratory one week early!
In September 2004, DFM Engineering was awarded a contract to provide a gimbal to a laboratory of the US Department
of Energy. The gimbal will support instruments developed by the laboratory for performing various field measurements.
One of the primary concerns of the customer was ease of use and programming. A users interface and command program
was provided which communicates with the gimbal control software.
The source code for the user interface command program allows the customer to easily write their own command
program incorporating any special features they need. The command program may be used to perform powerful motions
including a user defined raster scan.
The gimbal was shipped one week early in spite of the Christmas holidays.
