Abstract: An improved method for producing a medical device, such as a prosthetic or orthotic structure is disclosed which makes the procedure more widely available at less cost. The method involves making a model (56) of the body part for which a medical structure is to be manufactured using a conformable fabric impregnated with a settable resin. The model (56) may be prepared (20 ) by a physician or a prosthetist who has no direct access to an expensive digitizing scanner. The model (56) is removed (24) from the patient's body part and shipped to a scanning facility (12) where a digitizing scanner (50) is used to produce (26) a digitized image (60) of the model (56). The digitized image (60) is shrunk to compensate for the thickness of the model (56) and the digitized data file is preferably sent back to the physician or prosthetist who manipulates (28) the digitized image (60) using a customized software program to produce (28) a modified data file. The modified data fil e is sent to the scanning facility (12) where the modified data file is converted (34) into control code for a machine which produces (38) a mold us ed in the manufacture of the medical device. The mold may be manufactured at th e scanning facility (12) or the modified data file may be uploaded to the manufacturing facility (14) which may manufacture the mold as well as the medical device. The method is also adapted for use in producing many other medical or anthropometric devices which requires a comfortable precision fit to the human body. The advantage is making this valuable medical service mor e widely available at reduced cost, and more efficiently utilizing expensive equipment to reduce the unit cost of medical and anthropometric devices.</SD OAB>

Abstract: A primer system for agricultural product distribution machines, such as an agricultural air seeder, a precision planter, a sprayer, or the like, includes a tank or a bin for holding the product, a distribution system for conveying and distributing the product from the tank and a driving mechanism for driving the product from the tank into the distribution system at a certain rate. The driving mechanism can run automatically or can be selectively operated, based on commands received from a microcontroller. The microcontroller may receive signals from a user interface and from sensing equipment, such as a ground speed detector, a pressure sensor, a flow metre, or the like. In a regular mode of operation, the controller runs the driving mechanism automatically at a rate calculated based on the signals received from the above mentioned systems. Most agricultural machines have the automated mode of operation of the driving mechanism, conditioned by the ground speed of the tractor being higher than a minimum speed. A bypass mode of operation of the driving mechanism can be selected by pressing a primer button on the user interface. The primer button triggers a bypass signal, instructing the microcontroller to run the driving mechanism at a predetermined dispensing rate, regardless of other factors, such as the detected ground speed. The bypass mode of operation could also be activated upon reception, at the microcontroller, of bypass signals from sensors such as an implement height detector, determining the height of an implement of the agricultural product distribution machine relative to the ground.
