Abstract: A message processing facility is described. The facility receives user input defining a textual message intended for an addressee service principal. Before sending the defined textual message, the facility analyzes the defined textual message to determine a textual message category to which the defined textual message belongs among a plurality of textual message categories.

Abstract: A facility for causing the refill of prescriptions is described. The facility conducts a conversational exchange with a person. From the exchange, the facility discerns (1) an intent of refilling a prescription, and (2) an identification of a prescription to be fulfilled. In response to this discerning, the facility causes a pharmacy refill order to be placed on behalf of the person for the identified prescription.

Abstract: An automated knife change adjustment on dual-gearbox paper cutting machines employs servo motors driving, with great gear reduction, turnbuckle nuts on a pair of pull arms. A graphic user interface automatically controls the knife adjustment on a replacement knife, the interface computer being connected to position sensors for the knife, to main motors driving gearboxes that cycle the knife down and up, to the servo motors and other sensors. The system avoids tedious manual steps typically in setting a replacement cutting knife to a correct cutting position.

Abstract: A method for counting conveyed workpieces, such as on a variable speed conveyor belt, includes sensing interruptions via an object sensor such as an optical sensor with a light beam, and with a computer, applying a mathematical comparison between duration of interruptions to the light beam path and gaps that separate these interruptions. The comparison determines which interruptions are caused by the passage of conveyed workpieces and which interruptions are caused by the passage of other objects such as components of the conveyor belt. The method described involves the selection of a preset factor used in a ratio comparison between the duration of interruptions to the light beam and the gaps that separate these interruptions such that the computer is able to accurately count objects such as sheets of paper pulled by gripper bars and distinguishing between sheets of paper and gripper bars such that gripper bars and clips are not incorrectly counted as sheets of paper.

Abstract: A system for accurately controlling the start and stop positions for operations on conveyor-moved products, such as for applying glue lines, perforations or slits on sheets of paper, uses product position rather than timing to accurately control "on" and "off" operation positions on the product. The entry of a sheet of paper, for example, onto the conveyor path is noted by detecting the leading edge of the paper moving past an optical sensor. The location of the sheet is always known in a computer, due to conveyor position information continually fed to the computer. Distances which will be involved in the compensation times for the operating devices (e.g.

Abstract: An infinitely adaptive motor control positioning system is disclosed which uses a calculated variable velocity curve while tracking deceleration and acceleration before and after application of a power pulse so as to anticipate movement for continuing adjustable power cycles. This enables the system to optimize positioning accuracy and minimize elapsed time positioning a driven mechanism. Up to seven phases of drive occur in any positioning move. Each phase consists of drive cycles when the motor receives power (and thus accelerates) and then is void of power (and thus decelerates). During each drive cycle, different sets of equations are implemented to calculate an "ideal speed" based upon the system response, actual speed, previously used power, and the distance still required to reach the target.

Abstract: A method and apparatus for electrodeposition of insulating coatings such as photoresists having uniform thickness throughout the coating. The apparatus comprises one or more cathodes disposed in a bath containing an electrophoretic depositing composition, one or more anodes disposed in said bath in face to face relationship with the cathode, and means for applying a voltage between the anode and the cathode to produce a current whereby a current density gradient is formed on the cathode, the gradient comprising high and low current density areas. The anode of the present invention is configured so that the anode is concentrated opposite the high current density areas of the cathode, thereby controlling the thickness of deposition by controlling the amount of current flowing to the cathode.
