Abstract: The system disclosed here includes a computer-implemented patient therapy management and coaching system, a database system to collect and maintain patient data associated with a plurality of medical device users that includes a trainee patient assigned to a coach, and a user device communicatively coupled to the patient therapy management and coaching system and associated with the coach. The management and coaching system is operative to: receive a patient request for coaching; process the request to automatically identify goals to be achieved by the trainee patient; communicate the goals to the coach's user device; receive an accepted goal selected from the identified goals; create a patient coaching program for the accepted goal; generate insight messages based on patient data collected for the trainee patient, the generated insight messages related to the patient coaching program; and deliver the generated insight messages to the user device associated with the coach.

Abstract: A d.c. high voltage operational amplifier. The output of a conventional power operational amplifier is converted to a.c. which is stepped up by a transformer and then rectified to provide a high voltage d.c. output. Appropriate feedback circuitry is utilized to stabilize the overall operational amplifier against oscillation and provide substantially perfect linearity between the input and output voltages of the high voltage operational amplifier when incorporating negative feedback.

Abstract: This invention relates to a method and apparatus for measuring the exposure variation in the cross scan direction in an optical projector and scanning apparatus of the type that uses an annular aperture or slit. This measuring is achieved by measuring the light intensity from point to point along the arcuate illuminated area. Where the illuminated area is tapered so as to accommodate a pivoting carriage the system of this invention processes the intensity signal to yield a uniformity signal that only indicates departures from the ideal.

Abstract: A stepping motor control circuit permitting selective operation of the motor in various modes such as half or full step mode. The circuit includes a pulse generator producing pulses at a selected motor step rate. A switch means selects the step size while a second switch selects the motor direction. An up/down counter counts pulses from the pulse generator in a direction correlated with the selected rotation direction. A read-only-memory is addressed as a function of the periodically repeating count in the up/down counter and the selected step size. The stored information at the addressed read-only-memory location actuates motor drive circuitry which generates energizing signals for the motor windings to drive the motor in the selected direction a distance corresponding to the selected step size at a step rate equal to the pulse rate of the pulse generator.
