Abstract: A system for dispensing medication includes a dispensing device unto which a prepackaged cassette can be releasably installed. The cassette contains medication that has been prepackaged in individual pockets along a strip. The strip is wound between a supply reel and a take up reel within the cassette. A control mechanism associated with the dispensing device advances the strip within the cassette by winding the strip onto the take up reel, while unwinding the strip from the supply reel, and while moving a dispensing mechanism also associated with the device into contact with the strip for opening a medication pocket to expel the medication from the strip and out of the cassette.

Abstract: A dispensing device for medication that has been prepackaged in individual pockets along a strip includes a first holder for securing one end of the strip and a second holder for securing the opposite end of the strip. A drive mechanism advances the strip along a predetermined path leading from the first holder, through a dispensing mechanism and to the second holder. The dispensing mechanism has a first assembly that moves into contact with the strip and opens a medication pocket. A second assembly presses against the strip as it is further advanced to expel the medication from the opened pocket.

Abstract: A device for producing a digital representation of an analog signal in apparatus for use in analyzing samples of biological material. The apparatus conducts such analysis by optical techniques, whereby an analog signal is generated which corresponds to the strength of a light component impinging a light responsive element.

Abstract: A motor control system for use in a high speed teleprinter or the like for controlling the rotational position and movement of a rotor, and apparatus driven by the rotor, by detecting back EMF induced into an unenergized field winding by rotational movement of the rotor. The output and input terminals of a first amplifier responsive to a first motor control signal, and a second amplifier responsive to a second motor control signal, are reactively coupled such that the amplifiers respond to either motor control signal to develop a signal simulating the signal into an unenergized winding of the motor due to mutual inductance with an energized winding. A differential voltage comparator provides a feedback signal indicative of motor performance upon comparing the simulated signal with the signal actually induced.
