1. A method of delivering a substance into an eye comprising:
- recognizing a connection between a tip segment and a limited reuse assembly;
receiving dosage information from the tip segment;
activating a temperature control device to alter a temperature of a substance to be delivered into an eye;
receiving temperature information from a thermal sensor;
using the temperature information to control the temperature control device;
receiving an input indicating that the substance is to be delivered; and
based on the dosage information, controlling an actuator to move a plunger to deliver the substance.

19. A method of delivering a substance into an eye comprising:
-
recognizing a connection between a tip segment and a limited reuse assembly;
identifying a type of tip segment connected to the limited reuse assembly;
receiving dosage information from the tip segment;
activating a temperature control device to alter a temperature of a substance to be delivered into an eye;
receiving temperature information from a thermal sensor;
using the temperature information to control the temperature control device;
moving an actuator shaft to a homed position;
before the substance is injected into an eye, moving the actuator shaft so that a mechanical linkage interface contacts a plunger interface;
receiving an input indicating that the substance is to be delivered;
after the substance has reached the proper temperature, using the dosage information to control the actuator to move the plunger to deliver the substance into an eye;
receiving data from a displacement sensor indicating a distance that an actuator shaft has moved; and
providing an indication of the dosage delivered based on the distance. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31)
