CONTROLLING A MOTOR OF AN INJECTION DEVICE
First Claim
Patent Images
1. A method comprising:
- receiving a signal from a force sensor, the signal representing a force that is applied by a motor of an injection device to a plunger of a cartridge; and
causing a current that is required to enable the motor to apply the force represented by the signal from the force sensor to the plunger, incremented by a predetermined value, to be applied to the motor.

Abstract
In order to improve the energy efficiency of an injection device 100, a current is caused to be applied to a motor 113 of the injection device 100, which is related to a signal from a force sensor 115. The signal represents a force that is applied by the motor 113 to a plunger 122 of a cartridge 121.
