INFUSION DEVICES WITH DISTRIBUTED MOTOR CONTROL AND RELATED OPERATING METHODS
First Claim
1. An infusion device comprising:
- a motor operable to deliver fluid to a body of a user;
a first control module; and
a second control module coupled to the first control module, the first control module enabling input power for the motor in accordance with a handshaking sequence of communications between the first control module and the second control module and providing a dosage command to the second control module, the second control module operating the motor using the input power based at least in part on the dosage command in accordance with the handshaking sequence of communications.

Abstract
Infusion systems, infusion devices, and related operating methods are provided. An exemplary infusion device includes a motor operable to deliver fluid to a body of a user, a first control module, and a second control module. The first control module and the second control module are coupled to one another. The first control module enables input power for the motor in accordance with a handshaking sequence of communications between the first control module and the second control module and provides a dosage command to the second control module, with the second control module operating the motor using the input power based on the dosage command in accordance with the handshaking sequence of communications.

15. A method of operating a motor of an infusion device, the method comprising:
-
enabling, by a first control module of the infusion device, input power from an energy source to a driver module coupled between the energy source and the motor in accordance with a first sequence of communications between the first control module and a second control module of the infusion device; after enabling the input power, enabling, by the second control module, output power from the driver module to the motor in accordance with a second sequence of communications between the first control module and the second control module; and after enabling the output power from the driver module, operating the driver module to provide the input power to the motor in accordance with a third sequence of communications between the first control module and the second control module. - View Dependent Claims (16, 17, 18, 19, 20)
