Intelligent pump system
TLDR
In this paper, the benefits of variable frequency drive (VFD) technology more accessible to pump users are discussed, including protection, reliability, and ease of use not possible with other variable frequency drives.Abstract:
The present invention is a controller specifically for pumps, making the benefits of variable frequency drive (VFD) technology more accessible to pump users. The present invention incorporates pump-specific system optimization software, an industrial grade drive, and a menu-driven user interface, offering protection, reliability, and ease of use not possible with other variable frequency drives.read more

Pump controller system and method
TL;DR: In this article, a method and apparatus for a pump control system is described, which can perform self-calibrating procedure, provide precise motor speed control, provide a limp mode before shutting down the motor when system parameters are exceeded and/or fault conditions occur, detect fault conditions, and can store fault conditions for later retrieval.
Patent
Correction factor testing using frequent blood glucose input
TL;DR: In this paper, an apparatus comprising a user interface configured to generate an electrical signal to begin determination of an effective correction factor when prompted by a user, an input configured to receive sampled blood glucose data of a patient that is obtained during a specified time duration, including a time duration after delivery of an initial insulin correction bolus, and a controller in electrical communication with the input and the user interface is described.
