Patent number: 11975960Abstract: A method and computer program product for defining a PWM drive signal having a defined voltage potential. The PWM drive signal has a plurality of “on” portions and a plurality of “off” portions that define a first duty cycle for regulating, at least in part, a flow rate of a pump assembly. At least a portion of the “on” portions of the PWM drive signal are pulse width modulated to define a second duty cycle for the at least a portion of the “on” portions of the PWM drive signal. The second duty cycle regulates, at least in part, the percentage of the defined voltage potential applied to the pump assembly.Type: GrantFiled: May 30, 2023Date of Patent: May 7, 2024Assignee: DEKA Products Limited PartnershipInventors: Russell H. Beavis, James J. Dattolo

Patent number: 11596732Abstract: A method of dispensing fluid includes three processes. A first one of these processes includes pumping fluid into a resilient variable-volume dispensing chamber. The dispensing chamber is in series with a normally present finite fluid impedance and an output. The impedance is sufficient so as to cause expansion of the dispensing chamber as it receives pumped fluid even while some fluid flows through the output. Another one of these processes includes repeatedly measuring a parameter related to volume of the dispensing chamber over time. A third one of these processes includes controlling the pumping of fluid based on repeated measurements of the parameter to produce a desired fluid flow through the output. A corresponding system for dispensing fluid implements these processes.Type: GrantFiled: August 19, 2019Date of Patent: March 7, 2023Assignee: DEKA PRODUCTS LIMITED PARTNERSHIPInventors: Dean Kamen, Russell H.
