Publication number: 20140046260Abstract: A wearable infusion pump assembly includes a reservoir for receiving an infusible fluid, and an external infusion set configured to deliver the infusible fluid to a user. A fluid delivery system is configured to deliver the infusible fluid from the reservoir to the external infusion set. The fluid delivery system includes a volume sensor assembly, and a pump assembly for extracting a quantity of infusible fluid from the reservoir and providing the quantity of infusible fluid to the volume sensor assembly. The volume sensor assembly is configured to determine the volume of at least a portion of the quantity of fluid. The fluid delivery system further includes a first valve assembly configured to selectively isolate the pump assembly from the reservoir, and a second valve assembly configured to selectively isolate the volume sensor assembly from the external infusion set.Type: ApplicationFiled: July 29, 2013Publication date: February 13, 2014Applicant: DEKA PRODUCTS LIMITED PARTNERSHIPInventors: Dean Kamen, Larry Brian Gray, Richard J. Lanigan, John Matthew Kerwin, Stephen Lewis Fichera

Publication number: 20130268095Abstract: A prosthetic arm apparatus including a plurality of segments that provide a user of the prosthetic arm apparatus with substantially the same movement capability and function as a human arm. The segments are connectable to one another and connectable to a prosthetic support apparatus that may be adorned by the user. Each segment of the plurality of segments provides a portion of the movement capability, enabling the plurality of connected segments connected to the harness mount to provide substantially the same movement capability as that lacking in the user.Type: ApplicationFiled: May 24, 2013Publication date: October 10, 2013Applicant: DEKA Products Limited PartnershipInventors: Christopher O. Evans, N. Christopher Perry, Dirk Albertus van der Merwe, Christopher C. Langenfeld, John Matthew Kerwin, Stewart M. Coulter, Stanley B. Smith, III, Keith David Violette, Steven W. Nickson, Thomas S.

Publication number: 20110264238Abstract: A control system for control of a prosthetic device having a plurality of actuators receives an orientation signal indicative of a desired movement. The control system evaluates whether the prosthetic device may move as desired with a current angle of rotation and commands at least one actuator to move the prosthetic device as desired by maintaining the current angle of rotation or by adjusting the angle of rotation if the prosthetic device cannot move as desired with the current angle. The control system may alternate between commanding a first subset of actuators and a second subset of actuators each time the orientation signal is indicative of a neutral position. The control system may include a position sensor and a compliance sensor and may command at least one actuator based on a combination of positional control using the position sensor and force control using the compliance sensor.Type: ApplicationFiled: April 15, 2011Publication date: October 27, 2011Applicant: DEKA Products Limited PartnershipInventors: Dirk Albertus van der Merwe, Gregory Randall Lanier, JR., John Matthew Kerwin, Gerald Michael Guay, N.

Publication number: 20100268351Abstract: A system for control of a prosthetic device includes at least one Inertial Measurement Unit detecting orientation of a user's foot. The at least one Inertial Measurement Unit is in communication with a device module configured to command at least one actuator of a prosthetic device. The at least one Inertial Measurement unit sends output signals related to orientation of the user's foot to the device module and the device module controls the at least one actuator of the prosthetic device based on the signals from the at least one Inertial Measurement Unit.Type: ApplicationFiled: February 16, 2010Publication date: October 21, 2010Applicant: DEKA Products Limited PartnershipInventors: Dirk Albertus van der Merwe, Gregory Randall Lanier, JR., John Matthew Kerwin, Gerald Michael Guay, N.
