Patent number: 11147918Abstract: A medicament delivery system configured to reduce the risk of inadvertently injecting medicament directly into a patient during a refill procedure via an external refilling apparatus. The medicament delivery system may include an implantable medical pump having a refillable medicament reservoir accessible via an access port, wherein the refillable medicament reservoir includes a flexible diaphragm having a nonlinear spring rate configured to create a relative vacuum within a medicament chamber when medicament is expelled from the medicament chamber beyond a predefined threshold, so as to spontaneously draw a quantity of medicament into the medicament chamber during the refill procedure to reestablish the predefined threshold, thereby confirming proper placement of a portion of the external refilling apparatus into the access port.Type: GrantFiled: October 23, 2018Date of Patent: October 19, 2021Assignee: Medtronic, Inc.Inventors: Steven Christenson, Touby Drew, James M.

Publication number: 20200121849Abstract: A medicament delivery system configured to serve as an aid in guiding a user through the procedural steps of refilling an implantable medical pump with an external refilling apparatus by tying the physical acts associated with a refill procedure to relevant information displayed on a user interface of an external programmer. The implantable medical pump may include a refillable medicament reservoir accessible via an access port having a needle detection sensor configured to detect the presence of a portion of an external refilling apparatus within the access port, and an external programmer configured to communicate with the implantable medical pump during the refill procedure, wherein sensed data gathered by the needle detection sensor is utilized by the external programmer to prompt the display of information relative to the procedural steps of the refill procedure.Type: ApplicationFiled: October 23, 2018Publication date: April 23, 2020Inventors: Steven Christenson, Touby Drew, James M.

Patent number: 9319852Abstract: A system and methodology to facilitate communication between non-compatible communication devices by utilization of a dynamic media proxy is provided. Information associated with an endpoint, such as, media capabilities, identity and system resource information is collected. Media proxy'ing is performed as part of capability negotiation. A dynamic media proxy is employed based on an analysis of the collected information. An analysis component can identify an endpoint that does not adhere to specific rules of transmission and can dynamically connect such an endpoint to a VTG (virtual talk group) via a proxy to prevent the endpoint from transmitting media into an active VTG that already has multiple talkers streaming media. Additionally, the location where media processing can occur can be dynamically determined based on the available system resources.Type: GrantFiled: October 24, 2014Date of Patent: April 19, 2016Assignee: Cisco Technology, Inc.Inventors: Shmuel Shaffer, Amit Barave, Steven Christenson, Marcelo Oliveira

Patent number: 8831664Abstract: A method is provided in one example embodiment and includes monitoring media streams associated with channels in a communication environment. The method also includes receiving an alert in one of the media streams and elevating a priority associated with the media stream receiving the alert. Elevating the priority can include increasing the volume of the media stream receiving the alert, changing a spatial direction for rendering the media stream receiving the alert, rendering the media stream receiving the alert to a priority spatial direction, identifying a primary channel and rendering the alert message to the primary channel, turning a volume down on media streams not receiving the alert, or a combination thereof.Type: GrantFiled: August 16, 2011Date of Patent: September 9, 2014Assignee: Cisco Technology, Inc.Inventors: Shmuel Shaffer, Steven Christenson

Publication number: 20110299404Abstract: A method is provided in one example embodiment and includes monitoring a plurality of channels provisioned for an endpoint. The method also includes reacting to an alert message by adjusting one of the channels for the endpoint. The adjustment is a selected one of increasing a volume associated with the channel receiving the alert message, or changing a spatial direction from which the alert message and an associated media stream are conveyed to the endpoint. In other embodiments, the adjustment provisions the alert message from a left ear to a right ear of an end user of the endpoint. In still other embodiments, the adjustment includes determining which is a primary channel of the channels and provisioning the alert message to the primary channel of the endpoint. The media stream associated with the alert message is also moved to a same spatial direction along with the alert message.Type: ApplicationFiled: August 16, 2011Publication date: December 8, 2011Inventors: Shmuel Shaffer, Steven Christenson

Publication number: 20100057860Abstract: Systems and methods of conveying feedback concerning transmissions sent using a one-to-many protocol are disclosed. Such feedback includes information indicating whether a message was received by anyone, by whom, whether the message was accessed, and whether a receiver of the message has acknowledged the message. A receiver is configured to provide such feedback, either in response to receiving a request to send feedback, or automatically. The feedback is sent via the same communications channel the message was sent on, or via a different communications channel. A message's sender is informed that feedback has been received for a given message, and a searchable log is kept of the feedback.Type: ApplicationFiled: August 29, 2008Publication date: March 4, 2010Inventors: Donna M.
