Patent number: 8812127Abstract: A system comprises an implantable medical device (IMD), a external user interface device, and a radio frequency link quality assessment (LQA) device. The external user interface device and the IMD are adapted to potentially use one or more of a plurality of available wireless communication channels to communicate. The LQA device is positioned to receive a radio frequency communication between the IMD and the external user interface device. At least one of the IMD, the external user interface device, and the LQA device is adapted to evaluate signal and noise strength of the available channels to determine respective signal and noise levels for each channel by using the noise level for the target channel and interference potential for corresponding adjacent channels to the target channel as inputs to a function to provide a value for a LQA for the target channel, and select a preferred communication channel based on the LQA value for each of the available wireless communication channels.Type: GrantFiled: March 10, 2010Date of Patent: August 19, 2014Assignee: Cardiac Pacemakers, Inc.Inventor: Scott Freeberg

Patent number: 8423142Abstract: A first chamber minute ventilation rate is determined based on a first transthoracic impedance signal received from a first chamber of a heart and a second chamber minute ventilation rate is determined based on a second transthoracic impedance signal received from a second chamber of the heart. A processor compares the minute ventilation rates to determine a rate. In one embodiment, an accelerometer sensor provides data for evaluating propriety of a rate. Before implementing a rate change, signals from multiple sensors are cross-checked.Type: GrantFiled: October 31, 2011Date of Patent: April 16, 2013Assignee: Cardiac Pacemakers, Inc.Inventor: Scott Freeberg
