Patent number: 11950713Abstract: Systems disclosed herein are directed to a display stand unit for a retail environment. The display stand unit includes a base having an interior and a display stand. The display stand includes a stem that connects to and extends upwardly from the base and a receiving surface that is suspended above and spaced away from the base by the stem. The receiving surface is configured to releasably hold an electronic device above and spaced away from the base. The display stand unit further includes a security cable that extends out from the base. The security cable is configured to attach to the electronic device to movably secure the electronic device to the base. The display stand unit further includes a retractor disposed within the interior of the base and connected to the security cable. The retractor automatically retracts the security cable.Type: GrantFiled: February 4, 2022Date of Patent: April 9, 2024Assignee: Apple Inc.Inventors: David Samuel Kumka, Clayton R. Woosley, Daniel S. Foster, Eric Weijia Wang, Gregory R. Ritter, Joshua Adams, Christopher Hu, Priya K. Nambiar

Patent number: 9126052Abstract: Approaches for rate initialization and overdrive pacing used during capture threshold testing are described. Cardiac cycles are detected and the cardiac events of a cardiac chamber that occur during the cardiac cycles are monitored. The number of intrinsic beats in the cardiac events is counted. Initialization for a capture threshold test involves maintaining a pre-test pacing rate for the capture threshold test if the number of intrinsic beats in the cardiac events is less than a threshold. The pacing rate is increased for the capture threshold test if the number of intrinsic beats in the cardiac events is greater than the threshold.Type: GrantFiled: March 24, 2014Date of Patent: September 8, 2015Assignee: Cardiac Pacemakers, Inc.Inventors: Eric K. Enrooth, Sunipa Saha, Clayton S. Foster, Yanting Dong

Patent number: 9008772Abstract: An apparatus comprises a control circuit that initiates a normal pacing mode for delivery of electrostimulation energy to the heart chamber. In response to an indication to initiate a threshold test, the control circuit determines an electrode configuration used to deliver the electrostimulation energy in the normal pacing mode, selects a first threshold test mode when a sensing electrode independent from the set of pacing electrodes is unavailable for the heart chamber, wherein a cardiac activity signal is sensed using a set of sensing electrodes that includes an electrode common to the set of pacing electrodes, and selects a second threshold test mode when a sensing electrode independent from the set of pacing electrodes is available for the heart chamber, wherein the cardiac activity signal is sensed using a set of sensing electrodes that excludes an electrode common to the set of pacing electrodes.Type: GrantFiled: November 26, 2012Date of Patent: April 14, 2015Assignee: Cardiac Pacemakers, Inc.Inventors: Aaron R. McCabe, Deepa Mahajan, David W. Yost, Clayton S. Foster, Shibaji Shome, Amy Jean Brisben

Patent number: 8688216Abstract: Cardiac electrostimulation energy is delivered to a heart chamber of a subject according to a normal pacing mode using a set of implantable pacing electrodes. When a threshold test for the heart chamber is initiated and a sensing electrode independent from the set of pacing electrodes is unavailable for the heart chamber, cardiac electrostimulation energy is delivered to the subject according to a threshold test mode. The threshold test mode includes sensing a cardiac activity signal from a subject using a set of sensing electrodes that includes an electrode common to the set of pacing electrodes, and changing the electrostimulation energy and sensing a resulting cardiac activity signal using the set of sensing electrodes to determine the optimum electrostimulation energy for capture of the heart chamber.Type: GrantFiled: November 26, 2012Date of Patent: April 1, 2014Assignee: Cardiac Pacemakers, Inc.Inventors: David W.

Patent number: 8521285Abstract: Methods and devices are described that allow estimation of an electrostimulation capture threshold, such as a dedicated bipolar pacing vector threshold. In an example, an equal-energy assumption between first and second pacing vectors can be used to estimate an electrostimulation capture threshold of a second pacing vector from a measured electrostimulation capture threshold of the first pacing vector and impedances of the first and second pacing vectors. In an example, a relationship between first and second pacing vectors can be determined from measured data, and a parameter of the relationship can be used with a measurement of an electrostimulation capture threshold of the first pacing vector to estimate an electrostimulation capture threshold of the second pacing vector.Type: GrantFiled: October 18, 2010Date of Patent: August 27, 2013Assignee: Cardiac Pacemakers, Inc.Inventors: Amy Jean Brisben, Aaron R.
