Patent number: 11925403Abstract: A cryoablation catheter, including a first capsule body, a core tube and a heat insulation part, wherein the first capsule body is mounted at a front end of the core tube, and has a front end area adapted for fitting to myocardial tissue during a cryoablation process and a rear end area exposed to blood; the core tube has a first looping path provided therein which is adapted for a first fluid with low temperature to be filled into or flow out of the first capsule body; the heat insulation part is at least partially fitting to the rear end area, and is adapted for reducing heat exchange efficiency between the first fluid and the blood in an atrium. The cryoablation operating apparatus and the cryoablation equipment thereof can effectively reduce the heat exchange between the cryoablation catheter and the blood during a cryoablation process.Type: GrantFiled: April 12, 2019Date of Patent: March 12, 2024Assignee: Piedmont Medsystems (Zhuhai) Co., Ltd.Inventors: Jiahua Xiao, Alan De La Rama, Cary Kunihiko Hata

Publication number: 20210397313Abstract: A device implementing a system to render widget user interfaces for display of dynamic application content on a home screen includes a processor configured to identify a container associated with a first home screen, the container corresponding to an application. The processor is further configured to retrieve data describing a plurality of user interfaces, associated with respective times, of the application. The processor is further configured to render, based on the data, the plurality of the user interfaces in advance of the respective times. The processor is further configured to determine that the first home screen is currently displayed. The processor is further configured to select a first rendered user interface from the rendered user interfaces, wherein the respective time associated with the first rendered user interface corresponds to a current time. The processor is further configured to display the selected first rendered user interface on the first home screen.Type: ApplicationFiled: June 17, 2021Publication date: December 23, 2021Inventors: Neil N. DESAI, Nahir A. KHAN, Andrew Brett CATO, John LOUCH, Patrick Reid METCALFE, Antony J. DZERYN, David A. SCHAEFGEN, Jacob FRAIMOW, Nils Moshe Abraham HAYAT, Jacob Alan XIAO

Publication number: 20190268263Abstract: Techniques whereby a LAN-side border router observes all packets of an application flow from both directions so that the application recognition performed on the LAN-side border router functions properly. A border router may implement flags in a flow cache to indicate whether the border router is the LAN-side border router and/or a WAN-side border router for an application flow. As packets are received at a border router at either the LAN interface or WAN interface, the flags associated with packet's application flows are examined to determine if the border router is the LAN-side border router for the application flow. If so, then application recognition and routing control may be performed. If not, the packet may be redirected to another border router that may be the LAN-side border router or the WAN-side border router for the application flow to insure that border router observes the packet.Type: ApplicationFiled: March 4, 2019Publication date: August 29, 2019Inventors: Alan Xiao-rong Wang, Dapeng Liu, Yu Zhang, Gaofeng Tao

Patent number: 10389615Abstract: In one embodiment, enhanced packet flow monitoring is performed by packet switching devices in a network. A packet switching device is configured to monitor a flow of packets passing through the packet switching device, including detecting a gap in consecutive packets of the flow of packets, and attributing the gap as not being dropped one or more packets based on a particular time duration between a last received packet of the flow of packets before said detected gap and a first received packet of the flow of packets after said detected gap. In one embodiment, the gap is attributed to not being dropped packets when the particular time duration is greater than a threshold value; and conversely, attributed to being dropped packets when the particular time duration is less than a same or different threshold value.Type: GrantFiled: June 29, 2015Date of Patent: August 20, 2019Assignee: Cisco Technology, Inc.Inventors: Tony Changhong Shen, Yu Zhang, Alan Xiao-Rong Wang, Aviv Prital, Doron Oz, Kathy Xia Ke

Patent number: 9699065Abstract: A software defined network controller detects when a host has moved between network elements in a network. The controller generates a list of network elements to which the host has roamed, the list being sorted by time when the host is attached to a network element so that a most recent network element to which the host is attached is the root network element and at a head of the list. The controller updates the root network element in the list first for traffic flow associated with the host. The controller sends commands to the network elements to program a tunnel from each previous point of attachment network element in the list to the most recent root network element in the list in reverse order of the roaming path so as to route traffic for the host via a tunnel.Type: GrantFiled: August 7, 2015Date of Patent: July 4, 2017Assignee: Cisco Technology, Inc.Inventors: Gaofeng Tao, Alan Xiao-rong Wang, Yu Zhang, Dapeng Liu
