Publication number: 20240143365Abstract: Techniques are described for creating a container environment that implements direct communications between pods. This includes the creation of a management component (such as a control plane) of the container environment, the creation of nodes within an implementation component (such as a data plane) of the container environment, and the attaching of virtualized network interface cards (VNICs) to each node. This also includes creating a custom resource for each node, where the custom resource stores internet protocol (IP) addresses assigned to the node and stored within the VNICs for the node. Pods implemented within these nodes obtain an IP address from the VNICs for their respective node and communicate with each other utilizing the IP addresses via virtual communication devices and the VNICs.Type: ApplicationFiled: October 26, 2022Publication date: May 2, 2024Applicant: Oracle International CorporationInventors: Trung Hoai Nguyen, Joshua Aaron Horwitz

Patent number: 11963713Abstract: Retrieval of material from vessel lumens can be improved by electrically enhancing attachment of the material to the removal device. The removal device can have a core assembly that includes a hypotube coupled to a first electrical terminal and a pushwire coupled to a second electrical terminal, the pushwire extending through the hypotube lumen. An insulating layer separates the hypotube and the pushwire, and an interventional element is coupled to a distal end of the pushwire. The interventional element can be disposed adjacent to a thrombus. An electrical signal is delivered to the interventional element to promote adhesion of the thrombus to the interventional element. The electrical signal can optionally be a periodic waveform, and the total energy delivered can be between 0.75-24,000 mJ and the peak current delivered via the electrical signal can be between 0.5-5 mA.Type: GrantFiled: June 2, 2021Date of Patent: April 23, 2024Assignee: Covidien LPInventors: Gaurav Girdhar, Hoai Nguyen

Publication number: 20240126581Abstract: Techniques are described for implementing a container environment where each pod within the container environment is provided with a unique IP address and a virtual communication device such as an IPvlan device. Communications from source pods are directly routed to destination pods within the container environment by one or more virtualized network interface cards (VNICs) utilizing the unique IP addresses of the destination pods, without the need for bridging and encapsulation. This reduces a size of data being transmitted and also eliminates a compute cost necessary to perform encapsulation of data during transmission.Type: ApplicationFiled: October 12, 2022Publication date: April 18, 2024Applicant: Oracle International CorporationInventors: Trung Hoai Nguyen, Devon Howard Crouse, Sohan Patil

In some embodiments, a system for removing a thrombus includes an interventional element configured to be disposed proximate to or adjacent to a thrombus within a blood vessel. The system can include a signal generator in electrical communication with the interventional element. The signal generator can be configured to deliver an electrical signal to the interventional element. The electrical signal can include a waveform having a positive phase having a peak positive current and a first duration, and a negative phase having a peak negative current and a second duration. A magnitude of the peak positive current can be greater than a magnitude of the peak negative current, and the first duration can be greater than the second duration.Type: GrantFiled: August 30, 2021Date of Patent: April 2, 2024Assignee: COVIDIEN LPInventors: Gaurav Girdhar, Hoai Nguyen

Publication number: 20240086218Abstract: Techniques are described for transmitting metric data between tenancies. Metric data is gathered for resources within a customer tenancy of a multi-tenant environment. This metric data is sent to a service tenancy of the multi-tenant environment, where the service tenancy is separate from the customer tenancy. The metric data is validated and preprocessed within the service tenancy to make sure that all required fields (such as key-value pairs) are located within the metric data. The preprocessed metric data is then sent to a telemetry service for analysis.Type: ApplicationFiled: September 8, 2022Publication date: March 14, 2024Applicant: Oracle International CorporationInventors: Oscar Manuel Olazabal, Joshua Aaron Horwitz, Trung Hoai Nguyen
