Abstract: A transport system for delivery or retrieval of a biostimulator, such as a leadless cardiac pacemaker, is described. The biostimulator transport system includes a docking cap supported by a bearing within a bearing housing. The bearing allows relative rotation between a torque shaft connected to the docking cap and an outer catheter connected to the bearing housing. The bearing housing and the docking cap include respective bearing retainers that constrain the bearing within the bearing housing without a weld attachment. The weldless retainers of the biostimulator transport system provide a robust mechanical securement of the bearing that is not vulnerable to corrosion. Other embodiments are also described and claimed.

Abstract: A request to store a container image is received from a device associated with a customer of a computing resource service provider. Validity of a security token associated with the request is authenticated using a cryptographic key maintained as a secret by the computing resource service provider. One or more layers of the container image is built based at least in part on at least one build artifact to form a set of built layers. The software image including the set of built layers is stored in a repository associated with the customer. A manifest of metadata for the set of built layers is stored in a database of a structured data store. The container image is obtained in the form of an obtained container image. The obtained container image is deployed as the software container in at least one virtual machine instance associated with the customer.

Abstract: A request to update a software container image within a container registry hosted by a computing resource service provider is received from an entity associated with a customer account with the computing resource service provider, where the container registry is a scalable distributed data storage service. The software container image is stored in the container registry in association with the customer account. A layer of the software container image stored in the container registry is scanned for a reference identifier associated with a security vulnerability as a result of said scan finding the reference identifier within the software container image, notice is provided to the entity indicating that the security vulnerability was found. Software within the software container image is updated based at least in part on the vulnerability scan; and the update software is deployed.

Abstract: Technology for rewarding affiliates is provided. In one example, a method may include determining a physical location of a computing device. A purchase intent from the computing device while at the physical location may be identified. An affiliate associated with the physical location may be rewarded for the purchase intent.

Abstract: A leadless biostimulator including an attachment feature to facilitate precise manipulation during delivery or retrieval is described. The attachment feature can be monolithically formed from a rigid material, and includes a base, a button, and a stem interconnecting the base to the button. The stem is a single post having a transverse profile extending around a central axis. The transverse profile can be annular and can surround the central axis. The leadless biostimulator includes a battery assembly having a cell can that includes an end boss. A tether recess in the end boss is axially aligned with a face port in the button to receive tethers of a delivery or retrieval system through an inner lumen of the stem. The attachment feature can be mounted on and welded to the cell can at a thickened transition region around the end boss. Other embodiments are also described and claimed.

Abstract: A system, method, apparatus, and computer program product for a privacy ensured brokered identity federation system. The privacy ensured brokered identity federation system connects a user in a brokered identity federation environment that blinds relying parties (RP) from credential service providers (CSP), blinds CSPs from RPs, and blinds a user's identity and data from the federation middleware hubs. The system utilizes ring signatures to attest to CSPs that a valid RP of the federation is making a request. The process utilizes CSP ring signatures to assure RPs that a valid CSP of the federation has provided a response. The process utilizes per transaction encryption keys created by the RP to ensure the federation has no access to data messages. It can further ensure that only the correct RP can decrypt a CSP response.

Abstract: A biostimulator transport system, such as a biostimulator retrieval system, having a torque limiter to allow a torque shaft to slip rotationally relative to a handle, is described. The torque limiter can connect the torque shaft to the handle, and can include a slip mechanism, such as a flat spring or apposed clutch faces, that allow the torque shaft to slip relative to the handle when a resistance torque at a distal end of the torque shaft exceeds a torque threshold. Accordingly, torque can be applied to a biostimulator by the torque shaft with a reduced likelihood of over-torqueing the biostimulator within the target tissue. Other embodiments are also described and claimed.

Abstract: Catheter-based delivery systems for delivery and retrieval of a leadless pacemaker include features to facilitate improved manipulation of the catheter and improved capture and docking functionality of leadless pacemakers. Such functionality includes mechanisms directed to deflecting and locking a deflectable catheter, maintaining tension on a retrieval feature, protection from anti-rotation, and improved docking cap and drive gear assemblies.

Abstract: An electronic bidding service is described which substantially automatically acquires items for buyers in response to bidding information entered by the buyers. To function in this manner, the electronic bidding service makes use of an item authority. The item authority links items specified in different offers to master reference information associated with the items, thereby allowing the electronic bidding service to identify groups of offers which are selling the same or related item. In one case, a buyer can instruct the electronic bidding service to obtain a desired item from a specific offer. If this bid is unsuccessful, the electronic bidding service can extend the bidding procedure to one or more other offers that feature the same or related item. This extension is based on the master reference information.
