  • Publication number: 20230409307
    Abstract: The present system automatically allows a user to create a pipeline for performing a progressive rollout and automatically performs the rollout in progressive steps. As part of creating a pipeline, a user creates multiple rollout phases and multiple approval phases. At each rollout phase, a portion of users using the current version of a software receive a rollout or update. The types of users may be configured based on user attributes. The approval phase for each rollout may determine if the software at the customer location is satisfying certain key performance indicator (KPI) requirements and whether the software update is correcting what it was intended to address. The present technology may automatically apply the updates, automatically review the performance of the updated application, and automatically approve the rollout to move onto the next phase, all without any administrator decisions.

  • Publication number: 20210283633
    Abstract: An apparatus and a method are provided for a sprayer nozzle support to a pump mechanism of a trigger sprayer assembly. The sprayer nozzle support generally comprises a tower portion and a first and second side protrusions. The tower portion is configured to convey stability to the pump mechanism when a screw cap of the trigger sprayer assembly is screwed onto a neck of a container. A top of the tower portion is configured to support the pump mechanism and a bottom of the tower portion is configured to contact the screw cap. The first and second side protrusions provide structures whereby the sprayer nozzle support may be removed from the trigger sprayer assembly. A curved proximal surface of the tower portion and the first and second side protrusions facilitates an unobstructed grasping of the trigger sprayer assembly in a hand.
