Abstract: A head mounted device includes a housing, lenses connected to the housing, and a lens cover that is connected to the housing and is movable between a connected position and a disconnected position with respect to the housing.

Abstract: An abrasive article comprising: a body comprising abrasive grains contained within a bond material comprising a metal or metal alloy, wherein the body comprises a ratio, (VAG/VBM), of volume of abrasives (VAG) to volume of bond (VBM), of between about 0.127 and about 1.27, wherein (VAG) is a volume percent of abrasive grains within the total volume of the body, (VBM) is the volume percent of bond within the total volume of the body, wherein the body could have about 15% to about 55% porosity, more preferably about 20% to about 55% and most preferably 25% to 55% porosity, wherein the bond material comprises at least 1% of an active bond composition of the total volume of the bond, a portion of which is at the interface of the abrasive grains and the bond material.

Abstract: Methods, systems, and computer-readable media for monitoring states of application packages deployed on a cloud-based application deployment platform. A notification service retrieves a copy of a deployed application package from the cloud-based deployment platform, and determines libraries of the application package. The notification service can then determine security vulnerabilities in the libraries, and provide notifications on the vulnerabilities of the application package to a user or developer.

Abstract: Methods, systems, and computer-readable media for monitoring states of application packages deployed on a cloud-based application deployment platform. A notification service retrieves a copy of a deployed application package and metadata associated with the application package from the cloud-based deployment platform, and identifies libraries of the application package. The notification service can then determine which, if any, libraries are or will become out-of-date, and obtain license information about the libraries. The notification service can provide notifications of any outdated components and on license compatibilities or incompatibilities. The notification service can automatically restage the application package, or update the license, upon finding outdated components or license incompatibilities.
