Abstract: A method and system is provided for file and application management. The method may include configuring a destination system where the method further includes generating a filesystem image including an application file and files necessary for the destination system to execute the application file, generating a cryptographic signature of the filesystem image, transferring the filesystem image and the cryptographic signature to the destination system, cryptographically verifying the filesystem image with the cryptographic signature, and mounting the filesystem image on the destination system in a read-only manner.

Abstract: A latching device for overhead-type doors mounted for movement between a closed position and a raised position with respect to an opening defined by a frame. The latching mechanism includes a pivotable arm having a pivot end and an engagement end. The pivot end of the pivotable arm is mounted above the opening for pivotable movement about a substantially horizontal axis between a first position and a second raised position. The engagement end of the arm is adapted to engage a first latch portion associated with the door when the door is in a closed position and the arm is in the first position, and also adapted to engage a second latch portion associated with the door when the door is in the raised position and the arm is in an intermediate position between the first and second positions.
