Abstract: Embodiments of the invention relate to systems, methods, and computer program products for automated data purge in an e-discovery system. The automated data purge process determines files within an e-discovery file system that qualify for purging based on one or more purge policies, locates the files within the file system and automatically purges the data from the file system. Additional embodiments provide for automatically creating log entries that track the details of the purge and automatically generating and communicating alerts/messages that notify concerned parties of the data purge. As such the present invention is able to accurately and automatically purge data from an electronic discovery file system and provide for detailed purge data tracking, as well as, purge notification.

Abstract: A developer cartridge for containing a developer and for delivering the developer to a developer hopper of an electro-photographic machine. A developer containment portion includes a first portion having an at least partially closed volume configured to contain the developer and a second portion adjacent the first portion and having an opening configured to deliver the developer to the developer hopper. A sealing gasket is disposed adjacent the second portion of the developer containment portion and surrounds at least a portion of a circumference of the opening. A first cover is disposed adjacent the second portion of the developer containment portion and is positionable between an open position for delivery of the developer and a closed position for preventing delivery of the developer. The sealing gasket contacts the first cover to prevent undesired leakage of the developer therebetween.

Abstract: A slide bolt type of closure locking system is disclosed in various configurations in various orientations. A lever arm is used to operate the bolt slide. A detent arrangement normally keeps the lever arm in a nested rest position. The arm can be released from the detent to pivot the arm outward to operate the bolt slide. A pivot blocker is operable to prevent folding of the arm from its outward posture when needed to operate the bolt slide. Various lock case configurations are adapted to embedded or socket-mounting, or channel mounting, or surface mounting installations in swinging, sliding or folding closures.

Abstract: A crutch has a hands-free attachment. The crutch has a pair of generally spaced apart vertical members having an upper end and a brace connected to the upper end of the each of the pair of vertical members which provides upper end structural support and an interface with the underarm of a user. The crutch also has a handgrip connected to and positioned between the vertical members which provides for an interface with a hand of the user. The crutch further includes a peg mounted to the vertical members between the handgrip and the brace and extending laterally therefrom, for engagement by a forearm of the user.

Abstract: An improved self-aligning tree delimbing apparatus for use in conjunction with a knuckle boom loader having an inner frame member pivotally mounted and concentrically received within an outer frame member, which is rigidly attached to a base member. Pivotally mounted within the inner frame member is a tree delimbing cutter head assembly having opposing pairs of tree guide arms and tree delimbing arms pivotally mounted thereon, thereby allowing for simultaneous multi-dimensional pivotal motion of the cutter head assembly within the frame members. Such motion allows the cutter head assembly to easily align with the longitudinal axis of the trees being delimbed, thereby increasing the efficiency of the apparatus while reducing the binding stresses and necessary force applied by the knuckle boom loader.
