Abstract: A method of managing access to a key. The method comprises associating the key with an encrypted data object, the key being required to decrypt the data object; generating a number of fragments of the key, the number of fragments corresponding to a number of parties subject to a fragmentation agreement; and encrypting each fragment with a public key corresponding to each of the parties. The method further comprises encrypting each encrypted fragment with a public key of a trusted party; and storing the encrypted fragments with the encrypted data object on a server of the trusted party.

Abstract: A framework for sharing protected content includes a safe service comprising an access service and a content service; and a safe access service application integrated with at least one social media service application, said safe access service application constructed and adapted to provide controlled access to protected content stored in the content service, said controlled access being via a user interface (UI) of the at least one social media service application.

Abstract: A method for mapping a fracture network that includes determining a source of at least one seismic event from features in recorded seismic signals exceeding a selected amplitude (“visible seismic event”). The signals are generated by a plurality of seismic receivers disposed proximate a volume of subsurface to be evaluated. The signals are electrical or optical and represent seismic amplitude. A source mechanism of the at least one visible seismic event is determined. A fracture size and orientation are determined from the source mechanism. Seismic events are determined from the signals from features less than the selected amplitude (“invisible seismic events”) using a stacking procedure. A source mechanism for the invisible seismic events is determined by matched filtering. At least one fracture is defined from the invisible seismic events. A fracture network model is generated by combining the fracture determined from the visible seismic event with the fracture determined from the invisible seismic events.

Abstract: There is disclosed a pinch sealer drive mechanism for a form fill and seal machine, or the like, wherein a bi-directional rotary actuator is employed to rotate a crank with two oppositely disposed levers, each of which is linked to a slide. Thus, there are two substantially identical symmetrically disposed linkages consisting of a lever, a link and a slide, whereby the slide is caused to have a relatively low velocity at the extremes of its motion, thereby producing a smooth vibration free operating mechanism to which the heat seal bars or other pinch sealing apparatus may be attached. A preferred embodiment of the apparatus has a duplicate of the above described crank, lever, and link mechanism for the distant end of the slide, and the second mechanism is driven from and synchronized with the first by an endless belt drive to one of two sprockets fixed on a rotatable shaft and then from the second sprocket on such shaft to a sprocket connected to rotate the crank of the second mechanism.

Abstract: There is disclosed a food tray film wrapping machine having an improved film feeding mechanism particularly adapted to feeding pre-printed film from a continuous roll and assuring proper registration of the printing on the film-wrapped tray, including a receiving position for a large film roll provided with a pair of rollers for cradling the film roll, a film feed motor separate from the main wrapping machine motor, an automatic motor control responsive to optical sensors for sensing an index mark on the film sheet and for sensing the presence of a food tray at the machine wrapping station to stop and start the film feed motor, a perforating knife positioned adjacent the index mark sensor for perforating the film on a line across the film without separating it, and an arrangement of a filmfolding arm with gripping means for the film whereby the film sheet is separated at the perforation line as the folding arm tucks the trailing edge of the film sheet at the wrapping station under the food tray.

Abstract: There is disclosed an improved form of ejection and transport mechanism in a tray wrapping machine with an elevator that elevates a tray of meat or other product causing it to be wrapped on top and sides by a sheet of stretchable PVC film from a storage roll after which arms fold the edges of the film underneath the tray; the mechanism includes a pusher bar which pushes the fully wrapped tray off of the side of the tray elevating platform while the tray is constrained by a freely rotating endless hold-down belt serving to restrain and guide the tray; the tray is received from the pusher bar action onto a powered roller conveyor with rolls arranged radially along an arc of 90.degree.; the motion of the finished tray upon exiting the roller conveyor is substantially parallel to the longitudinal axis of the tray wrapping machine defined by the direction of travel of the PVC film from the storage roll to the elevator position.
