Abstract: A magnetic anti-lock device for a rotating shaft is described. The magnetic anti-lock device utilizes opposing magnets to reduce the varying force required to rotate the shaft and increases efficiency of the rotating shaft. The magnetic anti-lock device includes at least one inner magnet attached to the rotating shaft, and at least one outer magnet fixed in position relative to the rotating shaft. The inner magnet passes the outer magnet each time the shaft rotates creating a repulsive force to reduce the force necessary to rotate the shaft.

Abstract: Printed textiles and related manufacturing methods are provided. Textile materials can include laced mesh fabrics made of rigid components. The laced mesh structures are designed for space applications, including but not limited to adaptive and foldable reflectors, capturing systems, debris and micrometeorite shielding, shading systems, sample capturing, and various other applications.

Abstract: Embodiments relate to systems and methods for tracking local and remote file usage, and aggregating the resulting file usage statistics for presentation to a user. The operating system of a local computer can track and generate local file usage statistics, such as most recently used files and editing time. A Web application or service, such as an email or word processing application or service, can record the file usage data for a user's remote stored or served files. A file usage aggregator module, which can be located or resident in the operating system of the local computer or hosted at a Web site, can receive and combine the local and remote file usage statistics. The file usage aggregator module can generate a display of the aggregated file usage statistics, so that local and remote files are listed in a most-recently used order, on a combined basis.

Abstract: A nozzle system including a nozzle body configured to dispense fluid therethrough and a lever coupled to the nozzle body and movable in a lever plane between a non-operating position and an operating position. The nozzle system further includes a latch assembly having an engagement surface and a cam. The cam is coupled to or positioned on one of the nozzle body or the lever, and the engagement surface is coupled to or positioned on the other one of the nozzle body or the lever. The nozzle system is configured such that when the lever is moved from the non-operating position to the operating position, the engagement surface engages the cam to cause at least one of the engagement surface or the cam to move relative to the other such that the lever is automatically retainable in the operating position by the latch assembly.

Abstract: In accordance with embodiments of the present disclosure, systems and methods for safely, and cost-effectively activating a mechanical perforator using a pyrotechnic initiated hydrostatic activating mechanism. The mechanism includes a piston connected to a power rod. The piston is activated by the rupturing of a disc, which separates a first chamber from a second chamber containing the piston. Upon rupturing of the disc, wellbore fluids fill the second chamber forcing the piston to move from a first position to a second position, which causes activation of the mechanical perforator. The first chamber may optionally be filled with a pressurized gas, such as nitrogen or air, to add a boost assist to activation of the piston.
