Abstract: A brush seal includes a bristle pack disposed between a top plate and a back plate. A sliding backing plate is disposed between the bristle pack and the back plate. The bristle pack includes a first bristle set that extends across a seal gap between a first engine component and a second engine component to prevent leakage across the seal gap and a second bristle set that exerts a force on the sliding backing plate. The sliding backing plate supports at least a portion of the first bristles and extends across the seal cavity to contact the second component. The force exerted on the sliding backing plate drives the sliding backing plate into contact with the second component.

Abstract: An automated tool control system provides both inventory control of items stored in the system and monitoring of the charging status of rechargeable inventory items such as tools and batteries stored in the system. For these purposes, the tool control system includes storage locations for storing tools and other inventory items, and the storage locations include at least one storage location located in a charger operative to charge a rechargeable tool, battery, or battery pack disposed therein. In operation, the tool control system may monitor the charging status of any tool, battery, or battery pack disposed in the storage location of the charger through monitoring of battery status indicators of the tool, battery, battery pack, or charger; through monitoring of current or voltage drawn by the tool, battery, battery pack, or charger; or through wired or wireless communication with a communication enabled tool, battery, battery pack, or charger.

Abstract: A seal assembly extends along an axis and seals an axial (and/or radial) gap between a first component and a second component. The seal assembly includes a seal carrier and a seal element. The seal element extends axially (and/or radially) between a first portion and a second portion. The first portion of the seal element is slidingly arranged within a slot in an axial end (or a radial side) of the seal carrier. The second portion of the seal element is configured to axially (and/or radially) engage the second component.

Abstract: An automated asset management system includes a plurality of storage locations for storing objects, and first and second sensing subsystems each configured to sense presence or absence of the objects in the plurality of storage locations. The first and second sensing subsystems are used to sense the presence or absence of a same particular object using different respective sensing modalities. In operation, a first scan of the storage locations is performed using the first sensing subsystem, and the presence or absence of the particular object is determined using the first sensing modality. In turn, a second scan of the storage locations is performed using the second sensing subsystem, and the presence or absence of the particular object is confirmed using both the result of the determination made using the first sensing modality and a determination of the presence or absence of the particular object using the second sensing modality.

Abstract: An assembly for a turbine engine includes a turbine engine first component, a turbine engine second component and a seal assembly. The first component includes a groove and a groove surface. The second component includes a tongue that extends into the groove to a tongue surface. The seal assembly at least partially seals a gap between the groove surface and the tongue surface. The seal assembly includes a rope seal and a clip that attaches the rope seal to the tongue. The rope seal is arranged within the groove between the groove surface and the tongue surface.

Abstract: Systems and methods of detecting copying of code or portions of code involve disassembling a set of compiled code into an architecture-agnostic intermediate representation. The intermediate representation is used to form a number of cryptographically hashed overlapping shingles. The number of cryptographically hashed overlapping shingles can be searched against a database of cryptographically hashed overlapping shingles to identify copied code.

Abstract: A calibration monitoring system is provided to automatically monitor the calibration status of tools and other inventory items, such as upon the items being issued from or returned to the automated calibration monitoring system. The system identifies an inventory item, for example a calibrated torque wrench or other calibrated tool identified based on a unique identifying tag attached thereto. The system retrieves a calibration parameter value for the item from a calibration database, and completes a calibration measurement of the item based on the calibration parameter value. In the example, a torque measurement of the calibrated torque wrench can thus be automatically completed. In turn, the system determines a current calibration status of the item based on the calibration measurement, and selectively enables or disables issuance of the inventory item from the system according to the item's status as being in calibration or out of calibration.

Abstract: Methods and apparatus are described. A method includes an accelerated processing device running a process. When a maximum time interval during which the process is permitted to run expires before the process completes, the accelerated processing device receives an operating-system-initiated instruction to stop running the process. The accelerated processing device stops the process from running in response to the received operating-system-initiated instruction.

Abstract: An inventory control system is described that includes a tool storage device including a drawer or a tray providing a pallet, wherein the pallet includes storage locations for objects; a sensing device configured to form an image of the storage locations; and a data processor configured to determine presence or absence of the pallet and presence or absence of objects within the storage locations of the pallet using the information from the image.
