Abstract: Systems and methods for performing hierarchical storage operations on electronic data in a computer network are provided. In one embodiment, the present invention may store electronic data from a network device to a network attached storage (NAS) device pursuant to certain storage criteria. The data stored on the NAS may be migrated to a secondary storage and a stub file having a pointer pointing to the secondary storage may be put at the location the data was previously stored on the NAS. The stub file may redirect the network device to the secondary storage if a read request for the data is received from the network device.

Abstract: The disclosure provides for a systems and methods for monitoring uterine contractions of a uterus of a mammal by reconstructing three-dimensional images of uterine surface electrical activity based on a noninvasively obtained body-uterus geometry and a plurality of body surface electrical potential maps.

Abstract: An angle of attack sensor includes a housing, a heated chassis positioned at least partially within the housing and defining a pocket, a mounting plate positioned adjacent the heated chassis and having a circular opening, an external surface facing away from the housing, and an internal surface facing toward the housing, and a vane assembly extending through the circular opening of the mounting plate. The vane assembly includes a vane extending from a root to a tip and a vane base connected to the root of the vane and positioned within the pocket of the heated chassis such that the vane base is offset inwardly from the external surface toward the housing.

Abstract: An angle of attack sensor includes a vane that is freely rotatable to align with a direction of an oncoming airflow over the vane. The airfoil includes a root proximate a vane hub that connects to a rotatable shaft, a tip opposite the root, a leading edge, a trailing edge opposite the leading edge, a first lateral face, a second lateral face, and a heating element disposed within the airfoil between the first and second lateral faces proximate the leading edge. The first lateral face extends from the leading edge to the trailing edge. The second lateral face is opposite the first lateral face and extends from the leading edge to the trailing edge. The first and second lateral faces are symmetric about a chord of the airfoil and each have an outer surface profile that is nonlinear and geometrically convex from the leading edge to the trailing edge.

Abstract: The bearings of aircraft angle of attack (AOA) vanes are susceptible to lightning strike damage, which causes fluting on the inner and outer races of the bearings and causes the bearings to generate friction, noise, and vibrations. To prevent the bearings from experiencing damage due to lightning strikes, the bearings, the shaft, and/or the mounting plate are configured to create an electric isolator to prevent the electric current from the lightning strike from passing through the bearings, thereby preventing the bearings from incurring lightning strike damage.

Abstract: An angle of attack sensor includes a housing having an open first end and a closed second end, a heated chassis positioned within the open first end of the housing, a mounting plate positioned on the heated chassis adjacent the open first end of the housing such that an internal chamber is formed between the heated chassis and the mounting plate, a transducer compartment between the heated chassis and the closed second end of the housing, and a water management system located adjacent the internal chamber and the transducer compartment. The water management system includes an annular chamber positioned in the internal chamber, a first tube at a first end of the annular chamber, and a second tube at a second end of the annular chamber. The first tube has a hole such that the first tube is in fluid communication with the annular chamber and the internal chamber, and the second tube is in fluid communication with the annular chamber and the transducer compartment.

Abstract: Systems and methods for managing electronic data are disclosed. Various data management operations can be performed based on a metabase formed from metadata. Such metadata can be identified from an index of data interactions generated by a journaling module, and obtained from their associated data objects stored in one or more storage devices. In various embodiments, such processing of the index and storing of the metadata can facilitate, for example, enhanced data management operations, enhanced data identification operations, enhanced storage operations, data classification for organizing and storing the metadata, cataloging of metadata for the stored metadata, and/or user interfaces for managing data. In various embodiments, the metabase can be configured in different ways. For example, the metabase can be stored separately from the data objects so as to allow obtaining of information about the data objects without accessing the data objects or a data structure used by a file system.
