Abstract: A grille for ventilation apparatus arranged downstream of insufflation elements of a ventilation apparatus, the grille including a grid portion arranged upstream of a stator portion. The insufflation elements may include a fan. The grid portion may include fins which form concentric rings.

Abstract: Various systems and methods for capability access management are disclosed herein. In one example, a system includes a memory and a processor to send a signed custom capability description (SCCD) received from a first vendor to the memory for storage. The system may send an application received from a second vendor to the memory for storage. The system attempts to match the application to an authorization listing of the SCCD, where the application can be modified to allow access to a previously inaccessible custom capability in response to the application matching the authorization listing of the SCCD.

Abstract: Active power factor correction can be used to reduce input harmonics in an aircraft power distribution system. In an embodiment, one or more power factor correction (PFC) units can be placed in a power distribution system to profile an input signal. Each PFC unit can include a converter, such as an AC-DC converter, and can be placed in the power system bus on the input side of the load. In an embodiment, a PFC unit can include a boost rectifier topology with active power factor correction for harmonics elimination.

Abstract: A resource abstraction layer for use in a media processing environment includes a configuration file and a set of computer-executable instructions. Both network-based and locally-accessible resources are indirectly accessible via the resource abstraction layer. The configuration file has at least two data structures—a first data structure storing “virtual resource identifiers,” which reference particular resource usable in connection with rendering a particular media presentation, and a second data structure storing “virtual location identifiers,” which reference one or more locations at which particular resources are stored. The set of computer-executable instructions facilitates use of the configuration file, and seamless indirect access by the media processing environment to particular resources, regardless of where such resources are located. Temporary resources may be rendered while a particular resource is being accessed via the resource abstraction layer.
