International Classification:

F16J 1508

US Classification:

277409, 277500, 277602, 277603, 415134

Abstract:

A low leakage sealing system is provided between a steam pipe and a housing comprised of a pair of shells and a nozzle box movable relative to one another. The sealing system includes large and small diameter sealing rings engaging the pipe and shells or nozzle box and a secondary sealing element disposed between the sealing rings and one of the pipe and shells or nozzle box. The sealing elements comprise frustoconical elements having curved end surfaces forming primary seals with the sealing rings and the housing. In another form, the sealing system includes annular carrier elements having radially opening cavities for receiving sealing rings engageable with the pipe and housing, respectively. The carrier elements are axially spaced from a plurality of sealing rings to provide the low leakage sealing system.

International Classification:

H04S 7/00

Abstract:

An audio engine is provided for acoustically rendering a three-dimensional virtual environment. The audio engine uses geometric volumes to represent sound sources and any sound occluders. A volumetric response is generated based on sound projected from a volumetric sound source to a listener, taking into consideration any volumetric occluders in-between. The audio engine also provides for modification of a level of detail of sound over time based on distance between a listener and a sound source. Other aspects are also described and claimed.

Abstract:

A method of updating an authentication credential may include, by a client device, receiving an authentication credential from a user, generating an access key using the authentication credential, determining whether the access key decrypts a storage key that encrypts at least a portion of a computer-readable storage medium of the client device, and in response to determining that access key does not decrypt the storage key, sending a request to an authentication server. The request may include the authentication credential. The method may include receiving, from the authentication server, a recovery key, and generating an updated storage key using the decryption key.
