US Classification:

370256, 709252

Abstract:

Embodiments of the invention provide a method for building a classification tree based on a plurality of rules. Each rule includes multiple fields having different priority levels. The classification tree is built to provide for single pass classification of a received packet according to the multiple rules. The classification tree is built level-by-level, where each level represents one of the priority levels. Building a single level of the classification tree includes: creating, for each of the logical decision paths received from a next higher priority level, a respective sub-tree. The sub-tree includes only nodes and related logical decision paths that are necessary to satisfy rules associated with a respective next higher priority level node. Building of the single level further includes: creating, for each non-lowest priority level, logical decision paths from nodes within the current priority level to a next lower priority level.

Abstract:

A headphone is provided with a housing and a transducer. The housing has a baffle surface with a recess formed therein and an edge formed about a periphery of the baffle surface. The transducer disposed in the recess and supported by the housing. The headphone is also provided with an ear cushion and a sheet. The ear cushion has a base formed in an annular shape and connected to the housing about the edge and a contact surface spaced apart from the base to engage a portion of a user's head around an outer ear, wherein the ear cushion defines a cavity to collectively form an acoustic chamber with the user's head. The sheet is disposed over the baffle surface with a hole formed therethrough and aligned with the transducer. The sheet is also formed of a sound absorbent material to suppress sound reflections within the acoustic chamber.
