Abstract: A method and apparatus for providing a loudspeaker assembly is provided. In accordance with at least one embodiment, a method is provided which comprises forming a loudspeaker frame so as to define a driver housing portion, a horn portion, and a conformal portion. A driver aperture is defined for the driver housing portion, and a port aperture is defined for the horn portion. A driver is attached to the loudspeaker frame proximate to the driver aperture. A rear baffle is applied to a first conformal portion surface of the conformal portion of the loudspeaker frame. The rear baffle defines a horn cavity wall of a horn cavity of the horn portion. The horn cavity has an increasing cross sectional area as the distance from the driver housing portion increases. A grille is applied to a second conformal portion surface of the conformal portion of the loudspeaker frame.

Abstract: A method and apparatus for handling data during link suspend pulse and the silent line state of a network device operating in a low power link suspend mode is presented. Accordingly, a new generation of network devices capable of operating in both the full power operational mode of prior art network devices, and a low power “link-suspend” operational mode are presented. The low power “link-suspend” (LS) mode reduces the power consumption of a LAN communications link at the physical layer by eliminating the need to continuously transmit standard idles to maintain link between two linked partners. In the LS mode, a low duty cycle “link-suspend-packet” (LSP) is transmitted between periods of silent line state (SLS). During the SLS, which is a non-data transmission period, the transmitter may be turned off to conserve power therefore preventing the receiver from immediately knowing the phase of an incoming data.
