Abstract:

A system and method for processing signal in a remote facility includes an IP network and a first local collection facility that includes a first plurality of receiving circuit modules receiving a first plurality of channel signals and generating a first plurality of IP encoded signals from the first plurality of channel signals and a first router routing the first plurality of encoded signals to the IP network. The system also includes a second local collection facility comprising a second plurality of receiving circuit modules receiving a second plurality of channel signals and generating a second plurality of IP encoded signals from the second plurality of channel signals and a second router routing the second plurality of encoded signals to the IP network. The system also includes a remote facility having a statistical multiplexer in communication with the IP network. The remote facility includes a compression system controller configuring the statistical multiplexer and at least one of the first plurality of receiving circuit modules and at least one of the second plurality of receiving circuit modules to form a multicast group so that at least one of the first plurality of encoded signals and at least one of the second plurality of encoded signals are multiplexed together with the statistical multiplexer to form an output signal.

International Classification:

H04N 7/20

US Classification:

725 71

Abstract:

A system and method for remotely collecting signals includes a local collection facility comprising a plurality of primary receiving circuit modules comprising a first receiving circuit module. The first receiving circuit module receives a first channel signal and forms a first encoded signal. The system further includes a remote facility having a multiplexer, and a router routing the first encoded signal to the multiplexer. The remote facility generates an output signal in response to the first encoded signal. A monitoring system receives an error signal from the first receiving circuit module. The router routes the error signal of the first receiving circuit module to the monitoring system. The system also includes a back-up receiving circuit module. The router routes the first channel signal to the back-up receiving circuit module to form a second encoded signal. The monitoring system monitors the second encoded signal. The router routes the second encoded signal at the local collection facility to the multiplexer at the remote facility in response to monitoring the second encoded signal. The remote facility forms the output signal in response to the second encoded signal.

International Classification:

F21K 9/237
F21V 23/06
F21V 29/77

Abstract:

An LED light module comprises an emitting portion; at least one LED package; a back cover; and an end cap. The emitting portion defines a first curved surface. The first curved surface extends a first length along a cylindrical axis defined by the LED light module. The back cover defines a second curved surface extending the first length along the cylindrical axis. The first curved surface and the second curved surface define a perimeter of the LED light module. In a cross-section of the LED light module taken in a plane substantially perpendicular to the cylindrical axis, the perimeter is substantially ovular, elliptical and/or tear-drop shaped. The end cap is substantially ovular, elliptical and/or tear-drop shaped, and comprises a coupling element configured to electrically and/or mechanically couple the LED light module to a subsequent LED light module or to a fixture.
