Publication number: 20130016975Abstract: The present invention is directed towards a frequency modulated (FM) burst mode optical system that allows optical signals having a common wavelength provided by a plurality of FM burst mode optical transmitters to be passively combined onto a single optical fiber. A single FM optical receiver receives the combined signals and processes them accordingly. Each FM burst mode optical transmitter includes an FM modulator, is carrier detect circuit and a laser. The FM modulator modulates a carrier signal, such as a 1.21 GHz signal, with received reverse electrical signals. When a subcarrier signal is detected o the carrier detect circuit, the laser is turned and the frequency modulated carrier signal is used to intensity modulate a laser to provide an optical signal. Due to the burst-mode transmission of optical signals, the optical signals can be passively combined and transmitted to a single optical receiver.Type: ApplicationFiled: September 17, 2012Publication date: January 17, 2013Applicant: SCIENTIFIC-ATLANTA, LLCInventor: SCIENTIFIC-ATLANTA, LLC

Publication number: 20110280396Abstract: The present invention is suitable for use in a multi-encrypted system that dynamically allocates stream identifiers in a secondary overlay stream depending upon the identifiers in a primary encrypted stream. The primary encrypted input stream is monitored to determine the presence of all identifier values. Once the identifier values are determined, the values are stored in an allocation table and marked as ‘in-use’ to ensure that these identifier values are not allocated to any of the secondary overlay streams. The primary encrypted stream is monitored and the allocation table is updated continuously to detect any changes or conflicts to the identifier values, and the secondary overlay streams are dynamically updated accordingly.Type: ApplicationFiled: July 26, 2011Publication date: November 17, 2011Applicant: Scientific-Atlanta, LLCInventors: Neil B.

Patent number: 7941918Abstract: A spring-loaded device is installed into a node housing at a predetermined location. The predetermined location is selected to correspond to another predetermined location into which a stinger may be installed. These predetermined locations on the node housing are selected to further correspond to a predetermined internal location of an RF interface connector. A conducting pin of the RF interface extends through a dielectric between a nail head shaped end, which provides electrical connection with the stinger projection, and an end soldered to a PCB of the amplifier. The amplifier may be installed and the node housing closed before the stinger and spring-loaded device are installed into the housing. This facilitates installation of the stinger into the housing without having to open the housing and remove the amplifier. External threads on the spring-loaded device facilitate installation thereof, but a unique torque is not required therefor.Type: GrantFiled: June 17, 2008Date of Patent: May 17, 2011Assignee: Scientific-Atlanta, LLCInventors: Steven C.
