20110132424 | VIBRATION MEDIATED NETWORKS FOR PHOTOVOLTAIC ARRAYS - A system and method to optimize the overall power output of a photovoltaic solar array. The solar panels are connected to software adjustable power optimizing devices, which in turn are connected to a mesh network with individual router devices. The individual router devices will send and receive data packets by creating or detecting vibrations in a solid vibration conducting media (such as the solar power wiring) that connects the individual photovoltaic solar panels. Often at least one centralized control device is used to periodically request sensor data packets from the individual router devices and solar panels. The centralized control device will typically compute the proper adjustments for the individual adjustable power optimizing devices that will optimize the overall power output from the photovoltaic solar array. The control device will then send adjustment data packets back to the individual router devices through the mesh network, thus optimizing overall power output. | 06-09-2011 |
20110182583 | DISTRIBUTED CABLE MODEM TERMINATION SYSTEM - Distributed CMTS device for a HFC CATV network serving multiple neighborhoods by multiple individual cables, in which the QAM modulators that provide data for the individual cables are divided between QAM modulators located at the cable plant, and remote QAM modulators ideally located at the fiber nodes. A basic set of CATV QAM data waveforms may be transmitted to the nodes using a first fiber, and a second set of IP/on-demand data may be transmitted to the nodes using an alternate fiber or alternate fiber frequency, and optionally other protocols such as Ethernet protocols. The nodes will extract the data specific to each neighborhood and inject this data into unused QAM channels, thus achieving improved data transmission rates through finer granularity. A computerized “virtual shelf” control system for this system is also disclosed. The system has high backward compatibility, and can be configured to mimic a conventional cable plant CMTS. | 07-28-2011 |
20110185394 | METHOD OF CATV CABLE SAME-FREQUENCY TIME DIVISION DUPLEX DATA TRANSMISSION - Method of bidirectional Time Division Duplex (TDD) data transmission over the same RF frequency ranges of a CATV cable system. The system's slave modem clocks are time synchronized to the master clock of a master modem. The master-to-slave signal propagation times are determined and used to precisely schedule transmissions with de-minimis guard times. The frequency range may be chosen to be in the high frequency CATV range around 1 GHz to maximize backward compatibility with legacy systems, and this frequency may in turn be subdivided into multiple frequencies. In some embodiments, the CATV cable tree may be further partitioned into multiple TDD domains, and multiple local master modems, connected by a special-use optical fiber, may communicate with multiple local slave modems. The system may use MAP allocation schemes that may frequently reallocate TDD time slots and frequencies according to current or projected slave modem data needs. | 07-28-2011 |
20110225617 | COLLABORATIVE RECORDING NETWORK SYSTEM AND METHOD - Collaborative video recording method that allows a plurality of networked digital video recorder (DVR) devices to distribute the tasks of receiving and storing digital video content data. To do this, the invention defines a new type of point-to-point (P2P) overlay network, termed a “Fair Use P2P network” designed to facilitate networking among those DVR devices that have legally equivalent access to the same video program content. Here DVR devices will seek out peer DVR devices on the Fair Use P2P overlay network, and advertise their capabilities. A user's DVR, upon determining that its own resources to record the desired program are overly limited, will contact other DVR devices request remote recording and storage services. To view, the user's DVR sends messages to the one or more remote DVR units requesting playback of the stored program data. This data will then be streamed back to the user and replayed. | 09-15-2011 |
20110246471 | RETRIEVING VIDEO ANNOTATION METADATA USING A P2P NETWORK - A method of annotating video programs (media) with metadata, and making the metadata available for download on a P2P network. Program annotators will analyze a video media and construct annotator index descriptors or signatures descriptive of the video media as a whole, annotator scenes of interest, and annotator items of interest. This will serve as an index to annotator metadata associated with specific scenes and items of interest. Viewers of these video medias on processor equipped, network capable, video devices will select scenes and items of interest as well, and the video devices will construct user indexes also descriptive of the video media, scenes and areas of interest. This user index will be sent over the P2P network to annotation nodes, and will be used as a search tool to find the appropriate index linked metadata. This will be sent back to the user video device over the P2P network. | 10-06-2011 |
20110265140 | HFC CABLE SYSTEM WITH SHADOW FIBER AND COAX FIBER TERMINALS - System and method to extend the upstream data capacity of an HFC CATV system by extending a “shadow” optical fiber network deeper into the various CATV cable neighborhoods, with coax fiber terminals (CFT) spaced roughly according to the distribution of CATV active devices such as RF amplifiers. The CFT can intercept local upstream data from various neighborhood sub-regions and transform this upstream data into upstream optical data, thus relieving upstream data congestion in the 5-42 MHz CATV frequency region. The system can produce an order of magnitude improvement in upstream capability, while maintaining high compatibility with legacy HFC equipment. The CFT may exist in multiple embodiments ranging from low-cost “dumb” CFT to sophisticated CFT that can additionally provide GigE to the home (GTTH) service. Methods to maintain good compatibility with legacy CMTS devices, and methods to utilize DOCSIS MAP data for more efficient data transmission are also discussed. | 10-27-2011 |
