Patent number: 10152524Abstract: Security on data storage and transport are important concerns on cloud computing. Wavefront multiplexing/demultiplexing process (WF muxing/demuxing) embodying an architecture that utilizes multi-dimensional waveforms has found applications in data storage and transport on cloud. Multiple data sets are preprocessed by WF muxing before stored/transported. WF muxed data is aggregated data from multiple data sets that have been “customized processed” and disassembled into any scalable number of sets of processed data, with each set being stored on a storage site. The original data is reassembled via WF demuxing after retrieving a lesser but scalable number of WF muxed data sets. In short, the WF muxed data storage solution enhances data security and data redundancy by, respectively, creating a new dimension to existing security/privacy methods and significantly reducing the storage space needed for data redundancy.Type: GrantFiled: July 29, 2013Date of Patent: December 11, 2018Assignee: SPATIAL DIGITAL SYSTEMS, INC.Inventors: Donald C.

In the fiber nodes, the received narrowcast signals are converted back to analog signals and combined with analog broadcast signals for transmission to the service groups.Type: GrantFiled: July 1, 2011Date of Patent: March 20, 2018Assignee: ARRIS Enterprises LLCInventors: Zoran Maricevic, Marcel F.

Patent number: 9894625Abstract: Methods and apparatus are provided for facilitating synchronization between a base station (BS) and a user equipment (UE) in a mobile communication system. The UE receives a synchronization signal originated by the BS. The synchronization signal is encoded with a selected cyclically permutable (CP) codeword. Encoding of the synchronization signal is facilitated by a repetitive cyclically permutable (RCP) codeword derivable from the selected CP codeword. The RCP codeword has a plurality of codeword elements each associated with a value, the value of at least one codeword element in the RCP codeword being repeated in another codeword element position in the RCP codeword. And the synchronization signal is decoded in accordance with repetitive structure of the RCP codeword.Type: GrantFiled: December 19, 2014Date of Patent: February 13, 2018Assignee: Huawei Technologies Co., Ltd.Inventor: Fredrik Berggren

Patent number: 9887795Abstract: Processing a received optical signal in an optical communication network includes equalizing a received optical signal to provide an equalized signal, demodulating the equalized signal according to an m-ary modulation format to provide a demodulated signal, decoding the demodulated signal according to an inner code to provide an inner-decoded signal, and decoding the inner-decoded signal according to an outer code. Other aspects include other features such as equalizing an optical channel including storing channel characteristics for the optical channel associated with a client, loading the stored channel characteristics during a waiting period between bursts on the channel, and equalizing a received burst from the client using the loaded channel characteristics.Type: GrantFiled: April 10, 2016Date of Patent: February 6, 2018Inventors: Alexander Soto, Walter Soto

Patent number: 9887855Abstract: A virtual converged cable access platform (CCAP) system and method for hybrid fiber CATV (HFC) cable networks. The system uses a new type of digital optical fiber node configured to receive optical fiber data packets, and reconstitute the optical data packets into RF waveforms suitable for injection into the system's CATV cable. The system replaces the legacy HFC head end with a simplified “virtual head end”. The system's virtual head end operates using a new type of virtual CCAP controller and virtual CCAP software that in turn controls high performance edge routers. Much of the intelligence of running the HFC cable system is managed by the controller software, while the edge router manages the interface between the CATV portion of the system and outside networks. The system can handle even legacy CATV RF signals by appropriate conversion operations, while reducing power and space needs, and improving operational flexibility.Type: GrantFiled: December 22, 2014Date of Patent: February 6, 2018Assignee: Alcatel-Lucent USA, Inc.Inventor: Shlomo Selim Rakib

Patent number: 9860820Abstract: A system and method for providing wireless network communications between a plurality of remote devices and a site controller are provided. Each network and the site controller communicates using a communications protocol adapted to allow remote devices and the site controller to independently control the communication path for transmissions sent by each device. In some embodiments, remote devices can collect and store information about other remote devices and available communication paths for optimum data transmission. Also, in some embodiments, remote devices can quickly join a preexisting network by communicating with a site controller and/or other remote devices. Other embodiments are also claimed and described.Type: GrantFiled: September 6, 2016Date of Patent: January 2, 2018Assignee: SIPCO, LLCInventor: David Petite

Patent number: 9860481Abstract: The present invention provides an information processing method and an electronic device. The method is applied in a first electronic device and comprises: obtaining a first data; obtaining P frame images based on the first data, where P is an integer larger than or equal to 1; obtaining a second data based on a data channel with a second electronic device; obtaining Q frame images based on the second data, where Q is an integer larger than or equal to 1; generating a video stream of M frame images based on the P frame images and the Q frame images, where M<P+Q. With the present invention, based on the video data of both communication parties, the video or voice data can be clipped based on a processing rule to generate a video stream, such that the resulting video stream can be more compact and continuous and have a better viewing effect. The generated video stream can be used as a communication record for the communication parties which is convenient for the user to view or play as desired.Type: GrantFiled: March 14, 2014Date of Patent: January 2, 2018Assignees: BEIJING LENOVO SOFTWARE LTD., LENOVO (BEIJING) LIMITEDInventor: Yan Ke
