  • Patent number: 10110012
    Abstract: A system and a control method of a mobile micro-grid are provided. The mobile micro-grid system includes a renewable energy source and a non-renewable energy source which are in a container. The control method includes supplying the renewable energy source as a primary power supply to an external load; and determining whether the electricity of the renewable energy source is sufficient. If the electricity of the renewable energy source is sufficient, then the renewable energy source provides electricity to the external load; if the electricity of the renewable energy source is not sufficient, then the renewable energy source and non-renewable energy source provide electricity to the external load. If an external power source, which is a renewable-energy-type power source, is connected to the mobile micro-grid system, then the renewable energy source and external power source work as the primary power supply.

  • Patent number: 10031816
    Abstract: The disclosed computer-implemented method for healing images in deduplication storage may include (i) detecting that a data segment stored within deduplication storage is corrupted by executing an algorithm on the data segment to generate a numerical identifier for the data segment and determining that the numerical identifier does not match a previously stored numerical identifier for the data segment, (ii) checking, during a backup operation, whether a digital fingerprint of a data segment of an image being backed up matches a digital fingerprint of the corrupted data segment that was taken prior to corruption and that is already stored within the deduplication storage, and (iii) appending the data segment from the image being backed up to a container that already contains the corrupted data segment rather than replacing the corrupted data segment. Various other methods, systems, and computer-readable media are also disclosed.

  • Patent number: 9913267
    Abstract: In legacy systems such as 3rd Generation Partnership Project (3GPP) releases 8 to 10, the control channel is transmitted using the first few Orthogonal Frequency Division Multiplexing (OFDM) symbols in a subframe. The limited control channel capacity will impact the system performance in future releases as more and more User Equipments (UEs) will be scheduled in a subframe with technologies such as MulitUser-Multiple Input Multiple Output (MU-MIMO) and Coordinated Multipoint (CoMP) transmission being enhanced or introduced. A new Enhanced Control CHannel (E-CCH) is necessary to be designed, which will use the resource in the Physical Downlink Shared CHannel (PDSCH) in the legacy systems. The E-CCH will support UE-specific DeModulation Reference Signal (DMRS) based transmission and receiving. However, the configuration of DMRS for E-CCH is necessary to be known to UE in prior. This invention discloses multiple methods in which DMRS is configured for E-CCHs and respective eNB and UE behaviors.
