20130257673 | Mobile Communication Coverage Distribution System in Corridor and Coupled Radiation Unit - A mobile communication coverage distribution system in corridor is used for mobile communication signal coverage in corridor environment. The system includes a radio frequency (RF) cable arranged along longitudinal direction of the corridor and intended for signal transmission and having a plurality of spaced access nodes; a signal source for transmitting signal to from the RF cable or receiving signal to from the RF cable; a number of coupled radiation units corresponding to each access node and used to realize signal coverage in a limited range near the access node, said signal being transmitted across the RF cable. The mobile communication coverage distribution system in corridor according to the invention has simple structure, low cost, is convenient in construction and has reliable performance. | 10-03-2013 |
20150102971 | Bi-Polarized Broadband Annular Radiation Unit and Array Antenna - A bi-polarized broadband annular radiation unit, for being installed on a metal reflective plate thus constituting a communication antenna and defining an annular construction by two pairs of orthogonally polarized dipoles, includes two pairs of orthogonally polarized dipoles, each dipole comprising two symmetrical unit arms of a single line sheet shape, one end of a unit arm being facing to a corresponding end of the other unit arm, and a distal end of each unit arm of at least one pair of dipoles is provided with a loading line; and a plurality of balun arms feeding power to and supporting respective dipoles, each balun arm including two parallel balun lines, and the top ends of the two balun lines being connected with corresponding ends of the two unit arms of a corresponding dipole. Each unit arm and the balun line and/or loading line connected to the same unit arm are made by sheet metal stamping forming process or casting process. | 04-16-2015 |

20130035241 | KEY GENES, MICRORNAS, OTHER NON-CODING RNAS AND COMBINATION THEREOF FOR IDENTIFYING AND REGULATING THE PLURIPOTENT STATUS OF CELLS - Key genes, microRNAs, other non-coding RNAs and a combination thereof for identifying and regulating pluripotency of cells are provided. The key genes, microRNAs, other non-coding RNAs and a combination thereof are highly expressed in full pluripotent stem cells but are significantly suppressed or silenced in partially pluripotent stem cells. The genes, microRNAs and other non-coding RNAs are those of a chromosome imprinted Dlk1-Dio3 region located on the long arm of mouse chromosome 12, and are homologous genes, microRNAs and other non-coding RNAs having 70-100% homology with them in genomic syntenic regions of other mammals. Also provided are uses of the genes, microRNAs, other non-coding RNAs and combination thereof in identifying the pluripotent status of stem cells and regulating pluripotency of cells; in typing stem cells; regulating pluripotency of cells, pluripotent states and levels of cells; treating diseases; and developing drug targets for tumor treatment and antitumor drugs. | 02-07-2013 |
