摘要:
An electronic system comprises an enclosure, a printed circuit board in the enclosure, and a heat sink assembly comprising a holding member. The enclosure comprises a first panel and a second panel perpendicularly connecting with the first panel. The printed circuit board is mounted on the first panel of the enclosure. The heat sink assembly has a first end mounted on the printed circuit board for contacting a heat-generating electronic device on the printed circuit board, and a second end opposite to the first end. The holding member connects the second panel of the enclosure with the second end of the heat sink assembly.
摘要:
A method and apparatus for recovery from discontinuous reception desynchronization, the method having the steps of: determining a most recent time that an explicit message indicating a change from an old discontinuous reception period to a new discontinuous reception period was sent; adding to the most recent time that the explicit message was sent the old discontinuous reception period multiplied by an integer, where the integer is selected to ensure the results of the adding step occur after a present time; and sending a continuous reception command at the time found in the adding step.
摘要:
The present invention provides an engine exhaust gas purification device comprising a filter B provided in an exhaust passage (10) of an engine (1) for trapping particulate matter contained in the exhaust gas, a catalyst A for regenerating the filter B by burning the particulate matter trapped in the filter B, an EGR valve (8) provided in an EGR passage (7) linking the intake side and exhaust side of the engine 1, an injector (2) for injecting fuel into a cylinder, and control unit (20) for controlling the injector (2) and EGR valve (8). During regeneration of the filter B, the control unit (20) close the EGR valve (8) when fuel injection from the injector (2) is controlled to supply unburned fuel components to the catalyst A, and open the EGR valve (8) when no fuel is injected from the injector (2) upon a request for speed reduction or the like. In so doing, residual unburned fuel components in the EGR passage (7) are scavenged by air.

The present disclosure is directed to a system and method for operating a user agent (UA) and access device located within a communications cell according to a half-duplex (HD), frequency-division duplexing (FDD) protocol. The system and method are designed to accommodate a guard period (GP) between downlink (DL) and uplink (UL) communications from the UA, while addressing the loss of at least part of the DL communication before a subsequent UL subframe to accommodate the GP.

The invention further discloses compositions, polynucleotide constructs, transformed host cells, transgenic plants and seeds containing the Zea mays NFB2 regulatory polynucleotide sequences, and methods for preparing and using the same.
摘要:
The present invention relates to nucleic acid sequences from Xenorhabdus, and, in particular, to genomic DNA sequences, and to nucleotide sequences that encode insecticidal proteins from Xenorhabdus bovienii, strain Xs85831. The invention encompasses nucleic acid molecules present in non-coding regions as well as nucleic acid molecules that encode proteins, fragments of proteins, tRNA's, fragments of tRNA's, rRNA's, and fragments of rRNA's. In addition, proteins and fragments thereof and antibodies capable of binding specifically to the proteins are encompassed by the present invention. The invention also relates to methods of using the disclosed nucleic acid molecules, proteins, protein fragments, RNA's, and antibodies, for example, for gene identification and analysis, preparation of constructs, and protecting plants from insect infestations.
摘要:
A system of a telecommunications network is provided. The system includes a processor configured to promote preventing a detachment of a user equipment (UE) from the network by preventing deactivation of at least one default bearer between the UE and the network when at least one bearer between the UE and the network is to be deactivated based on a quality of service parameter.
摘要:
Materials and methods for fabricating and using negative index materials are disclosed. A negative index material comprises a three-dimensional volume including a bulk solution and a plurality of unit cells disposed in the bulk solution in a substantially random pattern. Each unit cell comprises a periodic hole array pattern on a substrate or a resonator formed on a first surface of a substrate, and a thin wire pattern formed on a second surface of the substrate. The combination of the unit cells in the bulk solution produces a negative effective permeability and a negative effective permittivity over a frequency band of interest for the three-dimensional volume. The negative index material may be used to focus radiation by directing an incident radiation at the negative index material and generating a focused radiation by a negative refraction of the incident radiation in the negative index material.
