Individualized gain control of remote uplink band paths in a remote unit in a distributed antenna system (DAS), based on combined uplink power level in the remote unit
Individualized gain control of remote uplink band paths in a remote unit in a wireless communication system based on combined uplink power level in the remote unit.

Aspects of this disclosure include the selection of a scan order for both significance map coding and level coding, as well as the selection of contexts for entropy coding consistent with the selected scan order. This disclosure proposes a harmonization of the scan order to code both the significance map of the transform coefficients as well as to code the levels of the transform coefficient. It is proposed that the scan order for the significance map should be in the inverse direction (i.e., from the higher frequencies to the lower frequencies). This disclosure also proposes that transform coefficients be scanned in sub-sets as opposed to fixed sub-blocks. In particular, transform coefficients are scanned in a sub-set consisting of a number of consecutive coefficients according to the scan order. |

A display backlight comprises an edge-lit lightguide having an array of light out-coupling structures to enable light to escape from the lightguide at the location of the light out-coupling structures.

Time-resolving sensor using shared PPD+SPAD pixel and spatial-temporal correlation for range measurement
A Time-of-Flight (TOF) technique is combined with analog amplitude modulation within each pixel in a pixel array using multiple Single Photon Avalanche Diodes (SPADs) in conjunction with a single Pinned Photo Diode (PPD) in each pixel. A SPAD may be shared among multiple neighboring pixels. The TOF information is added to the received light signal by the analog domain-based single-ended to differential converter inside the pixel itself. The spatial-temporal correlation among outputs of multiple, adjacent SPADs in a pixel is used to control the operation of the PPD to facilitate recording of TOF values and range of an object. Erroneous range measurements due to ambient light are prevented by stopping the charge transfer from the PPD—and, hence, recording a TOF value—only when two or more SPADs in the pixel are triggered within a pre-defined time interval. An autonomous navigation system with multi-SPAD pixels provides improved vision for drivers under difficult driving conditions. |

Boomerang join: a network efficient, late-materialized, distributed join technique
Embodiments comprise a distributed join processing technique that reduces the data exchanged over the network. Embodiments first evaluate the join using a partitioned parallel join based on join tuples that represent the rows that are to be joined to produce join result tuples that represent matches between rows for the join result.

To further conserve network bandwidth, embodiments perform an additional record-identifier shuffling phase based on the respective sizes of the projected columns from the relations involved in the join operation. Specifically, the result tuples are shuffled such that transmitting projected columns from the join relation with the larger payload is avoided and the system need only exchange, over the network, projected columns from the join relation with the smaller payload. |

In order to solve the problem, a multiband antenna according to the present invention is provided with: a conductive reflection plate; a frequency selective surface that is disposed so as to at least partially face the conductive reflection plate, that transmits therethrough electromagnetic waves in a first frequency band, that reflects thereon electromagnetic waves in a second frequency band that is a higher frequency band than the first frequency band, and that has a plurality of openings; a plurality of first antenna elements that are disposed in a region sandwiched between the conductive reflection plate and the frequency selective surface and that are tuned to a first frequency included in the first frequency band; and a plurality of second antenna elements that are disposed on a surface opposite the surface of the frequency selective surface facing the first antenna elements, that are fed through feeders passing through the openings, and that are tuned to a second frequency included in the second frequency band. |

Switch assembly, switch assembly control method, controller, and base station
A switch assembly, a switch assembly control method, a controller, and a base station are disclosed, which relate to the wireless communications field. The switch assembly includes: a mechanical normally open switch (102), a movable contact (104), and a controller (106), where the controller (106) is connected to a phase shifter (108) of a remote electrical tilt unit, and the movable contact (104) is arranged to move with a driving rod (1082) of the phase shifter (108); when the movable contact (104) reaches a specified position, the mechanical normally open switch (102) is triggered to close. A prior-art problem that interference is caused to a base station signal because an integrated semiconductor chip radio frequency switch is a nonlinear element and a problem that installation is relatively difficult because a volume of a relay switch is relatively large are resolved. |

Reducing noise in phased-array signals from receivers located at different locations
In a computerized method to reduce noise in phased-array signals from a set of receivers at different locations, time-series are received from the receivers, which time-series form phased-array signals. The time-series are ordered based on the different locations of the receivers and spatially phased series are obtained from the ordered time-series. Each of the spatially phased series obtained includes a series of signal values that are spatially phased. A noise component is identified in each of the spatially phased series obtained and removed from the spatially phased series to obtain denoised series. Related receiver systems and computer program products are also provided. |
