20140353180 | CARRIER AND PACKING CASE USING THE SAME - A carrier and a packing case using the same for a portable electronic device having a rear surface and a side surface are provided, wherein the carrier comprises a rear plate, a frame and at least a supporting component. The rear plate has a first inner surface fitting the rear surface and a first outer surface opposite thereto, and the frame surrounds the rear plate and has a second inner surface fitting the side surface and a second outer surface respectively surrounding the first inner and outer surfaces. The supporting component is pivoted to the first and/or second outer surfaces. The supporting component can be received in the frame by being rotated toward the rear plate and attached on the first outer surface, and support the portable electronic device to stand up by being rotated away from the rear plate and extended out of the frame. | 12-04-2014 |

20150049423 | KEYBOARD MODULE CAPABLE OF SUPPORTING A PORTABLE ELECTRONIC DEVICE - The present invention discloses a keyboard module capable of supporting a portable electronic device. The keyboard module includes a keyboard base and a supporting mechanism, and the supporting mechanism is disposed on the keyboard base. A containing space is formed inside the supporting mechanism, and the supporting mechanism includes at least one track and a supporting device. The at least one track is disposed in the containing space, and the supporting device is slidably disposed inside the containing space. The supporting device slides along the at least one track to extend outside the containing space to a supporting position for supporting the portable electronic device. | 02-19-2015 |
20150131580 | Large-Scale Fading Coefficient Estimation in Wireless Massive MIMO Systems - Efficient algorithms for estimating LSFCs with no aid of SSFCs by taking advantage of the channel hardening effect and large spatial samples available to a massive MIMO base station (BS) are proposed. The LSFC estimates are of low computational complexity and require relatively small training overhead. In the uplink direction, mobile stations (MSs) transmit orthogonal uplink pilots for the serving BS to estimate LSFCs. In the downlink direction, the BS transmits either pilot signal or data signal intended to the MSs that have already established time and frequency synchronization. The proposed uplink and downlink LSFC estimators are unbiased and asymptotically optimal as the number of BS antennas tends to infinity. | 05-14-2015 |

20150364385 | IN SITU ETCH COMPENSATE PROCESS - A method includes performing an etching on a mask layer to form an opening in the mask layer. The mask layer is a part of a wafer. The method further includes measuring a lateral size of the opening, comparing the lateral size of the opening with a specified range, and performing a compensation etch to compensate for a difference between the lateral size and the specified range. After the compensation etch, a target layer of the wafer is etched to extend the opening into the target layer. | 12-17-2015 |

20110277910 | Methods for Making Elastic Laminate - A method for making an elastic laminate includes providing adhesive on each of two sides of a highly porous foil to form a polygonal reticulate adhesive film which includes a plurality of polygonal adhesive dots spaced from one another by a plurality of adhesive-free linear gaps, or which includes a plurality of hollow polygonal adhesive units connected to one another and each encloses a polygonal adhesive-free gap. Two sheets of elastic layers are adhered by the adhesive to the sides of the highly porous foil so that polygonal reticulate gaps exist between the highly porous foil and the elastic layer, providing a laminate with moisture-absorbing, permeable, quick drying, thermally insulating, and elastic properties. | 11-17-2011 |
