    • A button protecting structure is for an electronic product. The electronic product comprises a housing, a printed circuit board (PCB) installed in the housing, and a button module installed in the housing and touchable with the PCB to execute specific functions. The button module has a plurality of bridge sections in which one end of each bridge section is positioned in the housing. The button protecting structure comprises a connection unit and a stopping unit extended from the connection unit. The connection unit is detachably positioned in the housing and located at one side of the PCB. And, the stopping unit is extended and installed at a bottom of the PCB and positioned in a displacement path of each button. Whereby, a plurality of electronic elements or the PCB is prevented from being damaged and broken owing to an overdoing exerted force generated an accidental pressing on the button.
    • 按钮保护结构用于电子产品。 电子产品包括壳体,安装在壳体中的印刷电路板(PCB),以及安装在壳体中并可与PCB触摸以执行特定功能的按钮模块。 按钮模块具有多个桥接部分,每个桥接部分的一端位于壳体中。 按钮保护结构包括连接单元和从连接单元延伸的止动单元。 连接单元可拆卸地定位在壳体中并且位于PCB的一侧。 并且,止动单元被延伸并安装在PCB的底部并且定位在每个按钮的位移路径中。 由此,由于产生意外按压按钮的过度施加的力,防止了多个电子元件或PCB被损坏和破坏。

    • An adjusting apparatus comprises a base, and a supporting frame, a fixed plate, a sliding stand, and a carrier, which are sequential stacked on the base. An optical engine is fixed on the carrier. By rotating the adjusting device, the axis position of optical engine can be adjusted along sliding slots guided by bulges. By using arc surfaces of the sliding stand and the carrier, the adjusting apparatus clips and pushes the blocks of the carrier to adjust the left and right angle of inclination of optical engine. Therefore, the light beam provided by optical engine could project on a screen precisely and reach the optimum projection performance.
    • 一种调节装置,包括基部,以及依次堆叠在基部上的支撑框架,固定板,滑动支架和支架。 光引擎固定在载体上。 通过旋转调节装置,可以沿着由凸起引导的滑动槽来调节光学引擎的轴位置。 通过使用滑动支架和支架的弧形表面,调节装置夹紧并推动载体的块,以调节光学引擎的左右倾斜角度。 因此,由光引擎提供的光束可以在屏幕上精确投影并达到最佳投影性能。

    • A channel information feedback method adapted in a receiving end of a multiuser multiple input multiple output (MU MIMO) system has following steps. A subspace matrix and a magnitude matrix related to a transmitting end of the MU MIMO system are obtained according to a channel matrix corresponding to the receiving end. A first quantization is performed on the subspace matrix to generate a quantized subspace matrix. A second quantization is performed on an auxiliary information matrix to generate a quantized auxiliary information matrix, where the auxiliary information matrix is corresponding to the magnitude matrix and a residual subspace matrix, and the residual subspace matrix includes residual subspace information after the first quantization is performed on the subspace matrix. The quantized subspace matrix and the quantized auxiliary information matrix are fed back to the transmitting end through an uplink channel.
    • 适用于多用户多输入多输出(MU MIMO)系统的接收端的信道信息反馈方法具有以下步骤。 根据与接收端对应的信道矩阵,获得与MU MIMO系统的发送端相关的子空间矩阵和幅度矩阵。 对子空间矩阵执行第一量化以产生量化的子空间矩阵。 在辅助信息矩阵上执行第二量化以产生量化的辅助信息矩阵,其中辅助信息矩阵对应于幅度矩阵和残余子空间矩阵,并且残余子空间矩阵包括执行第一量化之后的残余子空间信息 在子空间矩阵上。 量化的子空间矩阵和量化的辅助信息矩阵通过上行链路信道反馈到发送端。
