A method of cyclic etching, comprising: (A) depositing, prior to cyclically etching a substrate through a mask opening, a pre-etch protection layer conformally over the mask, sidewalls of the mask defining the mask opening; and an exposed portion of the substrate exposed through the mask opening, the pre-etch protection layer deposited to a first thickness; and (B) cyclically etching the substrate by: (i) depositing a protection layer in the opening of the mask, the protection layer deposited to a second thickness that is less than half of the first thickness; (ii) etching through a portion of the protection layer disposed on the substrate and etching the substrate; and (iii) repeating (i) and (ii) until an end point is reached.

無線耳機結構

本創作為一種無線耳機結構，其係包含一支撐架、一聽筒、一黏貼部、一控制模組，以及一訊號處理模組。支撐架之一側設置聽筒，另一側活動式設置黏貼部。控制模組設置於支撐架之一端，訊號處理模組設置於支撐架內部，並與聽筒、控制模組電性連接；其中，黏貼部為一可撓式軟性材質，其撓折貼附於一人體之外耳，並使聽筒鄰近耳朵。於此，透過一音源裝置與無線耳機結構進行無線通訊，俾使聽筒發聲傳遞至人體耳朵，並可透過控制模組調節聽筒之音量大小。

貨幣集存裝置

本創作為一種貨幣集存裝置，其所具有之存錢筒功能係可藉由一辨識元件偵測投入一投幣孔之至少一貨幣面額，亦可經由一中央處理模組儲存置放於一殼體內部之一容置空間中的複數個貨幣總額，而於殼體外之一顯示螢幕上顯示；又，本創作之貨幣集存裝置另分別設置一喇叭、至少一插埠以及一鬧鐘於殼體之各部位，插埠與一電子設備(例如MP3播放器)連接，而可於喇叭輸出音源，並可透過一控制模組調節喇叭之音量、樂曲選擇、操作鬧鐘之時間校正、定時、鬧鈴開/關、鬧鈴樂曲更換，以及貨幣總額校正/歸零等功能。

Method for extracting spectral information of a substance under test

A method for extracting spectral information of a substance under test includes: identifying a pixel region A(x, y) occupied by an object under test from a hyperspectral image acquired; extracting a specular reflection region Aq and a diffuse reflection region Ar from the pixel region A(x, y), and calculating a representative spectrum Iq(ω) of the specular reflection region Aq and a representative spectrum Ir(ω) of the diffuse reflection region Ar, respectively; by comparing each element in the representative spectrum Iq(ω) of the specular reflection region Aq with each element in the representative spectrum Ir(ω) of the diffuse reflection region Ar, separating information of a light source from spectral information of the object to obtain a first spectral invariant C(ω). This method does not require additional spectral information of the light source, which improves the analysis efficiency.
