    Abstract: A sound projection apparatus for a video display device having left and right speakers, first and second ambience speakers, and an amplifier having a right channel and left channel. In this system, connection of the left channel to a speaker produces a left signal; the right channel to a speaker produces a right signal; the left and right channels to ambience circuitry produces an ambience channel; the ambience channel to the positive input of the first ambience speaker produces a first ambience signal and the ambience channel to the negative input of the second ambience speaker produces a second ambience signal. The left and right speakers are forward facing, projecting sound directly from the television to a viewer. The first and second ambience speakers are side or rearward facing, projecting sound indirectly to the viewer. The projection apparatus may be formed as a single cohesive unit, within or near the television.

    Abstract translation: 一种用于具有左右扬声器，第一和第二氛围扬声器以及具有右声道和左声道的放大器的视频显示装置的声音投影装置。 在该系统中，左声道与扬声器的连接产生左信号; 扬声器的右声道产生正确的信号; 左右通道到环境电路产生一个氛围通道; 第一氛围扬声器的正向输入的氛围通道产生第一环境信号，并且到第二氛围扬声器的负输入的环境声道产生第二环境信号。 左右扬声器向前，从电视直接投影到观看者。 第一和第二氛围扬声器是侧面或后面的，间接地向观看者投射声音。 投影装置可以形成为电视机内或附近的单个内聚单元。

    Abstract: A privacy-enable mobile phone case. The privacy-enabled case includes a privacy housing and a sliding element. The sliding element is slidingly coupled to the privacy housing and configured to secure a mobile device having one or more front facing camera(s), one or more rear facing camera(s), and one or more microphone(s). The one or more rear facing camera(s) and the one or more front facing camera(s) are covered when the sliding element is in a closed position by the privacy housing and cannot capture imagery, and the one more microphone(s) are covered in the closed position by the privacy housing thereby obstructing the recording of sound. The one or more rear facing camera(s) and the one or more front facing camera(s) are uncovered when the sliding element is in an open position and can capture imagery, and the one more microphone(s) are uncovered in the open position and can record sound.
