    • A projector system using a screen comprised of either a plurality of miniature, reflective, and concave or convex curved surfaces that are arranged in a pattern to create a screen surface for front projection, or a plurality of miniature, transparent, and curved convex or concave lenses that are arranged in a pattern to create a screen surface for rear projection, and a projector system with the pixel capacity to control the color and brightness focused onto many different subsections of each curved surface. Each curved lens or curved mirror surface is small enough so that when viewed from the viewing area, the lit and unlit areas seen within each individual curved surface blend together so that only the average brightness and color of each curved surface can be seen by a viewer. By controlling the subsections of each curved surface with focused light from a high resolution projector, the system can control the image the viewer sees in their left eye separately from their right eye and the viewer can see stereographic images without the need to wear filtering glasses. With inclusion of an external head tracking system, the left/right images for each subsection can be switched as needed when one or multiple viewers move their head or seating position within the viewing area.
    • 一种投影仪系统,其使用由多个微型的,反射的和凹的或凸起的曲面组成的屏幕,所述多个微型的,反射的和凹的或凸的曲面以图案排列以形成用于前投影的屏幕表面,或多个微型,透明和弯曲的凸或凹 以图案布置以形成用于后投影的屏幕表面的透镜,以及具有像素能力的投影仪系统,其将颜色和亮度控制在每个曲面的许多不同部分上。 每个弯曲的透镜或曲面镜面足够小,使得当从观察区域观察时,在每个单独的弯曲表面中看到的点亮和未点亮的区域混合在一起,使得只有观看者可以看到每个曲面的平均亮度和颜色 。 通过利用来自高分辨率投影仪的聚焦光控制每个弯曲表面的子部分,该系统可以控制观看者在其左眼中与其右眼分离的图像,并且观看者可以看到立体图像而不需要戴过滤眼镜。 包括外部头跟踪系统时,当一个或多个观看者在观看区域内移动其头部或座席位置时,可以根据需要切换每个小节的左/右图像。

    • An electronic circuit for converting higher-frequency output signals from a sensor into lower-frequency input signals for a discrete input wireless transmitter. The circuit includes a differential amplifier, a digital comparator, a digital frequency divider, and a transistor switch. The differential amplifier amplifies the sensor signals as a function of a frequency of the sensor signals. The digital comparator generates a square wave signal by comparing the amplified sensor signals to a fixed reference voltage. The digital frequency divider generates a lower-frequency signal by dividing the square wave signal. The transistor switch generates the lower-frequency input signals for the discrete input wireless transmitter by switching as a function of the lower-frequency signal from the digital frequency divider.
    • 一种用于将来自传感器的较高频率输出信号转换为用于离散输入无线发射机的较低频率输入信号的电子电路。 该电路包括差分放大器,数字比较器,数字分频器和晶体管开关。 差分放大器将传感器信号放大为传感器信号频率的函数。 数字比较器通过将放大的传感器信号与固定参考电压进行比较来产生方波信号。 数字分频器通过划分方波信号来产生低频信号。 晶体管开关根据来自数字分频器的低频信号的切换产生离散输入无线发射机的低频输入信号。
