    • A balloon bounce game suitable for use indoors, includes a generally rectangular mat of flexible material for defining a playing surface, the mat having first indicia for defining a center line that divides the playing surface into two equal area play fields, and second indicia for defining score areas in each of the play fields. The mat is of such dimensions as to enable the mat to be placed on a floor indoors, and for a player located in a serve zone behind a far end of one of the play fields to hit or strike a balloon over the center line to bounce or land in a score field in the other one of the play fields. The form and positions of the indicia therefore make a vertical net unnecessary.
    • 适合在室内使用的气球反弹游戏包括用于定义游戏表面的大体上矩形的柔性材料垫,该垫具有用于限定将播放表面划分成两个相等区域游戏场的中心线的第一标记,以及用于定义 每个场地的得分区域。 垫子具有如下尺寸:使得垫可以放置在室内的地板上,并且对于位于一个游戏区域的远端的服务区域中的玩家在中心线上击打或击打气球以反弹 或者在另一个游戏场中的得分区域中登陆。 因此,标记的形式和位置使得不需要垂直网。

    • A system and method for producing a more accurate ventilation image, as compared to existing lung Fourier decomposition methods, and an image of ventilation dependent blood volume are provided. A time series of images depicting a subject's lungs during free-breathing are acquired and co-registered to a reference image. From the registration process, geometric information indicative proton density changes due to inhalation and exhalation of gas is obtained. This geometric information is used to correct the proton density values in the time series of image frames. These corrected proton density values are Fourier transformed to produce a Fourier spectrum, from which a signal peak occurring at the breathing frequency is extracted and Fourier transformed to produce a more accurate ventilation image. This more accurate ventilation image can be subtracted from a breathing frequency image produced by conventional lung Fourier decomposition methods to produce a ventilation dependent blood volume image.
    • 提供了与现有的肺部傅立叶分解方法相比,用于产生更准确的通气图像的系统和方法以及通气依赖血液量的图像。 获取在自由呼吸期间描绘受试者的肺的时间序列图像并共同登记到参考图像。 从注册过程中,获得指示由于吸入和气体呼气引起的质子密度变化的几何信息。 该几何信息用于校正图像帧的时间序列中的质子密度值。 这些校正的质子密度值被傅里叶变换以产生傅里叶谱,从其中提取在呼吸频率处出现的信号峰,并进行傅立叶变换以产生更准确的通气图像。 可以从由常规肺傅里叶分解方法产生的呼吸频率图像中减去更准确的通气图像,以产生通气依赖性血容量图像。

    • A visor for automotive use including a plurality of air directing channels for reducing the aerodynamic drag of the visor. The visor is formed from a single sheet of material and the channels are formed by flat bottomed depressions beginning near the front edge of the visor and becoming progressively deeper to a point near the back edge of the visor. From this point, the bottom of the depression abruptly rises back to the visor surface. The depressions have a maximum width near the front edge and taper to half this width near the back edge of the visor. The channels direct air from under the visor through openings formed between the visor and the vehicle and exhaust the air with essentially laminar flow.
    • 一种用于汽车用途的遮阳板,包括多个空气引导通道,用于减少遮阳板的气动阻力。 遮阳板由单张材料形成,通道由靠近遮阳板前边缘的平底凹陷形成,并逐渐变深到靠近遮阳板后边缘的一个点。 从这一点来看,凹陷的底部突然上升回遮阳板表面。 凹陷在前边缘附近具有最大宽度,并在遮阳板的后边缘附近逐渐变窄到该宽度的一半。 通道通过形成在遮阳板和车辆之间的开口将空气从遮阳板下方引导,并以基本层流排出空气。
