    • A shutter for protecting an opening. The shutter comprising a plurality of horizontal curtain slats for covering the opening, wherein horizontal refers to a direction when viewing slats from a front surface, and wherein the curtain slats hang freely from a upper region of the opening; an upper transition slat movably affixed to a lower end of a first curtain slat; a lower transition slat movably affixed to an upper end of a second curtain slat; and a horizontal reinforcing member comprising at least an upper and a lower reinforcing slat, wherein the upper reinforcing slat is rotatably affixed to a lower end of the first transition slat and the lower reinforcing slat is rotatably affixed to an upper end of the second transition slat, and wherein the upper and lower reinforcing slats are rotatably joined.

    • The time difference of arrival for a signal received at two or more receiving sites as transmitted from a wireless communications device, is determined by a frequency domain technique. The constituent frequencies of the signals received at the two or more receiving sites are determined, including the phase, or a value representative of the phase, of each frequency component. The phase values for the same frequency are subtracted to yield a phase difference values as a function of frequency. The slope of the function represents the time difference of arrival for the wireless communications device signal as received at the two receiving sites. To determine the mobile location based on the determined time difference of arrival values, a seed or initial location is first assumed for the wireless communications device and the distance difference of arrival (the time difference of arrival multiplied by the speed of light) is calculated. The calculated time difference of arrival is then used to adjust the distance difference of arrival by continuously iterating the position of the wireless communications device until the calculated distance of arrival and the calculated time difference of arrival (as multiplied by the speed of light) are within a predetermined margin.
    • 由无线通信设备发送的在两个或多个接收站点接收的信号的到达时间差由频域技术确定。 确定在两个或多个接收站点处接收的信号的组成频率,包括每个频率分量的相位或表示相位的值。 减去相同频率的相位值,以产生作为频率的函数的相位差值。 功能的斜率表示在两个接收站点接收到的无线通信设备信号的到达时间差。 为了基于所确定的到达值的时间差来确定移动位置,首先假设无线通信设备的种子或初始位置,并计算到达距离的差距(到达时间差乘以光的速度)。 计算出的到达时差随后用于通过连续迭代无线通信设备的位置来调整到达距离,直到计算的到达时间和计算的到达时间差值(乘以光速)在...之内 一个预定的余量。

    • A device that causes a weapon to fire upon a target when the weapon is enabled by an operator, and when the weapon point of impact passes through a target or in a proximity thereto and when the target satisfies certain criteria as determined by one or more sensors/designations.
      This invention represents a significant paradigm shift. Some prior art (large scale) weapons automatically acquire/track/prioritize/target/fire upon targets without operator intervention (i.e. Phalanx). Most prior art weapons, especially but not limited to small arms, are manually aimed, and fire immediately upon an input (trigger pull, or equivalent) from the operator. The current invention is a novel approach which triggers the release of a round, multi-round burst, rocket, missile, or other projectile(s) when enabled by the operator, and when the target passes through the point of impact (or desired/computed proximity thereto), relieving the operator of the split second judgment in timing the release and/or cessation of such fire. The results intended include a reduction in off-target rounds fired, increased hit rate, conservation of ammunition, more effective targeting for non-motion-stabilized weapons (in particular small/medium arms), and the introduction of a backup mode for nominally motion-stabilized weapons which may allow effective operations when primary stabilization systems fail or are overwhelmed by dynamics.
      This invention is applicable (in embodiments of varying complexity) to weapons ranging from handheld pistols to the main (artillery) gun of a tank, a ship, or the cannon aboard an aircraft.
