    • A low fluid sensor for an internal combustion engine. The sensor includes a base with helically threaded post and a float slidably mounted on the post. The float rotates about the post as it moves longitudinally along it. In the preferred embodiment, eccentric mounting of the assembly along with its lobe shape act in concert with the pitch of the screw threads and fluid viscosity to dampen the buoyant movement of the float against fluid turbulence. At a predetermined level a latch spring on the float contacts an ignition circuit terminal and grounds the engine ignition circuit. A catch holds the float at the predetermined level, preventing engine starting, so that the sensor may only be reset by addition of fluid and re-insertion of the dipstick.
    • 用于内燃机的低流体传感器。 传感器包括具有螺旋螺纹柱的底座和可滑动地安装在柱上的浮子。 当浮体沿其纵向移动时,浮子围绕柱旋转。 在优选实施例中,组件的偏心安装及其凸起形状与螺纹螺距和流体粘度一致,以抑制浮子的浮力运动抵抗流体湍流。 在预定水平上,浮子上的闩锁弹簧接触点火电路端子并使发动机点火电路接地。 捕捉器将浮子保持在预定水平,防止发动机起动,使得传感器只能通过添加流体和重新插入量油尺来重置。

    • To prevent poaching of an Internet Protocol (IP) set top box (STB) asset or similar network computing device from one system operator to another, code executing in the IP STB not only authenticates downloaded software images using a public key provided in a serial-number assigned digital certificate, but also confirms that the serial number appears on a signed whitelist, or does not appear on a signed blacklist. The code executing in the STB further preferably enforces a rule that only the authority that signed the already-loaded whitelist/blacklist may replace it with a new list. Such a sticky whitelist/blacklist ensures that if the STB boots or resets in a new network, the existing authentication list will not be replaced by a list that is valid for a new or different network, and, as a result, that new software code images will not be authenticated.
    • 为了防止从一个系统运营商偷窃互联网协议(IP)机顶盒(STB)资产或类似网络计算设备到另一个系统运营商,在IP STB中执行的代码不仅使用串行端口中提供的公钥来验证下载的软件映像, 号码分配的数字证书,但也确认序列号显示在签名的白名单上,或不显示在签名的黑名单上。 在STB中执行的代码进一步优选地实施规则,只有签署已经加载的白名单/黑名单的权限可以用新的列表来替换它。 这种粘性白名单/黑名单确保如果STB在新网络中启动或重置,则现有的身份验证列表将不会被对新的或不同的网络有效的列表所替代,因此,新的软件代码 图像将不会被认证。
