    • A portable entertainment system for a vehicle includes a portable housing, a transceiver, a processor, a memory, and a rechargeable battery. The transceiver communicates through RF signals with Portable Electronic Devices (PEDs) operated by vehicle passengers. The rechargeable battery supplies power to the transceiver, the processor, and the memory. The memory is coupled to the processor and includes entertainment content and further includes computer readable program code that causes the processor to communicate a list, of at least some of the entertainment content available in the memory, to the PEDs. A content selection message is received through the transceiver from one of the PEDs that requests communication of a selected one of the entertainment content identified in the list. The selected entertainment content is communicated through the transceiver to the PED. The transceiver, the processor, and the memory are enclosed within the portable housing.
    • 一种用于车辆的便携式娱乐系统包括便携式外壳,收发器,处理器,存储器和可充电电池。 收发器通过RF信号与车载乘客操作的便携式电子设备(PED)进行通信。 可充电电池为收发器,处理器和存储器供电。 存储器耦合到处理器并且包括娱乐内容,并且还包括使处理器将存储器中可用的至少一些娱乐内容的列表传达给PED的计算机可读程序代码。 通过收发器从其中一个PED接收到内容选择消息,该PED请求在列表中标识的娱乐内容中选择的一个娱乐内容的通信。 所选择的娱乐内容通过收发器传送到PED。 收发器,处理器和存储器被封装在便携式外壳内。

    • A flame detector consisting of a first infrared radiation detector for detecting radiation from combustion of hydrocarbon and other carbon containing compounds in conjunction with a second infrared radiation detector for distinguishing radiation from other sources such as modulated sunlight, reflections, artificial as well as natural hot objects, illuminating light sources, and arc welders. The flame detector uses two electronic circuits following the first infrared detector such that a fire is sensed by either of the two circuits depending on its size, one circuit being optimized for flicker frequencies present in a large fire while the second circuit simultaneously checks for optical signals at flicker frequencies dominant in a smaller fire. The two electronic outputs along with the output of the second infrared detector are digitally processed and analyzed for spectral and temporal characteristics to distinguish the presence of a real fire from that of various false alarm sources. The flame detector is provided with digital serial communications so as to output its status, permit changes in the programming of operating parameters and modes and permit troubleshooting via remote control.
    • 一种火焰探测器,由第一红外辐射探测器组成,用于检测来自碳氢化合物和其它含碳化合物的燃烧的辐射与第二红外辐射探测器的结合,用于区分辐射与其他光源,例如调制的阳光,反射,人造和自然热物体 照明光源和电弧焊机。 火焰检测器使用跟随第一红外检测器的两个电子电路,使得两个电路中的任一个根据其大小感测到火,一个电路针对存在于大火中的闪烁频率进行优化,而第二电路同时检查光信号 在较小的火中占优势的闪烁频率。 数字处理和分析两个电子输出以及第二个红外线检测器的输出,以分析频谱和时间特征,以区分真实火灾的存在与各种虚假警报源的存在。 火焰检测器配有数字串行通信,以便输出其状态,允许更改操作参数和模式的编程,并通过远程控制进行故障排除。

    • Apparatus for the optical detection of flames or explosions, having an optical structure to perform continuous optical path monitoring of the optical window receiving the optical radiation, to ensure against the buildup of radiation absorbing or scattering materials. A light source internal to the housing illuminates a straight optically transmissive quartz or sapphire rod that protrudes through the housing beyond the optical window. The protruding tip of the light rod is beveled and metallized on the bevel to provide internal reflection of the light from the source, the angle of the bevel being such that the reflected light on exiting the light rod illuminates the optical window and the optical detector behind it, thereby providing a test for the cleanliness of the optical window. This optical technique for checking the cleanliness of the optical viewing element can be utilized by other optical instruments including imaging arrays, surveillance cameras and weapons.
