    • A method and apparatus for measuring acoustic energy applied to the head to detect increases in intracranial pressure. Acoustic eye patches are applied to a patient's eye or eyelid, and an ultrasonic sweep generator applies an acoustic signal across the patient's skull, the signal being swept across a predetermined range. The eye patches have piezoelectric film sensors for measuring the acoustic signal. In one embodiment the predetermined range is in the ultrasonic band and an analyzer determines from the output of the sensors a resonant frequency and a damping of acoustic amplitude at said resonant frequency, there being a correlation between said damping and intra cranial pressure. In another embodiment the predetermined range includes a range less than 20 kHz and the analyzer determines retinal artery pulsations, with pressure being applied to the eye until the pulsations disappear, such pressure being a measure of intra cranial pressure.
    • 一种用于测量施加到头部的声能以检测颅内压升高的方法和装置。 声眼补片应用于患者的眼睛或眼睑,超声波扫描发生器在患者的颅骨上施加声学信号,该信号被扫过预定范围。 眼贴具有用于测量声信号的压电膜传感器。 在一个实施例中,预定范围在超声频带中,分析器根据传感器的输出确定谐振频率和在所述共振频率处的声振幅的阻尼,所述阻尼和颅内压之间存在相关性。 在另一个实施例中,预定范围包括小于20kHz的范围,并且分析仪确定视网膜动脉脉动,其中施加压力施加到眼睛直到脉动消失,这种压力是颅内压的量度。

    • A papermaking fabric includes a series of repeat units, each of the repeat units including: a first set of top machine direction (MD) yarns; a second set of top MD yarns; a set of top cross machine direction (CMD) yarns interwoven with the first and second sets of top MD yarns; a set of bottom CMD yarns; and a set of pairs of MD stitching yarns interwoven with the top and bottom CMD yarns, each pair of MD stitching yarns sandwiching an immediately adjacent respective top MD yarn of the second set. The first and second sets of top MD yarns interweave only with the top CMD yarns. The top MD yarns of the first set interweave in a first sequence with the top CMD yarns in which the top MD yarns of the first set form a plurality of top side MD knuckles over the top CMD yarns, and the top MD yarns of the second set interweave with the top CMD yarns in a second sequence that differs from the first sequence that differs from the first sequence in that the top MD yarns of the second set form fewer knuckles than are present in the first sequence. Only stitching yarns interweave with the bottom CMD yarns.
    • 造纸织物包括一系列重复单元,每个重复单元包括:第一组顶部机器方向(MD)纱线; 第二组顶层MD纱线; 一组与第一和第二组顶部MD纱线交织的顶部横向(CMD)纱线; 一套底部CMD纱线; 以及与顶部和底部CMD纱线交织的一组MD缝合纱线,每对MD缝合纱线夹着紧邻第二组的顶部MD纱线。 第一组和第二组顶层MD纱线仅与顶部CMD纱线交织。 第一组的顶部MD纱线以第一组织的第一顺序交织,其中第一组的顶部MD纱线在顶部CMD纱线上形成多个顶侧MD关节,并且第二组织的顶部MD纱线 以与第一序列不同的第一序列的第二序列设置与顶部CMD纱线交织,因为第二组织的顶部MD纱线比第一序列中存在的指节节数更少。 只有缝合纱线与底部CMD纱线交织。

    • A wide area network (WAN) of vending machines connected to a host that builds a database of vending-related information received from the vending machines. Also, a communications system within each vending machine having a vending machine data acquisition unit and a multiple-communication-technology adapter to interface the data acquisition unit to multiple communication technologies including at least one wireless technology. Also, a data structure used to build the database, the data structure having data elements corresponding to an identity of a machine, recent and previous prediction information for the machine, and recent and previous refill-visit information for the machine, the elements being linked together. The multiple vending machines communicate with a communications concentrator via one of many communication technologies. The communications concentrator interfaces the multiple vending machines to a data warehouse that builds a database using the data structure mentioned above. The data warehouse is made available to one or more bottlers for analysis of individual vending machine routing needs and profitability.
    • 连接到主机的自动售货机的广域网(WAN)构建从自动售货机接收的与售货相关的信息的数据库。 而且,每个售货机内的通信系统具有自动售货机数据获取单元和多通信技术适配器,以将数据采集单元与包括至少一种无线技术的多种通信技术相接合。 此外,用于构建数据库的数据结构,具有与机器的身份相对应的数据元素的数据结构,用于机器的最近和之前的预测信息以及机器的最近和之前的再填充访问信息,所述元件被链接 一起。 多台自动售货机通过许多通信技术之一与通信集线器进行通信。 通信集中器将多台自动售货机连接到使用上述数据结构构建数据库的数据仓库。 数据仓库可用于一个或多个瓶装机,用于分析各个售货机路由需求和盈利能力。
