    • Techniques are disclosed that allow for the detection, identification, and direction finding of wireless emitters in a given multipath environment. For example, the techniques can be used to detect and identify a line of bearing (LOB) to an IEEE 802.11 emitter in a building or in an open field or along a roadside. In some cases, multiple LOBs can be used to geolocate the target emitter if so desired. The techniques can be embodied, for instance, in a handheld device that can survey the target environment, detect an IEEE 802.11 emitter and identify it by MAC address, and then precisely determine the LOB to that emitter. In some cases, a sample array of response data from the target emitter is correlated to a plurality of calibrated arrays having known azimuths to determine the LOB to the target emitter.

    • The pipe coupling has an annular flange member having a tapered inner surface portion and a plurality of holes therethrough. Bolts project through the holes. A pipe-engageable collet is mounted in the flange member and has a tapered outer surface portion engaged with the tapered inner surface portion. An annular, retainer element engages a surface of the flange member from which the bolts project and overlaps an outer peripheral portion of the seal back-up member and has a plurality of holes therethrough which are in substantial alignment with the holes through the flange member. The bolts project through the holes in the retainer element whereby the bolts and the retainer element are retained in position by virtue of their mutual interengagement and the seal back-up member and collet are retained in position by virtue of the engagement of the retainer element with the seal back-up member. The coupling can be relatively easily handled and easily manipulated into position even in a confined space without risk of the back-up member, the collet, and/or the bolts becoming inadvertently disengaged.
    • 管接头具有环形凸缘构件,其具有锥形内表面部分和穿过其中的多个孔。 螺栓通过孔突出。 管接合夹头安装在凸缘构件中,并且具有与锥形内表面部分接合的锥形外表面部分。 环形保持器元件接合凸缘构件的表面,螺栓从该凸缘构件的表面突出并与密封件支撑构件的外周部分重叠,并且具有穿过其的多个孔,该多个孔通过凸缘构件与孔大致对准。 螺栓突出通过保持器元件中的孔,由此螺栓和保持器元件由于它们的相互接合而保持在适当位置,并且密封件支撑构件和夹头由于保持器元件与 密封件备件。 联轴器可以相对容易地处理,并且即使在密闭空间中也容易操纵到位,而不会造成备用构件,夹头和/或螺栓无意中脱离的风险。

    • A variable indicia sign for use in retail merchandising and the like which has a plurality of windows through which shopper sees indicia such as price. The indicia in each window is formed on a continuous tape, the position of which is controlled externally and which can be varied by the merchandiser to accurately and selectively bring into view the desired information. The structure of the device allows for easy adjustment by authorized personnel but effectively precludes customers from varying the indicia.
