    • An apparatus for detecting a spread spectrum signal in a wireless signal environment includes at least one antenna for receiving spread spectrum signals, such as UMTS signals, from a signal source in the wireless signal environment. In one embodiment, a detection circuit is configured for correlating a code in signal received by the apparatus with a set of possible codes for spread spectrum signals in order to detect the existence of a spread spectrum signal. In another embodiment, a detection circuit is configured for obtaining at least one reference frame of data from a received signal. The detection circuit is further operable for correlating a segment of the reference frame with a repeated segment of at least one subsequent frame of data in order to detect the existence of a spread spectrum signal. A repeater might incorporate such an apparatus wherein the variable gain of the repeater is adjusted based upon the correlation and the detection of a spread spectrum signal.
    • 一种用于在无线信号环境中检测扩频信号的装置包括至少一个天线,用于从无线信号环境中的信号源接收诸如UMTS信号的扩频信号。 在一个实施例中,检测电路被配置为将由装置接收的信号中的码与用于扩频信号的一组可能码相关,以便检测扩频信号的存在。 在另一个实施例中,检测电路被配置为从接收到的信号获得至少一个参考数据帧。 检测电路还可操作用于将参考帧的段与至少一个后续数据帧的重复段相关,以便检测扩频信号的存在。 中继器可以结合这样的装置,其中基于扩频信号的相关性和检测来调整中继器的可变增益。

    • A system for treating a surface to prevent or limit offensive odors and/or microbiological activity and improve indoor air quality includes electrostatically charged particles of anatase titanium dioxide and a substrate or surface on which these particles are received. The electrostatic charging of the particles, in conjunction with the substrate being oppositely charged, provides a self-leveling effect to the particles. The particles may be incorporated into an HVAC system defined by ductwork in which untreated air including organic matter flows, is treated, and is ejected as clean air. Methods of treating surfaces or fluids containing organic matter include providing electrostatically charged particles of anatase titanium dioxide and contacting the organic matter therewith to initiate photocatalytic oxidation processes in which the organic matter is broken down into less offensive constituents such as carbon dioxide and water.
    • 用于处理表面以防止或限制恶劣气味和/或微生物活性并改善室内空气质量的系统包括锐钛矿型二氧化钛的静电带电粒子和其上接收这些颗粒的基底或表面。 颗粒的静电充电与基板相反地带电提供了对颗粒的自流平效果。 颗粒可以结合到由管道系统限定的HVAC系统中,其中未处理的空气包括有机物流动,被处理,并作为清洁空气喷射。 处理含有有机物质的表面或流体的方法包括提供锐钛型二氧化钛的静电带电颗粒并使其与有机物质接触以引发光催化氧化过程,其中有机物被分解成较少令人反感的组分如二氧化碳和水。

    • An intraluminal medical device having axially adjacent segments connected by at least one strain concentrating bridge. The axially adjacent segments remain connected during delivery to an intended treatment site. After delivery, at least one of the at least one strain concentrating bridge may yield to separate at least two of the axially adjacent segments, if subjected to sufficient dynamic loading in the area within which the device is emplaced. The intraluminal device is ideally comprised of biocompatible metal materials and the at least one bridge is also comprised of such biocompatible metal materials, wherein the at least one strain concentrating bridge has a threshold level of strain less than that of the axially adjacent segments. Changing materials or changing dimensions of the at least one strain concentrating bridge can alter the threshold level of strain of the at least one bridge. Ideally the at least one strain concentrating bridge yields to disconnect the axially adjacent segments when subjected to prescribed loading conditions. The strain concentrating bridge may include a notched strain riser, a thinned portion, or a slotted portion that receives protrusions.
    • 具有通过至少一个应变集中桥连接的轴向相邻段的管腔内医疗装置。 轴向相邻的段在输送到预期的治疗部位期间保持连接。 在输送之后,如果在装置放置的区域中经受足够的动态载荷,则至少一个应变集中桥中的至少一个可以屈服以分离至少两个轴向相邻的段。 管腔内装置理想地由生物相容的金属材料组成,并且至少一个桥还包括这种生物相容性金属材料,其中至少一个应变集中桥具有小于轴向相邻段的应变阈值水平。 改变材料或改变至少一个应变集中桥的尺寸可以改变至少一个桥的应变的阈值水平。 理想地,当经受规定的负载条件时,至少一个应变集中桥产生断开轴向相邻的段。 应变集中桥可以包括凹口应变提升器,变薄的部分或接收突起的开槽部分。
