    • Polymer slurries of ultrahigh molecular weight polyalpha-olefins are made stable toward settling, separation and agglomeration by surface treatment with a combination of wax and optional relatively high-density particulates. The selection of the surface coating acts not only as an anti-blocking agent, or partitioning aid to keep the tacky polymer particles separated, but also provides the suspended polymer particle with a density that matches the carrier. This prevents separation of the slurry components over time. Such materials, ultimately used as pipeline additives to reduce the fluid drag and increase the volumetric throughput, can be stored and shipped for extended periods of time without degradation of the slurry quality. Upon injection into the pipeline, the polymer particle dissolves quickly, unhindered by the coating.

    • Three-way call detection is an important component of correctional facility telephone equipment because it helps restrict calling access by certain persons to certain restricted telephone numbers. Various three-way call detection methods exist, but all of these implementations suffer from one major limitation—the detection accuracy is not as high as is desired by the industry. The present invention improves detection accuracy, using “steganography.” Steganography involves hiding one set of data or signals within another signal or carrier in such a way that its presence is virtually imperceptible to the end recipient, and potential even the originator of the carrier signal. Television producers use steganographic methods to encode data in video signals for security, distribution monitoring, piracy-control, and other reasons. The present invention involves a device that connects to a telephone, either at the line or handset interfaces, and produces a known signal that is steganographically hidden within the user's normal voice signal. Detection equipment, residing at another location, monitors signals on telephone calls and tests for the presence of the hidden signal or data generated by the invention. Once detection is achieved, appropriate action, such as terminating or recording the call, may be taken. Improved accuracy is achieved by choosing the appropriate hidden signal(s)—ones that never occur in the course of normal conversation and never get generated by telephone company equipment. Once detected, the presence of the signal guarantees the call was made to the restricted party from a particular phone line.
    • 三通呼叫检测是惩教设施电话设备的重要组成部分,因为它有助于限制某些人的呼叫接入某些受限电话号码。 存在各种三路呼叫检测方法,但是所有这些实现都受到一个主要限制 - 检测精度不如业界期望的那么高。 本发明使用“隐写术”来提高检测精度。隐写术涉及将另一个信号或载体中的一组数据或信号隐藏在另一个信号或载体中,使得其存在对于最终接收者实际上是不可察觉的,甚至潜在甚至载波信号的发起者 。 电视制作者使用隐写方法对视频信号中的数据进行编码,以进行安全性,分发监控,盗版控制等原因。 本发明涉及一种在线路或手机接口处连接到电话的设备,并且产生隐式地隐藏在用户的正常语音信号内的已知信号。 驻留在另一位置的检测设备通过电话监视信号并测试本发明产生的隐藏信号或数据的存在。 一旦检测到,可以采取适当的动作,例如终止或记录呼叫。 通过选择在正常对话过程中永远不会发生的永久不会由电话公司设备产生的适当的隐藏信号来提高准确性。 一旦被检测到,信号的存在就保证了从一个特定的电话线路向限制方发出呼叫。

    • Disclosed herein is a three-way call detection system and method for detecting the addition of a third party to a pre-existing telephonic connection between a first party and a second party. The system includes a meter for measuring the amplitude of a line voltage of a telephonic connection between two parties, a first filter to remove a frequency band from the line voltage, a white noise generator for generating a low level white noise signal in the removed frequency band, a coupler for combining the white noise signal with the filtered signal, to create an additive line voltage, a second filter that passes only a portion of the additive line voltage including at least a portion of the white noise signal, and a processor for monitoring the passed signal for a shift in amplitude level associated with the addition of a third party to the connection.
