Abstract:
This invention utilizes the principle of time domain reflectometry (TDR) to develop an improved apparatus and method for suspended solid concentration (SSC) measurement. The apparatus comprises a TDR sensing waveguide for stably determining an electromagnetic-wave (EM-wave) travel time and a temperature sensor. The TDR sensing waveguide and the temperature sensor are submerged in a suspension to detect the EM-wave travel time and the temperature. A temperature-corrected relationship between EM-wave travel time and SSC is found and used to estimate the SSC. Although TDR has been used for measuring soil moisture content and high SSC, its accuracy is not satisfactory for typical SSC monitoring. The present invention improves the accuracy of TDR in SSC measurement by providing the apparatus and method disclosed herein, which are not affected by an electrical conductivity of the suspension and particle sizes of suspended solids therein, and therefore meet the requirements of general engineering applications and environmental monitoring.

Abstract:
A high-precision absolute type encoder apparatus includes a controller electrically connected to an incremental type encoder and generating a control signal to the incremental type encoder, a comparator electrically connected to outputs of the incremental type encoder and generating first pulse signals, a latch unit electrically connected to outputs of the comparator and generating second pulse signals by latching the generating first pulse signals. When power failure occurs, the controller generates the control signal as successive pulses with predetermined period to drive the latch unit and the incremental type encoder. Therefore, the controller knows angular information of the incremental type encoder by counting the second pulse signals. The absolute angular information can be obtained by combining the angular information and an initial position after power failure.
Abstract:
By using a predetermined tree structure to map elements of messages in a non-XML protocol to elements of appropriately structured messages in a data interchange format that facilitates script access, web-based applications programmed in scripting languages may be allowed to bypass protocol translation servers and communicate directly with network elements that only use non-XML protocol messages.
