20080221711 | METHODS AND APPARATUS FOR DETERMINING CHARACTERISTICS OF PARTICLES - An instrument for measuring the size distribution of a particle sample by counting and classifying particles into selected size ranges. The particle concentration is reduced to the level where the probability of measuring scattering from multiple particles at one time is reduced to an acceptable level. A light beam is focused or collimated through a sample cell, through which the particles flow. As each particle passes through the beam, it scatters, absorbs, and transmits different amounts of the light, depending upon the particle size. So both the decrease in the beam intensity, due to light removal by the particle, and increase of light, scattered by the particle, may be used to determine the particle size, to classify the particle and count it in a certain size range. If all of the particles pass through a single beam, then many small particles must be counted for each large one because typical distributions are uniform on a particle volume basis, and the number distribution is related to the volume distribution by the particle diameter cubed. | 09-11-2008 |
20090048690 | Anomaly Anti-Pattern - A method is presented for representing anomalies to a process. These anomalies are represented in an anti-pattern, which depicts non-productive emergent information that describes activities that are detrimental to the progress of the process. The anti-pattern includes visually-coded areas that describe how severe the detrimental activities are to the process when combined. After the anti-pattern is created for the process, new non-productive emergent information for a current process is mapped onto the anti-pattern in the form of data patterns represented as visual fences. Appropriate steps are then taken to address the new non-productive emergent information, depending on the visually-coded area to which the new non-productive emergent information is mapped. | 02-19-2009 |
20130024015 | METHOD FOR CONTROLLING BUILDING AUTOMATIC CONTROLL DEVICE - The present disclose a method for controlling a building automatic control device comprising a CPU module including a main-CPU module and a sub-CPU module, a functional module and a host. The method comprises an initial operation step, a synchronization step, a conversion step, a restoring step and a reporting step. By the method, the CPU module which is duplicated to gain safety of a direction digital control (DDC) used in the building automatic control device operate continuously. | 01-24-2013 |
20140135948 | ELECTRONIC CONTROL APPARATUS AND CONTROL CHARACTERISTIC ADJUSTMENT METHOD FOR THE SAME - A standard characteristic which is an average characteristic of multiple samples is approximated in a polygonal-line fashion by first to third lines | 05-15-2014 |

20120046763 | METHOD AND SYSTEM FOR ROBUST ATTENUATION OF MECHANICAL RESONANCES USING A MULTI-RATE LOW PASS FILTER - A system for a providing a multi-rate digital low pass filter that attenuates high frequency resonances in a control signal. The filter described by a transfer function having a phase-advanced factor (or an approximation of phase-advanced factor) and a low pass filtering function; either cancels or avoids an unstable pole in the phase advanced factor at z=−1. | 02-23-2012 |
20150088279 | NORMALIZED PROCESS DYNAMICS - A sensing system includes a filter construction module that constructs a high pass filter for filtering sensor values indicative of a process variable, the filter construction module setting values for parameters of the filter based on a temperature value indicative of a temperature of the sensor that produced the sensor values. | 03-26-2015 |
20160056794 | CONTROL FACILITY WITH ADAPTIVE FAULT COMPENSATION - A control facility for controlling a controlled system experiencing a disturbance includes a front nodal point receiving a target value and an actual value outputted by the controlled system and supplying a difference value corresponding to a difference between the target value and the actual value to a compensation circuit. The compensation circuit supplies a frequency-filtered and time-delayed signal formed as the sum of the weighted difference value and a weighted feedback signal as an input to a controller for the controlled system. The sum of a filter delay time and of first and second propagation delays is an integer multiple of the cycle duration of the disturbance, and a sum of the filter delay time and the first propagation delay is an integer multiple of the cycle duration minus a propagation time, which elapses until a change in the target value causes a change in the actual value. | 02-25-2016 |
