Patent number: 7424403Abstract: A low power vibration sensor and wireless transmitter system has one or more sensors that sense parameters of a machine including vibration and produces dynamic signals representing the sensed parameters. The system converts the signals to a digital format, digitally filters the signals, and processes the signals. A processor determines a plurality of levels, which represent the characteristics of the signal such as the peak value of a predetermined set of data points of the digital signal. Together, the levels comprise a PeakVue waveform. The processor determines the peak level value for the PeakVue waveform. Also, a true root-mean-square is calculated as the signal is received at the processor. The peak level and the RMS value are communicated wirelessly by a communication module to a control protocol network such as a daisy chain HART or Fieldbus protocol network. The system power supply and the communication module power supply are separate and allow for low power operation.Type: GrantFiled: January 26, 2007Date of Patent: September 9, 2008Assignee: CSI Technology, Inc.Inventors: James C.

Patent number: 5430301Abstract: Method and Apparatus for measuring and classifying individual neplike entities in a textile fiber sample is disclosed. The apparatus includes a fiber sample processor which takes a supply of fiber samples, separates and individualizes the individual entities of the fiber sample and provides the individualized entities to an airflow. The airflow directs the entities through a sensor volume which utilizes electro optical sensors to generate characteristic signals corresponding to the entity passing through the sensor volume. These signals are then analyzed to determine if the entity passing through the sensing volume was a nep and further classify neps by their type. Thus, a neplike entity could be classified as either a polyester nep, a fiber nep or a seed coat fragment and further may be classified as a mature entity or an immature entity.Type: GrantFiled: January 11, 1993Date of Patent: July 4, 1995Assignee: Zellweger Uster, Inc.Inventors: Frederick M.
