20080252475 | Monitoring Method and Apparatus Using Asynchronous, One-Way Transmission from Sensor to Base Station - A monitoring system is disclosed, which includes a base station and at least one sensor unit that is separate from the base station. The sensor unit resides in a dormant state that uses no power, until it is awaked by the triggering of vibration-sensitive switch. Once awakened, the sensor may take a measurement, then transmit to the base station the measurement along with a time stamp of when the measurement was made. The sensor may optionally store the measured quantity and the time stamp for a particular length of time in a suitable storage device, such as with compact flash memory. The sensor transmits the measured quantity and the time stamp to the base station in an asynchronous manner. The transmission is initiated by the vibration-sensitive switch, not by the base station. The time stamp is encoded in a suitable manner, such as with an IRIG-B timing module. Once data is transmitted from the sensor to the base station, the sensor may return to its dormant state. Transmission between the sensor and the base station is one-way, so that the sensor does not receive any information from the base station. There may be multiple sensors for each base station, and the various sensors may optionally measure different quantities, such as current, voltage, single-axis and/or three-axis magnetic fields, that may correspond to physical quantities such as torsional strain, linear strain, temperature, ball valve cycles and linear voltage displacement transducer signals. The sensor may optionally include an energy harvester, such as a solar panel, for reducing and/or eliminating the drain on its battery. | 10-16-2008 |

20110291850 | MACHINE VIBRATION MONITORING - A system and method of monitoring vibrations, in a machine having a rotating element, where composite vibration signals are measured and filtered into discreet vector components associated with machine operating frequency. The filtered vectors are then evaluated to obtain a mean and standard deviation, whereupon a further value is obtained and compared to the prior values. Trip conditions may be set to initiate certain actions based on the meeting of the conditions. Additional data related to operating conditions of the machine may be analyzed in conjunction with the vibration data to be considered as providing a cause for vibration anomalies that may be observed. The operating, conditions of the machine may be displayed on a computer display in association with the discreet vector components, for example in a second level folder to the first level folder of the discreet vector components. | 12-01-2011 |

20140313043 | REMOVABLE STAND ALONE VIBRATION MONITOR WITH AUTOMATICALLY CONFIGURED ALARM THRESHOLDS - A user provides relevant information about the operating parameters of a machine to be monitored to a diagnostic instrument. The user also specifies a location of the machine to be monitored, an alarm level to be set, and the type of alert to be sent. The instrument then automatically generates appropriate an alarm threshold using a set of rules applied to the inputs. The instrument then transmits the alarm threshold to a removable stand-alone monitor. The stand-alone monitor acquires data about the machine, compares the date to the alarm threshold, and sends a user-specified alert when the alarm threshold has been reached. Using the diagnostic instrument and monitor, machines can be monitored for vibration, temperature, or a power parameter. | 10-23-2014 |
20140320298 | Method and Apparatus for Detection of Structural Failure - A detection system for identifying deterioration in a structure is provided that has acoustic sensors that receive acoustic emission waves. The acoustic emission wave detected by the acoustic sensor is identified as a hit. An analysis circuit is present that identifies an A state, a B state, and a C state. The B state has increased hit activity from the A state where a rate B is greater than a rate A by a factor of f1. The C state has increased hit activity from the B state where a rate C is greater than the rate A by a factor of f2. An alarm is activated when an amount of time that the C state is identified as being present reaches a value of TM, or alternatively when a threshold value based upon of the number of hits and time in the C state is reached. | 10-30-2014 |
