What are the most effective ways to manage project risks remotely?
Three things that worked for me: 1. Build trust in the team so that they can push back if they need to. 2. Get early wins so that you get into habit of winning. 3. Identify risks and plan time for iterations there. Add more management oversight while working on milestones that involve risk. 4. Break a problem down into steps and identify bottlenecks.

Apparatus and method for identifying health indicators for rolling element bearings
Issued US9618037B2
A method includes receiving an input signal containing information associated with a rolling element bearing and/or a piece of equipment containing the rolling element bearing. The method also includes decomposing the input signal into a frequency-domain signal and determining at least one family of frequencies corresponding to at least one failure mode of the rolling element bearing. The method further includes generating a reconstructed input signal using the at least one family of…
A method includes receiving an input signal containing information associated with a rolling element bearing and/or a piece of equipment containing the rolling element bearing. The method also includes decomposing the input signal into a frequency-domain signal and determining at least one family of frequencies corresponding to at least one failure mode of the rolling element bearing. The method further includes generating a reconstructed input signal using the at least one family of frequencies and the frequency-domain signal. In addition, the method includes determining, using the reconstructed input signal, an indicator identifying an overall health of the rolling element bearing. The indicator could be determined using a baseline signal associated with either (i) normal operation of the rolling element bearing and/or the piece of equipment or (ii) defective operation of the rolling element bearing and/or the piece of equipment (where a severity of the defective operation will increase over time).

System and method for blind fault detection for rotating machinery
Issued USPTO
A system includes more sensors configured to measure one or more characteristics of rotating equipment and a blind fault detection device. The blind fault detection device includes an input interface configured to receive at least one input signal from the one or more sensors. The blind fault detection device also includes a processing unit configured to identify a fault in the rotating equipment using the at least one input signal. The blind fault detection device further includes an output…

Asset-specific equipment health monitoring (EHM) for industrial equipment using standardized asset models
Issued US8896437B2
A system includes at least one sensor and an equipment health monitoring (EHM) unit. The at least one sensor is configured to measure one or more characteristics of an asset, where the asset includes a piece of equipment. The EHM unit includes at least one sensor interface configured to receive at least one input signal associated with the asset from the sensor(s). The EHM unit also includes at least one processing unit operable to be pre-configured to identify a specified fault in the asset…

Handheld apparatus and method for determining the reliability of a network connection at a site
Issued US20100062735A1
A method includes receiving wireless signals from a wireless network at a handheld device located at a specified site. The wireless signals are associated with a network connection at the specified site. The method also includes determining one or more metrics related to a reliability of the network connection at the specified site. In addition, the method includes determining that a class of application or device is supported by the network connection using the one or more metrics. The one or…
A method includes receiving wireless signals from a wireless network at a handheld device located at a specified site. The wireless signals are associated with a network connection at the specified site. The method also includes determining one or more metrics related to a reliability of the network connection at the specified site. In addition, the method includes determining that a class of application or device is supported by the network connection using the one or more metrics. The one or more metrics could include signal strength, bandwidth, latency, average number of channels available, number of routing elements visible, and/or average latency. Determining that the class of application or device is supported by the network connection could include determining that each of the one or more metrics is suitable for the class of application or device based on a criticality of the class of application or device.
