Abstract: A vacuum pump and a control device are capable of accurately determining timing of rotor blade replacement by creating an index which allows a degree of fatigue of a rotor blade to be determined quantitatively and easily. A motor current value output from a motor drive control portion is input to a time count processing portion, and time in which a current value of a rotating body remains in a range of a stage is totalized for each stage of the current value in the time count processing portion. A rotor blade temperature value output from a rotor blade temperature measurement portion is also input to the time count processing portion. A one-minute average value of the rotor blade temperature value acquired by sampling is calculated. For each stage of the rotor blade temperature value, time in which the average value remains in a range of the stage is totalized.

The determined driver efficiency score may be compared to a reference efficiency score and/or efficiency scores of other drivers to rank the drivers.
Abstract: Systems and methods for controlling a vehicle using operational constraints, including friction estimates are disclosed. Friction estimation include estimating a tire-road coefficient of friction using bins and envelopes. Bounding envelopes are configured to ensure that stability of the vehicle is maintained. The friction estimate is used to define the bounding envelopes. Further, the bounding envelopes are received as feedback into the friction estimation, itself. Based on the bounding envelope, the friction estimation can be adjusted. Then, the adjusted friction estimation can be fed back to reshape the bounding envelopes. Multiple bins can be used to evaluate an operating range of friction. Each bin can be used to compare actual vehicle dynamics with expected dynamics based on the estimation using the range assigned to that bin. Multiple bins and multiple controllers can run in parallel to re-estimate friction considering the vehicle dynamics over time.

Abstract: A technique facilitates tracking and assessing a fatigue life of a tubing string utilizing, for example, estimation of cycles to failure when used in a wellbore operation. The technique may comprise initially determining a fatigue life of a tubing string. Additionally, the technique comprises utilizing a sensing device, e.g. a magnetic flux leakage (MFL) device, to monitor the tubing string. When an anomaly, e.g. a new defect, is detected by the sensing device, a new fatigue life of the tubing string is determined based on the change. The new fatigue life may be used to estimate a fatigue life in terms of cycles to failure.

Abstract: A digital signal generation assumes that a base frequency (the frequency with which the primitive phase angles are specified relative to) is equal to the carrier frequency for all relevant times. But this causes errors in the digital signals output to each array element transducer. Thus, it is necessary for the development of a signal generation system that is capable of producing a digital signal using the free selection of amplitude and phase. This is used to produce a substantially error-free signal that preserves the amplitude and phase relative to a constant base frequency while allowing the carrier frequency to vary.

Abstract: Systems and methods for triggering emergency mass notifications include an EMNS activation service, a plurality of activation premises devices, a plurality of EMNS provider services, and a plurality of event personnel devices. The EMNS activation service includes a universal translator module that receives an event trigger signal relating to an emergency event from one of the activation premises devices. The universal translator module translates the event trigger signal to event-specific EMNS protocols of the EMNS providers. The EMNS activation service communicates the event-specific EMNS protocols to the EMNS providers, and communicates event data to event personnel devices based on a list of event personnel devices to be notified of an emergency event. An activation premises device includes a housing event with trigger controls for creating the event trigger signal, wherein these event trigger controls are inaccessible to users in the absence of an authorized access or an emergency access.
