  • Patent number: 11227242
    Abstract: A method includes determining, based at least in part on sensor data about a worksite, first and second conditions associated with a location at the worksite. The method also includes determining, based at least in part on the first condition and the second condition, a first risk factor associated with a first portion of the worksite, the first portion including the location and area proximate the location and determining a second risk factor associated with a second portion of the worksite adjacent the first portion. The method may also include generating a graphical user interface comprising a graphical representation of the first portion of the worksite and the second portion of the worksite and visual indications of the risk factors. Further aspects may include controlling machines and/or electronic devices at the worksite when a value associated with the risk factors is greater than a threshold value.

  • Patent number: 10921139
    Abstract: A method includes determining a first task requiring one of a plurality of machines to traverse along a first route and determining a second task requiring the one of the plurality of machines to traverse along a second route. The method also includes determining a first route score for the first route, the first route score being at least in part indicative of a difficulty of traversing along the first route, and determining a second route score for the second route, the second route score being at least in part indicative of a difficulty of traversing along the second route. The method may also include receiving sensor data generated by a sensor associated with a first machine of the plurality of machines and determining, based at least in part on the sensor data, an alertness metric associated with an operator of the first machine.

  • Publication number: 20170098182
    Abstract: A performance monitoring system associated with a machine is provided. The system includes a sensor assembly configured to generate data of one or more parameters associated with an operation of the machine. The system further includes a controller communicably coupled to the sensor assembly. The controller is configured to determine a list of performance parameters associated with a performance of an operator while operating the machine. The controller selects a set of performance parameters from the list of performance parameters. The controller receives the data associated with the set of performance parameters from the sensor assembly. The controller compares the data associated with the set of performance parameters with respective predetermined thresholds. The controller evaluates the performance of the operator based on the comparison. Also, the controller displays a visual cue to the operator. The visual cue is indicative of the performance of the operator based on the evaluation.

  • Patent number: 8195365
    Abstract: An operator restraint system is provided. The operator restraint system includes a seatbelt payout sensor and a seatbelt buckle assembly. The seatbelt buckle assembly includes a housing and an alarm assembly. The alarm assembly includes at least one of a light source configured to generate a visible signal and an annunciator configured to generate an audible signal. A controller is associated with at least one of the seatbelt payout sensor and the alarm assembly. The controller is configured to receive from the seatbelt payout sensor a signal indicative of a length of a seatbelt that has been withdrawn, determine whether the length of the seatbelt that has been withdrawn is within a predetermined range, and control the alarm assembly to selectively generate at least one of the visible signal and the audible signal to remind an operator regarding employment of the seatbelt based on the determination.

  • Patent number: 8056940
    Abstract: A pipe connector comprises a tubular pin member having a frustoconical outer surface and a tubular box member having a frustoconical inner surface corresponding to the outer surface of the pin member and which overlies the frustoconical surface of the pin member when the members are fully engaged. The members are provided with inter-engageable annular projections and grooves on the said peripheral surfaces for axially locking the members together when they are fully engaged together. The projections and grooves are spaced apart along the surfaces. The inner tubular surface of the pin member and an outer tubular surface of the box member each include at least one of a recess and/or a protrusion/radially enlarged section which reduces and/or increases the thickness of the tubular wall along the length of the associated member so as to balance the displacement of the members at different points along the length thereof under injection pressure.
