The method comprises measuring vibrations of the hydrocyclone at a selected frequency within a predetermined frequency range; comparing a characteristic of the measured vibrations at the selected frequency with a plurality of values representing transitions between different operational states of the hydrocyclone to identify a current operational state of the hydrocyclone; and generating an adjustment setting to change the identified current operational state to the desired operational state, where the adjustment setting increases or decreases a pumped fluid parameter.

Abstract: A physical location marking device has a primary survey pole, an upper portion atop of which is survey equipment, and a lower portion to which is attached a pole support tip. A marking application holder may be exteriorly attached to the primary survey pole via a rotationally adjustable alignment adapter and a vertically adjustable adapter that together provide up to six degrees of freedom to the marking application holder so a marking applicator (SP) within the marking application holder applies a point marking product to a specific physical location for ground surveying, construction, and other physical location marking needs. The marking application holder may be interior to the primary survey pole. The pole support tip may be conically expanding towards ground with a marking template holder within the pole support tip holding a marking template which has a cut-pattern to apply symbol markings.

Abstract: A cup holder assembly includes a body that defines a cup-receiving cavity and an aperture that extends through a side wall of the body, a first bracing feature and a second bracing feature, each of which is coupled to the body and positioned outside of the cup-receiving cavity, and a retention finger. The retention finger includes a first portion that extends into the cup-receiving cavity through the aperture, a first engagement feature coupled to the first portion and pivotably engaged with the first bracing feature, and a second engagement feature coupled to the first portion and engaged with the second bracing feature. The retention finger is operable to move via pivotal movement of the first engagement feature relative to the first bracing feature.

Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for using a surfel map to generate long range localization. One of the methods includes obtaining, for a particular location of a vehicle having a camera and a detection sensor, surfel data including a plurality of surfels.

It is determined that a region of interest for detecting objects for a vehicle planning process is outside a detectable region for the detection sensor. In response, it is determined that the image data for the region of interest matches surfel color data for the surfels corresponding to the region of interest. In response, the vehicle planning process is performed with the region of interest designated as having no unexpected objects.

Abstract: A parking facility access management system having a sensing device communicatively connected to the internet and to a mechanism for providing access to a parking facility. A mobile device is communicatively connected to the sensing device while in proximity to the sensing device, and also communicatively connected to the internet while not in proximity to the sensing device. As the mobile device enters proximity to the sensing device, the mobile device communicates exclusively with the sensing device and not the internet. In some embodiments, as the mobile device enters proximity to the sensing device, the mobile device sends a signal to the sensing device to alert the mechanism for providing access to provide access to the parking facility.

Abstract: Methods, systems, and computer-readable media for offline evaluation of machine learning models with noise reduction are disclosed. A trigger computation system generates a plurality of experimental requests. The experimental requests do not represent unmodified requests received from clients in a production environment. At least one parameter value varies for individual ones of the experimental requests. The trigger computation system provides the experimental requests to a first machine learning model and a second machine learning model. The first machine learning model and the second machine learning model produce a set of results based at least in part on the experimental requests. The trigger computation system determines a reduced set of results for which the first machine learning model and the second machine learning model differ. An evaluation of the first machine learning model or the second machine learning model is performed using the reduced set of results.
