Abstract: Techniques are described for correlating entity identification information with refuse containers being serviced by a refuse collection vehicle (RCV). Location data can be collected by location sensor(s) on the RCV at a time when a triggering condition is present, such as a time when a lift arm is operating to empty a refuse container into the hopper of the RCV. The location data can be provided as input to an algorithm that estimates a container location through a vector offset to account for the distance and direction of the RCV lift arm relative to the location sensor in the RCV. The container location can be correlated with parcel data to determine the parcel that the container was on or near to when it was serviced, and the customer or other entity associated with the parcel can be correlated to the particular container based on the analysis.

Abstract: A proprotor system for a tiltrotor aircraft includes a yoke having a plurality of blade arms each having an inboard pocket. Each of a plurality of bearing assemblies is disposed at least partially within one of the inboard pockets. Each of a plurality of inboard beams is disposed at least partially between a centrifugal force bearing and a shear bearing of each bearing assembly and has a proprotor blade coupled thereto. Each of a plurality of latch assemblies selectively couples one of the bearing assemblies to the yoke. Each latch assembly is rotatable relative to the yoke between an engaged position wherein the latch assembly is engagable with one of the bearing assemblies to couple the bearing assembly to the yoke and a disengaged position wherein the latch assembly is disengaged from the respective bearing assembly enabling installation and removal of the respective bearing assembly relative to the respective pocket.

Abstract: The subject technology provides for removing a source of delay in a phase-locked loop (PLL) by causing the output rising edge to occur at the same time as the input rising edge. The subject technology replicates the amount of delay experienced along an input reference signal path to the PLL as close as possible using a same circuit configuration and bias circuits as in the input reference signal path. For example, a timing alignment circuit containing a replica circuit adds compensation delay to a negative feedback loop signal to match the feedback loop delay with the reference path delay. The delay of the reference signal path is estimated and added into the replica circuit. The delay characteristics of these two paths negate one another such that the phases of the input reference signal and the feedback loop signal become phase-locked at the input to the PLL.

Abstract: A technique facilitates assembly and deployment of a sand screen assembly string. The sand screen assembly string is constructed by providing sequential base pipe joints combined with corresponding alternate path tubes. The sequential base pipe joints are joined together in a manner which brings sequential, corresponding alternate path tubes into close proximity with each other at a location external to the sequential base pipe joints. The sequential, corresponding alternate path tubes are readily coupled together by a connector which is movably mounted along at least one of the alternate path tubes for movement into engagement with the other alternate path tube.
