Abstract: Example air duct assemblies include an air duct including a tubular sidewall that is pliable, the tubular sidewall defining an interior of the air duct, the air duct elongate in a longitudinal direction. Example air duct assemblies include a hoop disposable within the interior of the air duct, the hoop providing the sidewall with support in a radial direction that is substantially perpendicular to the longitudinal direction. Example air duct assemblies include a cable disposable within the interior of the air duct, the cable to extend along a longitudinal length of the air duct, the cable to engage the hoop to help support a weight of the hoop and the tubular sidewall.

Abstract: Example air duct assemblies include a pliable air duct supported such that the duct is maintained in a generally expanded shape even when the duct is deflated. In some examples, a series of hangers suspend the duct from one or more cables, tracks or other type of overhead support. The hangers are spaced apart and distributed over the length of the duct, and each one contributes in pulling the duct taut in the duct's longitudinal direction.

Abstract: An example vehicle alignment system includes a camera to detect the vehicle approaching a doorway of a loading dock. The camera to generate an image signal indicative of at least one of an angular orientation of the vehicle or a lateral position of the vehicle relative to a reference. A controller is to detect a deviation in the at least one of the angular orientation of the vehicle or the lateral position of the vehicle relative to the reference based on the image signal. A display is to generate an indication representative of the at least one of the angular orientation of the vehicle or the lateral position of the vehicle relative to the reference.

Abstract: Example vehicle alignment systems for use at loading docks are disclosed herein. An example vehicle alignment system includes a first arm extending a first distance from a wall of the loading dock, where the first arm is positioned adjacent a first lateral edge of a doorway of the loading dock. A first sensor is coupled to the first arm, where the first sensor is directed substantially perpendicular relative to a longitudinal axis of the first arm. The first sensor is to detect a first lateral distance between the first sensor and a first side surface of the vehicle. The first sensor to provide a first feedback signal representative of the first lateral distance. A second arm extends a second distance from the wall of the loading dock, where the second arm is positioned adjacent a second lateral edge of the doorway of the loading dock opposite the first lateral edge.

Abstract: Example vehicle alignment systems for use at loading docks are disclosed herein. An example vehicle alignment system includes a first switch positioned on a first lateral edge of a doorway of the loading dock. The first switch is to be engageable by a first side surface of the vehicle. A second switch is positioned on a second lateral edge of the doorway opposite the first lateral edge. The second switch to be engageable by a second side surface of the vehicle opposite the first side surface. A controller is to receive a first feedback signal from the first switch and a second feedback signal from the second switch. The controller is to compare the first feedback signal and the second feedback signal to detect a lateral deviation of the vehicle relative to a reference.

Abstract: Example vehicle alignment systems for use at loading docks are disclosed herein. An example vehicle alignment system includes an outer sensor pair to detect a surface of the vehicle. The outer sensor pair is to obtain a first feedback signal representative of an orientation of the detected surface relative to a reference as the vehicle approaches a doorway of the loading dock. An inner sensor pair is to detect the surface of the vehicle. The inner sensor pair is to obtain a second feedback signal representative of the orientation of the detected surface relative to the reference as the vehicle approaches the doorway of the loading dock. A controller is to detect a threshold deviation in the orientation of the detected surface of the vehicle relative to the reference based on at least one of the first feedback signal or the second feedback signal. A display is to vary an output signal in response to the detected threshold deviation in the orientation of the detected surface relative to the reference.

An example vehicle alignment system includes a sensor system to detect a surface of a vehicle, where the sensor system obtains a feedback signal representative of a spatial orientation of the detected surface relative to a reference as the vehicle approaches a doorway of the loading dock. A controller detects a threshold deviation in the spatial orientation of the detected surface of the vehicle relative to the reference based on the feedback signal. A display varies an output signal in response to the detected deviation in the spatial orientation of the detected surface relative to the reference.
