A retractable bollard system for installation in a support surface that includes pavement includes a shell that when installed in the support surface extends below an upper surface of the pavement. The bollard system includes a post to be telescopically coupled to the shell. The post is axially movable relative to the shell selectively to an upper area and a lower area. The post extends farther above the shell when the post is in the upper area than when the post is in the lower area. The bollard system further includes a shock absorber to encircle the shell. The shock absorber is made of a polymeric material.
E01F 15/00 - Dispositions de sécurité pour ralentir, maintenir sur la route ou arrêter les véhicules à la dérive, p.ex. bornes de protection ou pieux garde-fous; Dispositions pour réduire les dommages occasionnés aux structures du bord de la route par l'impact de véhicules

Example seals for insulated doors are disclosed. An example seal for a door includes a first mounting rail and a second mounting rail spaced apart from the first mounting rail. The example seal further includes a flexible sheet extending between the first mounting rail and the second mounting rail. The flexible sheet is to be biased away from the first and second mounting rails to sealingly engage the door when the door is in a closed position.
E06B 7/22 - Dispositions d'étanchéité sur les battants ou les parties qui travaillent avec les battants par bourrelets souples, p.ex. en feutre ou en peluche, en bandes de métal souple
Dynamically configurable traffic controllers and methods of using the same are disclosed. An example apparatus includes a first display facing a first direction; a second display facing a second direction; a third display facing a third direction; and a processor, in response to a first input being received indicative of traffic approaching the first display and no traffic approaching the second display and the third display, the processor to cause the second display and the third display to display a first signal and for the first display not to display the first signal or a second signal, the first signal providing a first warning level, the second signal providing a second warning level greater than the first warning level, the first signal illuminatable on the second display, the second signal illuminatable on the second display, the first signal, when illuminated, disposed within a perimeter of the second signal, when illuminated.
An example cooling system for a datacenter is disclosed. The datacenter includes a plurality of computers arranged in a row within a building. The row of computers separates a cold aisle and a hot aisle. The row of computers defines an air passageway between the cold aisle and the hot aisle. The row of computers is associated with a top surface that is below and spaced apart from an overhead surface of the building to define a gap between the top surface and the overhead surface. The example cooling system includes an inflatable air duct to be disposed within the gap. The inflatable air duct has selectively an inflated state and a deflated state. The inflatable air duct filling more of the gap when the inflatable air duct is in the inflated state than when the inflatable air duct is in the deflated state.
Puncture resistant seals for loading docks are disclosed. An example weather barrier disclosed herein includes a canopy having a back end and a front end, where the back end is mountable to a wall above a doorway and the front end is to protrude forward from the wall when the canopy is mounted to the wall. A front bar is at the front end of the canopy and the front bar is horizontally elongate. A back curtain hangs from the front bar. The back curtain has an upper curtain edge attached to the front bar. The back curtain has a lower curtain edge that is at a lower elevation than an elevation of the upper doorway edge when the canopy is mounted to the wall. The back curtain has a curtain width. A front panel hangs in front of the back curtain. The front panel is less flexible than the back curtain. The front panel has a panel width that is approximately 50 to 80 percent of the curtain width. A space is interposed between and defined by the front panel and the back curtain.
Methods and apparatus for monitoring a dock leveler are disclosed. An example method for monitoring a loading dock includes determining if a door at a doorway of a loading dock is in an open position; determining if a vehicle is present at the doorway; determining if a body is present in a first area of the loading dock, the first area including a deck positioned adjacent the doorway; and determining if a body is present in a second area of the loading dock adjacent the doorway, the second area including only a portion of a deck adjacent the doorway.
