Abstract: Systems, methods, and apparatuses for worksite equipment path planning is provided. An example system may include an autonomous vehicle configured to operate a camera and position sensor to capture image data associated with a worksite. The system may also include a worksite analysis engine comprising processing circuitry configured to receive the image data of the worksite captured by the autonomous vehicle and generate a virtual layout of the worksite based on the image data. The worksite analysis engine may also receive equipment data and crew data, and generate a workflow based on the virtual layout, the equipment data, and the crew data. The workflow may include workflow assignments for each crew member at the worksite, each workflow assignment indicating a task, equipment to perform the task, and an equipment path for the task.

Abstract: A faucet lever safety lock prevents operation of various faucets by preventing use of the faucets' handles. The faucet lever safety lock may comprise one or more struts configured to locate one or more handle engagement devices at a faucet's handles when the faucet lever safety lock is assembled. The handle engagement devices engage to prevent their movement and operation. The faucet lever safety lock may be secured in an assembled configuration via a coupling device that ensures that the handle engagement devices maintain their relative position. The coupling device may be releasable to allow the faucet lever safety lock to be disassembled to allow operation of the faucet.

Abstract: A confined capping system provides a simple approach for compressive strength testing of high performance concrete specimens. The test specimen ends are capped with a conventional capping compound confined in steel rings larger in diameter than the specimen. The capped rings are compression tested in a conventional way. This method thus employs standard concrete laboratory testing equipment. An inexpensive customized capping apparatus may be used for preparing the specimen ends. The method ensures that confinement is provided to the cap without having to place tight controls on specimen end roughness prior to capping and on the cap thickness itself.

Abstract: Disclosed is a quartz tube for a furnace for processing semiconductor wafers. The furnace comprises:an elongated hollow body having opposed first and second ends and a longitudinal axis;an injector opening being formed in the first end, the injector opening including sidewalls which are spaced to slidably receive an elongated gas injector assembly through the opening; andan alignment jig received within the hollow body inwardly adjacent the first end and injector opening, the alignment jig including support means for engaging and aligning a gas injector with the injector opening to support a gas injector to emit gas substantially along the longitudinal tube body axis.
