Abstract: An apparatus is provided to test valves. The apparatus includes an actuation mechanism having an actuator that seals a valve of a combustion chamber of an engine. The apparatus further includes a flow control device that controls a flow of a pressurized fluid to the combustion chamber. The apparatus further includes a plurality of sensors having a first sensor and a second sensor. The first sensor is disposed in an inlet port of the combustion chamber to detect a first flow rate of the pressurized fluid in the inlet port. The second sensor is disposed in an exhaust port of the combustion chamber to detect a second flow rate of the pressurized fluid in the exhaust port. The apparatus further includes a notification device configured to generate an alert based on the detected first flow rate and the detected second flow rate.

Abstract: Various implementations provide a view of a 3D environment including a portal for viewing a stereo item (e.g., a photo or video) positioned a distance behind the portal. One or more visual effects are provided based on texture of one or more portions of the stereo item, e.g., texture at cutoff or visible edges of the stereo item. The effects change the appearance of the stereo item or the portal itself, e.g., improving visual comfort issues by minimizing window violations or otherwise enhancing the viewing experience. Various implementations provide a view of a 3D environment including an immersive view of a stereo item without using portal. Such a visual effect may be provided to partially obscure the surrounding 3D environment.

Abstract: Various embodiments of a voltage detection device and of related safety systems are provided. In various embodiments, the voltage detection device is configured to couple to safety headwear, such as via the one or more housing(s) of the voltage detection device coupling directly to the safety headwear or the voltage detection device coupling to an adaptor mounted to the hard hat.

Abstract: Fiber optic assemblies are used to link transceivers carrying a signal from the transmitter portion of one transceiver to the receiver portion of another transceiver. The fiber optic assemblies have multi-fiber fiber optic connectors with a multi-fiber ferrule with two rows of optical fibers and with a gender of either male or female. When the fiber optic connectors have fiber optic connectors with the same gender, the plurality of optical fibers are inverted and when the fiber optic assemblies have fiber optic connectors with an opposite gender, the plurality of optical fibers are not inverted but switch rows. The inversion may also occur when the fiber optic connectors have the opposite gender in an alternative embodiment.

Abstract: An accessible cooling environment includes a back wall, an opening opposite the back wall, a roof panel, first and second side walls at least partially defining the opening, and an interior space at least partially defined by the back wall, roof panel, and first and second side wall. A fan configured to circulate air through the interior space, an evaporator disposed inside the interior space, and an air curtain assembly configured to form an air barrier adjacent to the opening. The air curtain assembly includes one or more deflectors for separating the air barrier into a first air curtain and a second air curtain. The first air curtain has a first temperature and the second air curtain has a temperature lower than the first temperature.

Abstract: Methods, apparatus, systems and articles of manufacture are disclosed. An apparatus for mounting a gas turbine engine to a pylon, the gas turbine including an upstream section and a downstream section, the gas turbine defining a roll axis, a yaw axis, and a pitch axis, the apparatus including: a first mount to couple the upstream section of the gas turbine engine to the pylon; a second mount to couple the upstream section of the gas turbine engine to the pylon, the second mount downstream of the first mount; a thrust linkage to couple the upstream section to the pylon, wherein the downstream section is decouplable from the upstream section without decoupling the first mount, the second mount, and the thrust linkage.

Abstract: Various embodiments of a jobsite keep out zone system are provided. The system includes one or more detectors configured to determine when an intruder is within and/or is approaching a protected area. In response to the determination, one or more alarms and/or notifications are generated.

Abstract: A method of exercising includes positioning a foot of a user onto a pedal of an exercise device. The pedal is pivotably connected to a pair of supports forming a triangular base and has a neutral position relative to a pivot axis of the device. The method includes applying a first force to the pedal to rotate the pedal about the pivot axis in a first direction, toward a first support. The method includes resisting movement of the pedal toward the first support with a resistance mechanism of the device. The method includes applying a second force to the pedal to rotate the pedal about the pivot axis in a second direction, opposite the first direction, toward a second support and away from the first support. The method includes resisting movement of the pedal toward the second support with the resistance mechanism of the device.

Abstract: A system for cooling a product includes an enclosed environment having an outlet, an inlet, and a temperature in a first temperature range. An antechamber is at least partially surrounding the inlet of the enclosed environment and has a temperature in a second temperature range. A conveyor system includes a conveyor path extending between the inlet and the outlet of the enclosed environment and provides a spiral travel path. The temperature range of the enclosed environment is configured to cool the product before the product exits through the outlet of the enclosed environment.

Abstract: A universal mounting system for a hard hat is provided that includes front and rear mounting locations and auxiliary ridges on either side. A visor is coupled to the hard hat mounting system in such a way as to provide access with minimal interference from the visor to the equipment attached to the mounting locations and ports in the auxiliary ridges. Various embodiments of visors enable modular designs that incorporate different materials and features of the visor. Parallel stretch zones enable folding and holding opposite brims of the visor. Enclosed elastic areas along the inner sides of visor provide user access to auxiliary ridges. Combinations of various accessories on hard hat and how the accessories work together on the universal mounting system are discussed: such as the interaction between visors, earmuffs, face shields, and lamps.
