Abstract: An electronic athletic training system includes a first detection device and a second detection device, each of which includes a transmitter, a receiver, one or more visual indicators, a processor, and a computer-readable storage medium. A transmitter of one detection device emits a light beam to the receiver of the other detection device when the transmitter is in proximity to the receiver. A detection device performs one or more actions in response to detecting that the light beam has been broken.

Abstract: A hybrid fitness ladder including at plurality of rung units, along with a rung unit for such a ladder, are described. Each one rung unit includes a plurality of elevated rails as well as a plurality of ground rails, wherein each ground rail is integrated or connected to at least one elevated rail. The hybrid fitness ladder may further include at least one rung unit connector configured to removably attach one rung unit to another rung unit in positions where the elevated rails are positioned as ladder rungs, in positions where the ground rails are positioned as ladder rungs, or a combination of the two. The elevated rails and ground rails may be made of a semi-flexible material that is deformable and biased toward a first configuration.

Abstract: A ported shroud for a compressor associated with a gas turbine engine includes a primary inlet configured to be in fluid communication with the compressor, and the primary inlet is defined to extend along a central axis of the ported shroud. The ported shroud includes a bellmouth that surrounds the primary inlet, and a port plenum configured to be in fluid communication with the compressor. The port plenum extends along an axis that is transverse to the central axis of the ported shroud and transverse to a direction of fluid flow. The port plenum has a port plenum inlet defined about the axis, and the port plenum inlet is defined through the bellmouth such that a tortuous path is defined to the port plenum inlet. The port plenum including a port plenum outlet downstream from the port plenum inlet configured to be in fluid communication with the compressor.
