A blanket comprising of a sheet of fabric of predetermined shape folded vertically, into three sections, and at the base of the folded fabric a gusset is attached. The folded fabric consists of a central area, a right-hand side and a left-hand side. Together, the central area, the right-hand side and the left-hand side make up the securing compartment. Attached to the front base of the folded fabric is a T-shaped wrapping flap with right and left securing flaps. The right-hand side and left-hand side of the folded fabric may include hook and loop fasteners for securing an infant inside the securing compartment. The right and left securing flaps of the T-shaped wrapping flap include hook and loop fasteners that wrap around the sides and the back of the securing compartment and overlap and join in the back of the securing compartment, and thus, the back of the infant. T-shaped wrapping flap may be eliminated and replaced with two additional flaps; a right alternative flap and a left alternative flap. The alternative flaps may have many shapes and sizes, ranging from wide and oval, to narrow and rectangular. The alternative flaps overlap and join in the front of the securing compartment, and thus, in front of the infant.

Flap side edge noise mechanisms have been addressed in a large number of studies during the last decades. A specific vortex system emanates from the flap side edge due to the static pressure difference between the upper and lower flap surfaces. Such pressure difference leads to a merging between the two vortex systems that are generated on the upper and lower edges of the flap side contour. The present invention intends to show the application of a perforated blade seal (21) at the lower (11) and / or upper (8) side edges of the control surface contour, such as a flap (3), with the purpose of acting as a vortex generator, making difficult for the lower vortex system to move upwards and merge with the upper vortex system. The perforated blade seals (21) are preferably arranged on the inboard and outboard edges of high lift flaps (3).

A running shoe design focused on the heel section of running shoes used in, for example, T2 transition phase of the sport of triathlon. A heel counter portion of the shoe is a retractable flap. The flap retracts to an open position at a 45 to 90 degree angle awaiting the unhindered insertion of the runner's foot without any need for the runner to bend or sit. Immediately after the foot is inserted, the flap is closed with a pressing forward action by the athlete's other foot. The flap and the sides of the shoe are coated with adhesive, velcro-like materials. A variation of the foregoing uses a heel counter cut from the center top to the midsole area at the bottom, resulting in an acceptable size opening for uninhibited foot insertion when the flap (or strap) portion of the heel counter is set in the open position.

Exhalation and inhalation valves that are sized and adapted to fit on a mask body of a personal respiratory protection device. The exhalation and inhalation valves comprise a valve seat that has a seal surface and an orifice through which an exhale flow stream may pass to leave the interior gas space. A flexible flap is mounted to the valve seat such that the flap makes contact with the seal surface when the valve is in its closed position and such that the flap can flex away from the seal surface during an exhalation to allow exhaled air to pass through the orifice to ultimately enter an exterior gas space. The flexible flap has at least first and second juxtaposed layers where at least one of the layers is stiffer or has a different elastic modulus than the other layer. These valves provide extraordinarily lower pressure drop in use, and they operate more efficiently and require less actuation power to operate. The end user therefore derives greater comfort when wearing a respiratory mask that uses the inventive valve.

Releasable fasteners are provided for fastening the rear lower portions to the upper portion of the shirt, thereby providing access to the spine.

Prolonged and severe tissue hypoxia results in tissue necrosis in pedicled flaps. We demonstrate the potential of near-infrared spectroscopy for predicting viability of compromised tissue portions. This approach clearly identifies tissue regions with low oxygen supply, and also the severity of this challenge, in a rapid and non-invasive manner, with a high degree of reproducibility. Early, nonsubjective detection of poor tissue oxygenation following surgery increases the likelihood that intervention aimed at saving the tissue will be successful.

A method and system for customizing a flap created from a transparent material compensates for aberrations, particularly higher order aberrations, which are pre-existing or otherwise induced during creation of the flap. Before flap creation, the distorted wavefront of the transparent material is determined and the topology of the transparent material is defined in order to predict contributions likely to be encountered or induced by the stress distribution during creation of the flap. In view of the topology of the transparent material, a prototypic dissection path based on the distorted wavefront is refined to establish a refined dissection path. As a result, the flap is created along the refined dissection path to correct and minimize or eliminate the formation of higher order aberrations.
