Nanocrystal doped matrixes

The present invention provides matrixes doped with semiconductor nanocrystals. In certain embodiments, the semiconductor nanocrystals have a size and composition such that they absorb or emit light at particular wavelengths. The nanocrystals can comprise ligands that allow for mixing with various matrix materials, including polymers, such that a minimal portion of light is scattered by the matrixes. The matrixes of the present invention can also be utilized in refractive index matching applications. In other embodiments, semiconductor nanocrystals are embedded within matrixes to form a nanocrystal density gradient, thereby creating an effective refractive index gradient. The matrixes of the present invention can also be used as filters and antireflective coatings on optical devices and as down-converting layers. The present invention also provides processes for producing matrixes comprising semiconductor nanocrystals.

Electrically tunable diffractive grating element

The invention relates to an optical device (50) for manipulating a light wave (λ) using a diffractive grating structure (G). According to the basic idea behind the invention a prior art type diffractive grating structure having a permanently shaped surface relief is substituted with an electrically deformable diffractive grating structure (G), where a preformed, basic surface relief of the grating is composed of dielectric and deformable viscoelastic material, which can be electrically and sequentially fine tuned in shape to adjust the diffraction properties of said grating individually for different wavelengths. The invention permits manufacture of virtual display devices with a significantly larger exit pupil diameter than prior art solutions without degrading the color uniformity of the display device.

Catheters having selectively insertable or selectively activatable and releasable stiffening mechanisms are provided. In general, the catheter is inserted, navigated and withdrawn from a subject in a relaxed, flexible condition and stiffening mechanisms are deployed to prevent the catheter from shifting during placement or operation of an accessory device or tool through the catheter. Stiffening members(s) may be inserted into and removed from one or more longitudinal channel(s) provided in proximity to the catheter wall and generally coaxial with the primary catheter lumen to change the stiffness properties of the catheter. The properties, configuration and size of the stiffening members and channels may be varied to vary the stiffness properties of the catheter and stiffening members may be constructed from materials having shape change properties or materials that change conformation or stiffness with application of heat, current or electrical field. Stiffening mechanisms may also employ energy absorbing and viscoelastic polymer materials having variable stiffness properties depending on ambient conditions.

Combat shirt and armor system

A protective body armor system for protection against ballistic threats has an armored element such as a vest with front and rear ballistic armor. A long-sleeved shirt is worn beneath the ballistic armor which has a wicking, lightweight, low thermal insulation torso element. Two long sleeves are connected to and extend from the torso element. The torso element is substantially overlain by portions of the armor element, while portions of the sleeve extend beyond the armored element. The shirt has a durable collar connected to the torso element and to the two sleeves. The collar extends upwardly from the armored element. The collar is less resilient than the torso element, and serves to connect the two sleeves and to restrain the garment from undesired distortion.

Closed cell foams including poly-4-hydroxybutyrate and copolymers thereof

Methods to produce substantially closed cell foams with densities less than 0.75 g / cm3, and more preferably less than 0.5 g / cm3, without substantial loss of the polymer's weight average molecular weight, have been developed. The closed cells foams have an open cell content of generally less than 50%, and more preferably an open cell content of less than 20%, and the cells have a maximum diameter of less than 5 mm. The foam may include poly-4-hydroxybutyrate or a copolymer thereof. Preferably, the foam is derived by heating a foam polymer formula to a temperature above the melt temperature of the polymer to form a melt polymer system, adding a blowing agent to produce a foamable melt, extruding the foamable melt through a die to a lower pressure to cause foaming, cooling of the foam, and solidification of the foam. These foam structures can be used for fabrication of medical products.
