Methods and apparatus for screening diverse arrays of materials are provided. In one aspect, systems and methods are provided for imaging a library of materials using ultrasonic imaging techniques. The system includes one or more devices for exciting an element of the library such that acoustic waves are propagated through, and from, the element. The acoustic waves propagated from the element are detected and processed to yield a visual image of the library element. The acoustic wave data can also be processed to obtain information about the elastic properties of the library element. In another aspect, systems and methods are provided for generating acoustic waves in a tank filled with a coupling liquid. The library of materials is then placed in the tank and the surface of the coupling liquid is scanned with a laser beam. The structure of the liquid surface disturbed by the acoustic wave is recorded, the recorded disturbance being representative of the physical structure of the library. In another aspect of the invention, a mechanical resonator is used to evaluate various properties (e.g., molecular weight, viscosity, specific weight, elasticity, dielectric constant, conductivity, etc.) of the individual liquid elements of a library of materials. The resonator is designed to ineffectively excite acoustic waves. The frequency response of the resonator is measured for the liquid element under test, preferably as a function of time. By calibrating the resonator to a set of standard liquids with known properties, the properties of the unknown liquid can be determined. An array of library elements can be characterized by a single scanning transducer or by using an array of transducers corresponding to the array of library elements. Alternatively, multiple resonators of differing design may be used to evaluate each element of a library of elements, thus providing improved dynamic range and sensitivity.

Bone tissue at the interface of a bone implant is shielded from stresses found in normal bone because of the higher stiffness or rigidity in the implant versus in bone. The resulting “stress shielding” of the bone by the implant eventually results in resorption of bone at the bone-implant interface and ultimately necessitates replacement of the bone implant. To overcome these problems, an implantable biomimetic prosthetic bone having a porous surface, a fiber-reinforced composite structure, and a polymer-based core is disclosed. The prosthetic bone is a good match for structure, stiffness, viscoelastic properties, specific weight and overall structure as real bone or host tissues adjacent to the prosthetic bone. The prosthetic bone may be formed as a total hip prosthesis.

Since concrete materials do not cure quick enough when prototyping methods are used, so that a lower layer (2a) is already completely cured when the next layer (2b) is applied, a support material (4) is applied about the formed element (100) that is being built up in order to compensate for the lack of pressure resistance of the lower layer (2a), wherein the support material preferably has the same specific weight as the material (3) of the formed element (100). Thus, 3D-printing as well as selective curing are facilitated as build up methods.

A display component implements a text entry system for a device, such as a cell phone or other handheld device, has various layers that mimic characteristics of a conventional keyboard. A keyboard is displayed on a dynamic touch screen display. When a key is pressed by a user, the surface area of the key on the display depresses, thereby mimicking a conventional keyboard that would typically be used with a desktop or laptop computer. The display component is comprised of various layers or panels. One layer is a compressible touch sensitive or touch screen layer. Adjacent to this layer is a compressible display layer. Another layer is a deformable or cushion layer for supporting a specific weight, such as the weight of user fingers or hands. Adjacent to the deformable layer is a lower touch sensitive layer which has a coordinate system. A user pressing down on a key on the compressible display component at a specific spot creates a downward deformation at that specific spot, thereby providing a more ergonomic feel to the user when entering text into the device.

Modified mineral fillers, derived from either a coarse particle kaolin clay or a coarse particle ATH, having excellent utility in thermoset polymers as low paste viscosity fillers are disclosed. The method of treatment involves the use of specific weight ratio combinations of a silane and a long chain aliphatic alcohol. The treatment of clay can also involve the auxiliary use of a surfactant in small amounts, which is utilized to emulsify the silane and aliphatic alcohol treatment components in water either individually or as a co-emulsion blend prior to their addition to the clay. The surfactant, which is preferably a nonionic surfactant having a HLB value of 12-18, aides in uniformly treating all the clay particle surfaces with the silane / alcohol treatment combination. Coarse particle clays having general utility in the invention are those having an average Stokes equivalent particle diameter of at least 3.0 microns, while the coarse particle ATH fillers having general utility in the invention are those having a BET surface area value less than 5.0 m2 / g.
