A protective case for handheld devices with improved protection characteristics, durability, convenience of use, and functionalities without compromising aesthetics. The protective case includes a “glove” or “skin” piece of a softer material that substantially covers and grips the entire back of the electronic device, by wrapping over the edge of the electronic device (without obscuring the display / touch screen on the front of the device). One or more separate complementary frame pieces, braces and the like made of a hard material are attached over the glove piece, extending over a substantial area of the glove piece, thereby creating a robust interlocking hybrid structure. Openings are provided in the protective case to allow for user interaction with the device, including access to the interfaces (e.g., screens, buttons, sockets, etc.) provided on the device.

A method for forming a platen useful for forming nanoscale wires for device applications comprises: (a) providing a substrate having a major surface; (b) forming a plurality of alternating layers of two dissimilar materials on the substrate to form a stack having a major surface parallel to that of the substrate; (c) cleaving the stack normal to its major surface to expose the plurality of alternating layers; and (d) etching the exposed plurality of alternating layers to a chosen depth using an etchant that etches one material at a different rate than the other material to thereby provide the surface with extensive strips of indentations and form the platen useful for molding masters for nano-imprinting technology. The pattern of the platen is then imprinted into a substrate comprising a softer material to form a negative of the pattern, which is then used in further processing to form nanowires. The nanoscale platen thus comprises a plurality of alternating layers of the two dissimilar materials, with the layers of one material etched relative the layers of the other material to form indentations of the one material. The platen is then oriented such that the indentations are parallel to a surface to be imprinted.

A powered, gyroscopically balanced unicycle device to be used while standing, having leg contact surfaces which are made of a yielding, slightly soft material whose mild friction against the user's legs allows stable, precise control of the device without restraining the legs in any way.

Various structures are provided for supporting the wheel and keeping it in place as it spins; absorbing small vertical movements of the wheel to prevent them from being transmitted to the foot platforms; enabling folding of the foot platforms; and facilitating carrying of the device by hand. Other embodiments are described and shown.

A multiple lumen catheter having a soft, tapered multiple lumen distal tip for insertion into a body vessel. One of the lumens is sized to pass over a guidewire such that the catheter can be inserted into the body vessel using the Seldinger technique. At least one medical implement lumen is used for placement or positioning of a biomedical sensor or other medical implement. For example, at least one optical fiber passing through the medical implement lumen may transmit and receive light at the distal tip for measuring oxygen saturation of the blood. The catheter may have a cylindrical catheter body to which the soft distal tip attaches. The soft tip reduces the possibility of vessel or tissue puncture and abrasion. The tip is constructed of a soft plastic or pliable material that yields easily when force is applied. For example, the tip may be made of a softer material than the catheter body, or if made of the same material, the tip can be configured with thinner walls or a higher air-to-material ratio cross-section. Various geometrical configurations and combinations of materials can be used to decrease the flexible resistance of the tip to an applied load. One particular useful application for the catheter of the present invention is as a central venous catheter equipped with fibers for measuring oximetry. The fibers extend to the distal end of the tip and are preferably secured therein with minimal adhesive so as to limit the stiffness added to the tip. One particular useful construction is to secure the fibers within the medical implement lumen using adhesive only along a length of between about 0.5–3.5 mm.

Interconnection elements for electronic components, exhibiting desirable mechanical characteristic (such as resiliency, for making pressure contacts) are formed by using a shaping tool (512) to shape an elongate core element (502) of a soft material (such as gold or soft copper wire) to have a springable shape (including cantilever beam, S-shape, U-shape), and overcoating the shaped core element with a hard material (such as nickel and its alloys), to impart to desired spring (resilient) characteristic to the resulting composite interconnection element. A final overcoat of a material having superior electrical qualities (e.g., electrical conductivity and / or solderability) may be applied to the composite interconnection element. The resulting interconnection elements may be mounted to a variety of electronic components, including directly to semiconductor dies and wafers (in which case the overcoat material anchors the composite interconnection element to a terminal (or the like) on the electronic component), may be mounted to support substrates for use as interposers and may be mounted to substrates for use as probe cards or probe card inserts. The shaping tool may be an anvil (622) and a die (624), and may nick or sever successive shaped portions of the elongate elements, and the elongate element may be of an inherently hard (springy) material. Methods of fabricating interconnection elements on sacrificial substrates are described. Methods of fabricating tip structures (258) and contact tips at the end of interconnection elements are also described.

A mattress has a main sleep area surrounded by a perimeter trim. Both the main sleep area and the perimeter trim are formed from wire springs contained within pockets of soft material. The wire springs in the sleep area are arranged in honeycomb nested rows. The wire springs of the perimeter trim, which are of different wire construction with different flex characteristic from the wire springs in the main sleep area, are arranged in side by side rows which are not honeycomb nested. In addition, the wire springs of the perimeter trim are pivotally linked directly to one another across the perimeter trim, both widthwise and lengthwise of the mattress which produces an essentially non-feelable flex transition between the perimeter trim and the main sleep area of the mattress.
