A method of uniformly dispersing a nano powder throughout a micron powder. Ordinary mixing or agitation does not succeed in attaining uniform dispersal: the nano powder agglomerates into microscopic masses. In one form of the invention, a charge of a micron powder, with fifty weight percent of charge of nanopowder is loaded into a ball mill. The mixture is ball milled for less than two hours, at room temperature in a dry condition, and produces a highly uniform distribution of the nano powder throughout the micron powder.

A GaN-based semiconductor light-emitting device includes (A) a first GaN-based compound semiconductor layer 13 having n-type conductivity, (B) an active layer 15 having a multi-quantum well structure including well layers and barrier layers for separating between the well layers, and (C) a second GaN-based compound semiconductor layer 17 having p-type conductivity. The well layers are disposed in the active layer 15 so as to satisfy the relation d₁<d₂ wherein d₁ is the well layer density on the first GaN-based compound semiconductor layer side in the active layer and d₂ is the well layer density on the second GaN-based compound semiconductor layer side.

Embodiments of the invention provide analyte sensors having optimized electrodes and/or configurations of electrode elements as well as methods for making and using such sensors. Typical embodiments of the invention include glucose sensors used in the management of diabetes.

A transtibial patellar tendon bearing (PTB) prosthesis for below the knee amputees is disclosed. The prosthesis includes a socket, and a foot prosthesis attached to a modular shank component using a foot rotator device. Using the rotator device, the foot component of the prosthesis may be smoothly and axially rotated internally or externally ±150° with respect to the shank component about the axis of the shank component. The wide range of axial rotation enables a more even load distribution on the whole lower limb of an amputee and enables an amputee to comfortably assume a wide range of biomechanical positions, such as sitting or kneeling. A recoil spring, having a selectable tension, is positioned within the rotatable component and selectively limits and retains the relative rotation of the upper portion and the lower portions. A locking mechanism selectively prevents rotation when the foot component is engaged.

A freestanding battery separator includes a microporous polymer web with passageways that provide overall fluid permeability. The polymer web preferably contains UHMWPE and a gel-forming polymer material. The structure of or the pattern formed by the gel-forming polymer material and wettability of the UHMWPE polymer web result in a reduction of the time required to achieve uniform electrolyte distribution throughout the lithium-ion battery. In a first embodiment, the gel-forming polymer material is a coating on the UHMWPE web surface. In a second embodiment, the gel-forming polymer material is incorporated into the UHMWPE web while retaining overall fluid permeability. Both embodiments produce hybrid gel electrolyte systems in which gel and liquid electrolyte co-exist.

A head-box for depositing slurry upon a moving web including a main metering roll, a companion roll disposed in closely spaced relation to the metering roll and a vibrating gate which forms a nip between the metering roller and the gate. The nip is arranged to retain a supply of the slurry, and the rolls are driven so slurry retained in the nip progresses over an upper outer peripheral surface of the metering roll to be deposited upon the web. Also, preferably included is a doctor blade disposed in operational relationship to the metering roll for directing the slurry downwardly from the outer metering roll surface to a point above the surface of a carrier for a fiberglass layer upon which the slurry layer is deposited. The vibrating gate and doctor blade may be pivotally mounted to either side of the surfaces of the head-box.

Wafer carrier arranged to hold a plurality wafers and to inject a fill gas into gaps between the wafers and the wafer carrier for enhanced heat transfer and to promote uniform temperature of the wafers. The apparatus is arranged to vary the composition, flow rate, or both of the fill gas so as to counteract undesired patterns of temperature non-uniformity of the wafers. In various embodiments, the wafer carrier utilizes at least one plenum structure contained within the wafer carrier to source a plurality of weep holes for passing a fill gas into the wafer retention pockets of the wafer carrier. The plenum(s) promote the uniformity of the flow, thus providing efficient heat transfer and enhanced uniformity of wafer temperatures.

A system and method for testing for the presence of antigens in food stuffs permits a user to test food products for the presence of antigens for a given food allergy that the user may have. The system comprises two main components, a base station and a test well. The user places a sample of food into the test well. A macerator homogenizes the food in the test well. Antibodies to a particular antigen are bound to an antigen detector in the test well. The base station includes a cartridge dock which powers the macerator and the antigen detector. Antigen-antibody binding provides a change detectable by the detector, which signals the base station of the presence of a threshold degree of antigen-antibody binding and alerts the user of the presence of the antigen, such as by a visual or audible indicator.
