International Classification:

H01L023/48

US Classification:

257746, 257741, 257734

Abstract:

One-dimensional nanostructures having uniform diameters of less than approximately 200 nm. These inventive nanostructures, which we refer to as “nanowires”, include single-crystalline homostructures as well as heterostructures of at least two single-crystalline materials having different chemical compositions. Because single-crystalline materials are used to form the heterostructure, the resultant heterostructure will be single-crystalline as well. The nanowire heterostructures are generally based on a semiconducting wire wherein the doping and composition are controlled in either the longitudinal or radial directions, or in both directions, to yield a wire that comprises different materials. Examples of resulting nanowire heterostructures include a longitudinal heterostructure nanowire (LOHN) and a coaxial heterostructure nanowire (COHN).

International Classification:

G02F 1/07

US Classification:

359260, 359245, 359238

Abstract:

A sub-wavelength grating structure that has a very broad reflection spectrum and very high reflectivity comprising segments made of high refractive index material disposed on a layer of low refractive index material and a low refractive index material disposed above and between the segments. The index differential between the high and low index materials determines the bandwidth and modulation depth. The larger difference in refractive indices gives rise to wider reflection bands. The reflection is sensitive to parameters such as the grating period, the grating thickness, the duty cycle of the grating, the refractive index and the thickness of the low index layer underneath the grating. The design is scalable for different wavelengths, and facilitates monolithic integration of optoelectronic devices at a wide range of wavelengths from visible to far infrared. The sub-wavelength grating reflectors may be used in a variety of settings such as tunable etalon filters and as a replacement for conventional distributed Bragg reflectors.

International Classification:

B65G 59/06

US Classification:

221257, 221256, 221263

Abstract:

An automated dispensing assembly includes a base, and a shuttle mounted in the base and movable under automated control between a loading position and a dispensing position. The shuttle includes a cavity configured to carry an object, such as cover. The depth of the cavity in the shuttle is approximately the same (or less) as the thickness of one of the objects. A storage module is mounted proximate the shuttle. The storage module is configured to store a plurality of objects and includes an opening exposing the next object to be dispensed. The cavity is positioned adjacent the opening in the storage module in the loading position and an edge of the cavity separates the object to be dispensed from the other objects in the storage module as the shuttle moves to the dispensing position.

US Classification:

73 32A, 73 5424

Abstract:

This invention provides methods and devices to measure physical characteristics of sample fluids. Samples are introduced into a sample chamber in contact with a mechanically oscillating working member. The vibrations are received by a piezoelectric sensor transducer and correlated to a sample characteristic, such as viscosity or density. The devices include a sample chamber in contact with one or more working members actuated by a piezoelectric actuator and/or monitored by a piezoelectric sensor.

Abstract:

This invention provides methods and devices for detecting the viscosity and conductivity of a conductive fluid sample. A sample fluid can be received into a sample chamber between a field inductor and sensor inductor. Electromagnetic fields generated by the field inductor can be modulated due to the counter-emf induced in the sample. The modulations can be detected by the sensor inductor and correlated to electric parameters in the fluid.
