A supporting structure for concurrently holding a plurality of cylindrical containers for substances for medical, pharmaceutical or cosmetic applications is provided. The supporting structure includes a supporting base having a plurality of receptacles, which are configured such that the containers can be inserted into the associated receptacles, wherein the receptacles extend in the longitudinal direction of the containers and are configured to hold side wall portions of the containers at least partially clamped. The receptacles are continuous side walls, wherein the opening widths of the receptacles can be adjusted by a coordinated adjustment of the side walls of the receptacles between a first position, in which the containers can be inserted into the receptacles, and a second position in which the containers are clamped. The bottoms or upper ends of the containers are exactly fixed at a given height despite tolerances.

An overhead microphone assembly using multiple unidirectional microphone elements. The microphone assembly is installed overhead, generally above all the desired sound sources and below the undesired sound sources. The signals from these multiple microphone elements are fed into a microphone steering processor which can mix and gate the signals to ensure the best signal / noise ratio. The steering processor may also track the sound source dynamically when such tracking (source locating) is desired. The resulting audio signal from the steering processor may be further processed, such as echo canceling, noise reduction and automatic gain control.

A method for making a device includes providing a tubular member which will be formed into the device, masking at least a portion of the inner surface of the tubular member with a removable sacrificial material, selectively removing a portion of the tubular member and sacrificial material using a laser device, and mechanically removing the sacrificial material from the inner surface of the tubular member. Ultrasonic energy could be applied to a workpiece which is being laser cut to prevent any generated slag from welding itself to an exposed surface of the workpiece. A compressed fluid or gas, such as air, could be used to clean the surface of the laser-cut workpiece to remove slag formation which adheres to the surface of the cut workpiece.

A piezooscillator having a piezoelectric vibrator and an oscillation circuit in a space surrounded by a substrate and a cover, which has a smaller size and height, and further, which can be assembled easily and suppress power consumption, is provided. The piezooscillator includes a recessed portion formed on the surface of the substrate; a supporting member supporting the piezoelectric vibrator while the piezoelectric vibrator is in a state partially or entirely accommodated in the recessed portion and floating from the substrate; a heating element provided on the surface of the piezoelectric vibrator; a temperature sensitive element provided in the space; and a temperature control unit provided in the space and controlling power supply to said heating element based on an output of the temperature sensitive element, in which, it is possible to reduce capacity of the space accommodating the piezoelectric vibrator and the heating element by eliminating the need of an additional substrate provided above the substrate as in conventional piezoelectric vibrators, so that the size and height of the piezooscillator can be reduced, in which assembling is eased, and power consumption can be reduced on the back of suppressed heat release to the substrate.

The present invention provides a detection article including at least one fluid control film layer having at least one microstructured major surface with a plurality of microchannels therein. The microchannels are configured for uninterrupted fluid flow of a fluid sample throughout the article. The film layer includes an acquisition zone for drawing the fluid sample into the plurality of microchannels at least by spontaneous fluid transport. The film layer also includes a detection zone having at least one detection element that facilitates detection of a characteristic of the fluid sample within at least one microchannel of the detection zone. The detection article may be formed from a plurality of film layers that are stacked to form a three-dimensional article.

This invention relates to an implant for a musculoskeletal defect having a bioactive agent having a concentration gradient.

Improved autofocusing (“AF”) methods and devices for lithography are provided. Some embodiments of the invention provide an AF system that includes one or more interferometers for measuring a distance to a wafer surface or a reticle surface. The invention includes methods and devices for calibrating the interferometer(s) according to known distances to a target. According to some embodiments of the invention, a spatial filter reduces the amount of undesired signal coming from the wafer or reticle surface. In some such embodiments, higher orders of diffracted light from the wafer or reticle multilayer surfaces are eliminated with a pinhole filter oriented to reject light that is not vertically directed. Other embodiments include a spatial filtering system that passes a selected diffraction order, e.g., the first order of diffracted light, from the target.

An etchant for removing materials with a plurality of selectivities exhibits a first etch selectivity at a first temperature and a second etch selectivity at a second temperature. The etchant may include phosphoric acid, fluoboric acid, or sulfuric acid. The materials that the etchant is configured to remove may include dielectric materials, such as silicon nitride and silicon oxide. The first temperature may be about 175° C. and the second temperature may be about 155° C.
