A medical monitoring system, such as an oximetry system, applies an attachment for securing an optical probe to a measurement site. The attachment has an elongated support with a first end and a second end, and a dedicated area in proximity of the first end. The dedicated area receives an optical probe and includes a material that is transparent for light emitted and received by the optical probe. The dedicated area mountably receives the optical probe on the material so that in use, the material is positioned between the optical probe and a surface of a measurement site. The optical probe may be factory-mounted to the dedicated area of the attachment as a ready-to-use sensor. In the alternative, the attachment may be available as an individual component, or as a part of a kit including the attachment and the optical probe.

The invention relates generally to a probe interface method and apparatus for use in conjunction with an optical based noninvasive analyzer. More particularly, an algorithm controls a sample probe position and attitude relative to a skin sample site before and / or during sampling. For example, a sample probe head of a sample module is controlled by an algorithm along the normal-to-skin-axis. Preferably, the sample probe head is positioned in terms of 3-D location in the x-, y-, and z-axes and is attitude orientated in terms of pitch, yaw, and roll. Further, attitude of the probe head is preferably orientated prior to contact of the sample probe head with the tissue sample using indicators, such as non-contact distance feedback from capacitance sensor, contacting or non-contacting optical sensors, and / or contact electrical sensors.

A touchframe system includes a plurality of light emitting elements and a plurality of light receiving elements positioned around the perimeter of the display area. Each of the light receiving elements in combination with a plurality of the light emitting elements form a zone of light beam paths. The number and positioning of receivers is sufficient to form a plurality of partially overlapping zone pairs. These zone pairs are arranged relative to the display area such that any touch event lies within at least two zone pairs. A processor monitors each of the zone pairs for blockage of at least one light beam path. Upon such blockage, the processor calculates the location of the touch event associated with the blockage based on the slopes and end points of at least two intersecting blocked light beam paths from a first zone pair and two intersecting blocked light beam paths from a second zone pair.

Optical proximity correction (OPC) and assist feature rules are generated using a process window (PW) analysis. A reference pitch is chosen and the mask bias is found that optimizes the process window. This can be done using standard process window analysis or through a weighted process window (WPW) analysis which accounts for focus and dose distributions that are expected in a real process. The WPW analysis gives not only the optimum mask bias, but also the center focus and dose conditions for the optimum process centering. A series of other pitches and mask biases are then analyzed by finding the common process window with the reference pitch. For the standard PW analysis, a common process window is found. For the WPW analysis, the WPW is computed at the center focus and dose conditions found for the reference pitch. If mask or lens errors are to be accounted for, then multiple structures can be included in the analysis. Once the common process windows for the mask features of interest have been computed, functional fits to the data can be found. Once the functional forms have been found for each of the OPC parameters, the rules table can be determined by solving for the spacings of interest in the design.

An optical coupler for coupling light from at least two input fibers into one output fiber and a method of fabricating and use of an optical coupler. The coupler comprises a) an input section comprising an output end face at one end of the bundling-length of input fibers; and b) an output section comprising an output fiber comprising a confining region for confining light propagated in the input fibers and a surrounding cladding region and having an input end face; wherein the output end face of said input section is optically coupled to the input end face of the output section and at least the confining region of the output fiber is tapered down from a first cross sectional area at the input end face to a second, smaller cross sectional area over a tapering-length of the output fiber.

Method for obtaining information about objects in an environment around a vehicle in which infrared light is emitted into a portion of the environment and received and the distance between the vehicle and objects from which the infrared light is reflected is measured. An identification of each object from which light is reflected is determined and a three-dimensional representation of the portion of the environment is created based on the measured distance and the determined identification of the object. Icons representative of the objects and their position relative to the vehicle are displayed on a display visible to the driver based on the three-dimensional representation. Additionally or alternatively to the display of icons, a vehicular system can be controlled or adjusted based on the relative position and optionally velocity of the vehicle and objects in the environment around the vehicle to avoid collisions.

This invention provides an apparatus and method for injecting gas within a plasma reactor and tailoring the distribution of an active species generated by the remote plasma source over the substrate or wafer. The distribution may be made more or less uniform, wafer-edge concentrated, or wafer-center concentrated. A contoured plate or profiler is provided for modifying the distribution. The profiler is an axially symmetric plate, having a narrow top end and a wider bottom end, shaped to redistribute the gas flow incident upon it. The profiler is situated below an input port within the plasma reactor chamber and above the wafer. The method for tailoring the distribution of the active species over the substrate includes predetermining the profiler diameter and adjusting the profiler height over the substrate. A coaxial injector tube, for the concurrent injection of activated and non-activated gas species, allows gases (or gas mixtures) to be delivered in an axially symmetric manner whereby one gas can be excited in a high density RF plasma, while the other gas can be prevented from excitation and / or dissociation caused by exposure to the plasma or heated surfaces in the source apparatus. The gas admixture that is not to be excited or dissociated prior to contact with the wafer surface is shielded from direct exposure to the RF field surrounding the plasma confinement tube. The tube walls are also shielded from the infrared energy emitted from the plasma. The profiler is used in conjunction with the coaxial injector tube for redistributing the excited gases emerging from the injector tube, while allowing the non-excited gases to pass through its center.
