A system for creating a reticle data file from an IC layout data file can include a processing module and a graphical display. The processing module can read the IC layout data file, identify critical features and define a halo region around each of the critical features. The graphical user interface can facilitate user input and control. The system can be coupled to a remote IC layout database through a LAN or a WAN.

In a self-operated karaoke recording booth a user is provided with a selection of background scenes from which to choose and also with the option of having the lyrics of the karaoke selection displayed or suppressed. A video camera positioned at the user's eye level is located on the nonreflective side of a one-way mirror and is directed at a specified performer location through the one-way mirror, which is inclined at a forty-five degree angle relative thereto. Messages and video displays are provided to the user by a video display monitor connected to a computer that faces the reflective side of the one-way mirror and is also located at a forty-five degree angle relative thereto. The system is designed to maintain the visual focus of the performer directly into the lens of the video camera throughout the performance and to combine the video camera images with the background scene in such a way as to avoid a double exposure or phantom image of the performer against the background. The performer can choose to have the lyrics of the selected karaoke composition displayed or suppressed. If the election is for a display, the lyrics are displayed at the center of the viewing screen, directly in line with the video camera.

Miniaturized, five and six degrees-of-freedom magnetic sensors, responsive to pulsed DC magnetic fields waveforms generated by multiple transmitter options, provide an improved and cost-effective means of guiding medical instruments to targets inside the human body. The end result is achieved by integrating DC tracking, 3D reconstructions of pre-acquired patient scans and imaging software into a system enabling a physician to internally guide an instrument with real-time 3D vision for diagnostic and interventional purposes. The integration allows physicians to navigate within the human body by following 3D sensor tip locations superimposed on anatomical images reconstructed into 3D volumetric computer models. Sensor data can also be integrated with real-time imaging modalities, such as endoscopes, for intrabody navigation of instruments with instantaneous feedback through critical anatomy to locate and remove tissue. To meet stringent medical requirements, the system generates and senses pulsed DC magnetic fields embodied in an assemblage of miniaturized, disposable and reposable sensors functional with both dipole and co-planar transmitters.

A method for reducing power consumption includes the steps of: a) receiving control signals from a number of functional blocks; b) selectively deactivating a particular functional block upon a request from that functional block or from another functional block; and c) activating the particular functional block upon a request from another functional block.

The invention is a method for operating a file server system in a cluster mode that provides for relatively rapid and reliable takeover of a failed file server in the cluster by a partner file server when the failed file server has detected a fault that will cause it to shut down. This is done by the failed file server requesting the one file server to take over its file services after detecting the fault in its operations, the one file server letting the failed file server complete existing file service requests from clients, refusing further file service requests addressed to the failed file server, and the one file server taking over by transferring file service requests to the one file server. As part of this takeover the one file server takes on the identity of the failed filer and activates network interfaces and network addresses that replicate the failed server's network addresses.

Blends of at least two polymers incorporating propylene-derived units and processes for producing such blends are provided. The first polymer of the blend is a low crystallinity polymer including propylene-derived units. The second polymer is a high crystallinity polymer including propylene-derived units. The polymer blends exhibit the beneficial performance characteristics of low crystallinity propylene polymers while minimizing certain processing and handling problems associated with low crystallinity propylene polymers. Low crystallinity propylene polymer pellets often exhibit a tendency to agglomerate because of the softness of such particles. Agglomeration of the pellets creates problems in handling and processing the particles. The polymer blends disclosed reduce the tendency of polymer pellets to agglomerate while maintaining the desirable physical properties, such as elastomeric properties, exhibited by low crystallinity propylene polymers. Various processes for producing the polymer blends are also provided.

A single-piece top surface display and integrated front cover for an electronic device. In one embodiment, the cover comprises a thin, flexible, transparent layer coupled with a supporting structure. The flexible layer is supported above a display screen which is coupled with pressure activated sensors located under the display screen. The cover is dust-free, waterproof, and has a flat outer surface that is free of any steps or indentations. Users input data by applying pressure on the cover which causes the display screen to deflect and activate the sensors. The pressure exerted on the sensors is triangulated to register the position of the user input. In another embodiment, the cover is transparent, rigid, and directly contacts the pressure activated sensors which are located in front of the display screen or in the housing behind it. When pressure is applied to the cover, the cover deflects and activates the sensors. In both embodiments, an accelerometer identifies valid input events.

Obtaining spectral images of an eye includes taking an optical system that images eye tissue onto a digital sensor array and optically fitting a multi-spectral filter array and the digital sensor array, wherein the multi-spectral filter array is disposed between the digital sensor array and an optics portion of the optical system. The resulting system facilitates acquisition of a snap-shot image of the eye tissue with the digital sensor array. The snap shot images support estimation of blood oxygen saturation in a retinal tissue. The resulting system can be based on a non-mydriatic fundus camera designed to obtain the retinal images without administration of pupil dilation drops.

A dispensing cartridge for a relatively precise dispensing of various fluids having a relatively wide range of viscosities is disclosed. The dispensing cartridge in accordance with the present invention is relatively simpler in configuration than known dispensing cartridges while minimizing leakage of the fluid and eliminating problems associated with chemical attack of the O-ring by the fluid in the dispensing cylinder. In particular, the dispensing cartridge in accordance with the present invention includes a cylinder; a piston with a central bore and a bleed plug. In order to simplify the design, the air vent is configured as a tortuous path, for example, a spiral path, defined by a spiral bleed plug, which in a pre-staged position, allows air to freely escape along the spiral path along the circumference of the plug. As the piston contacts the fluid, the forward motion of piston is resisted by the high back pressure created by the small effective diameter and relatively long length of the spiral path. Once the piston contacts the fluid, the spiral plug is pushed into the piston closing the spiral path. By controlling the fluid flow by way of a tortuous path, the amount of fluid backflow through the piston is minimized if not eliminated, thus eliminating the need for an annular overflow chamber, thereby simplifying the design of the piston. In order to minimize problems related to the sealing of the piston within the dispensing cartridge, the piston may be provided with one or more radially extending sealing lips. These sealing lips are used in lieu of or in conjunction with an O-ring. The sealing lips further simplify the design by eliminating the O-ring as well as the need for an annular chamber adjacent thereto as well as problems relating to chemical attack of the O-ring by the fluid within the dispensing cylinder. In an alternative embodiment for use that is particularly adapted with non-aggressive fluids, the piston is provided with a single sealing lip and an O-ring.

The present invention relates to diagnostic assays whereby the detection means is based on electrochemical reactions. This means that the label to be detected provides an electric signal. Preferred labels are enzymes giving such a signal. Provided is a flow cell whereby a solid phase is provided in a flow stream of the sample, in close proximity to a working electrode to detect any electrical signal. In a typical embodiment, a sample is mixed with molecule having specific binding affinity for an analyte of which the presence in the sample is to be detected, whereby said specific binding molecule is provided with a label. The conjugate of labelled specific binding molecule and analyte is then immobilized on the solid phase in the vicinity of the working electrode, the flow cell is rinsed with a solution and afterwards a substrate solution for the label (an enzyme) is provided upon which an electrical signal is generated and can be detected by the working electrode. The methods and devices of the present invention are particular useful for liquids which comprise many substances that may disturb measurement in conventional assays. The design of the flow cell allows for removal of said interfering substances before measurement. In a preferred embodiment at least part of the solid phase is provided in the form of magnetic beads. In this embodiment the solid phase can be mixed with the sample thereby creating a longer reaction time, a better sensitivity and a higher speed of the assay.
