Masked and controlled ion implants, coupled with annealing or etching are used in CVD formed single crystal diamond to create structures for both optical applications, nanoelectromechanical device formation, and medical device formation. Ion implantation is employed to deliver one or more atomic species into and beneath the diamond growth surface in order to form an implanted layer with a peak concentration of atoms at a predetermined depth beneath the diamond growth surface. The composition is heated in a non-oxidizing environment under suitable conditions to cause separation of the diamond proximate the implanted layer. Further ion implants may be used in released structures to straighten or curve them as desired. Boron doping may also be utilized to create conductive diamond structures.

Methods and apparatus for managing data storage in hybrid memory devices utilizing single level and multi level memory cells. Logical addresses can be distributed between single level and multilevel memory cells based on a frequency of write operations performed. Initial storage of data corresponding to a logical address in memory can be determined by various methods including initially writing all data to single level memory or initially writing all data to multilevel memory. Other methods permit a host to direct logical address writes to single level or multilevel memory cells based on anticipated usage.

The disclosure relates generally to production of lithography masks such as used in mass production of monolithic integrated circuits (IC's). Layers of such IC's often need to be filled with dummy-fill. In accordance with the disclosure, dummy-objects are first generated by a conventional flat-fill technique and then they are automatically surrounded by outlines that are substantially wrinkle-free. The outlines are cleared of the original flat-fill and then used as areas that are to be automatically tiled by an auto-tiling program. Tiles are then re-filled with array definitions of regularly-spaced dummy-objects. The arrays consume less data storage space than do the original, individually-specified (flat-filled) dummy-objects. The array data is appended to layout data of functional objects in a layer of the integrated monolithic device (IC) to thereby generate a dummy-filled tapeout file. The dummy-filled tapeout file is subjected to pre-tapeout rules checking and then transmitted via a network to a mask house for production of a corresponding lithography mask. The lithography mask is used to mass produce corresponding integrated circuits.

A localization mechanism, or fixture, is used in conjunction with a breast coil for breast compression and for guiding a core biopsy instrument during prone biopsy procedures in both open and closed Magnetic Resonance Imaging (MRI) machines. The localization fixture includes a three-dimensional Cartesian positionable guide for supporting and orienting an MRI-compatible biopsy instrument, and in particular a sleeve, to a biopsy site of suspicious tissues or lesions. A depth stop enhances accurate insertion, and prevents over-insertion or inadvertent retraction of the sleeve. The sleeve receives a probe of the MRI-compatible biopsy instrument and may contain various features to enhance its imagability, to enhance vacuum and pressure assist therethrough, and marker deployment etc.

A catheter product package and method of forming same in which the package comprises a sheet material wrapped about the catheter product to form a package for the catheter product. The catheter product extends generally longitudinally within the package, and the sheet material extends from a point beyond the proximal end to a point beyond the distal end of the catheter product. The sheet material of the package is wrapped about the catheter product in a manner defining confronting proximal end edges, confronting distal end edges, and confronting side edges. The confronting proximal end edges, distal end edges and side edges of the sheet material are joined by a seal after the sheet material is wrapped about the catheter product to define a sealed cavity. The sheet material has a tear strip affixed to it which causes the sheet material to tear along the tear strip to thereby cause the package to open along an intended opening line. A method of forming a package for a catheter product comprises the steps of providing a sheet material for the package and placing the catheter product on the sheet material. It also includes affixing a tear strip to the sheet material and wrapping the sheet material around the catheter product. Further, the method includes the step of sealing the sheet material to form a sealed cavity with the catheter product being disposed within the sealed cavity.

An obturator as part of a biopsy system enhances use with Magnetic Resonance Imaging (MRI) by indicating location of a side aperture in an encompassing cannula. The cannula (e.g., detached probe, sleeve sized to receive a core biopsy probe) includes a side aperture for taking a tissue sample. When the obturator is inserted in lieu of the biopsy device into the cannula, a notch formed in a shaft of the obturator corresponds to the side aperture. A dugout trough into the notch may further accept aqueous material to further accentuate the side aperture. In addition, a series of dimensionally varied apertures (e.g., wells, slats) that communicate through a lateral surface of the shaft and that are proximal to the side aperture receive an aqueous material to accentuate visibility in an MRI image, even in a skewed MRI slice through the cannula/obturator.

A data bus circuit for an integrated circuit memory includes a 4-bit bus per I/O pad that is used to connect the memory with an I/O block, but only two bits per I/O are utilized for writing. Four bits per I/O pad are used for reading. At every falling edge of an input data strobe, the last two bits are transmitted over the bus, which eliminates the need for the precise counting of input data strobe pulses. The data bus circuit is compatible with both DDR1 and DDR2 operating modes.

An electrolytic cell includes a container for holding an electrolyte. A conductively doped single crystal diamond anode electrode is positioned to be disposed within the electrolyte, as is a conductive cathode electrode. Conductors are coupled to the electrodes for coupling to a power supply. An electrolyte inlet and an electrolyte outlet are coupled to the container for causing electrolyte to flow past the electrodes. The anode electrode is downstream from the cathode electrode in one embodiment, such that an electrolyte comprising water is purified by generation of oxygen and/or ozone.
