Abstract: A method of forming a microelectronic device comprises forming a preliminary stack structure over a source structure. The preliminary stack structure comprises a vertically alternating sequence of insulative material and sacrificial material arranged in preliminary tiers. The method comprises forming a staircase structure having steps comprising edges of at least some of the preliminary tiers of the preliminary stack structure, forming implant regions within exposed portions of the sacrificial material at the steps of the staircase structure, forming openings extending through the preliminary stack structure to the source structure and within a horizontal area of the staircase structure, replacing portions of the sacrificial material with conductive structures, forming strapping structures comprising conductive material, at locations vacated by the implant regions, laterally adjacent to the conductive structures at the steps of the staircase structure, and forming conductive contacts within the openings.

Abstract: Methods, systems, and devices for merged cavities for conductor formation in a memory die are described. An array of cavities may be formed through a stack of material layers of a memory die, and conductors may be formed at least in part by merging some of the cavities of the array. Such cavities may be sized in accordance with a relatively smallest feature that implements a subset of such cavities, and a smallest associated feature may be formed using a first subset of the array of cavities. Conductors may be formed at least in part by merging two or more cavities of a second subset of the array of cavities using a material removal operation to remove portions of the stack of material layers. Such merging may support conductors being formed with a cross-section that is greater than a cross-section of other features formed using such cavities that are not merged.

Abstract: Methods, systems, and devices for NAND staircase landing pads conversion are described. A memory device may include one or more lateral word line contacts that may couple a word line with a conductive pillar that traverses a stack of materials of the memory device. The use of the lateral word line contact may allow for a conductive pillar to be coupled with a target word line without requiring an end of the conductive pillar to be placed directly on the word line. Additionally, the memory architecture described herein may allow for the target word line to be coupled with CMOS circuitry via a first conductive pillar without the use of a second conductive pillar, as the first conductive pillar may traverse the stack of materials and be coupled with the CMOS circuitry. Therefore, total quantity of conductive pillars may be reduced, and the risk of manufacturing errors may be lowered.

Abstract: A system and method for deriving information on disease in vascular segments for example mean pressure, drop in mean pressure and/or hydraulic resistance, from such measured waveforms is described. The waveforms can, for example, be measured non-invasively using Doppler ultrasound or magnetic resonance techniques. Form Factors (Vff, Pff) for the velocity waveform and the central arterial pressure are determined.

Abstract: A system for determining peripheral artery disease and method of use for determining the presence or absence of peripheral vascular disease and the severity of the disease in particular vascular segments. The System for determining peripheral artery disease and method of use includes a continuous wave Doppler transceiver which generates a digitized version of quadrature detected stereo audio and is coupleable to a waveform converter and processor. The waveform converter and processor provides filtering, time domain to frequency domain conversion, gain control, and statistical processing of the converted Doppler Stereo audio and is operationally coupled to a display for presenting results to a technician.

Abstract: A collapsible wheelbarrow has two side sections each of which has a generally rectangular load-containing wall, the two walls being hinged together about their lower edges. A tube projects forwardly from each wall to serve as a wheel support, and rearwardly to serve as a handle. A triangular front wall is pivoted to the two walls, the front wall being in two parts which are hinged together. The wheelbarrow may be opened out for normal use, or may be folded so as to be substantially flat, for storage or transport.

Abstract: A sawmill serving to cut logs into lengths which will allow for maximum use of the wood has a support for the log to be sawn. A number of saws are arranged alongside the supported log for individual lateral movement longitudinally of the log. Associated with the support is a locating device for determining the position of the log end relative to a reference datum line extending across the support. An electronic scanner surveys the log as it is delivered to the support and obtains log profile data which is fed to a computer. The computer has a memory in which is stored desirable cutting data as related to the reference datum line and the log profile data. A signal is sent by the computer to each of the saws whereupon the saws take up positions which will result in the log being cut into optimum random lengths.
