Abstract: A therapeutic device includes a catheter and a temporary vessel occluder. The vessel occluder has a plurality of elastic strands extending in a tubular arrangement from the first end to the second, a primer on the strands, and a polymer filter coating over the primer. The primer is unevenly distributed to the plurality of elastic strands between the plurality of elastic strands. The filter coated is applied over the primer and on the strands. A portion of the polymer coating may be removed.

Abstract: A vascular treatment device for use in a vessel includes a catheter and a microvalve occluder. The occluder includes braided elastic strands, each with a proximal portion, a central portion, and a distal portion, that are fixed to the outer surface of the catheter. The elastic strands. In an embodiment, the distal portions are attached circumferentially about an outer surface of the catheter at a location toward the distal end of the catheter, the central portions extend proximal and radially outward from the distal end, and the proximal portions of the strands are inverted back radially within the central portions are and coupled circumferentially about the outer surface of the catheter at a location proximally displaced from the distal portions. The proximal portion of the microvalve is coated in a fluid-impermeable membrane, and the distal portions of the strands are substantially uncoated.

Abstract: A treatment device for use in a vessel includes a catheter and a microvalve. A flexible low friction reconfigurable cover is attached at or adjacent a distal end of the microvalve. The cover is deployed between the occluder and the vessel wall to intervene between the occluder and the vessel wall during movement of the occluder relative to the vessel wall to reduce occurrence of vascular spasm.

Abstract: The disclosure relates to the inherently selective mixed oxide deposition of a dielectric film on non-metallic substrates without concomitant growth on metallic substrates using a sequence of exposure to metal alkyl, heteroatom silacyclic compound, and water. The resulting films show much higher growth rates than corresponding metal oxide and inherent selectivity towards non-metallic surfaces. Films as thick as 14 nm can be grown on dielectric substrates such as thermal oxide and silicon nitride without any growth observed on metallic films such as copper and without the use of an inhibitor. Such dielectric-on-dielectric (DoD) growth is a critical element of many proposed fabrication schemes for future semiconductor device fabrication such as fully self-aligned vias.

Abstract: The selective deposition of a metal oxide or dielectric layer on non-metallic substrates without concomitant growth on metallic substrates using cyclic azasilanes, cyclic thiasilanes, or cyclic tellurasilanes to inhibit growth on the metal surface is described. Films over seven nanometers thick can be grown on dielectric substrates, such as thermal silicon dioxide and silicon, without any growth observed on metallic areas such as copper. Such dielectric-on-dielectric (DoD) growth is a critical element of many proposed fabrication schemes for future semiconductor device fabrication such as fully self-aligned vias.

Abstract: An apparatus is provided to access a weight vector of a layer in a sequence of layers in the DNN. The weight vector includes a first sequence of weights having different values. A bitmap is generated based on the weight vector. The bitmap includes a second sequence of bitmap elements. Each bitmap element corresponds to a different weight and has a value determined based at least on the value of the corresponding weight. The index of each bitmap element in the second sequence matches the index of the corresponding weight in the first sequence. A new bitmap is generated by rearranging the bitmap elements in the second sequence based on the values of the bitmap elements. The weight vector is rearranged based on the new bitmap. The rearranged weight vector is divided into subsets, each of which is assigned to a different PE for a MAC operation.

Abstract: There is disclosed a system and method of performing an artificial intelligence (AI) inference, including: programming an AI accelerator circuit to solve an AI problem with a plurality of layer-specific register file (RF) size allocations, wherein the AI accelerator circuit comprises processing elements (PEs) with respective associated RFs, wherein the RFs individually are divided into K sub-banks of size B bytes, wherein B and K are integers, and wherein the RFs include circuitry to individually allocate a sub-bank to one of input feature (IF), output feature (OF), or filter weight (FL), and wherein programming the plurality of layer-specific RF size allocations comprises accounting for sparse data within the layer; and causing the AI accelerator circuit to execute the AI problem, including applying the layer-specific RF size allocations at run-time.

Abstract: A collapsible disposable cat litter box comprises a collapsible closure means by which the used litter box can be sealed closed quickly for easy disposal. The box comprises a moisture-proof enclosure with collapsible closure means extending from the side walls of the enclosure. The collapsible closure means includes two rigid top panels and two foldable panels. The foldable panels are scored so that they may be pushed inward to close the top of the litter box quickly. The side panels also include a horizontal score line so that the upper portion of the side panels may be folded down to enhance the rigidity of the litter box.
