Abstract: This application provides an accumulator, a multiplier, and an operator circuit, and relates to the field of electronic technologies, to reduce an area and power consumption of the accumulator. The accumulator includes W compressor layers, where W is an integer greater than or equal to 1. The W compressor layers include at least one first compressor layer. In an input array of each first compressor layer, a first array includes a plurality of positive-phase bits, and a second array includes a plurality of negative-phase bits. Each first compressor layer includes a first compression circuit configured to compress the first array and a second compression circuit configured to compress the second array. To be specific, bits with different phases in the input array of each first compressor layer are compressed by different compression circuits.

Abstract: A multiplier implements multiplication of a first value and a second value, and includes P precoders, P encoder groups, and a compressor, where each precoder is configured to: precode at least two bits in the second value, to output a selection signal group; each encoder group is configured to: encode the first value and a selection signal group output by a precoder corresponding to the encoder group, to output a partial product item; the P encoder groups include a first encoder group, a first encoder of the first encoder group is configured to: encode a first selection signal group, a least significant bit in the first value, and a first sign bit, to obtain a first partial product and a first output sign bit, the first selection signal group is a selection signal group output by a first precoder, and the first precoder corresponds to the first encoder group.

Abstract: A method of assembling a vehicle component, a system for assembling a vehicle component, and a vehicle component assembly. A blank is formed from a steel sheet, wherein the steel sheet includes a coating on a surface. The coating is removed from a first interface surface of the blank and the blank is stamped either prior to or after removing the coating. The first dynamic interface surface is arranged relative to a second interface surface and thermally joined to form a joint.

Abstract: A system for increasing joint strength and reducing embrittlement in a resistance spot weld of metal workpieces is disclosed. The system comprises a stackup of first and second metal workpieces, and an interface member disposed between the first and second metal workpieces. The interface member comprises a peripheral wall defining a hollow inner portion. The peripheral wall has a first open end extending to a second open end. The first open end is in contact with the first metal workpiece defining a first weld portion thereon. The second open end is in contact with the second metal workpiece defining a second weld portion thereon. The system further comprises a first electrode configured to contact the first metal workpiece to heat the peripheral wall at the first weld portion and join the first metal workpiece with the first open end of the peripheral wall.

Abstract: A hot formed joined blank includes a first metal blank having an ultimate tensile strength of ?about 1300 MPa to ?about 2000 MPa and defining a first surface, a second metal blank having an ultimate tensile strength of ?about 400 MPa to ?about 1200 MPa and defining a second coated surface having a coating disposed thereon. The coating includes aluminum and silicon or in alternative variations, zinc.

Abstract: A sheet blank includes a core substrate having a generally planar shape with opposed first and second sides. The core substrate is made of high-strength steel containing at least two of ferrite, martensite, bainite, and austenite and having an ultimate tensile strength of at least 490 MPa. A respective decarburized layer of the high-strength steel is formed on each of the first and second sides of the core substrate, wherein each respective decarburized layer contains a minimum ferrite content of at least 80 volume % ferrite and has a respective thickness of 5 to 100 microns. A respective transition layer of the high-strength steel may be formed between the core substrate and each respective decarburized layer, with each transition layer having a respective inner transition layer abutting the core substrate and a respective outer transition layer abutting the respective decarburized layer.

Abstract: A process for the preparation of ranolazine comprises the step of condensing N-(2,6-dimethylphenyl)-1-piperazinyl acetamide with a compound of formula (I) to obtain ranolazine, in which X is chlorine or bromine Ranolazine is prepared by condensing ring-opening halide which replaces epoxide in this process.
