  • Patent number: 11763162
    Abstract: A dynamic gradient calibration method for a computing-in-memory neural network is performed to update a plurality of weights in a computing-in-memory circuit according to a plurality of inputs corresponding to a correct answer. A forward operating step includes performing a bit wise multiply-accumulate operation on a plurality of divided inputs and a plurality of divided weights to generate a plurality of multiply-accumulate values, and performing a clamping function on the multiply-accumulate values to generate a plurality of clamped multiply-accumulate values according to a predetermined upper bound value, and comparing the clamped multiply-accumulate values with the correct answer to generate a plurality of loss values. A backward operating step includes performing a partial differential operation on the loss values relative to the weights to generate a weight-based gradient. The weights are updated according to the weight-based gradient.

  • Patent number: 11495287
    Abstract: A memory unit is controlled by a first word line and a second word line. The memory unit includes a memory cell and a transpose cell. The memory cell stores a weight. The memory cell is controlled by the first word line and includes a local bit line transmitting the weight. The transpose cell is connected to the memory cell and receives the weight via the local bit line. The transpose cell includes an input bit line, an input bit line bar, an output bit line and an output bit line bar. Each of the input bit line and the input bit line bar transmits a multi-bit input value, and the transpose cell is controlled by the second word line to generate a multi-bit output value on each of the output bit line and the output bit line bar according to the multi-bit input value and the weight.

  • Patent number: 10916175
    Abstract: A method for correcting uniformity of a panel is provided. A display panel is set with four color patterns respectively, and respective raw data of the four color patterns are respectively measured by an optical instrument. Three primary color chromaticity variations are obtained based on the raw data of each of the four color patterns. A chromaticity uniformity table is obtained based on the chromaticity variations of three primary colors and chromaticity intensity. A proportional calculation is executed for the chromaticity uniformity table to obtain a luminance comparison table. A luminance uniformity table is obtained based on the chromaticity uniformity table, the luminance comparison table, and luminance intensity. The display panel adjusts an output signal based on the chromaticity uniformity table.

  • Patent number: 5549224
    Abstract: A liquid medicine container includes a container body having threaded neck with an opening formed thereon for the entry of a liquid medicine into the container body. A seal member is fit into the opening to seal it. A through hole is formed on the seal member to be in fluid communication with the interior of the container body. The neck has a circumferential flange formed thereon with two recesses formed on the flange. The neck also has a groove formed thereon and extending in a direction substantially normal to the threading of the neck from a point close the circumferential flange, crossing the neck threading, to a point close to the opening. A cap member has an open end with segmented threading formed therein to be engageable with the neck threading for tightening the cap member on the neck wherein the edge of the open end of the cap member is in contact engagement with the flange and two bosses formed on the edge of the open end of the cap member received within the recesses formed on the flange.
