  • Publication number: 20240119055
    Abstract: Various devices, such as storage devices or storage systems are configured to perform on device semantic searching. The device includes a processor, a plurality of memory devices, a controller coupled to the memory devices, and an intelligent memory array logic. The intelligent memory array logic is configured to receive a query, extract contextual data from the query, determine a machine learning model for processing the query based on the extracted contextual data, generate a query vector based on the query and determined machine learning model, determine one or more relevant memory structures associated with the generated query vector, and pass in the query vector to the one or more determined relevant memory structures. The one or more relevant memory structures include feature data and one or more machine learning processing units configured to process the query vector and feature data to generate a comparison value.

  • Patent number: 11769548
    Abstract: A method includes setting an output of each memory cell in an array of memory cells to a same first value, decreasing power to the array of memory cells and then increasing power to the array of memory cells. Memory cells in the array of memory cells with outputs that switched to a second value different from the first value are then identified in response to decreasing and then increasing the power. A set of memory cells is then selected from the identified memory cells to use in hardware security.

  • Patent number: 7973917
    Abstract: The present invention relates to the technical field of measuring light source, specifically, to the method for measuring the luminous flux of LED. In the present invention, a reflecting cup is used as a collector of the luminous flux of LED. The collector has two sectional openings in the direction perpendicular to the symmetric axis thereof, which are positioned in the front and in the rear respectively, one of them positioned at the bottom end of the collector and having a smaller radius is used to input the light emitted by LED to be measured, the other positioned in the front end of the collector and having a larger radius is used to output the light to the detector placed in this position. Specifically, LED is fixed at the bottom end of the collector with a fixture, the light emitted by LED is directed toward the large opening of the collector, and the photometer is fixed closely at the large opening of the collector to receive light signals.

  • Patent number: 7532324
    Abstract: This invention belongs to the luminous flux measurement field, and especially relates to the equipment and method for LED's total luminous flux measurement with a narrow beam standard light source. The system for LED's total luminous flux measurement with a narrow beam standard light source in this invention comprises an integrating sphere, the light source, a narrow aperture fiber, a spectrometer and a driver for the light source. The light source is lighted by the driver. The narrow beam standard light source (both luminous flux standard and spectrum standard) is placed on the interior surface of integrating sphere, there is not any baffle in the sphere, and a narrow aperture fiber transfers the light to a multi-channel spectrometer which measures the spectrum distribution of LED and calculates its total luminous flux. The equipment in this invention is easy to use, has small error and low cost, and can achieve accurate results for LED's total luminous flux.
