  • Publication number: 20250038195
    Abstract: A positive electrode active material in a form of a single particle includes a lithium transition metal oxide in a form of a single particle, a coating portion containing cobalt which is formed on the lithium transition metal oxide in the form of a single particle, and LiCoO2 in a form of an island which is discontinuously formed on a surface. A ratio of an intensity of a peak ranging from 550 cm?1 to 620 cm?1 corresponding to an A1g vibration mode of LiCoO2 to an intensity of a peak ranging from 500 cm?1 to 600 cm?1 corresponding to an A1g vibration mode of LiNiO2 in a Raman spectrum of the surface is in a range of 0.1 to 1. Also provided is a method of preparing a positive electrode active material in a form of a single particle.

  • Publication number: 20220114453
    Abstract: A neural network pruning method includes: acquiring a first task accuracy of an inference task processed by a pretrained neural network; pruning, based on a channel unit, the neural network by adjusting weights between nodes of channels based on a preset learning weight and based on a channel-by-channel pruning parameter corresponding to a channel of each of a plurality of layers of the pretrained neural network; updating the learning weight based on the first task accuracy and a task accuracy of the pruned neural network; updating the channel-by-channel pruning parameter based on the updated learning weight and the task accuracy of the pruned neural network; and repruning, based on the channel unit, the pruned neural network based on the updated learning weight and based on the updated channel-by-channel pruning parameter.

  • Patent number: 7541916
    Abstract: A power supply using a static magnetic field of a tire pressure monitoring system is provided. The power supply includes: a static magnetic field generator installed at a car position adjacent to a tire, and generating the static magnetic field; and an EMF (ElectroMotive Force) coil installed at the tire, and generating an induced electromotive force by the generated static magnetic field and a relative motion resulting from rotation of the tire, and providing the generated electromotive force to the transmitter and the sensor.

  • Patent number: 7081868
    Abstract: The present invention relates to a reception antenna structure of a tire pressure monitoring system. The reception antenna is implemented using a cable-type antenna connected to a receiver of the tire pressure monitoring system. The cable-type antenna enables a mounting position of the antenna to be freely changed and improves a reception rate for measured data about temperature and pressure of a tire, that is modulated into data in the UHF band and transmitted to the outside of the tire in a wireless manner by a transmitter.

  • Patent number: 5872835
    Abstract: A data interface circuit for portable radio terminal equipment having wire and radio data communication functions, thereby capable of being applied to a variety of communication systems. For a communication using a radio network, the signal type is changed from a differential-ended-signal (DES) type highly influenced by noise to a single-ended-signal (SES) type hardly influenced by noise by an operation of the radio interface unit, thereby enabling the redundancy to noise to be increased. Furthermore, it is possible to provide various audio services by the audio signal processing control unit.
