  • Publication number: 20220230060
    Abstract: A neuromorphic device includes: a neuron block unit including a plurality of neurons; a synapse block unit including a plurality of synapses; and a topology block unit including a plurality of parallel Look-Up Table (LUT) modules including pre and post neuron elements configured with addresses of a presynaptic neuron and a postsynaptic neuron. Each of the plurality of neurons has an intrinsic address, each of the plurality of synapses has an intrinsic address. The parallel LUT module is partitioned based on a first synapse address among synapse addresses, and each of the partitions is indexed based on a second synapse address among the synapse addresses.

  • Publication number: 20220230059
    Abstract: Provided is a method of operating a neuron in a neuromorphic system. The method includes evaluating a membrane potential value at a corresponding time when receiving an input spike, time-modulating a synaptic weight of the membrane potential value and converting the time-modulated synaptic weight into a membrane potential value at a reference time, and generating an output spike when the membrane potential value at the reference time exceeds a certain threshold value. The membrane potential value at the reference time is represented by a floating point number including a predetermined bit of exponent and mantissa, and the floating point number includes time information. The method further includes accessing a memory and scanning a neural state variable when a timer is updated to “0” to update the neural state variable to an updated value at a reference time.

  • Publication number: 20150116242
    Abstract: Disclosed herein is a touch sensor. The touch sensor includes: a window substrate; a base substrate having one surface formed so as to be bonded to the window substrate and the other surface having a first electrode pattern formed thereon; a bezel formed along an edge of the base substrate; an insulating layer applying the electrode pattern while filling between the bezel and the bezel; and a second electrode pattern formed on the insulating layer.

  • Publication number: 20150103271
    Abstract: Disclosed herein is provided with a touch sensor, including: a window substrate; a first bezel layer formed at an edge portion of the window substrate and formed of at least one layer; and a resin layer disposed on the first bezel layer and the window substrate. The touch sensor further includes a second bezel layer disposed on the resin layer, at a position corresponding to the first bezel layer and the resin layer is made of a transparent material having a refractive index lower than that of the first bezel layer and the second bezel layer. As described above, the plurality of bezel layers and the resin layer are stacked together to form a difference in refractive index, thereby implementing a clear color even by the thinner bezel layer.

  • Publication number: 20100214721
    Abstract: An electric double layer capacitor package includes a package body including a groove region formed by removing a portion from a surface thereof, an electric double layer capacitor disposed in the groove region of the package body, and including first and second electrodes and an ion permeable separator disposed between the first and second electrodes, and first and second conductive vias each disposed in an inner portion of the package body and each having one end connected to one of the first and second electrodes, respectively and the other end extending from the one end toward a bottom surface of the package body in the case that the surface is defined as an upper region of the package body. The electric double layer capacitor package can be surface-mounted without using an additional structure. The use of the electric double layer capacitor package achieves a reduction in thickness and mounting area, thereby contributing to the production of lighter and smaller products.
