  • Patent number: 11955154
    Abstract: A sense amplifier circuit includes a sense amplifier, a switch and a temperature compensation circuit. The temperature compensation circuit provides a control signal having a positive temperature coefficient, based on which the switch provides reference impedance for temperature compensation. The sense amplifier includes a first input end coupled to a target bit and a second input end coupled to the switch. The sense amplifier outputs a sense amplifier signal based on the reference impedance and the impedance of the target bit.

  • Publication number: 20240114632
    Abstract: A circuit board structure is provided. The circuit board structure includes a via hole, a conductive layer, and an alternate stacking of a plurality of circuit layers and a plurality of insulating layers. The via hole penetrates through the plurality of circuit layers and the plurality of insulating layers. The lateral ends of the plurality of insulating layers form the sidewall of the via hole. The conductive layer is conformally disposed within the via hole. The conductive layer exposes the first region of the sidewall and covers the second region of the sidewall. The sidewall extends in the longitudinal direction of the via hole and has no misalignments in the radial direction.

  • Publication number: 20240075558
    Abstract: A processing method of a single crystal material includes the following steps. A single crystal material is provided as an object to be modified. The amorphous phase modification apparatus is used for emitting a femtosecond laser beam to process an internal portion of the object to be modified. The processing includes using a femtosecond laser beam to form a plurality of processing lines in the internal portion of the object to be modified, wherein each of the processing lines include a zigzag pattern processing, and a processing line spacing between the plurality of processing lines is in a range of 200 ?m to 600 ?m, wherein after the object to be modified is processed, a modified layer is formed in the object to be modified. Slicing or separating out a portion in the object to be modified that includes the modified layer.

  • Publication number: 20180375737
    Abstract: A sensor estimation server and a sensor estimation method thereof are provided. The sensor estimation server receives first sensor values of deploying sensors to each of servers from the servers, and receives added sensor values of deploying added sensor to each of the servers from the servers. The sensor estimation server calculates correlations between the added sensor and the sensors based on the added sensor values and the first sensor values, and selects target sensors accordingly. The sensor estimation server calculates estimation parameters according to the added sensor values and target sensor values of deploying the target sensors to each of servers. The sensor estimation server receives second sensor values of deploying the target sensors to under-test servers from the under-test servers, and calculates a sensor estimation value based on the estimation parameters and the second sensor values.

  • Patent number: 9270953
    Abstract: An image capture unit includes an image sensor and a lens structure disposed proximate to the image sensor to focus an image onto the image sensor. A movable color filter grouping is disposed over the lens structure. The movable color filter grouping includes a plurality of N color filters arranged therein such that all light that is incident upon the image sensor through the lens structure is directed through only one of the plurality of N color filters of the movable color filter grouping per each exposure of the image sensor. A positioning device is attached to the movable color filter grouping to reposition the movable color filter grouping such that substantially all of the light that is incident upon the image sensor through the lens structure is directed through a different one of the plurality of N color filters for each successive exposure of the image sensor.
