  • Patent number: 11131621
    Abstract: An analysis device includes an optical disc drive, a gate information processing unit, a detection circuit, and a gate shift processing unit. The optical disc drive rotates a specimen analysis disc and detects a measurement radial position for an optical pickup. The detection circuit generates gate signals shifted by a gate shift amount in each measurement radial position in a rotating direction of the specimen analysis disc, and generates count values of the respective gate signals. The gate shift processing unit divides a gate signal-corresponding region of the corresponding gate signal by a unit gate shift amount in the rotating direction of the specimen analysis disc to define a plurality of divided regions and sets count values of the divided regions based on the count values of the gate signals.

  • Patent number: 11118910
    Abstract: An updating unit updates an attitude represented by quaternion by defining an initial attitude represented by quaternion as an initial value, and successively substituting output values of the triaxial gyro sensor. A second converter converts the attitude represented by quaternion into an attitude in the Euler angle representation. An angular speed derivation unit derives an angular speed based on a time-dependent change in the attitude in the Euler angle representation. The output unit outputs an angular speed derived based on an output value of a monoaxial gyro sensor, when a difference between a pitch angle derived based on the output value of the triaxial acceleration sensor and the output value of the second converter and a pitch angle from the second converter is equal to or larger than a threshold value.
