Accordingly, it is possible to suppress erroneous detection caused by diffuse reflection of light and accurately detect a full load condition.

An image processing device includes an input unit to receive an input image, a feature amount extraction unit to extract a feature amount from the input image, an object region detection unit to detect an object region in the image through use of the feature amount, an object end-point estimation unit to estimate coordinates of an end point of an object in the object region, an object bridging unit to calculate a trajectory complementing a space between end points in two object regions on the input image, a same-object determination unit to determine, from luminance value transition on the trajectory, whether the two object regions are included in the same object, an object region correction unit to correct the object region output by the object region detection unit based on a determination result output by the same-object determination unit, and an output unit to output the corrected object region.

To provide: a device which performs spectroscopic measurement on a suspension liquid handled in the field of pharmaceutical products, foods, or chemistry without taking out the suspension liquid from the inside of a pipe, and is capable of accurate measurement even when the device is attached to pipes of various shapes and materials; and a measurement condition adjustment method, the following configuration is adopted. A measurement device for measuring an optical spectrum of a liquid flowing in a pipe provided with a window material includes: a measurement probe having a light irradiation unit and a light reception unit; and a movement mechanism for moving the measurement probe, in which the movement direction of the measurement probe includes a rotation angle for changing the direction of the probe and a direction different from the axial direction of the pipe. The position of the measurement probe is adjusted by using both or one of the S/N ratio and the intensity of the measured values at the wavelength of interest.

In the prior art, the reliability of a measurement result is lowered by the deterioration of an ISE reagent remaining in a flow passage in the standby time of an electrolyte analysis unit. To solve this problem, when receiving an instruction to measure a patient sample requiring measurement using an electrolyte analysis unit 8, this automatic analysis device 1 determines deterioration of a residual reagent remaining in the flow path of the electrolyte analysis unit prior to measurement of the patient sample when the standby time of the electrolyte analysis unit is equal to or greater than a predetermined time.

A battery state diagnosis method and a battery state diagnosis device are provided, which achieve a highly accurate battery capacity deterioration diagnosis when a diagnosis target is a battery system, such as a battery system using a LiFePO<4>-based active material for the positive electrode, that exhibits little voltage change in response to a change in the state-of-charge. A battery state diagnosis method is for diagnosing a deterioration state of a secondary battery mounted on equipment, and includes: a data acquisition step of acquiring pieces of data about a voltage, a current, and a temperature of the secondary battery from the equipment in operation; a table creation step of creating, based on the acquired pieces of data, a table including a state of health capacity and a state of health resistance of the secondary battery; and a diagnosis step of diagnosing, using the created table, a deterioration state of the secondary battery.

This automatic analysis device calculates, for each of a plurality of analysis tanks 106, a target number of uses of the analysis tank per predetermined period of time on the basis of the number of remaining executable measurements of an ion selective electrode 112 and a remaining period of time up to an expiration date thereof, and when there are a plurality of analysis tanks usable for an analysis request, determines a ratio of usage for each analysis tank on the basis of a ratio of the target number of uses of each of the plurality of analysis tanks usable for the analysis request. This allows as many of the number of remaining executable measurements as possible to be used in the automatic analysis device comprising the plurality of analysis tanks before the expiration date of the ion selective electrode.

Provided is an automatic analyzer capable of accurately detecting an abnormality during aspiration even when an amount of a reagent used for analysis is small. An automatic analyzer includes: a dispensing mechanism configured to dispense a reagent from a reagent container to a reaction container; a control unit configured to control the dispensing mechanism to aspirate an amount of the reagent used for analysis, the amount including at least a second predetermined amount in addition to a first predetermined amount, then discharge the second predetermined amount of the reagent to the reagent container, and then discharge the first predetermined amount of the reagent to the reaction container; and a pressure sensor configured to measure pressure in the dispensing mechanism. The control unit determines whether the reagent is normally aspirated based on a measurement value of the pressure sensor when the dispensing mechanism aspirates the reagent. When the first predetermined amount is equal to or larger than a first predetermined amount threshold value that is predetermined in advance, the second predetermined amount is a constant value regardless of the first predetermined amount. When the first predetermined amount is smaller than the first predetermined amount threshold value, the second predetermined amount is larger than the constant value.

A consumable storage vessel mount section has a first position and a second position. A consumable stored in a consumable storage vessel at the first position is used for a sample analysis. When the consumable storage vessel at the first position has been used, the consumable storage vessel at the second position is transferred to the first position. If it is determined that the consumable stored in the consumable storage vessel at the second position is unusable, the determination is made before starting the sample analysis whether it is possible to perform the sample analysis by using only the consumable stored in the consumable storage vessel at the first position, or it is necessary to use the consumables stored in the consumable storage vessels at the first and the second positions for performing the sample analysis. Hence, an interruption of an analysis that has been started using a first consumable resulting from unavailability of a second consumable owing to the validity term of the consumable in a standby state is avoided.
