    Abstract: Provided are light absorption spectrum correction devices, methods of manufacturing the light absorption spectrum correction devices, and methods of correcting a light absorption spectrum. The light absorption spectrum correction device includes: a light source configured to emit light; an attenuated total reflectance (ATR) crystal layer configured to contact a subject and provide an optical passage along which the light emitted from the light source travels to the subject; a pressure sensor configured to detect a contact pressure applied to the ATR crystal layer by the subject; a spectrum detector and analyzer configured to detect light emitted from the ATR crystal layer, form a light absorption spectrum based on the detected light, and determine an intensity of the light emitted from the ATR crystal layer; and a spectrum correction device configured to correct the light absorption spectrum based on the contact pressure.

    Abstract: Provided are a biosignal processing apparatus and a biosignal processing method. The biosignal processing apparatus includes: a first measurement module configured to detect a biosignal of a subject in a non-invasive manner in response to the biosignal processing apparatus being in contact with the subject; a second measurement module configured to measure a contact state with respect to the subject; and a controller configured to determine whether the contact state is equal to or greater than a reference value.

    Abstract: Disclosed are a non-invasive liver function testing apparatus and method. The non-invasive liver function testing apparatus includes a light source configured to irradiate light onto an object, a light detector configured to detect information about light reflected from the object, a raw data extractor configured to extract raw data, associated with at least one target material constituting the object, from the information detected by the light detector, and a data processor configured to extract liver function-related information, including a correlation with the at least one target material, from the raw data.

    IPC: G06F9/52

    CPC classification number: G06F9/526

    Abstract: Provided is a method of controlling access a shared resources when executing a first process that acquires a lock on the shared resource and adding a second process to a waiting queue. A determination is made on whether to deactivate preemption for the processor based on a priority of the second process, and based on determining to deactivate preemption for the processor, executing the first process until execution of the first process on the shared resource is completed, then retrieving the lock from the first process after execution of the first process on the shared resource is completed and reactivating preemption for the processor.
