  • Patent number: 10485631
    Abstract: The length of an optical fiber from a portion aligned with the rear end of an insertion needle to a fixing portion is a length obtained by adding a predetermined extra length to a linear distance between the rear end of the insertion needle in a case where the insertion needle is located at a protruding position (insertion position) and an optical fiber fixing position of a grip portion. There is provided a fiber feeding adjustment mechanism that suspends the optical fiber with a first suspension portion and a second suspension portion so as to make a detour in a state in which there is no slack, and changes the detour length continuously according to the movement of the insertion needle in a case where the insertion needle moves between the retracted position and the protruding position, thereby maintaining a state in which the optical fiber is suspended without slack.

  • Patent number: 10470716
    Abstract: According to one configuration, a system includes sensor hardware and signal processor resource to monitor and analyze bio-media (such as blood and/or other matter) of a person under test. During operation, the sensor hardware monitors the bio-media of the person under test and produces an output. The monitored output (such as one or more signals) varies in magnitude based at least in part on person-induced movement. The signal processor resource analyzes the output produced by the sensor hardware. Based on the analysis, and detected variation in the output of the sensor hardware as caused by the person's movement, the signal processor resource produces a setting for a biometric parameter of interest associated with monitoring the bio-media. Note that the system as described herein can be used to measure different biometric parameters of interest such as venous blood oxygen content, vein stiffness, etc.
