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.

Abstract: A laser driver system is disclosed that includes a first monitor current output node, a power set node, and a first feedback path. The first monitor current output node provides a first monitor current output signal that is representative of one of a bias current and a modulation current of the laser driver system. The power set node receives a power ratio set signal that represents a desired relationship of a power required for the laser driver to produce a high power level threshold to a power required for the laser driver to produce a low power level threshold. The first feedback path extends from the first monitor current output node to the power set node, and may be used for adjusting the power set signal when the monitor current output signal becomes non-linear.
