A method of determining stiffness index of an arterial network is disclosed. The method comprises the steps of: obtaining a pulse waveform related to the arterial network; estimating a source pulse based on at least one predetermined feature of the pulse waveform; determining a plurality of characteristics of the pulse waveform based on a relationship between the pulse waveform and the source pulse; and calculating the stiffness index of the arterial network based on the plurality of characteristics of the pulse waveform. An arterial stiffness index measuring device employing the above methodology is also disclosed therein.

A method for operating a lock in a computing system having plural processing units and running under multiple runtime environments is provided. When a requester thread attempts to acquire the lock while the lock is held by a holder thread, determine whether the holder thread is suspendable or non-suspendable. If the holder thread is non-suspendable, put the requester thread in a spin state regardless of whether the requester thread is suspendable or non-suspendable; otherwise determines whether the requester thread is suspendable or non-suspendable unless the requester thread quits acquiring the lock. If the requester thread is non-suspendable, arrange the requester thread to attempt acquiring the lock again; otherwise add the requester thread to a wait queue as an additional suspended thread. Suspended threads stored in the wait queue are allowable to be resumed later for lock acquisition. The method is applicable for the computing system with a multicore processor.

Techniques for effectively and accurately measuring psychological influencing factors, such as the white coat effect and mental stress, that may affect or otherwise influence biometric measurements, such as blood pressure measurements, are described. Embodiments of a measurement validation system herein may utilize a method for determining an artery location on a living subjects skin and positioning a tonometry pressure sensor on the artery location for tonometric blood pressure measurement to obtain pressure pulse data for a subject. In operation according to embodiments, measurement logic of a measurement validation system may utilize the pressure pulse data to extract blood pressure data, heart rate data, blood pressure variability data, and heart rate variability data. The foregoing data may be utilized in identifying whether the blood pressure measurement properly and accurately reflects the situation of the subject.
