摘要:
A phase line tilt calculating unit (actual measurement) receives phase characteristics Pa(f) and Pb(f) outputted from frequency conversion units, and calculates phase difference characteristics of actual measurement based on a phase difference on each frequency component between the phase characteristics. A phase line tilt calculating unit (model) calculates phase difference characteristics between a transfer function Ga(f) and a transfer function Gb(f) calculated by a transfer function calculating unit, and outputs the calculated phase difference characteristics to a search unit. The search unit fits a variable k and determines a variable kopt (optimum solution) in which a tilt g(k) and a tilt gexp substantially match each other. The variable kopt is an index indicating a degree of arterial sclerosis of a subject.

In each of the information processing apparatuses connected to each other via a network, there is arranged a quality of service (QOS) table to which functions and performance thereof are registered. When an information processing apparatus is additionally linked with the network, a QOS table thereof is automatically registered to a local directory of the network such that an agent converts the contents of the QOS table into service information to be supplied via a user interface to the user. Thanks to the operation, information of functions and performance of each information processing apparatus connected to the network is converted into service information for the user. Consequently, the user can much more directly receive necessary services.

An ankle-blood-pressure measuring apparatus for measuring a blood pressure of an ankle of a living subject, including an inflatable cuff which is adapted to be worn on the ankle of the subject; a cuff-pressure changing device which decreases a pressure in the cuff from a pressure higher than a systolic blood pressure of the ankle; a distal-pulse-wave detecting device which is adapted to be worn on a distal portion of the subject that is located on a distal side of the ankle and detects a distal pulse wave produced from the distal portion; an increasing-point detecting device for detecting at least one increasing point where a magnitude of the distal pulse wave continuously detected by the distal-pulse-wave detecting device when the pressure of the cuff is decreased by the cuff-pressure changing device, significantly increases; and an ankle-blood-pressure determining device which determines a pressure of the cuff when the increasing-point detecting device detects the second increasing point, as a systolic blood pressure of one of a plurality of tibial arteries of the ankle of the subject that has stenosis.
