Abstract: A subject information acquiring apparatus includes a light source configured to radiate optical pulses coded by a predetermined number of pulse streams to a subject, a probe having a converting element configured to receive photoacoustic waves occurring from the subject, and configured to convert the received photoacoustic waves to electrical signals, and an information acquiring unit configured to decode a predetermined number of signals of the electrical signals output from the converting element and acquire characteristic information on the subject based on the decoded electrical signals, wherein the relative positions of the converting element included in the probe and the subject are changed before the radiation of the predetermined number of optical pulse streams completes, and the electrical signals to be decoded are partially redundant before and after the change of the relative positions of the converting element and the subject.

Abstract: A system monitoring statuses such as presence and absence of abnormality and lifetime of a machine component such as, for example, a bearing having rolling elements, includes: a plurality of determining units respectively connected with a plurality of sensors, and a control unit connected with the determining units. Each sensor is disposed on the machine component of the associated rolling bearing to detect an influence signal resulting from passage of the rolling element induced in the machine component. Each determining unit determines, according a process set-up condition, the presence and absence of an abnormality and lifetime of the machine component associated with the sensor in reference to an output signal from the sensors. The control unit collects a result of determination performed by each determining unit. In this way, with a simplified structure, monitoring can be achieved at a low cost, precisely and efficiently.

Abstract: A system for monitoring statuses such as presence or absence of abnormality and lifetime of a machine component such as, for example, a bearing having rolling elements includes a plurality of determining units 4 each connected with a plurality of sensors 3, and a control means 5 connected with the determining units 4. Each sensor is disposed on the machine component 1 of the associated rolling bearing for detecting an influence signal resulting from passage of the rolling element induced in the machine component 1. Each determining unit 4 determines according a process set-up condition the presence or absence of an abnormality, lifetime and others of the machine component 1 associated with the sensor 3 in reference to an output signal from such sensor 3. The control means 5 collects a result of determination performed by each determining unit 4. In this way, with a simplified structure, monitoring can be achieved at a low cost, precisely and efficiently.
