A measuring instrument that includes a tube 21 having a female thread 211 and a spindle 3 having a lead screw 31 screwing with the female thread 211 and capable of being advanced and retracted in an axial direction along with rotation around the axial center, and measures dimensions etc. of a workpiece according to displacement in an axial direction of the spindle 3 based on a rotation amount of the spindle 3. According to this measuring instrument, a pitch P of the lead screw 31 is twice as large or more than the difference between an external diameter R and a core diameter r thereof, and the difference between the external diameter R and the core diameter r is one-fifth or less of the external diameter R. Because of the lead screw 31 with the large pitch, the spindle 3 can be moved at high speed, thus enhancing operational performance of the measuring instrument.

When emitted light from LED 31 is incident on photodiodes 32 and 33 with luminance Pa and Pb, currents ia and ib are generated according to luminance Pa and Pb. When outside light is incident through the finger tissues on photodiodes 32 and 33 with luminance Pc, current ic is produced. The current i1 (=ia+ic) generated by photodiode 32, and the current i2 (=-ib-ic) generated by photodiode 33, are added at node X, and the current ic corresponding to outside light is thus cancelled. In addition, photodiodes 32 and 33 are disposed at different distances from LED 31. As a result, the current flowing to opamp 34 is current ia corresponding to luminance Pa because luminance Pb is extremely low. The opamp 34 then applies a current voltage conversion to generate pulse wave signal Vm.

An object of the present invention is to provide a method, an apparatus and a system for automatically recognizing motions and actions of moving objects such as humans, animals and machines.Measuring instruments are attached to an object under observation. The instruments measure a status change entailing the object's motion or action and to issue a signal denoting the measurements.

A signal processing unit for motion / action recognition correlates the extracted characteristic quantity with reference data in a database containing previously acquired characteristic quantities of motions and actions. The motion or action represented by the characteristic quantity with the highest degree of correlation is recognized and output.

An apparatus for transferring two frequencies of electromagnetic energy to and from a portion of a living body for the purpose of blood oxygen saturation measurements. The two frequencies of electromagnetic energy are transferred to the portion of the living body through a single optical fiber cable (which could be a bundle) to a coupler and then through a short section of optical cable to an optical element adjacent to the portion of the living body. After the two frequencies of electromagnetic energy are transmitted through the portion of the living body they are received by another optical element and transported away from the portion of the living body to a coupler through a short section of optical cable where they may be converted to electrical signals. Alternatively, the two frequencies of electromagnetic energy are carried away from the coupler. The signals from the coupler (whether they are electromagnetic signals or electrical signals) are directed to a measurement instrument, which through an adapter may be a conventional measurement instrument known in the prior art or a measurement instrument specifically designed for use with the signals produced at the coupler. The two short sections of optical cable and the two optical elements adjacent to the portion of the living body and the coupler are combined to form a disposable probe. Alternatively, the disposable probe can include a transducer to convert the transmitted optical energy to electrical signals.
