  • Patent number: 9854976
    Abstract: The present invention provides a pulse wave velocity measurement method and system as well as an imaging device available for everyday use by general users at low cost with measurement accuracy less affected by posture or the like. The present invention simultaneously images different parts of a human body in a non-contact state by a single visible light camera and acquires continuous time series image data. Then, the present invention detects each pulse wave from the image data in the different parts of the human body based on a temporal change in pixel value of the different parts of the human body, and then calculates a pulse wave velocity of the human body based on a time difference between the pulse waves in the different parts of the human body.

  • Patent number: 8418572
    Abstract: A three-dimensional cam mechanism capable of selecting a cam guide surface shape freely to improve the degree of freedom for selecting a target locus on the follower side, transmitting power between orthogonal axes and performing a reversible operation. A three-dimensional cam guide surface (2 (3)) is formed in a cam (1), and the cam guide surface (2) is caused to guide a cam follower (6 (7)) formed at a predetermined angle at one end of a follower side link (4), so that the rotational movement of the cam (1) is translated into the swinging movement at the other end of the follower side link (4). Thus, smooth operations of the cam are obtained by the selection of the shape of a supporting member and by the free design of the cam guide surface shape, without being limited to the power transmission between the orthogonal axes or followed by backlash.

  • Patent number: 8210070
    Abstract: A reduction gear capable of satisfying, at high level, each of: realizing a high reduction ratio; preventing backlash by securing rotation smoothness; and carrying out compactification and weight saving of entire mechanism is provided. The reduction gear of the invention is a modified crown reduction gear, comprising: a pressing mechanism 16 operated to rotate; a fixed crown gear 2 fixed to an external member 15; a movable crown gear 1, wherein the difference in the number of teeth between the gears is one; and an output axis 3 flexibly attached to the gear 1. The gear 1 engages with the gear 2 at a slant by pressing-force provided from the mechanism 16. In this instance, contact locations of teeth of the gears 1 and 2 are dispersed at two places existing at both sides between which a gradient center line intervenes.
