  • Patent number: 6181369
    Abstract: A videoscope for dental or oral use comprises a grip portion, an insert portion, a light window formed in the wall of the insert portion for illuminating an object, an acceptance window formed in the wall of the insert portion for receiving reflected light from the object, an image sensor disposed in the tip of the insert portion for receiving the light from the object to generate an electric signal corresponding to the object image, a light source disposed in the grip portion, and a light guide for guiding light rays from the light source to the light window. The light guide is made of a transparent plastic material. The light guide has a condensing portion that condenses the light rays emitted by the light emitting member, a guiding portion in which the light rays can propagate by total reflection, and a shedding portion that sheds the propagated light rays through the light window.

  • Patent number: 6078829
    Abstract: The present invention provides a measuring apparatus for biological information which permits accurate determination for biological information without causing the subject much discomfort. The measuring apparatus for biological information of the present invention uses an ear receiver-shaped sensor element which is placed and held on the perimeter of the subject's external auditory meatus opening with the light emitter and the light receiver brought into contact with the subject. The light receiver detects the light projected to and passed through the subject. The apparatus is also provided with a signal processor which performs calculation for biological information of the subject on the basis of the intensity of light detected by the light receiver.

  • Patent number: 5745165
    Abstract: A compact and light-weight video scope camera offering easy magnification changing operations. A hollow insert portion continuous to a grip to be held by an operator is provided with an imaging system at the leading end. Operating an operation switch on the grip allows operational movement of a selection mechanism in the insert portion to cyclically or selectively select, from plural preset distance values, a distance between a lens and an image pickup device in the imaging system, corresponding to which distance, the lens or the image pickup device is moved relative to each other by an imaging system component of mechanism to set any one of predetermined magnification modes. This results a compact, light-weight video scope camera offering easy magnification changing operations. The invention is applicable to various video scope cameras for diagnosis and/or treatment in dentistry and orthopedics and also for industrial or educational use.
