An intraoral camera system is disclosed, which includes a dental mirror having a aperture for transmitting light therethrough, the aperture being provided in the center or any other part of the mirror by removing a reflective material therefrom. A CCD camera is secured on a back surface of the dental mirror in such a manner that the aperture coincides with its incident portion coincides with aperture in the dental mirror. A hand mirror shaped monitor is also provided for displaying image data received from the CCD camera via cable or radio, and a server is also provided that is capable of storing and outputting the image data any time onto the monitor, wherein even though a patient is laid down on a chair in a horizontal position, the patient or a third party can utilize the hand mirror shaped monitor to view an image which is very close to the image that a dentist views through reflection from the dental mirror having said CCD camera built therein.

An imaging device including a base on which an imaging element is provided, a cylindrically shaped plastic lens member holding a condensing lens at the inside, and a plastic barrel member in which the lens member can move in the axial direction and provided above the imaging element, wherein the barrel member and the lens member are affixed by laser welding, a method of production of the same, and an imaging device holding mechanism used for that production.

A fingerprint input apparatus includes scattered light and a two-dimensional image sensor. The scattered light is generated inside a finger having a fingerprint pattern in accordance with external light. The fingerprint pattern is made up of a ridge portion and a valley portion. The two-dimensional image sensor is made of a large number of light-receiving elements arranged in a two-dimensional array. The image of the fingerprint pattern is input to a light-receiving surface of the light-receiving element. The light-receiving element whose light-receiving surface is in substantially contact with the ridge portion detects as the ridge portion a bright portion where the scattered light emerging from the finger reaches at a high intensity. The light-receiving element whose light-receiving surface corresponds to the valley portion via a space detects as the valley portion a dark portion where the scattering light emerging from the finger reaches at a low intensity.

A lattice strain measuring method including the steps of: using a scanning transmission electron microscope 12 to apply convergent electron beams 34 to a sample 32 and obtain a convergent-beam electron diffraction image 36 of the sample 32; computing a lattice strain magnitude of the sample 32, based on the obtained convergent-beam electron diffraction image; and displaying the computed lattice strain magnitude, associated with an electron microscope image of the sample 32. A scanning transmission electron microscope 12 is used, whereby electron beams 34 are caused to scan to thereby suitably set an incidence position. Accordingly, the incidence position of the electron beams can be displaced at a nanometer-order pitch accurately in a short period of time. The use of a scanning transmission electron microscope 12 requires no image forming lens below the sample 32, and the convergent-beam electron diffraction image is free from the distortion due to the influence of an image forming lens. Thus, a distribution of lattice strains in an electronic device having, e.g., a micronized structure can be displayed in an image with high resolving power and with high accuracy and furthermore in a short period of time.

A rotational angle sensor includes: a magnet rotor in which multiple magnetic poles are formed along the circumferential direction of the magnet rotor; and three sensor devices that are arranged on a circle concentric with the magnet rotor at regular angle intervals. Each of the sensor devices includes three half-bridge circuits each of which has a pair of spin valve magnetic resistances that are connected in series in such a manner that the magnetization directions of spin fixed layers of the spin valve magnetic resistances are opposite to each other. Each of the sensor devices is formed in such a manner that phases of the sensor signals output from the respective half-bridge circuits based on a change in magnetic flux caused by the rotation of the magnet rotor are offset from each other by an electrical angle of 120°.

A display unit that includes an image display part and a light-transmitting protective part arranged on the image display part. A cured resin layer is arranged between the display part and the protective part. The cured resin layer has a transmittance of 90% or higher in the visible range and a storage modulus at 25° C. of 1×107 Pa or less. The cured resin layer is formed from a resin composition that has a cure shrinkage of 5% or less.

A digital electronic stethoscope includes an acoustic sensor assembly that includes a body sensor portion and an ambient sensor portion, the body sensor portion being configured to make acoustically coupled contact with a subject while the ambient sensor portion is configured to face away from the body sensor portion so as to capture environmental noise proximate the body sensor portion; a signal processor and data storage system configured to communicate with the acoustic sensor assembly so as to receive detection signals therefrom, the detection signals including an auscultation signal comprising body target sound and a noise signal; and an output device configured to communicate with the signal processor and data storage system to provide at least one of an output signal or information derived from the output signal. The signal processor and data storage system includes a noise reduction system that removes both stationary noise and non-stationary noise from the detection signal to provide a clean auscultation signal substantially free of distortions. The signal processor and data storage system further includes an auscultation sound classification system configured to receive the clean auscultation signal and provide a classification thereof as at least one of a normal breath sound or an abnormal breath sound.

An image processing apparatus for displaying an input image on a display, includes an image converting unit for converting the input image into an equiaspect ratio image, the equiaspect ratio image having the same aspect ratio as the input image, having one of a horizontal size and a vertical size thereof equal to one of a horizontal size and a vertical size of a display screen of the display, and having an image size thereof being equal to or smaller than the size of the display screen, an additional image generating unit for generating an additional image from the input image, a combination image generating unit for generating a combination image into which the equiaspect ratio image and the additional image are combined, and a display control unit for causing the display to display the combination image.
