Operation of self-propelled mining equipment in the field can be accurately recognized at a remote position of the equipment. A management center for controlling a dump truck receives signal from sensors in order to show detection data for the working status of the operation instruments and warning indication data based upon the detection data. The warning indication data and the detection data for the working status of the operation instruments are displayed on the same display. Alternatively, in place of the detection data for working status of the operation instruments, related information from a data base concerning the record of maintenance previously conducted may be displayed, or a graph of the detection data for the working status of an operation instrument of another dump truck which is operating in the same working field may be displayed.

Operation management device of self-propelling mining equipment

An identification apparatus keeps the conditions for imaging uniform among successive identifications, and requires a user to perform only a series of simple maneuvers. The apparatus comprises a guide member, a light source, and an imaging unit. The guide member includes a pattern or structure for a user to position his/her finger thereon or to approach his/her specific finger region thereto. A contact member is located in the guide member where a fingertip is positioned. An optical opening is formed at a position coincident with where a finger to be imaged should be placed. The light source radiates near-infrared light through the portion of the finger to be imaged. The imaging means acquires an image of the finger, and the apparatus compares the image to previously registered images. The apparatus may also include dual light sources power saving functionality, and means for limiting the interference of external light sources.

Finger identification apparatus

In a probe device including a light irradiating portion irradiating a light to a surface of a living body, and a light detecting portion detecting the light passing through an inner portion of the living body so as to emit from the surface of the living body, the probe device is provided with a sheet-like probe holding body, a plurality of light emitting probes and a plurality of detection probes which are attached to the probe holding body at a predetermined interval, a board holding portion attached to a predetermined position of the probe holding portion, an electronic board attached to the board holding portion, a sheet holding portion holding the probe holding body at a predetermined position of a head portion (a tested position) of the test subject, and a fixing band portion for installing the sheet holding portion to the test subject.

Probe device

A probe which allows optical fiber fixing tools to be distributed substantially uniformly and symmetrically longitudinally or laterally and is easily fitted, even when a head part size of a subject changes is provided. A plurality of optical fiber fixing tools which fix incident optical fibers and detection optical fibers are arranged on a fixing part in a substantially straight line shape, a plurality of the fixing parts are included, the fixing parts are arranged so that its straight line direction is oriented in a substantially parietal direction, the optical fiber fixing tool on the fixing part and the optical fiber fixing tool on the adjacent different fixing part are connected by a connecting member, and the connecting member is made rotatable around the optical fiber fixing tool, whereby the probe can be fitted so that the optical fibers are arranged substantially symmetrically and uniformly longitudinally or laterally.

Biological optical measurement probe and biological optical measurement instrument therewith

The present invention provides an ultrasonography containing a main body housing having transfer wheels. An operation device having switches, a movable arm to connect the main body housing to the operation device which has an inclined plane inclining rearward from a front face to an upper face; and the movable arm supports the operation device through an elevating function mechanical section to move the operation device.

Ultrasonograph

An ultrasonograph includes a main body to which an ultrasonic probe is connected, an operation device having an operation switch, and a movable arm connecting the main body housing and the operation device. A bumper section is formed around the operation device, and wherein at least one probe container in which the ultrasonic probe is containable is formed at the bumper section.

A probe device for optically measuring a condition of an object includes a light emitter for emitting a light to proceed into the object through a surface of the object, a light sensor for measuring an optical condition of the light proceeding from the surface through the object and subsequently emitted from the surface to reach the light sensor, and a body holding thereon at least one of the light emitter and the light sensor. The body includes at least one main protrusion protruding so as to face to the surface, and at least two sub-protrusions arranged around the at least one main protrusion and protruding so as to face to the surface.

The present invention provides a vertical magnetic field MRI apparatus which is capable of speeding up imaging for taking an image of any cross section of a wide area such as a total body, while suppressing increase of the number of channels and maintaining high sensitivity in a deep portion of a subject. A receiver coil unitincorporates a bed coil unitwhose longitudinal direction agrees with a body axis direction of the test object, and an upper coil unitwhich is detachably mounted on the bed coil unit. The bed coil unitis provided with a carrying surfacefor placing the test objectthereon and multiple lower sub-coils arranged in a lower part of the carrying surface, and the upper coil unitis provided with multiple upper sub-coils which are connected to the lower sub-coils. The upper sub-coils are separated into two parts; one arranged in a flexible inner support-covering the installation surfaceand another arranged in a flexible outer support-covering the external side of the inner support-. The upper sub-coils and the lower sub-coils are connected by mounting the upper coil uniton the bed coil unit, thereby forming the multiple types of sub-coils.

Magnetic resonance imaging apparatus

A probe device includes a sheet-like probe holder, a plurality of light-emitting probes and a plurality of detection probes mounted on the probe holder at a predetermined interval, a sheet holding unit holding the probe holder at a predetermined position on the biological surface, and a fixing band mounting the sheet holding unit on the living body. Each of the plurality of light-emitting probes and the detection probes includes a probe body including a light emitting unit or a detection unit, and a probe mounting part detachably mounting the probe body to the probe holder at a predetermined position.

An identification apparatus that keeps the conditions for imaging uniform among successive identifications and requires a user to perform only a series of simple maneuvers. An identification apparatus comprising a guide member, a light source, and an imaging unit. The guide member includes a pattern or a structure that inspires a user to position his/her finger thereon or to approach his/her specific finger region thereto. A contact member such as a button switch is preferably located at a position in the guide member at which a fingertip is to be positioned. An optical opening is formed at a position coincident with a position at which a portion of a finger to be imaged for identification should be placed. The light source radiates near-infrared light through the portion of the finger to be imaged. The imaging means acquires an image of the finger, and the apparatus compares the image to previously registered images. The apparatus may also include dual light sources power saving functionality, and means for limiting the interference of external light sources.

A motion sensor for measuring motion information of a subject comprises a coil substrate having transmitting or receiving coils piled one on top of another and a holder in which the coil substrate is mounted. Formed on the holder are curved surfaces to which an adhesive sheet is stuck and at which the holder is attached to a nail of a subject via the adhesive sheet. Further, there is provided a casing where first and second containing space are formed to contain measurement instruments including an adhesive member where a plurality of the adhesive sheets are laid one on top of another, the motion sensor, and the like.
