The present disclosure relates to a work safety management system using a safety belt unit for high-place work, and safety during working at a high place can be enhanced by determining whether a worker has fastened a seat belt to a safety structure, and the location of the worker, whether the seat belt is fastened and whether the work is on progress can be monitored in real time from a remote location to prevent safety accidents.

An attachment device to an anchor point comprises a wire-like element provided with two ends a first end of which has a first ring. A clamp has two ends a first end of which can be inserted in the first ring. The second clamp end presents a second cross-section larger than the first cross-section. The first clamp end defines a through hole receiving a rope supporting a user. The second end of the wire-like element is fixed to the clamp via a first attachment point between the through hole and the second clamp end. A cord has a first end fixed to the clamp via a second attachment point and a second end with a second ring.

An endoscope having an insertion portion to be inserted into an object to be observed, includes: a substantially tubular holder member mounted to the insertion portion and having an open front end portion including a shoulder surface surrounded by an axial wall; a lens barrel holding an objective lens system and received in the holder member; and a light-transmissive closure member fitted into a front opening defined by the axial wall, and fixed to the front opening by a bonding agent interposed between an outer circumferential surface of the closure member and an opposing inner circumferential surface of the open front end portion of the holder member, wherein a space axially adjoining the shoulder surface is defined between an outer circumferential surface of a front end portion of the lens barrel and an opposing inner circumferential surface of the holder member.

A method, system and program product are provided for planning an intervention procedure in a body lumen. A CT scan of the body lumen is performed. A virtual rendering is created of the inside of the body lumen corresponding to an interventional camera image. Then a virtual tape corresponding to a planned path for the intervention procedure is projected onto a wall of the body lumen. The virtual tape is projected onto the lumen wall, which is relatively distant from the camera point on the virtual rendering, so the tape does not appear to oscillate like a central thread. Also, since the virtual tape is located on the lumen wall, it does not occlude the center of the lumen, allowing a user to better visualize the lumen during planning, during fly through, and even during an actual intervention.

An image sensor includes: photoelectric conversion elements configured to receive light and accumulate a charge corresponding to an amount of received light; an imaging signal generating unit that converts the charge accumulated in each photoelectric conversion element into a voltage to generate an imaging signal; and a reference signal generating unit that generates a reference signal having a fluctuation component with a same phase as the imaging signal. The imaging signal generating unit includes: a conversion circuit that converts the charge accumulated in each photoelectric conversion element into the imaging signal; a noise eliminating circuit that eliminates a noise component included in the imaging signal; and an output circuit that outputs the imaging signal from the conversion circuit. The reference signal generating unit includes a circuit having a same structure as that of at least one of the conversion circuit, the noise eliminating circuit, and the output circuit.

A stereo comparator configured for use with a stereo endoscope for adjusting and aligning an optical assembly of the stereo endoscope, for example, in connection with the repair of the endoscope. The comparator includes a housing containing a plurality of optical components, namely, a first deflecting component, a second deflecting component, a third deflecting component and a beam splitter. The optical components are arranged so that the first deflecting component deflects a first beam from a right image channel of a stereo endoscope to the beam splitter, the second deflecting component deflects a second beam from a left image channel of the stereo endoscope to the third deflecting component, the third deflecting component deflects the second beam to the beam splitter and the beam splitter combines the first beam with the second beam to form a first combined beam that extends along an optical axis of the stereo endoscope.

An image processing apparatus according to the present disclosure includes an illuminating section which sequentially irradiates an object with first and second illuminating light beams polarized in first and second directions. First and second polarization images are generated based on signals representing light transmitted through polarizers having the polarization transmission axis in respective directions that are parallel to, and intersect with, the first direction while the object is being irradiated with the first illuminating light beam, and third and fourth polarization images are generated based on signals representing light transmitted through polarizers having the polarization transmission axis in respective directions that are parallel to, and intersect with, the second direction while the object is being irradiated with the second illuminating light beam. A depressed object surface region is detected based on the first and second polarization images and/or the third and fourth polarization images.

Certain configurations are described of methods and systems that can be used to image three-dimensional objects such as biological cells, biological tissues or biological organisms. The methods and systems can image the three-dimensional objects at reduced imaging times and with reduced data volumes.

A medical observation apparatus includes: a display unit that displays thereon an observation image corresponding to a result of examination on a subject; a first camera that performs imaging of plural persons surrounding the subject, and outputs a surrounding image; a selecting unit that selects, based on the surrounding image, an indicator from the plural persons; a line of sight detecting unit that detects a line of sight of the indicator; and a display control unit that causes the display unit to display thereon a superimposed image having a pointer superimposed on the observation image, the pointer being at a position according to a destination of the line of sight of the indicator.
