The invention relates to an interface for connecting an optical device and a mobile support which cooperates securely with an imprinted element, the interface having a base arranged to be inserted into the imprinted element, the base being a hollow body. The base accommodates mechanical play compensating structures which are movably mounted within the hollow body so as to project and are arranged in order to bear against a wall of the imprinted element.

A surveying apparatus has a combined structure of a total station and a laser scanner. The surveying apparatus includes a point cloud data acquiring unit, an abnormal part detecting unit, an abnormal part position acquiring unit, and an automatic sighting controller. The point cloud data acquiring unit acquires first point cloud data and second point cloud data obtained by laser scanning that is performed on an object to be inspected at a time interval. The abnormal part detecting unit calculates a difference between the first and second point cloud data to detect a part of the object to be inspected, at which position information varies, as a detailed-inspection target part. The abnormal part position acquiring unit acquires a position of the detailed-inspection target part. The automatic sighting controller controls to make the total station sight the detailed-inspection target part, based on the position of the detailed-inspection target part.

Performance of enhanced visually directed procedures under low ambient lighting conditions. A computer readable medium storing a set of computer instructions for performing an enhanced visually directed procedure under low ambient visible light on a patient's eye. The computer instructions include: acquiring at least one real-time high resolution video signal representing at least one view of the eye in at least one wavelength of light outside of the wavelengths of visible light. The computer instructions include converting the at least one view is converted corresponding to the at least one real-time high resolution video signal at the at least one wavelength of light outside of the wavelengths of visible light into at least one wavelength of visible light. The at least one high resolution photosensor is acquired after light conditions are low enough such that a pupil of the eye does not constrict substantially from its maximum pupillary diameter.

An optical device includes an underlying device configured output light in a first spectrum. A stacked device is coupled to the underlying device is configured to be coupled in an overlapping fashion to an optical output of the underlying device. The stacked device is transparent to light in the first spectrum. The stacked device includes electro-optical circuits including: light emitters and detectors. Each detector is associated with one or more light emitters. Each detector is configured to detect light emitted from the underlying device. The light emitters are configured to output light dependent on light detected by an associated detector. Optical filters are optically coupled to an optical input of the underlying device. Each filter is aligned with a detector to suppress absorption of certain wavelengths of light by the underlying device thereby affecting light detected by the detectors and thus further affecting the light output by the light emitters.

The dual tube night vision device comprises a pair of independently pivoting night-vision monoculars connected to a bridge member. Each night-vision monocular is attached to the bridge member by a rotating arm and comprises a pod containing an image intensifier tube. Each arm allows the attached night-vision monocular to move through a rotational travel path, between a stowed position and a deployed position. The dual tube night vision device is configured to detect when the night-vision monoculars are, individually or collectively, moved to a stowed position and then temporarily cut off power to the stowed monocular(s) to increase battery runtime. Power is automatically restored, individually or simultaneously, to the night-vision monoculars when they are rotated back to deployed positions. The dual tube night vision device uses one or more accelerometers to detect when the night-vision monoculars, individually or collectively, are moved to the stowed position and the deployed position.
