One example of an inspection system includes a laser, a magnification changer, and a first camera. The laser projects a line onto a wafer to be inspected. The magnification changer includes a plurality of selectable lenses of different magnification. The first camera images the line projected onto the wafer and outputs three-dimensional line data indicating the height of features of the wafer. Each lens of the magnification changer provides the same nominal focal plane position of the first camera with respect to the wafer.

Systems and methods provide for detection and controlled interaction with one or more objects. The system can include an imaging subsystem (20), a tool subsystem (26) containing one or more tools, a stage subsystem (16) and a control system (40). The control system (40) can integrate controls for each of the other subsystems, which controls can be implement desired functions over a variety of process parameters to perform the controlled interaction.

A system and method for estimating aspects of target objects and/or associated task implementations is disclosed.

Disclosed herein are an apparatus and method for measuring a volume of an object. The object volume measuring apparatus includes an area measuring unit that includes a detection sensor, which is arranged at predetermined spacing in a single row along lengthwise edges and widthwise edges of a plate respectively, where an object is placed, measures a length and a width according to the numbers of detection sensors lengthwise and widthwise respectively in which the edges are detected, and calculates an area of the object according to the measured length and width, a height measuring unit that is located above the plate and comprises a distance measuring sensor for measuring a height of the object when the object is placed, and an object calculation unit for calculating a volume of the object based on the area and the height.

Provided are a liquid surface inspection device, an automated analysis device, and a liquid surface inspection method with which instances of contamination can be minimized and the accuracy of the manner in which the surface conditions, such as bubbles or the like, of a liquid substance are detected can be enhanced. The device has: a light illumination unit for illuminating a container holding a liquid substance, as well as the surface of the liquid substance, with light; an image capture unit for acquiring a video image having at least color information and brightness information of light from the container and the liquid substance which are illuminated by the light illumination unit; and a detection unit for using the color information and brightness information in the video image captured by the image capture unit to detect the condition of the liquid surface.

The optical measurement apparatus includes an interface unit and a measuring unit. The interface unit is configured to receive a synchronization signal transmitted from a PLC to a fieldbus at a constant communication cycle, and output, in synchronization with the synchronization signal, a result of measurement (a measured value) by the optical measurement apparatus and a synchronization supervisory signal. The measuring unit is configured to execute optical measurement at a measurement cycle irrelevant to the communication cycle and generate a result of the measurement and a synchronization supervisory signal. The measuring unit sets the synchronization supervisory signal into an ON state in synchronization with receipt of the synchronization signal by the interface unit after start of the measurement, and sets the synchronization supervisory signal into an OFF state in synchronization with receipt of the synchronization signal by the interface unit when the interface unit outputs the measurement result.

An apparatus having a layer of fats, oils and grease (F.O.G) on water includes a tank having an inlet and an outlet. The inlet connects to a source of F.O.G.-laden effluent and the outlet connects to a sewer pipe so that the outlet defines a normal static water level for F.O.G. and effluent in the tank. A sensor mounted above the static water level determines a distance from the sensor to a top of F.O.G. within the tank, so that a thickness of the F.O.G. in the tank can be determined. If the sensor is LIDAR, sensing may be at about 940 nm. When the F.O.G. is sensed to be above a threshold, the apparatus generates signals to remove the F.O.G. Ultrasonic sensing may be used. Preferably, the sensor is mounted far enough above the static water level so the distance between the sensor and the liquid surface is filled with air. More preferably, the sensor is far enough above the static water level so that the top of the F.O.G. does not touch the sensor even as the top of the F.O.G. rises above the static water level.

Tissue sample cassettes for receiving tissue samples include an upper tray including compartments separated by dividers, a lower tray coupled to the upper tray and having a central recess, and an absorbent material located in the recess of the lower tray. Related systems and methods for automated gross processing of tissue samples are also disclosed.

A parts supply device includes a stage having a placement surface on which a plurality of parts is placed, an imaging system configured to image the plurality of parts from an obliquely upward direction with respect to the placement surface of the stage, and a parts detection unit configured to detect positions and orientations of the plurality of parts on the placement surface of the stage based on image information obtained by the imaging system.

An intraoral scanner comprises a light source, a moveable opto-mechanical module, an axial actuator, and an image sensor. The light source is configured to generate light that is to be output onto an object external to the intraoral scanner. The moveable opto-mechanical module comprises integrated projection/imaging optics and an exit pupil, the projection/imaging optics having an optical axis, wherein the projection/imaging optics are entirely integrated into the moveable opto-mechanical module. The axial actuator is coupled to the projection/imaging optics and configured to move the moveable opto-mechanical module comprising an entirety of the projection/imaging optics in the optical axis to achieve a plurality of focus settings. The image sensor is configured to receive reflected light that has been reflected off of the object external to the intraoral scanner for the plurality of focus settings.
