Abstract: A fundus camera includes an eyeball-offset detection device and an annular illumination device. The eyeball-offset detection device is configured to detect an offset vector of a lens of the fundus camera relative to an inspected eyeball. The annular illumination device includes a plurality of illumination elements that are arranged in a ring shape around an optical axis of an imaging system of the fundus camera. According to the offset vector of the lens relative to the inspected eyeball, the fundus camera selectively activates one or more illumination elements at corresponding positions to keep an illumination optical path away from a center area of the pupil of the inspected eyeball to reduce effects of corneal reflection and improve illumination quality. Therefore, the abovementioned fundus camera has a large operable range.

Abstract: An insulating glass unit (IGU) assembly line comprising a registration station capable of interleaving double and triple pane IGUs in accordance with an IOU production schedule. Visual indicators or prompts instruct operators at the assembly line in configuring a sequence of IGUs. Triple pane IGUs are assembled with minimal contamination of a center glass lite. A non-contact Bernoulli pad is used to lift a glass lite off from a horizontal or vertical support that conveys it from a glass washer to the registration station. Each of multiple pads has a capacity to lift approximately seven to ten pounds. Use of multiple pads per glass sheet or lite allows lites having dimensions up to 70 by 100 inches (assuming glass thickness of one quarter inch) to be assembled.

Abstract: A slit illumination device includes a first light-emitting element, a first diaphragm and a projection lens group. The first light-emitting element generates a primary illumination light. The first diaphragm has at least one opening and is disposed on a light exit side of the first light-emitting element, wherein the opening is an elongate shaped opening. The projection lens group is disposed on a light exit side of the first diaphragm, converging the primary illumination light and projecting it to a target object. A distance from the first diaphragm to the projection lens group is 1-2 times a focal length of the projection lens group on a light entrance side. The foregoing slit illumination device has advantages of simple structure, small size, and longer depth of field. A microscope system including the foregoing slit illumination device is also disclosed.

Abstract: Method and Apparatus for fabricating a spacer frame for use in an insulating glass unit. One of a multiple number of possible spacer frame materials is chosen for the spacer frame. An elongated strip of the material is moved to a notching station where notches are formed at corner locations. The character of the notches is adjusted based on the selection of the metal strip material and more particularly to achieve bending of the material in an repeatable, straightforward manner. Downstream from the notching station the metal strip is bent into a channel shaped elongated frame member having side walls. Further downstream a leading strip of channel shaped material is severed or separated from succeeding material still passing through the notching and bending station.

Abstract: Method and Apparatus for fabricating a spacer frame for use in an insulating glass unit. One of a multiple number of possible spacer frame materials is chosen for the spacer frame. An elongated strip of the material is moved to a notching station where notches are formed at corner locations. The character of the notches is adjusted based on the selection of the metal strip material and more particularly to achieve bending of the material in a repeatable, straightforward manner. Better control over the notching process is also achieved by exhaust flow control of a double acting cylinder. A positioning spacer achieve very accurate side to side positioning of a die and anvil to precisely notch and deform the metal strip. Downstream from the notching station the metal strip is bent into a channel shaped elongated frame member having side walls. Further downstream a leading strip of channel shaped material is severed or separated from succeeding material still passing through the notching and bending station.
