Power and multimedia center device

There is provided a chuck that includes a supporting element that is connected to a closing element. An upper surface of the supporting element includes a chemically etched zone and an un-etched zone. The chemically etched zone includes multiple upper areas that are surrounded by trenches. At least one pressurized gas conduit is formed in the supporting element so as to enable pressurized gas provided to a lower surface of the supporting element to propagate through the trenches. The un-etched zone is shaped in response to a shape of an object to be placed on the supporting element. The un-etched zone reduces pressurized gas leakage from the un-etched zone and the closing element reduces pressurized gas leakage from a lower surface of the supporting element when the object is placed on the chuck in alignment with the un-etched zone and pressurized gas is provided to the chuck.

Chuck and a method for supporting an object

A system includes a first supporting element, a first supporting element rotation module, a controller and a first optical head. The controller is configured to control a rotation of the first supporting element by the first supporting element rotation module. The first supporting element is coupled to the first optical head. The first supporting element rotation module is configured to rotate the first supporting element until text that is imprinted on a first side of a semiconductor wafer is located within a field of view of the first optical head. Semiconductors wafers of different size have text located at different locations. A method for obtaining a text imprinted on a first side of a semiconductor wafer, the method includes: determining a location of the text based on a size of the semiconductor wafer; rotating a first supporting element that is coupled to a first optical head until the text is located within a field of view of the first optical head; obtaining an image of the text by the first optical head; and translating the image of the text into text.

System and method for obtaining text

An optical communication link coupling a rotating part of a gantry of a computerized tomographic scanner to the stationary part of the gantry. The link comprises an arcuate hollow light conductor having one part rotating with the rotor of the gantry and the other part fixed to the stator of the gantry. Signal bearing light beams are transmitted into the link and are subsequently received from the link after transversing at least a portion theroef.
