Abstract
An improved device for supporting and holding an object in place under temperature controlled conditions is described. The device comprises a shaft mounted for rotation about a rotation axis, and a top plate coupled to and rotatable with the shaft. The top plate comprises a top substantially planar surface disposed normally to said axis, a bottom surface disposed opposite the top surface, and at least one aperture disposed in the top surface for providing a negative pressure vacuum so that the object can be held in place on the top surface by the negative pressure vacuum. Electrical temperature sensing means is disposed in the top plate for providing an electrical signal as a function of the temperature of the top plate. Electrical temperature modification means is coupled to and rotatable with the shaft and disposed relative to the bottom surface of the top plate for maintaining the temperature of the top plate at a preselected temperature. Heat sink means is coupled to and rotatable with the shaft and disposed relative to the temperature modification means for drawing excess heat from the temperature modification means away from the top plate. Finally, the table comprises a plurality of electrically-conductive brushes mounted in a spaced-apart relation, and a plurality of electrically-conductive rings concentrically mounted with respect to the axis. Each ring is mounted in a plane normal to the axis and is in electrical contact with and rotatably movable with respect to at least one of the brushes as the table turns about the axis, wherein at least two of the rings are electrically coupled to the electrical temperature sensing means so that the electrical signal can be transmitted from the table, and at least two of the rings are electrically coupled to the electrical temperature modification means so that electrical power can be transmitted to those means.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
