Abstract: A retention mechanism is provided for retaining graphics add-in cards in an information handling system. The retention mechanism includes a mount and a retention bracket. The mount is affixed to the information handling system and includes mounting locations. The retention bracket is configured to be affixed to a particular one of the mounting locations and includes an adjustable filler device. The filler device is configured to secure a first graphics add-in card having a first width with the filler device located in a first position, and to secure a second graphics add-in card having a second width that is wider than the first width with the filler device located in a second position.

Abstract: An information handling system uses one connector for both liquid and air cooling and detects the type of cooling system installed. That provides the ability to choose the correct thermal handling table based on the installed cooling system. To detect the type of cooling system installed, a thermal management controller sets a control signal supplied to the cooling system through the connector to a first control value and determines if a tachometer signal supplied by the cooling system to the thermal management controller through the connector indicates a first type of cooling system. If the first type of cooling system is not detected, the thermal management controller checks if the tachometer signal from the cooling system with the control signal set at the first control value, or alternatively at a second control value, indicates a second type of cooling system. If no cooling system is detected, an error condition exists.

Abstract: A method for measuring corneal elastic constant and viscosity constant comprises steps of: ejecting compressed air toward a cornea of a live eye ball and measuring air pressure thereof; emitting infrared rays during an air ejecting period, for measuring corneal deformation caused by the compressed air applied to the cornea; and calculating an elastic constant and a viscosity constant of the cornea based on Kelvin-Voigt model by utilizing the corneal deformation measured via the infrared rays and the measured air pressure during the air ejecting period. One advantage of the present invention is to aid preliminary detection in eye diseases.
