Patent number: 7651925Abstract: A frame and vacuum expansion chuck are used in combination for stretching a tape carrying a plurality of singulated devices to facilitate removal of the devices with reduced risk of contact between a device being removed from the tape and an adjacent device on the tape. The combination includes a frame for holding edges of a tape carrying a plurality of singulated devices, and a vacuum chuck having upper surfaces for contacting an underside of a tape carrying a plurality of singulated devices. The vacuum chuck extends along a perimeter circumscribing the singulated devices, and at least one groove is defined in the upper surface of the vacuum chuck. Conduit for providing fluid communication between the groove and a vacuum source are provided. Upon evacuation of the volume defined between the groove and the tape, the tape is drawn down into the groove and stretched, thereby increasing the separation or gap between adjacent dice and reducing the risk of damage upon removal of the dice.Type: GrantFiled: March 1, 2007Date of Patent: January 26, 2010Assignee: Delphi Technologies, Inc.Inventor: M.

Patent number: 7620216Abstract: A human eye is tracked between successively produced video image frames by consecutively applied eye location techniques. First, potential eye candidates within a local search window are identified using horizontal projection filtering, coupled with rudimentary appearance-based testing. The identified eye candidates are clustered and subjected to additional appearance-based testing to determine if one or more eye candidates should be accepted. If no eye candidates are accepted, a correlation/appearance technique is applied to the search window to identify the eye. If unsuccessful, the eye may be closed, and peripheral eye-related patches from the previous image frame are extracted and compared with the search window to identify the eye in the current frame. When comparable eye-related patches are identified in the search window for the current frame, the eye center is computed according to the mean of the eye periphery patches.Type: GrantFiled: June 14, 2006Date of Patent: November 17, 2009Assignee: Delphi Technologies, Inc.Inventor: Riad I.
