Patent number: 6292919Abstract: The present invention, in one form, is a communication system for transmitting high-speed data across an imaging system slip-ring. In one embodiment, the communication system includes a transmitter and a receiver. The transmitter generates encoded serial data that is transmitted across the slip-ring 1 bit at a time to the receiver. The encoded data includes command codes, message blocks having CRC data, and SYNC data. Using the commands codes, the receiver decodes the data into byte data. The receiver utilizes the CRC data to detect and correct errors in the transmitted data and the SYNC data to synchronize the receiver with the transmitter.Type: GrantFiled: August 25, 1998Date of Patent: September 18, 2001Assignee: General Electric CompanyInventors: Mark David Fries, Phil E.

Patent number: 4839805Abstract: Dual control of image level and window of a display is accomplished by rotation of a single trackball. Rotation of the trackball within a first band including the X axis controls one parameter, and rotation of the trackball in a second band including the Y axis controls a second parameter. No changes are made in the parameters in response to rotation of the trackball in a third deadband laying between the first band and second band. The operator of a tomography system can readily change display parameters by rotation of the trackball while viewing the display.Type: GrantFiled: November 17, 1983Date of Patent: June 13, 1989Assignee: General Electric CompanyInventors: Phil E.

Patent number: 4611348Abstract: A set of two processors operates on image pixel data using polynomial interpolation to generate pixel data for a spatially varied image. Image data is first stored in a buffer memory, and constants used in the polynomial interpolation are stored in a constants memory. One processor operates on the data from the buffer memory using constants from the constants memory, and the interpolated data is then stored in a display memory. The second processor controls the interpolation process by addressing the memories for the retrieval and storage of data.Type: GrantFiled: November 26, 1984Date of Patent: September 9, 1986Assignee: General Electric CompanyInventors: Eugene C.
