Abstract: An electronic circuit package comprises a carrier (11), a microchip (12), which has bond pads (13) and is attached to the carrier, and a flexible circuit comprising a first flexible circuit element cable (15) attached to the region of the carrier adjacent the microchip and a second flexible circuit element cable (17) attached to and stepped back from the first cable. Each element includes an electrically conductive circuit pattern defined thereon with selected ones of the microchip bond pads (13) being electrically connected by wirebonds (16) to a circuit pattern on the first element of the flexible circuit and further selected ones of the bond pads being electrically connected by wirebonds to the circuit pattern of the second element.

Abstract: A display comprising a cathode ray display tube (1) having an electromagnetic deflection yoke (2) is described. A pair of first deflection coils (7,6) are located symmetrically about the longitudinal axis of the tube (1) on opposite sides of the yoke (2) for producing within the tube (1) a first magnetic deflection field. A pair of second deflection coils (8,20) are similarly located symmetrically about the longitudinal axis on opposite sides of the yoke (2) for producing within the tube (1) a second magnetic deflection field at right angles to the first deflection field. The display is further provided with a pair of first cancellation coils (4,3) connected to the first deflection coils (7,6) for producing a first cancellation field which tends to cancel a first stray field produced by the first deflection coils (7,6). Support means (10,11) secure the first cancellation coils symmetrically about the longitudinal axis. The display additionally comprises a pair of second cancellation coils (50,32) coupled to the second deflection coils (8,20) for producing a second cancellation field which tends to cancel a second stray field produced by the second deflection coils (8,20). Further support means (51,52) are provided for positioning the second cancellation coils (50,32) symmetrically about the longitudinal axis in such a way that a plane containing a second cancellation coil (50) is perpendicular to any plane containing a first cancellation coil (4). Preferably, the display also comprises control means (64) for generating a predetermined cancellation current in the second cancellation coils (50,32) in response to a particular second deflection current in the second deflection coils (8,20).

Abstract: An optical fibre communication link for connecting a peripheral device to a computer system is presented. The communication link includes means for generating a video signal and means for transmitting the signal along an optical fibre between the computer system and the peripheral device. The transmitted video signal includes a reference pulse (1) of predetermined amplitude. Accordingly, there is now provided compensation means (15,16) for correcting changes in the characteristics of a received video signal which result from said optical communication link, and means (17,18) for using said reference pulse in a received video signal in order to control said compensation means. Preferably, the peripheral device is a display device.
