  • Patent number: 11973979
    Abstract: A method of displaying images forming part of a digital reality stream, the method including, for each image to be displayed in one or more encoder processing devices, generating compressed image data by differentially compressing image data indicative of the image in accordance with system operation and the content of the digital reality stream so that different parts of the image are compressed using a different degree of compression, wirelessly transmitting the compressed image data to a display device using a wireless communications link, and, in one or more decoder processing devices associated with the display device, differentially decompressing the compressed image data to thereby generate image data indicative of the image to be displayed.

  • Patent number: 10689001
    Abstract: A method of controlling a dual clutch transmission power on up shift including an on-coming clutch and an off-going clutch. The method includes implementing a prep phase comprised of decreasing torque on the off-going clutch, monitoring the off-going clutch speed to determine a slip point, and adding a bump torque to the off-going clutch when the off-going clutch reaches the slip point. The method implements a torque phase transferring torque from the off-going clutch to the on-coming clutch by increasing torque on the on-coming clutch towards an engine torque, decreasing torque on the off-going clutch, and simultaneously keeping the combination of torques greater than the slip point.

  • Patent number: 8672803
    Abstract: An automated manual transmission system (1) including an input shaft (4), a clutch, an output shaft (6), and a gearbox enabling selection of different transmission ratios between the input shaft and the output shaft (6). An actuation mechanism (10) is operatively connected to the clutch and the gearbox to effect disengagement and re-engagement of the clutch and coordinated selection of the transmission ratios. A hybrid motor (14) is operably connected to the output shaft (6) and a control system (16) is operable to regulate the actuating mechanism in response to control inputs, to effect automatic gear changes. The hybrid motor (14) is responsive to the control system (16) to provide supplementary torque to the vehicle driveline when the clutch is disengaged, to reduce torque interruption in the driveline.

  • Publication number: 20110239859
    Abstract: A piston arrangement includes, but is not limited to a hydraulically-actuated piston to move a piston rod within a cylinder to pivot a clutch actuating lever, the end of the cylinder being sealed by a boot-type seal having a central hole, though which the rod slides in a reciprocating manner. The seal is flexible to permit transverse movements of the piston rod and has a peripheral flange by means of which it is attached to the cylinder end.
