Title: Vibration damping device in a hydraulic circuit operating a clutch
Inventor: OSTERLAENGER JUERGEN
IPC: F16D48/02
Filed: 2000-02-25
Abstract: A damping device is connected in a pressure line between a clutch slave cylinder and a clutch master cylinder and comprises a single or two piece housing 1a containing a sealed piston 13 biassed by a coil or plate spring 12. Vibrations transmitted from an internal combustion engine to the hydraulic circuit are damped by the piston 13 moving against the spring 12 so as to expand the volume in the housing 1a. The plate springs 12 may be arranged in alternate directions and/or the same direction so as to influence the damping characteristics of the device. In the two piece housing there is a socket part (22a, fig 2), which may contain a throttle valve, and a push-in part (23a) that engage with each other by means of a keyed connection held together by a sleeve (24a). The piston in the one piece housing 1a is contained in a section that is off-set relative to an inlet and outlet. Many other embodiments are disclosed including damping devices that use membranes that flex to accommodate the vibrations.

Title: Improved liquid crystal display device
Inventor: DOE STEVEN CHARLES
IPC: G09G3/36
Filed: 2001-01-31
Abstract: A reflective liquid crystal colour display device for use in portable electronic apparatus such as mobile phones, uses processing circuitry to receive image data in the form of a digital data file such as a JPEG or MPEG etc. The processing circuitry performs digital filtering of the image data so that relatively dark regions are displayed lighter than indicated by the image data. This process compensates for image darkening produced by the display device without the use of a separately energisable illumination source. The processing circuitry can filter the image data according to the level of ambient light detected by a photodetector attached to the device.
