Patent EP-0811965-A2 (EP)
Inventor: VARIAN GEORGE R
IPC: G11B5/53
Filed: 1997-06-03
Abstract: In an azimuth recording format, the crosstalk of the A channel into the B channel is higher than the crosstalk of the B channel into the A channel because, at the ends of a magnetic recording where the switching contour (14e-14g) of constant magnetic field strength is equal to the media magnetization switching field, the switching contour follows a curve (38). The resulting curvature (44,46) at the ends of the magnetic recording vary accordingly the angle of azimuth rejection between the B to A azimuth relative to the A to B azimuth at the edges of the track. The use of a record head (58,90,124) of a unique design wherein the trailing pole face (68,102,130) of the head extends laterally beyond its leading pole face (66,100,132) at the over-writing side of the head, removes the curvature at the ends of the transition recordings (70) forming the recorded tracks. In such record heads, the switching contour generated at the trailing pole face (74,14) of the gap at the over-writing side of the head enters and exits the trailing core generally normal to the pole face and at points thereon which are spaced beyond the corresponding end of the leading core face. Thus, no curvature is generated at the end of the recordings which perform over-writing of the previous adjacent tracks recorded in the media. Thus, the record heads show the same minimized level of crosstalk between the A to B or the B to A azimuth channels.

Abstract: A ferroelectric liquid crystal device, such as a display panel, has a plurality
of pixels arranged as rows and columns in a passive matrix arrangement.
Each pixel has a plurality of switching thresholds, for instance by having
different regions (7, 8) of different thicknesses, so as to provide a plurality
of grey levels. A voltage waveform is applied to each pixel for switching it
to a desired grey level. A blanking pulse of a first polarity is applied to
reset the pixel to a reset grey level. This is followed by a compensating
pulse (20) of polarity opposite the first polarity, after which a waveform for
selecting the desired grey level is provided. The effect of the
compensating pulse (20) is to reduce the effect of τmin shift so as to
provide a relatively wide driving window (13) to allow more reliable
selection of an intermediate grey level.

Abstract: The knee protection device has a protection part and two side connecting straps that are holding sections (20,30) for fixing the protection to the knee. Both of the holding sections are built with regard to the orientation and cross-section of the knee and impact pressure to the wall muscle (W). The anatomical change of the pressure surface of the wall muscle between the kneel position and stand position stays essentially even and spread over the pressure surface. In both holding sections, a torsion band can be seen. The moving of the upper surface of the wall muscle when changing between kneeling and standing can be ineffective but the opposite movement can create a torsion through the length axis.

Abstract: A composite thermal interface pad (74) is comprised of a template portion (76) formed
from a material such as thermal gap pad material or thermal tape, in which cavities have been
formed and filled with a pliable non-resilient material, such as thermal grease or thermal putty.
The spacing and size of the cavities may be tailored to achieve desired elastic properties and
stress distributions, as well as optimise the thermal characteristics of the thermal interface with
respect to heat distribution patterns of electronic components (66-72) being cooled. The
composite thermal interface pad may also be used to provide EMI shielding along the gap
formed between the electronic component and the adjacent cooling structure by filling closely
adjacent cavities with electrically conductive non-resilient material. In one embodiment. an
adjacent structure is provided with projection features that dig into the non-resilient material,
thereby ensuring a good thermal interface, increasing the surface area available for thermal
transfer, and minimising the distance between the electronic component and the adjacent
structure used for cooling.

Abstract: An electrical connector (e.g., a plug or receptacle for a plug) has
multiple conductors that carry two or more transmission paths, where each
transmission path uses (at least) two conductors to carry a balanced signal. A portion
of the like conductors of one type are grouped together and separated from a portion
of like conductors of another type. For example, in one embodiment, the electrical
connector is a plug having contacts used to terminate a multi-wire cable carrying up to
four voice or data signal transmission paths and having four pairs of TIP-RING
contacts, where a portion of the four TIP contacts are grouped together and a portion
of the four RING contacts are grouped together and separated from the group of TIP
contacts. In this way, electromagnetic (e.g., capacitive and/or inductive) coupling
between like conductors (e.g., from TIP contact to TIP contact) will be generated that
opposes electromagnetic coupling between unlike conductors (e.g., from TIP contact
to RING contact) which may otherwise result in unacceptable levels of crosstalk
between transmission paths in the electrical connector.
