Title: Linear pulse-width modulation system
Inventor: DWELLEY DAVID M
IPC: H03K7/08
Filed: 2001-03-08
Abstract: A linear pulse-width modulation system provides a pulse-width modulated (PWM) signal which varies linearly with a control voltage over a full range of duty cycles. The pulse width modulation system has a plurality of comparator 74, each having one input coupled to a control voltage Vc and a second input coupled to a periodic waveform signal provide by a waveform generator 72. The periodic waveform signals are identical except that each waveform is time delayed with respect to the adjacent waveform signal. The outputs of the comparators 74 are coupled to a multiplexer 78 which selects the output of each comparator 74 as the PWM signal 79 for a time interval corresponding to when the output signal of the comparator has substantially constant propagation delays. The propagation delays in a comparator's output signal are substantially constant when the periodic waveform signal input of the comparator is not near its minimum or maximum voltage.

Title: Detecting buried geotextile
Inventor: JAY ANTHONY
IPC: G01V15/00
Filed: 2001-07-31
Abstract: A geotextile structure 1 is buried between a subgrade layer 5 and a ballast layer 6 of a railway track 7 and incorporates metallic stripes 33 with well-defined edges which respond to ground-probing radar or other electromagnetic survey techniques to enable the presence of the stripes to be remotely detected from the surface. This enables the radar velocity through the ballast layer to be calculated rather than estimated and thus the depth of burial of the geotextile structure may also be accurately calculated rather than estimated from an assumed radar velocity value. Other embodiments in which the pattern of the metallic stripes encodes information e.g. relating to the geotextile (figure 8) and in which the geotextile may be laid over or wrapped around an underground feature such as a pipe or cable to facilitate remote location and/or identification of the feature (figures 9 and 10) are also disclosed.

Patent GB-2374732-A (GB)
Title: An electrical machine with laminated cooling rings for end turns
Inventor: LIANG FEN
IPC: H02K9/22
Filed: 2001-12-14
Abstract: An electrical machine, such as a starter-alternator, has a housing 24, a rotor 12, and a stator core 14 with first and second ends 16, 18 and windings therein. End turns 20, 22 of the windings protrude from the first and second ends of the stator core 14. First and second laminated aluminium ring assemblies 32, 34 are positioned against the first and second ends 16, 18 of the stator core 14, in contact with the housing 24. Thermally conductive potting material 30 is positioned between the end turns and the ring assemblies 32, 34 at each end of the stator core 14, thereby creating heat dissipation paths from the end turns 16, 18, through the potting material 30 and the ring assemblies 32, 43 to the housing 24. The total thermal resistance is much lower than that of the existing potting technology, and a flexible potting material can be used. Motor efficiency is improved due to lower copper losses in the lower temperature winding. The laminations 36 in the laminated aluminium ring assemblies 32, 34 are insulated to reduce eddy current losses, and in addition, each lamination 36 has a plurality of radial slots 38 further to reduce eddy current losses. The invention can also be used in traction motors for fuel cell electric vehicle (EV), pure EV and hybrid EV applications.

Title: A suspension system for vehicles
Inventor: ROBINSON EDWIN
IPC: B60G17/056
Filed: 2002-05-23
Abstract: A suspension arrangement for the axle/wheels of vehicles comprising links 1 and 2 rotatably attached to the chassis or body at one end 3 and 4 and similarly by connections 5 and 6 to link 7 which supports the wheel axle 8 at its opposite end. The layout and proportions thereof, result in a geometry, which imparts substantially rectilinear motion to the axles/wheels. Furthermore the limited angular displacement of the axle support link 7 is such that centre lines projected from the axle 8 in any position on locus 9 and equidistant between the pivotal connections 5 and 6, when extended intersect at a point 10, which exhibits relatively short rectilinear motion, designated by the letter 'A', at ninety degrees to that of the wheel. Additionally the velocity of this latter motion is a fraction of that experienced by the wheel/axle and varies from a maximum at the extremity of movement to zero at mid position. The arrangement includes provision to incorporate additional links (13, Fig 3) torsion bars (28 and 29, Fig 6) various spring devices (16, Fig 3 and Fig 7) and dampers (32, Fig 7) to control wheel motion in the desired manner. Braking systems (11, Fig 5) can be easily incorporated with anti-dive measures, minimising the momentum of the unsprung weight and without compromising the suspension characteristics.

Patent GB-2390948-A (GB)
Title: Autostereoscopic display
Inventor: JONES GRAHAM ROGER
IPC: H04N13/00
Filed: 2002-07-17
Abstract: An autostereoscopic display comprises a pixellated transflective spatial light modulator (22) which is arranged to provide a visual indication to an observer of the amount of crosstalk caused by reflection of ambient illumination. The display comprises a rear parallax barrier (31) between a backlight (13) and the modulator (22). Part of the barrier (31) is formed as a screen (32) blocking transmitted light from a first region (33) of the modulator (22) so that the pixels in this region are visible only by reflection of ambient illumination (35). In a second region (34), the pixels are illuminated with both transmitted and reflected light. A controller (23) sets the pixels of the first region (33) to maximum intensity and the pixels of the second region (34) to a fraction of the maximum intensity. The fraction corresponds, for example, to a maximum amount of crosstalk which is permissible for autostereoscopic viewing. When the brightness of the first region is darker than or the same as the brightness of the second region, crosstalk is sufficiently low to permit autostereoscopic viewing.

Title: Power tool with overload clutch and an arrangement for detecting tool bit blocking
Inventor: STIRM MICHAEL
IPC: F16D43/208
Filed: 2002-09-13
Abstract: A hand held power tool, eg a hammer drill, has an overload clutch 14 in a spindle 40 drive train 14, 5, 10 which transmits rotary drive below a predetermined torque and slips above a predetermined torque. A blocking, eg tool bit jamming, detecting arrangement comprises a sensor 16 in the form of an accelerometer that transmits signals to an electronic evaluation unit 17 which outputs a warning signal when a blocking event is to occur. The signal triggers a circuit 18 which supplies current to an electromagnet 19 which causes the clutch 14 to disengage by retracting actuating shaft 21 thereby allowing locking balls 25 to disengage from pockets 13b. When the actuating shaft 21 is not retracted the locking balls are urged by spring 26 into the pockets 13b and are forced out of the pockets 13b against the action of spring 26 so as to allow the clutch 14 to slip. In other embodiments the electromagnet 19 may be replaced with an inertial mass or a mode change mechanism which disengages the clutch 14.

Title: A method for determining a brake state
Inventor: FRENTZ GEORG
IPC: B60T17/22
Filed: 2003-12-15
Abstract: A method for determining a brake state of a motor vehicle, by means of a temperature sensor arranged in or on a brake lining, the brake state being determined employing a first detected temperature value T(t0), a second detected temperature value T(ti) taken a time duration(ti-t0) after said first temperature valueT(t0), and the said time duration(ti-t0). The brake state determined may be brake lining thickness. Numerous temperature-time values may be taken, including the initial and final temperatures at the temperature sensor to determine the brake state. Other factors which may be included in the determination could be heat generated, consumed kinetic energy, ambient temperature, road moisture, vehicle speed, braking pressure and duration. Depending on the determination, brake-pedal characteristics may be adjusted, or an alarm might be sounded. The measurements can take place at predetermined time points/intervals, when it is safe, and when a useful set of results may be obtained.
