Title: Inductive position detector including a train of magnetic balls
Inventor: HUDMAN FREDERICK MARK
IPC: G01D5/20
Filed: 2002-09-02
Abstract: An inductive position detector 10 comprises a longitudinally extending scale 20 and a transducer 30 movable along the scale. The scale 20 comprises a tube 21 of non-magnetic material housing a train of magnetic balls 22. The transducer surrounds the tube 21 and comprises transmission and pick up coils.

Title: Matchline sense circuit and method
Inventor: MA STANLEY JEH-CHUN
IPC: G11C15/04
Filed: 2001-05-01
Abstract: A matchline sense circuit for detecting a rising voltage on a matchline of a CAM array is disclosed, the circuit initially precharges a matchline to ground before turning on a current source to supply current to the matchline and raise the voltage of the matchline. A reference matchline sense circuit generates a self-timed control signal to keep the current supply turned on for a predetermined duration of time. Sensed data on the matchlines are latched after the current source is turned off and the matchlines are precharged to ground. Because the matchline sense circuit of the present invention precharges the matchlines to ground instead of the supply voltage, VDD, less power is consumed. By sensing the rise of the matchline voltage to an n-channel transistor threshold potential, the matchline sensing operation speed is increased.

Title: Steering lock for a bicycle
Inventor: HEWITT PAUL RAYMOND
IPC: B62H5/06
Filed: 2002-11-04
Abstract: A steering lock which is located in the headstem of a bicycle. Use of the lock allows the steering of the bicycle to be disengaged and, thereby, acts as a deterrent to theft. A bush 3, to which is attached the mount 15 for the handlebars, is rotatable around the longitudinal axis of the support tube 2 which contains the lock mechanism. Turning a key 6 in the lock rotates a cam 8. As the cam rotates, it moves two or more rolling bodies 14, positioned equiangularly within the lock mechanism, into corresponding grooves on the interior surface of the bush 3. When the rolling bodies are located in the grooves, the steering would be locked in an operable state. When the rolling bodies are not located in the grooves, the bush would be free to rotate around the steering support post, rendering the bicycle unsteerable.

Title: Apparatus and method for investigating semiconductor wafers
Inventor: WILBY ROBERT JOHN
IPC: G01R31/26
Filed: 2001-06-29
Abstract: In order to determine the dielectric constant of a layer deposited on a semiconductor wafer (2), the density of the layer is obtained. To obtain that density, the wafer (2) without the layer is weighed in a weighing chamber (4) in which a weighing pan (7) supports the wafer on a weighing balance. The weight of the wafer is determined taking into account the buoyancy exerted by the air on the wafer (2). Then the layer is deposited on the wafer (2) and the weighing operation repeated. Alternatively a reference wafer may be used. If the material of the layer is known, the weight of the layer can be used to derive its density using a thickness measurement. Alternatively, if the density is known, the thickness can be obtained.

Patent GB-2402830-A (GB)
Title: Colour coding of data dependant on human perception of colour
Inventor: DONNELLY NICHOLAS
IPC: G01J3/46
Filed: 2003-06-12
Abstract: A method for colour coding of data comprises selecting points in a psychological colour space that represent a range of colours for a colour scale for colour coding of data. Each point selected in the psychological colour space is mapped to a corresponding point in a physical colour space to enable a colour represented by each selected point to be determined, and the determined colours are then arranged into a colour scale. Defining a colour scale with reference to a psychological colour space allows the colour scale to be linear or nonlinear with respect to human colour perception; this can be achieved by using a regularly or irregularly distributed selection of points in a linear or nonlinear psychological colour space. Once data values are assigned to the colours in the colour scale, data arrays can be colour coded according to the scale, and presented to an observer for interpretation. An independent claim is included for a colour scale comprising a plurality of colours wherein the colour values of adjacent colours in the scale are spaced according to the positions of the colours in a psychological colour space.

Title: Temperature-independent low voltage reference circuit
Inventor: FINNEY ADRIAN
IPC: G05F3/24
Filed: 2003-07-31
Abstract: The circuit comprises a first transistor 1 with a threshold voltage Vth having a negative temperature coefficient. A diode 2 having a forward voltage drop with a negative temperature coefficient is coupled with its anode connected to the drain of the first transistor and its cathode connected to the gate of the first transistor. The drain of the first transistor 1 provides a voltage with a negative temperature coefficient equal to the sum of the forward voltage drop across the diode 2 and the threshold voltage of the first transistor. A circuit 7-10 providing a voltage with a positive temperature coefficient is coupled between the drain of the first transistor 1 and the low voltage supply terminal and has an output terminal. The positive temperature coefficient balances said negative temperature coefficient so that the voltage at said output has a temperature coefficient of zero. Transistors 7, 9 form a current mirror. The circuit is constructed using FETs, avoiding the use of bipolar transistors.

Title: A clutch friction plate assembly
Inventor: AMOS DARYL KEITH
IPC: F16F15/123
Filed: 2004-05-01
Abstract: A clutch friction plate assembly (1) comprises a hub (7a, 7b) with a friction plate (2) coaxially mounted on the hub (7a, 7b) such tat rotation of friction plate (2) relative to the hub (7a, 7b) is possible. Acting between the friction plate (2) and hub (7a, 7b) is a relatively high stiffness spring to absorb high torque pulses applied between the friction plate (2) and hub (7a, 7b). Low stiffness springs are arranged to act between the friction plate (2) and the hub (7a, 7b). This in combination with the inertia associated with the input shaft of the gear box provides a mass spring system which can have a sufficiently small resonant frequency so that compression torque pulse associated with the engine at idle can be absorbed, reducing gearbox rattle.
