Patent BR-9917532-A (BR)
Inventor: BARRE BERTRAND
IPC: B25B7/00
Filed: 1999-10-26
Abstract: A peg has a one-piece clip essentially consisting of two branches, each branch having an anterior part forming a jaw and a posterior part forming a lever arm. The peg also has a hinge around a rotational axis that connects the branches at an intermediate point. A spring extending along a direction substantially perpendicular to the rotational axis is mounted and compressed between the two lever-forming parts of the two branches. The spring urges, under its biasing resilience, the two branches to a closed position. The spring has a biasing force in the direction of increasing its axial longitudinal dimension that is more controllable over time than a spring having a biasing torque. Thus, over time the pressure exerted by the arms of the peg in the closed position remains more constant.

Title: Acquisition of colour components of an image during scanning
Inventor: KEITHLEY DOUGLAS G
IPC: H04N1/48
Filed: 2000-11-07
Abstract: Control of the acquisition of colour components of pixels in a scanning system is achieved by an interface circuit (<B>113a</B>) having a multiplexer (<B>203</B>) to route a signal representing at least one of the colour components from a sensor (<B>116a, 116b</B>) to a register (<B>206</B>). Alternatively (see <B>fig. 9</B>), three registers (<B>403, 406, 409</B>) receive a signal representative of a colour component from a sensor (<B>116a, 116b</B>), where at least one of the colour components is acquired by a multiplexer (<B>423</B>) having a number of inputs. For both alternatives, logic controls the capture of various colour components according to random patterns (one independent claim describes simultaneous capture of all components) and/or only a reduced number of the total components are captured. A reduced number reduces the scan time of a document, while the random pattern eliminates the problem of colour artifact.

Title: Method and apparatus for improving the efficiency of an induction motor
Inventor: BRANECKY BRIAN THOMAS
IPC: H02P23/08
Filed: 2000-12-11
Abstract: An apparatus and method of maximising the efficiency of an induction motor 10 is provided. Three phase AC power is supplied to energise the motor 10. An analogue DC voltage 108 and an analogue DC current 112 are measured and used to determine an estimated phase voltage 128. An actual torque producing current 158 is determined based on the DC voltage 108, DC current 112 and the estimated phase voltage 128. An estimating torque producing current value 160 is determined and compared with the actual torque producing current value 158. An error term 170 representing the difference between the actual and estimated torque producing current values 158, 160 is determined. The estimated phase voltage value 128 is changed based on the error term 170. The three phase AC power supplied to the motor is adjusted based on the estimated phase voltage 128. An analogue to digital converter may be used to convert the analogue DC voltage and current to digital signals. A microprocessor may be used to determine the actual torque producing current and the error term. In a further embodiment, a circuit to estimate the predetermined slip of the motor is disclosed.

Title: Method of changing the dynamic range of an image by contrast mapping
Inventor: SOBOL ROBERT E
IPC: G06T5/00
Filed: 2001-01-15
Abstract: A method of changing the dynamic range of an original image to more closely match th range of the medium used of reproduction which limits maximum contrast differences between areas of an image while preserving small contrast differences between different areas. A look up table may be used to preserve small differences and limit the maximum differences. Preferably the maximum contrast difference is limited to a ratio of four to one or less and the small contrast differences are enhanced using a slope of one to one. Also described is a method of improving apparatus that sequential determines a comparative measure of radiance information, wherein an intermediate value of the radiance information is determined in response to the product of two ratio functions of the radiance information of selected areas, a new value of the measure is determined by selectively weighting the intermediate value and small contrast differences of the ratio function are preserved and the maximum contrast differences of the ratio function is limited.

Title: Double-lift exhaust pulse boosted i.c. engine compression braking method
Inventor: FALETTI JAMES J
IPC: F02D13/04
Filed: 2001-02-02
Abstract: A method of compression braking is provided for use in an internal combustion engine, eg a six-cylinder engine, having a plurality of combustion chambers that share a common exhaust manifold. The method involves opening each exhaust valve twice during each four-stroke cycle, firstly at about the beginning of the power stroke of the associated cylinder and secondly at around the end of the intake stroke. The first opening event may last for 80 degrees after TDC and the second opening event may extend from 120 degrees after BDC until 30 degrees after TDC. In a six-cylinder engine, a first opening event of one cylinder will coincide with a second opening event of another cylinder; as a result, the pressure in the cylinder undergoing the second opening event will increase as a result of the pressure pulse provided by the other cylinder of such a pair undergoing the first opening event.
