Inventor: DANIELS CHAO F
IPC: F02P3/045
Filed: 2003-10-16
Abstract: The present invention relates to internal engine ignition systems. More particularly, it relates to a method of estimating Minimum Timing for the Best Torque MBT timing using in-cylinder ionization current. The present invention concerns a robust multi-criteria Minimum timing for the Best Torque (MBT) timing estimation method and apparatus utilizing different ionization signal waveforms that are generated under different engine operating conditions. This feature of the present invention determines and combines multiple MBT timing criteria to increase the reliability and robustness of MBT timing estimation based upon spark plug ionization signal waveforms. In a preferred embodiment, the present invention combines MBT timing estimation criteria comprising a maximum flame acceleration location, a 50% burn location, and a second peak location.

Title: Spread spectrum communication system using impulse modulation
Inventor: CONNOR PHILIP JOHN
IPC: H04B1/69
Filed: 2004-03-04
Abstract: The invention is a communication system where information is conveyed by impulse modulation of a propagation medium linking a transmitting entity and a receiving entity. These impulses which are short in the time domain give rise to broadband waves in the frequency domain. These waves propagate from transmitter to receiver through the medium so carrying information. Information is encoded firstly, by grouping together impulses and impressing some pattern upon them to form a "Bit Group" and secondly by then grouping together these Bit Groups to form the larger scale pattern or "Word Group". By this means a single broadband communication channel is converted to a multiplicity of logical channels configurable as a multi-user network. The invention provides means for encryption, transmit power control, spectrum spreading, flow control, multiple antennae, power saving and noise reduction. The invention is not specific to a particular frequency or propagation medium and can be utilised for digital communication in a variety of electronic, acoustic and optical systems.

Title: Automated beer line cleaning
Inventor: MARTIN PHILIP CHRISTOPHE JOHN
IPC: B08B9/032
Filed: 2004-05-22
Abstract: An automated beer line cleaning system provides for the use of a pressure controlled flow of say water, delivered by peristaltic pump 4, to take over the role of the gas source, to force the remaining beverage in the system up to the dispensing tap so that the last amounts in the line can be dispensed instead of wasted. The pressure is controlled by pressure regulator 9 and pressure sensor 7. Once the lien is filled with water, on activation of a command button by the operator, the system will then commence the full cleaning in a sequence of flow and rest cycles as programmed into a dedicated programmable logic control unit (PLC). During this time the cleaning agent is injected into the flow by pump 17, the duration of the pump being controlled by the PLC, enabling accurate metering of the cleaning agent. At the end of the wash cycle the valve 6 is cycled to load and unload the pump 4, thus pulsing the flow and dislodging any obstinate debris. After this the PLC controls the rinse cycles to ensure thorough rinsing of all lines and components.

Abstract: The data storage system in a storage unit has a file system that comprises a main memory in which the file system is loaded. The file system divides the storage space into separate high and low reliability areas. The high reliability area is for management data and the low reliability area is for the contents data. The data stored in the high reliability area may when accessed have retry or sector remapping performed, whereas the low reliability area has none, or a level such that real time data processing can be done. The areas may be composed of contiguous blocks. The area which contains the high reliability area may be checked in advance and the boundary between the areas may be changeable. The data may be stored in the different areas according to the file identifiers and the management data stored in the high reliability area may relate to the content data held in the low reliability area.

Title: A class D amplifier with a guard band quantizer to prevent output of narrow pulses
Inventor: MAGRATH ANTHONY JAMES
IPC: H03M7/32
Filed: 2005-01-17
Abstract: A PWM circuit comprises a quantiser arranged to block low level signal inputs to the modulator stage, thereby preventing the output of very narrow pulses. For low level signals between threshold TL and TU the quantiser outputs either a zero output or a code representing a minimum desired pulse width. This ensures that either no pulse is output from the PWM or else a pulse having at least a minimum width is produced. The H-bridge may be controlled by relatively long non-overlapping pulses, thereby reducing predriver power consumption (figures 11 and 12). Double-sided PWM using shuffling of the leading edge is disclosed. The use of a noise shaping loop around the shuffler quantizer (figures 9 and 10) allows odd pulse lengths to be output without distortion or noise.

Title: Tamper proof anti-theft detection for a vehicle's roadwheels
IPC: B60R25/10
Filed: 2005-02-08
Abstract: A pressure sensor switch 6 fitted at the top of a hollow piston rod being part of a shock absorber 4 in order to detect internal hydraulic oil pressure changes during the unit's extension or compression and electrically connected into a vehicle's electronic alarm system as an extension of a vehicle's anti-theft electronic monitoring sensor loop in order that horn and hazard light theft indicators may be activated whenever a protected roadwheel is being illicitly removed whilst the vehicle is parked and locked with its anti-theft alarm system set on alert mode. An insecure wheel indicator of attempted roadwheel tampering may be included in order to prevent a subsequent driver from driving a dangerous vehicle that has loosened or missing wheel nuts. All parts of this system being inaccessible to thieves would therefore present tamper proof protection that thieves may find they are unable to overcome. In a further embodiment the illicit raising of a wheel can be detected by laser or sonic sensors located in the boot and bonnet compartments of the vehicle. Alternatively a magnetic proximity switch can be fitted to detect excessive displacement of the vehicle suspension.

Title: Integrated circuit comprising an SSTL (stub series terminated logic) pre-driver stage using regulated power supply and method for performing an SSTL operation
Inventor: AMICK BRIAN W
IPC: H03K19/0185
Filed: 2003-08-08
Abstract: A SSTL memory interface pre-driver stage (24) that uses a voltage regulator (32) to generate "virtual" supply and ground voltages is provided.

Title: Tuner with integrated tracking filter employing switchable capacitors
Inventor: SAWYER DAVID ALBERT
IPC: H03J1/16
Filed: 2005-06-08
Abstract: A radio frequency tuner comprises one or more tracking filters 11, 14 (fig.2) ahead of at least one frequency changer 12, 15 (fig.2). Each filter 11, 14 has one or more resonant networks comprising an inductance 46 and a plurality of capacitors 48 (fig.5) which are individually switchable into the network under digital control for selecting the resonant frequency of the network. The capacitor values may be binarily weighted. A controller 58 (fig.7) has a filter alignment mode and a reception mode. In the alignment mode, the controller 58, in conjunction with a tone generator 57 and a level detector 60, determines the difference between the nominal and the actual capacitance 48 required in the filter network in order to achieve a required resonant frequency. The controller thus determines a correction factor which is used during normal reception by the tuner. The individually switchable capacitors may be implemented on an integrated circuit and the relatively high tuning voltages associated with conventional varactor diodes are not required.
