Title: Evolution of performance model
Inventor: ZEDDA MARCO
IPC: G06Q10/00
Filed: 2000-05-09
Abstract: A method for estimating the performance of and/or detecting faults in a multi-component system, eg a gas turbine (fig 4). The system can be defined by a function h() of the performance parameters x and operating parameters w defining an operating condition of the system. An initial population of strings is created consisting of a number of elements corresponding to estimated values of performance and operating parameters. The method comprising optimising an objective function J(x,w) which relates the function h() to measured parameters Z based on M<SB>bias</SB> which is the maximum number of fault effected measurements using genetic algorithms to create successive populations of strings. A selection process is used to generate the next population of strings by eliminating strings from the population which have a low fitness value based on the objective function and creates cross-over and mutation strings to add to the population. Multiple calculations of the objective function are performed with a different M<SB>bias</SB> eliminated then selecting the formula used to produce the minimum calculation of the optimisation function.

Title: Current profile shaping to reduce disc drive seek time variation and acoustic noise generation
Inventor: LIU ZHIGIANG
IPC: G11B33/08
Filed: 1999-07-13
Abstract: Apparatus and method for reducing the generation of acoustic noise in a disc drive (100). A seek is carried out to move a head (120) from an initial track to a destination track on a disc (106) in relation to a velocity profile table (304) which provides a sequence of demand velocities indicative of the desired velocity as the head is decelerated to the destination track. During the seek, current (300) is applied to an actuator motor (116) to accelerate the head away from the initial track in relation to tables (310, 312, 314, 316) storing open loop current command values. A gain convergence block (318) increments servo gain (236) to provide a smooth transition between open and closed loop operation. Thereafter, the head is decelerated by applying current in relation to velocity error and current command values from a current profile table (306) defining deceleration of the head using maximum current.

Title: Recognition of a fault current at a piezoelectric actuator or a feed thereof
Inventor: RUEGER JOHANNES-JORG
IPC: F02D45/00
Filed: 2001-07-06
Abstract: A method of recognising a fault current at a piezoelectric actuator 5 of an injection valve, or at the feed 6, 6a thereof conducting high voltage, addresses the difficulty that the fault current, for example due to contact by a person, is relatively small by comparison with the effective current which charges or discharges the actuator, so that a direct current measurement is not reliable. Accordingly, the voltage change, during the injection or in an injection pause, when the actuator 5 is charged, is measured to obtain a difference value and the difference value is compared with a predetermined threshold value. If the threshold value is exceeded, a fault report is issued, the voltage supply is switched off and/or the actuator 5 is discharged. The measured fault can be weighted by a numerical algorithm for more secure recognition of the fault.

Title: Merging apparatus and method, re-introduction of initially rejected items back into a sequence of items
Inventor: BRITTON DAVID
IPC: B07C3/00
Filed: 2002-07-12
Abstract: A merging apparatus 2 comprises a housing 10, a plurality of linked moveable merging bins 16, data input means and control means. The data input means receives data, such as input by hand, which identifies the desired prospective position of an item in an item sorting sequence, the data also corresponding to the position of one of a plurality of linked moveable merging bins 16. Once such data is entered, connected control means actuates movement of the linked bins 16 such that the correct bin 16 is presented to a input position 36 such that the item may be placed in the bin 16, in its correct place in the sequence. Also disclosed is an associated method much as already described, in which it is further specified that the items are merged into an existing pre-sorted series of items already present in the in the merging bins. The items may be mail items such as letters, and the data, may be the addresses on the front of these. The sequence may correspond to a delivery route for a postal worker. The apparatus may permit the reintroduction of initially rejected mail items, back into a steam of pre-sorted, non-rejected mail items, from a single position, negating the need for a user to move between a set of bins. Mail items initially rejected, such as due to the address being non-machine legible in an initial upstream sorting process, are re-introduced in their correct place in the sequence at the apparatus. The apparatus may feed sequenced items into an encapsulator 4.

Title: Determining transmission priority for data frames from a plurality of queues
Inventor: TSUBOTA KEISUKE
IPC: H04L47/6275
Filed: 2002-08-22
Abstract: A forwarding table 7 where a next transmission queue is registered is sequentially transferred within a queue chain 30 as a group of queues 131. If a priority of a queue to which the forwarding table 7 is transferred is higher than that of a queue registered in the forwarding table 7 as a next transmission queue, a next transmission queue number or the like is updated. Further, an arbiter 8 outputs a transmission command to a queue registered as the next transmission queue in the forwarding table 7 which has been transferred through all the queues, to transmit the next data frame from the queue having the highest priority. By this arrangement, it is possible to determine data frame transmission priorities among plural queues easily and efficiently while insuring a minimum guaranteed rate defined in each queue.

Title: Oil pump for controlling planetary system torque
Inventor: PHELAN PERRY EDWARD
IPC: F04C14/26
Filed: 2002-11-19
Abstract: This invention provides the use of a pump (10) to regulate torque in a planetary gear system. The pump is provided with a moveable piston (20) as an end plate. An actuator (50), attached to the piston, controls the movement of the piston. In one position, the piston is in contact with the internal components of the pump. When the actuator moves the piston, the piston loses contact with the pump, thus allowing a free flow of fluid between the inlet (12) and outlet (14) of the pump. In this configuration, the pump is no longer able to generate the pressure that creates torque in the planetary gear system.
