Title: Using a Bayesian Belief Network to model system reliability
Inventor: GRAS JEAN-JACQUES
IPC: G06F11/36
Filed: 2001-07-05
Abstract: A method of determining probabilities associated with a sequence of events in a system, for example an item of software or a software system being developed. A scenario, e.g. a message sequence chart, MSC (1,51), is parsed into a directed acyclic graph, DAG (21), comprising nodes (22) and edges (24), by associating the nodes (22) to events, and by associating the edges to messages (8, 10) and sequential relations between consecutive events in the MSC (1,51). A Bayesian belief network, BBN (31), is formed using the DAG (21). BBN conditional probability tables associated with each event are computed, and the overall probabilities associated with the sequence of events is determined from the BBN conditional probability tables. This can be used to provide analysis of reliability early in a software development cycle. Alternative applications, such as to project management, are possible.

Title: Method of operating a fluid contaminant sensor
Inventor: BAKER MICHAEL CHARLES
IPC: G01N15/06
Filed: 2002-08-29
Abstract: A method for measuring the contaminant level in a fluid using an annular test passage 48, which gets progressively occluded or blocked by contaminants, and a variable-volume chamber 47. The following steps are carried out at least twice: directing a flow of fluid through the test passage into the chamber; measuring the rate of change of volume of the chamber using LVDT 44; determining the fluid flow; determining the volume of fluid to have passed through the test passage in a given period; calculating the cumulative volume of fluid which has passed through the passage and estimating the total volume of fluid which will flow through the passage before it gets blocked completely. The level of contamination is related this estimated total volume. The estimate is based upon the ratio of the initial and final values of the measured flow therefore eliminating errors due to fluid temperature.

Title: Apparatus for encryption and decrytion, capable of use in encryption and decryption of Advanced Encryption Standard (RIJNDAEL)
Inventor: LU CHIH-CHUNG
IPC: H04L9/06
Filed: 2002-09-24
Abstract: Apparatus capable of use in encryption and decryption of advanced encryption standard combines a byte substitution operation and an inverse byte substitution operation. The byte substitution operation can be expressed as <F>y = M *</F> multiplicative_inverse(x) + c while the inverse byte substitution operation can be expressed as <F>x = multiplicative_inverse(M<SP>-1</SP>*(y+c))</F>, wherein M and M<SP>-1</SP> are inverse matrix of each other and c is a constant matrix. Since the two equations employ a look-up table, that is, multiplicative_inverse(x), the lookup tables for use in byte substitution and inverse byte substitution operations are combined according to the invention so as to reduce hardware complexity. In addition, the main operations of column mixing and inverse column mixing are rearranged to combine the two operations in part, resulting in simplified hardware implementation.

Title: Variable air intake system valve construction, eg for i.c. engines
Inventor: INO MASAO
IPC: F02B27/00
Filed: 2003-07-17
Abstract: A rotary shaft 40 holds valve members 30 each disposed in an air intake passage 131-134. The valve members 30 are made from a resin, eg polyamide resin, and are press-fitted on the shaft which is made from austenitic stainless steel, a metal of the aluminium family or a metal of the copper family so that the coefficient of linear thermal expansion of the shaft is more similar to that of the valve members than would be the case for an iron shaft. Thus the formation of clearances between the shaft 40 and the valve members 30 is inhibited even if the temperature changes and noise and vibration is reduced. Moreover, the shaft 40 does not need to be plated against corrosion, improving dimensional accuracy.

Title: Determining a power relationship linking the transmit powers of user data and associated control data
Inventor: FEATHERSTONE WALTER
IPC: H04B7/005
Filed: 2003-11-21
Abstract: In a communication system where user data and associated control data are transmitted from one entity to another, a power relationship linking the transmit powers of the user data and associated control data is determined at least partly dependent on a received quality of the associated control data. For example, if the bit error rate (BER) of the received control data is found to be below a desired threshold, an increase in the control transmit power is required and a new power relationship (e.g. a different offset or ratio) is determined which enables the required increase in the control transmit power whilst maintaining the data transmit power at a level set by an outer power control loop. Conventionally, a set relationship is established between the data and control transmit powers and the transmit power of the data channel is optimised using inner and outer loop power control. However, in such systems the control power is not optimised as it merely follows the data power according to the set relationship. Implementation of the described method results in the ability to maintain the transmit power of the user data, (e.g. on a Dedicated Physical Data Channel (DPDCH) in UMTS), at an optimum power level set by a power control process, whilst ensuring that associated control data, (e.g. on a Dedicated Physical Control Channel (DPCH)), is also transmitted at an optimum power level. The invention ensures reception of the user data and control data with an acceptable error rate causing minimum interference to other users. New quality targets may also be generated for the power loop control processes.
