Patent GB-2318234-A (GB)
Title: Oscillator circuit
Inventor: TCHAMOV NIKOLAY
IPC: H03K3/012
Filed: 1997-05-07
Abstract: The invention relates to an oscillator circuit. The circuit comprises two main transistors (Q1, Q2), between which is provided a positive feedback by connecting each transistor base to the collector of the other transistor via buffer transistors (Q3, Q4). A capacitor (C) is connected between the emitters of the main transistors. The frequency of the oscillator is controlled by two current sources (I1, I2), which control the current (I1, I2) flowing through the capacitor (C). Additionally, a compensation current (Icom) is conducted via collector resistors (Rc1, Rc2) of the main transistors in such a way that the current flowing through each resistor is essentially constant and independent of the control current (I1, I2). So the signal amplitude of the oscillator does not change during frequency control.

Abstract: A blood pump for assisting a heart is provided having a stator (1) and a rotor (2). The rotor is magnetically radially supported creating a suspension gap between the stator and the rotor. The rotor is supported axially by a Lorentz force bearing (13-18) and can be magnetically rotated. The stator can have a single or double volute pump chamber and the rotor can have an impeller portion (10) for pumping blood. The rotor can have a center bore as a primary blood flowpath (20'). The suspension gap (21) can be a secondary blood flowpath. The blood pump can also have an axial position controller and a flow rate controller. The axial position controller can cause the axial bearing to adjust the position of the rotor. The flow rate controller can have a member for measuring a dimension of a heart ventricle to control the flow rate to avoid overly distending or contracting the ventricle. A method of operating the flow rate controller to create a pulsatile flow rate is also provided. Additionally, the blood pump can be part of a cardiac assist and arrhythmia control system. Moreover, a method of operating the flow rate controller can be provided which reduces the amount of energy needed to treat fibrillation. The method can include operating the flow rate controller to reduce a radial dimension of the ventricle prior to delivering defibrillation energy such that the ventricle contains less blood which absorbs less energy so that a larger fraction of the energy is delivered to the heart.

Patent GB-2341956-A (GB)
Title: Transaction management in a configuration database
Inventor: TRAVERSAT BERNARD A
IPC: H04L12/24
Filed: 1999-05-18
Abstract: A method and system are disclosed for updating and managing a configuration database 101 used to store configuration and user data in a computer network having multiple clients, such as network computers 105. The transaction management mechanisms described determine whether new data, such as a new user or specific property, is being added to the configuration database or whether an existing node in the database is being modified by a transaction. A locking mechanism obtains a lock on a node according to whether a new node is being added or an existing node is being modified. During this process, an identifier is assigned to the transaction that caused the lock, that acts as a transaction handle. The transaction then proceeds to modify the configuration database by either adding new data or modifying existing data. The locking mechanism then commits the transaction by releasing the lock if the modification or insertion is successful, or aborts the transaction if the modification or insertion fails. If the transaction is aborted, the database is rolled back to an initial state by referring to a transaction event log.
Patent GB-2341032-A (GB)
Title: Motion-dependent scanning frequency conversion
Inventor: KO DO-YOUNG
IPC: H04N5/44
Filed: 1999-06-08
Abstract: A motion-dependent frequency converter apparatus for use with an MPEG decoding block employs a double-scan converting method to double the vertical scanning frequency of a decoded MPEG video signal in order to enable screen flicker to be reduced. This is achieved by consideration of the size of the motion vectors calculated between adjacent image fields. If the size of the motion vector exceeds a predetermined threshold value, a mean-calculated field is interpolated between existing fields. If the size of the motion vector does not exceed the threshold value, the original field is repeated before the next field in sequence is output. In an alternative embodiment to improve image resolution, a progressive-scan converting method is used to double the horizontal scanning frequency of a decoded MPEG video signal. An intermediate line is interpolated between existing lines, the new line being either: <UL ST="-"> <LI>a mean-calculated line from the corresponding lines of the prior and subsequent fields when the size of the motion vector exceeds a predetermined threshold value or, <LI>a line which is the repeat of the corresponding line from the previous field when the size of the motion vector does not exceed the threshold value. </UL> The above methods allow scanning frequency conversion whilst obviating the need for a signal interpolating memory and a motion detecting memory as are commonly used in MPEG decoding.

Title: Data recovery in an OFDM system exploiting pilot subcarriers
Inventor: KNUDSEN KNUD
IPC: H04L1/00
Filed: 1999-11-09
Abstract: A receiver for an orthogonal frequency division multiplexed (OFDM) system includes a symbol distortion estimator 18 which provides an estimate of the channel response by comparing received pilot symbols with locally stored copies or with a threshold. A sub-carrier correction/erasure location means 22 receives the channel response estimate and provides a signal to an equalizer 20 or a decoder 24 (or both) to discard corresponding data symbols when the channel response suggests that they are corrupt. The decoder may be a block decoder such as a Reed Solomon (RS) decoder. The OFDM signal may be modulated with random phases chosen such that they whiten the signal, i.e. reduce the peak to average ratio.

Title: Intelligent transaction monitoring
Inventor: KINGDON JASON
IPC: G06Q30/00
Filed: 1999-12-23
Abstract: An automated system and method that uses models of business activity to automate business monitoring and analysis tasks. The system builds profiles, 230, of historical business transactions and performs comparative analysis, 261, 262, between these profiles and new, unseen data. In this way, the system can classify and make judgements about new, unseen, transactions and alert operators to unusual transactional patterns. Operators may also be alerted when the system recognizes prescribed patterns of activity. The system provides a means to update the historical activity profiles and maintain them such that they may be used to provide supporting evidence in order for operators to make decisions about alerts generated by the system and to perform other forms of analysis on the transactional data. Alerts generated by the system are ranked according to their relative importance and may be assigned for processing by a specific operator, or group of operators. The system may be used e.g. to detect fraud, or for risk analysis, regulatory compliance checking, marketing or product-wage analysis.
