Abstract: In a method for the spatial distribution of a component within the matrix of a composite a mixture comprising two or more components one of which is a non-conducting or weakly conducting fluid, e.g. an epoxy resin, and the other of which is at least one solid, liquid or gas capable of polarisation, e.g lead zirconium titanate, is contained in a receptacle and an alternating electric field is applied across two electrodes immersed in the mixture, with the electrodes being moved relative to each other during formation of the composite. An apparatus is described in which a first electrode 20 is at the base of a receptacle 10 and a moveable electrode, e.g. in the form of an array of needle-like structures 21-24 interconnected to form an integral electrode, is provided.

Title: Controlling the pump of a brake system
Inventor: WANDEL HELMUT
IPC: F04B49/06
Filed: 2000-04-19
Abstract: The pump motor achieves full drive for time TAnstMax (t1-t0) following a braking request from a brake system. During the subsequent clocked driving action (starting at t1), drive signal UP is subjected to pulse width modulation (t7-t1) based on a direct comparison between motor voltage UM and a voltage threshold value US (e.g., t4). Due to a subsequent comparison between motor voltage UM and a safety threshold Uss (e.g., t7), and the resulting full drive for TAnstMax (e.g., t9-t8), an increased load on the pump causes the latter to produce the necessary delivery capacity. In addition, a selectable maximum off-time TPausMax (e.g., t3-t1) of the pump motor guarantees a minimum pump on-time TPeinMin (e.g., t2-t3) per drive cycle TTakt (e.g., t2-t1). The pump can be made to achieve full drive prematurely as a function of certain conditions which can be subjected to a preventive check, thereby avoiding an excessively high load. It is also possible to coordinate the way in which different brake control strategies access the pump.

IPC: B60N2/90
Filed: 2000-05-06
Abstract: A seat 1, such as a passenger aeroplane seat, comprises pivotally interconnected seat back 2 and seat members 4 movable together in a single action in which seat 1 as a whole opens out, (in transition from fig.2 to fig.1) as the seat back 2 tilts backwards and moves downwards, and the seat member 4 moves forwards. This action might also be described as a rocking facility in which the seat member 4 and seat back 2 in combination may be said to rotate around a common virtual axis 14. The seat may be provided with arcuate guides 10, 12 and corresponding extensions 6, 8 to enable such an action. The seat member 4 may tilt independently (fig.6) to a position adjacent the seat back 2 to aid the passage of a user past the seat 1.

Patent GB-2365295-A (GB)
Title: Watermarking key
Inventor: SEWELL ROGER FANE
IPC: G10L19/018
Filed: 2000-07-27
Abstract: To watermark a covertext comprising audio or video signals 10, a two-dimensional noise pattern of predetermined height and width is generated and filtered in one dimension with a cut-off frequency which varies with the position in the pattern. This is used to generate a key 1 which is used by an encoder 2 to watermark the covertext and which can be used subsequently by a decoder 3 to decode the resulting stegotext 15. The key may be used by the encoder to modulate the log power spectrogram 11 obtained by fast Fourier transformation and rectangular polar conversion of the covertext signal. The origin of the covertext can thus be identified in an imperceptible way, and unauthorised reproduction of the covertext may be prevented.

Title: Interface device and method for interfacing instruments to vascular access simulation systems
Inventor: CUNNINGHAM RICHARD L
IPC: G06Q50/00
Filed: 1999-01-28
Abstract: An interface device and method for interfacing instruments to a vascular access simulation system serve to interface peripherals in the form of mock or actual medical instruments to the simulation system to enable simulation of medical procedures. The interface device includes a catheter unit assembly for receiving a catheter needle as assembly, and a skin traction mechanism to simulate placing skin in traction or manipulating other anatomical sites for performing a medical procedure. The catheter needle assembly and skin traction mechanism are manipulated by a user during a medical procedure. The catheter unit assembly includes a base, a housing, a bearing assembly and a shaft that receives the catheter needle assembly. The bearing assembly enables translation of the catheter needle assembly, and includes bearings that enable the shaft to translate in accordance with manipulation of the catheter needle assembly. The shaft typically includes an encoder to measure translational motion of a needle of the catheter needle assembly, while the interface device further includes encoders to measure manipulation of the catheter needle assembly in various degrees of freedom (e.g., translation, pitch and yaw) and the skin traction mechanism. Alternatively, the shaft may include an additional encoder to measure translational motion of an instrument inserted through the catheter needle assembly. The simulation system receives measurements from the interface device encoders and updates the simulation and display, while providing control signals to the force feedback device to enable application of force feedback to the catheter needle assembly.

Title: Flash memory contents protection by use of a data and address scrambling IC
Inventor: HOU CHIEN-TZU
IPC: G11C16/22
Filed: 2000-10-20
Abstract: Data for secure storage in a flash memory 10 is first partitioned into blocks. The data blocks are then rotated (figure 5) so that bits from each data element in the original block are distributed across several data elements in the rotated block. The rotated data is then stored in the flash memory at an address generated by the address scrambler 31. When reading from the flash memory, a random sequence generated by a random number generator 32 causes dummy data to appear in the stream of rotated data retrieved from the flash memory. The decoder 33 filters out the dummy data using a key 35 and performs an inverse rotation. The key 35 reflects a particular address mapping sequence so that useful data may be distinguished from dummy data. In an alternative embodiment (figure 8), an address scrambling conversion table is stored in a small PROM or flash memory in the IC.

Title: A device for watering plants in elevated locations
Inventor: BATER DENNIS
IPC: A01G25/14
Filed: 2001-07-03
Abstract: A plant watering device 1 for delivering liquid to an elevated location, eg. a hanging basket, comprises a water reservoir 3, such as a bottle, held in a support cradle 4 mounted at the upper end of an elongate handle 2. In use, the reservoir 3 may be filled by plunging it into a bucket of water. To water a hanging basket in an elevated position, an operator holds the handle 2 and manipulates the device to a position in which the reservoir 3 is above the hanging basket. When suitably positioned, the handle 2 is rotated by the operator so that the neck 30 of the reservoir 3 faces generally downwardly and water falls from the reservoir 3 under gravity. The reservoir 3 may be secured to the cradle 4 by loops 5, 6, such as ratchet-action ties. A further embodiment is described wherein the cradle 4 is pivoted to the handle 2 and held by a cord (54, fig.3), such that slackening of the cord allows the reservoir 3 to tilt and dispense the water.

IPC: G07F17/32
Filed: 2001-09-17
Abstract: A coin dispensing device for an entertainment machine has a passageway (46) between an outlet (8) and a coin store (19). Dispense of coins from the store (19) is effected by a motor-driven feed device (50). A controller (40) which controls operation of the feed device (50) is located within the coin store (19) and is connected to a coin sensing arrangement (42, 44) in the passageway.
