Title: Measuring and optimising diffusivity of acoustic output of loudspeakers
Inventor: HILL NICHOLAS PATRICK ROLAND
IPC: H04R29/00
Filed: 2001-02-15
Abstract: A method to obtain a desired level of diffusivity of acoustic output from an acoustic device comprises measuring a reference response of the device and at least one other response, and calculating a correlation between these responses. At least one parameter of the device is varied and the responses remeasured. The parameter giving a correlation closest to a predetermined optimum correlation value is selected in order to obtain the desired diffusivity. Also disclosed is a method for measuring the diffusivity of the acoustic output of an acoustic device, where the correlation between device responses at two positions is correlated, providing a measure of diffusivity. The methods are applied particularly to the design of bending-wave panel loudspeakers.

Title: Conditioning of an ion beam for injection into a time of flight mass spectrometer
Inventor: FRANZEN JOCHEN
IPC: H01J49/40
Filed: 2001-03-02
Abstract: The invention relates to a method and device which reduces the phase space volume of ions in an ion beam, in such a way that their injection into a downstream time-of-flight mass spectrometer optimises the performance of that spectrometer i.e. mass resolving power, sensitivity and temporal resolution. The invention consists of completely decelerating the ions 1 by means of collisions with a damping gas in a RF ion guide system 4, guiding them to the end 7 of the ion guide system 4 by active forward thrust provided by the damping gas, extracting them by a drawing lens system, and forming an ion beam having a low phase space volume. In particular, the ion guide system 4 can take the form of a pair of wires coiled in a double helix and be surrounded by an envelope which is filled with the damping gas (fig. 3).

Title: Method and apparatus for an interleaved non-blocking packet buffer
Inventor: BROWN DAVID A
IPC: H04L12/56
Filed: 2000-08-21
Abstract: Memory interleaving is performed to increase bandwidth of a common memory in a non-blocking switch. The switch receives packets from a plurality of ingress ports, stores the packets in the common memory, and forwards the packets to a plurality of egress ports. The common memory is physically divided into two banks to provide two way interleaving. Two way interleaving is performed by reading a packet to be forwarded to an egress port from one bank concurrently with writing a packet received from an ingress port to the other bank. The common memory is physically divided into four banks to provide four way interleaving. Four way interleaving is performed by concurrently reading and writing two even banks or two odd banks. Bank balancing techniques are also provided to keep the banks of the common memory at the same level of occupancy.

Title: A collapsible pedal box
Inventor: JASSERON MARC
IPC: B60R21/09
Filed: 2002-05-29
Abstract: A pedal box (10, Fig 1) supports a control pedal 14 of an automobile. The pedal 14 is pivotally mounted on a main pivot shaft 12 which goes through a elongate slot 30 in the pedal 14. The main pivot shaft 12 is normally held at one end of the slot 30 by a blocking plate 32 which is held in position by a latch member 36 wherein relative movement between the pedal box (10, Fig 1) and another member of the automobile causes the latch member 36 to release the latching engagement, permitting the blocking plate 32 to fall away and allowing the main pivot shaft 12 to traverse a slot 30 in the pedal together with rotation of the pedal 14 away from contact with the feet of a driver of the automobile. Advantageously although the pedal collapses and moves away from the driver's feet, its pivotable mounting is still maintained, so that some element of emergency control can still be established should the automobile still be drivable.

IPC: G06F13/00
Filed: 2003-06-12
Abstract: A method and design tool for modifying a design of a bus interconnect block for a data processing apparatus in order to meet a requirement for a chosen characteristic of the bus interconnect block. The bus interconnect block provides a plurality of connections via which one or more master devices may access one or more slave devices, each connection comprising one or more paths, and each path having one or more path portions separated by storage elements. The method comprises the steps of: (a) selecting one or more candidate paths from said paths; (b) for each candidate path, applying predetermined criteria to determine whether modification of the number of storage elements in said path will assist in meeting the requirement for said chosen characteristic; and (c) modifying the number of storage elements in each candidate path for which it is determined at said step (b) that modification will assist in meeting the requirement for said chosen characteristic. Such an approach allows design modifications to be made iteratively with limited impact on previously made decisions, and allows design modifications to be considered and implemented on a connection-by-connection basis.
