Patent GB-2350305-A (GB)
Title: Steerable roller skates
Inventor: TREW MICHAEL
IPC: A63C17/02
Filed: 2000-03-13
Abstract: A steerable roller skate comprises either front and back pivotable ring-shaped members 1 with pairs of wheels 4 attached, or front and back pivotable C-shaped members (2, Fig 2) attached to the axles of pairs of wheels. Pivot points 2 and (3, Fig 2) on the ring and C-shaped members, allow the skate to be steered when leaned into a turn. The ring or C-shaped members may be attached directly to footwear as shown or to a base-plate (5, Fig 2) onto which the footwear is attached. The base-plate may be an elastomeric block to provide suspension and resistance to steering. The roller skate may include footwear with a channel (2, Fig 3) along the length of the sole (1, Fig3), and an elastomeric band (3, Fig) which fits into the channel. The C-shaped members may be moulded into the elastomeric band, and the axles pass through holes in the band. A grind plate (9, Fig 3) may be attached to the elastomeric band by bungees (7, Fig 3). The movement of the ring or C-shaped members is limited by elastic chords or similar means to return the wheels to the original alignment when the skate is not leaned on.

Title: Emission device temperature control system
Inventor: FARMER DAVID GEORGE
IPC: F01N13/04
Filed: 2000-05-18
Abstract: A nitrous oxide trap temperature control system for desulfating the trap uses an engine with some cylinders operating with lean combustion and some cylinders operating with rich combustion. The lean and rich combustion gases are combined to form an mixture which is fed to the trap to provide an exothermic reaction. The desired lean and rich air/fuel ratios of the respective lean and rich cylinders are limited depending on trap temperature and incremental heat addition to prevent inadvertently decreasing trap temperature.

IPC: B41M5/52
Filed: 2000-06-05
Abstract: A spool 2 has printing paper 3 wound on it and a detection portion 2a on the spool, which allows detection of rotation of the spool. The detection portion may comprise a notch 2a on at least one end of the spool or a mark such as a bar code (51) formed on the inside of at least one end of the spool. There may be spigots 5, 6 which rotatably support the spool. There may be rotation detection means 7, which may form part of a spigot. The spigots may have shafts 5a, 6a and flanges 5b, 6b, and one of the spigots 5 may have a through-hole 5c. A portion 8a of a lever 8 is biassed through hole 5c with a spring 10. When the spool rotates, lever portion 8a comes into and out of contact with the notch 2a through hole 5c by pivoting about pin 9, which is detected by optical sensor 12 via lever portion 8b. A video printer may comprise such an arrangement, coupled with means for detecting whether the paper is almost completely consumed and displaying an alarm to indicate this. There may be a second alarm to indicate that rotation of the spool is not detected. There is also a method of determining the quantity of remaining printing paper on a spool and displaying an alarm if the paper is almost completely consumed.

IPC: H03M7/30
Filed: 2000-10-05
Abstract: A method is disclosed for compressing a frame of data representing parameter values, a time at which each parameter value was recorded, and an orientation (azimuth) of a sensor at the time each parameter value was recorded. Generally the method includes performing a two-dimensional transform on the data in the orientation domain and in a domain related to the recording time.

Title: Distributed computing system
Inventor: THORDARSON ALFRED B
IPC: G06F9/445
Filed: 2001-02-13
Abstract: Client computers have a class loader and stored class definitions. The class loader initially determines whether a referenced class definition is one of those stored on the client computer and, if not, downloads the relevant class definitions, reinitiates and continues processing. This arrangement means a smaller set of class definitions can be held on a client computer of limited storage, enabling it still to execute large application programs.

Title: Compiling methods for parallel processing
Inventor: FERNANDES MARCIO MERINO
IPC: G06F9/45
Filed: 2001-10-12
Abstract: A compiling method compiles an object program to be executed by a processor having execution units operable in parallel. An availability chain is created from a producer instruction (p1), scheduled for execution by a first execution unit (2 0 : AGU), to a first consumer instruction (c1), scheduled for execution by a second execution unit (2 2 : EXU) and requiring a value produced by the producer instruction. The chain comprises at least one instruction (mv1-mv3) for moving the required value from a first point (2 0 : ARF) accessible by the first unit to a second point (2 2 : DRF) accessible by the second unit. When a second consumer instruction (c2), also requiring the same value, is scheduled for execution by an execution unit (2 3 : EXU) other than the first unit, at least part of the chain is reused to move the required value to a point (2 3 : DRF) accessible by that other unit. In other compiling methods (Fig. 8), the object program includes a loop kernel block and a basic block preceding it, the basic block includes a producer instruction and the loop kernel block includes a consumer instruction. The loop kernel block is scheduled first, after which the basic block is scheduled. These methods can put additional move instructions between producer and consumer instructions in the basic block instead of the loop kernel block, or eliminate the move instructions altogether.

Title: Frequency locker, e.g. for lasers
Inventor: FRASER JAMES
IPC: H01S5/0687
Filed: 2002-04-25
Abstract: An assembly (11) for frequency stabilisation of an optical signal especially from a laser (10), comprises a beam splitter (15), a passive frequency discriminator (16) such as a Fabry Perot etalon, or an interference filter, and a pair of photodiodes (17 and 18). The beam splitter (15) in use receives a collimated optical beam (B) and diverts a sample beam (B1) which is directed towards the discriminator (16) which transmits a portion (B2) of said sample beam to one of the photodiodes (17) and reflects a second portion (B3) of said sample beam to the other photodiode (18). A control signal (S3) is derived from the difference of the respective intensities of the transmitted and reflected portions of the sample beam, and utilised to operate the electronic control to adjust the frequency of the laser output signal, if required, to maintain a specified frequency. Summation of the respective intensities may be used to monitor optical signal power output of the laser. The control signal (S3) may be used to change the electrical operating conditions of the laser, or to change the set point of a thermo-electric control.
