Title: DVB interleaver for odd/even symbol streams splits memory for sub-carrier number up to half maximum/has common memory and immediate location reuse otherwise
Inventor: TAYLOR MATTHEW PAUL ATHOL
IPC: H04J11/00
Filed: 2007-11-20
Abstract: DVB uses OFDM transmission in 2/4/8k sub-carrier modes. Known interleaving methods split symbols into odd and even streams for placing on sub-carriers. Odd symbols are written into sequential memory locations (132) and then read out in a permuted order (134), even symbols are written into permuted memory locations (120) and read out in a sequential order (126). If the permuted orders are identical it is possible to write a symbol into the memory location that has just been 'vacated' by a read operation. The sequential write permuted read interleaving performs better (See Fig. 6). Therefore the invention proposes splitting the memory and using this scheme for both odd and even symbol streams when the number of sub-carriers is less than or equal to half the maximum number, and the memory can accommodate the two streams without the need to immediately reuse memory locations. In order to avoid the same symbol appearing on the same carrier for every frame an offset (400) can be added or the permutation matrix can be varied.

Title: A conductive ground arrangement for a satellite communication antenna
Inventor: GRANGER ROBIN
IPC: H01Q1/48
Filed: 2008-05-20
Abstract: A ground arrangement for an antenna comprises first and second planar conductors 102, 103 arranged substantially perpendicular to a central axis of an antenna 101. The planar conductors 102, 103 are spaced from one another by a third conductor 104 arranged substantially parallel to the central axis. The second planar conductor 103 extends radially over the first planar conductor 102 by a distance of the order of one sixth of a wavelength of an operating frequency of the antenna. The conductive ground is arranged such that a radio wave propagating across an upper surface of the first planar conductor 102 is reflected away from the antenna 101. The spacing between the planar conductors 102, 103 may be in the order of one fifth of a wavelength. The planar conductors 102, 103 may be radially symmetric. The third conductor 104 may be in the form of a hollow cylinder and an end plate 108 may close the end of the cylinder distal from that associated with the antenna 101. The antenna 101 may be a patch or spiral element located inside of, and spaced from, the cylinder wall. The ground arrangement may reduce the effects of multipath radio signals arising in satellite communication systems.

Filed: 2009-02-25
Abstract: A method for operating an internal combustion engine, wherein at least a first map (10) of prefixed first values is predetermined, each prefixed first value being a function of a prefixed nominal fuel quantity (0ecu_prefix). According to the invention the method comprises the steps of determining a nominal fuel quantity (Qecu) for one injection, calculating an actual, torque forming, injected fuel quantity of the injection (Quego) and calculating at least one first parameter (Qdelta) which is related to the actual, torque forming, injected fuel quantity of the injection (Quego). After that, the nominal fuel quantity (Qecu) is modified according to the value of the at least one first parameter (Qdelta) so as to obtain a corrected fuel quantity (necuCorr) that corresponds to the actual fuel quantity injected during the injection. The method further comprises the step of comparing the corrected fuel quantity on each of the prefixed nominal fuel (ecuCorr) with quantity (Qecu) and operating the engine using, from the first map (10), the first values which corresponds to the corrected fuel quantity (OecuCorr) according to the result of said comparison.

Title: Control of a high speed brushless motor
Inventor: CLOTHIER ANDREW CHARLTON
IPC: H02K21/12
Filed: 2009-04-04
Abstract: A motor system (5, fig.2) comprising a single phase brushless dc motor and its control system are disclosed. The motor is suitable for operation at high speed, for example at speeds above 60,000 revolutions per minute (rpm). It is suitable for use in a vacuum cleaner. The motor includes a single winding (19, fig.3) arranged on a C-shaped core (8, fig.3) which enables a high fill factor to be achieved for the winding. A Hall position sensor is used. In operation, the winding 19 is sequentially excited and freewheeled by a conventional H-bridge drive circuit. It is disclosed that the winding is excited in advance of zero-crossings of the back-emf in the winding by an advance angle, and is freewheeled over a freewheel angle. Both the advance angle and the freewheel angle may be varied in response to changes in the speed of the motor and the excitation voltage. The variation of the advance angle and freewheel angle is stored in the drive controller (16, fig.2) as a power map. Each power map comprises a lookup table storing an advance time and a freewheel time for each of a plurality of voltage levels. Consequently, constant output power is achieved over an operating speed range spanning at least 10,000 rpm, irrespective of changes in excitation voltage, which may come from a battery.

Abstract: 840,585. Selective printing. KOOPERATIVA FORBUNDET EKONOMISK FORENING. March 31, 1958 [March 30, 1957], No. 10329/58. Class 100(4). An electrically controlled printing apparatus comprises a series of synchronously operated type-members e.g. type-wheels 3, Fig. 2, which are arrested individually at required positions by magnetically operated stops 18 automatically controlled by pre-selection determined by a plurality of coupling members 70, Fig. 8, each consisting of two sets of contacts 66, 67 and each provided with a particular pattern of interconnections so that required characters are printed in the required columns. The coupling members 70 are mounted in parallel slots S in a selecting device comprising a framework 49, 50, 51 Fig. 4 and the contacts 66 of each are all in contact with rails 47 A-M,the contacts 67 are selected by movement of a contact arm 54 suspended on a travelling carriage 52 which is coupled to an indicator 59. To effect printing, which is made in one line at a time, a handle 38 is moved and a motor 5 commences and continues to run because a cam 40 closes contacts 41. A wiper 42 serially makes with contacts A-M in synchronism with rotation of the type-wheels 3 so that when a required character is in printing position above a hammer 25, a circuit is completed from the wiper, through the particular connection in the coupling member 70 to an electromagnet 19 which operates a stop 18. When the stop engages a notch in the back half of the type-wheels the driving shaft 4 continues to rotate to position the remaining type-wheels. This slipping connection comprises a spring plunger 15 radially mounted in the shaft 4 and co-acting with a cam groove 15 on the inside of the type-wheels. When the shaft 4 has rotated 180 degrees, printing occurs and the typewheels are then reversed to their home position, effected by a segment gear 14 engaging a rack 12 which is moved in direction opposite that made by a segment gear 13 during the setting operation. The printing apparatus may comprise two sets of type-wheels, a first for printing invoices which are fed along the guideway 231 and printed by the wheels 3, and a second set for printing on cards which are stored adjacent to the corresponding coupling member 70. The cards are partly raised by a lifting arm and then placed in position for printing by the second set of type-wheels.
