Title: An RF transmitter with distortion reduction by feedforward of a model-derived error signal
Inventor: SMITH CHRISTOPHER NIGEL
IPC: H03F1/32
Filed: 2008-08-27
Abstract: The expected distortion error of an RF power amplifier 2 is computed by use of an amplifier model 31 in the digital baseband stage 42. The error signal is fed forward and combined subtractively 40 with the power amplifier output to reduce distortion in the output signal 41. The output signal is fed back 52,53 to the estimator 33 for adaptation of the amplifier model, which employs polynomial techniques and can model memory effects (figure 7). Digital predistorters 30,37 may be disposed in the main signal channel and error signal channel respectively.

Title: Associating a foreign currency with an accounting object
Inventor: BACIGALUPI MICHELLE
IPC: G06Q40/00
Filed: 2009-09-22
Abstract: Companies often have to account for their transactions in one or more foreign currencies. However, accounting for different transactions in multiple foreign currencies typically required the creation of one or more accounts for each foreign currency in which a transaction was completed. Consequently, the present invention provides a method and apparatus that automatically associates a foreign currency with an object, such as an account or transaction form. First, a name is received from a user 602. Next, an association between the name and the foreign currency is determined 604, wherein the foreign currency is different from a home currency. Then, the object is automatically associated with the foreign currency associated with the name 608.

Title: Smartcard system using second session for fraud detection
Inventor: HOCHFIELD BARRY SIM
IPC: G06F21/77
Filed: 2006-06-06
Abstract: The invention provides an ITSO-based smartcard system including a programmable smartcard device for use in the ITSO scheme carrying a file system and operating software enabling the on-device file system to interface with at least one off-device ITSO application. At the interface, the off-device ITSO application is permitted to access and/or modify data in the on-device file system. Inter-engagement of the smartcard device with the interface device causes the interface device to generate a session key used in the encryption/decryption of data and/or commands during a sequence of operations carried out to access and/or modify data carried by the programmable smartcard device. Completion of a sequence of operations to modify data on the programmable smartcard device causes the interface device to open a new session and to generate a second session key and to use that second session key to verify that the required data has been modified in accordance with the intended sequence of operations. The invention is thus capable of providing an ITSO based system with better protection against fraud.

[Class 18] Padded box lids are made by positioning padding between a selected part of the area of the lid top and a wrap sheet and then adhesively securing the sheet to the parts of the top not occupied by padding and the edges of the sheet to the side wall of the lid. The edges of the wrap sheet may be slit and the tab portions so formed secured to the side wall of the box, in overlapping relationship, and the edge of the sheet may be covered by a wrap strip secured around the side wall. The lid may be of any desired contour and, as shown, a heartshaped lid is formed from a top 103, Fig. 2, a side wall 102, Fig. 1, and a wrap sheet 101, Fig. 3, which is slit at the edges to form tabs 12 ; the lid may be formed in a machine such as described in Specification 419,741, a heartshaped form block 40, Fig. 7, being attached to the plunger 26 and co-operating with a recessed lower form block 50.

Title: Fuel injection systems for spark-ignition internal combustion engines
Inventor: SWATMAN PETER PHILLIMORE
IPC: F02M69/22
Filed: 1965-03-13
Abstract: 1,066,721. Regulating I.C. engines. S.U. CARBURETTER CO. Ltd. Feb.24, 1966 [March 13, 1965; June 10, 1965], Nos.10741/65 and 24511/65. Heading F1B. In a spark ignition fuel injection engine the pressure differential across a fuel metering jet is modulated when a transient pressure charge occurs in the region between the choke and the throttle valve and the fuel supply is stopped when an abnormally high depression occurs in the air inlet manifold. Air enters via a variable choke 40 and passes through a valve 7 to manifold 1 which feeds inductor ports 3, 4, 5, 6 each of which is supplied by a fuel injection nozzle 8. Fuel from a liquid pump (not shown) passes through pipe 10, deaerator 9 and valve 18 to the primary chamber 12 of a pressure control unit 11. Diaphragm 14, which is loaded pneumatically with or without spring assistance, according to the pressure in region 15 acts through sliding spindle 17 to control valve 18 thereby maintaining a constant pressure difference between chambers 12, 13. Fuel passes through pipe 21 to a fuel metering jet 19 and thence via a pipe 20 to secondary chamber 13, pipe 22 and flow divider 23. The action of diaphragm 14 maintains a substantially constant pressure drop across the fuel metering jet 19. From the flow divider, which has an air vent 25 and a spring-loaded plunger 26, fuel is delivered through pipes 27, 28, 29, 30 to nozzles 8 each of which has a needle valve 31 mounted on an adjustably spring-loaded diaphragm 32. The outer side of diaphragm 32 is subjected to ambient pressure. The countoured needle 36 is moved by a suction-operated member 37 that controls the effective cross-sectioned area of choke 16 so as to maintain a substantially constant air flow. A transient pressure drop in region 15 e.g. on sudden opening of throttle 7, is communicated via a pipe containing a restrictor 50 to chamber 49 to increase the load applied by diaphragm 51 through pin 52 on diaphragm 14. A greater pressuredifferential is momentarily established between chambers 12, 13 and likewise across jet 19 thereby temporarily increasing fuel flow. To counteract the effect of pulsations when throttle 7 is fully opened a connection 46, 47 containing a restrictor 48 is arranged between manifold 1 and chamber 49. When an abnormally high pressure occurs in manifold 1 e.g. during overrun, the pressure is communicated through pipe 46 to act on a snapaction diaphragm 58 which actuates a pivoted lever 60 to close fuel admission valve 18. A sealed temperature/pressure responsive capsule 62 is linked through link 65 and rod 17 to diaphragm 14 to effect compensation for varying temperature and/or pressure.
