Title: Apparatus and method for simulating a battery tester with a fixed resistance load
Inventor: KLANG JAMES K
IPC: G01R31/36
Filed: 2004-10-15
Abstract: A method and apparatus for simulating a battery tester with a fixed resistance load, such as a widely used Japanese load tester that rates the strength of Japanese batteries that are categorized under the Japanese Industrial Standard (JIS), are provided. This invention simulates such a device without invoking large current loads, yields familiar results, utilizes an existing database and provides more conclusive testing. The method includes measuring an open circuit voltage (OCV), temperature and a dynamic parameter of the battery. A load voltage of the battery is estimated as a function of the measured battery dynamic parameter, the OCV, the load resistance value of the load tester and the battery temperature. A bounce-back voltage or recovery voltage is then predicted using the temperature and the open circuit voltage. The dynamic parameter is preferably the measured conductance or resistance of the battery in response to an applied current pulse. The strength of the battery can thus be rated.

The linkages may overlap each other when retracted; and may move in opposite directions during retraction. The actuator may be a single hydraulic cylinder for each axle; and may be pivoted to the vehicle chassis. A lock may be provided to lock the suspension in the retracted position.

Title: Bearing adjustment
Inventor: SPARROW ROGER LIONEL DAVID
IPC: B62K21/06
Filed: 2003-10-02
Abstract: An adjuster for an upper bearing (11,12) of the front forks of a bicycle has two thrust rings (122,123). The lower one (122) has a lower, planar, radially-extending, thrust surface (124), a bore (125) which is a sliding fit on the steerer, and an upper, external, male, 45{ conical surface (126). The upper thrust ring (123) has a lower, complementary internal and female, 45{ conical surface (128) and a planar, radially extending upper thrust surface (129). The stem (6) has a thrust surface (31) complementary to the upper surface (129) and the compression ring has a similarly complementary thrust surface (32). The lower thrust ring is radially split (141) and has a threaded bore (142) intercepting this split perpendicularly. A grub screw (143) is received in the bore (142). With the steering assembly loosely fitted together, the grub screw (143) released, and the thrust rings resting on the compression ring (15), the stem is pressed down on top of the thrust rings. A stem (6) is then clamped to the steerer (3). There will be vertical play in the bearings. The grub screw is tightened to abut the opposite face (144) of the split (141), to urge the lower thrust ring to increase in diameter. Its conical surface reacts against that of the upper thrust ring, driving the two apart axially of the steerer to drive the compression ring into the tapered bore (14) of the upper race, centring the race on the steerer and taking up the play in the bearings.

Title: Liquid fuel gasifying and fuel-air mixing system for internal combustion engines
Inventor: KYRIACOU COSTAS SAVVA
IPC: F02M31/18
Filed: 2006-04-21
Abstract: A system for gasifying or vaporising liquid fuel, including petrol, diesel and kerosene, for supplying an i.c. engine comprises a number of Power Units, eg four as shown, each having an intake air passage carrying air past a fuel nozzle and carrying the fuel and air to the cylinders or the engine. Heat exchange takes place during operation of the system because the evaporation of fuel needs a certain amount of latent heat. As an example, six Power Units may be provided, three of which operate with a first throttle and, for full acceleration, a further three with a second throttle. The system allows gasified fuel to mix properly with air, thus providing the best conditions for combustion and therefore reducing fuel consumption and emissions. The system is simple and may replace an existing carburetor or fuel injection system.

Title: Lattice reduction aided decoding in wireless MIMO receivers
Inventor: PONNAMPALAM VISHAKAN
IPC: H03M13/45
Filed: 2006-09-01
Abstract: In a wireless Multiple Input Multiple Output (MIMO) receiver of Space Time Block Coded (STBC) data via several antennas 27, a lattice reduction aided decoder 30 outputs a list of likely candidate soft-decision estimates c of transmitted bits <B>x</B> by taking into account the varying reliability of the quantised detected values ^z due to different amounts of noise <B>n</B> being present in the un-quantised values < ><B>z</B>. A channel matrix <B>H</B> (estimated from pilot signals) is "reduced" by eg. a LLL algorithm to a more quasi-orthogonal matrix < ><B>H</B> having shorter base vectors, yielding transmitted bit estimates < ><B>z</B> from a received signal <B>y</B>. These are then quantised by generating a list of the (weighted squared Euclidian) nearest candidate vectors to < ><B>z</B> via k shortest path algorithms (230, fig.5). Each candidate vector <B>c</B> is then mapped to a corresponding signal vector <B>x</B> (240, fig. 5), and the constellation checked to ensure that all such signal vectors are valid possibilities, the most likely list being that which contains the most valid constellation points. Probabilities for each valid point are then calculated (250-270, fig. 5).

Filed: 2006-12-01
Abstract: The invention addresses the problem of limited processing power on smart cards by securely delegating some of the processing burden to a host processing apparatus which is operable in a secure domain. The smart card includes authentication logic operable when connected to the host processing apparatus to determine whether a secure data processing domain having predetermined properties is present within the host and, in response to identifying a suitable secure data processing domain, the smart card delegates at least some data processing operations to be processed within the secure domain. Faster processing is achieved than would otherwise be possible on the smart card alone. The smart card may transmit an application to the host for processing in the secure domain and may transmit scheduling signals to control delegated processing operations. The smart card may comprise an application programming interface (API) implementation. A system comprising the smart card and the host may be a mobile phone or set top box.
