Filed: 2003-02-21
Abstract: A method of forming a fuel tank (10 see fig 1) comprises forming a polymeric structural layer 34 to which a first polymeric barrier layer 30 is applied which is less permeable to hydrocarbons. The fuel tank (10) typically comprises a second polymeric barrier layer 40 such as polyvinylidene chloride which is solvent soluble and is also less permeable than the structural layer 34. A further structural layer 33 may be provided on the inside of the tank (10).

Title: Solar-powered battery charging
Inventor: KUESTER STEPHEN MICHAEL
IPC: H02J7/00
Filed: 2003-03-17
Abstract: A solar panel 4 of a battery charger supplies charging current alternately to two battery-charging stations 11 or 14 within the charger-casing 1, during a recurrent operating cycle in which one battery is charged while the open-circuit voltage of the other is monitored during successive periods of the cycle controlled by a microprocessor 25 of a circuit-panel 17. Charging current is supplied to the batteries via respective transistors 27,28, only one of which is ON at any time and is pulsed OFF and ON for regulating the average rate of charging if the output of the solar panel 4 exceeds an optimum magnitude, or for trickle charging the relevant battery if its monitored open-circuit voltage indicates it to be fully charged. Flashing LED indicators 20,21 show charge conditions and charge-rate of the respective batteries, and guides optimisation of orientation of the casing 1 for fastest charge. Charging stations 11 for two AA batteries are transverse to the stations 14 for two AAA batteries so only one battery-type can be charged at a time.

Each wiring level includes conductive metallization (e.g., metal-plated vias, conductive wiring lines, etc.) embedded in insulative material. The battery (420) is formed during BEOL integration within one or more wiring levels, and the conductive metallization (432,434,442,444) conductively couples positive (424) and negative (422) terminals of the battery to the electronic devices (900). The battery (420) may have several different topologies relative to the structural and geometrical relationships among the battery electrodes and electrolyte. Multiple batteries may be formed within one or more wiring levels, and may be conductively coupled to the electronic devices. The multiple batteries may be connected in series or in parallel.

Title: System and method for fabricating bragg gratings
Inventor: SAHLGREN BENGT
IPC: G02B6/34
Filed: 2002-03-06
Abstract: A novel method based on sequential writing for fabricating of advanced fiber Bragg gratings is disclosed.
