    摘要： The invention provides a method for cycle-by-cycle control of a LED current (ILED) flowing through a LED circuit arrangement (LEDCIRC) at a mean LED current level. The method comprises a) establishing a converter current (IL), b) establishing an oscillation of the converter current (IL) between substantially a valley current level and substantially a peak current level, c) feeding the LED circuit arrangement (LEDCIRC) with the converter current (IL) as the LED current during a part of an oscillation cycle of the oscillation of the converter current, d) determining a current level correction for compensating a current level error between an integral over an oscillation cycle of the LED current and a reference, the reference being representative of the mean LED current level, and e) adjusting at least one of the valley current level and the peak current level with the current level correction for use in a successive cycle of the oscillation of the converter current. The invention also provides a circuit arrangement operable for using the method, a LED driver IC using the circuit arrangement, a circuit composition with at least one LED and the circuit arrangement, and a lighting system with the circuit composition.

    摘要： Metal-containing colloids are manufactured by reacting a plurality of metal ions and a plurality of organic agent molecules to form metal complexes in a mixture having a pH greater than about 4.25. The metal complexes are reduced for at least 0.5 hour to form stable colloidal nanoparticles. The extended reduction time improves the stability of the colloidal particles as compared to shorter reduction times. The stability of the colloidal particles allows for colloids with higher concentrations of metal to be formed. The concentration of metal in the colloid is preferably at least about 150 ppm by weight.

    摘要： A group-browsing system for a plurality of clients each including a shared web browser. A server is linked to the shared web browser of each client and is configured to monitor the transmission of the web site URL request from the shared web browser of one client of the group and to direct the request to the shared web browser of other clients in the group. A gatekeeper module is configured to first mask the identity of each client's computer on the shared browser. This prevents the web site from retrieving any client's actual identifier. Second, the gatekeeper is also configured to create a same temporary identifier for each client when any client logs on to the web site so that the same web page is displayed for all the clients in the group.
