Title: Method and apparatus for creating investment advice marketplace and for providing investment advice to multiple investors
Inventor: WALLMAN STEVEN M H
IPC: G06Q30/00
Filed: 2002-11-14
Abstract: A method for creating an electronic marketplace of investment advice for consumers, each of which are engaged in electronic portfolio trading of market tradable assets/liabilities enables advisors to each create a model portfolio of market tradable assets/liabilities and then disseminate the model portfolios to potential consumers. These model portfolios created by the advisors are disseminated as preset portfolios that can be purchased singly or in combination with each other by one or more consumers, a result of which can then be electronically traded as an entire portfolio of market tradable assets/liabilities by the one or more consumers. Along with each model portfolios a fee associated with each of the model portfolios is displayed. This fee is that which must be paid to the advisor that created the model portfolio upon selecting to purchase the model portfolio singly or in combination with one or more other model portfolios. Any fee associated with a particular model portfolio purchased by a consumer is deducted from funds allocated to the purchased portfolio and then forwarded to the respective advisor. The above method uses a computer-based portfolio manager system that enables a user to create and manage a portfolio of investments. Users can create multiple sub-portfolios, termed folios, within their overall investment portfolio. Each of these folios can be created by the user or selected from multiple preset folios. One of the possible preset folios includes a manager's recommended folio. This folio is regularly updated, thereby indicating buy and sell recommendations of the manager.

The second heat exhausting fin directly couples with the heat source and the heat pipe to catch another part of the heat. The second heat exhausting fins utilizes exhausted air of the first fan to transfer the another part of the heat to the second fan. The second fan further exhausts the another part of the heat to the outside of the equipment. The cooling apparatus further has a third exhausting fins and a second heat pipe. The second heat pipe transfers the heat to the exhausting fins more efficiently. The third exhausting fin positioned at an outlet of the second fan makes additional one time heat exchange to further enhance the cooling efficiency of the cooling apparatus.

Title: Buck/step-down direct-current/direct-current (DC/DC) converter and power converting method
Inventor: LIU HSING-FU
Filed: 2003-05-20
Abstract: The buck/step-down direct-current/direct-current (DC/DC) converter of the present invention includes two first switches and two step-down loops. The two first switches are arranged in parallel on a DC power and their close/open circuit conditions are opposite to each other but their close/open circuit durations are the same. One end of each step-down loop is connected with these two first switches separately and the other end of each step-down loop, consisting of a second switch, an inductor, and a capacitor, is connected in parallel with a load. The close/open circuit condition of the two-second switches is opposite to that of the connected first switch. Since the two first switches have the same close/open circuit duration but are opposite in close/open circuit condition, the DC power can generate a first pulse signal and a second pulse signal where the duty cycle of each pulse signal is 50 percent and the phase difference between the two pulse signals is 180 degree. Each of the two step-down loops can sense the first pulse signal and the second pulse signal and generate a first current and a second current separately before transmitting the currents to a load.
