Appl. No.:

12/868587

Inventors:

Kenneth C. Adkins - Mason OH, US

Assignee:

Summit Microelectronics, Inc. - San Diego CA

International Classification:

G05F 1/10

US Classification:

327536

Abstract:

Embodiments of the present invention include charge pump circuits and methods. In one embodiment, a first charge pump receives a voltage and generates a first charge pump output voltage and current for supplying the power requirements of a circuit. A second charge pump is coupled in series with the first charge pump. The second charge pump generates a second charge pump output voltage and current for supplying different power requirements of the circuit. In one embodiment, the first charge pump provides a high current low voltage output to a first circuit and the second charge pump provides a low current high voltage output to a second circuit. Capacitors of the first charge pump may be external to an integrated circuit and capacitors of the second charge pump may be internal to the integrated circuit.

Appl. No.:

09/800563

Inventors:

Thomas O'Brien - Cincinnati OH, US

International Classification:

G06F015/00

US Classification:

707/505000

Abstract:

According to the invention, a list of question words is presented to the user. The user then selects a question word and transmits the selection to the system. The system then generates a list of question syntax forms associated with the selected question word and presents this list of question syntax forms to the user. Each question syntax form has one or more terms missing from the question. The system acquires from the user the identity of a question syntax form from the list of question syntax forms and data for combining with the identified question syntax form to construct the user's complete question. The system then searches an electronic database for an answer to the question and transmits this information to the user in response to the user's question.
