Filed:

Dec 23, 2002

Appl. No.:

10/329102

Inventors:

David J. Bartek - Frisco TX, US

Assignee:

Microtune (San Diego), Inc. - San Diego CA

International Classification:

G06F015/16
H04B001/69

US Classification:

709217, 709227, 375130

Abstract:

A method for emulating a physical connection using a wireless connection includes establishing a communication connection with a host controller according to a first communication protocol and establishing a wireless connection with a wireless device coupled to a peripheral. The method further includes receiving a wireless signal comprising registration information for the peripheral formatted according to a second communication protocol and communicating the registration information to the host controller using the communication connection. The communication of the registration information to the host controller allows the host controller to recognize the peripheral.

US Classification:

709217, 709227

Abstract:

A method for emulating a physical connection using a wireless connection includes establishing a communication connection with a peripheral according to a communication protocol using a host controller. The method further includes receiving a wireless signal carrying data having a format specified by the communication protocol, extracting the data from the wireless signal, and communicating the data to the peripheral using the communication connection.

Appl. No.:

9/354356

Inventors:

Jukka-Pekka Neitiniemi - Irving TX
Kim A. Tran - Garland TX

Assignee:

Nokia Telecommunications Oy - Espoo

International Classification:

H01P 122
H03G 1102

US Classification:

333 171

Abstract:

A temperature compensated variable attenuator comprising a variable attenuator having at least one diode with temperature variations across the at least one diode producing a temperature offset signal. A bias source coupled to the variable attenuator supplies a biasing signal to the at least one diode through a temperature compensation source. The temperature compensation source is coupled between the bias source and the variable attenuator with the temperature compensation source comprising at least one diode capable of producing a temperature offset signal approximately equivalent to the temperature offset signal produced by the first at least one diode. The approximate temperature offset signal subtracted from the biasing signal produces a temperature compensated bias signal that is supplied to the variable attenuator.
