View page
US Patent:
6556046, Apr 29, 2003
Filed:
Sep 14, 2001
Appl. No.:
09/953059
Inventors:
Roger D. St. Amand - Tempe AZ
Steven R. Bible - Chandler AZ
Richard J. Fisher - Glendale AZ
Johannes A. Van Niekerk - Tempe AZ
Farron L. Dacus - Chandler AZ
Assignee:
Microchip Technology Incorporated - Chandler AZ
International Classification:
H03K 190175
US Classification:
326 63, 327333
Abstract:
The present invention relates generally to functional pathway configurations at the interfaces between integrated circuits (ICs) and the circuit assemblies with which the ICs communicate. More particularly, the present invention relates generally to the functional pathway configuration at the interface between a digital device and a radio frequency device (wireless RF digital device), and the circuitry of a system including the packaged devices. Even more particularly, the present invention relates to a wireless radio frequency digital device functional pathway configuration for the interface between the wireless radio frequency digital device and a system in which the wireless radio frequency digital device is embedded.

Methods And Apparatus For Adjusting Dc Power Consumption In Mobile Handset

View page
US Patent:
6633750, Oct 14, 2003
Filed:
Sep 10, 1999
Appl. No.:
09/393508
Inventors:
Farron L. Dacus - Irving TX
Russell A. Morris - Keller TX
Assignee:
Intel Corporation - Santa Clara CA
International Classification:
H04Q 720
US Classification:
455126, 455127, 455 69, 455115, 455343
Abstract:
Apparatus and methods are provided for regulating the power consumption within a wireless communications mobile handset. A base station transmits an RF power output designating signal that indicates a desired level of the RF power output from the mobile handset. The mobile handset receives the RF power output designating signal, where it is used to set the level of the DC power supplied to the mobile handset. In this manner, the minimum amount of power necessary to maintain linear operation of the mobile handset is expended in the mobile handset. The DC power level is set by internally generating a control signal. The level of the control signal is dictated by the desired level of the RF power output as indicated by the received RF power output designating signal. The control signal is then applied to an RF amplifier circuit contained within the mobile handset to set the DC power level. The DC power level can be further varied from the set DC power level in proportion to an envelope of an RF input signal to provide a more power-efficient mobile handset.

Battery Assisted Rfid System Command Set

View page
US Patent:
8384523, Feb 26, 2013
Filed:
Sep 5, 2008
Appl. No.:
12/205745
Inventors:
Alfonso Rodriquez - Shady Shores TX, US
Farron Dacus - Dallas TX, US
Johannes Albertus van Niekerk - Dallas TX, US
Assignee:
Intelleflex Corporation - Santa Clara CA
International Classification:
H04Q 5/22
US Classification:
340 101, 340 103, 340 1034, 340 51
Abstract:
Specialized battery assisted command set design methods are disclosed that provide for interference rejection using highly sensitive but relatively broadband RFID tags. The command set design also supports RFID system RF power control for further interference control. The command set design also allows for convenient expansion to active transmitters and receivers in tags operating within the same system. Embodiments of the present invention provide RFID systems having battery-assisted, Semi-Passive RFID tags that operate with sensitive transistor based square law tag receivers utilizing a plurality of tag receiver dynamic range states. Embodiments of the present invention are also enhanced with receiver training and synchronizing methods suited to the high tag sensitivity and need for dynamic range state switching. These enhancements may employ pseudo-random sequence based receiver training, activation signaling, and frame synchronizing. Additional enhancement attained via power leveling methods that optimize the amount of transmitted power and interference from a reader in relation to the sensitivity of the RFID tags, their ranges from the reader, and the unique physics of the backscatter RFID radio link.

Battery Assisted Rfid System Rf Power Control And Interference Mitigation Methods

US Patent:
8410906, Apr 2, 2013
Filed:
Sep 5, 2008
Appl. No.:
12/205718
Inventors:
Farron Dacus - Dallas TX, US
Johannes Albertus van Niekerk - Dallas TX, US
Alfonso Rodriguez - Shady Shores TX, US
Assignee:
Intelleflex Corporation - Santa Clara CA
International Classification:
H04Q 5/22
US Classification:
340 101, 455 412
Abstract:
The present invention discloses battery assisted RFID system RF power leveling methods that optimize the amount of transmitted power and interference from a reader in relation to the sensitivity of the RFID tags, their ranges from the reader, and the unique physics of the backscatter RFID radio link. These methods enhance system reliability when employing battery assisted RFID tags that operate with sensitive transistor based square law tag receivers and highly sensitive RFID readers intended to take advantage of outstanding tag sensitivity. Further enhancement is achieved via design of system command sets and tag state machine behavior that optimally support the power level operations, power level operations that span across tag hibernation and normal modes, and that otherwise control system interference. Embodiments of the present invention are also enhanced with receiver training and synchronizing methods suited to the high tag sensitivity and need for dynamic range state switching. These enhancements may employ pseudo-random sequence based receiver training, activation signaling, and frame synchronizing.

US Patent:
8421598, Apr 16, 2013
Filed:
Jun 4, 2009
Appl. No.:
12/478672
Inventors:
Farron Dacus - Dallas TX, US
Johannes Albertus van Niekerk - Dallas TX, US
Alfonso Rodriguez - Shady Shores TX, US
Assignee:
Intelleflex Corporation - Santa Clara CA
International Classification:
H04Q 5/22
US Classification:
340 101, 455 412
Abstract:
The present invention discloses battery assisted RFID system RF power control implementations that optimize the amount of transmitted power and interference from a reader in relation to the sensitivity of the RFID tags, their ranges from the reader, and the unique physics of the backscatter RFID radio link. Tag transmit power control implementations are also disclosed. These methods enhance system reliability when employing battery assisted RFID tags that operate with sensitive transistor based square law tag receivers and highly sensitive RFID readers intended to take advantage of outstanding tag sensitivity. Further enhancement is achieved via implementation of specialized commands that optimally support the power control operations, otherwise control system interference, and allow maximum usage of high sensitivity in both tags and readers.

US Patent:
20030060185, Mar 27, 2003
Filed:
Sep 14, 2001
Appl. No.:
09/953058
Inventors:
Richard Fisher - Glendale AZ, US
Roger St. Amand - Tempe AZ, US
Steven Bible - Chandler AZ, US
Johannes Van Niekerk - Tempe AZ, US
Farron Dacus - Chandler AZ, US
International Classification:
H04B001/06
US Classification:
455/344000, 455/130000
Abstract:
A wireless control and/or data acquisition system in an integrated circuit comprises a digital device and a wireless device, e.g., a radio frequency (RF) device, an infrared device (IrDA), etc. A micro-electro-mechanical (MEM) device may also be included in the integrated circuit package. The MEM may be used as a sensor, non-volatile memory, a filter, a frequency determining resonator, and/or a control device in combination with the digital device. The digital device and RF device may have independent power and signal connections for signal isolation between the digital device and RF device. Standby and sleep modes for the digital device and RF device reduce power consumption and low voltage operation enables the use of a simple battery power source.
