Resistive Heating Using Polyaniline Fiber
View pageUS Patent:
7132630, Nov 7, 2006
Filed:
Dec 2, 2003
Appl. No.:
10/727025
Inventors:
Baohua Qi - Albuquerque NM, US
Benjamin R. Mattes - Santa Fe NM, US
Benjamin R. Mattes - Santa Fe NM, US
Assignee:
Sante Fe Science and Technology, LLC - Santa Fe NM
International Classification:
H05B 3/54
US Classification:
219545, 219529, 219544, 428480, 264103
Abstract:
The use of conductive polyaniline fibers for resistive heating applications is described. Unlike metal wires and conductive-polymer coated fibers, under certain conditions, electric voltages or currents used to generate heat in the fibers were found to produce irreversible changes to the polymer backbone that destroy its electrical conductivity but not its structural integrity. The temperature that these changes occur varies with dopant and fiber diameter, and can be tailored to specific applications. Since these changes occur at lower temperatures than the temperature at which dopant molecules within the conductive polymer are lost or decomposed, both of which lower the conductivity of the material, polyaniline fibers can be used for resistive heating applications where the heating element is in the vicinity of the skin of the wearer thereof.

Fingerprint Sensing Device Using Pulse Processing
View pageUS Patent:
7965877, Jun 21, 2011
Filed:
Oct 20, 2006
Appl. No.:
11/584165
Inventors:
Baohua Qi - Columbus IN, US
International Classification:
G06K 9/20
US Classification:
382124
Abstract:
A fingerprint sensing device that measures the capacitance between an array of electrode plates and finger skin using pulse processing, in which pulse width rather than voltage level, is used for capacitance measurement and digital signal conversion. A pulse, the width of which is compared and adjusted with that of a reference pulse, is generated when voltage at sensing electrodes in discharging is compared with a reference voltage. The comparison results are then digitalized in a grade image sensor or output directly in a binary image sensor. The sensor can communicate with a CPU using serial communication, parallel communication, or memory map scheme. Since no A/D is used, there is no extra time and hardware cost for the conversion from analog signals to digital signals. Due to the pulse processing nature, the circuits can be configured insensitive to the change or fluctuation in voltage supply. This feature enables the sensing device work with a variety of voltages, and thus it can be better used in portable, battery powered or passive devices.
Rfid Sensor Using Pulse Processing
View pageUS Patent:
8013714, Sep 6, 2011
Filed:
Mar 24, 2007
Appl. No.:
11/728137
Inventors:
Baohua Qi - Columbus IN, US
International Classification:
H04Q 5/22
US Classification:
340 101, 340 103, 34053926, 3405721, 340445, 380 37
Abstract:
A radio frequency identification device having sensing elements incorporated in its tags, and the sensing value determines the width of a sensing pulse in its RFID code. Through a pulse-processing unit, during communication, digital sensing values are obtained by measuring the width of the sensing pulse. Since only discrete signals exist, the tag device is insensitive to the fluctuation in its power supply voltage, which is derived from a continuous wave RF carrier.
Rfid Sensor Device Based On Pulse-Processing
View pageUS Patent:
8018323, Sep 13, 2011
Filed:
Jan 27, 2007
Appl. No.:
11/699232
Inventors:
Baohua Qi - Columbus IN, US
International Classification:
H04Q 5/22
US Classification:
340 104, 340 101, 340 103, 340445, 34053926, 3405721, 380 37
Abstract:
A radio frequency identification device having sensing elements incorporated in the clock generators of its tags, which generate a leading code and an identification code. In the interrogator, the leading code is detected and its pulse width is measured for calculating sensing values and the baud rate in receiving the identification code. No analog to digital converter is needed in digitizing sensing values and only discrete signals exist in sensing signal generation and communication. The tag device is insensitive to variations in its power supply voltage obtained from a continuous wave RF carrier.
Rfid Sensor Array And Sensor Group Based On Pulse-Processing
View pageUS Patent:
8026795, Sep 27, 2011
Filed:
Feb 20, 2008
Appl. No.:
12/070665
Inventors:
Baohua Qi - Columbus IN, US
International Classification:
H04Q 5/22
US Classification:
340 101, 340 103, 34053926, 3405721, 340445, 380 37
Abstract:
An RFID device having sensor arrays incorporated in its tags. Each tag generates an ID code together with sensing pulses the width of which changes with sensing values. Conflicts between tags in communication are avoided by adding a sleep section to the code sequence. The interrogator reads the ID code and digitizes the width of sensing pulses during the communication with tags, and then calculates sensing values based on the information obtained. Since only discrete signals exist in data acquisition, and the digitization process is in parallel with data communication, the system needs neither ADC circuits nor an extra process for signal digitization.
