US Patent:

8154389, Apr 10, 2012

Filed:

Apr 7, 2009

Appl. No.:

12/419326

Inventors:

Harry D. Rowland - East Peoria IL, US
Roger Dwight Watkins - Dunlap IL, US
Balamurugan Sundaram - Peoria IL, US

Assignee:

Endotronix, Inc. - Peoria IL

International Classification:

H04Q 5/22

US Classification:

340 132, 340 101, 340 103, 340 104, 340 1325

Abstract:

A wireless sensor reader is provided to interface with a wireless sensor. The wireless sensor reader transmits an excitation pulse to cause the wireless sensor to generate a ring signal. The wireless sensor reader receives and amplifies the ring signal and sends the signal to a phase-locked loop. A voltage-controlled oscillator in the phase-locked loop locks onto the ring signal frequency and generates a count signal at a frequency related to the ring signal frequency. The voltage-controlled oscillator is placed into a hold mode where the control voltage is maintained constant to allow the count signal frequency to be determined.

US Classification:

340 1325, 340 101, 340 103, 340 104

Abstract:

A wireless sensor reader is provided to interface with a wireless sensor. The wireless sensor reader transmits a narrowband, fixed frequency excitation pulse to cause the wireless sensor to generate a ring signal. The ring signal corresponds to the value of the physical parameter being sensed. The wireless sensor reader receives and amplifies the ring signal and sends the signal to a phase-locked loop. A voltage-controlled oscillator in the phase-locked loop locks onto the ring signal frequency and generates a count signal at a frequency related to the ring signal frequency. The voltage-controlled oscillator is placed into a hold mode where the control voltage is maintained constant to allow the count signal frequency to be determined. The low power, simple circuitry required to generate the excitation pulse allows the reader to be a small, battery operated unit. Alternative methods of frequency determination are also disclosed.

International Classification:

G01L 7/08
H01G 4/40

US Classification:

73715, 29 2541

Abstract:

A method for fabricating a wireless pressure sensor includes providing a first substrate. A portion of the first substrate is controllably displaced to form a cavity. A conducting material is patterned on the first substrate to form a first capacitor plate and a first inductor. A second substrate is provided. A conducting material is patterned on the second substrate to form a second capacitor plate. The second substrate is attached to the first substrate to seal the cavity such that at least a portion of the second substrate is movable with respect to the first substrate within the cavity in response to a change in an external condition. A hermetically sealed capacitive pressure sensor may reside in the cavity between the first substrate and second substrate.
