Patent number: 8266465Abstract: A battery operated device includes a receiver for receiving a transmission that includes a postamble. A sensor, in a tire, measures a parameter of the tire and outputs data indicative of the parameter. A microprocessor is coupled to the receiver and the sensor. The microprocessor is configured to periodically partially awaken to determine whether the transmission is likely a forward link packet (FLP) by examining the postamble, and to transmit the data in a reverse link packet (RLP) in response to confirming that the transmission is a FLP.Type: GrantFiled: March 7, 2012Date of Patent: September 11, 2012Assignee: Bridgestone Americas Tire Operation, LLCInventors: Gordon E. Hardman, John W. Pyne, Molly A. Hardman, David A. Przygocki, David M. Coombs, Paul B. Wilson, Ronald C. Grush, Philip B. Loudin, Brett W. Floyd

Publication number: 20120187952Abstract: An array of capacitor plates is disclosed wherein each plate is the foundation on which a page of printed material is built. Capacitance is sequentially detected between nearby pages to determine where capacitive interaction fails, thus determining the page opening. Any number of pages can be scanned in this manner without the use of buttons, switches or pointing devices. Page openings can be determined to provide automatic audible narration that is pertinent to the contents of each page, even when randomly opened.Type: ApplicationFiled: January 22, 2011Publication date: July 26, 2012Inventor: David M. Coombs

Patent number: 7739529Abstract: A system for conserving battery life in a battery operated device such as a tire tag where there are several modes of operation. The typical mode is the deep sleep mode where the tag is generally inactive (no clock is running; however, an RC watchdog timer is running, which uses very little power). The tag spends most of its time in this low power mode. The tag periodically partially awakens to a lucid sleep mode (when the watchdog timer times out), initiates a low-speed clock, determines if it is time to enter a search mode by examining a search mode counter and, if it is not time, adjusts the search mode counter (e.g., decrements the counter by one), and returns to the deep sleep mode. The tag sleeps in the deep sleep mode most of its life in an effort to conserve battery power. During the deep sleep mode, because the clock oscillators are OFF, a deep sleep counter is adjusted (incremented or decremented) periodically (e.g., about every 18 ms) by an internal R/C oscillator.Type: GrantFiled: November 29, 2006Date of Patent: June 15, 2010Inventors: Gordon E.

Patent number: 7161476Abstract: An electronic tire maintenance system is provided for measuring a parameter of a device at a first location. The system includes a sensor for measuring the device parameter and generating a data signal representing the measured parameter. The system also includes a microprocessor coupled to the sensor for activating the sensor on a first periodic basis to measure the device parameter. The microprocessor includes a memory for storing the generated data signal representing the measured parameter. A transmitter and a receiver are coupled to the microprocessor. The microprocessor periodically partially awakens to determine, on a second periodic basis, if a received transmission is a valid interrogation signal and, if so, fully awakens and responds to the valid interrogation signal, via the transmitter, by at least transmitting the last stored measured parameter.Type: GrantFiled: July 26, 2001Date of Patent: January 9, 2007Assignee: Bridgestone Firestone North American Tire, LLCInventors: Gordon E.
