    摘要: 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. The internal watchdog timer (WDT) monitors the deep sleep counter and when the deep sleep counter, for example, contains a NULL value (all zeroes) the WDT wakes up the microcontroller (i.e., the WDT initiates the low-speed clock so that the tag cannot enter the lucid sleep mode). The tire tag delivers data at a slower or faster rate to achieve the important advantage of extending battery life. Also to extend battery life two oscillators are desirable because they allow two clock speeds. Having two clocks allows a designer to minimize use of the high-speed clock, thus conserving battery power.

    摘要: A water temperature control system for achieving one of a plurality of wash water temperatures for a washing machine having a hot water valve, a cold water valve and an inlet conduit for carrying a combined supply of water from the hot and cold water valves to a wash bath. If a WARM FILL option is selected by the user, the cold water valve is continuously energized thereby maintaining the valve in an open condition and a normally closed temperature responsive switch is connected in series with the hot water valve. The normally closed temperature responsive switch has a predetermined temperature set point and is located on the inlet conduit. The normally closed temperature responsive switch operates to cycle the hot water valve on and off to control the inlet wash water temperature at or below the first preselected set point. If a HOT FILL option is selected, the hot water valve is continuously energized and a normally open temperature responsive switch is connected in series with the cold water valve. The normally open temperature responsive switch has a predetermined temperature set point and is located on the inlet conduit. The normally open temperature responsive switch operates to cycle the cold water valve on and off to control the inlet wash water temperature to at or below the second preselected set point.

    摘要: 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. In one embodiment, the device is a tire tag mounted inside a tire that measures tire data and transmits that data to a remote source in response to an interrogation request, an alert condition, or automatically on a periodic basis.
