Abstract: A pattern is determined of the neck movement of a subject. The head/body movement of the subject is recorded with markers placed on the shoulders and on the head and thus moving with the subject. The locus curve of each marker in three-dimensional space is then determined in dependence on the time and it is stored as a data set. The neck movement is isolated from the head and torso movements by determining the difference between the average of the two locus curves that represent the shoulder movements and the locus curve representing the head movement. The pattern of movement established on the cranio-corpo-graphy is evaluated and analyzed using a data-processing device. The method is particularly suitable for determining the presence and the severity of an injury to the cervical spine as a result of whiplash caused by a traffic accident.

Abstract: A proportional oxygen sensor, a three-way catalyst, a binary O2 sensor, a NOx purification device, and a binary O2 sensor are positioned in the named order in the exhaust system of an internal combustion engine. A correction coefficient KMON2, which is set in accordance with the degree of deterioration of a three-way catalyst, is used to correct the timer value tmMON2 used to measure the time extending from the time at which the output of the O2 sensor is changed when the air-fuel ratio is increased, until the time at which the output of the O2 sensor is changed. When the corrected timer value tmMON2 is smaller than a reference time TNOxREF, it is ascertained that deterioration of the NOx purification device has occurred.

Abstract: The present invention deals with determining the level of fluid in a container. Typically, a beverage container containing a liquid will absorb heat energy from the surrounding environment at a greater rate than a gaseous component in the headspace of the beverage container. Thus, as the liquid is drawn from a beverage container a greater headspace results. If a thermometric measuring device is employed along the height of the beverage container the volume may be determined by observing the difference in the temperature along the height of the beverage container. In practice, a beer keg may exhibit a difference of as much as 9 degrees Fahrenheit on the exterior surface of the beer keg when measured at the headspace as opposed to the area where the liquid is present in the beverage container.

Abstract: A liquid level sensor is used on a sealed container comprises a heat source bonded to the container, a first temperature sensor mounted on the container adjacent the heat source, and a second temperature sensor mounted on the container spaced from the heat source. The temperatures at the first and second temperature sensors are sensed while the heat source is operating, and the differential in the temperatures is measured and used to control power to the heater. Changes in the differential in temperature between the first and second temperature sensors indicates when the heat conductivity between the first and second temperature sensors changes, due to presence or absence of a liquid in the container at the level of the temperature sensors.

Abstract: A wireless (e.g., radio) system and method for automatic water level maintenance of, e.g., a swimming pool utilizing capacitive liquid level sensing. A reference electrode allows water level sensing independent of the water chemistry or temperature. Capacitive electrodes having areas larger than the reference electrode sense various liquid levels when the liquid covers an area of any sensing electrode equal to the area of the reference electrode. Averaging is incorporated to filter out effects of wind or other disturbances. Upon sensing a given condition, the transmitter transmits a sensed condition to a remote receiver for control of valves and pumps for changing the water level in the pool. The receiver includes safety timers for filling and emptying to protect against equipment failure or communications faults. User selectable identification allows identical such radio systems to operate within proximity to each other. Power saving features are used to extend battery life.

Abstract: A pressure monitoring system comprises a first chamber (11) and a second chamber (12) separated by a diaphragm. The diaphragm carries respective SAW devices on the respective sides thereof, the SAW devices having different resonant frequencies. Variations in pressure within the second chamber (12) relative to the pressure within the first chamber (11) will cause deflection of the diaphragm and the resulting changes in resonant frequency of the SAW devices can be analyzed to indicate the pressure differential between the chambers. As illustrated, the pressure-measuring device is incorporated within a valve assembly for a vehicle tire. When the vehicle tire is inflated the inflation pressure is trapped within the first chamber (11) as a reference. Any subsequent loss of pressure from the second chamber (12), e.g. as a result of a puncture, will cause deflection of the diaphragm and a corresponding output from the SAW devices.
