Abstract: A driving assistance device that detects an object around the own vehicle by using an ultrasonic sensor mounted on the own vehicle and performs driving assistance control of the own vehicle. The driving assistance device drives an oscillator of the ultrasonic sensor so that ultrasonic waves are transmitted from the oscillator. The driving assistance device acquires a duration and a frequency of reverberation occurring in association with driving of the oscillator. The driving assistance device determines, on a basis of the acquired duration and frequency of the reverberation, whether an oscillation characteristic of the reverberation has changed. The driving assistance device changes, on a basis of a result of determination of the oscillation characteristic of the reverberation, at least one execution mode of the driving assistance control and determination of abnormality in the driving assistance control.

Abstract: A computer includes a processor that is programmed to identify, in a first vehicle, a second vehicle based on first vehicle sensor data. The processor is programmed to determine, based on at least one of the sensor data and additional environmental data, a risk of ice from the second vehicle striking the first vehicle. The processor is further programmed to cause an action in the first vehicle based on the determined risk.

Abstract: A recovery phenomenon in which the concentration of a compound to be measured in soil increases again after reducing the concentration is utilized for changing the distribution state of the compound to be measured in soil, whereby the direction of the high-concentration region of the compound to be measured in soil can be detected.

Abstract: A monitor for remote reading of liquid volumes in pressurized tanks utilizes a hollow buoyant displacement probe extending downwardly from a load cell carried adjacent a top port in the tank. The buoyant probe is optionally formed in detachable segments so that it can be assembled on site at the time of installation. The load cell is suspended from a flange cover acting as a closure for the tank port so that the load cell is freely pivotable on perpendicular horizontal axes, insuring that it is always oriented horizontally. A temperature-reading string is positioned in the open hollow center of the probe and has three spaced temperature sensing units along its length.

A temperature-reading string is positioned in the open hollow center of the probe and has three spaced temperature sensing units along its length. Force data from the load cell, giving the apparent weight of the probe immersed in the liquid tank contents, and temperature data, from which volumetric data may be calculated, are fed to an external battery-operated microprocessor which periodically radios its data to a central computer which may be polled by phone lines from a remote monitoring station.

Abstract: An obstacle detecting system for vehicles has an ultrasonic vibrator having a vibration plate and mounted on a vehicle to transmit and receive an ultrasonic wave. An obstacle is detected in response to an output signal of the ultrasonic vibrator. When the temperature around the ultrasonic vibrator is below a predetermined temperature corresponding to snowfall, the system calculates a ratio of a period of reverberating vibration of the ultrasonic vibrator relative to a predetermined time period following an ultrasonic wave transmission, and determines accumulation of snow when the calculated ratio exceeds a predetermined time ratio. The system notifies an abnormality of the ultrasonic vibrator arising from the accumulation of snow.

Abstract: A liquid aspiration method which includes a method for determining the quality of the aspirated sample through mathematical analysis of the pressure profile generated before, during, and after the aspiration process and comparison of the results with predetermined known values.

Abstract: An apparatus which permits continuous automatic determination of the bulk specific gravity of a powdery sample and highly precise measurement thereof. The apparatus comprises a robot 3 transporting a container 2 filled with a powdery sample; a funnel 4 provided with a damper, which receives the powdery sample discharged from the container 2; a damper-driving unit 5a for pulling out and pushing the damper 5; a sample sensor 7 for detecting the powdery sample dropped through the funnel 4 provided with a damper; a constant volume receiver 6 for receiving dropped through the funnel 4 provided with a damper; a scraping bar 8 for sliding the upper face of the constant volume receiver 6; a scraping bar-driving unit 8a for reciprocating the scraping bar 8; a constant volume receiver-conveying robot 21 transporting the constant volume receiver 6; an electronic balance 22 which determines the weight the powdery sample in the constant volume receiver 6; and a cleaner 23 for aspirating the weighed powdery sample.

Abstract: The measuring device has bobs 10, 17 suspended from a weight 12 with wires 11, 16. The hook 13 of the weight 12 is hung from a suspensor thread 15 extending downwards from a balance 14. The weight 12 may be omitted by using the upper bob 10 for dead weight. The bobs 10, 17 and the wires 11, 16 may be coated with a coating layer unreactive to the melt 19 whose density is to be measured. The weights of the measuring device is measured by the balance 14 under the first condition that the lower bob 17 is immersed in the liquid 19 and the second condition that the bobs 10, 17 are both immersed in the liquid 19. The density of the liquid 19 is calculated from the two measured values without the influence of the surface tension of the liquid 19 applied to the wires 11, 16.

Abstract: The invention relates to an apparatus for measuring products, including at least one hopper for feeding the product, at least one cell intended to receive the product and provided with a means for opening and closing for arbitrary evacuation of the product after measurement, and a weighing sensor.

Abstract: A density measuring apparatus (densitometer) useful for rapid absolute determination of the density, the temperature dependence of density, partial volume and thermal expansivity of condensed matter, based on the hydrostatic method, employs an electronic balance enclosed in an airtight envelope which forms a weighing chamber and a measuring chamber. The balance comprises a balance beam and measuring and weighing hangdown assemblies attached to opposite ends of the beam. The balance beam and the weighing hangdown assembly are positioned in the weighing chamber. The measuring hangdown assembly extends from the weighing chamber into the measuring chamber and comprises a thin suspension wire and a sample support or a sinker which are positioned in a multi-jacket measuring vessel adapted to receive a buoyant or sample liquid. A vapor barrier is provided between the weighing and measuring chambers to prevent vapors of the buoyant or sample liquid from flowing into the weighing chamber.
