The present invention provides an acoustic vibration analyzing apparatus for carrying out acoustic vibration analysis by picking up data of sounds generated due to rotation of a plurality of gears and data of the number of revolutions of a gear selected from a plurality of gears when a transmission of a vehicle having the plurality of gears operates. The acoustic vibration analyzing apparatus comprises an acoustic vibration calculation portion for analyzing acoustic data in terms of frequency, an order calculation portion for calculating an order in compliance with the specifications of a plurality of gears, a speed calculation portion for calculating the speed of a vehicle, and a display unit for displaying acoustic pressure levels with the order and vehicle speed associated therewith.

Various corporate, industry, and regulatory guidelines, best practices and standards are used in establishing acceptable levels of accuracy for volume dimensioning systems used in commerce. A volume dimensioning system can determine at least one distortion value that is indicative of an amount of distortion present in the system and responsive to the amount of distortion, autonomously after or adjust the units of accuracy of information reported by the system. Such alteration or adjustment of units of accuracy may be performed based on an assessment of the distortion relative to a number of distortion thresholds. Responsive to the assessment, the volume dimensioning system can adjust a unit of accuracy in a representation of volume dimensioning related information.

Volume dimensioning employs techniques to reduce multipath reflection or return of illumination, and hence distortion. Volume dimensioning for any given target object includes a sequence of one or more illuminations and respective detections of returned illumination. A sequence typically includes illumination with at least one initial spatial illumination pattern and with one or more refined spatial illumination patterns. Refined spatial illumination patterns are generated based on previous illumination in order to reduce distortion. The number of refined spatial illumination patterns in a sequence may be fixed, or may vary based on results of prior illumination(s) in the sequence. Refined spatial illumination patterns may avoid illuminating background areas that contribute to distortion. Sometimes, illumination with the initial spatial illumination pattern may produce sufficiently acceptable results, and refined spatial illumination patterns in the sequence omitted.

A gas flow rate verification apparatus is provided for shared use in a multiple tool semiconductor processing platform. The gas flow rate verification apparatus is defined to measure a pressure rate of rise and temperature within a test volume for determination of a corresponding gas flow rate. The apparatus includes first and second volumes, wherein the second volume is larger than the first volume. The apparatus also includes first and second pressure measurement devices, wherein the second pressure measurement device is capable of measuring higher pressures. Based on the target gas flow rate to be measured, either the first or second volume can be selected as the test volume, and either the first or second pressure measurement device can be selected to measure the pressure in the test volume. Configurability of the apparatus enables accurate measurement of gas flow rates over a broad range and in an time efficient manner.

The present invention provides an apparatus and method for determining the magnitude of linear and rotational acceleration of an impact to a body part. The apparatus can be used with protective sports equipment, such as a sports helmet, wherein the apparatus includes a battery, a number of accelerometers positioned proximate to the outer surface of the head, and an electronic device with a processor and a transmitter to transmit data received from the accelerometers. To maximize the battery life and minimize power consumption by the electronic device, the apparatus includes a power management system with a sensor assembly. The sensor assembly sends a first signal to the electronic device to initiate operation when the sensor assembly detects the presence of an object with the helmet, and a second signal to the electronic device to cease operation when the sensor assembly detects the absence of the object.

A method to identify a water flow anomaly in a system having first and second water using devices to generate baseline data that preferably has water use signatures and corresponding water pressure information regarding the water using devices; comparing the baseline data with actual water usage signatures and corresponding actual water pressure information to identify a flow anomaly with the water using devices; and providing information on the flow anomaly to an individual. It is especially contemplated that baseline data are generated for multiple devices coupled to a common water supply system, with baseline data from two or more water using devices compared against future water use patterns of the same devices. Apparatus to accomplish these tasks is preferably housed in an irrigation controller, which may be advantageously coupled to a flow meter.
