Abstract: A flow measuring device, comprising a container for receiving a flow of liquid, a plurality of optical sensors associated with the container, each of the plurality of optical sensors producing an output signal dependent upon the presence of liquid reaching a level in the container associated with each optical sensor, means for modifying the output signal in accordance with at least one predetermined temperature compensation factor, and means for calculating a flow rate from the time at which the liquid traverses between two levels in the container.

Abstract: A system and method for analyzing a device that includes a mass configured for motion. The system includes a tri-axial accelerometer disposed to detect acceleration vectors of the device and to output three channels of acceleration data, and a user interface receiving the three channels of acceleration data. The user interface is configured to correlate the three channels of acceleration data with a reference frame defined by three orthogonal axes intersecting at a vertex, and includes a display and a selector. The display shows sets of options that represent dispositions of the device with respect to gravity, placements of the tri-axial accelerometer with respect to the device, and orientations of the tri-axial accelerometer with respect to the device. The selector selects one device disposition option, one tri-axial accelerometer placement option, and one tri-axial accelerometer orientation option.

Abstract: A computer-based apparatus for the collection, processing and distribution of electrical data, having a substantially sealed shell capable of resisting environmental contamination. The shell having a plurality of ports with each port configured to couple to an electrical probe, wherein within the shell are disposed, at least the following: a data acquisition system coupled to the ports, a processing system coupled to the data acquisition system, and a communication system coupled to the processing system.
