Title: Fuel cell stack coolant conductivity sensor using differential voltage measurements
Inventor: HORTOP MATTHEW K
IPC: H01M8/10
Filed: 2001-11-06
Abstract: A method and apparatus for detecting leakage current in the coolant of a fuel cell stack. The invention eliminates the use of a conductivity sensor by using a voltmeter to measure the voltage across the coolant. If the coolant voltage is at or below a predetermined level, an excessive level of conductivity in the coolant exists, and the presence of leakage current is reported. The invention can also compare the coolant voltage to two different predetermined voltage levels, the second one higher than the first. A coolant voltage at or below the lower voltage level could signal a shut down of the stack, while a coolant voltage at or below the higher voltage level could signal an alarm or another diagnostic. The invention can optionally use a second voltmeter to measure the voltage across the stack and calculate the resistivity and conductivity of the coolant.

Title: Method for controlling the delivery of lubricant
Inventor: GUNACKER RICHARD
IPC: F16N29/02
Filed: 2001-08-10
Abstract: The invention relates to a method for controlling the delivery of lubricant between two parts that can be moved in relation to one another, especially for lubricating rails, above all in curved tracks, in order to prevent or reduce squeaking noises. To this end, at least one sensor, e.g. a microphone, is provided for picking up acoustic vibrations, especially body acoustic vibrations. The signal of said sensor is fed to a selective amplifier, e.g. to an active bandpass filter, and is used as an actuating variable for initiating the delivery of lubricant. In doing this, at least two frequency bands are filtered out, the intensities of the acoustic vibrations of the filtered frequency bands are compared to one another, and the determined difference or the ratio of the determined values is used as an actuating variable.
