Patent ID: 8746068

Claim:
A handheld, lubrication dispensing apparatus for lubricating bearings of a machine with moving parts, comprising: a lubrication dispensing device capable of dispensing lubrication upon receipt of a start signal and ceasing lubrication upon receipt of a stop signal; a lubrication flow sensor to measure an amount of lubrication dispensed from the dispensing device and output information related to the measured amount of lubrication dispensed as data; a database, the data from the lubrication flow sensor being stored in the database; an ultrasonic detection device which detects an amplitude of ultrasonic energy emitted by the machine when its parts are moving and produces a signal related thereto; a control module which analyzes the amplitude of the signal from the ultrasonic detection device and determines, in real time, a necessary amount of lubrication that needs to be dispensed in order to properly lubricate at least one of said bearings, said control module being configured to use the data from the lubrication flow sensor, to determine when the necessary amount of lubrication has been dispensed from the lubrication dispensing device to properly lubricate the machine, and to provide the stop signal to the lubrication dispensing device when the necessary amount has been dispensed.
