Abstract: A wheel rim polishing tool simplifies the process of polishing tractor trailer wheel rims. The tool also reduces polishing time by polishing more surface area of the wheel rim per rotation as compared to what can be accomplished by hand or by means of a drill adapted with a polishing head. The tool further keeps the cost of polishing the wheel rims low by making a trip to a metal specialty shop no longer necessary. The wheel rim polishing tool is a portable device that allows the tractor trailer owner to polish their wheel rims quickly and easily.

Abstract: A vital signs monitor comprising a first device capable of being disposed at a selected location on a patient to pass at least exhaled gases therethrough; a second device coupled to the first device to perform a plurality of resistive measurements of certain predetermined parameters of the exhaled gases and a plurality of optical absorption measurements of other predetermined parameters of the exhaled gases; and a third device coupled to the second device responsive to the plurality of resistive measurements and the plurality of optical absorption measurements to provide individual read outs of at least a value of carbon dioxide in the exhaled gases, a value of tidal volume of the exhaled gases and a value of a respiration rate of the patient.

Abstract: In a first embodiment, the device is in the form of a face mask for affixing to the face of a patient to monitor the patient's respiration. It is self-powered and self-contained so that such respiration can be monitored all the while the patient is being transported. It incorporates light-emitting diodes which are illuminated, sequentially, to evidence regular breathing. When the patient stops breathing, the diodes do not illuminate, and an audible alarm is sounded to make medical personnel immediately aware of the breathing cessation.
