Brake Pad Prognosis System
A method for providing an estimate of brake pad thickness. The method employs fusion of sensors, if used, and driver brake modeling to predict the vehicle brake pad life. An algorithm is employed that uses various inputs, such as brake pad friction material properties, brake pad cooling rate, brake temperature, vehicle mass, road grade, weight distribution, brake pressure, brake energy, braking power, etc. to provide the estimation. The method calculates brake work using total work minus losses, such as aerodynamic drag resistance, engine braking and / or braking power as braking torque times velocity divided by rolling resistance to determine the brake rotor and lining temperature. The method then uses the brake temperature to determine the brake pad wear, where the wear is accumulated for each braking event. A brake pad sensor can be included to provide one or more indications of brake pad thickness from which the estimation can be revised.

Method for sensing the presence of a human body part within a region of a machine tool
A detection system senses the location of a preselected color within one or more monitored zones of a machine tool. If the operator of a machine tool wears a red glove, the system detects the location of the color red and defines various monitored zones through the use of synchronization signals and a time circuit. The system can take action based on the location of the particular monitored zones in which the red glove is sensed. These actions can include the sounding of a horn, the lighting of a light, or the deactivation of the machine tool.
