Abstract: A food holding apparatus and associated components and methods. The food holding apparatus includes a food holding unit and at least one food pan transporter. A food pan is stowable in a food pan receiving location of the food holding apparatus. The food pan is moveable by the pan transporter into and out of the food pan receiving location.

Abstract: A system and method of determining a target gas concentrations in a fluid environment using a gas sensor that improves the efficiency and accuracy of the gas sensor's measurements by taking measurements of electrical characteristics of the gas sensor at different temperatures, taking measurements during a transition between a first temperature and a second temperature, taking more frequent measurements, detecting when the gas sensor has reached equilibrium, using multiple sensors, accounting for offsets and drifts, reducing the time the sensor is not live, using various algorithms, or any combination thereof.

Abstract: A differential mechanism, connected to a driveshaft, transmits power to two halfshafts laterally directed toward the driven wheels of a motor vehicle. Each halfshaft is driveably connected to a pinion, which continually engages a gear fixed to an axle shaft, the pinion and gear forming a speed reduction gearset located between the halfshaft and axle shaft. Each gearset is located in a drop gear housing. Opposite axial ends of each halfshaft are fixed to a differential housing and the drop gear housing. Two extension tubes, each press fitted in the differential housing and a corresponding drop gear housing, provide structural continuity therebetween.
